Self-consumption capacity set to break 1 GW in Greece

Renewable energy projects for self-consumption are expected to reach 1 GW this year in Greece.

According to the Green Tank, at the end of March 2025, self-consumption capacity amounted to 937.6 MW, of which the overwhelming majority (871.9 MW) was in photovoltaics.

It should be noted that last year the government introduced a big change in the segment. The net metering regime was abandoned in favor of net billing, following European guidelines.

Insufficient capacity limit

There were 32,955 self-consumption units in the country at the end of the first quarter. Projects in operation plus remaining applications are estimated at 1,865 MW, which is near the 2 GW ceiling, set by law.

Energy communities, small companies, farmers and individuals have asked for the available capacity to be increased.

They also complain that the Hellenic Distribution Network Operator (HEDNO or DEDDIE) is too slow with connecting them to the grid. The operator has mostly been integrating units in the category of up to 10.8 kW, while ignoring larger projects.

The Renewable Energy Sources Operator and Guarantees of Origin (DAPEEP) began accepting net billing applications for projects of over 10.8 kW only last month. It means it needs to accelerate connections to keep pace.

Renewable energy aggregators have warned that the regulatory framework is unclear when it comes to such projects and their representation in the market.
