Soltech Energy Solutions is installing a 12MW/12MWh battery storage unit in Sweden for municipal energy firm Nybro Energi, set to come online before the end of the year.

The clean energy solutions arm of energy firm Soltech Group will deploy the one-hour system for Nybro Energi. The project is set to reach commercial operation date (COD) in the fourth quarter of 2023, a spokesperson for Soltech told Energy-Storage.news.

The battery energy storage system (BESS) will mainly provide frequency regulation services to transmission system operator (TSO) Svenska Kraftnät, but in future may also provide power to the grid during times of high demand, they added.

Nybro Energi will be the project owner. Its CEO Håkan Dahlgren commented on the announcement: “We are among the first energy companies in Sweden to invest in a large-scale battery storage of this kind. We see there is a market for these solutions and there will be a need to store energy and to stabilize the grid, when we are getting more and more renewable sources.”

Soltech Energy Solutions has been active in the Swedish battery storage market recently, last year announcing 2MW projects for an EV truck charging park (Scania) and a solar PV plant (Alight). In September it revealed another project at a solar PV plant but did not reveal the buyer or details about the project size, only saying it was a SEK 15 million order (US$1.4 million).

The country’s market has been picking up lately with frequency new project announcements, as BESS projects increasingly provide the flexibility services which were previously exclusively done by Sweden’s hydroelectric portfolio.

The latest was a 20MW/20MWh project acquired by Switzerland’s largest energy firm Axpo, set to come online next year. Developer Ingrid Capacity, interviewed whilst at Energy Storage Summit 2023 in London in February, estimated some 100-200MW of BESS would come online in Sweden this year.

“We are very happy to help Nybro Energi with a tech solution that stabilizes the regional electricity grid. The battery storage will contribute with frequency services, cost optimization and will cut the power peaks that the increased electrification brings. This is a scalable future investment that will create great benefits onwards,” said Rickard Lantz, Business Development Manager, Soltech Energy Solutions.
