Slovenia’s Constitutional Court has upheld the revised power grid charging system, rejecting objections to a methodology that links charges more closely to when consumers use electricity and how much network capacity they need. The unanimous ruling keeps in place the methodology introduced by the Energy Agency in October 2024. Tariffs vary by season and time of day, while consumers are assigned agreed billing-capacity levels.
Consumers can face additional charges if their use exceeds the agreed capacity. The National Council challenged the system in 2025 amid controversy over its effects on households and companies. One of the disputes concerned whether these excess-capacity charges amounted to financial penalties.
Court upholds excess-capacity charges
The court accepted the Energy Agency’s position that the charges reflect the additional burden placed on the electricity network. It therefore classified them as tariffs rather than sanctions. The judges also rejected arguments that the charges had been calculated arbitrarily.
The reform is intended to encourage consumers to shift demand away from peak periods and make better use of existing infrastructure, potentially reducing the need for costly network reinforcement. The court reaffirmed the Energy Agency’s authority to set network charges under domestic and European regulatory frameworks. The ruling resolves the constitutional challenge, while consumers and businesses still face the practical task of adjusting their consumption to the new tariff structure.
