Greece has seen a remarkable increase in renewable energy generation in 2024, with green energy accounting for more than half of the country’s electricity consumption during the first ten months of the year, according to estimates from The Green Tank think tank based on data from the Greek electricity transmission system operator, ADMIE.

Between January and October 2024, renewable energy production, which includes electricity from renewable energy sources (RES) and large-scale hydro, rose by 17.1%, reaching 24,438 GWh—the highest level in the past decade. This increase represents a significant jump from the 20,874 GWh produced during the same period in 2023.

The surge in renewable generation enabled green energy to surpass fossil fuel-based electricity by 1,681 GWh. At the same time, fossil fuel-based electricity production increased by 12.5% compared to 2023. Among fossil fuels, natural gas continued to dominate, covering 35.4% of Greece’s total energy demand, followed by diesel at 6.2% and lignite at 5%.

Renewables contributed 51.8% to Greece’s overall electricity generation mix, providing 51% of domestic energy demand in the first ten months of the year. In comparison, net electricity imports accounted for just 1.6% of total demand—its lowest level in a decade.

However, despite this positive trend, Greece’s renewable energy sector faced some challenges in 2024. According to The Green Tank, renewable energy curtailments (instances where electricity production from renewables was limited due to grid constraints) accounted for 3.7% of total output in the January-October period.

This highlights the need for continued investment in grid infrastructure and storage solutions to fully capitalize on Greece’s renewable energy potential, ensuring that the country can make the most of its green energy resources and reduce reliance on fossil fuels.
