“LAB TESTS ARE GREAT. BUT IT’S HIGH-VOLUME PRODUCTION THAT WILL
REALLY PUT A SMILE ON MY FACE. I’ve heard some impressive-sounding announcements about recent laboratory successes in converting my energy into electricity. But to make solar power the global resource it’s capable of becoming, you’re going to have to expand on those lab results with high volume panel production. And you’re going to have to deploy those panels on a massive, worldwide scale. I’m talking gigantic panels. Lots of them. Everywhere. Which is where Applied Materials comes in. They’ve spent the last 40 years mastering the challenge of taking scientific breakthroughs and scaling them into commercialized products, at lower and lower prices, year after year. Now they’re doing for solar panels what they’ve already done for computer chips and flat panel displays. I mean, they can already deliver 5.7m 2 thin film solar panels at over 8% efficiency in high volume production. Which makes me one happy mid-sized star.”

editor’s note It’s been an interesting year. As 2009 slowly comes to a close—a year mixed with concern and hope, at least given the North American economy—renewable energy seems to be holding its own. Despite a lull in wind turbine manufacturing, the American Wind Energy Association announced in its (Q3) market report that the wind energy industry installed 1,649 MW of new power generating capacity in the third quarter, bringing the total capacity added this year to over 5,800 MW (an amount higher than the second quarter of 2009 or the third quarter of 2008). The fourth quarter of 2009 is not expected to be as strong as ’08 but, nevertheless, the total wind power capacity operating in the US is now over 31,000 MW, generating enough electricity to power the equivalent of nearly nine million homes (www.awea.org). In terms of geothermal power, the US continues to lead the world in online energy capacity and, according the Geothermal Energy Association (www.geo-energy.org), continues to be one of the principal countries generating growth—as of October, the US had a total installed capacity of 3152.72 MW. Bound to help with that number: the recent $338 million in Recovery Act funding from the Department of Energy (DOE) for the exploration and development of new geothermal fields and research. These grants will support 123 projects in 39 states, and will be matched more than one-forone with an additional $353 million in private and non-federal cost-share funds. The present and future also looks good for hydropower, with $30.6 million allocated to hydroelectric projects and another $50 million for water power R&D from the DOE. A study released by the National Hydropower Association (www.hydro. org) claims the US industry could install between 23,000 MW and 60,000 MW of
additional capacity by 2025, or enough to generate electricity for 31 million additional homes. Currently, the US has about 78,000 MW installed capacity of conventional hydropower, which provides enough electricity to power more than 27 million homes and serve 75 million people. Having recently attended Solar Power International in Anaheim, California this October, solar energy is certainly becoming more viable and cost-friendly, as well. Named one of Trade Show Week’s “Fastest 50” growing conferences, the event itself broke attendance records, hosting more than 24,000 industry professionals, a notable increase from the previous year. According to Rhone Resch, president and CEO of SEIA, “The size and scope of Solar Power International reflects solar energy’s potential as an engine of economic growth.” (Check out Resch’s “Solar Bill of Rights” at www.seia.org). As of press time, renewable energy predictions for 2010 are only beginning to surface. Deloitte, a business advisory firm, forecasts that smart grids will take the world by storm next year as annual global spending on the technology will jump to $33 billion by 2014 (it was $12 billion in 2008). Deloitte also anticipates that oil-producing countries will become hot sources for renewable energy. Close proximity to European markets, abundant cash to invest from oil revenues, and ideal weather conditions, especially for solar power, could majorly pay off (www.deloit.com). Your thoughts? This issue, we focus on the expedition of the loan guarantees program for renewables, energy investments, solar incentives, and more. And, don’t miss our 2010 Wind Buyers Guide—a perfect place to plan for the New Year.
Sincerely, Michelle Froese
news bites SmartGridLicense.com This new website serves as a resource for utilities and other industries seeking information about licensing technology that fosters development of the Smart Grid, an infrastructure that allows utilities to optimize the grid for resource deployment and encourages a change in consumer behavior by helping to deliver long-term savings. The Smart Grid is also designed to reduce greenhouse-gas emissions to bolster air quality. “The power of the Smart Grid lies in its ability to leverage the Internet and wireless signals to allow various components to ‘talk’ to each other,” explained T David Petite, CEO of SIPCO LLC and a pioneer of Smart Metering technology. “Appliances like refrigerators and washing machines can ‘talk’ to the meter, or an entire neighborhood of meters can even ‘talk’ to each other. This means utilities no longer have to project resource needs based on historic consumption—for example, with wireless mesh technology, they can better monitor consumption usage and control home devices in more real-time.” More than eight million Smart Meters are currently deployed throughout the US, and the market for residential energy management has taken the first significant steps in deploying Smart Grid technologies and advanced meter infrastructure on a broad scale. In addition, the federal stimulus bill allocates $11 billion for Smart Grid initiatives through 2010, with the Obama administration’s support.

“I’d like to thank you and Stefan Braendle for the excellent article on solar thermal in Volume 3, Issue 4. I’ve been in the solar thermal industry since 1981 and continue to fight misconceptions that PV is all that solar is. I’d like to also point out two even larger installations of solar thermal in North America. While both are in Mexico, they are for totally different applications. The first for pool heating is over 700 collectors (2,100 sq. m). An even larger system installed just earlier this year is for process pre-heating for a Nestle chocolate plant featuring over 900 collectors (2,700 sq. m.).” Dave Sizelove, President & CEO Aquatherm Industries, Inc.

Stimulus and Response The loan guarantee program moves ahead By Ed Feo | Partner, Milbank Tweed Hadley & McCloy LLP
T
he renewable energy finance story of the year is the emergence of the federal government as the financial prime mover. The Treasury grant program in Section 1603 of the American Recovery and Reinvestment Act (“ARRA”) has proven to be a powerful tool in leveraging new investment and financings. The Department of Energy (“DoE”) has accelerated its grant program for new energy technologies with funds being provided for new generation, smart grid, energy efficiency, and fuels solutions. And, finally, the DoE loan guarantee program under Title XVII of the Energy Policy Act of 2005 has gained momentum with new solicitations in July and early October. Last column addressed the DoE loan guarantee solicitations issued in late July. These solicitations were for large transmission projects and innovative technology generation projects. At that time, the initial filing dates under the July solicitations had not yet occurred. With those dates now passed, sponsors with qualifying projects are queuing up by the dozens at the DoE’s door. The definition of “new or significantly improved technologies” is especially helpful to technologies that have been deployed outside of the United States on a commercial basis, but not yet so deployed here. Expect to see a number of large-scale solar projects benefitting from this program.
The benefit to equity from the program will come from the reduced debt cost and greater tenor of financing capable with a loan guarantee. The DoE offers 100% loan guarantees under July innovative technology solicitation. Funding will come from the Federal Financing Bank (“FFB”). In those transactions, the DoE and FFB are the only credit parties and perform their own due diligence, credit assessment, and underwriting. This program does not have to deal with the intercreditor issues arising under the new Section 1705 program implemented under ARRA—the partial guarantee of loans to commercial renewable energy technologies. On October 7th, 2009, DoE issued its first solicitation under Section 1705 for guarantees of up to 80% of the debt financing for commercial renewable energy technology projects. Manufacturing facilities are not included in this solicitation. The solicitation establishes a series of ten application dates, starting on November 23rd, 2009. The program will apply $750 million of funds allocated under ARRA to pay for the credit subsidy costs of the loan guarantees. The credit subsidy cost is the premium paid to DoE to issue the guarantee. Estimates of the amount of guaranteed loans vary widely, based on the assumed amount of the credit subsidy cost— some industry experts suggest as high as $15 billion. 8

Both project level and corporate level financings will qualify for this program. Guarantees generally are available only for construction projects, although a takeout financing of another construction loan might qualify if there is no other term financing available to the project. The new solicitation defines “commercial technology” as technology in use in three or more projects anywhere in the same or substantially similar application for a period of at least two years. The time periods and geographic scope are different than the innovative technology definition for the July solicitation (requiring no more than three projects in operation in the US for more than five years). A technology could qualify as both innovative and commercial under the different solicitations depending on the extent and timing of deployment. Under the October solicitation, DoE will work directly with qualified financial institutions in the Financial Institution Partnership Program (“FIPP”). Under this program, eligible lenders (not the borrower) will apply to the DoE for the loan guarantee. The lender applicant is obligated to perform a due diligence review and credit assessment consistent with its standard internal policies applied in making loans where no guarantee is issued. The lender applicant (and each proposed other entity providing financing) must provide a financing commitment as part of the guarantee application. The solicitation is geared to a simple senior secured bank or institutional financing. However, the definitions of “lead lender” and “holder” of the guaranteed obligations are sufficiently flexible to contemplate capital markets and securitization structures. One objective of the FIPP is to underwrite transactions that have credit ratings of BB or the equivalent. The lender applicant must obtain and submit a credit rating for the proposed transaction as part of its application. This level of credit rating is typical for most senior secured debt financings, although it is not market practice to obtain credit ratings in privately financed debt transactions. Applications will be evaluated by DoE on a competitive basis and scored for programmatic factors (especially readiness of the project for financing and simplicity of structure), creditworthiness (financial strength and security of revenues), and financing and funding plan (ability of the financing parties to close the deal). The solicitation goes to great lengths to emphasize that simple financing structures and “shovel readiness” are critical factors in light of the ARRA requirement for construction to commence by September 30th, 2011. Commencement of construction means the borrower has completed all engineering and has obtained all permits, engaged all contractors necessary to build the project, and commenced physical construction on the site. Title XVII requires a project obtaining the benefit of a loan guarantee comply with the National Environmental Policy Act (“NEPA”). The new solicitation notes that, given the outside date for commencement of construction, projects requiring an environmental assessment (instead of a full environmental impact statement) are more likely to qualify for a loan guarantee. Many projects that have not previously
had to do a NEPA review will be doing one now. The loan guarantee will cover no more than 80% of the debt. This program will require the holders of guaranteed loans to keep the uncovered portion as well, with transfers requiring DoE consent. Any transfer must maintain the pro rata relationship between guaranteed and unguaranteed obligations. DoE also makes all decisions as to the guaranteed obligations (including the exercise of remedies), except for a consent right of holders as to amendments of basic financial terms and the right of two thirds of the holders to direct remedies on an extended borrower event of default if DoE fails to act. This new solicitation presents a narrow gate in terms of readiness, creditworthiness, and environmental compliance, but has the potential to be of great benefit to qualifying projects. The firmness of the requirements of this program is remarkable given the flexibility on “readiness” evidenced in the prior solicitations. But this program is all about stimulus and the ability to get construction moving. Although initially skeptical about the likelihood of sponsors wanting to go through this program, given its stringent requirements, we are seeing a tremendous amount of interest from sponsors in getting the ‘part one’ applications on file as soon as possible. Of course, the stimulus effect here is not to finance projects that would not otherwise be financed. In fact, the effect is quite opposite: projects that will qualify for this program will likely qualify for financing in the private market. The stimulus effect should come, if at all, from the potential enhanced equity returns afforded to qualified projects, as well as from greater leveraging of private debt financing sources. One could say the program makes the rich richer, but the policy decision to support that outcome was passed with ARRA earlier this year. The benefit to equity from the program will come from the reduced debt cost and greater tenor of financing capable with a loan guarantee. The net present value of the project to the equity sponsor improves with lower debt service payments. That improved equity return means more cash flow to the sponsor, or a higher price on the sale of interests in the project. Presumably, those additional funds can be used for other renewable energy project investments. Leveraging the private finance market will occur in two ways. One is that more lenders will participate in renewable energy finance given the availability of the guarantee. This seems somewhat at odds with the notion that the deals should be underwritable without the guarantee (in effect, the lenders are being asked to
evaluate the credit blind to the guarantee). But, as a practical matter, we are seeing new funding sources being attracted because of the potential guarantee. The effect of the guarantee cannot be isolated in a vacuum. The other benefit will be that lenders will have more capital available given the lower reserve requirements of a guaranteed loan. So, we should expect growth in the capacity of the debt markets as a result of the program. It has been an interesting year. The year commenced with the financial markets in disarray. ARRA was passed in February and commenced the new era of federalization of renew-
able energy project finance. The Treasury grant has shown the potential to completely change the basis for federal support from a tax subsidy to a cash subsidy. Finally, we are seeing the DoE loan guarantee program with the potential to finance billions of dollars of projects in 2010. Amazing change in a short period of time.

Evaluating Solar Energy Plants to Support Investment Decisions By Marie Schnitzer
A
s solar projects increase in quantity and scale, capital to fund projects will be increasingly challenging to acquire. Coupled with tighter capital markets, an accurate resource and energy production analysis plays a critical role in presenting a “bankable” report to financial institutions. Several key inputs are used for the analysis: solar resource assessment, energy production projections, and their associated uncertainties. Financeable independent energy production estimates utilize thoroughly screened resource data, solar system design specifications, and projectspecific loss factors and uncertainties to estimate both the expected production of the plant and the corresponding uncertainty to provide several probability levels quantifying financial risk. The first step in assessing the solar resource to screen sites for potential development is to review the modeled data sets. The most widely available dataset from National Renewable Energy Laboratories is the National Solar Radiation Database; however, as the data resolution is 10km, a more rigorous approach is needed to create representative site-specific solar resource data with reduced uncertainty. The satellite imagery conversion process and its coarse resolution does not take into account subgrid scale (such as terrain-induced) climate effects resulting in uncertainty ranges from 8% to greater than 25%. Although this level of uncertainty may be acceptable for prospecting and screening or for smaller scale projects, with an increase in project size from tens to hundreds of megawatts, additional on-site measurements are needed to mitigate project risks by characterizing the site to a greater degree. Another source used to evaluate the solar resource of a particular location is long-term reference stations, which record meteorological data throughout the United States. Though there is a vast network of these stations, in the southwestern US (an area of great interest and activity for developers), there are only four long-term reference stations with solar resource measurement capabilities: Hanford, CA; Mercury Desert Rock, NV; Albuquerque, NM; and El Paso, TX. This network does not provide many opportunities to determine site characteristics within an area of significant activity in prospecting and development, furthering the need to conduct on-site measurements. The observations obtained from on-site resource assessment campaigns provide extremely valuable data to develop and design solar energy projects. Instrumentation should measure minimally global horizontal and diffuse radiation, wind speed and direction, temperature, and relative humidity. On-site campaigns that utilize solar meteorological stations provide micro-siting data that is valuable in characterizing the solar resource to reduce the overall uncertainty of the energy analysis. Data from solar meteorological stations needs quality control to remove errors that may lead to biased or misleading energy production results. All data obtained should be validated using established procedures to ensure high data quality. A typical meteorological year (TMY) is defined as a long-term annualized hourly time series of insolation and relevant meteorological parameters chosen from a typical monthly time series of historical observations. Through data analysis and validation, biases and anomalies can be identified in any of the datasets available in the NRSDB and other weather databases. Once on-site data has been validated, applying the measure-correlate-predict (MCP) method is useful in reducing the uncertainty in projecting the long-term solar resource. In MCP, a linear regression or other relationship is established between a target site, spanning a relatively short time period, and a reference site, spanning a much longer time period. The complete record of the reference station is then used in this relationship to estimate the long-term historical climate at the target site. 10

AWS Truewind, a renewable energy consulting firm, recommends an on-site period of record of six to twelve months for use in the MCP process. Energy production projections
Evaluating solar energy production can vary in complexity and are based on a range of variables used to predict performance under operating conditions. Important factors include the use of computer simulation models, solar resource characterization, system specifications, power plant losses, and the uncertainties associated with each of these issues. Computer simulation models should be evaluated and developed carefully to ensure the most accurate simulation of energy production. The capabilities of publicly and commercially available models vary significantly using different meteorological and equipment databases, radiation and system simulation models, and loss factors. These simulation models are limited in capability to evaluate project uncertainty and further steps are needed to complete a bankable report with probability levels (e.g. P50, P90, P99). Essential elements are simulation models and calculators created, then used in conjunction with the commercial software programs. This provides the opportunity to customize simulation models to accommodate for uncertainty calculations, integrate lessons learned, or increase functionality of the stand-alone model. A site-specific TMY is an essential element for accurate energy calculations. The meteorological files included in the publicly or commercially available simulation model databases usually have a coarse resolution and do not offer data for the exact project location. These database files provide a method for screening and prospecting and are not recommended for use in a detailed system analysis as the use of meteorological data found in the database can introduce a bias of several percent in annual energy production. There are considerations for the type of plant and meteorological data needs between a CSP or solar thermal and PV plants. The system equipment, component arrangement, and module simulation model must be known to predict system performance at non-ideal conditions. For example, PV modules are rated at standard test conditions, which include solar irradiance of 1000 W/m2 and cell temperature of 25°C; however, the PV system rarely operates at these conditions. Radiation levels change constantly throughout the day and the PV cell temperature can much higher than 25°C for areas in southwestern US. PV systems operate in these non-ideal conditions much of the time, so the model used to simulate PV performance must be able to adjust the system’s performance accordingly. The simulation model should calculate module temperature (using irradiation, wind speed, ambient temperature, and mounting structure) and adjust performance using a validated correction model. For PV systems, the performance of the inverter must be simulated for different operating scenarios. Inverter performance is typically described using an efficiency curve (efficiency versus percentage of nominal power). The curve expresses a combination of electrical and maximum power point tracking efficiency. This generalized performance indicator is satisfactory for initial performance estimates; however, inverter performance will change with different operating conditions and system voltages. Also, the efficiencies stated in the inverter curve are generalized for a typical module; the ability for the inverter to track the maximum power point of the system will depend on module technology, since different modules have more/less pronounced maximum power points depending on their current-voltage curves. An important step in the energy prediction process is accurately quantifying the environmental and system losses. These losses will greatly impact the performance of the system. While some of these are static losses, some change with time and others are dynamic. To produce accurate
estimates for system performance, these losses need to be assessed for the specific components of the system and the exact project location. Uncertainty
Each step in the energy production analysis increases the uncertainty of the end result; therefore, it is important to quantify this uncertainty at each step of the process to produce an accurate range of production values with associated probability levels. The main sources of uncertainty exist in the solar resource datasets used to create the TMY the simulation model’s algorithms, the solar plant estimated losses, and the tolerance in the manufacturer supplied power and electrical characteristics of the system components. The TMY uncertainty includes those from the NSRDB dataset, long-term reference station datum, and on-site measurement campaigns. On-site measurement campaign uncertainty includes that from the measurement equipment accuracy, installation, and maintenance protocols, proximity to actual project siting, and equipment calibration. The computer simulation model’s uncertainties include the translation of horizontal radiation to the plane of array, estimation of module temperature, and an accurate representation of module performance in non-ideal conditions. There are also varying uncertainties in estimating each of the environmental and system loss factors outlined above. The uncertainty of estimated system performance increases with each step of the solar resource and energy assessment process. All of the noted uncertainties are combined into an overall project uncertainty that is used to calculate various probability levels for the annual production of the system (P50, P75, P90, P90, and P99). In combination with the annual degradation of system performance, the probability levels are used to calculate annual energy estimates for each year of the project’s expected lifetime. Additionally, two table matrices of average net production on monthly and diurnal time scales is provided to demonstrate expected system performance throughout the year, allowing load matching and more detailed economic studies. Conducting a thorough solar production assessment requires the input of numerous key variables. The first variable is an accurate and representative solar resource assessment to create the TMY dataset with a solar resource measurement campaign as a key component. Imperfect data and models, complex cloud or solar climates, and other factors combine to create significant uncertainties in energy production estimates. A second variable is a carefully reviewed energy production estimate simulation model that takes into account system specifications, as well as
environmental and system losses. The third variable in the production assessment is a thorough understanding of the sources of uncertainty to develop the probability levels for the annual production of the system. Strategies to mitigate them are critical to providing well characterized energy production
predictions in support of overall risk quantification for financial participants in the project.

Driving Down the Cost of Solar Energy With use of an inclinometer By Mohit Abraham
C
oncentrated solar power (CSP) and concentrated photovoltaic (CPV) methodologies generate electricity by focusing a large amount of sunlight onto a much smaller area. To maximize efficiency, the focused sunlight needs to be accurately positioned. Being off by even a single degree could result in a significant drop in efficiency, and the biggest impact to the cost of delivering solar energy is efficiency. As with most systems, the accuracy is limited by the accuracy of the sensors used in that system. There are a number of different types of sensors that can be used in these systems. The following suggests how to maximize the accuracy of any system that tracks the elevation of the sun and how to do it cost-effectively using inclinometers. Concentrating solar systems overview
CSP and CPV systems track the sun throughout the day to increase the total energy output. Such systems can see as much as a 40% increase in output as compared to fixed position systems. The tracking systems can have either a single axis of rotation (parabolic trough and linear Fresnel mirror array), or two axes of rotation (central tower systems with heliostats, CPV, and dish/engine systems). So, although the systems with dual-axes trackers need to track the azimuth of the sun, both systems track the elevation.

Inclinometers versus encoders
For tracking the elevation, several basic kinds of sensors can be used. If a motor is used, a rotary encoder would be a possible solution. If a linear actuator is used, then a linear encoder could be used. With both solutions, the control software requires an algorithm to translate the rotation of the motor or the distance extended by the actuator to the tilt angle of the mirror being controlled. There must also be checks in place to compensate for backlash or other irregularities in the system mechanics. The truer feedback device would be an inclinometer. The inclinometer directly measures the actual angle of tilt with respect to gravity. When it is mounted on the side of the mirror, the controller receives the actual position of the mirror. This angle is independent of the kind of actuator used in the system and any irregularities in the mechanics are transparent to the controller. The control software now becomes much more
straightforward. There is
also added confidence in the controller because the feed back signal is taken from the output of the control loop as opposed to from within the system.

Inclinometers: high accuracy & high resolution sensor
Inclinometers are typically either a mechanical or solid state device. Mechanical inclinometers have some sort of weighted pendulum to reference gravity so that when the inclinometer is tilted, the pendulum swings down and the amount it swings is the angle output of the sensor. This pendulum would have to be damped and would also have to be mounted with bearings. As a result of the friction in the bearings, there is a limit on how small a movement the inclinometer can detect. This effect is called stiction, and it restricts the resolution and accuracy of the inclinometer. Solid state inclinometers have no mechanical moving parts and do not have any errors due to stiction, which makes them ideal for solar trackers where frequent small changes are made. For example, US Digital’s T7 inclinometer was characterized for movements of 0.1°, and a cumulative distribution showed that the maximum DNL error is under 0.02°. With an incremental inclinometer, the output represents a change in angle; however, an absolute inclinometer reports the actual angle as the controller will know at all times the actual position of the mirror. Since the output is absolute, a home cycle at power up is not needed, even if the mirror was moved while power was off. The chart

below shows the measured accuracy for a typical T7 absolute inclinometer over a full 360° range. Low Cost of Installation
Another big advantage of inclinometers is the low cost of installation. There is no need for a shaft coupling to mount the device to a drive shaft. The T7 is hermetically sealed and can easily be mounted on the side of a parabolic trough or a mirror with four screws or bolts. This decreases material and labor cost during installation. With the zero point of the T7 inclinometer being set programmatically, the initial mounting position is not critical, cutting down on mounting time.

Conclusion
With continually increasing pressure on systems to maximize efficiency, the performance of solar trackers becomes ever more critical. As each system component is carefully chosen and scrutinized, choosing the right sensor is crucial. The advent of new solid state inclinometers provides control engineers with a technology breakthrough in performance, simplicity, and low cost. For solar trackers, absolute solid state inclinometers have the features needed to make that technology stand out. The combination of high accuracy, high reliability, ease of installation, and use makes the T7 the ideal inclinometer to drive down the cost of solar energy in concentrated solar power systems.

solar energy Renewable Energy in Europe & the US A study on the difference in incentive programs By Simon Geishussler

government incentive programs that include feedin tariffs and building codes that encourage energy conservation. The US has lost much of the leadership position it once held, primarily as a result of an inconsistent and confused stimulus environment. In recent years, renewable energy has been promoted by various types of subsidy programs. On one hand, this stems from a general shift in the awareness of the public, which has been taken over from political leaders. On the other hand, it is clearly visible that countries who invest a lot of money in accelerating renewable energy deployment also succeed in creating a large number of attractive jobs. From the viewpoint of the homeowner that plans to install a solar or geothermal system, however, incentive and grant programs are a difficult jungle to navigate. Country, state, and communal programs make it virtually impossible to mention generally applicable numbers since subsidies can substantially contribute to the profitability of a solar system. Effect on the local and regional industry
Germany, Europeâ&#x20AC;&#x2122;s biggest renewable energy market, has managed to combine incentives for renewable energy and energy efficiency into one program; whereas, most US programs concentrate on solar only, neglecting other important facets like energy efficiency or offering separate programs for efficient energy usage. Germany is based on the EEG, Germanyâ&#x20AC;&#x2122;s Renewable Energy Law, with the clear aim of reaching a target of 12.5% renewable energy by 2010 and 20% by 2020. The main background of these regulations is similar to those in the US: energy independency, sustainable energy policy, and support of technology innovation. â&#x20AC;&#x153;How much is the rebate in my case?â&#x20AC;?

Funded by the US Department of Energy, the Database of State Incentives for Renewables & Efficiency project was created in 1995, and is the most upto-date source for information regarding subsidies in the US. The DSIRE is based on four pillars of cost-effective solar policy: incentives, net metering, interconnection, and utility rates and policies. Their website (www.dsireusa.org) provides a comprehensive data for state, local, utility, and federal rebate programs, incentives and policies that promote renewable energy and energy efficiency. Planners and installers are taking an important role in advising homeowners in the early design stage, when it is important to estimate the solar energy generation or, in case of a geothermal system, the energy gained from the earth. Planners often rely on simulation tools (such as Vela Solarisâ&#x20AC;&#x2122; Polysun), as they can guarantee a certain quality level for their service and gain the trust of the customer. Solar thermal and energy efďŹ ciency
In lieu of tax credits, the Incentives Commercial Solar (ITC) Grants program was recently passed in the US with grants equivalent to 30% of the installed cost available through 2010. Germany, alternatively, has clear guidelines of basic subsidy per square meter of installed collector or 14

per total system installed. Depending on the system size and application type (solar hot water, space heating, solar electricity, process energy, solar cooling), different incentive rates are taken. If a homeowner replaces an old, inefficient furnace with a new, modulating condensing furnace, an extra bonus or subsidy is given. Another bonus may be applied for combination of solar with biomass (e.g. wood furnace) for special system efficiency, the combination of solar hot water and solar space heating, and innovation projects. Most importantly, building insulation is taken into account. For example, if a landlord reduces heat losses and respectively manages to reduce the heating or cooling energy demand (through improvements like better insulation or new windows) by 30%, extra bonuses are granted. Countrywide insulation standards like the German Passiv Haus, which define clear energy consumption values per square meters of living area, are standard. The US does not have such clear building standards. In Europe, as opposed to the US, an independent third party approves the improvements and solar gains to get a subsidy by the state. The use of simulation software is often required or strongly recommended to get the grants as the software reports contain all information and prove energy efficiency, solar gains, and other improvements. Feed-in tariffs and subsidies for PV systems
US net metering allows customers to store any excess electricity generated, usually in the form of a kilowatt hour (kWh) credit, on the grid for later use. This is available in 39 states, and each statesâ&#x20AC;&#x2122; policies vary dramatically. The best policies have been adopted by Colorado, Maryland, Florida, New Jersey, and Oregon according to the Interstate Renewable Energy Council. Whereas in Europe most countries offer a fixed rate per kWh of energy fed onto the grid, called a feed-in tariff, most US states only allow energy to be stored on the grid, and no payment for excess energy is granted. A US homeowner, therefore, has no incentive to install large PV fields on the roof. German and French utility companies are required to guarantee a fixed rate per kWh. Germanyâ&#x20AC;&#x2122;s rates have consistently decreased over the years, with digression policy at 8% in the first two years after installation and 9% in the following years for installation up to 100KW. The German government indirectly sets the price for PV modules as planning bureaus and manufacturers offer PV installations for a value it is still profitable to the landlord. Effects on the work of contractors and the buying decision
The lack of beneficial incentive programs in the United States is at the core of why the country has fallen behind global leaders in energy efficiency programs:
ProďŹ ler for solar cell manufacturing KIC announces the SunKIC version 1.1.0, a thermal profiler that is specifically designed for the unique needs and challenges of the PV industry. The SunKIC benefits from several hardware and software innovations that help solar cell manufacturers acquire insightful data on their thermal processes. The compact form factor (19 millimeter/0.75" tall thermal shield) enables the SunKIC to accommodate the tight width and height restrictions of the metallization furnace tunnel clearance. And, the flexible, easy-to-use graphical navigation software makes for quick and convenient profiling.
A California PV contractor does not have any incentives to advise a homeowner to reduce electricity demand. The higher the electricity demand of the home, the larger the PV installation the contractor can sell, which is a direct effect of the net metering system not paying for extra electricity fed on the grid. It is also an effect of inadequate third party control of the system efficiency. Many California buildings are equipped with large PV fields, heating water with expensive, PV-produced energy. PV has an efficiency of 11% from sun to electricity; whereas, direct solar hot water heating through collectors has an efficiency of 40% to 80%. Heating water with PV-produced electricity is approximately four times as expensive as heating with solar collectors. This is the result of a lack of joint work between solar thermal and electric contractors, as well as the wrong incentive programs. Factors like building insulation and efficiency of boilers are equally important as solar energy. US grants often do not consider these crucial parts, resulting in systems that are not optimally designed. System design plays a big role when providing solar energy. Grants per system often do not guarantee solar gains. The best collector does not help when the system is poorly designed. A system simulation providing accurate system data for the particular site and guaranteeing solar gains is crucial, and should be considered before giving a subsidy. For the States to excel in renewable energy installations and programs, consumers, businesses, and organizations need better, more comprehensive incentives. European countries provide a good blueprint for engaging energy efficiency in a comprehensive way that the US should work towards.

Solar Assessment Districts By Warren Diven
C
alifornia has an abundance of sunshine, making solar energy a plausible energy generation option for many of the stateâ&#x20AC;&#x2122;s residents and businesses. But with the cost of adding solar panels to a home or business at approximately $30,000 or more, unfortunately, not everyone who wants solar energy can afford it. Realizing that cost is a major factor when deciding whether to upgrade a property to be more energy efficient, the state passed a bill that helps with the affordability issues. Assembly Bill 811, passed in September 2008, gives all California cities and counties the ability to offer low-interest loans to homeowners and commercial property owners for energy efficient projects and solar panels. The loans are offered through â&#x20AC;&#x153;sustainable energy financing districtsâ&#x20AC;? (also called solar or energy assessment districts) that are established by cities and counties. These districts offer loan programs that are user-friendly in that property owners are not strapped with large down payments or high interest rates. The loan is secured by contract assessments levied on the ownersâ&#x20AC;&#x2122; properties. Owners borrow money from a city or county participating in a contract assessment program to pay for their new energy efficient or energy generation products, and the long-term payment of the loans is linked to ownersâ&#x20AC;&#x2122; property taxes. A participating city or county may issue

bonds secured by the contract assessments to raise money for the loans, access general and re-development funds, or otherwise raise capital to fund such loans. AB 811 has many benefits for property owners not found in other forms of financing, such as home equity loans. These advantages include the fact that a contract assessment runs with the land and is not required to be paid off when a participating property is sold. There is little upfront cost for owners and, unlike a second mortgage or home equity loan, the process to receive approval of a loan secured by a contract assessment may require limited documentation. Because the loan payments are tied to property taxes, the interest portion of the loan payments is tax deductible. Some districts are devoted exclusively to one type of sustainable energy generation improvements while others will fund multiple types of projects, including solar, wind, or geothermal energy. Municipalities and counties throughout California are embracing the idea, and not only because it is a creative way for property owners to finance upgrades to their property. The programs also help cities and counties meet their mandated need to reduce greenhouse gases and be energy independent. The Sonoma County Energy Independence Program made its first loan in May 2009. A homeowner was granted a loan of $25,500 for a five kilowatt PV system. The county reports there are another $6 million of applications for loans pending. Under the program, commercial property owners are encouraged to â&#x20AC;&#x153;reduce operating and maintenance costs through investment in energy efficiency and renewable energy.â&#x20AC;? Palm Desert, in Southern California, was the first city in the state to establish such a district. Palm Desert city officials realized that their constituents needed help to finance private energy projects, which would help contribute to the cityâ&#x20AC;&#x2122;s five-year goal of cutting energy use by 30% by 2011. With a $1.5 million advance from the cityâ&#x20AC;&#x2122;s general fund, Palm Desertâ&#x20AC;&#x2122;s AB 811 program allows residential or commercial real property owners to immediately enjoy a greatly reduced electric bill with no out-ofpocket expenses. Under Palm Desertâ&#x20AC;&#x2122;s program, there is a minimum loan amount of $5,000, with no maximum limit. Property owners are not subject to credit ratings or a credit check. The interest rate is fixed at or near 7% and paid bi-annually (through assessment installment collected on the property tax bill). Loans can be used on a variety of energy efficient improvements, as well as the materials and labor required to properly install them. The process to establish an AB 811 program is multi-faceted and requires establishing the jurisdiction of the district, public hearings, designating the type of improvements to be financed, prioritizing the types of property owners who will receive financing, raising the capitol and marketing the program. Depending upon the staffing and budgetary resources, this process could take years. With the state facing unprecedented financial problems combined with the depressed real estate market, many municipalities may not place an AB 811 program at the top of their priority list. However, Californiaâ&#x20AC;&#x2122;s energy shortage is not a short-term dilemma. AB 811 programs offer a significant resource to energy conservation problems that will face the Golden State for years to come. Warren Diven is a partner with the law firm of Best Best & Krieger. A lawyer for 26 years, Diven specializes in public finance law, acting as lead counsel in engagements involving all types of financings or finance issues and has advised a number of the firmâ&#x20AC;&#x2122;s municipal clients on the establishment of AB 811 contract assessment programs.

Advances in Solar-charged Products By Steve Krausse
A
s designers of portable devices pack greater functionality into products, power management requirements have increased. Products require multiple supply rails, battery charging, and a variety of power management capabilities, all of which are implemented to maximize battery life. Portable power is the impetus for new battery developments, power management ICs, and energy harvesting techniques (vibration trans-
ducers, thermoelectrical converters, RF converters, and PV cells). Today, PV conversion of light into electricity remains the most effective way of harvesting ambient energy. Any portable products that typically use rechargeable batteries (lithium ion, NiCd) could have a solar cell added to their PC boards, and be charging constantly, when light is available. In each charging application, solar cells provide just enough current to hit the voltage limit—extending battery life, overcoming self-discharge problems, and providing an environmentally responsible solution. Many lowpower applications and devices spend the vast majority of their time in wait mode, only waking up periodically to perform a required function. Static displays and intermittent sensors that utilize a very small maintenance current are wellsuited to the use of solar cells to supplement battery power, recharge the battery between higher current operations, and extend battery life. Even the smallest remote sensing and data collection devices require some amount of current to operate even in standby mode. The need to provide small amounts of current over long periods has spawned new battery designs, and this work continues today. The other part of the power equation: providing additional power to maintain batteries as long as possible once the device is installed in the field. The use of solar technology is becoming an increasingly common source of energy and is an excellent choice for sensors used where light is available at regular intervals. Yet, for all of the various applications that could benefit from such energy harvesting, few manufacturers and designers have implemented solar charging for portable product batteries. Why? • Low efficiency. The efficiency of a PV cell is defined by the ratio of the electric energy generated by the cell and the energy of irradiance incident at the cell surface. Due to mobile operation and indoor use, light capture in PV-powered consumer products can be quite low. Further hampering the energy harvesting effort is that smaller electronics have limited space available to implant solar cells for enough light capture. • Inability to conform. PV cells must be lightweight, flexible, and capable of conforming to the design of the electronic device. Regular cells (typically designed in a package) cannot conform to curves; amorphous cells better conform to the design constraints of NACE1009 small consumer electronics. However, amorphous silicon’s efficiency is quite low (6% to 8%), and far below its chip competitor. • Voltage. The PV power source must reach battery voltage of 4v to 12v so as to ensure adequate recharging of bat-

teries. Individual solar cells typically produce between 0.3v and 0.6v. Solar cells must be packaged in a series, such as the panels for homes, to produce usable energy amounts. Even when packaged in a series, each cell only produces energy equal to the output of the lowest power cell. If a single cell is shaded, it affects the entire series. Such requirements make solar cells inflexible for use inside cell phones, remote controls, and other small devices.
able battery. Widespread adoption of this technology may take time. First movers are integrating the chip into myriad consumer/portable products in test environments. Until full-scale integration meets with broad success, the solar industry sits at a crossroads utilizing advanced technology to produce solar chargers.

PV cell technology
So, what is the solution? Photovoltaic cells (monocrystalline, high-efficiency solar cells) that incorporate an enhanced light-trapping surface have the potential to generate the voltage necessary to power batteries in all types of applications. Manufactured with Silicon-On-Insulator (SOI) process technology, a single chip could hold multiple solar cells in a series, so that a wide variety of voltages is possible. With 24 solar cells on a single chip, the semiconductor chip gives off 12v (when exposed to natural light), which is enough to power both rechargeable (nickel cadmium) and non-rechargeable (alkaline) batteries. Monocrystalline cells have a spectral sensitivity range from 300 nm (nearultraviolet) to 1100 nm (near-infrared), which includes visible light (400 to 700 nm). Due to this wide spectral range, they can be used in indoor and outdoor applications. Monocrystalline or singlecrystalline material does not contain impurities and, as such, the power conversion efficiency does not degrade over operating time. With a cell-efficiency of 17% to 20%, a solar chip provides the ability to extend run time, even in lowlight conditions, and increase battery life and run time on a small footprint—which can easily be accommodated in the design of portable products. Conventional rechargeable batteries can take several hours to recharge. Using a solar cell, the battery can be continuously trickle charged while under a light source. Low efficiency currently dictates the need for PV cells that harvest energy under a variety of lighting conditions; therefore, an engineer’s best bet is to use PV cells that respond to low-light levels. Large-scale grid integrations have made PV cells cheaper (economies of scale). Furthermore, cheaper raw materials and improved manufacturing processes are constantly pushing down prices for PV cells and panels. Engineers have sought to package solar cells right into the device in an unobtrusive way (either placed under a device’s display or cover). This integrated design would allow the mobile device to be charged from daylight without having a separate solar panel that needs to be plugged into it. Electricity generated from the cells would be fed to the device’s recharge-

Datapaq has introduced three new products for PV cell and module manufacturers. Datapaq designed the innovative SolarPaq systems to provide temperature-profiling solutions for the contact firing, anti-reflective coating, and lamination processes. These operations are all key to the quality and performance of the final PV cell and module. The SolarPaq system travels through the furnace or thermal process, measuring a time temperature profile directly from the product. The SolarPaq Anti-reflective Coating System provides temperature profiles from the solar cells as they pass through the silver nitride coating process. This is typically conducted using a plasma sputtering process and users can, now for the first time, monitor the cell temperature profile even with the plasma energized. Incorporating feedback from process engineers using the Datapaq profiling system in contact firing furnaces, the SolarPaq Contact Firing Cell Clamp is paired with custom-designed thermocouple probes to ensure accurate and repeatable measurements-the foundation for any process optimization. The SolarPaq Vacuum Lamination System is used to profile the final assembly stage of the solar modules. An all-new thermal barrier ensures that the data logger is protected from not only the heat of the lamination process, but also the external pressure that is applied.

Thompson Technology Industries (TTi) has developed a new generation of the Sunseeker Single Axis tracker. This new generation allows for increased height of the system and mounting on uneven surfaces while saving 10% to 15% on installation and maintenance costs. This tracker breaks TTi’s previous standards in the industry with the ability to drive even more panels in a slightly increased “footprint” over the previous generation. Output is increased without sacrificing energy production. With even fewer motors, operation and maintenance are lower and the tracker does not require field welding for installation. Savings are realized by the option to pile drive the support posts, which are less expensive and quicker to install. The tracker now has the advantage that allows it to increase the height to 78" and still meet a wind speed of 90mph with the panels at 45°. The tracker delivers faster installation than traditional cement foundations and I-beams now come standard with purchase and are priced into the tracker system cost.

Schenk Vision is a total-solution provider of metrology systems for PV thin-film modules worldwide. “Indirect metrology tests” such as, the measurement of pinhole density, layer thickness, or haze monitoring, enables manufacturers to evaluate the module quality of a solar panel and gives an early warning as soon as a process step no longer meets the preset tolerances. Yet, these indirect measurements alone cannot make a prediction about the final electrical efficiency of a solar panel. As today’s sun simulators or flashers are installed only at the very end of the production line, when low-quality modules have already gone through expensive back-end processing. Schenk has developed a unique innovation that is complimentary to flashers but enables an early feedback on the module efficiency. With the I-V Curve Tracer, a brand new measurement innovation, customers can evaluate and correlate metrology data from optical and electrical measurements along the line, and perceive an early feedback and a comprehensive overview of the entire manufacturing process. This global evaluation, uniquely offered by Schenk, reveals the real potential for process optimization.

PV design software tool Solmetric Corporation has released the Solmetric PV Designer, a software tool that enables solar PV designers to optimize module layout and energy production in a partially shaded environment. The software processes shade measurements from the Solmetric SunEye, a handheld electronic instrument, and enables module by module shade calculations even if only the corners of the array or roof are measured. It then calculates hourly AC kWh production. In addition, the software estimates the improvements in production by implementing SolarMagic power optimizers from National Semiconductor. PV Designer uses shade data collected for the installation site and enables the solar system designer to experiment with different array configurations to find the optimal design. The tool incorporates an extensive database of modules and inverters with complete specifications including dimensions. Designers can visualize shade and insolation over the array or roof area and compare different hardware, different module layouts, and with and without SolarMagic power optimizers. Calculations are based on the string current-voltage (IV) characteristics including the effects of partial shading. The system estimates the resultant energy production, and up to four design scenarios can be compared side by side. Solmetric Corporation | www.solmetric.com

Hedging with Derivatives in Today’s Environment By Brian Harms & John Leonti
R
enewable energy related companies often employ hedging strategies using financial instruments, such as derivatives, to attempt to mitigate certain market risks. For example, end-users may seek to mitigate interest rate risk in connection with a financing or market price, or basis risk in connection with the generation of energy at a wind farm. The use of derivatives to mitigate adverse movements in the relevant market is not an easy task. This is especially true in today’s tight credit market and uncertain regulatory environment. As end-users seek to hedge market risk with derivatives, they must carefully consider the other risks presented by these transactions. End-users should consider: 1) credit risk; 2) regulatory risk; and, 3) operational risk [despite whether a derivatives transaction is an exchange-traded transaction or over-the-counter (OTC) transaction].
Credit risk
Credit risk in the derivatives context generally comes in two flavors: a counterparty’s credit exposure to the other counterparty, and the end-user placing its own credit at risk. Consequently, end-users need to have effective assessment and monitoring procedures in place to properly assess credit risk and protect against it. Unlike exchange-traded derivatives transactions where the exchange itself acts as the counterparty to the trade, OTC derivatives transactions are privately negotiated bilateral transactions between counterparties that are typically documented on the International Swaps and Derivatives Association Master Agreement. Without an intermediary or clearinghouse between the parties, each party has to review the other party’s creditworthiness and the risk of deteriorating credit. In a typical hedging arrangement, the parties will agree on credit support terms. These terms are set forth in a credit support annex and incorporated into a master agreement. For example, a counterparty may agree to post cash or letters of credit with its counterparty when the exposure a counterparty has to the market reaches a specified threshold amount. The threshold amount refers to the amount of unsecured exposure one counterparty is willing to accept with respect to the other counterparty before it will require credit support. Presumably, when entering into these terms, each of the counterparties is comfortable with the risk profile of the other (or else they would require upfront credit support). If a counterparty’s risk profile adversely changes during the trading relationship, the other counterparty will likely require additional credit support. To address this concern, many hedging arrangements provide for the reduction of the threshold amount and an increase in collateral requirements upon the degradation of the credit quality of a counterparty. To illustrate, the threshold amounts in the credit support annex may be linked to debt credit ratings. If a counterparty’s credit rating is downgraded (e.g., to A from A), the counterparty’s threshold amount would decrease (and its collateral requirements would effectively increase). This construct has flaws. If a counterparty experiences rapid financial decline, the other counterparty may find its counterparty bankrupt or insolvent by the time a ratings agency downgrades the counterparty’s credit rating (e.g., Lehman). A somewhat more flexible version of the credit clauses are referred to as adequate assurance clauses. These clauses allow a counterparty to seek additional collateral if those requesting have reasonable grounds to believe their counterparty’s creditworthiness or performance is unsatisfactory. Although less stringent than the credit rating downgrade clause, a counterparty must be able to reasonably demonstrate its basis for the additional credit support under an adequate assurance clause, which likely requires some objective facts to support the request. Experience shows adequate assurance requests will be ignored, rejected, and refused as much as possible. In a volatile market, adequate means to reduce exposure to a counterparty is paramount. For instance, an end-user may be comfortable with a $50 million exposure to a financial institution at the outset of a trading relationship. But what if the exposure with respect to transaction between the parties doubles or triples rapidly as result of price movement in the underlying asset? Did the end-user negotiate the appropriate thresholds? Are the thresholds too high? Does the end-user now have to consider hedging the counterparty risk? What risks are now introduced? Documentation cannot replace diligence. End-users must continuously assess their counterparty’s creditworthiness.
As an alternative to OTC derivatives products, an end-user might be able to hedge its risk with the use of exchange-traded derivatives products. Although the use of exchangetraded futures products mitigates counterparty credit risk, these products are non-negotiated contracts with limited terms and introduce additional costs—as well as margin risk, since exchange trading requires participants to provide initial margin to open a (buy or sell) position and to maintain a minimum amount of margin until the position is closed. In the event of an untimely decrease in the value of an end-user’ account that results in a margin call by an exchange or broker, an end-user could find themselves short on cash or, if the position had to be closed-out because the end-user could not meet the margin call, taking a loss (and losing its hedge position).

On August 17th, 2009, the CFTC asked for public comment to consider whether the Carbon Financial Instrument (CFI) contract traded on the Chicago Climate Exchange performs as a significant price discovery contract. If the CFTC classifies the CFI contract as a significant Regulatory risk price discovery contract, the CFTC would gain additional oversight authority over the CFI Regulatory risk involves the risk related to how new laws, rules, and regulations will treat contract, subjecting the CFI contract and market participants to, among other things, the the derivatives market. The derivatives market has been under increased scrutiny.

Exactly how this plays out is left to be to seen, but the legislation to date has certainly raised questions and concerns among derivatives market participants. What is meant by “standardized” derivatives contract? Will vancouver convention centre, canada end-users be required to clear some or all of their trades? What type of reporting and registration requirements will be required? Although new laws and regulations may not affect the enforceability of a derivatives contract, they could cause unintended consequences that frustrate each of the counterparties’ intent. Those in the renewable energy space are all too familiar with this type of risk. Participants in renewable portfolio standard (RPS) compliance programs frequently express concern that changes in law regarding the RPS program could adversely impact their renewable energy credit (REC) agreements. RPS participants, therefore, seek to allocate change-in-law risk under REC agreements.

Operational risk
Derivatives are a highly complex part of the finance world and, therefore, end-users need to have personnel with specialized skills that can understand and value derivatives and their associated risks. However, for varying reasons some end-users use derivatives without skilled personnel and, in some instances, look to their counterparties for guidance. This is a recipe for disaster. Notwithstanding the inherent conflicts that exist between counterparties, a counterparty is not likely to understand the end-user’s specific risks and needs. End-users that do not have a welltrained team will be unable to appropriately assess credit or regulatory risk, and may find themselves at the wrong end of a trade. In today’s environment, a successful hedging strategy requires end-users to continuously review and assess credit, regulatory, and operational risks associated with their derivatives trades.

Wind Energy and the Canadian Commercial Bank By Thomas J Timmins
T
here has yet to be a Canadian commercial bank directly involved in wind energy development. This is not surprising. Canada’s banks observe some of the most conservative lending guidelines in the world. That said, having avoided the worst of the sub-prime credit crisis, which undid so many of their competitors to the south, Canada’s gigantic commercial banks are on the move once again, looking for assets to lend against. Wind energy is proven, reliable, and growing. Furthermore, across Canada, provincial governments have acted almost unanimously to remove regulatory hurdles and establish attractive state-backed, power off-take pricing arrangements. The combination of reliable revenue streams, friendly regulatory environs, rapid industry growth, and the continuing maturation of the sector means that Canada’s commercial banks will, eventually, develop an appetite for the sector.

Commercial banks function efficiently in industry settings where credit analysis, due diligence processes, and collateral documentation can be systematized and, to a greater or lesser extent, commoditized. In wind energy, financing opportunities obviously arise long before the actual construction or operation of a wind farm. A bank could, in theory, acquire a security interest in land option rights, land lease interests, and even easement interests. It could even take an interest in met-tower equipment, met-data, development plans, and several other early stage wind development assets. This type of development lending would provide much-needed early stage growth financing, but it is unlikely at this juncture. In light of their risk tolerance appetites and the need to reduce transaction costs through credit process and documentation process standardization, Canada’s commercial banks are most likely to enter the wind market as “take-out” lenders rather than as development financiers. In other words, Canada’s commercial banks will need to get used to financing already built developments before they can even contemplate project development finance. Wind is a relatively new industry in North America and, as any experienced developer w would attest, project risks remain high throughout each of the development stages of a wind energy project—even after a power purchase agreement is in place and construction contracts have been awarded.
reports; legal reviews of all land title matters, power purchase arrangements, product warranties, operating and maintenance contracts, provincial and municipal agreements, laws, bylaws, and regulations; and, independent valuation appraisals of the land interests held and the equipment owned by the project developer. What it means
Wind energy is ready for commercial bank financing and it can be expected that Canadian commercial banks will enter this sector in the near future as take-out lenders first, with project development financing to follow sometime later. Industry participants should expect Canadian commercial bankers to follow traditions and protocols similar to those they have utilized for a half-century or more in commercial real estate finance and real estate development finance. As such, in order to keep financing options open, it would be a good idea for project developers to assume they may one day be sitting in front of a bank lender, to make sure that land title interests are properly documented and fully assignable, to ensure that personal property interests are assignable and will remain so after construction, and to begin early to develop a financing package that will stand up to independent legal and consultant review. In other words, industry participants should expect commercial bank style financing commitments and security packages and plan for them. The entry of Canada’s large commercial banks into the wind energy sector will bring about exciting changes to the industry. It will catalyze industry competition, lead to the evolution of development standards, sponsor credit modelling and assessment norms, drive resource assessment industry best practices, put downward pressure legal documentation costs, normalize capital pricing, and even impact the development of post-warranty operation and maintenance services and project insurance facilities. The result will be better access to capital, more standardized industry practices, more predictable development and operation costs and, generally, a better environment for both lenders and borrowers. Put succinctly, the power of Canada’s vast commercial bank to impact the development of the North American wind energy industry sector cannot be overstated. Thomas J Timmins is chair of the Wind Energy Law Practice Group at the Canadian law firm Dale & Lessmann LLP. Timmins acts regularly on behalf of wind developers, wind industry suppliers, project development financiers, and take-out debt lenders in Canada, and has participated in the development of several of Canada’s largest wind Dale & Lessmann LLP | www.dalelessmann.com
How to enter: advancing credit to a project
As with any financing, numerous assurances will be required before a lender can advance funds. As commercial lending to the wind industry develops, one can expect to see standardized commercial bank lending documentation evolve to require the following items as a matter of course: the assignment of the developer’s interest in the relevant power purchase agreement, operation and maintenance contracts, land rights agreements, attributable carbon credits, equipment interests, licenses, permits and insurance policies; the establishment of notice requirements regarding material changes, non-compliance with environmental laws, changes of ownership, and third party defaults; the provision of personal and/or related company guarantees; comprehensive environmental assurances; and, of course, restrictive undertakings with regard to further borrowing. In addition to the representations, warranties, covenants, and assignment that will be required, commercial bank lenders will also develop standardized due diligence protocols including: independent expert reviews of wind data and environmental

geothermal energy
How Heating, Cooling & Electricity are Produced by Geothermal Energy
T
he term “geothermal” is derived from the Greek words for earth (“geo”) and heat (“therme”). In essence, geothermal energy is power harnessed from the earth itself. Heat from the earth’s core, which averages about 6,650 degrees Fahrenheit, emanates out toward the planet’s surface. Heated springs and geysers up to three miles underground can be accessed by special wells that bring the hot water (or steam from it) up to the surface, where it can be used directly for heat or indirectly to generate electricity by powering rotating turbines. Since the water under the earth’s surface is constantly replenished, and the earth’s core will continue to generate heat indefinitely, geothermal power is ultimately clean and renewable. Today, there are three main methods for harvesting utility grade geothermal energy: dry steam, flash steam, and binary cycle. The dry steam process brings steam up directly from below to drive turbines that power electricity generators. Flash steam plants bring the hot water itself up from below; it is then sprayed into a tank to create steam to drive the turbines. These two methods are the most common, generating hundreds of megawatts of electricity across the American West, Europe, and elsewhere. But expansion is limited as these plants only work in tectonic regions where it is easier to access ground heated water. The binary cycle technology extracts close-to-the surface warm (not necessarily hot) water and combines it with a second (“binary”) fluid, like butane or pentane, which has a low boiling point. This fluid is then pumped through a heat exchanger, where it is vaporized and sent through a turbine before being recycled back into the system. Binary cycle geothermal plants already pump out dozens of megawatts of electricity in California, Nevada, and Hawaii, among other places.
But geothermal isn’t just for utilities. Homeowners looking to go green and lower their utility bills can install a residential system, essentially a scaled-down version of the binary cycle system. A series of pipes is installed underground. Water circulating in the loop is heated naturally underground and then transferred to a heat exchanger, which concentrate the energy and releases it inside the home as heat. In summer and in warmer climates, the process is reversed to fill the home with geothermal-cooled air. Geothermal has its drawbacks. For homeowners, it may be hard to justify the upfront expense of $7,500 or more to install a system, though the IRS now offers tax credits for 30% of the cost. At the utility level, geothermal plants are costly to build and operate. And, finding a suitable site requires digging expensive test wells with no guarantee of hitting a productive underground hot spot. Nevertheless, analysts expect utility grade geothermal capacity to nearly double over the next six years. The Obama administration has set aside $750 million for geothermal development, and Congress has also been generous, allocating $129 million to the Department of Energy for various geothermal programs. Geothermal may be in its infancy in the US, but it is a big player in Iceland, which derives 26.5% of its electricity needs from geothermal, and in New Zealand, which gets 10% of its electricity likewise.

Recovery Act Investments Geothermal energy gains $338 million Geothermal Resources Council (GRC) leadership lauded Department of Energy Secretary Steven Chu’s October 29th announcement that $338 million of American Reinvestment and Recovery Act grants had been awarded to support geothermal research, development, demonstration, and deployment in more than 40 states. “This is an unprecedented federal investment in geothermal energy,” said Dr Curt Robinson, GRC’s executive director. “Finally, this source of clean, renewable, base-load energy will be developed and utilized. The $338 million represents a major commitment by the federal government to get this source of energy contributing to the grid.” States receiving large federal grants included Nevada ($93 million), Oregon ($39 million), California ($27 million), and Colorado ($18 million). Several companies scored big with the federal grants: AltaRock ($26.4 million), TGP Development Company ($14 million), Ormat Nevada ($13.7), Naknek Electric Association ($12.3 million), and GE ($10.9). Public groups that received support include: Geological Surveys from 40 states ($17.7 million), Lawrence Berkeley National Laboratory ($7 million), El Paso County ($5 million), and the Colorado Department of Personnel and Administration ($4.6 million)
Funds will also go to some of the nation’s most innovative universities: Southern Methodist University ($5.2 million), Ball State University ($5 million), Utah State University ($4.6 million), University of Alaska ($4.6 million), University of Utah ($2.8 million), the University of Kansas ($2.4 million), and the University of Nevada ($2.2 million). Research will take place in several areas of interest: innovative exploration and drilling projects; coproduced, geo-pressured, and low-temperature projects; enhanced geothermal systems (EGS); EGS components research, development, and analysis; geothermal data development, collection, and maintenance; and geothermal heat pump demonstration projects. “Geothermal energy is a clean, constant, reliable, dependable, and safe source of energy,” Robinson concluded.

An Economically Sustainable Future Alaska’s innovative geothermal project could fuel the region By Laura Tanis | Photos courtesy of the City of Akutan (www.aleutianseast.org)
A
geophysical survey team is using electro-magnetic probes in the remote community of Akutan, Alaska to help investigate the potential of the nearby geothermal resource. If a significant resource is identified, this would potentially allow the Eastern Aleutian region to realize a clean, inexpensive, and reliable source of energy. Currently, the city of Akutan (Akutan is located on Akutan Island in the eastern Aleutians, off the southwest tip of the Alaska Peninsula, between the Bering Sea and the north Pacific Ocean. Population: 713) and Trident Seafoods, a large plant that operates within the community, use a combined peak of 7 MW of diesel-
generated power. The city’s power cost exceeds $0.32 per kWh. Development of power from the Akutan geothermal project would eliminate the dependence on diesel fuel, reduce carbon emissions, and promote economic and cultural sustainability of Akutan and the region. Geothermal energy is an environmentally friendly source of renewable energy that harnesses the natural power of steam from the earth to generate electricity and heat while producing almost no greenhouse emissions. This cost-effective energy source is located right in Akutan’s backyard. The only question is whether it is economically feasible to develop the geothermal energy. The geophysical survey is using electro-magnetic probes to detect subsurface electrical patterns, which will be studied to help locate the geothermal reservoir. The technical team established a base camp in Hot Springs Bay Valley on Akutan Island. Team members will conduct testing of as many as 50 locations. “We are working closely with the Akutan Village Corporation, the Akutan Traditional Tribal Council, the Aleut Corporation, Trident Seafoods, and our residents to develop a geothermal power and heating resource to replace our dependence on diesel fuel,” said city Mayor Joe Bereskin. “It’s an exciting, long-term project,

with the University of Alaska Fairbanks, industry experts from the geothermal industry, and state/federal agencies for the well testing and long-term monitoring program. “Preliminary results from this summer’s fieldwork are extremely interesting,” said Dr Amanda Kolker, project manager for the Akutan Geothermal Project. “We are rapidly developing a better understanding of the geothermal resource on Akutan. By the end of the year, we should have a good conceptual model of the resource, which will help in targeting successful geothermal wells.” Aleutians East Borough | www.aleutianseast.org
which will translate into jobs and economic activity for the community and the region.” Exploratory activities began in May of 2009 with a soil chemistry survey of the Akutan geothermal area. In June and July of 2009, a remote sensing study was conducted by researchers at the University of Alaska Fairbanks, using thermal information from satellite images to detect thermal anomalies in the Akutan geothermal area. The geophysical survey in progress, using electro-magnetic techniques, will aid in detecting subsurface resistivity/conductivity anomalies. Combined, these three surveys (all of which take place on the surface and require no drilling) will help locate the geothermal resource on Akutan. Currently, the city is funding this project with an $800,000 loan from the Alaska Industrial Development and Export Authority, which will carry the project through until the end of the year. The city of Akutan was recently awarded a grant from the Alaska Renewable Energy Fund. Those funds are expected to be available within the next three months. The remainder of the $2.59 million in Alaska Energy Authority grant funding will go toward the drilling of geothermal wells. As a necessary supplement to this funding, Akutan recently applied for $4.5 million in Department of Energy stimulus grant funds for next year’s drilling program. Akutan also plans to request additional state funding later this year. Surface exploratory activities are scheduled to continue throughout summer and fall of 2009, with exploratory drilling scheduled for the summer of 2010. The drilling phase of the project will employ a heliportable coring drill rig to drill four “slim holes” up to 1500 feet deep in areas selected on the basis of the 2009 resource evaluation. Once wells are complete, the city plans to team up

HydroPower: “An incredible opportunity”
T
$531 million in Clean Renewable Energy Bonds Hydroelectric projects received about 24% of the $2.2 billion in Clean Renewable Energy Bonds allocated recently to renewable energy developers, according to the National Hydropower Association. “By providing more than $531 million in funding for hydropower projects, the federal government is supporting efforts that will create jobs and add to the country’s domestic, affordable electricity generation resources,” said Jeffrey Leahey, NHA’s senior manager of government and legal affairs. The US Treasury Department allocated the bonds to more than 800 companies and cooperatives nationwide. The funding was authorized by the Energy Improvement and Extension Act of 2008 and the American Recovery and Reinvestment Act of 2009. In the past, the federal bonds program often overlooked promising hydroelectric projects. The latest allocation was based on a pro rata basis, a change the NHA had been pushing for. “NHA salutes the legislators and policymakers who have improved the CREBs program, so that it recognizes the extraordinary energy, environmental, and economic benefits that can come from hydropower,” said Leahey. The CREBs program is designed to help renewable energy developers access lower-cost credit for renewable energy projects. The bonds are tax-credit bonds, which means the company does not pay full interest. Instead, the federal government provides the company a tax credit covering 70% of the interest earned.
he US hydropower industry is ready to lead the country in the creation of 700,000 family supporting jobs by 2025 as it helps steer the United States toward energy security and a clean, renewable energy future. Hydropower can add 60,000 MW of clean, renewable energy to the nation’s electric grid by 2025. That’s enough to serve 17 million households— the equivalent of all the homes in New York City, Los Angeles, and Chicago combined. The findings prompted Pennsylvania Governor Edward Rendell to call on policymakers to support development of hydropower, America’s largest renewable energy resource. “It’s time to invest in renewable energy resources that generate electricity in this country and that provide jobs for Americans. Hydropower presents elected officials across the country an opportunity to bring thousands of long-term, family wage jobs to our states.” Voith Hydro CEO Mark Garner agreed. “This study confirms what our experience at Voith Hydro has already shown—investments in hydropower lead directly to good-paying, long-lasting American jobs. We have seen 27% growth in permanent employees in the past two years and, as the hydropower industry continues to grow, we have a huge potential to create additional clean, family wage jobs across the United States.” The US hydropower industry today has 100,000 MW of installed capacity. The industry will add 60,000 MW of new capacity through new technologies, efficiency improvements, and research and development. “The hydropower industry is prepared to double its current capacity of clean, domestic, renewable waterpower resources,” said NHA President Andrew Munro of Grant County (WA) Public Utility District. “Hydropower offers tremendous potential for America to double is renewable energy production, provide reliable electricity for American families, and create thousands of new jobs.” The US hydropower industry currently employs approximately 300,000 people. As the industry continues to grow, every region will see additional good jobs and new economic opportunities. According to James Lautar, international representative for the International Association of Machinists and Aerospace Workers, “Hydropower is already an important source of goodpaying, high-quality jobs for workers across the country. A national investment in hydropower will help grow American jobs for decades to come.” In addition to providing clean, affordable, domestic electricity, hydropower also helps foster the growth of other renewable energy resources. By providing load firming and energy storage, hydropower helps maximize the benefits of solar and wind resources, too. In fact, at a recent green jobs event in Pennsylvania, Energy Secretary Steven Chu called hydropower’s dual roles “an incredible opportunity” to expand the country’s clean energy resources. “As Secretary Chu points out, both hydropower and pumped storage serve the country in many different ways. Current hydropower capacity alone helps us avoid 225 million metric tons of carbon dioxide emissions annually, so the contributions are significant,” said NHA Executive Director Linda Church Ciocci. Church Ciocci echoed Governor Rendell and union representatives, stating that NHA is calling on Congressional leaders to: • Enact a national RES that recognizes and supports hydropower; • Support long-term tax incentives that give hydro parity with other renewable; • Accelerate licensing for pumped storage and small hydro; and • Expand federal R&D funding for hydropower technologies “Hydropower must play a critical role in our national energy, environmental, and economic policy,” Church Ciocci said.

Roadmap to the Commercialization of Next Generation Biofuels By Mark Warner, P.E.
F
irst generation ethanol and biodiesel production in the US expanded significantly during the period of 2000 to 2008, with ethanol production capacity tripling according to the Renewable Fuels Association. This dramatic growth of production capacity was possible as the projects met some of the key criteria for rapid commercialization: their technology was well-known with a proven operating history, vendors were able to provide a turnkey plant with a performance guarantee, and the project development process was something banks and investors were accustomed to financing. All of these factors led to projects that traditional financing institutions were comfortable funding. By contrast, the factors that allowed first generation renewable fuels to grow at a historic rate have limited the commercialization of next generation technologies. Many second generation technologies have been operated at pilot scale, not commercial scale. There are no vendors that can provide a commercial scale technology with a performance guarantee adequate to get standard commercial financing. A major limiting factor for the second generation biofuel processes comes from the fact that their capital construction cost is significantly higher than the first generation projects. Traditional corn based ethanol plants typically have a capital construction cost of around $1.5 to $2 per gallon of annual capacity (a 100,000,000 gallon per year plant would cost between $150 to $200 million dollars). Cellulosic ethanol facilities are generally projected with a capital construction cost of $5 to $10 per gallon of annual capacity. This represents roughly a five-fold increase in capital cost for facilities that do not have a proven operating history. Engineering for large capital projects has developed into a standardized process that is expected by most traditional financial institutions and includes a feasibility study, project scoping, detailed design, procurement, construction, start-up, and performance testing. The purpose of this process it to define scope and cost as early as possible, before significant amounts of capital are committed. Each of these processes is detailed as follows… Feasibility study: An early phase study that vets a business model under a given set of assumptions, identifies major risk, and helps management or investors decide if the project is worth investing in. Project scoping: Often referred to in the industry as front-end loading (FEL) or front-end engineering design (FEED), this phase of the project takes the feasibility study and expands the detail to a specific site. It defines the key process equipment, utilities, infrastructure (roads, docks, rail, etc.), and other major factors of the project. Detailed design: This phase of the project is where the scoping documents are refined to a point where a contractor can construct the facility. The work product at the end of detailed design is a set of specifications and construction drawings that are of sufficient detail for a contractor to supply a fixed price bid and construct the facility. Procurement: Key engineered equipment must be specified and purchased early in the process to allow the detailed design to be completed. Items such as gasifiers, reactors, distillation towers, heat exchanger, large tanks, distributed control systems, and other items that are not “off the shelf” items are part of this procurement cycle. Construction: Upon completion of the detailed design, a construction contractor can be selected. On large-scale projects it is common to use a general contractor who will be responsible for the overall project, even though their company may sub-contract major portions of the work. Start-up: At the point when a project is mechanically complete, responsibility is passed to the start-up crew. Initial efforts are called commissioning, where equip-
ment is often tested with water and inert gasses to make sure basic functions are confirmed (pumps are able to pump, tanks do not leak, boilers produce steam, etc.), and instruments are calibrated. Once each of the systems has been commissioned, raw materials will be introduced and the plant begins operation. Performance testing: A formalized, third party administered performance test is generally required by financial institutions to confirm the key operating parameters within the pro-forma that justified the project. These parameters include demonstration of plant production capacity, along with usage of key raw materials, and utilities. This test is normally run for a seven-day period and is overseen by an independent engineering firm. The source of project funding will typically impact the contracting style that is utilized for a project. The three main contracting formats are: cost-reimbursable, fixed-price, and engineer-procure-construct (EPC) with a performance guarantee. Each of these is detailed as follows… Cost-reimbursable: Often referred to as time and materials, the cost is defined by hourly labor rates, a mark-up percentage on equipment and sub-contracts, and a contractor fee. This approach is usually best for projects that are not fully defined at the point of starting construction and when schedule is the driver. Fixed-price: When engineering is complete and the project schedule allows, multiple contractors can bid on a project to be completed under a fixed-price for the scope of project outlined. This is generally the favored approach for projects where the technology is proven, the design is set, and major changes during construction are not anticipated. EPC with a performance guarantee: This is a turn-key project where the owner is purchasing a fully operable facility for a fixed-price. The contractor will be responsible for all phases of the project process, from detailed design through performance testing including guaranteeing that the project passes its performance test. The primary differences between these contracting mechanisms are the risks and who accepts them. In general, the performance guarantee is seen as a larger risk than the cost of construction guarantees, and not typically available for emerging technologies. Companies that provide the underlying production process for traditional industries, such as corn based ethanol (called the “process provider”), have not yet materialized for cellulosic ethanol and algal based biofuels. This does not imply a lack of companies with second generation technologies; they are just not demonstrated at a significant enough scale for financial institutions to have comfort with a performance guarantee. As neither contractors nor process providers are willing to accept the risk of a performance guarantee, EPC is not a viable option for emerging technologies. Cost reimbursable construction management is better suited to the fast-paced scheduling and ongoing design of second generation biofuels, but requires significant construction experience that many technology developers lack. There is a significant number of promising second generation biofuel technologies that have not been commercialized, partly due to a lack of available financing. The core of the financing issue is the lack of a technology guarantor and a project financing system that has become accustomed to EPC style project execution. Because EPC is not practical for emerging technologies, these projects will need to raise a higher amount of equity and possibly utilize the US DOE and/or USDA loan guarantee programs to bring their technologies to full commercial operation.

biopower products & news Wood waste recovery systems Rawlings Waste Wood Recovery Systems has completed one of the first wood waste recovery systems to introduce biomass as fuel-to-heat cement kilns at Mitsubishi Cement in Lucerne Valley California. The system is capable of processing and storing up to 350 tons of premium biomass fuel wood waste to be burned along with coal to reduce the amount of greenhouse emissions. The biomass will replace part of the annual tons of coal the plant would otherwise have used. The Rawlings Electric portable wood hog is a rugged, high-performance hog that can reduce various types and sizes of contaminated wood waste to biomass fuel. Once the wood waste has been processed through the hog, the metal is removed by an overhead self-cleaning magnet and then conveyed to a walking floor stoker storage system. To ensure the optimal size end product the wood waste is then processed over two vibrating finger screens, and then transferred to the kilns via a blower system. Rawlings Mfg has been manufacturing and installing the patented Rawlings Wood Hog and wood waste recycling systems for over 30 years. Both vertical and horizontal models are available in stationary, portable, and skid mounted systems. Rawlings Wood Hogs | www.wastewoodhogs.com
Proprietary production system for renewable fuel Joule Biotechnologies, Inc. recently unveiled its breakthrough HeliocultureT technology—a revolutionary process that harnesses sunlight to directly convert carbon dioxide (CO2) into SolarFuelT liquid energy. This eco-friendly, direct-to-fuel conversion requires no agricultural land or fresh water, and leverages a highly scalable system capable of producing more than 20,000 gallons of renewable ethanol or hydrocarbons per acre annually, far eclipsing productivity levels of current alternatives while rivaling the costs of fossil fuels. Joule’s transformative Helioculture process leverages highly engineered photosynthetic organisms to catalyze the conversion of sunlight and CO2 to usable transportation fuels and chemicals. The scalable SolarConverterT system facilitates the entire process—from sunlight capture to product conversion and separation—with minimal resources and polishing operations. This represents a significant advantage over biomass-derived biofuels including newer algae- and cellulose-based forms, which are hindered by varying obstacles: costly biomass production, numerous processing steps, substantial scale-up risk, and capital costs. The modular SolarConverter design is engineered to meet demand on a global scale while requiring just a fraction of the land needed for biomass-based approaches. It can be easily customized depending on land size, CO2 availability and desired output. The functionality is proven and can readily scale from smaller operations with limited land to extensive commercial plants. Joule Biotechnologies | www.joulebio.com

Biomass-to-power system Cyclone Power Technologies Inc. and Robotic Technology Inc. have entered into a teaming agreement to advance the development and commercialization of Cyclone’s vegetative biomass-to-power engine system as it can be applied to advanced robotic platforms. Cyclone’s prototype biomassto-power generator is a self-contained, compact system that utilizes the company’s award-winning waste heat engine (WHE) to produce power from plant-based biomass combustion. RTI is currently developing the Energetically Autonomous Tactical Robot (EATR) under a Phase II SBIR project sponsored by the Defense Advanced Research Projects Agency (DARPA) that will locate, harvest, and process for the engine suitable vegetation in the environment to accomplish a variety of military missions without the need for manual or conventional refueling. At the heart of Cyclone’s current biomass-to-power system for the proof-ofconcept EATR is the patent pending WHE, a six-cylinder Rankine cycle external heat engine capable of generating up to 15HP of mechanical power. An attached vegetative biomass combustion chamber produces up to 600°F of heat to run the WHE at peak performance. An alternator or generator then converts mechanical energy from the engine into as much as 10kW of usable electricity. The entire system including engine, heat exchangers, burner, electrical alternator/generator, and fuel hopper is mounted on a pallet for portability. A higher horsepower, more compact version of the engine system is planned for the Phase III Commercialization of the EATR, to be placed within a prototype EATR vehicle.

In Search of Tomorrowâ&#x20AC;&#x2122;s Biofuels
O
nce seen as the solution for climate change, biofuels have since come under attack because of the use of fertile land to grow core biofuel crops. Now British teams are developing biofuels that really could help save the planet. The British Biotechnology and Biological Sciences Research Council (BBSRC) is administering the largest ever UK public investment in bio-energy research. The money is being shared between six groups of researchers throughout Britain who are working on different aspects of the problem to develop the next generation of biofuels. Alf Game, science manager and deputy director of research, innovation, and skills at the BBSRC, is the pivot around whom the development of the program has revolved. â&#x20AC;&#x153;Iâ&#x20AC;&#x2122;m not a good research scientist,â&#x20AC;? he admits. â&#x20AC;&#x153;Never was.â&#x20AC;? Instead, Game has made a career of enabling the research of others, working for one scientific administrative body after another. And, itâ&#x20AC;&#x2122;s no different this time. â&#x20AC;&#x153;The Sustainable Bio Energy Centre is a virtual centre of six teams led from five different universities and institutes that are working on different aspects of the problem,â&#x20AC;? he says. â&#x20AC;&#x153;Itâ&#x20AC;&#x2122;s not like a pipeline, where each of the teams feeds into the next; what we have are exemplars, models or patterns to be copied, of what can be done at different stages of the pipeline.â&#x20AC;? Gameâ&#x20AC;&#x2122;s job has been to lead the conception and construction of the centre so that it keeps developing toward the future. The first generation of biofuels was relatively easy to produce. Plants produce their own concentrated stores of energy in seeds or tubers, and biofuels simply tapped into those, taking oils from seeds and ethanol from the sugars in tubers. But such crops compete directly with food for agricultural resources and, after the initial enthusiasm, it became clear that the quantities of fuel needed to make a difference would make serious inroads into food security. Now scientists are looking at the entire plant as a source of biofuels. â&#x20AC;&#x153;The next generation will either use by-products, like wheat straw,â&#x20AC;? says Game, â&#x20AC;&#x153;or it will be grown where it wonâ&#x20AC;&#x2122;t compete with food. And, that doesnâ&#x20AC;&#x2122;t have to be landâ&#x20AC;&#x201D;one of the most promising sources is algae.â&#x20AC;?

Thereâ&#x20AC;&#x2122;s plenty of material available: waste from agriculture or the food-processing industry, bracken, various grasses, coppiced willow, or poplar trees. â&#x20AC;&#x153;A main interest of the research is to find useful ways to break down lignins and cellulose,â&#x20AC;? Game explains. Cows and termites already do it, but they have complicated digestive systems with lots of different microbes. There is an insect, though, that is attracting special attention. â&#x20AC;&#x153;A tiny marine wood-boring crustacean called the gribble has a sterile gut and employs very few enzymes to digest the lignins,â&#x20AC;? says Game. â&#x20AC;&#x153;One of our projects is to see if we can understand how these work, to replicate this in industrial processing.â&#x20AC;? Other projects are working on improving biomass crops, breaking down the materials and turning them into usable fuels. Altogether there are 15 universities and institutes and 15 industrial partners involved. There are also environmental engineers working on energy efficiency. â&#x20AC;&#x153;It doesnâ&#x20AC;&#x2122;t make sense to transport wood around the country to huge refineries,â&#x20AC;? Game points out, â&#x20AC;&#x153;so processing will have to be done near the source.â&#x20AC;? That will introduce a useful additional source of income to rural economies. â&#x20AC;&#x153;Biofuels wonâ&#x20AC;&#x2122;t totally replace petrochemicals,â&#x20AC;? Game admits, â&#x20AC;&#x153;but they could make a difference. There are estimates that between 10% and 20% of Britainâ&#x20AC;&#x2122;s fuel needs could be grown in Britain.â&#x20AC;? The role of Alf Game and his colleagues is to help the scientists work together to produce more than the sum of their individual efforts. â&#x20AC;&#x153;What I like about this job is that we can help scientists do better science,â&#x20AC;? he says. â&#x20AC;&#x153;We can add value to what they do and make a difference in a project that will make a difference in society.â&#x20AC;?

energy efficiency Knowing How to Measure a Green Building can Help Sell Renewable Energy By Paul Nutcher, CSI CDT | Photos courtesy of www.solarbrella.com
T
he renewable energy industry could benefit greatly by targeting green building projects. This is true for project teams setting up systems for distributed renewable energy generation on building sites, the manufacturers of the system components, and many other ancillary businesses with a stake in a building’s energy performance. Furthermore, if the diffusion of renewable energy technology has been slow to gain market traction, the LEED program could be a significant driving force for expediting the growth of BIPV and utility scale installations, as well as other renewable generation systems and energy storage systems. Commercial buildings in the United States consume 18% of the nation’s energy and are responsible for 18% of the nation’s carbon dioxide emissions, according to the Department of Energy. The residential building sector consumes 22% of electricity and contributes 20% of the carbon emissions, as reported during the Energy Programs Consortium presentation February 2008: “Income, Energy Efficiency and Emissions: The Critical Relationship.” With renewable energy providing less than 10% of the electricity in the US, the building sector of the economy has as much growth potential for renewable energy product manufacturers as the transportation and industrial sectors of the economy. A realization that buildings needed to become more energy efficient and healthier for their occupants, while reducing their impact on the environment, sparked the earliest stakeholders at the non-profit US Green Building Council (USGBC) to take steps toward addressing more sustainable buildings. The result of those first steps was a program to measure a building’s energy and environmental performance. Today, the most widely recognized national rating tool for third-party verification of a sustainably designed, built, operated, and maintained building is the LEED Green Building Rating System from the USGBC, which first introduced the first of its family of rating programs in 1999. Marketing to the green building industry will take effort from stakeholders in the renewable energy business because they will first need to understand how such energy systems can enhance a high-performance building project— which under the USGBC program results in “LEED certification.” A LEED score
LEED stands for Leadership in Energy and Environmental Design, and measures the environmental impacts and energy performance of buildings as two of its fundamental goals. The LEED family of green building rating systems contains sets of voluntary performance standards, many of which have become mandated by city and state governments, as well as most federal agencies. The Government Services Administration (GSA), possibly the world’s largest landlord overseeing courthouses, offices, agencies, among other federal buildings, requires a LEED Silver certification level. The LEED for New Construction v. 3.0 (LEED-NC) rating system is divided into five main categories including sustainable sites, water management, energy and atmosphere, and indoor environmental quality. There are also two other categories for exemplary performance including the Innovation in Design and Regional Environmental Priorities categories for capturing ways in which the building significantly out performs the benchmarks in the first five categories or addresses a regionally specific environmental issue (i.e. water conservation or diverting materials from landfills). On-site generation of electricity from the sun, wind, or other natural sources have the greatest opportunity for assisting building project teams within the Energy and Atmosphere Credit Category of LEED. Most points in the rating system assigned to any of the categories are in the Energy and Atmosphere category, with a possible one to 19 points for Optimizing Energy Performance, another seven points are possible for incrementally larger percentages of energy usage from renewables, and the project team can gain even more points toward LEED certification for purchasing green energy credits. Because may renewable energy systems measure the output of the energy system, other credits dealing with the commissioning and verification of a renewable energy sources can offer further LEED points. The amount of possible points in the Energy and Atmosphere category is significant because it only takes 40 points for certification. So, the LEED point totals typically shoot high up the scorecard when renewable energy equipment is installed on LEED buildings. Many gain LEED Silver, Gold, or Platinum certification levels. For reference, the highest LEED Platinum certification is between 80 to 100 points. 72

But there is still a catch. Before even considering going for LEED, there are prerequisites in all but the Water Management, Innovation in Design, and Regional Environmental Priorities categories. The important one here is the energy efficiency benchmark, ASHRAE 90.1-2007. Plus, the energy systems must be commissioned by a third party to verify the performance of the HVAC system and no CFCs are permitted in the cooling system. Once the prerequisites for the energy systems have been met, the higher the percentage of energy optimization the building is designed to achieve the more points it will gather. Should the building go beyond 40% energy efficiency above the benchmark, there is another point available in that sixth category: Innovation and Design, for example. Retrofitting renewables
LEED Green Building Rating System has separate programs for covering the two phases of a building’s lifecycle, one for new construction (Schools, Core and Shell, Retail, Homes, Neighborhoods, and there are more in development), and one for ongoing maintenance and operations of a building after the construction phase. The LEED for Existing Buildings Operation and Maintenance (LEED-EBOM) rating system follows a sustainably built structure to the end of its useful lifespan and the rating tool can be applied once the building has been occupied for at least a year. The point structure and categories are a bit different as the LEED-EBOM rating system is more focused on post-occupancy issues, such as efforts to reduce peak energy demand, save on utility bills, and reduce the carbon footprint of a building or real estate portfolio. Though teams constructing new buildings are the focus of the LEED-NC program, property managers, real estate portfolio owners, and other building industry practitioners looking for a larger return on investment after a renewable energy retrofit installation will decide whether to go for LEED-EBOM. The rationale for LEED-EBOM to this market segment is that properties certified by the USGBC stand out in annual performance reviews, annual budget planning sessions, and add a premium to leasable space. The LEED-EBOM certification process can also identify deficiencies in standard practices that need correction, and then provide the best steps toward operational improvements. An annual re-certification of LEED-EB status from the USGBC may extend the lifespan of a structure because the rating tool can help in the development of a system to avoid a decline in building maintenance. Renewables & LEED for existing buildings
Between one to 18 points are available in the Optimized Energy Efficiency Performance category in the LEED-EBOM rating program. During commissioning and energy audits, inefficient areas of the structures’ operations are pinpointed and monitoring of energy consumption on major mechanical systems is initiated and a program for ongoing monitoring begins. The number of points earned is contingent upon a facility’s EPA ENERGY STAR rating or the percentile level above the national median. LEED points are earned when increased levels of operating energy efficiency can be documented and, as a result, reduce the environmental impact of excessive energy use. A facilities manager can also purchase Green-e certificated energy (a similar option for project teams on new construction), to gain points for helping reduce greenhouse gases and by helping to develop a market for renewable energy. Points are also available for continued commissioning of the building performance. During this process, the building’s capabilities, advantages, and weaknesses are assessed by the commissioning agent so financial costs and benefits are calculated. Training programs are developed and building operating plans are updated. Using an ongoing commissioning program that reflects changes in an existing facility’s occupancy, usage, maintenance, and repair needs ensures adherence to stated revisions and upgrades. Periodic adjustments and reviews ensure optimal energy efficiency. The on-site and off-site generation of renewable energy can also gain from one to six points toward LEED-EBOM certification. It is up to the energy consultant to determine whether solar, wind, biomass, geothermal, and biogas technologies are the most advantageous.
Tracking greenhouse gas emissions Conserving through greener site development
The amount of radiant heat from the sun penetrating the building envelope and the thermal transfer properties of the hardscape can all impact the energy efficiency of a building. LEED programs recognize this strategy for overall reduction of energy usage on the property. The impact a rooftop solar array has on the performance of the building envelope is good to know when trying to sell a building owner on the systems. In fact, a tax credit from the Energy Policy Act of 2005 provides up to $1.80 per square foot for the developer, based on improvements to the building envelope and another 60 cents each for installing more energy efficiency for lighting and HVAC systems. Renewables can have an impact on gaining the tax credit by powering a portion of the energy needed for lights and conditioning the interior space. Other site credits with implications for the renewable energy product manufacturer include the designation of parking areas for plug-in electric hybrid cars, among other strategies for reducing carbon emissions from fossil fuels. Indirectly, less energy is needed when building project teams design and build for a reduced impact on the heat island effect. The rooftop configuration of a solar array can have a significant effect on how the thermal gradient differences in urban areas versus undeveloped areas will be addressed. Again, any assistance here from a renewable energy installation should be communicated to the building team prior to the pre-design phase of a construction project to improve the chances that the associated products and services will be specified in the construction documents. The future of LEED
The LEED rating system (or an equivalent rating tool; i.e. GreenGlobes, ICC 700) will one day become the standard that most governments set for project teams wanting a permit to build. Looking at the current building codes in most of the country, with the exception of governments that have already adopted LEED as the standard for getting a building permit and there are many already, some people may ask why we didn’t build like that all along? Much of the intent of the LEED credits are a throwback to the way the building industry was headed decades ago, but a mindset of unlimited energy and materials took over. LEED appears to be here to stay and not a moment too soon as the world gears up to address climate change. All of these efforts could help the long term prospects of renewable energy product manufacturers. Green Apple Group, LLC www.GreenAppleConsult.com
RSC Equipment Rental has launched an equipment emission tracking service that automatically calculates greenhouse gas and criteria pollutant emissions from diesel-powered equipment. The data regarding these emissions are critical for regulatory compliance, voluntary reporting, and carbon footprint reduction. RSC is the first company in the equipment rental industry to provide customers accurate and detailed emissions data. The data will change the way customers in the industrial, maintenance, and non-residential construction markets use rented equipment and help them become more sustainable. RSC took great lengths to ensure the integrity of the methodology for this tracking solution. The Global Institute of Sustainability at Arizona State University independently verified the methodology, the formulas, and the data collected. The verified formulas include the hours of use, load factor, fuel consumption, density conversion, emission factors, and engine horsepower/tier level. The service tracks the greenhouse gas emissions carbon dioxide, methane, and nitrous oxide, as well as emissions of other key criteria pollutants including nitrogen oxides, carbon monoxide, particular matter, and hydrocarbons. The formulas are applicable to diesel powered equipment with hour meters, which reflects 88% of RSC equipment with hour-metered engines. RSC Holdings Inc. | www.rscrental.com/sustainability
A New Tool for Combating Climate Change? Getting sued for greenhouse gas emissions By Sarah A.W. Fitts, Stuart Hammer & Harry Zirlin
A recent Court of Appeals decision is opening a new front in the battle to curb emissions of greenhouse gases (“GHGs”). To date, proponents of efforts to curb GHG emissions have focused on the potential passage of comprehensive climate change legislation by the US Congress and regulation of GHGs by the US Environmental Protection Agency (“EPA”). However, the recent decision raises the possibility of judicially imposed regulation of GHG emissions. Second Circuit decision
On September 21st, 2009, the United States Court of Appeals for the Second Circuit reversed a lower court ruling and held that a public nuisance suit brought against large emitters of GHGs could proceed. In Connecticut v. American Electric Power, eight states, New York City, and three land trusts (“Plaintiffs”) sued six large electric utilities that, in the aggregate, annually emit approximately 650 million tons of carbon dioxide (“Defendants”). Plaintiffs filed suit in 2004 claiming that Defendants’ carbon dioxide emissions contributed to climate change, which threatened public health and natural resources, resulted in environmental damage, and constituted a public nuisance. Plaintiffs sought a court order directing the power companies to reduce their carbon dioxide emissions by 3% annually for 10 years. The US District Court for the Southern District of New York dismissed the case on the basis that granting Plaintiffs’ requested relief would require legislation, making the issue a political question outside the court’s jurisdiction. Reversing the lower court’s decision, the Second Circuit found that Defendants’ contributions to climate change interfered with a “public right in protecting natural resources.” As a result, the Court declared the federal common law of nuisance governed Plaintiffs’ claims. The lack of a federal regulatory scheme addressing climate change was a key factor in the Second Circuit’s decision. The Court found that while the federal Clean Air Act addresses pollution and climate change, it does not yet require regulation of carbon dioxide emissions. In 2007, the US Supreme Court held in Massachusetts v. EPA that the EPA had the authority to regulate carbon dioxide under the Clean Air Act. The EPA subsequently proposed an endangerment finding that carbon dioxide is a threat to human health. However, the EPA’s proposed endangerment finding is not final and, more importantly, the EPA has not yet started regulating all sources of carbon dioxide. Therefore, the Court concluded that the federal common law of nuisance governed Plaintiffs’ claims as no comprehensive federal framework existed to displace the nuisance claim.
Climate change legislation & regulation
The Court’s decision comes at an important time in the US’s efforts to curb GHG emissions. In June, the US House of Representatives narrowly passed a bill initiating a nation-wide capand-trade program designed to curb GHG emissions. In September, Senators John Kerry (D-Mass.) and Barbara Boxer (DCalif.) introduced the US Senate’s version of a climate change bill. Senators likely will spend the next few months revising the bill as they try to secure enough votes for its passage. In addition to the activities on Capitol Hill, the EPA has taken steps to regulate GHG emissions. On September 30th, 2009, the EPA announced its intention to regulate GHG emissions from large stationary sources. The EPA and certain other federal agencies previously released a proposed rule establishing GHG emission and fuel economy standards for motor vehicles. In addition, on September 22nd, 2009, the EPA finalized its rule requiring certain emitters of GHGs to report their GHG emissions. The EPA estimates the rule will require reporting from approximately 10,000 US facilities and cover approximately 85% of the nation’s GHG emissions. Looking ahead
Over the next several months, there will likely be continued discussions about curtailing GHG emissions. In December, US representatives will attend meetings in Copenhagen where developed and developing nations will try to reach agreement on an international climate change accord. In addition, depending on progress with health care reform legislation, pressure may build in the Senate to pass a comprehensive climate change bill. The EPA is also expected to continue its efforts to regulate GHG emissions. In the meantime, the Second Circuit’s decision likely will spur other potential claimants to file suit against GHG emitters. The Court’s ruling is only binding on courts within the Second Circuit; whether courts in other jurisdictions choose to follow the reasoning of the Second Circuit is an open question. Additionally, the US Supreme Court could overrule this decision if Defendants decide to appeal. Finally, future claims of this nature could be preempted if a federal GHG emissions regulatory scheme were implemented. Sarah A.W.
