In May 2024, SENS entered into a principal agreement with Callio Pyhäjärvi, a Finnish multidisciplinary development company, to provide the technical solutions to develop an energy storage solution at the Pyhäsalmi mine in Finland. With today's acquisition, SENS secures full ownership of two of the key sub-projects within this partnership: an 85 MW battery storage system (BESS) and a 75 MW underground pumped storage facility (UPHS). Both projects already have ready-to-build status, and following the acquisition the projects will move forward towards completion on different time-scales with the help of several investors an our aim is to fully finance both projects within a short time frame.

The BESS project, which is now ready to start the construction phase, is expected to be operational by 2025 and will supply capacity to both the frequency and arbitrage markets. This will enable fast revenue streams by utilizing already existing infrastructure.

The underground pumped storage power plant will utilize the existing Pyhäsalmi mine structure and its synchronized energy storage system. With a storage capacity of 530 MWh and a maximum output of 75 MW, the plant is designed to balance energy supply and demand. Furthermore, with this acquisition, SENS enables the opportunity to utilize the €26,3 million subsidy, which was granted to the UPHS investment from the Ministry of Economic Affairs and Employment (MEAE) of Finland in September 2021.

The ambition is to have a consortium for financing in place end 2024, with construction commencing during 2025.
