The Belmeken (Bulgarian: Белмекен) dam is situated in the Rila Mountains and is the highest dam lake on the Balkan peninsula. There is a pumped-storage plant built on the lake (PSP) (Bulgarian: ПАВЕЦ). It is part of the cascade Belmeken-Chaira-Sestrimo. Part of the water used in the PSP is returned by its pumps, while the rest is sent through tunnels in the Sestriomo WPP (Water Power Plant). From there it flows again through tunnels to the third and last dam with Chaira PSP[clarification needed]. The construction of a fourth dam, Iadenitsa, is in progress and will be finished in the coming years.

Chaira PSP is the largest in southeast Europe, and first in the world as regards the highest head for a single-stage pump turbine (690 m generating and 701 m pumping).[1]
