Much of the country’s renewable energy supply is currently subject to double-digit rates of curtailment. This curtailment has been going on for quite some time, leaving many of China’s clean power systems seeing little use. It has also highlighted longstanding problems with the country’s aging energy infrastructure.
Under the old subsidy system, all projects qualified to receive a fixed rate for their power. The new one is designed to give the government more control of the capacity built and the cost of each new contract. ...According to the ratings agency India Ratings and Research, there could be a substantial dip in wind capacity additions in the current financial year ending March 31.
Yet even with double the wind capacity, China still produces less electricity from turbines when compared with the U.S. That’s because it’s installing lower-quality machines using less reliable breezes and doing so more quickly than the distribution grid can take in the flows.
Renowned biodiversity expert Dr. Rohan Pethiyagoda has questioned a poorly researched Initial Environment Examination Report (IEER) saying it poses a threat to the Vankalai Sanctuary near Mannar. ...He also says that the IEER provides almost no evidence that the unique natural heritage offered by the Vankalai Sanctuary will be preserved as a result of the project, especially with regard to bird life with the proposed transmission line. “This is a matter of urgent national importance and there needs to be a public debate on this plan."
Grid connectivity is not streamlined, so problems arise due to inconsistent supply from the windmills. Local industries blame them for disruptions in power supply, eventually resulting in damage to expensive equipment. While one can argue in favor of the little electricity these windmills produce, it remains to be seen how much loss has been incurred from their use of farm land, installation, and connectivity costs—and, of course, the costs of frequent disruptions from rain.
KEPCO initially projected that its investment in the wind power plants would generate a stable return of 6 percent to 7 percent per annum as the power plants had a 20-year long contract with the local electricity firms. However, the pre-feasibility study done by Korea Development Institute (KDI) on the request from the Korea’s Ministry of Strategy and Finance found that the investment would yield a mere 2 percent annual return.
"The main cause of idling turbines is an overcapacity in China's power generation," said Lin Boqiang, director of the China Center for Energy Economics Research at Xiamen University. "China's power supply currently surpasses its demand by 20 to 25 percent. All the electricity producers in the country are going through a tough time, and wind power developers are not an exception."
“One of the biggest reasons that natural gas, oil, and coal are the world’s most-used energy resources is because they are incredibly reliable,” Daniel Simmons, vice president for policy at IER, told The Daily Caller News Foundation. “By the same token, wind struggles to compete with conventional fuels because it is inherently unreliable.”
The 81-megawatt Caparispisan wind power project in Pagudud, Ilocos Norte resumed delivering power to consumers, after its operator built temporary towers to connect the plant to the Luzon grid.
Two transmission towers operated by wind farm developer UPC Renewables collapsed on Thursday night, following a large explosion, Pasuquin town mayor Peter Felix Aguinaldo said on Friday.
China’s wind farm operators have suffered from idled capacity for years as the rush to build projects in the windiest areas of the nation surpassed the grid’s ability to absorb and transmit the power.
With a sudden fall in wind energy production over the last two days and combined with outages faced by the state and central generating stations (CGS), power managers had to resort to load shedding in a few parts of the state.
As the Guam Power Authority expands it renewable energy portfolio with wind and solar capabilities, Consolidated Commission on Utilities chairman Joseph Duenas has doubts about the viability of a wind turbine project. He told KUAM News "They haven't started construction or any kind of work on the project and the project is supposed to be completed in eight months."
Wind power generators need vast, open land to provide adequate space between each windmill. On this small island, commercial-scale wind power plants might be tough to pull off, he said. And for a utility-scale wind power plant to be viable, there must be steady flow of winds — ranging from 12 mph to 28 mph — for efficiency, he said. Earthquakes and typhoons also add to the obstacles of windmill projects on the island.
About 43 percent of installed wind generation sat unused in the northeastern province of Jilin in the first six months, the highest rate in the nation, the NEA said in a statement on Monday. The northwestern regions of Gansu and Xinjiang followed.
A protest against the development of a wind power complex around Hanu Mountain and Maebong Mountain in Uiryeong County, Gyeongsangnam-do has been continuing for two weeks at the construction site. About 10 to 30 locals are occupying the site, delaying the construction. ...The committee is demanding that the company set standards for low-frequency noise and conduct simulations of possible landslide accidents.
While listed wind firms have seen their shares surge 18-38 percent this year, compared with a 17 percent rise on the broader Hang Seng index .HSI, some industry insiders are urging investors to rein in their enthusiasm. "I'm not entirely sure where the optimism came from," said an executive at top power producer Datang Power (0991.HK). ..."Overall electricity demand is very weak. It is unlikely wind power will outshine others."
If private entrepreneurs decide to exit the business when the feed-in tariff program ends, the nation is expected to be swamped with illegally dumped equipment and facilities. Disposing of gigantic windmills, for example, could pose a serious challenge to many wind-power entrepreneurs.
A protest action staged by a group of residents here marred the inauguration on Wednesday of the 81-megawatt Pagudpud wind farm that is operated by the North Luzon Renewable Energy Corp. (NLREC).
Authorities are trying to cut manufacturing scope in green-energy industries after overproduction caused equipment prices to tumble. Shang Fulin, chairman of the China Banking Regulatory Commission, said in March it will seek to limit lending that worsens overcapacity. The wind-turbine and solar-power industries face “relatively large pressure” from excessive production ability.
