The first utility-scale batteries will become operational in 2026, and curtailments are expected to ease. The National Energy and Climate Plan (NECP), however, foresees only 3.1 GW of BESS until 2030. This is not enough to keep curtailments at reasonable levels. We would need anything from 5 to 8.
The European Commission has approved a €1 billion (US$1.1 billion) state aid measure for Greece to support two solar-plus-storage projects. Consisting of two solar PV projects co-located with storage, the first one is the Faethon Project, comprising two solar plants of 252MW of capacity each and.
The pileup of proposals for wind and solar power plants in Greece bolstered the interest in investments in pumped hydropower storage facilities to balance the output from the two intermittent sources. Government-controlled PPC is dominating the map. Greece is already preparing its third battery.
From 2018 to 2022, solar capacity in the Mediterranean country grew from 2.6 to 5.3 gigawatts, whereas wind installations increased from 2.8 to 4.7 megawatts. Investments in solar and wind technologies have also followed a similar trend, with total clean energy investments surpassing 1.8 billion.
In this strategic hybrid energy project, a 200MW photovoltaic system is planned to be installed and will be developed and developed together with a lithium-ion battery energy storage system with an installed capacity of 100MW and a 50MW hydrogen electrolyzer capable of producing 16 tons of hydrogen.
Currently there are four (4) storage plants operating in Greece, two open-loop pumped-hydro storage (PHS) stations in the mainland (700 ΜW in total) and two small hybrid RES-storage stations in non-interconnected islands (just 3 MW). The updated target for a renewable energy source (RES) share of.
