Estonia: Utility-scale battery storage to stabilize the power grid

In view of the enormous expansion of renewable energies in all countries of the European Union with the aim of becoming CO2-neutral by 2050 and strengthening the EU's energy independence, energy storage is proving to be crucial: it enables the stabilization of the electricity grid by helping to regulate the balance between generation and consumption.

Evecon and Corsica Sole are joining forces in the Baltic Storage Platform joint venture to build and operate high-capacity battery storage power plants connected to the electricity transmission grid. The plants will be built at two locations and are scheduled to be commissioned in the course of 2025. The two projects have a total output of 200 megawatts and a total capacity of 400 megawatt hours.

Challenge decoupling the grid from Russia – crucial role of batteries

The connections for the future battery storage power plants will be built by Elering, the Estonian electricity grid operator. Construction of the first plant in Kiisa is scheduled to begin in spring 2024. Construction of the second plant in Arukulä in the last quarter of 2024.

The decoupling of the Baltic states from the Russian electricity grid, which has so far ensured the stability of the grid, is expected to take place at the beginning of 2025. The electricity system of the Baltic states will be weakened by the time it is decoupled from this grid and synchronized with the grid of the European continental plate. Batteries will play a crucial role in this transition period.

Contribution to sovereignty and energy security

Estonia is preparing for an unprecedented situation with the transition of its electricity grid. Announcing the projects in Tallinn, Kristen Michal, Estonian Minister of Energy and Environment, emphasized that the emergence of backup and storage capacity in Estonia is good news and that it is particularly welcome that it is being run by private companies.

Emmanuel Mignot, French Ambassador to Estonia, said that France is the country's second largest investor in the technical sector and that he welcomes the fact that a French company can make such a concrete contribution to the country's sovereignty and energy security. (hcn)
