What the sources say
Neoen owns it in full and runs it, and sells reserve to Svenska kraftnät (Neoen, 31 January 2024). Neoen's release of 3 September 2025 on its Hultsfred wind farm lists Isbillen among its operating Swedish assets; no commissioning release of its own was found, so the year is the start Neoen gave. The Green Power Sweden list (energi.se, 28 January 2026) gives the owner as "Neoen/Alight"; no Neoen source says Alight holds a share.

Svenska kraftnät publishes no meter, no price and no instruction per battery, so this page carries no money: what one megawatt is paid in each reserve market is on the markets page, for the market as a whole.
