Greece has established itself as a key player in the Southeast European electricity market, with net electricity exports surging to 2,671 GWh in 2025, up from just 307 GWh the previous year. This substantial increase reflects a broader trend of cross-border electricity flows favoring exports, as reported by the national energy regulator.
This remarkable growth indicates that Greece’s export success is not merely a fleeting occurrence but part of a structural evolution within its energy landscape. The country has transitioned into a net exporter of electricity, highlighting its enhanced capacity and competitive positioning in the regional market.
Central to this transformation is Greece’s cost advantage over neighboring countries, driven primarily by an increasing reliance on renewable energy sources. This shift has resulted in lower wholesale electricity prices, enhancing Greece’s competitiveness on the international stage. Total electricity generation rose approximately 7% year-on-year to about 56.6 TWh in 2025, compared to 53.1 TWh in 2024.
Renewable energy sources contributed significantly to this output, accounting for around 47% of total generation. The sector saw an impressive growth of about 8%, reaching approximately 26.9 TWh, with solar power being the primary driver of this expansion due to the addition of an estimated 2.5 GW of new photovoltaic capacity. Meanwhile, domestic consumption remained steady at about 51.4 TWh, allowing the surplus production to be exported.
The increase in exports was further supported by a rise in gas-fired generation, which grew by roughly 8%. This development has played a crucial role in maintaining system stability while bolstering Greece’s position within regional electricity trade dynamics.
