Battery-based RES facilities (both standalone units and behind-the-meter projects) will total 3,100 MW, greatly contributing to the country’s energy-storage targets, according to a draft of the revised National Energy and Climate Plan.

The energy-storage support package will result in a portfolio of standalone batteries with an overall capacity of as much as 1,500 to 1,700 MW, deputy energy minister Alexandra Sdoukou told a recent event staged by SEF, the Hellenic Association of Photovoltaic Companies (HELAPCO).

These levels represent an additional capacity of between 500 and 700 MW in standalone batteries eligible for subsidy support as a result of a reduction in investment support to be offered, it has been estimated.

Energy-storage projects representing roughly 700 MW have qualified for subsidy support through two auctions.

As for the portfolio’s allocation, the energy ministry is considering dividing it into two-hour and four-hour batteries, in place of an initial plan that had envisaged 700 MW of two-hour batteries and 300 MW of four-hour batteries.
