What the sources say
CONFIRMED 12 Oct 2026 (was an inference): Dovre (19 Jan 2026) and SENS (10 Mar 2026) say Prime Capital AG bought 100% of Pyhäsalmi BESS Oy, 85 MW / 170 MWh, in Pyhäjärvi next to the closed Pyhäsalmi mine, ready to build since late 2025; the sellers get more if production starts by 1 July 2027.

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.
