Some possibly relevant context: the electricity supply in Belgium has very little reserve during peak demand periods in winter. The probability of a large blackout has been growing year after year. The government has prepared a "disconnection plan" with controlled rolling blackouts of different regions to avoid a total blackout: https://economie.fgov.be/nl/themas/energie/bevoorradingszeke...

As a result, reducing the electricity supply further is currently politically impossible.
