Who owns Finland’s named batteries

61 owners named across the 89 batteries, as the owners themselves state it in their releases; where a fund owns a battery the fund is named and its manager noted. Fingrid publishes no ownership, so this is the owners’ own word and nothing more, and it covers the named fifth of Fingrid’s count only.
