With Greece targeting 3GW of energy storage by 2030 to support its 25GW renewable energy push, understanding Battery Energy Storage System (BESS) quotations has become critical for businesses. But why are prices swinging between €300–€600 per kWh today? And how will government subsidies reshape. . Following a competitive national tender in 2023, over 900 MW of standalone BESS projects were awarded availability contracts under a € 341 million EU-funded scheme. If European costs follow suit, hitting €80 k/MWh (or €80/kWh) by summer 2026 could be within reach. Rapid cost declines BloombergNEF reports the steepest. . The cost of BESS has fallen significantly over the past decade, with more precipitous drops in recent years: This is nearly a 70% reduction in three years, owing to falling battery pack prices (now as low as $60-70/kWh in China), increased deployment, and improved efficiency. However, while the scale of ambition is high, there are several tensions emerging—especially around the move toward unsponsored. . The 1st BESS Tender was conducted for a total capacity of 400 MW for BESS, while the 2nd BESS Tender for approx. 290 MW, to be developed throughout the country with the exception of the island of Crete. The average bidding price (Reference Tariff), in €/MW/year of the 1st BESS Tender was 49,748.
This paper comprehensively evaluates the operational benefits of energy storage configurations under different models, providing quantitative references for the rational selection of energy storage modes in renewable energy projects. . It constructs a new energy storage power station statistical index system centered on five primary indexes: energy efficiency index, reliability index, regulation index, economic index, and environmental protection index; proposes Analytic Hierarchy Process (AHP)–coefficient of variation. . This paper proposes a benefit evaluation method for self-built, leased, and shared energy storage modes in renewable energy power plants.
