Dutch open ‘world’s largest offshore’ wind farm

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

The first U.S. offshore wind farm just shut down a diesel plant

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.

Wind Energy Now Directly Competing With Coal On Cost

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.

Wildlife friendly windmill

Royal Society for Protection of Birds (RSPB)
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.

Giant wind turbine sets record

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 power briefly sets record as source for electricity in U.S.

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.

Denmark Generated Enough Wind Energy To Power All Its Electricity Needs On Wednesday

According to WindEurope, Denmark generated a total of 70 gigawatt-hours (GWh) from onshore wind and another 27 GWh from offshore wind — enough to power the equivalent of 10 million average EU households. This is not the first time wind power has dominated generation statistics in Denmark, with several big wind energy days back throughout 2015. By the end of 2015, the country had a total of just over 5 gigawatts (GW) worth of wind energy installed — made up of 3799 megawatts (MW) of onshore wind and 1271 MW of offshore wind — a number which likely would have increased during 2016.
