Electric Reliability and Resiliency in Puerto Rico
Power outages have heightened congressional interest in
Puerto Rico’s electric power infrastructure, which was
damaged by hurricanes Irma and Maria in 2017,
earthquakes in 2020, and hurricane Fiona in 2022. Power
outages continue to occur frequently, with multiple partial
and island-wide blackouts in 2025. In response to reliability
and resiliency concerns, the Secretary of Energy issued two
emergency orders on May 16, 2025, pursuant to Section
202(c) of the Federal Power Act. Subsequently, on May 21,
2025, the Department of Energy (DOE) announced a
redirection of $365 million in funding that had been
awarded for distributed energy solar and battery energy
storage to be used “to support technologies that improve
system flexibility and response, power flow and control,
component strength, supply security, and safety.”
Issues of congressional interest may include oversight of
actions by DOE and other federal agencies, the status of
federal funding for energy projects and the performance of
the electric system, among other considerations.

Federal Funding for the Electric System

Congress has provided funding for Puerto Rico’s electric
power infrastructure through a variety of channels since the
2017 hurricanes, although comprehensive and authoritative
data on the status of awards is difficult to collect.
According to the Puerto Rico Electric Power Authority
(PREPA), as of June 2023, the Federal Emergency
Management Agency (FEMA), the Department of Housing
and Urban Development (HUD), and other agencies
“awarded over $15 billion of federal funding in total.”
Available data as of May 2025 reported by Puerto Rico’s
Central Office for Recovery, Reconstruction and Resiliency
(COR3) indicates that federal funding since the 2017
hurricanes includes FEMA Public Assistance
(approximately $13.6 billion obligated, including
approximately $2.5 billion for emergency protective
measures), FEMA Hazard Mitigation Assistance
(approximately $1 billion authorized), HUD Community
Development Block Grant (CDBG)-Disaster Recovery
(DR): Electric Grid (approximately $1.9 billion), other
HUD CDBG-DR funds (approximately $0.4 billion), and
HUD CDBG-Mitigation funds (approximately $0.5 billion)
for the Community Energy and Water Resilience
Installations Program and other energy-related programs.
Other funding includes the Puerto Rico Energy Resilience
Fund ($1.0 billion) administered by the Department of
Energy (DOE). From 2023 to 2025, DOE issued a partial
loan guarantee to Sunnova Energy Corporation (reportedly
canceled in May 2025); a loan guarantee to Clean Flexible
Energy LLC, for Project Marahu; and a loan guarantee to
subsidiaries of Convergent Energy and Power Inc., for
projects that include renewable and battery storage
development in Puerto Rico. Other authorized federal

programs that could provide financial assistance for energy
projects in Puerto Rico include the Environmental
Protection Agency’s Solar for All program and several U.S.
Department of Agriculture Rural Development programs.
Some funding has been allocated to grantees, but the
majority of obligated funds remain undisbursed. For
example, of the more than $10 billion obligated by FEMA
for permanent work under Public Assistance, approximately
$2 billion has been disbursed as of May 2025. Of the $1.9
billion obligated by HUD’s CDBG-DR for the electric grid,
less than 1% had been disbursed as of July 2024.

Overview of Puerto Rico’s Electric
Power System

Puerto Rico’s electric power system is isolated from other
electric grids and is reliant on fossil fuel-fired power plants.
PREPA is a public utility owned by the Commonwealth of
Puerto Rico and is the largest supplier of electricity in
Puerto Rico, with approximately 1.5 million customers.
PREPA’s generators have a combined installed capacity of
nearly 5 gigawatts (GW). Together with independent power
producers, Puerto Rico’s electric power system has a
generation capacity of approximately 6.3 GW; however, the
available capacity is often less than the installed capacity.
As of December 2024, distributed rooftop solar provides an
additional 1.0 GW, for a total system nameplate capacity of
7.3 GW. Puerto Rico’s total generation capacity, including
distributed sources, is provided by a mix of sources fueled
by petroleum (42%), natural gas (33%), coal (7%), and
renewables (19%) (rounded to the nearest percent).
Before the hurricanes in September 2017, annual electricity
generation totaled approximately 21 billion kilowatt-hours
(kWh) (see Figure 1). After a decrease in electricity
generation in 2017 as a result of long-term power outages
from damage caused by the hurricanes, annual electricity
generation increased from 17.5 billion kWh in 2018 to 19.9
billion kWh in 2023 (with a shift in generation source in
2020 due to earthquake damage). Over the same time
period, the amount and share of electricity generation from
utility-scale non-hydroelectric renewables also increased.

Privatization and Energy Diversification
Efforts
Since the 2017 hurricanes, the government of Puerto Rico
has embarked on initiatives to improve the reliability (the
ability of an energy facility or system to avoid power
disruptions) and resiliency (the ability of an energy facility
or system to recover quickly from damage) of the electric
power system and its governance. These initiatives include
taking steps toward privatizing aspects of the electric power
system and diversifying the energy sources used for Puerto
Rico’s electric power generation.

Notes: kWh = kilowatt-hours. Generation data consist of both utility and non-utility sources from electricity and combined heat and power
plants, reported as net generation. Fossil fuels include coal, petroleum, and natural gas. Non-hydroelectric renewables include solar, wind, and
landfill gas.

Since 2014, several Puerto Rico laws have focused on the
electric power sector. Act 57-2014 reformed PREPA’s
governance and oversight. Act 120-2018 aimed to end
PREPA’s monopoly over power generation, transmission,
and distribution, and it provided for unsold assets to be
operated by private companies. Act 258-2018 allowed for
the formation of electric and energy cooperatives. Act 172019 set renewable energy targets, including a goal of
100% of power from renewable sources by 2050 (with
interim goals for 2025 and 2040) and ending the use of coal
for power generation by 2028. The law also prioritized
enabling consumers to generate their own electricity and
send excess energy to other grid users (known as net
metering). Act 1-2025 removed interim goals for renewable
energy and extended the use of coal through 2032.

Other Considerations

Pursuant to these laws, PREPA entered into agreements
with private companies to manage some aspects of the
electric power system. LUMA began operating and
managing the transmission and distribution system on
June 1, 2021. On June 1, 2023, LUMA stated that service
interruption frequency had been reduced by approximately
35% and interruption duration by approximately 25% since
2021. Genera began operating and managing PREPA’s nonhydropower generation assets on July 1, 2023. PREPA
continues to operate its hydroelectric power plants.

Considerations may include how and at what rate federal
funding has been implemented in Puerto Rico—some
procedures rely on fixed-cost estimates, potentially limiting
the number or types of projects implemented, given recent
price inflation. Another consideration is whether actions by
the Trump Administration—such as declaring a national
energy emergency, implementing policies under Executive
Order 14154, “Unleashing American Energy,” or
considering an application for a Presidential Permit for
transmission connection between Puerto Rico and the
Dominican Republic—may introduce changes or
flexibilities in approving and completing projects. In
addition to conducting oversight, Congress could consider
whether to alter permitting requirements or processes for
energy infrastructure projects—in Puerto Rico and
elsewhere. H.R. 2714 (119th Congress) would establish a
task force to identify solutions and coordinate with relevant
groups to address Puerto Rico’s electricity issues.

In 2024, Puerto Rico enacted legislation amending
electricity net metering program requirements and directed
the Puerto Rico Energy Bureau (PREB) to begin a study to
evaluate the impact of net metering and energy distribution
no sooner than 2030. PREB is responsible for regulating,
monitoring, and enforcing Puerto Rico’s energy policy. Net
metering—widely viewed as a policy that favors smallscale solar projects—can be controversial because utilities
may shift the costs of grid services from program
participants to non-net metering customers in an effort to
recover costs associated with providing electricity.

In early 2024, DOE and others determined that Puerto Rico
could transition to 100% renewable energy by 2050, but the
rate at which energy projects in Puerto Rico can be
designed, constructed, and completed depends on a number
of factors. These include approvals from PREB and the
Financial Oversight and Management Board (FOMB),
which was established under the Puerto Rico Oversight,
Management, and Economic Stability Act (PROMESA;
P.L. 114-187) to lead efforts to restructure Puerto Rico’s
public debts (including PREPA). FOMB has a
responsibility in certifying fiscal plans for PREPA, among
other activities. In 2024, FOMB filed a lawsuit challenging
the amended net metering law. Efforts to negotiate a deal to
address PREPA’s debt continue.
