35 of 35 batteries drawn: 13 at the site itself, where OpenStreetMap has it mapped, the rest at the place their source names or the centre of their municipality, from GeoNames. Yellow is scheduled by Elia or running; blue is being built; pale blue is announced; grey has no confirmed start.

Every line of 110 kV and up as OpenStreetMap maps it (2,485 lines, 292 substations, 284 more with no voltage mapped left out), read 2026-10-20; the highest voltages at every zoom, the 110 kV web and the substations when zoomed in. Mapped by volunteers from imagery and operators’ maps, so a line can be missing. OpenStreetMap contributors, ODbL.

Belgium · the batteries Elia schedules, and the rest · Elia’s list of 20 October 2026

Elia schedules 14 batteries in Belgium, 828 MW. Another 1,720 MW is being built, and 946 MW of it is due by the end of 2027.

Elia, the grid operator, publishes every day the list of the units it schedules, and the batteries in it are named. That list is the backbone of this map: each battery in it is joined to its owner’s and builder’s own words. Batteries Elia does not schedule, mostly those on the distribution grids, are added from their owners’ releases, and so are the ones being built and announced. 35 batteries in all, every fact with its source. The Belgium page reads Elia’s list day by day and the meter on the largest; every battery has a page.

Every battery named, a megawatt and up

Largest first. Click a row to centre the map on the battery, or open its page for every fact and its source. Power and capacity are as the owner or builder stated them; Elia’s own figure, where it differs, is on the battery’s page. The date is the owner’s stated start, actual for a running battery and expected for the rest. A blank means no source gave it.
