Investment interest for the installation of energy storage units is already considerable, even though related licensing and support mechanism frameworks have yet to be established, data presented yesterday by RAE, the Regulatory Authority for Energy, has shown.

According to the data, RAE, since October, 2019, has received 123 applications for prospective energy storage and pumped storage projects representing a total of 12,229 MW.

Of these applications, 110 concern energy storage systems representing a total capacity of 9,102 MW, the RAE data showed.

To date, RAE has already issued production licenses for 38 energy storage units with a total capacity of 3,582 MW.

A further 12 applications representing 2,447 MW are for pumped storage units, not including a Terna Energy project in Amfilohia, northwestern Greece.

So far, RAE has issued three licenses for pumped storage facilities representing 807 MW.

Energy ministry officials already suspect the energy storage market may experience overheating issues, as has been the case with the RES market.
