Technical FAQs 4

Should Greece invest in pumped hydropower storage facilities?

The pileup of proposals for wind and solar power plants in Greece bolstered the interest in investments in pumped hydropower storage facilities to balance the output from the two intermittent sources. Government-controlled PPC is dominating the map.

How much power does a pumped Energy Storage Project have?

Out of 1.87 GW in operating power, the five pumped storage project account for 1.21 GW. Their overall guaranteed capacity came in at a 9.6 GWh. A firm called ZSV Wind Force obtained in July an energy storage license for a project of 290 MW, or 270 MW in pumping mode. It would also be located in the Grevena regional unit.

What is pumped storage hydropower?

Pumped storage hydropower is still the only reliable technology for balancing on a massive scale. The point is to bridge the gaps between renewable electricity supply and demand. In theory, helped by demand response and batteries, a strong pumped storage capacity can keep the power system stable for days without wind and with little solar power.

Why is Greece preparing a third battery energy storage tender?

Greece is already preparing its third battery energy storage tender, making it one of the most advanced markets in Europe, but acceleration is also evident in the pumped storage hydropower segment. Wind and solar power plants are being built in such quantities that neither demand nor the grid can keep up.
