JAPAN: A government department has recommended larger wind turbines have safety checks on a more regular basis due to recent failures in typhoon season.
“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.
This paper examines the impact of wind turbine noise among wind farm workers. Turbine noise.can affect annoyance, sleep and health, and any disorder in these factors can amplify the sound exposure effects in the people living close to wind turbines. The effect of the noise exposure on the annoyance, sleep disturbance and health of the people living near to wind farms and their mutual effects on each other was studied in various places around the world and there is a comprehensive literature in this area [6–8], but, so far no study has been conducted to investigate these relations among wind farm workers. The abstract and background for the study are provided below. The full report can be accessed at the links on this page.
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.
The state-owned Taiwan Power Company (台電公司) has formed a committee to examine why seven of its wind turbines collapsed during Typhoon Soudelor last weekend, a Taipower official said Wednesday.
The state-run energy supplier said the typhoon's powerful gusts of up to 202 to 220 kilometers per hour blew six of its 18 wind turbines at Taichung's Gaomei wetlands to the ground and severely damaged two of its six turbines in northern Taiwan's Shimen Wind Power Station.
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.
Solar and wind power generation are too unstable and costly to provide more than marginal power generation capacity, especially given the need to extend power grids from major cities like Tokyo to more remote areas considered most suitable for wind power, he says.
Panchayat secretary Nithin Kailas told The Hindu that all the windmill towers had been installed without permission from the local body. No tax was paid to the government since they were set up. As per rules, each wind power generating unit had to pay Rs.70,000 as annual tax. As each unit occupied 120 sq m, they would have to pay land tax too.
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."
"When the matter reached court, where the verdict was in my favour, I asked the company to vacate the land. However, instead of doing that, I have been harassed by the company's agents who filed many police and court complaints against me," Varagiya's letter to the Collector stated.
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.
Like other countries that have promoted the technology with generous state support, Japan is also struggling with the financial and technical consequences of its rapid solar growth. Solar power here is costly for consumers because of high state-mandated prices, and handling the fluctuating output of thousands of mostly small solar producers is tricky for utilities. Necessary improvements in the infrastructure have not kept pace, experts say.
Apart from a passing mention of the Ministry of New and Renewable Energy’s well-publicised target of 1.75 lakh MW (175,000 MW) of renewable energy capacity, the Budget had absolutely nothing for the sector. The target and the commitments were increasingly seen as unrealistic. The industry had been hoping that some measures would have demonstrated that the targets were not just hot air.
