DESCRIPTION
Modification of the Engineering Design of Civil Works for the Hydro-Pumped Storage layout
TECHNICAL CHARACTERISTICS
The Hydro-Pumped Storage Layout includes:
- Semi-οutdoor Power station, with two (2) variable speed Reversible Units and capacity of:
- 2 x 10,80 = 20,60 MW for turbine mode and
- 2 x 10,50 = 21 MW for pumping mode
- Q = 21,6 m3/s for production mode
- Q = 21 m3/s for pumping mode
- Lower Reservoir is the existing reservoir of Potamoi Dam
- Upper Reservoir is proposed to be constructed uphill, at the top of the right abutment of Potamoi Dam reservoir, indicative capacity of 1,2 x 106 m3
- H = 423 m
- Hard fill embankments A1 = 26.100 m3 and A2 = 36.800 m3
- Vertical Inlet Structure of circular cross section steel pipe DN2500 and length L = 19 m
- Inlet Penstock Tunnel with steel pipe DN2500 and length L = 250 m
- Downstream of the Inlet Penstock Tunnel the connection to the Power Station is proposed with a Penstock DN2500, length L = 1.700 m, placed in a trapezoidal trench, a Penstock Shaft with length L = 70 m and a Penstock Tunnel with steel pipe DN2500 and length L = 230 m
