In developing the prosumer tariff (falsely called tariff but it is a tax), the CWAPE limited itself to taking over in full, like a copy and paste, the “network costs” part of the price per kWh invoiced to consumers, by ultimately and erratically putting prosumers on the same footing as ordinary consumers, which, on top of that, […]
The Walloon Region (French-speaking part of Belgium) has implemented a retroactive prosumer tax for all solar photovoltaic installations in Wallonia. This tax concerns more than 150 installations and at the rate of a fixed floor price of € 000 to € 200 per year for a 300 kWp installation, it weighs more than […]
The prosumer tax, falsely and fraudulently called the prosumer tariff, is a fixed part tax (from 200 to 300 € per year depending on your GRD on a basis of 3 kWp) and variable on all photovoltaic installations in Wallonia. And it is because there is an incompressible fixed part that it is not a […]
