What the sources say
Capalo AI (14 Dec 2023): Lempäälän Energia chose it as "market optimization partner for its 4 MW BESS" in the LEMENE microgrid, which "can operate as an islanded network thanks to the battery". No later source says it still runs; the start date is not stated. The trade register shows Lempäälän Energia Oy (0150764-7) ended on 1 Jan 2025 and Lempäälän Lämpö Oy (0150718-8) trading as Lempäälän Energia since 15 Jan 2025. Not Taaleri's 30 MW Lempäälä battery nor Merus Power's test unit. From the Vitreous Nordic feed of 26 Oct 2026, checked 27 Oct 2026.
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.
