Trends in electricity production – June 2025
In June 2025, renewables (RES) ranked first in electricity production with 2,507 GWh, despite significant curtailments (352 GWh – 12% of total monthly RES production). Domestic electricity demand reached 5,094 GWh, +22% compared to May. Nevertheless, the average market price remained low at 85.4 €/MWh. During the first half of the year, lignite covered just 5.2% of domestic demand – the lowest share in a decade. In contrast, gas-fired generation reached a ten-year high (10,925 GWh), while net electricity exports were also high (783 GWh).
“The energy transition needs social justice” – The Green Tank speaks at event on Energy Democracy
The importance of energy democracy and the need for a socially just energy transition were highlighted by Ioanna Souka, Energy Policy Analyst at The Green Tank, during her participation in the online event organized by the citizens’ initiative O Kosmos on July 24, marking the 51st anniversary of the restoration of democracy in Greece.
Green Transition and Social Justice: Greece Faces ETS2
Nikos Mantzaris spoke on Naftemporiki TV about the impacts of the new Emissions Trading System (ETS2) for buildings and road transport on vulnerable households, as well as the tools Greece has at its disposal to address them.
Greece ranks 6th in ETS emission reductions over 2005–2024
Despite notable progress, 2024 saw an increase in emissions from power generation in Greece due to fossil gas and stagnation in industrial emissions. In contrast, the EU-27 achieved a 20-year low in emissions in both sectors. Greece also ranked first among EU-27 countries in shipping emissions, while emissions from aviation doubled compared to 2013.
Greece Introduces Sectoral Carbon Budgets
The Green Tank submitted its comments and proposals during the public consultation on carbon budgets across seven sectors of the economy.
Comments and recommendations by The Green Tank on the Social Climate Plan public consultation
The Green Tank submitted comments on Greece’s national Social Climate Plan, which has been open for public consultation since July 4 and concludes on July 18. This Plan is the main strategy for designing measures and policies aimed at mitigating the socio-economic impacts of implementing the new Emissions Trading System for buildings and road transport (ETS2).
Trends in fossil gas consumption & imports – June 2025
Gas consumption hit a historic high in the first half of 2025, reaching 34.6 TWh, mainly driven by power generation (67%), which recorded a ten-year record high (23.3 TWh). LNG was the top source of imports, surpassing Russian gas. In June, gas consumption rose to 5.5 TWh (+29.4% compared to May). Across Europe, gas consumption increased by 7% over the first five months, with Greece among the 19 countries that saw higher consumption.
The Green Tank calls for a stronger EU ETS to accelerate a just transition to a climate-neutral economy
The Green Tank submitted detailed positions in response to the European Commission’s Call for Evidence on the revision of the EU ETS Directive, along with comprehensive answers to the related questionnaire, actively contributing to the shaping of Europe’s flagship climate policy. It supports strengthening the EU Emissions Trading System (EU ETS) and the Market Stability Reserve (MSR) to accelerate the transition to a climate-neutral economy in a fair and socially equitable manner.
Greece and ETS2: What It Means for Households and How to Protect the Most Vulnerable
Spending by vulnerable households in Greece is expected to increase by up to EUR 1.6 billion between 2027 and 2032 due to the implementation of the new Emissions Trading System (ETS2) for buildings and road transport. A new study by The Green Tank and Facets recommends a mix of immediate and long-term measures, costing up to EUR 15.5 billion, leveraging the Social Climate Fund (SCF) and other available resources to protect vulnerable households while also contributing to climate targets.
The LIFE EFFECT project is co-funded by Greece’s Green Fund
Following the decision of the Green Fund’s Board of Directors under the Ministry of Environment and Energy, which convened on July 2 2025, co-funding was approved for The Green Tank for the LIFE EFFECT project for the year 2025. The LIFE EFFECT project (LIFE Effective and Fair European Carbon Trading: Ensuring EU carbon pricing and…
The carbon footprint of electricity production – May 2025
In May 2025, the carbon intensity of power generation dropped to a 10-year low (214 g CO2/kWh) thanks to the rise of renewables. However, a total of 6.34 million tons were emitted in the first five months of 2025 due to a surge in gas use. With only 3.856 million tons left in the sector’s carbon budget for the year, the country is off track to meet its 2025 NECP target. Notably, had there been no RES curtailments during the first five months (975 GWh), the power sector would have emitted 0.54 million tons less, more than the total emissions
Trends in electricity production – May 2025
975 GWh of RES were rejected cumulatively in the first 5 months of 2025 (383 GWh in May), exceeding the total curtailments for the entire year of 2024 (899 GWh). Despite these high curtailments, RES production in May reached 2,219 GWh. This brought the average price on the energy market down to 81.9 €/MWh - the lowest in the past 12 months. Gas-fired generation ranked second, with a moderate rebound to March levels (1,457 GWh), while the interconnection balance returned to net exports after March, totaling 139.7 GWh.
Greece: New Historic Lows for Lignite in the First Half of the Year
According to data from Entso-E, the hours of zero lignite production in the first half of 2025 increased by almost 12%, reaching 817 hours compared to 732 hours during the same period in 2024. The vast majority of these zero-production hours (809 hours) occurred after the end of the district heating season in Western Macedonia (May 15, 2025).
RES & Energy Storage in Greece: The Green Tank presents data to the Hellenic Parliament
Presenting to the Special Standing Committee on Environmental Protection of the Hellenic Parliament on June 25, 2025, Nikos Mantzaris, policy analyst and co-founder of The Green Tank, highlighted Greece’s remarkable progress in renewable energy (RES) and the urgent need to scale up storage infrastructure.
