A wind farm has been paid £1.2 million not to produce electricity for eight-and-a-half hours.

The amount is ten times greater than the wind farm’s owners would have received had they actually generated any electricity.
The disclosure exposes the bizarre workings of Britain’s electricity supply, prompting calls last night for an official investigation into the payments system.
The £1.2 million will go to a Norwegian company which owns 60 turbines in the Scottish Borders.
The National Grid asked the company, Fred Olsen Renewables, to shut down its Crystal Rig II wind farm last Saturday for a little over eight hours amid fears the electricity network would become overloaded.
The problem was caused by high winds buffeting the country in the wake of Hurricane Katia.
In total, 11 wind farms were closed down last week, receiving a total of £2.6 million. The money – detailed in calculations provided by National Grid – will be added on to household bills and paid for by consumers.
As Britain pushes for more and more wind farms, critics claim the size of the ‘constraint payments’ will grow accordingly – raising serious concern about the long-term suitability of wind power to meet Britain’s energy needs.
Crystal Rig received by far the largest single payment because the National Grid runs an auction, inviting energy companies to say how much they want in compensation for switching off.
Crystal Rig’s owners asked for £999 per megawatt hour of energy they would have produced had they been switched on. Incredibly, the figure Crystal Rig had bid was accepted by the National Grid. Continue reading
Six birds found dead recently in Southern California’s Tehachapi Mountains were majestic golden eagles. But some bird watchers say that in an area where dozens of wind turbines slice the air they were also sitting ducks.
The U.S. Fish and Wildlife Service is investigating to determine what killed the big raptors, and declined to divulge the conditions of the remains. But the likely cause of death is no mystery to wildlife biologists who say they were probably clipped by the blades of some of the 80 wind turbines at the three-year-old Pine Tree Wind Farm Project, operated by the Los Angeles Department of Water and Power.
As the Obama administration pushes to develop enough wind power to provide 20 percent of America’s energy by 2030, some bird advocates worry that the grim discovery of the eagles this month will be a far more common occurrence.
Windmills kill nearly half a million birds a year, according to a Fish and Wildlife estimate. The American Bird Conservancy projected that the number could more than double in 20 years if the administration realizes its goal for wind power. Continue reading
Hawaiian Electric Co. has selected Pacific Biodiesel Inc. to supply locally produced biodiesel for an emergency power generation system at Honolulu International Airport.
Maui-based Pacific Biodiesel will provide HECO with at least 250,000 gallons of made from locally recycled cooking oil under the three-year contract, the companies said. The biodiesel will be burned in an 8-megawatt generating station scheduled to be completed in October 2010.
The four generating units at the facility will feed electricity into the HECO grid during normal operations, but will be isolated to power the airport exclusively during an emergency, HECO said.
The Public Utilities Commission has allowed Maui County and the organization Life of the Land to become intervenors in Hawaiian Electric Co.’s proposal to charge customers for a $4 million study on “Big Wind.”
Henry Curtis of Life of the Land said customers should not be forced to finance the studies, because past rulings by the PUC clearly ordered HECO to evaluate alternatives to the massive wind-power project. The commission’s decision and order, which was signed Wednesday, said HECO’s review of the project should have also evaluated alternatives such as expanding residential or large-scale photovoltaic systems, biomass, biofuel and concentrated solar energy.
But although they granted the interventions, the commission also cautioned Life of the Land and the county that their involvement would be limited to the issues currently on the table.
“The commission will preclude any effort by them to unreasonably broaden the issues,” the decision stated.
It then inserted a curious and unusual note that the commissioners said they expect the intervenors “will comply with the commission’s rules and orders.”
County Energy Coordinator Doug McLeod said the language was “interesting,” but he believes there will be some latitude “in what we can legitimately discuss.”
The county’s principal concern from the start, he said, has been “the lack of community benefits from Big Wind.” Continue reading
The development of new renewable energy technologies and other expanding sources of energy such as shale gas will be limited by the availability of water in some regions of the world, according to research by a US thinktank.
The study shows the reliance on large amounts of water to create biofuels and run solar thermal energy and hydraulic fracturing – a technique for extracting gas from unconventional geological formations underground – means droughts could hamper their deployment.
“Water consumption is going up dramatically. We are introducing all kinds of technology to reduce the carbon impact of energy, without doing anything to reduce its impact on water,” Michele Wucker, co-author of the report, told a seminar at the New America Foundation, a thinktank in Washington.
The study, estimating the water consumption of conventional and renewable energy, found even so-called clean energy solutions use vast amounts of water.
Hydroelectricity far outstrips other forms of energy in its use of water, requiring 4,500 gallons to produce a single megawatt hour of electricity – or about the amount needed to run a flat-screen TV for a year. Geothermal energy uses 1,400 gallons per MW/h.
Corn-based ethanol uses a lot of water to irrigate crops, as do nuclear plants which rely on water for cooling systems. Even some renewable energy sources – such as solar farms – are water hogs because they rely on water for cooling. Continue reading
The June 14 article about Maui County’s powerful letter to the Public Utilities Commission – and the county’s decision to intervene in Hawaiian Electric Co.’s request to be reimbursed by ratepayers to the tune of $4 million – contained a number of inaccuracies.
The article identifies two organizations that were denied intervention by the PUC: Life of the Land and Lanaians for Sensible Growth. That is incorrect. The two parties denied intervener status were Friends of Lana’i and Life of the Land.
The article states that the Big Wind project will likely have an enormous impact on Lanai and possibly Molokai. True enough, but one look at the state’s project maps (www.hirep-wind.com/documents/EISPN_PROJECT_AREA_22NOV2010.pdf) confirms for all Maui residents that the state plans to run a cable to/from Maui as well. And First Wind Hawaii, the developer that was unsuccessful in its attempt to develop a wind power plant on Molokai, stated in an April 26 Pacific Business News article that it has now turned its sights to Maui, suggesting that “Maui be included in the interisland cable project.”
The June 14 article’s comments about the deal struck between Castle & Cooke and Pattern Energy also requires clarification Continue reading
Wind energy is cited among the green alternatives to fossil fuel, but environmental and community groups are irritated about the handling of a massive project to transmit energy to Oahu from windmills on Lanai and Molokai. They should be provided more access to preliminary work on the plan by state agencies and Hawaiian Electric Co., and hold project members to promises of full access and participation at future venues.
HECO is seeking a “power purchase agreement” from the Public Utilities Commission to recover $4 million from ratepayers in costs for studies associated with the Big Wind, or Interisland Wind, project. The PUC has endorsed the Hawaii Clean Energy Initiative, which mandates that 40 percent of the state’s energy come from renewable sources by 2030, so the studies are consistent with the state’s goals. The path to getting there, though, has the potential to keep lay people in the dark until it emerges as a fait accompli.
Even Maui Mayor Alan Arakawa is complaining that “no one can tell us where the cable will run, its overall cost or how it would interconnect with the grids on the islands of Maui, Molokai and Lanai.… We need a clear, complete, accurate, detailed analysis for the cable system before we agree to finance it on the backs of the ratepayers.” Continue reading
Maui Electric Co. and other Hawaii utilities once again were ranked among the top utilities in the country for solar power capacity.
MECO parent Hawaiian Electric Co. again was named one of the nation’s Top 10 electric utilities for the amount of solar power added to its system per customer in the the 2010 Solar Electric Power Association Utility Solar Rankings. MECO was ranked in fifth place for total solar watts per customer.
The amount of grid-connected solar is growing fast, and even a little faster than vendors had promised, if the experience of businessmen Thomas Kafsack and Josh Stone is any indication.
Both installed solar generators since the last round of SEPA solar rankings.
Kafsack, operator of Surfing Goat Dairy, just broke ground for phase two of his 43 kilowatt project, but he is pleased with phase one, which covers half his barn roof and was switched on a couple of weeks ago.
The project, designed and built by Haleakala Solar, cost more than $300,000, but after two tries Kafsack got a Renewable Energy for America grant from the Department of Agriculture to cover 20 percent of the cost.
Without the grant, he said Friday, the investment would not have made a sufficient return, but with it he will recover his costs “in under 10 years.” Continue reading
Subsidies for large-scale solar power installations are to be cut drastically, in a move that ministers said would preserve funds for households to put up panels, but industry warned would mean a slower uptake of renewable power.
The government said its long-awaited review of feed-in tariffs for renewable energy would divert funds from field-sized solar power plants to panels on house roofs.
But the renewable energy industry and green campaigners said the change of heart would mean community schemes, put forward by housing associations, schools and hospitals, would not go ahead.
Howard Johns, chairman of the Solar Trade Association, said the move would cripple the UK’s fledgling solar panel industry. “Crushing solar makes zero economic sense for UK plc because it will lose us major manufacturing opportunities, jobs and global competitiveness,” he said. “It also risks locking us in to more expensive energy options in future. It is inexplicable that the Treasury can be allowed to damage energy and industrial policy by taking decisions without taking into account the bigger picture.”
The reform, trailed in February but delayed by a consultation that was recently completed, will favour domestic and other small-scale installations of solar power, of up to 50kw – typically enough to cover several houses, or about two tennis courts according to the government, but not enough for some of the community-scale installations some developers had planned, which would cover fields.

First Wind LLC said it has temporarily idled the turbines at its Kahuku wind energy project while it works on the battery storage system.
The 12 wind turbines were shut down on May 22 and are expected to be brought back online in stages starting later this week, company spokesman John Lamontagne said in an email from the company’s headquarters in Massachusetts.
“We are conducting a diligent and thorough review of the operating issues for the battery facility at the Kahuku project. During that time, the project is offline,” he said.
The 30-megawatt project — Oahu’s only commercial-scale wind farm — began feeding electricity into Hawaiian Electric Co.’s grid in March. The turbines produce enough energy to power about 7,700 homes, according to First Wind. First Wind sells the electricity to HECO at a fixed price of 19.9 cents per kilowatt-hour under a 20-year purchase power agreement.
