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 | \(I = 18860\;{\text{LCOE}} - 323\) |
