Fever Energy AB
Enabling energy companies to aggregate, optimize, and monetize distributed energy assets—such as batteries, EVs, HVACs, and solar panels
About Fever Energy AB
Fever Energy is an energy flexibility platform that lets utilities and energy retailers aggregate home batteries, EVs, solar and heat pumps as home energy management systems as a service into their own virtual power plant, and trade that flexibility in balancing markets. Fever Energy enables both front-of-the-meter and behind-the-meter optimisation at the same time, for both commercial and residential sites.
Energy companies use Fever Energy to launch flexibility services for their customers under their own brand. The platform connects to customers' devices, forecasts and optimises their flexibility, and trades it in the European balancing markets. Energy companies keep the customer relationship.
Fever Energy is live in Sweden (FCR-D, FCR-N, FFR, aFRR, mFRR, intraday, day ahead), Denmark (FCR-D, FCR-N, aFRR, mFRR) and Finland (FCR-N, FCR-D, intraday, day ahead, mFRR), with more than 600 MWh of assets under management. In September 2026, Vattenfall launched its smart steering service Nätverka Batteri on the Fever Energy platform. Fever Energy was ranked #6 on Sifted 100: Nordics 2026.
Fever Energy AB was founded in 2022 and is based in Stockholm, Sweden.
