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

The Green Tank’s ninth newsletter for the developments of the last six months (January – June 2025) related to the Just Transition of lignite regions in Greece and in Europe has been published.

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.

The European Commission's Just Transition Platform has set up a Working Group on the future of Just Transition in Europe and the financial instruments that can support it. The Working Group has launched a discussion paper with policy proposals for the continuation of Just Transition in the post-2027 programming period.

Green Tank's comments on the 1st revision of the Just Development Transition Programme 2021 - 2027, and recommendations for the better use of resources for the benefit of people in the lignite areas and the achievement of climate neutrality.

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).

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.

A new brief by The Green Tank analyzes the provisions of European legislation regarding capacity remuneration mechanisms (CRMs), outlines the technologies that other European countries are choosing to support via these mechanisms, and examines how these choices have so far affected consumers’ costs.

At the Energy Transition Summit: East Med & Southeast Europe – held on 17 June 2025 in Athens and organised by FT x Kathimerini – Nikos Mantzaris, Senior Policy Analyst and co founder of The Green Tank, joined experts to explore how Greece and the broader region can harness the region’s rich solar and wind potential.

Nikos Mantzaris and Ioanna Souka participated as speakers, on 3 June 2025, at the event “Energy Transition & Electricity,” organized by Clima21 and the Aegean Energy & Environmental Bureau (EPEGA) at ESIEA. The event focused on critical issues for achieving climate goals and developing clean technologies.
