In an article for energypress, Nikos Mantzaris, policy analyst and co-founder of The Green Tank, examines ENTSO-E data and clarifies the factors behind the drop in electricity prices in Greece on November 26, 2025.
Key Points:
- Renewables – not fossil gas – drove prices down.
Wind and solar generation covered most of the demand, drastically reducing the need for gas. - The size of the gas “fleet” was not related to the lower price, as gas units were barely used.
- Greece was a net electricity exporter all day, meaning domestic gas use could have been even lower.
- Energy storage proves to be a critical factor in price formation.
Portugal’s example shows how combining renewables with significant storage effectively keeps prices down. - Higher prices in Germany were due to low renewable output, not the inability of batteries to reduce prices.
- The new Capacity Remuneration Mechanism (CRM) planned in Germany may be technology-neutral, including clean flexibility solutions.
The article demonstrates that the real recipe for stable and competitive electricity prices is stronger support for renewables and energy storage.
