In 2025, Greece’s electricity market underwent a notable transformation, with net electricity exports reaching 2,671 GWh, a substantial increase from 307 GWh in 2024. This shift highlights Greece’s emergence as a key player in regional energy supply, as confirmed by data from the national energy regulator.
The rise in exports is not an isolated incident but rather part of a sustained trend that began in 2024. Greece has established itself as a net electricity exporter, reflecting a structural change within its electricity system that enhances its role in the broader Southeast European energy landscape.
A critical factor contributing to this development is Greece’s growing cost advantage relative to neighboring countries. The country’s increasing reliance on renewable energy sources has driven down wholesale electricity prices, making Greek power more appealing to foreign markets. Overall electricity generation surged by approximately 7% year-on-year, totaling around 56.6 TWh in 2025, up from 53.1 TWh the previous year.
Renewable energy sources accounted for nearly 47% of total electricity output, with generation from renewables rising about 8% to reach 26.9 TWh. Solar power emerged as the leading contributor to this expansion, bolstered by an addition of approximately 2.5 GW of new photovoltaic capacity. Meanwhile, domestic electricity consumption remained relatively stable at around 51.4 TWh, allowing for increased availability of surplus production for export.
The uptick in exports was also supported by an increase in gas-fired generation, which grew by roughly 8%. This development has played a crucial role in maintaining system stability while facilitating Greece’s expanding participation in regional electricity trade.
