Technical FAQs 4

Where is Estonia's largest battery storage facility located?

The flagship battery storage project commenced operations on February 1, only days before cutting ties with the Russian power grid. Estonian state-owned energy company Eesti Energia has inaugurated the nation’s largest battery energy storage facility at the Auvere industrial complex in Ida-Viru County.

How will a battery energy storage park work in Estonia?

The battery energy storage park and its substation will be connected to the electricity transmission network using a 330kV AC underground cable, marking a first in Estonia. Baltic Storage Platform confirmed that the BESS will seek to ensure the stability and resilience of the Estonian electricity grid.

Why is energy storage important for Estonia?

Energy storage is also vital for meeting Estonia’s goal of sourcing all its electricity from renewable sources by 2030. The country’s climate minister, Yoko Alender, emphasised the role of storage systems in this transition, saying they would help ensure a “clean, reliable and affordable energy future” for Estonia.

Should Estonia invest in battery parks?

Estonia’s investment in large-scale battery parks highlights its strategic push for both energy independence and a more sustainable power grid. However, battery parks do have environmental impacts.
