hybrid renewable storage cost breakdown in Greece 2026

Should Greece invest in energy storage facilities?

Currently there is a growing interest for investments in storage facilities in Greece. Licensed projects mostly consist of Li-ion battery energy storage systems (BESS), either stand-alone or integrated in PVs, as well as PHS facilities .

How many storage plants are there in Greece?

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).

Why is Greece launching a storage auction in ?

Funding was first announced in as part of the National Recovery and Resilience Plan. Initially a response to the COVID 19 pandemic, the focus has pivoted to support Greece’s green energy transition. The storage auctions themselves require further approval under EU State aid rules.

How long should energy storage be in a Greek power system?

Considering the energy arbitrage and flexibility needs of the Greek power system, a mix of short (~2 MWh/MW) and longer (>6 MWh/MW) duration storages has been identified as optimal. In the short run, storage is primarily needed for balancing services and to a smaller degree for limited energy arbitrage.

What changes have been made to electricity storage in ?

In major interventions took place in the legal framework to establish the activity of electricity storage, with law / introducing the following: Typology of storage -FtM facilities and BtM storage in RES plants and prosumers. Streamlining of licensing procedure. Participation in all electricity markets.
