10 March 2026, 15:30 | Regulatory press release

Sustainable Energy Solutions Sweden Holding AB ("SENS" or the "Company") today achieves an important milestone with the completion of the sale of the 85 MW BESS project in Pyhäsalmi. All conditions for the transaction have been fulfilled and Prime Capital AG, a Frankfurt-based infrastructure investor, has today acquired the shares in the project company (SPV). The total purchase price is approximately EUR 5.5 million. In addition to the initial purchase price, there is a profit sharing during the period up to and including July 2027, which is dependent on the project being completed before this date. SENS' ownership in the divested project company amounted to 55 percent.

"The completion of this transaction is proof that our strategy to develop larger BESS projects in attractive locations is working. With this divestment, we strengthen our position as a leading project developer of large-scale energy storage. The sale also gives us the financial muscle to further develop our project portfolio and realize additional value. I would like to thank everyone involved for a well-executed deal." says Anders Björkenbo, CEO of SENS.

On 19 January 2026, SENS announced that a share purchase agreement had been signed with a Frankfurt-based infrastructure investor, Prime Capital AG. The transaction was subject to customary conditions, which have now been met. The buyer has thereby acquired 100 percent of the shares in the project company (SPV).

The project company was 55 per cent owned by SENS and 45 per cent by Dovre Group Oyj. The total purchase price is approximately EUR 5.5 million. Revenue from the sale will be reported in the first quarter of 2026 and will be reflected in the upcoming interim report. Any profit sharing from the project will be reported in the quarters in which it is paid.

The BESS project in Pyhäsalmi is part of the energy cluster that SENS has been developing for a long time at the Pyhäsalmi mine in Finland. The project is designed to deliver capacity to both the frequency regulation and arbitrage markets in Finland. With a storage capacity of 85 MW / 170 MWh, the plant will contribute to increased flexibility and stability in the Finnish electricity system.
