Greece's Wind Power Capacity Surpasses 5.5 GW in H1 2025, Driven by New Grid Connections
Key Insights
Greece's total wind power capacity reached 5,507 megawatts by the end of June 2025, surpassing the 5.5 gigawatt mark.
The first half of 2025 saw 37 new wind turbines, totaling 152.2 MW and representing €180 million in investments, connected to the national grid.
The Hellenic Wind Energy Association (ELETAEN) reported a doubling of the annual growth rate, though it emphasized that this pace is still insufficient for a balanced renewable energy mix.
Athens, Greece – Greece’s total wind power capacity surpassed the 5.5 gigawatt (GW) threshold in the first half of 2025, reaching 5,507 megawatts (MW) by the end of June. This significant expansion was driven by the grid connection of 37 new wind turbines, adding 152.2 MW of capacity and representing investments totaling approximately 180 million euros, according to figures released by the Hellenic Wind Energy Association (ELETAEN).
The achievement underscores Greece's ongoing commitment to bolster its renewable energy portfolio. The 152.2 MW added in the first six months of the year marks a notable acceleration in deployment compared to the same period last year, with ELETAEN reporting a doubling of the annual growth rate. Despite this positive trajectory, the association emphasized that the current pace, while encouraging, is not yet sufficient to achieve a balanced and optimal renewable energy mix within the national grid.
Greece has set ambitious targets for renewable energy penetration, aiming for renewables to cover a significant portion of its electricity demand by 2030. Wind power, alongside solar photovoltaics, forms the cornerstone of this strategy. The consistent addition of new capacity is vital for the country to reduce its reliance on fossil fuels, enhance energy security, and meet its climate change mitigation commitments under the European Green Deal.
The investments in new wind projects reflect growing confidence among developers and financiers in Greece's renewable energy market. These projects often involve complex permitting processes and significant capital expenditure, highlighting the long-term commitment of stakeholders. The successful integration of these new assets into the national grid also points to ongoing efforts by grid operators to enhance infrastructure and manage the increasing variability associated with renewable energy sources.
While the 5.5 GW milestone is a positive indicator, ELETAEN's assessment highlights the persistent challenge of ensuring a diversified and stable energy supply. The emphasis on a 'balanced mix' suggests a need for accelerated development across various renewable technologies, including energy storage solutions and potentially firm and dispatchable renewables, to complement intermittent wind and solar generation. The industry anticipates continued policy support and streamlined regulatory frameworks will be essential to maintain and further accelerate this growth trajectory in the coming years.
