Relletinsuo battery storage and substation
Announced, 30 MW, in Siikajoki. Every fact below is as a published source states it, with the address beside it; a field not shown is one no source gave, and nothing is guessed.

Who is behind it

Not published anywhere we have found: owner, ultimate owner, developer, built by, cells. The page says so rather than guessing.
What the sources say
Lupapiste public bulletin LP-748-2026-00069: building permit (rakentamislupa) given 8 Sep 2026 for a 30 MW battery storage area, 24 battery containers, 12 transformer containers, a substation and a 124 m2 control building. A placement permit for a "battery storage area" at Relletinsuo (LP-748-2026-00057, 31 Aug 2026) sits about 3 km west.
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.
