Greece’s Ministry of Environment and Energy has put forward a package of regulatory reforms targeting renewable energy self-consumption, following a public consultation held earlier this month.

The proposed directive introduces a landmark provision permitting balcony photovoltaic installations of up to 800 W for the first time. The balcony PV systems will operate purely for on-site self-consumption and are banned from exporting power to the grid, with mandatory safety standards to safeguard grid infrastructure and other electrical equipment. The consultation also reviewed plans to enable standalone residential battery storage, likewise limited exclusively to self-consumption.

Further measures aim to advance collective self-consumption within apartment blocks and residential complexes. The framework will allow third-party developers to build self-consumption assets on consumers’ behalf, and enable participants served by different power retailers to join the same collective self-consumption scheme.

To streamline administration, the ministry intends to speed up the rollout of smart electricity meters for self-consumption users and launch a dedicated electronic registry. The digital platform will simplify paperwork and boost data exchange among market stakeholders.

The amendments seek to address implementation gaps under the existing self-consumption rules by clarifying procedures for scheme deployment and settlement. The reform follows Greece’s Law 5299/2026, enacted in May, which created renewable energy acceleration zones and transposed the EU RED III directive into national law.
