Table 2 Constants derived for each pumping scenario and discount rate

From: Conditions for economic competitiveness of pumped storage hydroelectric power plants in Egypt

Pumping cost scenario r (%) Regression equation
Scenario 1: pumping cost is equal to the price of buying electricity from the Egyptian Unified Grid at off-peak time 8 \(I = 25650 \;{\text{LCOE}} - 2013\)
10 \(I = 22510 \;{\text{LCOE}} - 1632\)
12 \(I = 20340\;{\text{LCOE}} - 1387\)
14 \(I = 18870\;{\text{LCOE}} - 1246\)
Scenario 2: pumping cost is 70% (fuel portion cost) of the total energy payment cost in first scenario 8 \(I = 25540 \;{\text{LCOE}} - 1537\)
10 \(I = 22540\;{\text{LCOE}} - 1272\)
12 \(I = 20380\;{\text{LCOE}} - 1083\)
14 \(I = 18850\;{\text{LCOE}} - 963.9\)
Scenario 3: pumping cost is assumed to be zero 8 \(I = 25590\;{\text{LCOE}} - 503.3\)
10 \(I = 22450\;{\text{LCOE}} - 407.4\)
12 \(I = 20390\;{\text{LCOE}} - 360\)
14 \(I = 18860\;{\text{LCOE}} - 323\)
