Greek box-type energy storage power station

Does Greece need energy storage?

In its energy transition, Greece relies substantially on energy storage projects. While pioneering auctions for subsidies for battery systems on the European level, the country is also preparing some major pumped storage hydropower projects. The largest one, Amfilochia, is under construction and should be completed by the end of 2025.

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).

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.

How is Greece preparing for energy transition?

The complex is set to consist of two plants with separate upper reservoirs. In its energy transition, Greece relies substantially on energy storage projects. While pioneering auctions for subsidies for battery systems on the European level, the country is also preparing some major pumped storage hydropower projects.

What are the cost assumptions for the Greek power system?

Thermal and hydro unit capacities assumed for the Greek power system. Table B.4. Variable cost assumptions for thermal units and demand response services. Includes fuel costs and CO 2 emissions rights. The investment cost assumptions for BESS, PHS and OCGT investments are presented in the following Table B.5, Table B.7.
