Rural communities in Puerto Rico are banding together to host solar-powered microgrid systems for emergencies like Hurricane Fiona and for day-to-day use. Electricity prices have increased to 33 cents per kWh in 2022—almost double the 2020 rate—due to global increases in the cost of natural gas, which needs to be imported to the island..
A Microgrid is defined as a group of interconnected loads and energy resources within clearly defined electrical boundaries, acting as a single controllable entity that can connect and disconnect from the grid to operate in either grid-connected or islanded mode. Three (3) main types of Microgrids will be recognized under the Regulation:.
Through this Resolution, the Puerto Rico Energy Commission (“Commission”) adopts and publishes the Regulation on Microgrid Development (“Final Microgrid Regulation”)..
