The energy regulator in Belgium’s Wallonia region has officially approved fees for households with rooftop solar installations. These households will pay an additional EUR 330 to EUR 560 (CZK 8,580 to CZK 14,560) per year. The Czech Energy Regulatory Office is also considering additional fees for households with solar panels.
Rooftop residential solar PV system operators have now been targeted in Belgium. Following a consultation period, the local regulator announced new fees for residential rooftop installations, with the amount depending on installed capacity and the geographical location of the house.
These fees are relatively high, potentially reaching up to CZK 15,000 per year, which will ultimately affect the return on investment in the purchased system. By the end of last year, installed solar capacity in Belgium had exceeded 3.4 GW, of which 916 MW was located in Wallonia.
The fee will take effect in 2020, with the regulator postponing its introduction by one year, as the original plan was for it to be paid from 2019. According to data from a local association representing small-scale electricity self-producers, approximately 133,000 households will be affected by the fee.

Although households are a driving force behind solar generation in neighbouring Germany, for example, a large number of such self-producers poses a problem for distribution system operators.
Distribution fees are paid as a regulated component of the electricity price, meaning that with lower electricity consumption, self-producers contribute less towards operating the distribution system. Additional fees are therefore often considered to compensate for the costs of operating and developing the distribution system.
Last year, the Energy Regulatory Office presented a new tariff structure, which was ultimately postponed. Under the proposed approach, seasonal consumers would also have paid more in fees, and they understandably opposed the changes.
A new form of tariffs for self-producers is currently being discussed again. According to news website iHned, the changes should primarily affect self-producers, especially households with solar panels on their roofs.
The new tariffs are expected to be presented by the end of this year, with the changes set to take effect from 2019.
