What the sources say
Cactos (6 Feb 2025): 24 units, 5 MW / 10 MWh, commercial operation in January 2025. ESS News gave 24 January 2025 and said Cactos sold its whole stake at the start of operation; Cactos's own release says neither, so the day is not used and the stake sale is unconfirmed.

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.
