In an article for energypress, Ioanna Souka, Energy Policy Analyst at The Green Tank, emphasizes that supporting unnecessary gas plants comes at a cost to consumers. The recent ENTSO-E power adequacy study (ERAA 2025) shows that a large portion of gas plants in Greece (3.6–4.1 GW out of a total 7.9 GW) is expected to face economic viability challenges.
