The planet’s biggest and most powerful wind turbines have begun generating electricity off the Liverpool coast, cementing Britain’s reputation as a world leader in the technology. Danish company Dong Energy has just finished installing 195m-tall 32 turbines in Liverpool Bay that are taller than the Gherkin skyscraper, with blades longer than nine London buses. The project is the first time the 8MW turbines have been commercially used anywhere in the world. Collectively they now have a capacity of 5.3GW, generating enough electricity to power 4.3m homes.

Dutch officials on Monday opened what is being billed as one of the world’s largest offshore wind farms, with 150 turbines spinning in action far out in the North Sea. At full winds the Gemini windpark has a generating capacity of some 600 megawatts, and will help supply some 785,000 Dutch households with renewable energy, the company said. Gemini will contribute about 13 percent of the country’s total renewable energy supply, and about 25 percent of its wind power

America’s first offshore wind farm just helped to shut down a small diesel-fired electric power plant on Block Island, Rhode Island. Block Island officials on Monday switched on a connection between the island and a cable linking the wind farm to Rhode Island’s mainland power grid. The connection allowed the island’s only electricity source — a small diesel-fueled power plant — to shut down. The island’s 2,000 residents burned about 1 million gallons of diesel fuel annually.

Last week, Xcel Energy announced a multi-state wind capacity project, anticipated to be the largest in the United States. Spanning seven states, the project covers eleven new wind farms and would generate 3280 MWs at a cost of $3.5-4.4 billion. In its announcement, Xcel emphasized the cost-savings attached to wind power, arguing that it would save Xcel customers in the Midwest $7.9 billion over thirty years. This, rather than the environmental benefits of renewable energy, drove the company’s mission statement: wind was cheap, not just clean.
Moody’s Investor Services now estimates that the falling costs of wind power directly threatens 56 GW of coal power, out of 87 GW surveyed. Moody’s report estimates the MW-hour cost of wind in the Great Plains region at around $20, while coal comes in at $30.

those bats are only likely to be in-flight around dawn and dusk at wind speeds between 2 and 5 meters per second—so Ecotricity and RSPB implemented a mitigation plan by which the turbine is shut off for half an hour before and after dusk, whenever wind speeds are below 7 meters per second.
The new V164 9 MW turbine from Danish company MHI Vestas Offshore Wind produced an amazing 216,000 kWh on December 1, 2016. The turbine was installed at a testing site near Østerild, Denmark. The 9 MW V164 turbine is a tweaked and upgraded version of the 8 MW V164 that was developed in 2012. The V164 has been the most powerful wind turbine to date, holding the previous wind energy generation record before its upgrade. It stands 722 feet high and has blades that are 263 feet long. The V164 has a 25-year life span and 80 percent of the turbine can be recycled when its job is done.

Wind briefly powered more than 50 percent of electric demand on Sunday, the 14-state Southwest Power Pool (SPP) said, for the first time on any North American power grid. Wind power in the SPP region has grown significantly to over 16,000 MW currently from less than 400 megawatts in the early 2000s and is expected to continue growing. One megawatt can power about 1,000 homes.
Wind power briefly reached 52.1 percent at 4:30 a.m. local time on Sunday, SPP said on Monday, beating the previous penetration milestone of 49.2 percent. Wind penetration is a measure of the amount of total load served by wind at a given time.
