  2. Foundations for the Transformation • The Tropical Institute of Energy, Environment, and Society (ITEAS) UPRM-PV installations on 65% of roofs of residential structures built in Puerto Rico could generate all the energy consumed in Puerto Rico in 2009 when consumption was higher. http://www.uprm.edu/aret/docs/Ch_1_Summary.pdf, p. 1-13 to 1-14. • The siting of solar systems on previously contaminated land. NREL has established that photovoltaic installations in closed landfills is viable in Puerto Rico due to the relative scarcity of land. See http://www.osti.gov/bridge.

  3. Viability-Power Electronics, Renewables, DR, BESS • A Customer-focused Framework for Electric System Resilience, Silverstein, A., Gramlich, R., Goggin, M., Reliability Services Capabilities for Major Energy Sources • Voltage support: Reactive power and voltage control; Voltage and frequency disturbance ridethrough, Frequency support: Frequency stabilization following a disturbance; Power electronics provide very fast and accurate power injection following a disturbance; Ramping and balancing: Frequency regulation, Peak energy, summer. • A Case Study of Residential Electric Service Resiliency thru Renewable Energy Following Hurricane María, Irizarry,A. Montano, K, Alzate, S., Andrade, F.

  4. Economic Viability of Rooftop Solar • The draft Integrated Resource Plan (IRP) prepared by Siemens Industry, Inc for the Puerto Rico Electric Power Authority (PREPA) indicates that the unit costs for all customer alternatives considered are lower than the final all-in (ESM and S4S2) generation portfolio rates.(Pages 8-30 and 8-46 of the IRP). The cost of customer owned generation is significantly lower than the total rate. • In spite of the fact that rooftop solar is shown to be cheaper in the IRP (Exhibit 8-38 ESM Future Installed Capacity Mix) customer owned solar is severely limited to about 10% of the generation mix in 2038. • Credit Union financing for solar kits
