Why does Greece’s electricity market remain so expensive?
Despite the increase in electricity generation from Renewable Energy Sources (RES), Greece consistently remains among the most expensive countries in Europe in the day-ahead electricity market (DAM). According to a new analysis by The Green Tank, which also compares Greece with Portugal, the main reasons are the country’s growing dependence on fossil gas and the lack of energy storage infrastructure.

Landmark decision by RAAEY on Energy Communities
A decision of utmost importance for the integrity of the institution of Energy Communities (ECs), Citizen Energy Communities (CECs) and Renewable Energy Communities (RECs) was announced last week by the Regulatory Authority for Waste, Energy and Water (RAAEY).
From 7.4 TWh to 1.8 TWh: Six Years of Progress in Phasing Out Lignite
It has been six years since the Prime Minister announced Greece’s full exit from lignite from the UN podium. Up until that decision, and during the first eight months of 2019, the country relied on 7.4 TWh of electricity from lignite. At any given hour of the year, at least one lignite unit was in operation, and the power sector emitted a total of 19 million tonnes of CO₂ over that eight-month period.
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.
Social Equity in Protected Areas – The Green Tank Contributes to a Global Study
The Green Tank contributed to a major study assessing the governance of Protected and Conserved Areas (PCAs) worldwide. The study was led by a team from the International Institute for Environment and Development (IIED), with input from the Fidelio program and under the scientific guidance of Dr. Nicoletta Jones (Warwick University / University of Cambridge).
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.
