PNM Resources’ Safety Culture –
8
elec tric energy | summer 2011
Journey to Zero By John Haarlow, Director, Safety, PNM Resources
T
hrough its largest utility subsidiary, PNM Resources has been serving New Mexico customers for more than 90 years. Today, PNM Resources and its family of companies serve residential and business customers in New Mexico and Texas, building a solid reputation for shareholder value, customer satisfaction and service reliability. Through its utilities - PNM and TNMP - and energy subsidiary - First Choice Power - PNM Resources serves electricity to 859,000 homes and businesses in New Mexico and Texas. Our generation resources of 2,706 megawatts reflect a balance mix of coal, natural gas, nuclear and wind generation. In addition, the company has a 50 percent ownership of Optim Energy, which owns and markets nearly 1,200 megawatts of generation in the Electric Reliability Council of Texas market. Just a few short years ago, PNMR’s safety culture was similar to many electric utility companies around the country. PNMR had established safety as a core value of the corporation, believing that the health and safety of its most valuable asset, its people, was first and foremost to their business. But what does it really mean to have safety not just a top priority, but a primary value of the organization. The company’s culture had been built around keeping the lights on, keeping the power plants generating electricity, getting new services installed and energized, and reading meters. This operating philosophy (in conjunction with trying economic times) fostered employees’ notions that productivity and budgets are the main focuses for the organization. Therefore, in an effort to reverse that mindset and revolutionize its safety culture, PNMR set out to not only minimize work-related injuries, but eliminate them altogether. This “journey to zero” is a mission that addresses the company’s conviction that every employee should return safely home to their families every day. Step one in the organization’s line of attack against injuries was to develop and deploy a Corporate Safety Policy that clearly articulates the company’s vision to pursue zero personal injuries, and to cultivate a “Best-in-Class” safety culture. To accomplish this mega-undertaking, an Executive Safety
Committee, comprised of PNMR Senior Vice Presidents and Vice Presidents was assembled. PNMR’s mission as it relates to safety states “the company is committed to the continuous improvement of its safety program, with the ultimate objective of achieving a zero-injury safety culture and world-class safety performance that ensures the health and well being of all PNM Resources employees, contractors, and the communities we serve. PNM Resources believes this objective will be achieved with the commitment and active participation of all PNM Resources employees.” Once the safety policy was established, a significant challenge began: How would PNMR, and specifically leadership, turn words into actions? And so began the journey to transform behaviors of the company’s 2,100 employees in terms of fostering an environment where every worker not only elevates his/her own health and safety status to a position of supremacy, but also safeguards that of all co-workers. Baby steps! The organization began to implement small but significant approaches to exhibit its dedication to the nouveau safety philosophy. For example, (1) Safety data found a new home at the beginning of reports which are distributed weekly and monthly to senior leadership and also on the quarterly correspondence to its Board of Directors, (2) An injury notification process was established in order that leaders up to and including those at the senior level are alerted immediately following all work-related employee injuries. (3) The company made a pledge to investigate all incidents including both injuries and near-misses in an effort to not only identify root causes, but also to implement or amend procedures which will serve to eliminate and/or minimize the potential for future similar injuries. (4) Responsibilities with regard to safety have been introduced (Safety Expectations and Accountability Model, SEAM) to all PNMR employees from grass roots up to the company’s CEO. Examples include a designated number of “safety walks” each year, employee involvement as it relates to safety committees, and the assurance by leadership that every employee will be properly educated and trained to facilitate safety in all facets of the workplace. The organization has undertaken an initiative (in conjunction with the aforementioned strides) to instill awareness to the fact that in the end, leadership is accountable for the w w w. r mel .o rg

safety of its employees. In an effort to drive home PNMR’s commitment to a zero injury safety culture, those in positions of leadership must ensure that actions, decisions, and behaviors of the organization’s workers align with and advance safety as a core value. For that reason, PNMR executed a two day safety leadership workshop for the company’s working foremen up through senior level vice-presidents. The seminar focused on the significance and influence of leadership’s impact on behaviors beginning with an employee’s first day at work, during safety walks and/or subsequent to safety incidents. As a result of the leadership training, PNMR created and distributed a Safety Leadership Handbook which includes the PNMR Safety Policy, Expectations and Accountability Model, Incident Investigations Procedure, and Safety Walk, Safety Suggestions, Near-Miss forms, as well as key concepts addressed during the seminar. Over the past 15 months, we have integrated the use of Industry Safe as its primary tool for incident tracking, tracking and managing safety walks, tracking hazards that have been identified, and corrective actions. All of the above aid in PNMR’s development of an effective safety accountability system, as it is crucial to set forth clear expectations, modify unsafe behaviors, and ultimately reduce personal injuries. In addition, the web-based tracking tool offers software which assists with tracking and managing all safety training. Supervisors and managers are able to access this program. In effect the tool is a “one stop” site to aid in the efficient and effective tracking/managing of all safety training. PNMR’s corporate communications group has also played a key role in transforming the safety culture at PNMR by making safety a significant part of the messaging that is disseminated throughout the organization. After incidents are investigated, corporate communications will send out a Safety Bulletin to every leader throughout the organization providing a summary of the incident, the root cause(s) and the corrective actions to be taken. This bulletin is also posted on the company’s Intranet site, where all employees can access it. Corporate Communications will also run feature articles on business units, groups, and teams throughout PNMR that have achieved significant safety milestones such as one, two, three, etc. years without an injury and/or preventable vehicle accident. When PNMR’s CEO, Pat Vincent-Collawn, makes her visits to the electric service centers throughout New Mexico and Texas, or to one of PNM’s power plants, she will start the discussion on safety, often recognizing the employees at that particular location on their safety achievements, and reinforcing her commitment to their health and well being.

PNMR has developed and implemented, and/or improved a number of safety programs over the past 3 years; these include Lock-out/Tag-out procedure, Job Safety Planning and Tailboard procedure, Fire-Retardant PPE program, Equipotential Grounding, asbestos management, respiratory protection, etc. PNMR has also significantly improved the safety training management system. A major upgrade on the Employee Safety Manuals was instituted and new manuals were issued to every employee in PNM operations in 2010. Some of the key safety initiatives currently under way or in the developmental stage include 100 percent fall protection for linemen, advanced arc flash assessments and hazard mitigation planning for our network systems, developing and issuing “Supervisor-Led” Training Modules for our annual OSHA required trainings, continued deployment of a behavior-based safety program, and additional safety leadership training. In addition to cultivating an environment where all PNMR employees believe that their health, safety, and well being are of primary importance, the organization is diligently working to instill the mindset that all injuries are preventable, and that achieving our vision of everyone returning safely to their families every day is possible. PNMR has reduced the OSHA Recordable Injury Rate by almost 60 percent and Severity Rate by over 80 percent in just three years, which means PNMR is headed in the right direction. Although there is still a significant amount of work to be accomplished in order to cultivate a zeroinjury culture, realize “Best-in-Class” safety performance, and to ultimately arrive at our destination of zero, PNMR is forging “full steam ahead” to advance its dedication to safety. John Haarlow has served as Director, Safety for PNM Resources since June 2008. He is responsible for all safety aspects for PNM and TNMP. John can be reached at john.haarlow@pnmresources.com.

Lighting Experiences By Jerry Darmafall, Electrical Engineer, Longmont Power & Communications
The City of Longmont, Longmont power & Communications (LPC), began in August of 2009 to solicit on-loan samples of LED cobra head fixtures for testing and measurements from several manufacturers. Initial response was good as we had 12 participant manufacturers that had products available. One was essentially a retrofit bulb. Since that time, the larger lighting manufacturers have developed and released their fixtures. The original test consisted of primarily 150-watt HPS equivalent cobraheads that were loaned to us by the manufacturers. This test began in the fall of 2009. We took measurements of foot-candles (at certain distances), power consumption, power factor, and weight of each fixture. We are currently taking these early models down to return to the manufacturers. We had asked for a six month trial period but some have been up for 17 months. The best news overall is that there were no failures, all had power factors of .95 or better and all used less energy. Simultaneously we applied for a DOE EECBG grant for a formal long term pilot. We were approved for a $10,000

grant and based on the earlier prototypes and newer players, selected 12 manufacturers to quote two fixtures each based on an in-house preliminary LED specification. Eight manufacturers were selected and purchase orders were issued. One of the selected manufacturers selected was a retrofit module. We also have expanded research to include post top, shoe box and pedestal lights (maybe unique to Longmont). We are currently entertaining an acorn style fixture retrofit from a manufacturer. The technology and choices have vastly increased since this project began. From our testing we learned about the importance of the color-temperature range of LEDs. We have settled on a range of 4,000 to 5,500 degrees Kelvin which is a clear mid-day white light that allows much improved image recognition and true color rendering. The lower range does not seem effective and the higher range color is not very comfortable and is subject of research into its affect on eyes. This is not currently addressed with the IES lighting standards currently used. I contacted the Longmont Police Department to ask their impression of the original loaned fixtures, which were

A Flexible Solution to Power Generation in an Uncertain and Changing Market
By Esko Polvi, VP of Operations, PFBC-EET

elec tric energy | summer 2011
The Pressurized Fluidized Bed Combustion (PFBC) is an available established technology that can generate electric power economically and flexibly, environmentally friendly and is already today offering the solutions to the issues that are up for discussion in the next generation of energy policies. The availability of affordable and reliable electrical power supply has been and will continue to be one of the cornerstones for the growth of our economy and sustainability of our wellbeing. Considering the accelerating speed of technology development and regulatory complexity any long term business, such as power generation, is facing an environment with increasingly new and changing conditions over its life span. Hence, to stay competi30 tive, the power generation process must be flexible to adapt to various imposed conditions and anomalies that it will be exposed to over its life time. 25 Within the next 25-30 year horizon, in parallel to development of future energy technologies, efforts 20 must be made to make the existing energy generation technologies as reliable, efficient, environmen15 tally clean and economical as possible using the now known fuel sources of which the nuclear, natural gas, 10 and coal will still continue to be the major players. The increasing population growth and the retiring power plants will leave an energy demand gap that must be filled. In addition to this it remains to be seen what the impact of the catastrophic events in Japan will be on the US demand of additional natural gas and coal fired units. Considering the high cost impact on the power generation cost of increasing fuel prices the ideal future generation technology is very fuel flexible enabling the use of fuel sources with the lowest prices. Considering natural gas price elasticity to demand and supply fluctuation and the regulatory issues around nuclear fuel, coal has a major advantage in the form of price stability.
In addition to the steam production, to drive a steam turbine generator, the PFBC process utilizes even the flue gas mass flow to generate power through a gas expander making it possible to use wet fuel (up to 26-30 percent moisture) without any significant energy penalty. This unique feature makes the PFBC boilers very suitable for firing wet coal fines from ongoing coal production, impounded wet waste coals, as well as Western and Texas coals with high amounts of inherent moisture.

During the above rolling blackout the real-time electrical power prices reached their $3,000/MWH price cap. The commercial coal prices have seen some recent price pressure due to the increased demand from China and India which favors a boiler that can efficiently use the waste from the commercial coal production and from the huge amount of coal in the existing waste coal ponds and piles. The price for waste coal is expected to remain stable over the foreseeable future due to the abundance of waste coal in the existing coal piles and ponds. The burning of the waste coal is also a solution to the environmental problem the coal companies otherwise have of the additional waste that is added to the existing piles and ponds during the production of commercial coal. In addition to the plant operational availability wind and solar power are suffering from the natural variation in availability of wind and sunshine resulting in typical load factors of 15-30 percent. This variation must be compensated by other backup sources such as gas or coal fired stand by plants offering a spinning reserve ready to pick up the demand where the wind and solar drops off as well as quickly reduce load when the conditions permit those sources to pick up load again. Due to the pressurized process, compared to an atmospheric boiler unit, the PFBC boiler has a lower amount of steel that must be heated during the startup resulting in a waste coal fired boiler that can start producing power in 60 minutes. To enable the quick start the PFBC fluidized bed can be kept hot by burning carbon neutral renewable bio fuel or natural gas and then be ramped up to full load in one
18

hour using coal or a mix of renewable bio fuel and waste coal. By firing renewable bio fuel during the hot standby time the process can be considered to be carbon neutral. Within a one to two hour notice the PFBC boiler can fill the gaps between the actual demand and the fluctuating generation of wind and solar. PFBC boilers have been in successful operation in Europe and Japan for over 20 years. The plants in operation meet the present environmental requirements with no scrubbers and other pollution cleaning devices. The PFBC boilers are very fuel flexible without any significant impact on the combustion efficiency burning various coal qualities mixed with bio fuels etc. Due to the inherent benefit of the pressurized combustion process, compared to an atmospheric boiler, the physical size is very small making the PFBC suitable for retrofitting of old atmospheric boilers to improve the efficiency and environmental performance. Typically a PFBC plant with CO2 capture can replace an old atmospheric boiler without CO2 capture and still come ahead on the efficiency. The much smaller physical size uses a lower amount of alloyed steel making the boiler less sensitive to changes in material prices over the boilers maintenance life time. The availability of the existing operating plants has been in the 85-90 percent range that is in par with what is expected of a modern power plant. For a very efficient CO2 capture the PFBC pressurized combustion process is a perfect fit for the commercially available and proven Benfield pressurized potassium carbonate CO2 capture process.

I.e. a combination of the two proven technologies with over 20 years of successful operational experience can achieve already today what billions of dollar investments in other technologies try to accomplish. The PFBC technology is reaching efficiencies in the 40-43 percent range without pushing any material limits making it competitive with the most advanced clean coal technologies such as IGCC. By mixing in renewable biomass with the waste coal the PFBC/Benfield process can achieve a negative carbon footprint meaning that in case the carbon credit system is enacted the PFBC with Benfield carbon capture offers a new potential source of revenues in form of the carbon credits or a carbon offset of some other source in a power generators fleet. One beneficial user of the captured CO2 is the existing Enhanced Oil Recovery (EOR) market. The CO2 can, after the depletion of the oil, be permanently sequestered in the depleted oil well. PFBC-EET together with Consol Energy operates a Process Test Facility with a 1MW thermal output PFBC boiler which also has a Benfield type of potassium carbonate CO2 capture system. The test runs in this facility have confirmed that a negative carbon foot print can be achieved by burning a mix of waste coal and biomass at an insignificant level of emissions (2.8 ppm CO, 0.37 percent CO2, 0.4 ppm NO, and 6.8 ppm N2O). A PFBC plant is typically built of one to three 100 or 400 MW boiler units producing steam to one common steam turbine. The 100 MW units are readily available from PFBC-EET, Monessen, PA (www.pfbceet.com). From the economy of scale point of view it is beneficial to build large central power plants but from energy supply secu-

rity point of view it is preferable to have smaller local units, such as 100 to 300 MW PFBC plants that in case of problems on the grid can be isolated and quickly taken into operation. Considering the performance, features, and the fuel flexibility of the PFBC technology it can compete with the most advanced technologies and its unique features offers the present and future power generation markets the solutions needed for a reliable generation of electricity in an uncertain and changing energy generation market.

Winners Losers and
in Power Generation By Anthony J. Carrino, Senior Consultant, Power Generation, HSB Solomon Associates LLC
Introduction When it comes to asset performance, just what exactly defines a winner? Fifteen plus years of analyzing power generation asset performance data has provided us the necessary insight to answer such a question. Looking at trends in one segment in particular, the US power industry, coal units have on average advanced performance continuously over the past 10 years. So, the real question is, what differentiates the top performers from the rest? To answer this question, we have to address more specific questions such as “Who wins when we perform better?,” “What drives improvement?,” and “What characteristics do winners have that losers in the sector do not exhibit?”
Who Wins? First, let’s consider where US coal units have been. Figure 1 shows the overall average trend of Net Capacity Factor (NCF) performance during the period from 1997 through 2007, before the economic downturn hit the global economy in 2008–2009. Looking at Figure 1, it is clear that power generation customers have won. If coal generators that supply the majority of production in the sector made utilization improvements during the 1997–2007 period, the average electricity consumer reaped the benefits in terms of more reliable power and lower costs due to improving utilization of w w w. r mel .o rg

third-party assessment of how we are doing.” Basically, they were told to do it. Those companies are typically looking for the cheapest and quickest way to say they have met the obligation. Often, those companies get a high-level, inconsistent sampling of data, satisfy the request, and they are gone; they did what they were told to do. They lose out because they do not look at measuring performance as a tool in the toolbox of continuous improvement. Other companies benchmark internally only, for reasons such as, “are we showing continuous improvement in performance from year-to-year?” These companies understand that by consistently watching trends, they can show whether they are making progress. But knowing whether or not you are better among your own assets has shortcomings. If you operate a fairly small fleet with few assets, the sample size is too small from a statistical perspective; results provide only limited information. On the other hand, internal benchmarking on a larger fleet of assets might be an advantage, but if the differences (fuel, operating mode, age, design, etc.) between those assets are used as excuses for poor performance, your entire fleet may not be able to fully achieve its goals. Good performance measures must include broader samples and must allow for normalization of differences. Some companies want an external view, to understand if they are improving faster or slower than the competition. Let’s face facts, during the last 10-12 years, our US coal assets have been adjusting to many factors—from fuel switching and regulatory constraints to introduction of more gas-fired generation and renewable generation sources. Companies that have failed to “keep up” have
26
cost customers more money for their power and probably lost shareholders value. Our experience in analyzing performance data tells us that winners tend to adapt quicker to changing constraints and market forces (typically within one to two years) while losers tend to take four, five, or more years to adapt, to learn the lessons, to learn how to do business differently. The bottom line, your organization will respond to what you are measuring. Broad performance monitoring will allow your team to respond faster as change occurs.

Regardless of whether your company has “good” performing assets or “poor” performing assets, if the only concerns for comparisons are internally focused or driven, it is still possible to lose ground in the marketplace with “good” performing assets. One reason might be that management methods, programs, or strategies across your generation fleet are consistent, maybe consistently out of date or not evolving as fast as the competition. The old adage is, “doing the same things the same way over and over and expecting different results is the definition of insanity.” What do you think might be the result from an annual budgetary management approach defined by “…last year’s budget less X%”? “Cutting your way to success” may occasionally be essential in the short-term (think of the 2008–2009 economic downturn), but it is not a sane strategy from a longer-term commercial or earnings perspective. Take Figure 4 for example. It is easy to understand that continuously cutting costs (training budgets, planned maintenance spending, etc.) ultimately results in units with more inefficient breakdown maintenance spending, more human errors, and more commercial impact by having to buy or run more expensive capacity. As managers, it is necessary to step back from focusing on only the cost side of the equation and take into account the commercial impacts of spending decisions. Reductions in force, workforce rationalization, etc. are frequently sold by management consultants as a quick fix. Typically, the workforce reduction is offset by utilizing more contractors. Check the box, plant staffing is lower now. But what about the results? Cost may have initially dropped by using lower cost contractors, but that is not the full picture. There are multiple paths to success, just choose your resource mix, but remember to measure performance before and after the change. If human resources, as plant or company employees, are traded off for contractors, the real question is “does the new mix of human resources provide us with better or

worse performance, in terms of net revenue?” Hiring third parties may be a rational approach, even a best practice, by bringing in expertise only when required. But if contractor work quality control is not monitored and corrected when necessary, the performance of the asset can decline. Winners understand that when a change is made, the effects of that change cause ripples throughout the asset and/or organization, and you must monitor those related performance measures to ensure that the change maintained or brought the desired better results. Another fallacy in management thinking (and even in a few management consultants’ not-so-humble opinions) is that generation assets can be first-quartile performers in all categories at once. Having the lowest cost, lowest EFOR, lowest heat rate, lowest staffing, lowest commercial losses, all with the same generating asset over the long-term is as unlikely as correctly picking the final four teams in the NCAA basketball tournament…every year! Without thinking about the big picture, unrealistic and/ or conflicting goals are set, and assets and organization suffer when trying to do the impossible. Winners understand that power generating assets operate “in the real world” and they must focus on a small set of key success drivers to optimize any given asset. This thinking is not restricted to just base-load coal assets, it includes intermediate and peaking units as well. Balanced scorecards can be fantastic tools, but each asset needs to have its own measures of success and performance drivers to best optimize its market role in a fleet. If we think mostly from a plant mindset that our generating units only are measured on technical performance measures, we cannot adequately translate potential
28
technical improvements into financial business needs to management. If we think only from a financial management mindset, we can’t understand how a dollar spent in one part of our plant or unit is different than a dollar spent in another part. Winners understand that “how much you spend” matters, but understand better that “how you spend what you spend” determines success. The data proves it.
elec tric energy | summer 2011
Solid data (in terms of technical aspects), financial and human resource utilization (as business inputs), and performance measures (as success indicators), must be translated into useful information to manage the business better. These days, deciding more by using data and less by taking apart equipment and inspecting saves money. Benchmarking, if done by looking at the big picture (and that means that nothing is left out of the performance monitoring equation—such as contractor utilization, commercial market performance, statistical analysis, emissions economics), becomes a tremendous tool to help manage through change and adapt quickly when performance falls short. If you are not considering the bigger picture, when your operating environment changes, your business performance measures may not even see the change until others have passed you by, showing better performance faster than you. Shutdowns of older, smaller coal assets are no longer just around the corner, they are here. The coal assets remaining in service will be pushed even harder on performance, with new EQCS equipment, and with increasing age. The impacts of the Japanese nuclear plant failure on our US electricity market will play out over the coming months and years. Renewables are too inherently “good” to abandon, even when they occasionally get wrapped in “still air” and “shade.” And the natural gas boom is still playing out. EPA doesn’t appear to be slowing down. Change is accelerating. Go it alone if you dare and try weathering these storms without data. We know what the winners are doing; the data is driving both their business decisions and quantifying their performance results.

LiDAR Process and working with the Data Collection of LiDAR data is often times a preferred option for attaining survey points required to build transmission line models. Once the decision has been made to utilize LiDAR on project, it has typically taken approximately two to three months for El Paso Electric to get useful line models in hand. Although, the actual data collection and processing timeline can be shortened, depending on project needs. For projects that may not be as time sensitive, many times mobilization charges can be shared by neighboring utilities. For example, if a LiDAR provider will be flying back to its home base roughly over your project area, the associated mobilization charges are often shared with other utilities, significantly lowering the cost of data collection. Additionally, utilities often have the option of funding the data capture at one time, while funding the data processing at a later date. There are often very large data files associated with LiDAR and aerial photography, which initiated El Paso Electric’s transmission line design group to recently purchase new computers to handle these data sets. The millions of LiDAR data points and high-resolution images may bog down slower computers, while a few thousand dollars for a new desktop computer may save your design engineer considerable time and frustration. Before the actual data collection takes place, and in order to build an accurate model of the conductor, line loading information at the time it is flown is necessary so that an as-flown conductor temperature can be accurately derived. Most LiDAR companies will provide basic weather information at the time of
32
elec tric energy | summer 2011
data collection, but it is the utilities responsibility to capture the line loading information.
The Verification Value of LiDAR Once the LiDAR data has been collected, it enables the utility to build highly accurate, as-built, electronic models of existing transmission facilities. An electronic model of a transmission line built in PLS-CADD, utilizing LiDAR data, is the foundation for many engineering studies needed to verify line clearances for sag-limited lines, among other things. This method of building a LiDAR based model is often times El Paso Electric’s preferred methodology for verifying line clearances in response to NERC requirements. These PLSCADD models, created with this LiDAR data, are also useful when responding to planning requests and determining any modifications that may be necessary to achieve a desired line rating with existing or new conductors.
Coupling Handheld Technology with LiDAR Data for Vegetation Management The benefit of LiDAR data has also been realized for El Paso Electric in the vegetation management arena. El Paso Electric transmission engineers are currently using a new handheld vegetation management monitoring device, the Aerotec Top Gun Veg-Tool, to create significant improvements and savings in vegetation management along its transmission lines. The Aerotec Top Gun Veg-Tool is a lightweight, single-operator device that from a single spot can be used to take shots of multiple trees within a given span to provide accurate and easy-to-read
vegetation clearance information. The device integrates Laser Technology’s TruPulse ® 360 laser rangefinder and compass data, TOPCON’s GRS-1 GNSS position data, LiDAR-supplied multiple surface databases and GIS management software. In field tests along portions of the El Paso Electric Springerville, Arizona to Deming, New Mexico 345 KV, three phase transmission line, engineers compared Top-Gun results against physical hardcopy and digital maps from a current LiDAR clearance inventory to verify that the appropriate clearance trees had been flagged and marked completely. Once a transmission line has been flown, the LiDAR data was used to create digital topographic ground surfaces, and line clearance modeling buffers around the energized conductors these surfaces are saved in the Top Gun unit for later and repeated use by line patrols for years to come. In addition to storing LiDAR surface data the tool automatically maintains records of the clearance of each checked tree using GIS information that includes the date and time, X, Y and Z location data and the clearance information. A variety of additional attributes can be recorded and saved as well, such as; species type, tree diameter at breast height, and if desired, growth can be observed year-to-year. The clearance record of each tree checked is archived as a Shape file in a central GIS database. Trees that may pierce the National Electric Safety Code (NESC) clearance envelope or a growth buffer are recorded and flagged for cutting or trimming. If tree cutting or trimming permission is required from a permitting agency, such as the United States Forest Service or
Bureau of Land Management, a complete data set of the trees that pierce the buffer around the hot wire can be provided to the agency as well. Initial training of the El Paso Electric personnel, including calibration, start-up, field use, data download and data model handling and archiving took approximately two hours, and in very rugged terrain, more than five miles was covered on the first day. The TruPulse 360 laser rangefinder and compass, connected via Bluetooth, enables a single operator from a single spot to easily point, shoot and record multiple suspect trees up to 600 feet away above and below the observer. Gathering this data remotely is only possible because the TruPulse 360 is able to capture measurements to features without the need for a reflector or personnel holding a prism pole. Because the LiDAR modeling buffer can account for high-load and hot summer wire conditions, El Paso Electric crews can shoot the trees at any time of the year and still determine if the tree pierces the envelope.
Final Thoughts LiDAR data are a great foundation for building electronic models of existing transmission lines. With the dynamic nature of many transmission line upgrade and modification requests the transmission engineer is faced with, LiDAR based electronic models make responding to requests and designing upgrades much easier and quicker than before. In addition to aiding in creation of electronic models, this data can be useful for years to come
by the transmission engineer for many other uses as well, such as vegetation management. The utilization of this data and technology is of great benefit to El Paso Electric. Ryan Paulk is a Transmission Engineer at El Paso Electric. He has worked at El Paso Electric for approximately two years and has been involved in the electric transmission industry for over 10 years.

Fukushima, Japan and the Impact on Nuclear Generation

What Happened at Fukushima? By Dr. Jeffrey C. King, Assistant Professor and Interim Director, Nuclear Science and Engineering Program, Colorado School of Mines
W
riting about nuclear engineering events can be hard. When everything goes right, like it does the vast majority of the time at the 104 nuclear power reactors in the United States, no one pays any attention. When something goes wrong, like it did this past March at four of the 55 nuclear power reactors in Japan, everyone pays attention and there is a demand to explain a lifetime of knowledge and experience, complete with obscure units and facts no one paid any attention to the day before, in five minutes or less. On March 11, three of the reactors at the Fukushima Daiichi power station were operating and three were shut down for maintenance. When the earthquake hit, the control rods in the three operating reactors were inserted, stopping the nuclear chain reaction. About 2 minutes after this, the last fission occurred and the only heat source in the reactors was the radioactive decay of the fission products - which is a small and steadily decreasing fraction of the power of the operating reactor. A few minutes after shutdown, the reactor power was less than 2 percent of the operating power. Today it is less than 0.5 percent. This is a small fraction, and normally easy to control if you have a steady supply of water. The diesel generators at the reactors started immediately after the earthquake and were powering pumps to provide that water supply; unfortunately, the backup generators were all disabled when the tsunami resulting from the earthquake struck Fukushima. Without a water supply, the temperature of the fuel began to increase, leading to damage to the fuel cans, and ultimately to the partial melting of the fuel itself. The damage to the reactors’ fuel cans and fuel resulted in two very significant problems. The first was that the gaseous fission products (primarily cesium-137 and iodine-131) were released into the reactor vessel and containment. The second was a reaction between the zirconium alloy and the steam in the reactor, which led to the production of significant amounts of hydrogen gas, which is very flammable. As the reactors continued to heat up and the pressure in them increased, the operators realized that they needed to reduce the pressure in the reactor vessels, leading to a decision to vent the reactors. In venting the reactors, the operators knew that they would be releasing radioactive materials to the environment, but the release of the gaseous fission products was felt to be a smaller risk than allowing the reactors to rupture, which would have resulted in the release of a much greater amount of radioactive material. Unfortunately, venting the reactor vessels also allowed the hydrogen gas to come into contact with oxygen, leading to explosions that destroyed the upper parts of the buildings housing Units 1 and 3. At Unit 2, a hydrogen explosion may have occurred within the reactor’s containment structure, opening a pathway for radioactive material to be more easily released to the environment. Once emergency cooling water was supplied to Units 1, 2 and 3, the nuclear fuel began to cool down, effectively ending the first stage of the event. However, the fuel rods at Unit 4 had been w w w. r mel .o rg
35
removed from the reactor before the earthquake and were stored in water pools at the top level of the reactor building. After several days without cooling, the water level in the spent fuel pool at Unit 4 had dropped to the point that the zirconium cans of the fuel in the pool began to react with the water in the pool, leading to the production of hydrogen and a subsequent explosion, which severely damaged the Unit 4 building. Using specialized spray trucks, the operators were eventually able to supply water to the spent fuel pools, bringing this part of the event under control. The final stage of the event was the discovery of heavily
contaminated water in the basement of several buildings on the site. This water, which may have come from the water injections into the three damaged reactors, particularly Unit 2, has hindered the ability to restore offsite power to the plant and restore recirculating cooling to the reactors and spent fuel pools. Additionally, the earthquake resulted in damage to some of the wiring and piping trenches on the site, allowing some of the contaminated water a path to flow directly to the ocean. Stopping these leaks, followed by pumping the contaminated water to tanks for treatment, is bringing this stage of the event to a close.
Fukushima Daiichi Implications for U.S. Nuclear Plants By J.K. August, VP, Operations, CORE, Inc.
A
fter Fukushima , the U.S. Nuclear Regulatory Commission and its counterpart, the U.S. Department of Energy, began reviewing risks associated with light water reactors (LWR) operating in the U.S. The LWR’s glass jaw − Zircalloy cladding − reacts with water under loss-of-coolant conditions. As agencies answer how well the Fukushima nuclear complex performed, we should ask what lessons Fukushima holds for U.S. policy on nuclear energy, what was its full cost and what strategic implications this hold for the U.S. agencies, industry and their nuclear strategy. They should address why the U.S.− indeed the world − keeps all its nuclear “eggs” in one basket − the LWR reactor.
Long-term Consequences Restoring capacity lost from the units and cleaning up the site will be significant. From U.S. cost experience decommissioning Three Mile Island and other contaminated sites, an initial estimate of US$30 billion is probably low for cleanup. Long term, the NRC may require U.S. plants to change designs. Most likely, changes will address emergency diesel generator threats, spent fuel pool weaknesses and off-site grid connections. Secondary design changes could address means to charge water to the reactor in a station blackout (SBO) event. Emergency planning for Beyond Design Basis Events (BDBE) may be required such as general area evacuation and site support, as well as financial intervention.
Fundamental Reactor Design Attributes Metal clad reactors have high power density fuel with low heat capacity and relatively little strength at higher temperatures. Combined with chemically reactive cooling water, intrinsic cladding characteristics limit these designs in undercooling events. To mitigate or control these requires special systems with other complex considerations. They make design and operations more complex, contributing to higher costs. New reactors designs should be built “right” from
36
elec tric energy | summer 2011
fundamentals. Ideally, they would be intrinsically simpler. Otherwise, costs soar and risks remain hard to project with high levels of certainty. Uncertainty could mean the loss of public and financial support for new nuclear generating plants. People could perceive nuclear risks as simply too high to accept. After Fukushima, public disillusionment with nuclear plants could put all nuclear technologies at risk. We should consider other reactors designs that are more resistant to fuel overheating weaknesses. One of these is the high temperature gas-cooled reactor (HTGR). That design uses ceramic-coated fuel within a high heat capacity matrix. The graphite matrix also retains its properties well above the temperature ranges common for metal reactors. Furthermore, Helium cooling eliminates chemical coolantfuel reactions. The result is a design with more inherently safe characteristics. If Fukushima has a positive aspect, it may be to renew interest in other types of design. Are we willing to invest in nuclear power today? Clearly uneconomic or unreasonable energy technologies will find it more difficult to get financial support. If the answer is, “Yes,” nuclear power will need a concerted effort to improve financial risk outcomes for lenders. To be attractive, nuclear power needs lower costs and risks. We should evaluate ways to improve new reactor integrity and safety with open minds, unfettered by LWR thinking.
Susceptible LWR Plants Generation 1 through 3 nuclear plants that are operating should be reviewed for hardening to natural events. Where that can be done simply and at low cost, design or operating changes with high safety payback and lower risk should be pursued. We should also integrate and simplify the current complex framework. Occasionally overlapping requirements aren’t clear, or parallel benefits get overlooked. Post 9-11, spent fuel pool (SFP) and core protective actions might have been applicable to this event. In any event, we should reconsider the question of spent fuel storage and its ultimate disposition in the U.S., where it remains stored onsite. Finally, we should re-examine
potential for radioactive water to leak flowing outside containment. Especially after natural events like seismic loading, cracking initiated may allow radioactive water from flooding to lead outside via common drains, chases and conduits. That can compromise secondary containment. Lastly, we should reevaluate multiple event scenarios with logical event scenarios. While the combined tsunami flood was well beyond predictions, the combination of events was not a surprise.
Evaluate New LWR Designs Operating Susceptibility Generation 3+/4 nuclear plants designs should be reviewed for hardening to natural events. Fifty years of adding on complex overlapping new rules and requirements have led to a complex framework customized for LWR designs. We should make a strategic decision to accelerate new design developments based on other technology. That will require a technology neutral framework.
Conclusions What should the nuclear industry do? It should begin reexamining new plant design processes at their most basic level. That should start with fundamentals, not a particular design prescription. It should support innovation to encourage thinking “outside the box.” We need to improve transparency by providing more intuitive design processes. (See Culture of Complicity Tied to Stricken Nuclear Plant, New York Times, Wednesday, April 27, 2011.) We should also simplify the designlicensing process to encourage the use of better cost-savings technology. That should include relational databases to capture critical plant design content from documents. That would help licenses complete their own design bases so they can reduce the licensing burden carried, directly in operations.
To make nuclear energy viable again, nuclear investments must have moderate risk. They must be attractive. We should reduce or eliminate complex safety mitigation systems characteristic of LWR − one reason for their high costs. We should also strive to reduce the many “add-on” costs derived from inherently risky designs − emergency plans, dry cask storage, security forces … and their associated management and maintenance costs. We need a new breed of intrinsically safer reactors − as much for financial investment and cost, as protecting the public health and safety. We should stop imposing LWR requirements on safer, innovative designs in ways that financially penalize and block them, by increasing their costs. After all, these are the future of nuclear power for U.S. and the world. PCStheMobile RMEL Ad 5-4-11 5/17/11 10:07 AM Page 1

A Current View of Public Health and Safety Consequences of the Fukushima Nuclear Event By Dr. K. Ronald Laughery, Former President and founder of Micro Analysis and Design, Inc. and member of the American Nuclear Society Public Policy Committee
F
rom the standpoint of public perception and, therefore, the future of the nuclear power, the central issue arising from the Fukushima nuclear power event will be how it affected public health and safety.
The Radiation Releases Examined In an attempt to categorize and address radiation release issues, I reviewed the print and online media from the period of March 11 – April 10, 2011. I then gathered and analyzed radiation level and dispersion data from a variety of data sources including print and on-line media as well as Tokyo Electric Power Company (TEPCO) reporting sites. As appropriate, I compared these to different criteria for radiation exposure levels to make a determination of whether the radiation to which the public and workers at the site are being exposed presents health risks. From data collected, I developed the following five major categories of radiation issues:
I ncreased Airborne Radiation Levels: Based on Fukushima City Health Office’s radiation exposure data, I estimated a total of 4.2 milliSieverts (mSv) of radiation exposure outdoors from March 11th through April 12th. Using the conservative 65 percent shielding factor, I estimated that the highest radiation level that an individual who stayed indoors outside of the evacuation zone was exposed to was 3.7 mSv as of April 12th. While the Fukushima event is not over and future radiation levels will drive these exposure levels higher, my conclusion was that there will be minimal health effects to the public from airborne radiation barring some unforeseen radiation release event.
R adiation Inside the Plant: Highest reported level was 1,000 mSv/h at a pool of water in turbine room of reactor two; Annual dose limit raised for workers during Fukushima emergency to 250 mSv/year; On April 1st, 21 workers were reported to have been exposed to levels of over the generally accepted limit of 100 mSv, but none over the 250 mSv limit. To date, there have been no reports of radiation-caused incapacitation from plant workers.
R adiation Contaminated Food: On March 19th, tainted milk was found 30 km from the plant and tainted spinach was collected as far as 100 kilometers to the south. However, it was reported that the levels were such that, if a person consumed these products continuously for a year, their radiation
38
elec tric energy | summer 2011
exposure would be about that of a single CT scan (about 7mSv). Radiation levels were not found in all food tested. Past and future risk to public health from the food supply appears to be very small.
Tokyo Water Supply Contamination: On March 22nd, 210 Becquerels of radioactive iodine per kilogram of water (Bq/kg) were measured in part of the Tokyo water supply. The limit for infants under 1 year old is 100 Bq/kg; the limit for humans > 1 year old is 300 Bq/kg. This led to a recommendation to infants and nursing mothers to stop drinking Tokyo tap water until dehydration concerns caused Japan’s leading obstetrics and gynecological organization to say pregnant and nursing women should continue to drink tap water even if the levels of radioactive iodine rise up to 500 Becquerels.
Release of Radioactive Water into the Ocean: After the leak was plugged on April 6th, ocean radiation levels dropped rapidly. However, on April 5th, fish were caught near the plant that showed Cs-137 levels at twice the limit, and on April 10th, other fish were caught with lower amounts of Cs-137, but still over the limit. The Japanese government is monitoring the fish caught in this area of Japan to ensure that tainted fish do not make it into the food supply. Overall, the likely public health consequences of this radiation release appear minimal. The second source of seawater radiation contamination is from the release by TEPCO of low level radioactive wastewater into the sea to make space for storage of more radioactive wastewater. TEPCO officials estimated that adults who eat fish and seaweed exposed to this seawater daily for a year would receive approximately 0.6 mSv. As such, the public health and safety consequences of this second radiated water release appear minimal.
Summary This is an ongoing event and the above analysis should be seen as a status report, not as the final word on radiation effects on the public from Fukushima. However, assuming radiation levels continue to drop and the government continues to be vigilant with respect to monitoring the food and water supplies, the net effect of the Fukushima event on the general public should be very small. Workers at the plant face the greatest risks, though with increased use of robots, careful staff management, and continued reductions in radiation levels at the facility, I believe that even these consequences will be limited. Given the age of these reactors and the severity of the event that precipitated this – a 9.0 earthquake and the ensuing tsunami – I suggest that these limited effects on public health and safety are extremely encouraging with respect to the underlying safety of nuclear power.
Fukushima Fallout By Cmdr. Don Reynerson, Consultant, The Phoenix Index, Inc. and The Barrington Group
A Solution For America In the short term all 104 US power reactors should be inspected by a non-industry group reporting to USDOE to assure hydrogen mitigation systems with dedicated emergency on site power sources are installed and the vent paths, if containment venting during an accident, are capable of structurally withstanding the vent dynamics – and upgraded accordingly. These two issues have been addressed for over 30 years in the US with still no completed back fits on many plants. A long-term solution, born in the 1980s to address the post TMI depression in the NSSS and AE firms, is to fully standardize families of nuclear plants “right down to the wall paper”. In the circa 1990 period, the Nuclear Power Oversight Committee (NPOC) sheepherder this approach and was composed of senior executives from NSSS (Nuclear Steam System Supplier) vendors (GE and Westinghouse), AEs (Architect Engineers) and utilities and trade and regulatory organizations. NPOC published a document “Strategic Plan For Building New Nuclear Power Plants” in 1990 with yearly updates in the 1990s. Much progress was made in the development of new, safer NSSS islands and the basis for one-step licensing was also developed. BUT, one aspect vital to the rebirth in a safety and economic arena was full standardization of families of plants. This has not happened as envisioned by NPOC in the 1990 timeframe. I quote a passage from a paper presented by Admiral H.G. Rickover in August 1979 after the TMI disaster (meltdown). It is entitled “Differences Between Naval Reactors and Commercial Nuclear Power Plants”. I quote: “Plant designs, equipment, control rooms, training, etc. should be standardized insofar as practicable… two distinct benefits would result. First is that larger numbers of engineering man-hours could be applied to the standard designs than to each of many different designs. The second benefit relates to the training of operating and inspection personnel.” This important paper by Rickover also makes many important recommendations that would lead to safer, more economical commercial plants – few in substance have yet to be adopted. Maybe the meltdowns will result in a reexamination of the approaches now in place for both operating and new designs and business practices. I am not hopeful. The American Commercial Industry (NPOC) did embrace full standardization in circa 1990 – “right down to the wall paper” for each family of new plants. Many involved expected to design, build, license and start up ONE plant - then build 10-20 identical plants (site specific differences only were to be accommodated in this approach). The plants of course would be safer, life cycle costs lower and capital investment after the first plant essentially fixed with
minimal changes due to intervention and regulation as the plants were completed. But there would be a lower number of hours for AEs, litigators and regulatory agencies over the lives (40-60 years) of the plants. The advantages for the public were clearly obvious. The American industry would be wise to review the approaches of the 1990s (NPOC) and Rickover’s suggestions and fully embrace complete standardization given the massive catastrophe in Japan (American Designs) before additional licensing, design and construction activities are affected. This should be done by USDOE under a mandate from the President and not by industry interface organizations. Also nationalization of commercial nuclear power (French model is a good place to start) should be seriously considered – nuclear power deserves a future but not within the culture evolving since the early 1950s. The future could be brighter for both the public and the industry IF changes in major approaches are fully implemented. Dr. Jeffrey C.

An SRP power system operator oversees generation facility controls during a crisis training drill. SRP is developing an enterprise strategy for smart grid cyber security; as the grid becomes intertwined with more data and communications technology, information must be managed securely.
SRP Ahead of the Smart Grid Curve By Mark Estes, Senior Corporate Communications Strategist, SRP
Central Arizona’s Salt River Project (SRP) has been investing in smart grid technologies before the term “smart grid” became an industry catchphrase. The utility continues to refine and develop its advanced power grid infrastructure today. SRP is a participant and original funder of the Electric Power Research Institute’s (EPRI) Intelligrid program that would link grids’ communications and safety systems to create a central management system for a quicker-healing grid. Intelligrid program participants are building the technical foundation for a smart power grid to boost reliability, capacity and customer services. Last year SRP finalized an agreement with the U.S. Department of Energy (DOE) to fund half of an ambitious three-year, $114 million project. The effort will more than double SRP’s smart meter deployment, adding a half-million new meters to an impressive inventory of about 480,000 smart meters already deployed. When the project is over, SRP will be one of the very few utilities offering advanced metering services to all customers.
40
elec tric energy | summer 2011
The project also includes developing and implementing a comprehensive meter data management system that will support one of the largest wireless smart meter networks in the nation, if not the world. DOE funding comes from the American Recovery and Reinvestment Act’s Smart Grid Investment Grant initiative, the largest energy-grid modernization investment in U.S. history.
Grid Needs to Evolve Why the push for smart grid development? While today’s power grid is one of the most impressive accomplishments of the past century, it has limits. Electricity flows one way on the current grid, from the power station to the customer. The utility does not get much information about how power is used. Customers have little sense of how much power they are using or how much it costs until they receive a utility bill. Because of population growth, bigger houses, and more energy-hungry electronics and appliances, electric peak demand has outstripped transmission system growth every year since
1982. This has taxed the grid – three of the five largest blackouts of the past 40 years have taken place since 1996. The existing grid also is not designed for handling power from renewable energy sources such as wind and solar. If the wind suddenly calms, or clouds cover the sky over a solar panel array, hundreds of megawatts become unavailable within a few seconds. It is difficult for utilities to respond and adjust quickly with today’s grid. Smart grids use advanced communications, computing and electronics to optimize system reliability and power delivery. A comprehensive smart grid would enable an array of technologies that would enhance the power grid’s communication capabilities, efficiency and transparency. In short, the power grid would change from a one-way channel to a two-way network, with much more information available at different junctures. A nationwide “smart grid” may become the platform for an enormous range of new innovations and applications in energy, much as the Internet did in computing. The cost of turning the nation’s electric transmission and distribution system into a “smarter” grid could cost up to $476 billion. But, according to EPRI, a serious investment in a more modern, automated system could also yield between $1.3 trillion and $2 trillion in benefits.
SRP’s Smart Choice SRP has been eager to take the path less traveled since its inception in 1903 when it was created through the provisions of the National Reclamation Act. Originally intended as a water provider, SRP began dabbling with power generation from the get-go when its first dam was being built. Excess power from site construction generator was provided to nearby mines and businesses. When a powerhouse was built at the dam and a permanent generator placed, the entity that would become SRP established itself as the nation’s first multipurpose reclamation project. As more dams were added along the Salt River (hence the name, Salt River Project), they were equipped with hydroelectric facilities. As central Arizona grew, rural residents sought the same service city dwellers got. So SRP began building power lines in the late 1920s to serve rural households. By 1930, when only 25 percent of rural America was electrified, 80 percent of central Arizona homes had electric service. Today SRP is one of the nation’s largest public power utilities and a major water supplier to metropolitan Phoenix. The power business, which operates as a municipality, provides electricity to more than 940,000 customers in a 2,900-square-mile area that spans three counties. SRP has almost 8,100 megawatts (MW) available to serve peak demand and a reported annual total sales 33,064 gigawatthours in 2009. SRP has a 493 MW of renewable power, 57 percent of which comes from hydroelectric facilities. SRP also owns more than 1,500 miles of transmission lines and

1,600 miles of fiber optic lines. Given its customer base and variety of generation assets, SRP developed a solid network of fiber-optic and wireless communications. SRP Telecom was created in 1996 to derive additional benefit from excess fiber-optic and wireless communications assets. SRP’s fiber network spans all or parts of 15 cities, allowing it to be extremely flexible in designing fiber solutions. SRP Telecom serves primarily telecommunications service providers and large business customers, and has grown to become one of the nation’s largest and most successful utility telecommunications concerns.
Smart Meter Deployment Began in 2003 Given that SRP had invested in a comprehensive fiber-optic network capable of supporting large-scale, smart-grid technology, the next step was smart-meter deployment. SRP began its smart-meter program in 2003, and soon was installing about 100,000 meters a year. Smart meters are an important component in smart grids. Unlike regular meters, smart meters can send back data. This makes it possible for utilities to read meters remotely, gather load information and pinpoint the location of power outages more precisely. These meters also enable utilities such as SRP to upgrade web-based resources and services that can greatly aid electric customers with energy and account management as the level of detail and user-friendliness increases. Because smart meters help our customers manage energy consumption, SRP can offer innovative price plans, such as Time-of-Use and the EZ-3 that encourage customers to reduce power use during peak hours. SRP also offers M-Power, a prepay option for residential customers that is largest program of its kind in North America. The result? Customer satisfaction rates are 90 percent and higher for SRP programs such as M-Power that are supported by smart meters. w w w. r mel .o rg
41
Smart-meter technology also helps SRP reduce peak demand through efforts such the PowerPartner demand-response program for commercial customers. PowerPartner was developed for eligible high-use SRP customers who can voluntarily reduce power consumption during peaks of electricity demand or high wholesale electricity prices. SRP has used a phased-in approach in its smart-meter deployment and has emphasized quality-control testing. SRP’s smart meters are manufactured in the United States by Elster Group, one of the world’s largest electricity, gas and water meter manufacturers. To date, SRP has deployed about 630,000 smart meters, which customers use to monitor and manage their energy use. SRP estimates that this smart grid solution has saved more than 386,685 hours in labor, avoided more than 2 million driving miles for field visits and conserved 200,822 gallons of fuel, which helps reduce SRP’s carbon footprint.
Backbone Systems being Developed Using A “Roadmap” Data from the new smart meters also will enhance operations in a number of other areas at SRP. Load forecasting will be improved, as well as supply and trading efforts. SRP also will know more about voltage fluctuations to pinpoint issues within the system, down to the transformer. This will help better manage outages, identify power quality problems and target possible power diversions. SRP’s core smart-grid investments reach far beyond smart meters, though. Before realizing the full potential of enduser benefits, utilities must start with the backbone of a smart grid system and gain benefits on the utility side. At this stage, it requires SRP expanding infrastructures in three key areas. Enhancing communications systems at the transmission level – Enhanced systems begin with SRP’s fiber optic

cable network but also extends to mobile communications, system automation and network controls. SRP’s communication system consists of a broad array of infrastructure facilities and technology platforms worth more than $120 million, including infrastructure, voice systems, data transport systems and an operations network. Over the past decade, SRP’s communication infrastructure has grown significantly in size and complexity to support an increasing number of critical business functions. Continuing smart grid development will drive communications needs throughout the electrical grid, involving sufficient backhaul capability in the substation network and extending into the last mile for advanced metering infrastructure and other transmission and distribution applications. There will be a continued progression from serial communications and time-domain multiplexing (TDM) to packet-switching, internet protocol (IP)-based networking that will fundamentally change how communications needs are met. Commercial telecommunications will evolve from TDM circuits to ethernet for backhaul services. Investing in IT infrastructure – Much of the smart grid requires linking information technology with operations technology. A successful smart grid IT infrastructure requires unified communications to efficiently manage and use data across multiple smart grid components and corporate departments. The increased complexity and dependency on the communication network will require a focus on operations and advanced network management tools, including implementing a communications network operating center. As communication infrastructure components approach their intended lifetime; they will need to be replaced with new technology to keep pace with smart grid efforts and to maintain reliability. That also means workforce knowledge and skill sets must keep pace with the ongoing technology evolution. There will be increased collaboration and integration with other information technology groups.

Developing an enterprise strategy for smart grid cyber security – As the grid becomes intertwined with more data and communications technology, it is essential that information is managed securely. SRP cyber security practices are primarily driven by general requirements and North American Electric Reliability Corporation (NERC) requirements. General requirements encompass standardization of technology components, interconnection of networks and devices, and the use of IP-based communication architectures that require application of cyber security best practices.
800.438.0790
NERC Critical Infrastructure Protection (CIP) standards provide regulatory requirements for cyber security. These standards define a minimum level of security requirements that must be applied to assets supporting the bulk electric system, along with audit processes for regulatory reporting and compliance. A formal policy has been developed based on National Institute of Standards and Technology measures/guidelines, and maintained to form the foundation of security practices. The policy drives implementation and provides the baseline for assessing compliance and risk, and will align with corporate policy and other departmental policies. SRP also is developing NERC CIP implementation plans for all critical assets. Groundwork for this stage was established in July 2008 when SRP began working with EPRI to create a smart grid “roadmap.” A leadership team supported by seven subcommittees with managers from various SRP departments was formed to oversee the process. In July 2009, SRP’s executive team approved SRP’s smartgrid roadmap. The roadmap comprises seven distinct strategies:

This includes developing cyber security, project execution, and metrics and benefits reporting plans that will use strategies identified within the smart grid roadmap. Because of this attention to detail, SRP received the Best Smart Grid Project Award by POWERGRID International magazine. SRP was honored for ingenuity, scope, practicality, vision and follow-through as a leader in the use of smart grid technology.
Meter Data Management System in the Works Currently, SRP is putting together a new meter data management system that will give the utility the ability to fully utilize all the data obtained from the smart meters and to tie the smart meter technology seamlessly into the SRP electric IT network. SRP recently announced it will deploy Elster’s EnergyICT EIServer ® meter data management solution to manage the Elster smart meters throughout the utility’s service territory. The EnergyICT ElServer deployment gives SRP with the network intelligence required to make more informed energy management and pricing decisions, enhance operational processes and deliver advanced customer services.
The MDM deployment will provide SRP with a number of operational benefits, such as work-flow management to integrate processes and data, improved sampling and expanded data options for load research, real-time data processing and demand response. Implementation should be complete in summer 2011. Mark Estes is a senior corporate communications strategist for SRP. He has almost 35 years experience in corporate and employee communications, and is an accredited member of the International Association of Business Communicators.
