Ruta Energética
para Puerto Rico
Puerto Rico’s energy system is undergoing a comprehensive transition to provide more reliable, resilient, and cleaner electricity to the people and businesses of Puerto Rico. The U.S. government is supporting the reconstruction and modernization of the power grid and sources of generation. This website provides information about progress of the energy transition and investment of federal funds.

Puerto Rico’s Energy System Status
The illustration below compares electricity demand on the day with the highest demand each month and available peak generation capacity on that day. LUMA Energy’s BPS Monitoring provides daily and monthly reports on system status. Real-time data and visualizations are available on the System Overview page. Puerto Rico has barely sufficient generating capacity to meet electricity demand.
Most recent
Prior 12-Month Overview
Thought the maximum output (nameplate capacity) of Puerto Rico’s current fleet of power plants and other generation is higher than peak electricity demand, on average only about 46% of PREPA’s legacy generation assets’ nameplate capacity is available. The historical lack of maintenance and poor reliability lead to significant unplanned maintenance downtime.
The illustration below shows the system capacity on the day with the highest peak demand during the most recent month. It shows the system capacity available (green) that day, the limitations (orange), planned outages (light blue), maintenance outages (grey), forced outages (red), and capacity out of service (dark blue) based on data from LUMA Energy. Available supply does not include solar, wind, or landfill gas generation.
See the Generation section of this website for more information about the current and future system.
Footnotes
Peak Demand is the anticipated highest demand at a certain point of the day.
Available Supply means the available electricity that will be generated by the generators. The Available Supply shown in the System Availability Graphs do not include Solar, Wind, or Landfill.
Limitations represent the reduction of electricity that can be generated by the generators. These Limitations are established by each generator.
Outages represent the reduction of electricity that can be generated by the generators due to the unavailability of a unit, or various units. These outages can be scheduled or unscheduled.
Out-of-Service represents units that have been unavailable for a period of 12 months or longer.
