Reversal of the upward trend in emissions in September, with 1.06 million tonnes (-22.7% compared to August), mainly driven by reduced fossil gas consumption. Cumulative emissions since the beginning of 2026 reached 10.66 million tonnes, exceeding the carbon budget set by the National Energy and Climate Plan (NECP) for the entire year by 1.7 million tonnes (+19%). Two lignite-fired power plants (Agios Dimitrios & Ptolemaida 5) topped the list of largest emitters over the first nine months of 2026.

In the first 9 months of 2026, the gap between electricity generation from clean energy sources and fossil fuels widened further, reaching 8.8 TWh. However, September saw the highest monthly average electricity price since January 2023, at €156.3/MWh, driven by a rise in TTF prices to their highest level in the past 3.5 years. Batteries prevented 19.3% of September’s renewable energy curtailments, which totalled 158.2 GWh for the month. Nevertheless, cumulative curtailments since the beginning of the year surpassed the 2 TWh threshold, reaching 2,063 GWh.
