1.05-GW Iowa Wind Expansion Moves Forward

12/16/2013 | Aaron Larson

MidAmerican Energy Co. is already the top ranked, rate-regulated utility owner of wind generation in the U.S. and with 448 new wind turbines being added in Iowa—the largest wind expansion in the state’s history—its hold on that position will be further strengthened.

In November, the company announced it had reached an agreement with Highland Wind Energy LLC for the acquisition of the 500-MW Highland wind project site in O’Brien County. Agreements were also reached with EDF Renewable Energy for the acquisition of the 250-MW Lundgren wind project site in Webster County and with RPM Access LLC for the acquisitions of two projects—the 138.6-MW Wellsburg wind project site in Grundy County and the 117-MW Macksburg wind project site in Madison County. In addition, it was announced that MidAmerican would expand its existing Vienna II wind project in Marshall County, constructed in 2012, by 44.6 MW.

Siemens will supply the wind turbines for all five projects. The turbines will utilize the company’s 2.3-MW G2 platform technology. The purchase is the largest single order for onshore wind power awarded globally to date. All of the blades for the expansion will be manufactured at Siemens’ Fort Madison, Iowa, facility, while the nacelles will be manufactured at Siemens’ Hutchinson, Kan., facility. The contract includes a service, maintenance, and warranty agreement.

“Siemens not only leads the way for offshore wind power worldwide, we are also a very successful player in the onshore wind industry. In Europe and Africa alone, we successfully installed more than 1 GW in the last fiscal year. This new order from MidAmerican Energy once again highlights that we are one of the leading suppliers in the U.S. wind power market,” said Markus Tacke, CEO of the Wind Power Division of Siemens Energy.

Iowa is one of the leading U.S. states in wind energy generation. In 2012, approximately 24% of total generation in the state was provided by wind power. MidAmerican, for its part, already has 1,267 wind turbines in Iowa. When the projects are complete—scheduled by year-end 2015—approximately 39% of MidAmerican Energy’s generation portfolio will come from wind resources associated with its 1,715 wind turbines.

The wind expansion will provide more than $3 million in landowner payments each year and more than $360 million in additional property tax revenues over the next 30 years. The expansion will be constructed at no net cost to the company’s customers and will help stabilize electric rates over the long term. Approximately 1,000 construction jobs will be added to Iowa’s economy during the two-year construction period and approximately 40 new permanent jobs will be added when the expansion is complete.

“We look forward to continuing positive relationships with state and county officials as well as landowners and other local residents during the construction and operation of the new wind farms,” said Bill Fehrman, president and CEO, MidAmerican Energy. “Not only will the projects bring jobs and other economic development to the state, they will enhance MidAmerican Energy’s renewable energy portfolio—making additional affordable, environmentally responsible energy to benefit our customers.”

Wind Production Tax Credit Expires with Uncertain Impact

The controversial federal production tax credit (PTC) bestowed on new wind farms of $0.023/kWh for the first 10 years of their operation expired on Tuesday, but the impact of that policy lapse isn’t immediately clear.

Originally enacted in 1992, the federal renewable electricity PTC has been renewed and expanded numerous times—most recently by the American Recovery and Reinvestment Act of 2009 and the American Taxpayer Relief Act of 2012 in January 2013.

Congressional extension of the tax credit last year made the significant change of removing “placed in service” deadlines and replacing them with deadlines that use the beginning of construction as a basis for determining facility eligibility. Last year, Congress extended the deadline for wind energy facilities by one year, from Dec. 31, 2012, to Dec. 31, 2013.

According to the American Wind Energy Association (AWEA), the estimated impact of uncertainty posed by the PTC’s expiry is still being vetted. The most uncertainty will be felt by wind manufacturers, which could see orders in the pipeline dry up, the industry group noted.

But Rob Gramlich, AWEA’s senior vice president of public policy, told POWERnews on Thursday that while the wind sector already saw a “sharp slow-down” in the first six months of 2013, utilities have been signing a record number of power purchase agreements for wind energy. “The change made to the PTC in 2013 allows projects that start construction this year to qualify for the PTC, which acknowledges the 18-24 month timeline of wind projects, and will allow companies to continue to build projects past 2013,” he noted. “We continue to see evidence that the [PTC] is an effective tool that is working.”

AWEA will continue to push for more certainty in the medium and long term, Gramlich said. “The legislative vehicle could be tax reform, an extenders package, or something else, but ultimately our industry will begin to feel the impacts of uncertainty in 2014.”

The group, in December, lauded a proposal put forth by Senate Finance Committee Chair Max Baucus (D-Mont.) to streamline energy tax incentives so they are more predictable and technology-neutral.

The discussion draft notes that under current law there are 42 different energy tax incentives, including more than a dozen preferences for fossil fuels, ten different incentives for renewable fuels and alternative vehicles, and six different credits for clean electricity. Of the 42 different energy incentives, 25 are temporary and expire every year or two, and the credits for clean electricity alone have been adjusted 14 times since 1978—an average of every two and a half years. “If Congress continues to extend current incentives, they will cost nearly $150 billion over 10 years,” Sen. Baucus said in a statement on Dec. 18.

Feedback on the discussion draft is requested by Jan. 31, 2014. However, some industry observers caution that the measure could stall in Congress even though it has broad bipartisan support.

Meanwhile, some renewable power groups have opposed the proposed reform. For the Solar Energy Industries Association, the nation’s largest solar power lobbying group, “reducing the solar Investment Tax Credit (ITC) and dramatically altering the way companies depreciate their assets could jeopardize future clean energy development in the United States.”

La Ventosa Wind Farm Capacity Increased By 27.5%

Eleven new wind turbines have been added at the La Ventosa wind power complex in Juchitán de Zaragoza, Oaxaca, Mexico, raising the total capacity to 102 MW.

Iberdrola, owner of the wind farm, has utilized Gamesa technology exclusively at all of its installations in Mexico. In this instance, 2-MW G80 wind turbines, standing 78-meters (256-feet) tall, were installed. The project also upgraded the wind farm’s grid connection and the 230-kV transmission line.

In addition to the La Ventosa site, Iberdrola also operates the 102-MW La Venta III complex and the 26-MW Bii Nee Stipa wind farm for a total renewable capacity of 230 MW. Mexico accounts for more than 11.5% of the company’s 44.9-GW installed generation capacity, all of which—other than the wind farms—is from gas-fired combined cycle power plants.

Federal Court Upholds FAA “No Hazard” Determination for Cape Wind

A federal court on Wednesday upheld the Federal Aviation Administration’s (FAA’s) 2012 determination that the 130-turbine Cape Wind offshore wind farm proposed for Nantucket Sound, south of Cape Cod, Mass., posed “no hazard” to air navigation.

The U.S. Court of Appeals for the District of Columbia Circuit’s decision in Town of Barnstable, Mass. v. FAA marks a major development in one of many long-standing legal disputes that has delayed the controversial project by more than 13 years. This suit involves the Department of Interior (DOI), the FAA, citizen groups, and developers of the nation’s first commercial offshore wind farm.

The FAA issued its third “No Hazard Determination” in 2010, shortly after the DOI issued its approval for Cape Wind. But the D.C. Circuit in October 2011 remanded the decision to the FAA, finding that the federal agency erroneously focused just on whether the turbines met the technical definition of obstruction (whether they exceeded 500 feet) without considering separately whether they would interfere with air navigation. The decision handed a legal victory to opposition groups, including the Alliance to Protect Nantucket Sound and the Town of Barnstable.

In July 2012, meanwhile, Republican lawmakers initiated a Congressional investigation to probe whether the FAA disregarded safety concerns and approved the Cape Wind project for political reasons.

But the FAA ultimately issued a public notice of its reinstated project review in February 2012 indicating that “[n]one of the turbines would have an adverse effect on the use of air navigation facilities or navigable airspace,” following that action in August 2012 with its fourth No Hazard Determination. The Alliance to Protect Nantucket Sound challenged that determination, but in a decision on Wednesday, the D.C. Circuit denied its review.

The project has secured all required permits and has been issued a commercial lease and received approval for its construction and operations plan by the DOI. In December, developers signed a major contract with Siemens for the supply of 3.6-MW offshore wind turbines, an offshore electric service platform, and a service agreement for the first 15 years of commercial operations. Cape Wind developers say they have sold 77.5% of the project’s power output in long-term power purchase agreements to National Grid and NSTAR, but it is still in the financing phase.

“The Alliance to Protect Nantucket Sound, the Town of Barnstable and their financial backer—coal billionaire Bill Koch—have failed yet again in their continuing campaign to use the courts to delay the financing of Cape Wind,” Cape Wind Communications Director Mark Rodgers said on Wednesday. The decision is of even more importance because “this was the same court that had previously provided project opponents their sole and temporary relief, opponents have lost all 12 legal decisions in other courts.”

In a statement, the Alliance to Protect Nantucket Sound contested that the federal court’s ruling was “a green light for Cape Wind.” At least four other federal lawsuits are pending in U.S. District Court in D.C., and the group had filed a new lawsuit challenging the project’s “high-priced” contract with NSTAR, it noted. That suit alleges that Massachusetts regulators discriminated against out-of-state power companies despite their lower costs by pressuring NSTAR to buy power from Cape Wind, in-state energy company.

“Cape Wind is an outdated project that would cost ratepayers three times the price of other readily available renewable energy adding billions of dollars in unnecessary electricity fees. While we are disappointed with today’s court decision, it will make no difference in the long run. It becomes clearer every day that Cape Wind should not and will not be built,” the group said.

GE launches advanced technology space frame tower for Wind Turbines in Spain

GE’s renewable energy business announced that the introduction of its new space frame tower for multi megawatt wind turbines at the European Wind Energy Association’s annual conference in Barcelona, Spain.

The 5 legged enclosed lattice tower from GE enables towers up to 139 meters to be built more cost-effectively in never before accessible locations, using a logistics friendly model of standard shipping methods and on site assembly.

Mr Cliff Harris, GM of GE’s renewable energy business in Europe, said that “The space frame tower helps our customers go taller in new locations, further enabling the growth of wind energy. This next innovation in wind turbine technology is a stepping stone towards towers taller than 150 meters in Europe. GE will continue to drive innovation and advanced technology for the wind industry in the coming years.”

The space frame tower is being introduced with GE’s new 2.75-120 wind turbine and was demonstrated in a full-scale turbine at GE’s prototype site in Tehachapi, California. The lattice tower is assembled at wind farm locations and then wrapped in an architectural fabric to provide familiar solid structural aesthetics. The tower improves serviceability with increased space down-tower, maintenance free bolting system and custom methods and fixtures for efficient installation and dismantling.

The space frame tower features a wide base supported by five legs that provide more room at the base of the tower than a traditional tubular tower. The additional down tower space allows for storage within the turbine for ease in maintenance, site organization and balance of plant. Parts manufacturing can be automated with the space frame tower to optimize quality control of the structure. The fabric casing is durable, weather resistant and does not need to be replaced during turbine life.

The space frame tower is a product of GE’s technology evolution and investment. GE has invested more than USD 2 billion into renewable energy research and development to continually provide customers with the most advanced wind technology available and position wind as a mainstream energy source.

Suzlon Announces Sale of 240 MW Big Sky Wind Farm to EverPower Wind Holdings Inc

Suzlon Group has announced the strategic sale of the 240 MW Big Sky Wind Farm in Illinois to EverPower Wind Holdings, Inc. Suzlon Group had recently acquired the Big Sky wind farm from Edison Mission Energy via their fully owned US-based subsidiary Suzlon Wind Energy Corporation.

Suzlon Group has signed a definitive agreement with EverPower to sell the project located in Illinois, about 95 miles west of Chicago.

This acquisition of Big Sky by EverPower makes it the nation's 18th largest wind generator, with a combined capacity of 752 MW in the US in winder power generation.

Mr Duncan Koerbel, CEO of Suzlon Wind Energy Corporation and CTO of the Suzlon Group, said that "We are very pleased to welcome EverPower to the Suzlon family of customers. The SWECO OMS team looks forward to partnering with EverPower to maintain the high standards of availability and reliability at Big Sky that we have seen since operations started at Big Sky 4 years ago."

Mr James Spencer, President and CEO of EverPower, said that "We are pleased to add this project to our portfolio. It fits into both our overall growth strategy and our strategy of building our portfolio in liquid markets like PJM."

Mr Kirti Vagadia, Group Head of Finance at Suzlon, said that "This sale of Big Sky Wind Farm to a sound long term investor like EverPower is an important part of our dis-investment strategy to hive off non-core assets, and the net proceeds of the sale will be used to fuel our business growth." Completed in early 2011, the Big Sky Project utilizes 114 Suzlon 2.1 MW S88 turbines to generate enough electricity per annum for nearly 50,000 homes while also offsetting over 225,000 tonne of CO2 emissions.

Canada’s Largest Wind Project Completed

The 270-MW South Kent Wind project has been completed in Ontario. The project includes 124 wind turbines and is the largest wind power facility in Canada.

The wind farm utilizes Siemens 2.3-MW wind turbines with blades manufactured at the company’s Tillsonburg facility and towers made by CS Wind at its Windsor location using Ontario-made steel. The project includes a unique night-lighting system. The feature—called TowerSHADE—eliminates light visibility from below the turbine out to almost a mile, but allows aircraft to see the light from above.

Pattern Energy Group Inc. and Samsung Renewable Energy Inc. teamed up to build the project, which employed about 500 workers during construction. Pattern Energy expects the local Chatham-Kent economy to continue benefiting from direct spending of more than $7 million per year attributed to the development.

Samsung and Pattern Energy are also constructing the 150-MW Grand Renewable Energy Park in Haldimand County, Ontario, and are working on two other projects—Armow Wind in the Municipality of Kincardine and K2 Wind in the township of Ashfield-Colborne-Wawanosh. The total capacity of the four renewable energy projects would be 870 MW, if all were to be completed as planned.

“South Kent Wind is our first in a series of wind projects in Ontario and we’re proud it has been delivered on time and within budget, despite a very harsh winter,” said Mike Garland, CEO of Pattern Energy.

DOE Picks Three Offshore Demonstration Projects to Proceed to Phase II

The Department of Energy (DOE) on Wednesday selected three projects to proceed to the second phase of its offshore wind advanced technology demonstration initiative: Fishermen’s Atlantic City Windfarm, Principle Power’s Oregon project, and Dominion Virginia Power’s Virginia Beach project.

Assistant Secretary of the DOE’s Office of Energy Efficiency and Renewable Energy (EERE) David Danielson revealed the three projects—of seven initially chosen for the first phase of the demonstration program—had been selected to proceed to Phase II at WINDPOWER 2014 in Las Vegas, Nev.

Principle Power plans to install five semi-submersible floating foundations (WindFloat) outfitted with Siemens 6-MW direct-drive turbines in deep water 15 miles from Coos Bay, Ore. Fishermen’s Energy plans to install five 5-MW XEMC direct-drive turbines in state waters three miles off the coast of Atlantic City, N.J., while Dominion Virginia Power plans to install two Alstom 6-MW direct drive turbines off the coast of Virginia Beach.

Both Dominion and Fishermen’s projects will use innovative “twisted jacket” foundations that are as strong as traditional jacket structures but use substantially less steel. “If the projects successfully demonstrate the twisted jacket foundations, engineers may use the design in future offshore wind projects in locations such as the Atlantic Wind Energy Areas established by the Bureau of Ocean Energy Management,” said the DOE in a statement on Wednesday.

Each selected project may receive up to $47.7 million in cost-shared funding, the DOE said, including $7.7 million to complete front-end engineering design.

Commerce Backs Distributed Wind Growth

The U.S. Department of Commerce on May 13 awarded the Distribution Wind Energy Association (DWEA) a two-year grant to develop a roadmap to identify common manufacturing gaps for distributed wind equipment.

The $488,634 grant from the National Institute of Science and Technology (NIST) calls on DWEA to form the “Strategies for Manufacturers Advancing Research and Technology [SMART]” consortium, which will comprise distributed wind energy equipment manufacturers, suppliers, customers, and university researchers. The consortium will be tasked with developing strategies to further distributed wind industry growth and advance innovative manufacturing techniques.

The global distributed wind energy systems market is forecast to grow to $2 trillion by 2030, and U.S. manufacturers of these systems—assemblies of power electronics, composite blades and towers, shafts, bearings, and an array of other electrical, mechanical, and structural components—are world leaders in what is still a small global market.

However, “foreign manufacturers have entered the market, many with systems that mimic the design of U.S. technology. To maintain their edge in a growing global market, U.S. manufacturers must accelerate research and development efforts aimed at improving production processes and driving down component costs,” said NIST.

NRG to Acquire North America’s Largest Wind Farm

NRG Energy’s shopping spree, which has seen it become the nation’s largest merchant generator through a string of acquisitions, continued this week as subsidiary NRG Yield announced on June 4 that it has agreed to acquire the mammoth Alta Wind facility in Tehachapi, Calif., from Terra-Gen Power LLC.

The Alta Wind farm has an operating capacity of 947 MW and is the largest wind facility in North America. The deal will cost NRG Yield $870 million plus the assumption of $1.6 billion of non-recourse project financings, subject to customary working capital adjustments.

The wind farm is located in a well-established wind resource area and is close to the Los Angeles load center. There are 386 turbines that have been placed into commercial operation within the past four years. The power is contracted under long-term power purchase agreements with Southern California Edison.

“Alta Wind is a landmark investment for NRG Yield,” said David Crane, chairman and CEO of NRG Energy. “Alta Wind contributes to our objective of sustainable and visible dividend growth for our investors while supporting the generation of carbon-free electricity for thousands of homes through large-scale wind.”

The deal follows NRG’s acquisition of Edison Mission Energy (EME) in March, when it purchased 42 plants and 8.9 GW of capacity for $2.6 billion through EME’s bankruptcy reorganization plan, and its 2012 merger with GenOn.

NRG Yield owns contracted renewable and conventional generation, and thermal infrastructure assets in the U.S.—including fossil fuel, solar, and wind power generation facilities. Its thermal infrastructure assets provide steam, hot water and/or chilled water—and in some instances electricity—to commercial businesses, universities, hospitals, and governmental units.

The company expects to close the deal in the third quarter of 2014. The transaction is subject to customary closing conditions, including the receipt of regulatory approval by the Federal Energy Regulatory Commission, the U.S. Department of Justice, and the Federal Trade Commission under the Hart-Scott-Rodino Act, as well as notice of the acquisition to the California Public Utilities Commission.

Buffett wil 15 miljard dollar in duurzame energie verdubbelen

DINSDAG 10 JUNI 2014, 13:58 uur | 631 keer gelezen

Momenteel investeert Berkshire Hathaway, het bedrijf van miljardair Warren Buffett, zo’n 15 miljard dollar in wind- en zonne-energie in de Verenigde Staten. Als het aan Buffett zou liggen, zou hij dat bedrag verdubbelen.

Dat zei de superinvesteerder maandag op de jaarlijkse bijeenkomst van Edison Electric Institute in Las Vegas, zo schrijft persbureau Bloomberg.

Berkshire Hathaway, in marktwaarde het op vier na grootste bedrijf ter wereld, investeert aanzienlijke bedragen in kapitaalintensieve- en energiebedrijven. Een bijvoorbeeld is BNSF Railway, een Amerikaanse spoorwegmaatschappij.

Focus meer naar duurzaamheid

‘Buffett kijkt met Bershire Hathaway altijd naar de toekomst’, zegt Lawrence Cunningham, hoogleraar aan de George Washington University en auteur van ‘Berkshire Beyond Buffett’. ‘Dat betekent dat het bedrijf nog meer de focus zal leggen op duurzaamheid.’

Volgens Buffett leveren nutsbedrijven niet de rendementen die hij graag zou zien, maar voorzien ze wel in de mogelijkheid om te herinvesteren en overnames te doen. In 2000 kocht hij een energie holding uit Iowa en breidde het uit naar wat nu Berkshire Hathaway Energy heet. Dat bedrijf exploiteert nu elektriciteitsnetwerken in Groot-Brittannië en aardgasleidingen in de Verenigde Staten. Het bedrijf investeert in duurzame energie via windmolenparken in Iowa en Wyoming, en via zonne-energiebedrijven in Californië en Arizona.

Herinvesteren

In tegenstelling tot veel andere nutsbedrijven herinvesteert Berkshire Hathaway Energie alle winsten. Buffett gaf op de bijeenkomst aan dat dit beleid voortgezet zal worden, en dat dit inhoudt dat de komende 10 jaar ongeveer 30 miljard dollar geherinvesteerd zal worden. ‘We blijven dit tot in lengte van dagen doen. We gaan gewoon door.'

Investeringen in duurzame energie zijn hard nodig in de Verenigde Staten om minder afhankelijk te worden van fossiele brandstoffen. ‘Het is zeer bemoedigend dat Buffett in duurzame energie wil investeren’, zegt Nick Akins, CEO van American Electric Power. ‘Onze industrie heeft een sterke behoefte aan kapitaal.’

DOE Takes Steps to Offer Cape Wind $150M Loan Guarantee

The much-delayed Cape Wind offshore wind project could be the latest recipient of a federal loan guarantee from the Department of Energy (DOE).

The agency on Tuesday announced the first step toward issuing a $150 million loan guarantee with a conditional commitment to Cape Wind Associates. The guarantee will support construction of the 360-MW offshore wind facility that is under development off the coast of Cape Cod, Mass.

The DOE is now expected to continue monitoring the project’s development and work to reach final agreement before closing the loan guarantee. “Under the proposed financing structure for the Cape Wind project, the Department would be part of a group of public and private lenders. This co-lending arrangement will help build private sector experience with offshore wind projects in the U.S. while reducing taxpayer exposure,” the DOE said in a statement on Tuesday.

The project has secured all required permits and has been issued a commercial lease and received approval for its construction and operations plan by the Department of Interior (DOI). In December, developers signed a major contract with Siemens for the supply of 3.6-MW offshore wind turbines, an offshore electric service platform, and a service agreement for the first 15 years of commercial operations. Cape Wind developers say they have sold 77.5% of the project’s power output in long-term power purchase agreements to National Grid and NSTAR, but it is still in the financing phase.

However, the controversial project has been plagued by many long-standing legal disputes that have delayed it by more than 13 years. Legal claims raised include arguments over navigational safety, alternative locations, alternative technologies, historic preservation, Native American artifacts, sea turtles, and the adequacy of the project’s environmental impact statement and biological opinions. This March, a U.S. District judge upheld the DOI’s review and approval of the project, and rejected a set of four major lawsuits against the project.

Cape Wind says project opponents are “largely funded by coal and petroleum coke magnate William Koch.”

Financing is slated to be completed during the second half of 2014, and construction will “commence shortly following the completion of financing,” developers of the project say.

Massive Wind-CAES Project Proposed to Power Southern California

A coalition of four companies are proposing to build a 2.1-GW, $8 billion project that would comprise the world’s largest wind farm in Wyoming, a huge compressed-air energy storage (CAES) system in Utah, and a 525-mile transmission line that would supply up to 9.2 TWh per year of electricity to Southern California.

Pathfinder Renewable Wind Energy, Magnum Energy, Dresser-Rand, and Duke-American Transmission announced the proposal at a media conference on Sept. 23.

The $4-billion wind farm, to be built, owned, and operated by Pathfinder, would cover 150,000 acres in Chugwater, Wyo., about 40 miles north of Cheyenne, using turbines supplied by General Electric. The area planned for the site has been identified as having some of the highest wind potential in the country.

The $1.5-billion, 1.2-GW, CAES facility would be developed by Pathfinder, Magnum, and Dresser-Rand at a site near Delta, Utah, 130 miles southwest of Salt Lake City, and would employ four 41-million-cubic-foot caverns to be carved out of an underground salt formation. Excess generation from the wind farm would be stored as high-pressure air during the periods of low demand, and the air would be used to drive a natural gas–fired combined cycle plant when demand is high.

Dresser-Rand previously developed the only CAES plant in the U.S., the 110-MW Power South project in McIntosh, Ala. Though the new plant would run on natural gas, the use of compressed air from the salt caverns will greatly increase the plant’s efficiency and responsiveness. Projected efficiency for the new plant is hoped to be around 85%, according to Dresser-Rand literature. Dresser-Rand is also developing a 317-MW CAES project in Texas.

The $2.6 billion transmission line, to be built by Duke, would connect the wind farm to the CAES facility, traversing Wyoming, Colorado, and Utah. Power from the CAES plant would be carried to the Los Angeles area by an existing 490-mile high-voltage line.

A formal proposal will be delivered to the Southern California Public Power Authority in 2015, the companies said. Jeff Meyer, managing partner of Pathfinder, likened the proposal to a “21st century Hoover Dam.”

A 2013 study by the National Renewable Energy Laboratory (NREL) identified the Wyoming-wind-to-California corridor as one of the most promising renewable energy markets in the nation. NREL projections found that power from such a project would be competitive with gas-fired generation in California even without incentives for renewable energy.

U.S. Can Reach 50% Renewable Generation by 2030, Says IRENA

01/12/2015 | Thomas Overton

The U.S. could get nearly 50% of its generation from renewable sources by 2030 with existing technologies and the right policies and investments, according to a report released by the International Renewable Energy Agency (IRENA) on Jan. 12.

The report is one of the first in IRENA’s Remap 2030 series, which explores how to double the global share of renewable energy from 18% to 36% by 2030. A previous report released in November 2014 analyzed prospects for renewable energy in China. Reaching the 50% threshold for power generation would raise the renewable share of the overall U.S. energy mix from 7.5% in 2010 to 27% by 2030.

The U.S., the report says, “has the potential to become a centre of renewable energy thought and innovation, and to become the world’s second largest user of renewables after China;” however, “[w]ithout a widespread and systematic policy shift, the U.S. risks falling far short of this potential.”

Reaching this goal, says the report, would require average investments of $86 billion a year, though this would represent only a $38 billion increase over what would be spent during this period under a “business as usual” scenario. The report claims that making the shift would result in $30 billion to $140 billion in savings for the U.S. economy from reduced health effects and CO2 emissions.

The largest share of new generation would come in wind. The report envisions a fivefold increase in onshore wind capacity—most of it installed in the central U.S. plains—from 63 GW in 2014 to 314 GW by 2030. Another 40 GW of offshore wind capacity would also be needed. Solar—photovoltaic (PV) and concentrating solar power—would also rise dramatically, from around 16 GW currently to 135 GW in 2030. About one-third of PV capacity would be distributed.

Biomass and bioenergy capacity would nearly double to 84 GW, with about 40% of this being industrial cogeneration. The remaining increase would come in geothermal, with additional input from small-scale hydropower.

The report projects that the new renewable capacity will largely replace coal and nuclear as its levelized cost of energy will fall below those options. Gas will remain competitive because of abundant supplies keeping fuel costs down.

While annual subsidies of around $46 billion will be necessary by 2030, most of this will be needed in end-use sectors such as electric vehicles and building heating and efficiency improvements rather than in the power sector, where the report projects that subsidies such as the Production Tax Credit can be phased out. Most renewable generation will be cost-competitive without subsidies by 2030, IRENA predicts.

However, getting to this level of renewables will require “dramatic” investment in transmission and distribution because of the long distances between population centers and many of the nation’s best renewable energy resources, in addition to expanded energy storage capacity and smart grid capabilities.

Besides the new costs, “developing technology to harvest the plentiful renewable resources, operating procedures to integrate them on the grid, and regulatory structures to ensure that the grid is reliable and that value and costs are shared appropriately among stakeholders are main implementation challenges.”

Developing a better planning process for new transmission infrastructure will be necessary, as will policy changes to remove regulatory barriers to interconnection, which are significant in some areas, particularly the southern U.S.

The report does not recommend a carbon-pricing or cap-and-trade regime, though it does suggest that the U.S. “[b]etter account for the external costs related to human health and [greenhouse gas] emissions in fossil fuel pricing.” It also envisions national targets for renewable energy, both in generation and end-use, as well as continued support for research and development.

The study did not consider grid integration and system-related costs, though other studies it reviewed suggest these do not become challenging until renewable penetration in the overall energy mix exceeds 30%.

Though the report did not consider climate change in detail, it does predict that implementing the recommendations would result in a 30% cut in U.S. CO2 emissions by 2030, which are in line with new pledges to reduce emissions 26% to 28% by 2025.

Suzlon Group commissions 350MW wind energy projects in Brazil

PTI reported that Suzlon Group, wind turbine maker, today said it has commissioned wind energy projects having a total capacity of 350 MW in Brazil.

The company said in a statement that “Suzlon Group has announced installing and commissioning of over 350 MW wind energy in Brazil over a period of 16 months ending November 2014.”

These projects are located in the high wind states of Rio Grande do Norte and Ceara in Brazil.

The installations include 150 wind turbine generators.

Mr Tulsi R Tanti, Chairman of Suzlon Group, said that “We remain focused on high growth and emerging markets and Brazil is a key geography of our growth strategy. Suzlon is committed to contribute to Brazil’s energy basket by reducing its carbon footprint and bridging the country’s power needs.”

These projects will contribute to reducing Brazil’s carbon footprint by eliminating approximately 0.54 million tonne of carbon dioxide emissions per annum.

The 350 MW projects completed are expected to light up 1 lakh households in Brazil with clean energy.

Suzlon entered the Brazilian market in 2008 and has since created a cumulative installed capacity of approximately 750 MW.

One Step Back, One Step Forward for U.S. Offshore Wind

Though offshore wind is becoming increasingly important in Europe, with many hundreds-of-megawatts projects in service, the sector has stagnated in the U.S., with no operational facilities—and some high-profile failures.

In early January, the 468-MW Cape Wind project in Massachusetts, which was on track to become the nation’s first offshore wind farm, abruptly lost its power purchase agreements (PPAs) after the developers missed a deadline to close financing and begin construction. The project faced extended litigation from opponents, which observers believe may ultimately have killed it (see “Cape Wind Finally Blows Out” in the March 2015 issue).

That event left another, albeit much smaller, project the frontrunner for the first offshore facility to come online in the U.S. About two weeks after Cape Wind suffered its setback, Deepwater Wind, the developers of the five-turbine, 30-MW Block Island Wind Farm off Rhode Island, announced that improvements in turbine technology would allow it to generate more power than originally envisioned under its PPA with National Grid (Figure 2).

The project was expected to have a capacity factor of 40% when the PPA was approved. Deepwater Wind said it now expects the farm to operate at a 47% capacity factor because of improvements in the turbine technology. Because, under the terms of the PPA, any power it generates over the PPA has to be sold at half price, this may mean a reduction in the overall price of its power.

Deepwater Wind closed financing on the $255 million project on Mar. 2 and has begun preliminary construction and fabrication. The company plans to begin installing the turbine foundations this summer, with commercial operation slated for late 2016.

Meanwhile, the failure of Cape Wind has led two Massachusetts lawmakers to propose changes in the state’s renewable energy legislation. If passed, the bill would require the state’s utilities to sign PPAs for 1,500 MW of offshore wind capacity by 2018.

Long-term prospects for offshore wind in the U.S. remain uncertain. A federal auction for offshore wind leases in January drew lackluster participation, with two leases going unsold and two more selling for barely more than the minimum bids.

New York to invest USD 160 mln in renewable energy projects

Wind Power Monthly reported that the New York state government has pledged USD 160 million to help renewable energy projects.

Mr Andrew Cuomo, Governor of NY, said that the investment would be handed out through a competitive process.

A deadline of May 8th has been set for project owners to notify the New York State Energy Research and Development Authority of their intention to bid.

NYSERDA will announce the winners of the bidding process in July 2015, with successful applicants being offered a contract of up to 20 years by the state.

The funding is part of the state government's 'Reforming the Energy Vision' initiative that supports the growth of renewable energy.

According to Windpower Intelligence, the data division of Windpower Monthly, New York state has just over 1.7 GW of wind capacity installed.

Three new projects gives another boost to wind power in B.C

The Vancouver Sun reported that BC Hydro has signed agreements to buy electricity from 3 small wind projects, including the first 2 wind farms in the Okanagan.

The projects will add 45 MW of wind power and bring BC Hydro’s total wind power capacity to 700 MW, about 4% of Hydro’s power generation. The new projects will provide enough electricity to power 14,000 homes.

Hydro expects construction on the 3 projects, owned by White Rock-based Zero Emission Energy Developments Inc, to begin in late spring or early summer. Construction is expected to take 18 months.

Wind is one of the forms of clean energy, which also includes run-of-the-river hydroelectricity, that the provincial utility has purchased to supplement its large hydro dams.

Both wind and run-of-the-river power is criticized because the projects produce electricity only intermittently.

Mr Doug Little, BC Hydro’s vice-president of energy planning, said that on wind farms produce electricity about 35% of the time.

Hes aid that “But it is a very good fit with our hydroelectric system because we’ve got these big reservoirs. So when the wind is blowing, and all these wind farms are generating electricity, we can turn down our large-hydro generation a little bit and save the water for use when the wind is not blowing.”

Mr Little said that the cost of the power, about USD 100 a megawatt-hour, was also competitive with other forms of new clean energy such as run-of-the-river.

Hydro has a mandate under the Clean Energy Act to make sure whatever power sources it adds keep the province’s electricity supply at 93% renewable energy.

Little is confident the 3 new projects will be built, as they had to have permits in place before the 40 year power purchase agreements could be signed.

Each 15 MW project will have five turbines, 100 metres high with blades just under 50 metres long. The area that each project will encompass varies from 300 hectares to 700 hectares.

That’s much smaller than most wind farms. The 142 MW Quality Wind project near Tumbler Ridge has 79 turbines, and others in the world have hundreds.

The Pennask wind farm will be about 44 kilometres west of Kelowna, and the Shinisk wind farm 33 kilometres southwest of Summerland. The third project is near Taylor in northeast B.C, a region that is already home to 3 much larger wind farms.

Mr Alastair King, president of Zero Emission Energy Developments, said that his company has financing lined up and is ready to begin construction this spring.

Zero Emission’s majority owner is Anemos Energy, based in Hamilton, Ontario.

Mr King said that “The company was started by myself in 2007 and this is what we’ve been working toward. We are very excited. I think we will be even more excited when the turbines are turning and we are generating power.”

He would not disclose a price tag for the 3 B.C. projects but said it was significant.

The 102 MW Bear Mountain Wind project near Dawson Creek, with more than twice the generation capacity, cost about USD 200 million.

The 15 MW projects did not require a full-scale review by the B.C. Environmental Assessment Office, but were scrutinized by the Ministry of Forests as part of a Lands Act review.

Mr King said that the projects will be built to mitigate effects on the environment, including those on birds and bats.

The public had raised concerns about such issues at company sessions to discuss the project.

Mr Peter Waterman, Summerland Mayor, said that his community has been supportive of efforts for cleaner and greener approaches to development. This certainly fits that bill.

Other wind projects already operating in B.C include the 144 MW Dokie Wind Energy project near Chetwynd and the 99 MW Cape Scott Wind Farm on the northern tip of Vancouver Island.

The 185 MW Meikle Wind project near Tumbler Ridge is under construction and is slated to start producing power in late 2016.

Another project, the 100 MW Isle Pierre Wind Project near Prince George, just entered the environmental review process.
