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 .

Why is Greece launching a battery storage auction?

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. The pipeline of prospective battery storage projects now approaches 27GW, with over 500 projects granted a storage license.

Does Greece have a battery storage pipeline?

Greece has emerged as one of the countries with the largest pipeline of battery storage projects, but as yet there has been little activity on the ground. This is changing as the long-awaited storage subsidy auctions have started, with the first projects being awarded support for both investment and operating costs.

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.

Is Res a good investment for the Greek economy?

An additional national economy surplus to generators as a result of the increased exporting activity Comparing the 3 scenarios, the results show that there is a huge financial potential for both end-customers and generators.
