Siroka Draga Pumped Storage Hydroelectric Power Plant ( PSHPP )

Pumping Mode : 1120 MW

Turbine Mode: 762 MW

Benefits for Bosnia Herzegovina
and Europe

» Quick and Flexible Response to Grid Peak Power
Demand

» Supports Tight Frequency Control

» Reduced Reliance on Transmission Networks to
Supply Peak Power Demand

» Large Capacity Energy Storage

TI Profile (Longitudinal Section) Water Resource Development Engineering and Construction Services

The design comprises two tunnels due to the capacity and size of the Siroka Draga PSHPP.
The T1 tunnel profile view is shown in this drawing
