What the sources say

Both figures are for the whole battery and flywheel system: 10 MW (9 MW frequency control, 1 MW load shifting) and about 9 MWh. The battery share alone is not published. Dijk en Waard is my placement of Heerhugowaard (merged municipality since 2022). New in this round.

Evidence and sources

From the owners’, developers’ and builders’ own releases, grid operators’ and permit notices and the trade press, read by Vitreous. No Dutch body publishes a meter, an instruction or a payment for a named battery, so this page carries none. List id NL-B51.
