Estonian renewables developer, Evecon, has joined forces with France's Corsica Sole to embark on a significant initiative aimed at strengthening Estonia's energy independence by installing two battery energy storage systems with a combined capacity of 200 MW/400 MWh.
The planned facilities, named Arukula and Kiisa, are set to be situated in Harju County in northern Estonia, with an anticipated operational timeline of 2025. This strategic move aligns with Estonia's broader objective of decoupling from the Russian power grid. The commissioning of these storage systems is scheduled to coincide with the synchronized disconnection of Estonia, Latvia, and Lithuania from the Russian electricity grid, aligning them with the European network.
Operated through the Baltic Storage Platform, this collaborative effort establishes a joint venture with Evecon holding a 20% stake and Corsica Sole as the controlling owner with an 80% share.
The two battery systems, each with a capacity of 100 MW, are designed to discharge electricity equivalent to the needs of approximately 90,000 homes. Beyond contributing to grid stability by managing fluctuations, the installations will also serve as a crucial emergency reserve. Arukula and Kiisa are slated to be operational in the second and third quarters of 2025, marking a significant step towards bolstering Estonia's energy resilience.
Pioneering geotechnical studies for this ambitious project were conducted by Pinnaseuuringud OU, laying the groundwork for the successful implementation of these vital energy storage facilities.
