Germany-based EV charging and BESS integrator ADS-TEC Energy has installed eight units comprising a 20MW battery energy storage system (BESS) in Sweden.
The large-scale storage containers have been deployed for project developer Polar Structure AB, in Haninge, near Stockholm last month. It is co-owned by Polar Structure subsidiary Polar Capacity and Stockholm Exergi, the utility for the capital.

The BESS, for which the MWh capacity wasn’t revealed, will provide grid-supporting ancillary services as well as “store and distribute sustainably generated energy”, the announcement said. Stockholm Exergi will operate the BESS.
ADS-TEC claimed the project is the most powerful modular large-scale storage solution in Sweden, though the announcement didn’t specifically say it had entered commercial operation. There would typically be a gap of a few months between physical installation of BESS units and full commercial operation to allow for testing and commissioning.
Energy-Storage.news has asked the company to comment and will update this article if and when a response is received.
A larger, 40MW project that system integrator Nidec ASI is building for international independent power producer (IPP) Neoen should be coming online soon, with the start of construction announced in January 2023.
That was the first of a flurry of large-scale projects announced over the course of 2023 so far in Sweden, some of which are early-stage (like two from developer SENS in October and September) or set to come online next year.
Developers and operators are looking to capitalise on high prices in ancillary service markets across the Nordic energy market, something pan-Nordic optimiser Capalo AI recently discussed with Energy-Storage.news.
