Claims

C1strongest claim

an optimal portfolio includes at least 1.5 GW of new H-class combined cycle capacity beyond planned projects. These additions are needed mainly to replace unreliable legacy thermal units rather than to serve new load. The new combined cycle units eliminate modeled bulk-system load shedding and restore a strong reserve margin, even under stressed load and outage conditions.

C2weakest assumption

The input data from LUMA, PREPA, DOE, and public sources, together with the assumed high forced outage rates of legacy units and the stochastic scenarios for load, renewables, and outages, accurately represent real-world conditions and future uncertainties.

C3one line summary

Puerto Rico requires at least 1.5 GW of new H-class combined cycle capacity beyond planned projects to replace unreliable legacy thermal units, eliminate load shedding, and restore reserve margins.
