Investment decision on Skarta Energy’s battery solution for the Utajärvi solar park

Skarta Energy’s solar park under construction in Utajärvi will have a 20 MW (40 MWh) battery solution. The implementation of the battery solution for the Isosuo hybrid power plant has been agreed with NYAB, which has also acted as the EPC operator. Installation work will begin immediately, and the battery will be ready for use in June 2026.

The production of solar energy depends on weather conditions, so balancing elements are needed to store excess energy and keep the electricity system in balance.

"As a developer and builder of solar power, Skarta Energy plans and implements projects in which battery storage facilities are combined into a whole. Each new solar farm is considering adding battery storage, and in the future, each solar farm is likely to be a hybrid solution with solar panels and batteries working in parallel. This helps to store solar energy when production is at its highest and utilize it later," says Arttu Niemelä, Energy Market Specialist.

The Isosuo battery solution will be installed next to the Utajärvi substation and will be implemented by NYAB.

"This is a very great continuation of the Utajärvi solar park project, as we will also be able to build a battery storage facility in the area. We are happy to be able to utilize our solid expertise in battery solutions in an already familiar environment and to continue our good cooperation with Skarta Energy," says Pauli Lahti, Sales Manager of NYAB's electricity network business, and Antti Keskinen, Director, Electrical grids.

"NYAB has been responsible for the construction of the park and our cooperation has been very smooth. It was natural that they would also implement a battery solution for us," says Simo Rintakari, Project Manager.
