D. Long Results Look Good
Spot checked individual projects◦Project capacity values reasonable◦Consistent with other analyses
Provides insightsHighlights key issues

Observation OneBig difference between
instantaneous peak and sustained peak estimates
14 Federal Projects (Jan. 1937)
◦Instantaneous Peak (NRF)20,508 MW
◦1-hr Sustained Peak (D. Long)12,204 MW

Observation TwoD. Long’s one-hour &18-hour
sustained peak capacity nearly identical
14 Federal Projects (Jan. 1937)
◦1-hr Sustained Peak 12,204 MW
◦18-hr Sustained Peak 12,437 MW

Observation ThreeAmount of energy GREATLY
effects sustained peak capability
14 Federal Projects (Jan. 1937)(Monthly Energy -- 1-hr Sustained Peak)
◦7,200 MWa -- 16,568 MW Whitebook
◦5,600 MWa -- 13,693 MW NRF◦ ???MWa -- 12,204 MW D. Long

Observation FourTreatment of Hydro Maintenance
and Reserves is important
