The Guardian | National Grid fires up coal power station for first time in 55 days

National Grid has fired up a coal-fired power station for the first time in 55 days after Britain’s record-breaking heatwave brought wind turbines to a near-standstill and caused gas-fired power stations to struggle.

Gas plants can struggle to produce electricity at normal levels during high temperatures, according to experts at the energy data company EnAppSys, and it is normal for their power output to fall during heatwaves. They rely on a steady flow of air through its compressor, according to the energy technology firm Wartsila. It takes more energy to compress hot, humid air to the same mass as air which is cooler and drier, so many power plants become less efficient as the outside temperature rises.

I feel solidarity with the power stations finding it too hard to do anything today.
