The sector benefitted from generous incentive schemes initially, while it attracted the lion’s share of Recovery and Resilience Facility(RRF) funding in the post-Covid years (Kathimerini 2025a). Some areas have had remarkable success in attracting investment, with solar power reaching 9.7 Gigawatt-peak (GWp) of installed capacity by the end of 2024, already exceeding the NECP projection of 8.5 GWp for 2025 (HELAPCO 2025). Wind power installations, by contrast have slowed, reaching 5.5 GW in the first half of 2025 (ELTAEN 2025), compared to the NECP projection of 7 GW for 2030, while there has been no progress towards meeting new targets offshore wind, which were one of the innovations of the 2023 NECP. Renewables made a record contribution to the electricity mix in the first ten months of 2025, making up 47.7% of the total and overtaking fossil fuels for the third consecutive year as the main source of electricity. There are, however, signs of a slowdown in the sector. The past year also saw record curtailments from the grid, when renewable power was rejected in the hours of peak production due to low corresponding demand. Around 7.5% of renewable generation was rejected, more than double the previous year(Green Tank 2025a). This constraint on the contribution of renewables is largely the result of lack of progress on incorporating energy storage. Of the 4.3 GW of standalone batteries targeted in the revised NECP, only around 300 MW have been installed and none have been connected to the grid(PV Magazine 2026), with government schemes plagued by bureaucratic delays. Curtailments not only limit the present contribution of renewables but also dampen the appetite for future investment and financing for the sector by reducing its profitability. Gas on the ascendant At the same time as renewables show signs of hitting a buffer, natural gas had a record year in 2025, covering 39.9 pct of demand in the power sector, which is the fuel’s greatest consumer in the Greek market. Gas has rapidly regained its share of the electricity mix following drastic cuts in compliance with EU obligations in 2022-2023, which had seen consumption slashed by almost a third(Green Tank 2023). As a result, in spite of being close to achieving full“de­lignitisation”, Greece looks set to miss its 2025 emissions reduction goal for the power sector by a wide margin, producing an estimated 15 million tonnes of CO2 versus the target of 10.2 million tonnes(Green Tank 2025b). This is significant because the sector was expected to deliver around two thirds of all emissions reductions over the decade to 2030. Behind the rebound of natural gas lies a policy hedge that has always been present in the NECP, which describes gas as a“transition fuel” on the path to a fully decarbonised system. Accordingly, the national policy framework lacks a Is the Greek green transition running out of power? 3
