The EBRD''s involvement in the Enguri hydropower plant''s rehabilitation dates back to 1998.

What is pumped storage hydro?

Pumped storage hydro (PSH) is a large-scale method of storing energy that can be converted into hydroelectric power. The long-duration storage technology has been used for more than half a century to balance demand on Great Britain''s electricity grid and accounts for more than 99% of bulk energy storage capacity worldwide.

Carters Dam

Below the dam is a 1,000-acre (400 ha) retention and re-regulation lake (Reregulation Reservoir). The hydroelectric plant is of the pumped storage type. That is, during off-peak hours the water from the retention lake is pumped back up to Carters Lake for use in generating power during the next time of peak demand.The dam''s power station contains 2 × 140 megawatts (190,000 hp)
