What the sources say

NTR (30 Apr 2025): construction to begin within weeks, completion estimated by mid-2026. NTR (18 Nov 2025) still called it under development; no completion news on NTR's site on 12 Oct 2026. OX2 sold it as 50 MW / 110 MWh (Energy-Storage.news, Aug 2024); NTR states 55 MW / 110 MWh. Capalo AI optimises.

Evidence and sources

From the owners’, developers’ and builders’ own releases, council decisions and permit bulletins, read by Vitreous and checked against the owners’ own words on 12 October 2026; a bracket such as “(Energy-Storage.news only)” in a field means the trade press is still the only source for it. Fingrid publishes no meter, no price and no instruction per battery, so this page carries no money: what one megawatt is paid in Fingrid’s markets is on the markets page, for the whole market and never for a named battery. List id FI-B029.
