The state of California did so well at producing solar energy last month prices turned negative.

Figures released by the US Energy Information Administration (EIA) reveal that on 11 March the state generated so much power from the sun that, twinned with the fact non-renewable energy was still feeding into the grid, wholesale prices turned to zero and even to negative.

“In March, during the hours of 8:00 a.m. to 2:00 p.m., system average hourly prices were frequently at or below $0 per megawatthour (MWh).” the EIA said.

While Californians won’t enjoy an immediate windfall, as bills are calculated by averaging things out over a month, it demonstrates the direction of travel is towards cheaper electricity with renewable energy.
