Puerto Rico - Building Energy Code with Mandatory Solar Water Heating

In 2009, the Governor of Puerto Rico provided assurance that Puerto Rico would update its building energy codes as part of the state's application for State Energy Program funds from the American Recovery and Reinvestment Act (ARRA). Specifically, the Governor's Assurance assigned the Puerto Rican Energy Affairs Administration (EAA) the following responsibilities:

  • Implement building energy codes for residential buildings that meet or exceed the International Energy Conservation Code (IECC 2009).
  • Implement building energy codes for commercial buildings that meet the 2007 ANSI/ASHRAE/IESNA Standard 90.1, “Energy Standard for Buildings except Low-Rise Residential Buildings”
  • Implement a plan to achieve compliance with the

Puerto Rico - Green Energy Fund

Renewable and Efficient Energy Legislation

In July 2010, Puerto Rico enacted two important laws aimed at accelerating Puerto Rico's adaptation of renewable energy and to reduce the island's reliance on fossil fuels. This is especially significant since 70% of the island's electricity comes from oil, according to the government of Puerto Rico. Act 83 created the Green Energy Fund (GEF), which was (for the first time) a dedicated fund held separately from general funds to support renewable energy development in Puerto Rico. The GEF is unlike other public benefits funds in the United States since it is funded by excise (sales) taxes

Puerto Rico - Green Energy Fund Tier I Incentive Program

With funding from Puerto Rico's Green Energy Fund, Tier I rebates are available for photovoltaic (PV) and wind systems up to and including 100 kW in capacity on a first-come, first-served basis.  Projects are eligible for a rebate up to 40% of installed costs, as long as the calculated dollar per watt installed cost is less than the Reference Cost. If project costs exceed the Reference Cost, the incentive will be calculated by using the Reference Cost. Note, higher Reference Costs are allowed in the Special Vieques-Culebra Economic Development Zone. The standard Reference Costs are:

  • Photovoltaic (PV) less than or equal

Puerto Rico - Interconnection Standards

In 2007, the Autoridad de Energía Electrica de Puerto Rico (PREPA*) adopted interconnection standards based on the standard contained in the federal Energy Policy Act of 2005. PREPA promulgated interconnection rules in August 2008 that apply to all distributed generation (DG) projects that interconnect to PREPA’s electric distribution system. Interconnected systems must meet all safety and performance standards established by IEEE Standard 1547 as well as local construction and safety codes. A manual external disconnect switch is required for all interconnected systems.

Customer-generators seeking to interconnect first submit a standardized "Evaluation Request" to PREPA to determine whether or

Puerto Rico - Net Metering

Puerto Rico enacted net-metering legislation in August 2007, allowing customers of Puerto Rico Electric Power Authority, now LUMA, to use electricity generated by solar, wind or "other" renewable-energy resources to offset their electricity usage.

The Puerto Rico Energy Public Policy Act of 2019 guaranteed availability of net metering for 5 years, and calls for a review of the program to be conducted by 2024.

Eligibility and Availability

This law applies to residential systems with a generating capacity of up to 25 kilowatts (kW) and non-residential systems up to one megawatt (MW) in capacity. Senate Bill 2472 of 2012 increased the
