Title 24 2008 Energy and Capacity Value
Method and results in this slide are preliminary.
DkW of Equivalent Capacity
in Each Hour
Additional DkW of Equivalent Capacity
Achieved During Stage 3
Note these shapes are from 2004 IEPR.
Price Duration Curve
Scaled to All-in Combined Cycle Cost
Uses $72/kW-year Fixed Cost of a CT Assumption (levelized real)
$85/kW-year (levelized nominal) approx. the same value.
Result is approximately $20/kW-yr
High number of operating hours
Similar analyses for other cases / utilities show approximately 700-900 hours operation
Few hours results in a larger residual capacity value
Control Area Load
Residual Capacity – 100 Hours
Residual Capacity – 250 Hours
