Netherlands-based developer Giga Storage has secured the irrevocable permit for a 600 MW / 2,400 MWh battery energy storage system (BESS) in Belgium — the largest single battery storage project approved in Europe to date. The four-hour-duration system is aimed squarely at grid congestion relief and ancillary services.
The approval marks a step-change in scale for the Belgian market, which has so far been dominated by smaller distributed and behind-the-meter systems. A 2,400 MWh plant can discharge at full 600 MW output for roughly four hours, long enough to cover the evening demand ramp when solar output collapses.
Belgium’s appeal for large-scale storage rests on a combination of factors: a congested transmission network around the Antwerp-Brussels axis, a fast-growing offshore wind pipeline that needs buffering, and a market design that increasingly rewards flexibility services.
For C&I buyers, the project matters indirectly: grid-scale storage competes for the same flexibility revenue pools that behind-the-meter assets increasingly target, and its arrival signals where Belgian grid operators expect congestion to be worst over the coming decade.
