Wind power in the U.K. rose to a record, leading operators from RWE AG to SSE Plc to halt more expensive gas-fired power generation plants.
Wind output rose to as much as 6,053 megawatts at 2:10 p.m. London time today, beating a previous record on Sept. 15 and accounting for 14 percent of total supply, according to National Grid Plc data on Bloomberg. Generators halted 7,872 megawatts of gas-fired plants since yesterday, grid data show.
The U.K. plans to almost triple the amount of wind capacity by 2020 as it seeks to meet a target to get 15 percent of power demand from renewable energy sources. Wind and solar have no fuel costs, generally making them cheaper than coal or gas.
“As well as the higher wind power, demand is down by about 2 gigawatts from yesterday as well so it has given the chance for less efficient gas-burn facilities to drop output,” Gary Hornby, energy markets analyst at Inenco Group Ltd., said by e- mail today.
Wind may generate an average of 5,301 megawatts for the rest of today, 5 percent more than yesterday, according to Bloomberg’s wind model at 16:55 a.m.
Power demand is forecast to peak at 49,902 megawatts at 5 p.m. today, 6 percent less than yesterday’s maximum of 52,815 megawatts, according to National Grid data. Gas was generating 14,064 megawatts of power at 5 p.m., compared with 21,803 megawatts at the same time yesterday, grid data show.
