A Swedish utility plans to test a grid-connected system of batteries that stores wind energy during times of low demand and better balance electricity loads. “The battery will store wind energy produced during the night when demand is low and distribute it to users during the day,” says Falbygdens Energi CEO Lars Ohlsson. The utility also plans to explore how stored energy can support an electric-car infrastructure. Falbygdens Energi is working with the power and automation technology group ABB to deploy a dynamic energy-storage device on its power distribution network. The battery system will be installed as part of an existing substation in the city of Falköping and will store locally produced energy from wind turbines. Storage capacity will be 75 kW in cycles of up to 60 minutes.
It will be the first such low-voltage dynamic storage system of its kind in the country. The project is part of a partnership agreement in which Falbygdens Energi and ABB will work together to collaborate on develop technologies for integrating renewable energy and building smarter grids.
