Greece charges ahead: Record electricity exports powered by renewables in 2025

Political energy strategy in the spotlight — green leadership meets network strain and gas reliance

In a historic shift for its energy landscape, Greece closed out 2025 with record-breaking clean electricity exports, driven by a surge in renewable energy production, positioning the country as a net exporter of electricity within the region. According to the Green Tank energy analysis, Greece’s net electricity exports exceeded 3 TWh (3,010 GWh) — nearly ten times the 2024 level — highlighting a major milestone in the country’s power sector evolution.

This dramatic turnaround reflects more than just statistical achievement: it underscores Greece’s growing role as a regional energy player, no longer solely dependent on imported power and increasingly integrated into cross‑border grid flows.

Renewable Revolution Meets Political Reality

The share of renewables (wind, solar, hydro) in Greece’s electricity mix climbed to 46.7% of domestic demand in 2025, the highest proportion ever recorded, with renewables leading total generation. This breakthrough aligns with broader EU trends in renewable growth — where wind and solar output surpassed fossil fuels for the first time — illustrating Greece’s position among the continent’s top performers.

Yet this green success story carries a nuanced political and strategic dilemma. While renewable output reached unprecedented heights, the annual growth rate of renewables slowed to just 3.9%, compared with an average annual increase of 15% over the previous six years, suggesting emerging bottlenecks in infrastructure and grid integration.

At the same time, natural gas generation also climbed to a historic high — with gas providing a substantial share of electricity production — underscoring a complex dependency on fossil fuel ‘bridge’ resources even as renewables expand.

 Strategic Crossroads for Greek Energy Policy

Greek policymakers now face a set of parliamentary‑level choices with long-term implications:

• Managing the renewable boom without robust storage: The record share of renewables has also resulted in increased hours of zero or negative wholesale prices, reflecting the grid’s struggle to absorb surplus clean energy without adequate storage and flexibility mechanisms.
• Balancing gas and green energy: While renewables dominate generation, the rising role of natural gas complicates Greece’s path to deep decarbonisation and exposes it to global fuel price volatility — a politically sensitive issue that could shape debates in both government and opposition circles.
• Infrastructure and storage policy: The lack of large‑scale energy storage remains a structural weakness. Although Greece has conducted battery storage auctions, scaling up storage capacity is vital to ensure that the country’s export trajectory is sustainable rather than episodic.

Regional and EU Energy Dynamics

Greece’s record performance is not isolated. Across the European Union, renewable sources supplied nearly half of electricity generation in 2025, with solar alone reaching record levels and wind contributing significantly — positioning Europe on an accelerated decarbonisation track.

However, this broader success contrasts with ongoing debates in Brussels about grid investment, market design reform, and energy sovereignty — all of which reflect back on national strategies like Greece’s.

Political Stakes and Future Outlook

For the Greek government, the 2025 energy figures are both a triumph and a challenge. They provide political capital to claim leadership in the energy transition while also exposing vulnerabilities in infrastructure and policy that opposition parties and civil society will wield as points of critique.

The next political battleground will likely center on energy storage investment, grid modernization, and balancing environmental goals with energy security — issues that will influence everything from electricity prices to foreign investment and Greece’s standing within the EU’s broader energy strategy.
