Grid operator Fluvius wants to invest an additional 4 billion in electricity grids

Grid company Fluvius wants to invest an additional 4 billion in the Flemish distribution networks for electricity between next year and 2032. To ensure that by 2030 we can continue to smoothly accommodate up to 1.5 million electric cars, massive numbers of heat pumps and solar panels, and rising consumption in industry, Fluvius is proposing to reinforce 40 percent of the low-voltage grid, 13 percent of the medium-voltage grid, and one-third of the distribution cabins that distribute power in the streets over the next ten years. Investments in the gas grid will then be phased out over the next decade.
