Solar microgrids across Puerto Rico withstand quakes; boost case for distributed generation

Solar microgrids installed throughout Puerto Rico after Hurricane Maria didn’t lose power when massive earthquakes tore through the island’s electric grid earlier this month. The microgrids, many of which are permanently off-grid, were able to continue operating despite serious damage to transmission lines and power plants. Operators see this as an argument for shifting to distributed generation, which is included in the Puerto Rico Electric Power Authority’s (PREPA) integrated resource plan.
