‘Interesting fundamental drivers for energy storage’ in Greece

Greece’s electricity market holds the potential to become an important European market for energy storage technologies like lithium-ion batteries in the coming months and years.

According to Corentin Baschet, head of market analysis at energy storage consultancy group Clean Horizon, a number of “interesting fundamental drivers” exist in the southern European country which are converging. Already 9GW of energy storage applications — including batteries and pumped hydro — have been received since 2019 by the Greek market regulator RAE and 4GW of projects have already received licenses, Baschet told Energy-Storage.news.

Natural gas is the biggest source of power generation on Greece’s grid. A glance at figures for yesterday’s generation (30 August) by fuel on the website of Greece’s Independent Power Transmission Operator (IPTO) for example, shows about a 52% share for gas. Renewables including hydropower were about 19% but a significant portion of Greece’s power still comes from lignite, the most polluting form of coal. About 9% of generation by fuel was lignite.
