HERE’S WHAT I THINK
the case for cleaner airports starts with renewables SURPRISINGLY, weather was blameless when a blackout delayed more than 1,000 passengers in Hartsfield-Jackson Atlanta International Airport in December 2017. A fire — later traced to a failed switchgear — was the culprit, knocking out the airport’s electricity for some 11 hours that day. The airport’s primary and backup power cables ran through the same tunnel and the fire destroyed both, leaving many travelers (including a good friend of mine) stranded and in the dark. This event came to mind nearly a year later when awaiting a flight at Amsterdam’s Schiphol International Airport, I read an article about The Netherlands commitment to clean energy — particularly at its airports. January 2018 marked a commitment by the country’s major airports (including Schiphol) to fully switch to wind power for electricity. According to the Royal Schiphol Group, which manages many of The Netherland hubs, local wind farms began supplying the company’s air terminals with a total of 200 gigawatt-hours of clean energy. What’s more: new wind turbines are planned for operation in 2020 to ensure an adequate power supply and the country’s train network also runs entirely on wind, a milestone reached one year earlier than originally planned. Impressive, right? Now imagine if North American airports routinely relied on renewable energy. A study by the National Academy of Sciences on the subject found that airports could benefit from onsite renewable sources by gaining greater control over their electrical infrastructure. For example, this means airport operations could function independently of global energy markets (a major plus for the travel industry considering airlines’ profits typically hinge on fuel prices;

read more at tinyurl.com/CleanAirports). Renewables may also serve as a source of backup power (which could have served Atlanta travelers), and particularly projects with hybrid battery storage. Certainly, a number of U.S. airports have installed solar panels (think Honolulu, Denver, Indianapolis, Tampa, and Tucson International has a unique “solar amphitheater” above its parking lots). In 2008, the Massachusetts Port Authority installed 20 wind turbines on the roof of Logan Airport’s offices, which use energy from wind along the waterfront. We can do better. If Fortune 500 brands and a host of other non-utility entities, including cities and universities, can buy a record amount of U.S. wind power in 2018 (according to the American Wind Energy Association’s latest Market Report), then airports and transportation companies in the country are wise to follow suit. Energy comprises a large portion of operating costs at airports and wind offers low, stable prices that are an incentive to buyers. In fact, the cost of wind has fallen by 69% since 2009, falling another 7% in 2018, according to investment firm Lazard. America is currently looking to the UK and Europe for lessons learn in offshore wind (see the article on page 26). Perhaps it should also look to The Netherlands for inspiration relating to renewables and travel and transportation. Speaking of clean-energy leaders, check out the companies our readers voted for as the frontrunners in wind leadership on page 36. Kudos to those wind and renewable workers and advocates diligently working toward a cleaner, more sustainable world. WPE

A global forum for offshore wind WELCOME the World Forum Offshore Wind (WFO), a newly founded not-for-profit association exclusively dedicated to fostering the global growth of offshore wind. According to the WFO, it will work with governments around the world to discuss and advance the key political parameters required to deploy offshore wind energy. This includes encouraging politicians to take action and introduce legislation that permits offshore wind farms. The organization was founded by nine international companies, which together, represent the offshore wind value chain. The Business Network for Offshore Wind, which represents over 200 member businesses in the United States, has joined the WFO. “Offshore wind has taken off in so many countries during the past two years, especially in the U.S. New markets are opening, and our success will depend largely upon global coordination and growth of the offshore wind value chain,� said Liz Burdock, president and co-founder of the Business Network.

WIND WATCH 100 for 100% renewables SKEPTICS SAID it was impossible. “We heard every version of ‘no,’ ‘can’t,’ ‘won’t,’ and ‘shouldn’t.’ We were laughed out of rooms,” shared Sierra Club’s Jodie Van Horn in an article called, 100 Cities Agree: 100% Clean Energy For All. (Read the full article at tinyurl.com/100CitiesCommit) Van Horn says it’s been three years since Ready For 100 launched, a Sierra Club initiative that pushes for the United States to commit to 100% renewable energy. The campaign is well underway, recently reaching a milestone: 100 cities and towns across America have officially committed to transitioning to 100% clean energy. Cincinnati, Ohio is credited as the 100th city to join the ranks of communities ready to fully commit to renewable power. “One in seven Americans — 48.7 million people, total — now live in a place committed to 100% clean, renewable energy,” writes Van Horn. That’s impressive and the Sierra Club and its members deserve full credit for the efforts as we work toward a country that’s powered by clean energy. A full list of the cities that have committed to clean energy can be viewed at sierraclub.org/ready-for-100/commitments

Putting training first
LAST FALL, the New York State Energy Research & Development (NYSERDA) released its “2018 New York Clean Energy Industry Report,” which found that over 151,000 workers were employed in the clean energy sector in the state. More than 5,600 jobs were added just in the last year and more are expected. In fact, the state announced $27.5 million in new funding for workforce development and training initiatives to help prepare New Yorkers for the clean energy industry’s growing job opportunities. With the growth of renewables — new data from the Federal Energy Regulatory Commission suggests renewable capacity could be quadruple that of fossil fuels by 2021 — education and training are essential. For example, in Georgia, Fort Benning Career Skills launched a new course last year to help
www.windpowerengineering.com
transition soldiers and veterans to jobs in wind power and other renewable industries. (Side note: According to the American Wind Energy Association, veterans find jobs in the wind industry at a rate of 72% higher than the average U.S. market.) With several U.S. offshore wind projects in the pipeline, the University of Delaware launched the first offshore wind skills training program in the country: the Offshore Wind Skills Academy. According to the University, the Academy will focus on the skills necessary to build a domestic industry such as permitting, environmental assessments, and local suppliers and vessels. In addition, a trio of Massachusetts-based institutions for higher education signed to Connect4Wind, with an aim of sharing resources and collaborating on the development of curriculum and programs centered on the offshore wind energy sector in the U.S. (Read more about this initiative in the article on page 26). The U.S. Business Network for Offshore Wind has a host of training events available at offshorewindus.org/training.

WIND WATCH How many wind turbines would it take to power the world? RESEARCHERS ESTIMATE that wind farms have the potential to produce up to 40 times the electricity the world consumes, but these projects currently provide only about 4% of the world’s electricity. However, improved infrastructure and higher voltage cables have drastically reduced the cost of wind power. It is predicted that by 2040, a third of global power will come from renewables such as wind and solar energy. A new infographic by RS Components, entitled, “How Many Wind Farms are Needed to Power the World's Major Cities?” shows just how many wind turbines are needed to power the top 25 global cities today. Tokyo takes the top

spot, with a total of 10,310 offshore turbines required, while Milan has the lowest amount at 238. To work out the number of turbines needed, each city’s annual energy consumption was divided by the amount of power the example turbine (the same one each time) can generate in a year. Data was compiled from the International Energy Agency (iea.org) and the European Wind Energy Association (ewea.org). Readers can go to tinyurl.com/WindPowersWorld, use the “sort-by” functions, and find your city (or the nearest one to it) to learn how many offshore turbines it would take to power your region.

WIND WATCH Meet the enhanced GWO training standards EVERY CONSTRUCTION SITE presents certain risks or hazards and this is particularly true of wind sites. Wind farms pose a safety challenge to techs and engineers because of the chance of falls and dropped objects. The harsh conditions typical at wind sites only heighten these concerns. Strong wind gusts or frigid temperatures can quickly and unexpectedly threaten a site’s level of safety. To mitigate such hazards, Global Wind Organisation (GWO) has been working diligently to promote and increase safety standards in the wind industry. GWO is a non-profit, member-based organization established by wind-turbine manufacturers and owners. Members collaborate by sharing evidence and risk information and, according to the GWO, this helps the industry “identify work activities where the creation
of standardized training can enhance safety for technicians and deliver various productivity benefits.” A worldwide network of certified training providers is essential to delivering GWO standard training. At the start of 2019, there were nearly 300 training sites in 37 countries. Just last year, 68 new sites opened, including three new training facilities in the United States and one in Canada. An additional six U.S. training sites are expected to gain certification over the next 18 months as the country’s supply chain gears up for offshore wind on the Eastern Seaboard. GWO recently released its 2019 work plan that includes several enhanced “task specific” training standards. “Our work plan in 2019 is agreed upon by 16 leading global companies that are the world’s largest employers
GWO members developed the Basic Safety Training Standard in 2012 and today more than 70,000 people, including over 1,000 Americans, have received the training. The organization’s new Blade Repair Standard is scheduled for release in April of this year. Learn more at globalwindsafety.org

WIND WATCH in wind energy,” said Eloy Jauregui, Chairman of GWO and Safety Director of Acciona Energia. There will be a mixture of projects reaching completion — like the Blade Repair Standard.” Jauregui refers to the wind industry’s first global training standard for blade repair technicians, set for release on April 1, 2019. The GWO Blade Repair Standard Working Group is currently pilot testing the training, which aims to align the training programs of different manufacturers and deliver a standard benchmark of skills for blade inspection and repair technicians. Another priority for GWO is aligning its standards with other similar training programs in the industry. For example, it has already completed this process against entry-level wind technician trainings from its members such as Vestas Service D and Siemens Level 1-4. Thanks to a short ‘gap training’ session, techs who’ve earned one of those manufacturers’ training can receive a GWO Basic Technical Training standard certificate, which is recognized by all 16 members of the organization. “All GWO training can be merited against similar training by using gap analyses,” explains Jakob Lau Holst, CEO of GWO. “This identifies how similar the training is and if there are any gaps where the existing training needs to be 'topped up.’ On the other hand, a training course could deliver all the learning objectives of a GWO standard already and the technician deserves a GWO certificate.” The important thing, explains GWO, is that standards are about comparing apples with apples. “We are speaking with organizations across the United States, such as labor unions and other training bodies who already deliver courses,” says Lau. “If their training can be compared to a GWO
WINDPOWER ENGINEERING & DEVELOPMENT
windwatch - WPE 02-19 - v6 FINAL.indd 11
standard and the differences ironed out, it will benefit everyone because we all recognize the same thing.” The final piece of the puzzle at GWO is the way certificates are awarded and stored. Certified training providers upload them to WINDA, the wind industry database. WINDA then helps employers verify the status of GWO-certified training providers and the training status of delegates who have attended GWO training courses. Information about WINDA is available at globalwindsafety/winda.

Wind work around North America There’s good news for 2019. According to a new report from the U.S. Energy Information Administration, new electric generating capacity will primarily come from wind, solar, and natural gas. What’s more is that nearly half of the utility-scale capacity additions will consist of wind power (at 46%). Currently, about 10.9 GW of wind capacity is scheduled to come online in 2019 though most will start operations closer to December. Three states will take the majority of the credit and be home to more than half of the year’s planned wind capacity additions. Congrats, Texas, Iowa, and Illinois.

INVESTMENTS
Offshore wind projects provide unique challenges for developers relating to environmental and siting regulations, offshore transportation and worker safety, weather conditions, and wind-farm uptime. It is important to seek the advice of a qualified underwriter to mitigate project and insurance risks.
A Q&A WITH SENIOR UNDERWRITER, JONNY ALLEN
Insuring offshore wind farms:
What developers need to know
OFFSHORE WIND is quickly gaining momentum in the United States. The last year brought a wealth of new news stories related to offshore auctions and state commitments to developing wind farms, particularly in the Atlantic. Although the focus has been on siting and environmental permitting, one critical aspect of new wind project development is insurance. Offshore wind turbines are at greater risk of component failure and downtime compared to landbased turbines because of the stronger winds, higher moisture, and harsher conditions at sea. There are also risks to wind technicians and workers requiring vessel trips to and from a project site, which presents additional challenges — such as the taller towers

typical of offshore wind turbines and less stable platforms when moving from vessel to turbine. To answer questions related to insurance and offshore wind, we spoke with Jonny Allen, Senior Underwriter and Head of Offshore Wind at Travelers, a global insurance company. Here Allen shares his insight on the industry based on his years of wind experience in Europe. Q. What considerations should project developers give to insurance for offshore wind projects? A. Each offshore wind project brings unique challenges and complexities based on several factors including size, scope, location, and type of stakeholder. We learned early on that the offshore wind claim process is different from that of onshore wind, particularly given the marine element.

When something goes wrong, there can be several potential root causes and pinpointing which one caused the loss can be difficult. For this reason, it is critical to have a solid insurance policy in place. This is partially why the role of an underwriter is so important. Underwriters understand the industry, claim process, and coverage options, and can work with customers to make sure their specific issues and needs are addressed while helping to mitigate risk. Q. As interest in offshore wind grows in the U.S., what are some of the biggest challenges you foresee? A. Some of the biggest challenges we see relate to factors like scaling technology, construction methods, geography, climate and weather, natural disasters, regulations, and conservation policies. Some of the more significant challenges include: • Wind events: Parts of the U.S. experience hurricanes, a weather-related scenario the industry has yet to face. As such, there is a lack of modeling to pull from or consensus on data because these geographic areas are newcomers to offshore wind. No one fully understands how wind turbines can stand up to those heavy winds in the U.S. Will a typhoon-class turbine work in hurricanes, or will further design changes be necessary? While the wind season is relatively defined in the U.S. and a developer could plan to install turbines outside of that timeframe, what happens if a project is delayed? • Local content: In the U.S., many questions remain for the industry. For example, will future offshore wind projects have workarounds, such as using non-U.S. vessels to perform installations and U.S. vessels to ship items to the site? Will the country build its own specific vessels or be granted waivers to the Jones Act? How will the inland transit of large items be handled? Finding a balance between cost-effectiveness and stimulating the economy is important. • Contractor experience: Experience is an extremely important factor when selecting a contractor but finding one can be challenging in an emerging territory. While Europe has contractors that are specific to offshore wind, it did not begin this way. The U.S. will have to decide carefully on an approach: work with smaller contractors with specific offerings or established energy operators that are adapting their existing offerings for offshore wind installations?

Q. How might local supply-chain requirements for offshore wind projects impact insurance risk? A. While the demand for minimum local content supports development, it’s important for offshore developers to balance cost-effective procurement with project risks. We have seen claims as a result of inadequate supply chain factors such as poorquality materials, inexperienced subcontracting, and incorrect transport and storage. Underwriters would rather charge less to support a project if risk management through quality supply and contracting can be demonstrated at all levels. Underwriters can help with this by communicating what this can look like well before the project breaks ground. Q: What’s driving the increase in turbine size and how does it impact insurance? A. Today, we’re seeing wind turbines six to nine megawatts in size, some of which have a wingspan the size of the London Eye. In the next five years, capacity will more than double to 15 to 20 megawatts, with tower sizes that exceed 250 meters. Larger rotors harvest greater wind energy and can reach stronger, steadier winds at higher altitudes. Bigger turbines can produce greater outputs and maximize ROIs. Additionally, such projects can use fewer turbines, which can result in shortened, cost-effective installation timeframes. However, the growing size of turbines is leading to engineering challenges and new insurance considerations, including larger limits and additional exposure. For example, taller towers and bigger blades are more difficult to transport and install, requiring specialized vessels and crew. For some offshore projects, this can also mean engineering plans that are costly, projectspecific, and dependent on a single piece of equipment (such as a specialized vessel or crane). If lost or damaged, this can cause major delays. Moreover, insurance companies have little data to project how these turbines will stand up to major windstorm events.

Q. Are there lessons that can be learned from the windfarm installations in Europe? A. Absolutely. The U.S. wind industry can benefit from understanding how Europe has dealt with technological challenges, offshore turbine installations, cable and power transmission issues, and costs. Consider a German model, for example, which clusters multiple project sites and uses a separate company to provide the transmission networks for the wind farms back to the main electric grid. This encourages competitive bidding for wind projects and reduces risk by removing the requirement for each developer to build long and costly grid connections for each project. Interestingly, many of the problems encountered in the industry’s early days are still prevalent 10 years later. Given the inherent complexities of offshore conditions and the composition of the seabed this makes sense. It also means the lessons that have been learned to date are vital as the industry continues to grow and develop. Q. Any final tips for choosing an insurance plan? A: Choose an insurer with experienced offshore wind underwriters who have spent time in the field, going on to vessels and up turbines, speaking with people involved in the projects and getting to know the assets they’re insuring. Underwriters that truly understand the business of wind energy can help developers find the right balance of coverage based on their specific needs. WPE

ground rings WHILE THE PROMISE OF OFFSHORE WIND is grabbing many headlines of late, it is onshore wind that is currently producing the majority of the renewable electrical energy in the United States. For the most part, onshore wind turbines are set at capacities of two to three-megawatts, meaning component reliability is key to production. Given the harsh conditions in which turbines operate, this is typically easier said than done. Therefore, it is important to ensure all turbine components are subject to regular operations and maintenance checks — including for small devices, such as ground rings and brushes. Understanding ground rings One operational challenge onshore wind operators face is the phenomenon

of ground-ring grooving. Wind-turbine ground rings help divert powerful shaft currents, which may reach 60 amps/1,200 volts or even higher. Their core function is to prevent damage to bearings and other equipment. Ground rings work by transferring current through the use of brushes, which are typically held in contact with the ring with a constant force spring. This means that as long as there is contact, the current will be diverted effectively. The brush is an electrical conductor that works with slip rings and brush holders, protecting vital components from parasitic currents and static electricity. Worn or low-quality brushes can wear on a slip ring, causing it to degrade prematurely or force early component replacement.

In addition, wear and tear may result in misaligned shafts and components — which also cause wear on components. For example, brushes may become misaligned and lose contact with the vibrating slip ring. Unfortunately, it takes little movement for this to occur and even a variation of one or two degrees can impact proper function. If this happens, the air gap between the ring and brush causes a high inductance of the circuit and arcing electrical currents will slowly erode the metal. This leads to grooves in the slip ring and, occasionally, may affect the bearings, too. As the metal erodes and grooves deepen, it creates a growing gap between the ring and holder, causing greater instability between the slip ring and brush. This effect has several

The WTG1 brush box holder form Morgan Advanced Materials are manufactured from aerospace -grade materials. The radial mounted brush holders eliminate friction chatter that occurs when brushes are placed in a stubbing or leading orientation. Constant force springs deliver equal and proper brush pressures for a low wear differential from brush to brush.
An arcing risk Arcing has the potential to cause far more damage than reduced ground ring effectiveness. When metal erodes, the result is a sandpaper-like surface with fine dust particles layering the brushes. This dust contains conductive material (carbon and copper), which may cause a current to flow between phases or phase to ground. This may lead to a destructive flashover or, even worse, an electrical explosion. The result: catastrophic damage to the wind turbine. Damage to the turbine components must then be assessed and repaired. For example, the slip ring may require

A FEW IDEAS WHEN REPLACING GROUND RINGS It’s rarely possible to replace ground rings up-tower. Typically, the entire slip ring assembly in a wind turbine requires removal to access the ground ring. And slip ring assemblies are extremely heavy, often in excess of 200 lbs (75 kg). Proper lifting equipment and at least two technicians are necessary. Clear safety precautions are a must to avoid worker injury and equipment damage. Ensure techs are properly trained and employ well-fitted, quality fall-protection gear. This is a given but never risk personnel safety to save costs.
re-machining in-situ or offsite repair. Failing that, replacement is necessary at the cost of up to $5,000 per ring. If new bearings are needed, expect a cost of between $5,000 and $10,000 each. What’s more: when brushes lose contact with the ground ring, costly damage to electrical equipment and circuit boards is likely. And a single day of downtime represents an estimated $1,500 in lost revenue. To reduce the likelihood of such a destructive event from occurring, wind operators typically use a brush holder that accommodates two brushes — covering some 40° (1/9th) of the ring. The idea is that if one brush loses contact, the other works as a failsafe. However, in practice, this creates a ‘bouncing’ effect between the two sideby-side brushes — called friction chatter — and causes both to lose contact simultaneously. In addition, brush holders come as fixed and unmodified devices and are generally placed a fair distance from the ring, which does little to fix the problem.
g
An adjustable idea A new idea to reduce slip ring and brush wear uses a fully adjustable drop-in replacement ground brush holder system. Instead of two brushes,

To prevent slip-ring damage, consider using a durable rubber mat as a protective surface for the ring. For example, the mat can be used to protect the new ring in the lift bag while transporting it up-tower. It can also be used during the transitions from the yaw deck to the nacelle, and again as the ring is moved within the nacelle and into position on the generator shaft. After the slip ring and holders are removed, take the time to thoroughly clean the slipring compartment. Removing all brush dust and grease is the best way to prevent early contamination in the new slip rings and brushes.
this new invention deploys four within the same mounting space. This means upgrading is straightforward and simply involves unbolting and removing the old brush holders, and bolting in the new one. These brushes are durable and manufactured from aerospace-grade copper graphite material. The material is specially treated to withstand low and high humidity environments, and forms a low friction film or patina on the slip ring. The low-friction film reduces friction chatter (the ‘bouncing’ of the brushes) and dusting, and extends the brush life. Additionally, the proprietary treatment is not a sticky resin so, if dust occurs, it is unlikely to collect or stick, making brushes easier to clean. The carbon holders are also fully adjustable to increase the distance between brushes and improve stability and contact. This gap provides up to three times the coverage of the typical OEM design in a turbine. Other features include quick disconnect brush terminals for

simple maintenance or replacement. The unit cost of this new brush holder is also significantly lower than for a replacement ring or bearing, and particularly when turbine downtime is considered for component repairs. Reliability is critical in wind applications that must withstand harsh conditions. A word to the wise: consider wind-turbine components carefully, even the small ones, and mitigate the risk of wear whenever possible. WPE

and particularly in California where land is scarce and property values are sky high?

SIX FACTORS TO CONSIDER BEFORE REPOWERING A WIND SITE
RECOMMENDATIONS FOR REPOWERING Prior to committing to repowering an older wind site, consider this checklist. •
Identify local and regional zoning and permitting requirements for a wind project, including restrictions on property, public rightof-way, as well as visual and safety setbacks.
•
Assess and determine which new turbine technology will conform to the proposed site.
•
Model the legacy operating wind data.
•
Confer with the Department of Defense.
•
Submit the turbine coordinates to the Federal Aviation Administration.
•
Undertake “Phase I Environmental Site Assessment.”
•
Evaluate the feasibility of operating the project through the remaining Power Purchase Agreement (PPA) term and compare the results to repowering the current wind turbines.
•
Review real-estate agreements to determine suitability for repower and economic impact of regeneration or extension.
•
Identify new potential off-takers and negotiate a new PPA.
•
Model the feasibility and suitability of hybrid technologies.
may mean replacing several windturbine components and turbines, or the full fleet of turbines and towers at a site. Additionally, repowering may modernize interconnection infrastructure, construct or redesign new roads, or add more turbines to the project. Typically, the aim is a wind farm with a greater and more efficient generating capacity than before. Using California as a model, there are many considerations that may impact the development of a repowered site. Here are six important factors to assess or contemplate prior to moving forward with a repower project. 1. Changes in national or local laws and jurisdictions Projects developed in the late ’80s and early ’90s are now subject to changes in laws and regulations affecting local and regional jurisdictions. Previously, certain jurisdictions permitted projects in parts, under separate departments. For example, a developer may have consulted with several different authorities at the federal, county, or city level for permitting of safety setbacks affecting turbine height approval.
However, this required simultaneous consultation with different entities and meant that a developer must then synthesize these conditions into the site plan for the Conditional Use Permit (CUP). A CUP grants use of land in a particular area for permitted construction. Fortunately, some entities have since formed coalitions to streamline the compliance process. Riverside County is one example where the Bureau of Land Management, City of Palm Springs, and County of Riverside developed a comprehensive process for defining and subscribing to visual and safety setbacks. When evaluating the value in repowering a wind project, careful review of current requirements and restrictions in local jurisdictions are imperative to ensure the new plans are lawful. Legal changes can also affect the timeline and costs for a repowering project, particularly if a developer is hoping to take advantage of incentives, such as the Production Tax Credit (which expires in 2020).

2. New wind-turbine technology Turbine technology has dramatically improved over the past 20 years. The result: the average capacity factor (a measure of power-plant productivity) for wind turbines installed before 1998 was about 22% and today it’s at nearly 35%, according to the Office of Energy Efficiency and Renewable Energy. In addition, wind energy costs have decreased from a little over 55 cents (current dollars) per kilowatthour (kWh) in 1980 to an average that is under three cents per kWh in the United States today. Lower costs and increased efficiency are providing developers with important incentives for monetizing repowered projects. 3. Contract structure of real property agreements A detailed review of the project’s original site control documents is another important step to identify limiting or restricting factors that may affect a repowering project. For example, an existing contract may exclude property that is pertinent to new turbine additions or contain prohibitions on road restructuring. In addition, any lease term in California that exceeds 35 years is considered a “beneficial transfer of real property,” according to the local assessor, which may result in hefty additional real property taxes and assessments. Typically, wind lease agreements require the developer incur the cost of assessments relating to new installations or site improvements. So this cost must be quantified and accounted for over the term of a project in the repower project financial model.

TO REPOWER OR GREENFIELD? A greenfield is a new wind project on land that’s previously undeveloped and without a permit. One of the first steps of a greenfield development is an assessment of the local permitting agencies to determine the likelihood of a new wind project. This process should include a thorough review of the requirements to determine restrictions that may impede new project plans, such as permitting risks (think: safety, visual, or viewshed setbacks). Timing is also a critical factor for the start of project construction and delivery of power to a utility off-taker. Early assessments of potential schedule delays or unexpected costs are critical to project success. Another early make-or-break factor of a new wind project is local community support. For example, the first meteorological tower at a project near San Diego County, California, took 12 months to permit and install at nearly $1 million. A met tower is a wind measurement device used to determine project siting and turbine placement. In this case, the met tower required an administrative permit necessitating an extensive public relations push, including community presentations and a vote by the county board of supervisors. One advantage of a repower project is that it’s typically safe or “de-risked” from community and jurisdictional concerns because the wind farm already exists. Therefore, legacy operating and existing wind data can mitigate many of the principal challenges facing developers on a repowered development project.
4. Environmental and permitting considerations Depending on the location and ownership of the project property, a series of agencies including federal, state, county, water authorities, Bureau of Indian Affairs, may have the right to exercise jurisdiction over the project. For example, the California Natural Resources Agency is one of many agencies that oversee and enforce environmental and permitting regulations throughout California. Turbine size may also affect the permitting regimes. Larger wind turbines, for instance, use more space and may require additional compliance steps and approvals. The Federal Aviation Administration (FAA) maintains jurisdiction over the location of wind-turbine locations and improvements. It is important to prepare a pre-submittal of the proposed turbine locations to the FAA for clearance prior to (or concurrently with) permitting and environmental review of the project. Similarly, the Department of Defense (DOD) imposes jurisdictional

requirements over wind projects so a preliminary discussion with the local DOD office is recommended as a gating item in the initial review of the wind project and turbine locations.
According to a 2017 Energy Information Administration report, repowering can increase wind turbine fleet output by 25% and add up to 20 years to the life of the turbine.
5. Power purchase agreements or PPAs Wind projects are typically developed with 15 to 20year PPA terms. Repower projects are often facing the end of their initial PPAs — the document that states the underlying revenue stream and financial security for the project. For this reason, careful consideration and implementation of a viable strategy are necessary for operating the wind project through the expiration of its PPA term. Additionally, redevelopment of the wind farm, which may require a new design of the project and decommissioning of the existing wind turbines, means new negotiations or agreements. To properly evaluate the economic impact of early decommissioning of the wind turbines or running the turbines through the entirety of the PPA term, feasibility modeling is highly recommended. Together with the expiring PPA, consideration must be given to the negotiation of a PPA with the existing off-taker or a new one. Many alternatives are available for PPA’s today that were previously unavailable, including hedge arrangements and corporate PPA’s with off-takers such as Facebook, Starbuck’s, Google, and General Motors. 6. Integration of hybrid technologies Hybrid renewable projects are now an option for many developers. Pairing wind with solar or battery storage may enhance and improve the economics and reliability of such projects while providing greater energy generation efficiency. Although battery storage is still in its infancy, it can reduce concerns relating to the variability of wind power — storing energy when winds are strong and providing power to balance the grid when winds are low. Storage is likely to become a key consideration for developers looking to maximize revenues and generation flexibility when repowering wind farms. WPE

wind success
One way the U.S. offshore wind industry can optimize project developments and better ensure ROIs is to learn from the experience of others — and that’s precisely what those spearheading the offshore sector in the country are doing. Europe and the UK are decades ahead in offshore wind, so the United States is seeking advice, lessons learned, and success stories from overseas to better ensure a smooth start.

he Humber, UK is quickly becoming the benchmark location for offshore wind. A large tidal estuary on the east coast of Northern England, the Humber offers a significant hub for wind development and marine experience that essentially spans the full lifecycle of an offshore wind farm. And while the region is serving the United Kingdom and Europe quite well, those working in the industry are more than willing to share their lessons learned and expertise. “It’s the envy of the world,” shared Ray Thompson, Head of Business Development with Siemens Gamesa, at an Offshore Wind Connections conference in Hull last year. Ports on the Humber include the Port of Hull, Grimsby, and Immingham. “Ten years ago if you wanted to see how the wind

industry worked you went to Bremerhaven in Germany. Now everybody wants to come to Hull to see how it’s done.” Indeed, the region has paved the way for Ørsted’s Hornsea Project One (the world’s first offshore wind farm to exceed 1 GW) and Project Two, and others such as the 860-MW Triton Knoll that began construction in 2018. In fact, Ørsted currently employs some 350 workers at its rapidly expanding East Coast Hub in Grimsby. Siemens UK also invested heavily in its windturbine production facility at the Alexandra Dock in Hull, which is proving invaluable. A 2017 report released by trade organization, RenewableUK, found that UK-based companies provided nearly 50% of the total content of British offshore wind farms and that the country was exporting turbine-related components to countries such as China, India, Taiwan, and the United States. However, organizations such as Team Humber Marine Alliance (THMA) are ensuring more than just components are sourced from the UK. “To maximize the huge potential of offshore wind, globally, it takes great collaboration,” says Mark O'Reilly, CEO and Chairman of THMA. The Alliance is a collaborative UK-based membership organization that works to support, educate, and facilitate work within the marine, maritime, and offshore wind sectors. “Our aim is to bring together governments, industry, academia, and training to ensure proper accreditations and effective supply chains for a successful offshore industry across the world,” adds O'Reilly. In fact, THMA organized the Offshore Wind Connections conference in Hull and was part of a delegation that took part in the New Bedford Offshore Wind Symposium in late 2018 — with a focus on a UK and U.S. collaboration. Those delegates also visited New York and New Jersey to answer questions and offer guidance to local wind leaders, including government. “There is enormous interest from organizations and at the state level in the United States about how the Humber and other offshore wind hubs in the UK have overcome offshore challenges, such as environmental, educational, and supply chain ones,” says O’Reilly.

Building a skilled workforce The U.S. Department of Energy estimates some 43,000plus new jobs will come from the offshore wind market by 2030. This is good news for the economy and job force, however, adequate training is essential — and particularly in the U.S., which only has one five-turbine offshore wind farm to date. “Like any new industry, it’s a blessing but there are challenges,” suggests O’Reilly. “The offshore wind industry is a tough one given the stringent environmental and manufacturing standards, and the harsh marine conditions. Typically, at least for wind techs, it’s not a 9-to-5 gig either.” However, there is diversity in the sector, which opens the market up to many fields, he adds. “For The U.S. could tap into a vast offshore wind energy resource and better steward its marine environment by galvanizing large -scale research and example, when Siemens UK opened its blade fostering public-private partnerships, according to a report by POWERmanufacturing plant in Hull, nearly 800 production US.

According to the University, the new Offshore Wind Skills Academy will focus on the skills necessary to build a domestic industry such as permitting, environmental assessments, and local suppliers and vessels. “The northeast states in the U.S. have committed to 10,000 megawatts of offshore wind to be built in the next 10 years,” said Willett Kempton, a new director of the Offshore Wind Skills Academy, in a recent press statement. “That is the equivalent of building an entire nuclear power complex each year for the next 10 years.” Meeting this demand will undoubtedly require significant effort by American companies interested in entering the offshore market and global offshore wind companies learning about operating in the U.S. “Establishing a new industry takes drive, initiative, and the people to push it forward and support it,” says O’Reilly. “Given our time in the U.S. with the Alliance, I’ve seen that in the country already. I think the U.S. will do well.” Drawing from experience One reason O’Reilly predicts a successful offshore wind market is its openness to support. “It's all about collaboration,” he says. “The Alliance encourages partnerships and joint

ventures because often times that’s how a sector overcomes challenges and advances.” He points to the strict offshore and environmental rules in the UK as one example. “Authorities such as the Marine Management Organization have been willing to support offshore wind developers so they can better understand and meet permitting laws.” The United States is following similar footsteps. Last year, the U.S. Department of Energy awarded the New York State Energy Research and Development Authority (NYSERDA) $18.5 million over four years to establish a public-private consortium tasked with developing cost-effective, efficient methods for offshore wind installation, supply chain challenges, and O&M. The consortium already launched its first roadmap aimed at accelerating the deployment of offshore projects. “The key is finding companies with complementary services and getting them to work together to foster opportunities that may have been lost without that relationship,” says O’Reilly. “It's a bit like matchmaking, connecting individuals and organizations, and then seeing what comes from it.” A new report from the Partnership for Offshore Wind Energy Research (POWER-US) also finds that collaboration is one step to advancing the offshore industry in the U.S. The study says that the country could tap into a vast offshore wind energy resource and better steward its marine environment by focusing on large-scale research and fostering public-private partnerships. It notes that public investment in research and strong connections between academia and industry are what helped advance

offshore wind energy in Europe. Additionally, it describes how large-scale public support and the convening of complementary expertise were critical to the success of other large-scale U.S. scientific and engineering initiatives, such as earthquake simulation, oceanography, and materials manufacturing. According to the report: “The emphasis on ‘convergence’ highlights the importance of a collaborative approach, bringing together expertise from a wide range of disciplines, including engineering, atmospheric science, logistics, economics, environmental science, and local communities and the marine industry, including fisheries.” “Working with the fishing industry is another example of collaboration,” says O’Reilly. “I believe the U.S. is currently in talks with the fishing industry to ensure minimal impact and reinforce the opportunities to work together.” Indeed, offshore wind developer, Deepwater Wind (acquired by Ørsted in November 2018) adopted a firstof-its-kind procedure to prevent impacts to commercial fishing gear
from offshore wind energy activities. The procedure was developed with the commercial fishing industry and accounts for feedback from Atlantic coast fishermen. Deepwater Wind determined that keeping fishermen informed is the key to preventing damage to fishing gear, and has included a process for gear loss and damage claims. The Responsible Offshore Development Alliance has also partnered with Ørsted with the goal of improving communications between the commercial fishing industry and offshore wind developers. It offers an unprecedented opportunity for those who fish commercially to provide direct input to the wind industry on matters of interest to their business. A core component of the partnership will be the creation of a joint industry task force to explore improved approaches to fair project siting, design, and operations. “It’s really common sense,” shares O’Reilly. “Proper communication, collaboration, and education are bound to lead to a more successful outcome — and, in this case, industry.” WPE
Deepwater Wind was the first American wind developer to adopt procedures to prevent impacts to fishing gear. The offshore wind company was acquired by Ørsted in late 2018.

A wind tech’s guide to
dropped-object
prevention Learning the “Three T’s”
WIND-TURBINE TECHNICIANS face the challenging task of climbing a couple hundred feet or more uptower and safely transporting the tools required for working atop their towering workplace. This is typically done with proper tethering to ensure tools are securely fastened to a tech’s body while climbing and working at height. Dropping objects from atop a 250-foot turbine tower carries plenty of risks. The greatest hazard is an injury to workers on the ground. A corner of the manufacturing industry has developed fall-protection products to keep tools secured, however, there has been a lack of enforceable standards for drop prevention while laborers work at heights. Fortunately, last year brought new standards for dropped-object prevention. Although these regulations

are voluntary, they represent a step forward in the safety industry. To ensure tools and gear travel securely up and down wind-turbine towers, there are also three simple rules — known as the “Three T’s” — that wind techs can follow to avoid dropped objects while working up-tower. The standards In July 2018, the International Safety Equipment Association enacted the American National Standard for Dropped Object Prevention Solutions (ANSI/ISEA 121-1208), which, for the first time, created standards for manufacturing and testing equipment meant for drop prevention. The new standard is a step forward in the safety industry, but a voluntary one. “It takes tool tethering from duct tape and rope, which most [workers]
www.windpowerengineering.com
are using out there, to engineered solutions that are that are safer to use,” says Nate Bohmbach, product director at Ergodyne, a developer of safety gear for construction and industrial workers. Until now, there has been little guidance for workers on what constitutes a proper tethering system. Bohmbach points out that without a set standard, there is nothing to differentiate duct tape and string from a properly rated tool lanyard and attachment point. “The new standard formalizes tethering as a best practice,” he adds. ANSI/ISEA 121-2018 also establishes minimum design, performance, testing, and labeling requirements for dropprevention products. Ergodyne backed the new safety standard with international manufacturing company 3M. Bohmbach

says it provides a rule sheet for the manufacturers designing dropprevention products and the workers using the gear. “Now that we’ve led the way to develop this standard, our full attention is on helping workers understand what it means and how it can help them,” says Bohmbach. To this end, Ergodyne employees have authored “The Three T’s of dropped objects prevention.” The three T’s stand for trapped, tethered, and topped. They are modeled after the ABC’s of fall protection. • Anchorage: Attaching a lifeline to a secure point. • Body support: Wearing a body belt or harness. • Connecting device: The device, often a lanyard, which connects body support to an anchor point. “It’s not just dropped-object prevention, Bohmbach says. “It’s safely managing your equipment to and from the work site and while at heights, and dropped objects is a huge part of that.” The three T’s By Ergodyne’s definition, trapping means to secure a tool with a retrofitted attachment point meant for tethering it to an anchor. This can be done with sleeves, slips for screwdrivers, brackets and wraps, or other attachments installed with tape and string.

Fatalities caused by falls from elevation continue to be a leading cause of death for construction employees across industrial sectors, according to the Occupational Safety and Health Administration (OSHA) in the U.S. Consider hosting a Safety Stand-Down at your company, a voluntary event for employers to talk directly to their workers about safety. OSHA’s National Safety Stand-Down raises fall hazard awareness across the country in an effort to stop fall fatalities and injuries. In 2019, it takes place from May 6 to 10. Learn more at osha.gov/StopFallsStandDown
Tethering tools with a lanyard keep them secured to an anchor using a carabiner. Ergodyne carries lanyards that come in different lengths, including a coiled model that stretches. Equipment can also be carried up a wind turbine using a topped bucket, bag, or pouch. Ergodyne’s topped products have tethering points and covers to keep contents from spilling out if inverted. Although dropped objects and fall risks are two different hazards, one can lead to the other. “The obvious drop risk is an object striking somebody below. That’s why you prevent dropped objects,” he explains. “But we also teach in our training that this protects workers at height as well. A dropped object can lead to somebody trying to overexert and grab something that they've dropped, and it can throw them off balance and lead to a fall.” Bohmbach compares this reaction to catching a pen that’s rolling off a desk. Now imagine accidentally losing grip on a cell phone or wrench when atop a wind turbine. A similar reaction could result in an injury or a fatality. Technicians typically carry hand tools, power tools, and monitoring devices, such as iPads, up turbines. Each of these items should be fastened to a technician or held inside a topped container. Any loose object is at risk of dangerously falling to the ground or inside the turbine and causing equipment damage.

Typically, the objects that fall during work done while at height are not tools but items such as smartphones, tables, or keys. These objects should be stowed safely away in pouches that zip close and attach to carabiners through a steel ring.

“Anything that will help a climber keep his hands free and those tools tethered — basically our whole line could apply to wind power,” shares Al Buczkowski, marketing communications manager at Ergodyne. The company field tests products for about a month before bringing them to market. The drop-prevention gear is given to a trusted technician and used on a work site. “It's really just listening to that end-user. They’re the ones that know the problems and it's having a direct line with them,” Bohmbach adds. “Techs are gear junkies. They know what's good and what's bad; they know what's going to work and what's not going to work; and they love actually getting their hands on new stuff and trying it out and that's with any of our products, not just dropped object stuff.” WPE
Power and hand tools should be secured by attaching a carabiner to a connection point on the tool. The lanyard is then anchored on a worker’s person or another stable point at the worksite. Look for protection products that are thirdparty tested in harsh conditions.

THE YEAR AHEAD promises new growth and exciting challenges for the wind industry. Over 20,000 MW of new wind capacity was already well under construction near the end of 2018, with another 17,000 MW in advanced development. According to the American Wind Energy Association’s (AWEA) Market Report, seven states were close to doubling wind, bringing the total capacity of wind in the United States to more than 90,500 MW. What’s more is the low cost of wind. In a recent study from research firm, Lazard, wind is now the cheapest source of new power generation in many U.S. markets — and that’s regardless of incentives. Wind is, for the first time, also becoming costcompetitive with existing conventional power plants. Lower costs are leading to increased demand and new, more efficient turbine components and towers. For example, 2018 saw the first orders for 4-MW land-based wind turbines from turbine manufacturers such as Senvion and Vestas. GE also promises the first prototype of its Haliade-X offshore wind turbine in 2019, featuring the world’s first 12-MW capacity. Flip through the pages of this issue and you’ll get a sense of

the innovation that permeates the wind industry. The U.S. offshore industry has also fully launched with more offshore wind farms to begin construction in the coming years. In fact, The U.S. Department of Energy predicts about 22,000 MW of offshore wind is possible by 2020 and states such as Massachusetts (1,600 MW by 2027), New York (2,400 MW by 2030), New Jersey (3,500 MW by 2030), and others have already set lofty offshore wind goals. And because U.S. waters are deeper than the North Sea, expect to see a few floating wind turbines. California has already proposed a 100 to 150-MW floating offshore wind farm more than 20 miles off the coast of Eureka.

Like all Aurora Bearing spherical bearings, the LCOM series features a one piece steel raceway, swaged around the ball for a smooth, precise, close tolerance fit, along with the benefit of the strength and vibration resistance of steel. In addition, this series is optionally available with Aurora’s proprietary AT series PTFE liner, for a zero clearance, self lubricating fit. Aurora LCOM Spherical Bearings were designed to offer a higher level of performance with dimensional interchangeability for the “LS” spherical bearing category; a market segment which has remained largely unchanged since the 1950s. “LS” bearings are characterized by being of 3 or 4 piece construction, with an inner ball, an outer ring, and a one or two piece brass, bronze, or copper alloy race between. Since the early 1950’s users of these bearings, which are also marketed with a “FLBG”, “RS”, or “VBC” prefix, have had to accept their low strength and poor vibration resistance due to the low strength race material. Aurora’s LCOM bearings incorporate superior materials and manufacturing processes to overcome the performance deficiencies associated with “LS” bearings.

Metric spherical plain bearings built to DIN ISO 12240-1 (formerly DIN 648) schedule K often are made with inner races or rings made of brass, bronze or copper. For many low demand applications these bearings have proven to give satisfactory service. However, in applications with high loads or high vibration levels or both, the bearings can quickly develop excess clearance due to a deformation of the relatively soft race material.
www.windpowerengineering.com
This weakness is addressed in the Aurora Bearing Company’s COM-M series spherical bearings. Like all Aurora inch dimension spherical bearings, these metric bearings all feature a 1 piece steel raceway, cold formed around a chrome plated, alloy steel ball for strength, precision, and structural integrity. Aurora COM-M series bearings are available in sizes from 3mm to 30mm., and follow the dimensions of DIN 648 schedule K. Bearings are optionally available with Aurora’s self lubricating AT series ptfe liner, for a smooth, zero clearance fit that is self lubricating and maintenance free.
Maintenance free & corrosion resistant rod ends from Aurora
The Aurora CM/CW-ET series rod ends offer a combination of features unique in the rod end industry. Instead of the low strength steels typically found in stainless rod ends, the ET series features bodies made from heat treated 17-4PH material. Not only do they offer excellent corrosion resistance compared to conventional rod ends, they provide greater load capacity, strength, and durability as well. The ET series comes standard with Aurora’s exclusive AT2100 PTFE liner. This, combined with a heat treated 440C stainless ball, gives a durable, zero clearance, self lubricating, maintenance free bearing interface to go with the benefits of the heat treated body. Their two piece design allows exploiting these high performance features to be exploited at an economical price. The Aurora ET series bearings can be used to enhance the performance of equipment in wash down, marine, and other environments that require extra corrosion resistance.

As the power output requirements increase for wind turbines, wind generator manufacturers are moving towards larger blades to rotate these larger turbines at lower wind speeds. As the wind blades increase to over 45 meters in length, blade construction is moving away from the more traditional all fiberglass construction to utilize more carbon fiber. The carbon fiber provides a substantial weight savings and increased strength to combat the extreme stress loads exerted on the blades during operation. Carbon fiber, however, is conductive and more prone to be struck by lightning. Without proper protection, they are susceptible to severe damage and catastrophic failure. For two decades Dexmet has been working with aircraft designers developing precision expanded MicroGrid foils for lightning strike protection on carbon fiber composite aircraft and its components. Benefiting from the development work done in the aircraft industry, Wind Blade Manufacturers are now realizing the importance of having the proper lightning strike protection for larger carbon fiber blades. As with Aerospace applications, weight is always critical so Dexmet provides different conductive materials to minimize the weight based on the different strike zones. As with all rotary blades, lighting is more prone to hit the leading edge and the outer blade surfaces towards the tips where the highest amount of static energy is generated. For these locations, the heavier, more conductive materials are utilized. As you move towards the root of the blade, a lighter weight material can be incorporated to reduce weight and cost. The variability with Dexmet’s expanding process provides the capability of producing a custom material based on desired weight, conductivity, or open area to meet exact application requirements.

LEADERSHIP IN WIND ENERGY In 1942 the “North Bar Tool Company” (as Norbar was then known), became the first company in Britain to commercially manufacture a torque wrench. The initial demand was driven by the need for the gasket-less cylinder head of the Rolls Royce Merlin engine to be accurately tightened. Bill Brodey and his partner Ernest Thornitt obtained a license from Britain’s war-time Government to begin manufacture of torque wrenches and Norbar was born. Since then, Norbar has continued to invest in the very latest design, manufacturing and quality control technology to achieve the highest level of innovation and precision in the field of torque control equipment.

Rotor Clip is a global leader in the manufacture of tapered, constant section and spiral retaining rings meeting Inch, DIN, ANSI Metric and JIS standards. This includes the manual and automatic tools needed to install/remove every ring we sell. Rotor Clip also manufactures wave spring rings as well as self-compensating hose clamps, all produced in a lean environment dedicated to eliminating waste and ensuring quality through IATF 16949, ISO 9001 & ISO 14001 registration, and AS9100C certification.
Bearing Retention & Preload Solutions through Engineering Expertise. Rotor Clip TruWaveÂŽ single-turn wave springs are suited for applications that include connectors, fluid power seals, noise and vibration attenuation, and bearing preload.
The design of standard single turn wave springs with gap typically used for preloading components features sharp corners at the cut off area of the spring ends. These sharp corners can scratch the surface of the bearing as well as the mating parts when the wave form shows a steep incline depending on the load specification.
As with all of our wave spring designs, there is no charge for tooling on custom designs with this end feature. Feel free to contact our technical sales staff (tech@ rotorclip.com) to find out if your design can benefit from our new single-turn wave spring design. Maybe you have questions about another of our retaining ring, wave spring or hose clamp products. Our technical sales engineers are here to help you find the right solution for your application. www.rotorclip.com
Rotor Clip’s patented single-turn wave spring design solves this problem by flattening the ends of the spring so that they will not create excessive wear that can damage the application. This new design also offers the potential for cost and weight savings in applications where design engineers would typically choose a multi-turn wave spring with shim ends to prevent wear on mating components. However, multi-turn wave springs with shim ends require more material in their production, which adds to both cost and weight.

EVERYONE NEEDS
PROTECTION...
…Especially from lightning.
The Megger DLRO10HD and DLRO10HDX offer reliable testing to make sure you’re protected in the event of a lightning strike. When a strike occurs, current flows to ground through the lightning protection system. The system’s resistance to ground should be measured regularly to ensure that the protection will work when needed. For these measurements a low resistance ohmmeter, like the DLRO10HD and DLRO10HDX, should be used. Megger also makes a test lead set specifically designed for testing wind turbines. They are long enough to assess the continuity of lightning protection conductors in wind turbine blades and are ideally suited for use with the DLRO10HD.
Features of the wind turbine lightning protection test lead set include: n
Available in 3 different lengths to 328 ft
n
Suitable for use on site or in the manufacturing plant
n
10A rated
