The energy ministry plans to allot 400 million euros of EU recovery fund money to the development of central electrical energy storage units. A related proposal by the ministry is headed for inclusion into the national recovery plan.
The aforementioned sum will be used to subsidize energy storage projects and will be made available to investors through a mechanism whose details are still being negotiated by government and European Commission officials.
Once the mechanism has taken final shape it will be forwarded to Brussels’ Directorate-General for Competition and Directorate-General for Energy for approval from both, necessary ahead of its implementation.
Though further details on the prospective support mechanism remain unknown, its subsidies are expected to be offered through a competitive procedure promoting selected projects.
At this point, developments have indicated both central energy storage technologies – pumped hydroelectric energy storage and accumulators (battery units) – will be eligible for subsidy support.
A study on central energy storage conducted by the National Technical University of Athens (NTUA) for RAE, the Regulatory Authority for Energy, has shown that a combination of these two technologies is the optimal solution, as each covers different needs.
