Greece is on track to achieve 1 GW of renewable energy capacity for self-consumption in 2025, with figures from the Green Tank showing 937.6 MW installed by the end of March. The majority of this capacity—871.9 MW—comes from solar photovoltaic systems. This growth follows a major policy shift in 2024, when the government replaced the net metering system with net billing to align with EU directives.
By the end of the first quarter, Greece had 32,955 prosumer units in operation. The combined total of active systems and pending applications now reaches approximately 1,865 MW, approaching the country’s legally mandated 2 GW cap for self-consumption projects.
However, stakeholders such as energy communities, small businesses, farmers, and individuals are calling for an increase to this limit. They also criticize the distribution network operator DEDDIE for delays in connecting new systems, particularly larger installations. To date, most completed connections involve small-scale systems up to 10.8 kW. Larger projects have seen slower progress, with the renewable energy market operator DAPEEP only recently beginning to process net billing applications for installations above that threshold.
Renewable energy aggregators have also voiced concerns over regulatory gaps, particularly the lack of clarity regarding how self-consumption projects are represented in the energy market. This uncertainty, combined with slow grid integration, underscores the need for clearer rules and faster infrastructure development to support Greece’s growing prosumer movement.
