About Exaum
Exaum builds grid-balancing equipment and software that help keep electricity supply and demand in equilibrium. Its "grid brake" hardware absorbs surplus energy during imbalance events in under a second, and its bidding software forecasts market conditions and automates bids for balancing products.
Its main customers are transmission system operators, to whom Exaum provides 24/7 available reserve capacity as a grid balancing service. The company also seeks partnerships with power producers and energy-intensive industry players.
Exaum was founded in 2021 and is headquartered in Tampere, Finland, where it designs and manufactures its hardware.
Product: Modular grid-brake hardware for absorbing surplus grid energy, plus bidding software that automates balancing-market bids and reserve capacity service.
