But no definite way to solve the problem is in sight and operators of these windmills are struggling to cope with lightning-caused breakdowns that threaten their operations. On Oct. 2, a fire broke out at the Sarakitomanai wind farm in Wakkanai.
The ceremony, to commemorate the installation of the turbine, was disrupted when the arm of the 1,000-ton crane, toppled and fell down suddenly in a trial operation to lift a wind turbine.
Jiuquan City in Gansu, a crane owned by Sinovel Technology (Gansu) Ltd. collapsed killing five people and injuring another. Jiuquan City Information Office informed the media of the accident.
Three fire engines arrived at the scene, but after surprisingly discovering that their hoses were too short to reach the 66-meter-high wind turbine, they remained on site until the fire extinguished itself in about four hours.
Tokyo Electric Power Company (TEPCO) is limiting generation from renewable plants (including wind) to 5% of their installed capacity. ...Hokkaido Electric Company [is] also capping wind farm contributions to 5% of their capacity. In addition, Arakawa acknowledged that "small [wind farms] across the country are disconnected" and that these are unlikely to rejoin the electricity network until the nuclear crisis is stabilized.
Three workers have been killed while installing and testing a Sinovel wind turbine in northern China. ...The accident follows a recent announcement by China's National Energy Bureau (NEB) that it is launching an investigation into whether cost cutting has led to a fall in safety standards.
"At present, no one is willing to speak publicly about the problems of wind turbines. This is unfavorable to solving the problem. Actually, foreign turbines met similar problems when they entered the Chinese market. By investigating the quality of wind turbines, NEB is facing the problem."
The strong winds that buffeted the Tokai and Kanto regions Tuesday apparently snapped the massive blades of two wind turbines ...Each windmill is 103.5 meters tall, and can generate 1,500 kilowatts. Turbines No. 4 and No. 5 each lost one of their three 37-meter-long blades.
In what implies a Rs.1 billion ($25 million) hit on its balance sheet for the current quarter, leading wind power equipment-maker Suzlon Energy will refit wind turbine blades for a project in the US, the company said Monday. “The company will do a retrofit programme to resolve blade-cracking issues discovered during the operations of some of its S88 turbines in the US,” the company informed the Bombay Stock Exchange Monday.
A wind turbine set up in March 2006 was touted as the answer to energy problems in Iga, Mie Prefecture. The clean energy would supplement the power supply for radio relay facilities of a land ministry office that records water levels of the upper reaches of the Kizugawa river. But there was one problem. The wind turbine fell apart in less than two years. Malfunctions and accidents involving wind turbines have occurred repeatedly across the country, leading to suspended services and even the scrapping of one facility. Amid rising oil prices, wind power generation is gaining attention as a means to use limitless natural energy. However, slipshod surveys of wind, flawed designs or sheer incompetence have dealt a blow to the reputation of wind turbines, which are easier and cheaper to construct than other electric power generation facilities.
HIGASHIDORI, Aomori Prefecture–The industry ministry Wednesday said it is trying to determine what caused a 68-meter-high wind turbine to collapse earlier this week since strong winds apparently were not blowing at the time. The incident at the Iwaya Wind Farm in the Iwaya district of Higashidori in this northern prefecture is thought to have occurred late Monday, according to officials of Eurus Energy Holdings Corp., which manages the wind farm. While no one was injured, the incident resulted in temporary power outages to homes in the area because power lines were severed.
A compilation as of November 1, 2006 of turbine accidents in the USA and abroad by accident type, date, site, state/country and turbine model.
Police said the wind turbine generator of the unit exploded last night and caught fire. The splinters from the turbine, located a few kms from the Koodankulam Nuclear Power project site, spread over one sq km after the explosion.
Coimbatore: With the Indian Air Force expressing concern over the safety of aircraft, while landing and taking off, due to tall structures, including windmills in the vicinity of Sulur Airport, Indian Wind Power Association (IWPA) has appealed to its members to paint the mills in red and white patterns.
This paper examines the damages of all six operating wind turbines on Miyakojima Island by Typhoon Maemi on September 11, 2003.
Typhoon Maemi struck Miyakojima Island on September 11, 2003 with an average wind speed of 38.4m/s and a maximum gust of 74.1m/s, recorded at Miyakojima meteorological station. All six wind turbines operated by Okinawa Electric Power Company were extensively damaged. Two Micon M750/400kW turbines collapsed by the buckling of the towers and one Enercon E40/500kW turbine turned over due to the destruction of the foundation. The other three experienced broken blades and damaged nacelle covers.
