Evidence and sources

From owners’, developers’ and builders’ own releases and municipal and environmental permits, read by Vitreous; where a field rests on the trade press alone, the notes say so. Energinet publishes no meter, no price and no instruction per battery, so this page carries no money: what one megawatt is paid in Energinet’s markets is on the markets page, for the whole market and never for a named battery. The nearest transmission station is the nearest by distance on Energinet’s capacity map; where the battery actually connects is not published. List id DK-B036.
