{"Walloon households with photovoltaic installations","Energy consumers seeking to understand and reduce electricity costs","Developers and tech enthusiasts interested in Christophe Beyls' software projects"}
Single-author site blending in-depth regulatory/tariff analysis (energy) with a portfolio of open-source software projects and mobile development know-how (Android, Java/Kotlin, MooTools, jQuery).
{"key_dates":["31 December 2023: Free installation of a communal/communicating meter (walloon region prime) available until this date","2024: New installations cannot benefit from the old reverse-meter system; dual-flow meters become essential","2024: Prosumer compensation changes (end of existing subsidies for older installations)","2030: The reverse-meter tariff system is scheduled to end"],"value realization":"Immediate value can be realized by upgrading to a dual-flow meter and using the data to optimize autoconsommation; note the 2023 deadline and 2024 regulatory changes mentioned in the article"}
A family with 2 children and 4500 kWh/year consumption installs 6 kWc PV on a 5 kVA inverter. The capacitary tariff estimates 4550 kWh/year, but actual consumption drops to 3000 kWh/year due to efficiency improvements. The example shows how autoconsommation improvements and overdimensioning can lead to higher or lower charges under different tariff schemas, illustrating the potential misalignment of capacitary estimates and real usage.
Detailed analysis of energy pricing systems targeting Walloon PV owners, explaining the prosumer tariff, the difference between capacitary and proportional tariffs, and the benefits of upgrading to a dual-flow smart meter to minimize costs.
