The first electric light in Puerto Rico was illuminated in 1893
The history of electricity in Puerto Rico began in March 1893 when the island's first electric light was illuminated. This occurred in the town of Villalba, in the central region of the island, at the home of a wealthy coffee estate owner, José Ramón Figueroa y Rivera. He installed a generator in his home, marking the beginning of electricity in Puerto Rico. This event was documented by Luis Muñoz Rivera in the newspaper "La Democracia" the following month.
Prior to this, in 1890, the Spanish government had invited proposals for establishing an electric energy service for Puerto Rico. However, no plans were finalised until news emerged that San Juan would be a stop on a trip by the queen's daughter, María Eulalia, and her husband, Antonio María de Orleans, en route to the Chicago World's Fair. This prompted the Sociedad Anónima de Luz Eléctrica (SALE), led by Melquiades Cueto, to expedite the installation of the first electric lighting system in San Juan, which they accomplished in May 1893.
During the last decade of Spanish rule, before the US invasion in 1898, key municipalities such as San Juan, Ponce, Mayagüez, and Utuado installed electrical systems. The expansion of electrical service in Puerto Rico was initially driven by private companies, catering to the needs of the thriving coffee and sugar industries. The sugar industry, in particular, experienced accelerated growth after 1900, leading to the construction of new sugar mills and the creation of various electrical systems to support them.
The Puerto Rico Public Irrigation Act of 1908 established the South Coast Irrigation Service, which constructed reservoirs to improve agricultural irrigation. While small private power grids had existed since 1893, primarily for lighting projects, this Act marked the beginning of government involvement in electricity generation. The government constructed facilities to transmit, distribute, and sell energy derived from the reservoirs. The South Coast Irrigation Service became the first government agency to generate electricity for the public, harnessing the energy potential of the water retained behind the dams.
In 1926, the government established the Office of Water Resources Use to administer and operate irrigation systems, public electricity generation, and electric facilities. This office, led by engineer Antonio S. Lucchetti Otero, accelerated the construction of electric facilities with funds from the Puerto Rico Reconstruction Administration (PRRA). The PRRA was created in 1935 to address unemployment and develop an economic reconstruction program, with a portion of its budget allocated to electrifying the island.
Over time, the expansion of electrical service in Puerto Rico led to the creation of the government agency, the Fluvial Sources Authority, in 1940, which later became the Puerto Rico Electric Power Authority (PREPA). PREPA has faced numerous challenges, including natural disasters such as hurricanes and earthquakes, which have caused widespread power outages and infrastructure damage.

The Puerto Rico Electric Power Authority (PREPA) is the island's publicly owned power utility
The Puerto Rico Electric Power Authority (PREPA), also known as Autoridad de Energía Eléctrica (AEE) in Spanish, is the island's publicly owned power utility. PREPA was originally named the Puerto Rico Water Resources Authority (PRWRA), which was created by Act 83 on May 2, 1941, during the governorship of Rexford G. Tugwell.
The history of electricity in Puerto Rico began much earlier, in March 1893, when the wealthy owner of a coffee estate, José Ramón Figueroa y Rivera, installed a generator in his home in the town of Villalba, illuminating the first electric light on the island. In the same year, the Sociedad Anónima de Luz Eléctrica (SALE), led by Melquiades Cueto, installed the first electric lighting system in San Juan. During the last decade of Spanish rule, key municipalities such as San Juan, Ponce, Mayagüez, and Utuado installed electrical systems.
PRWRA unified diverse regional and local electric power companies into one unified electric grid. In 1979, under Law 71, PRWRA changed its name to the Puerto Rico Electric Power Authority (PREPA) since hydropower was no longer the primary source of energy in Puerto Rico. PREPA's responsibilities grew over the years to encompass island electrification.
Throughout its history, PREPA has suffered several outages that have left regions or the entire island without power. For example, in September 2017, Hurricane Maria destroyed PREPA's distribution network, causing a blackout across the island. PREPA has also faced financial difficulties, declaring bankruptcy in 2017 and accumulating over $9 billion in debt. In 2021, as part of a privatization process, Luma Energy took over Puerto Rico's power transmission and distribution system.

PREPA has suffered several outages, leaving parts of the island without power
The history of electricity in Puerto Rico began in March 1893 when the wealthy owner of a coffee estate, José Ramón Figueroa y Rivera, installed a generator in his Villalba home. This generator illuminated the first electric light in Puerto Rico.
Today, the Puerto Rico Electric Power Authority (PREPA) is responsible for electricity generation, power distribution, and transmission on the island. PREPA has suffered several outages over the years, leaving parts of the island without power. In August 2012, for instance, Tropical Storm Isaac left 14,000 residents without electricity. On September 20, 2016, a fire at the Central Aguirre PREPA facility caused a three-day blackout across the entire island.
Puerto Rico's location in the Caribbean makes it susceptible to hurricanes, which have frequently caused widespread power outages. In September 2017, Hurricane Irma left 1 million residents without power. Just days later, Hurricane Maria struck, causing a blackout across the entire island. The hurricanes devastated Puerto Rico's electricity infrastructure, and it took months to restore power to all residents.
In 2019, the Costa Sur Power Plant in Guayanilla was knocked out by an earthquake, leaving 327,000 customers without electricity and water. In April 2022, another island-wide power outage occurred, with over 780,000 customers losing power. PREPA and Luma Energy, which took over Puerto Rico's power transmission and distribution system in 2021, worked together to restore electricity.

Hurricanes in 2017 caused the island's transmission and distribution system to collapse
The history of electricity in Puerto Rico dates back to 1893 when the first electric light was illuminated in the town of Villalba. Wealthy landowner José Ramón Figueroa y Rivera installed a generator in his home, marking the beginning of electricity service on the island. In the following years, key municipalities such as San Juan, Ponce, Mayagüez, and Utuado installed electrical systems, and the government played a role in expanding access to electricity across Puerto Rico.
However, in 2017, Puerto Rico faced a significant setback when Hurricanes Irma and Maria caused widespread devastation to the island's transmission and distribution system. The impact of these hurricanes led to one of the longest blackouts in U.S. history, leaving residents in some parts of Puerto Rico without electricity for almost a year. The hurricanes highlighted the underlying instability of the grid and the challenges faced by the Puerto Rico Electric Power Authority (PREPA) in managing the recovery efforts.
Hurricanes Irma and Maria made landfall in September 2017, bringing strong winds and causing extensive damage to the electricity infrastructure. The storms left approximately 1 million residents without power, and the full restoration of electricity took several months. The hurricanes exacerbated existing issues and severely disrupted critical sectors, including communications, water and wastewater management, transportation, healthcare, and manufacturing.
The impact of the hurricanes on Puerto Rico's transmission and distribution system was far-reaching. The destruction of the grid led to a prolonged blackout, affecting residents, businesses, and essential services. The Federal Emergency Management Agency (FEMA) provided significant financial support, totaling about $3.2 billion for electricity restoration efforts as of July 2018. However, the recovery process was challenging due to the scale of the damage and the pre-existing financial constraints faced by PREPA.
In the aftermath of the hurricanes, PREPA faced accusations of hoarding spare parts needed for power restoration. The slow progress in restoring electricity supply to all residents triggered protests, and the initial $300 million contract for power restoration was mired in controversy due to the small size of the contracted company. The hurricanes exposed the vulnerabilities of Puerto Rico's electricity grid and highlighted the need for improved grid resilience and modernization.
The hurricanes of 2017 served as a catalyst for change in Puerto Rico's energy sector. In 2019, the Puerto Rico legislature passed the Puerto Rico Energy Public Policy Act (Act 17), setting ambitious targets for renewable energy adoption. The U.S. Department of Energy (DOE) has also played a pivotal role in supporting Puerto Rico's energy recovery, providing tools, training, and modeling to enhance the resilience of the electric system. These efforts underscore the ongoing commitment to rebuilding and modernizing Puerto Rico's energy infrastructure.

The history of electricity in Puerto Rico began in 1893, when the wealthy owner of a coffee estate, José Ramón Figueroa y Rivera, installed a generator in his home in the town of Villalba, illuminating the first electric light in Puerto Rico. In the same year, the Sociedad Anónima de Luz Eléctrica (SALE), led by Melquiades Cueto, installed the first electric lighting system in San Juan.
In the years that followed, Puerto Rico's economy experienced significant growth, with its coffee industry conquering European markets and high prices. This economic windfall resulted in the installation of electrical systems in mountain towns and key municipalities, including San Juan, Ponce, Mayagüez, and Utuado.
Over time, the expansion of electrical service in Puerto Rico transitioned from private companies to government agencies. In 1940, the Fluvial Sources Authority, later renamed the Puerto Rico Electric Power Authority (PREPA), was established to manage the country's electrical power.
However, PREPA has faced numerous challenges, including financial constraints, natural disasters, and infrastructure issues. In 2017, Hurricanes Irma and Maria caused widespread destruction to Puerto Rico's transmission and distribution system, resulting in one of the longest blackouts in U.S. history. These hurricanes, along with subsequent earthquakes, severely damaged the country's power plants and electrical infrastructure.
Recognizing the urgent need for improvement and resilience in Puerto Rico's electric system, the U.S. Department of Energy (DOE) has provided significant support:
- The DOE has leveraged its network of National Laboratories to provide advanced planning and modeling capabilities to stakeholders in Puerto Rico. This includes tools, training, and modeling support to enhance the resilience of the electric system against further disruptions.
- They serve as an unbiased convener and coordinator among relevant federal and local decision-makers, ensuring that funded recovery actions adhere to industry best practices and are coordinated across sectors.
- The DOE provides technical assistance to various organizations, including the Central Office for Recovery, Reconstruction, and Resilience (COR3), PREPA, and LUMA Energy. They help develop project applications for FEMA's Hazard Mitigation Grant Program and have designed a renewable microgrid for the island municipalities of Vieques and Culebra.
- In December 2022, Congress approved $1 billion in funding to improve the resilience of Puerto Rico's electric grid, demonstrating a strong commitment to strengthening the country's energy infrastructure.
- The DOE is also involved in the Puerto Rico Grid Resilience and Transition to 100% Renewable Energy Study (PR100 Study). This comprehensive analysis aims to guide Puerto Rico in achieving its goal of meeting 100% of its electricity needs with renewable energy sources by 2050.
- The Biden administration initially awarded $365 million in funding in December 2024 to support rooftop solar and battery storage installations. However, the DOE reprioritized these funds to support technologies that improve system flexibility, response, power flow control, component strength, supply security, and safety.
