Energy supply of the future

Whitsunday last year showed that the amount of electrical power generated solely by wind and sun is able to cover the entire demand of Germany. An important role in the future supply of electrical power plays eCAPITAL’s portfolio company sonnen GmbH in Wildpoldsried.

sonnen successfully produces storage systems for private households, links them together to form a decentralized virtual power plant and thereby produces a self-supporting energy community which manages its power demands completely without conventional suppliers. Sonnen’s disruptive approach has not only been awarded numerous prizes by industry experts (e.g. Bloomberg New Energy Pioneer, 50 Smartest Companies MIT Technology Review, Zayed Future Energy Prize), in the beginning of 2017 it also draws attention from the media as can be seen by notable publications in the newspaper FAZ on January 23rd, in the magazine CAPITAL and in the magazine Handelsblatt focusing on the special topic “Energy Industry 4.0”.
