At Ores, the prosumer tariff will increase by 31% in 2025, from 62.45 euros to 82.04 euros per kW. An average photovoltaic installation making 5 kW, the price therefore increases from 312 euros to 410 euros per year.
At Resa, the prosumer tariff will increase by 22% in 2025, from 66.67 euros to 81.07 euros per kW. For an average installation, the price therefore increases from 333 euros to 405 euros per year.

At AIESH, the increase is 19%, from 77.52 euros to 92.15 euros per kW. The prosumer will therefore pay 460 euros, for an average installation. Finally, at the Régie de Wavre, the price increases by 18%, from 71.94 euros to 84.82 euros.
According to Cwape, the proportionally greater increase in the prosumer tariff, compared to the increase in the distribution tariff, is explained by the fact that the prosumer tariff directly incorporates the tariffs of Elia, the high voltage network manager.
