Germany’s four power grid operators said on Friday that a sharp rise in the country’s renewable generation capacity was needed over the next 15 years to meet demand from the electrification of heating, transport and other industries. Presenting their capacity planning needs through 2035, the four high voltage transmission grid firms (TSOs) said in a press release that Europe’s biggest economy will need installed renewable power capacity of between 235 and 276 gigawatts (GW) by 2035 compared with 118 GW in 2018.

“The power sector plays a central role in reaching climate targets and this is coupled with a significant expansion of renewable energy,” the TSOs said, adding that all the scenarios they had discussed assumed increasing power demand, according to Reuters.

The forecast was based on power usage projections of between 638 and 729 terawatt hours (TWh) by the end of the period, compared with 595 TWh consumed in 2018.
