What You'll Learn
The Puerto Rico Electric Power Authority (PREPA)
The Puerto Rico Electric Power Authority, also known as PREPA (Spanish: AEE), is an electric power company owned by the Commonwealth of Puerto Rico. PREPA is responsible for electricity generation, power distribution, and transmission on the island.
PREPA was originally named the Puerto Rico Water Resources Authority (PRWRA) and was founded on May 2, 1941, during the governorship of Rexford G. Tugwell. As PRWRA, the company unified diverse regional and local electric power companies into one unified electric grid. In 2014, PREPA was subject to the Puerto Rico Energy Commission, another government agency whose board of directors was appointed by the governor.
PREPA has been the sole provider of electricity for close to 1.5 million customers, serving them through several power plants. The company has been producing, transmitting, distributing, and selling electricity for almost 70 years. PREPA is one of the largest public utilities in the United States and ranks highly in clients, revenues, sales kWh, and generation kWh.
However, PREPA has faced significant challenges over the years. The company has suffered several outages, leaving regions or the entire island of Puerto Rico without power. In 2017, Hurricane Maria destroyed PREPA's distribution network, causing a blackout across the island. The company has also faced financial difficulties, with a debt totaling over $9 billion as of 2021. In 2018, the former governor of Puerto Rico, Ricardo Rossello, announced the privatization of PREPA, marking a shift from its previous status as a government monopoly.
Despite these challenges, efforts are underway to improve Puerto Rico's energy system. In 2020, PREPA signed a contract with LUMA Energy to manage the electric grid for 15 years. LUMA Energy has been working to strengthen the grid and reduce power interruptions. Additionally, in 2021, the government announced plans for the Puerto Rico Ocean Technology Complex (PROtech), an ocean thermal energy conversion project. These initiatives aim to provide reliable energy and support the economic growth and fiscal stability of Puerto Rico.

LUMA Energy's role in reducing power interruptions, providing reliable electricity and upgrading the power grid
Puerto Rico has been plagued by unreliable electricity and frequent power interruptions for decades. The Puerto Rico Electric Power Authority (PREPA), the government-owned local utility, has long been criticised for neglecting essential repairs and upgrades to its power grid. In 2017, Hurricanes Irma and Maria devastated Puerto Rico's electricity infrastructure, causing extended blackouts and leaving many residents without power for months.
In June 2021, LUMA Energy took over the operation of Puerto Rico's power grid, with a 15-year, $1.5 billion contract. LUMA's role is to manage the distribution and transmission infrastructure, reduce power interruptions, and provide reliable electricity to the island's residents and businesses. However, the company has faced significant challenges and criticism since taking over.
LUMA has cited pre-existing grid damage and weather events, such as hurricanes and tropical storms, as causes of ongoing power interruptions. The company has also blamed a lack of available supply to meet increasing demand. Despite these challenges, LUMA has made progress in improving the grid's resilience. By December 2024, LUMA had installed 23,000 utility poles to strengthen the grid against storms and completed equipment upgrades at all substations. Additionally, in February 2025, LUMA announced plans to add nearly 1 GW of renewable energy and over 700 MW of storage, attracting $4 billion in private investment.
However, Puerto Rico continues to experience power outages, and LUMA has faced strong criticism from residents, local leaders, and celebrities such as Bad Bunny, who have lambasted the company for its inability to stop the power outages. Despite these challenges, LUMA remains committed to fixing the power grid and playing its part in the territory's transition to cleaner energy sources.

PREPA's $9 billion debt
The Puerto Rico Electric Power Authority (PREPA) is an electric power company owned by the Commonwealth of Puerto Rico. PREPA is responsible for electricity generation, power distribution, and power transmission on the island.
PREPA was originally named the Puerto Rico Water Resources Authority (PRWRA), created by Act 83 on May 2, 1941, during the governorship of Rexford G. Tugwell. Over time, the government-owned PRWRA unified diverse regional and local electric power companies into one unified electric grid for Puerto Rico.
In 2017, PREPA's distribution network was destroyed by Hurricane Maria, resulting in a blackout across the entire island. This was not an isolated incident, as PREPA has a history of outages that have left regions or the entire island without power. The company has also faced criticism for neglecting the necessary repairs to its aging power system.
As of 2021, PREPA's debt totals over $9 billion, and negotiations for debt restructuring have been ongoing. The situation is further complicated by the COVID-19 pandemic and a 2020 law that halted service cuts to clients who failed to pay their utility bills, impacting the agency's earnings.
In 2019, PREPA was close to finalizing a deal with a group of bondholders to restructure its debt. However, the process has been protracted, with the Financial Oversight and Management Board expressing concerns about reaching a consensus with various creditors, including unions and retirees. The board has also objected to the suggestion of filing a debt adjustment plan within 60 days, citing the need for more time to negotiate and resolve disputes.
The PREPA deal is part of a broader effort to address Puerto Rico's economic crisis, with the island seeking to restructure approximately $120 billion in debt and pension obligations. The situation has attracted attention from U.S. lawmakers, who have urged the federal oversight board to approve the power utility restructuring promptly.

Hurricanes Irma and Maria's impact on the electrical grid
Puerto Rico's electrical infrastructure has been devastated by hurricanes, most notably Hurricanes Irma and Maria in 2017. Irma caused an estimated $1 billion in damages, and Maria, a Category 4 hurricane, struck the island head-on, decimating its energy grid. The impact of these hurricanes caused most of the transmission and distribution system in Puerto Rico to collapse, resulting in one of the longest blackouts in US history. Many residents were left without power for months, and the full restoration of electricity took a considerable amount of time.
The Puerto Rico Electric Power Authority (PREPA), the government-owned local utility, has faced criticism for neglecting the necessary repairs to its ageing power system. The energy infrastructure in Puerto Rico has been susceptible to hurricanes and other natural disasters, which have repeatedly caused significant damage. The combination of Irma and Maria left the grid in a highly fragile state, where even a single power line or a bird could trigger a blackout.
In the aftermath of the hurricanes, Congress allocated billions of dollars to rebuild Puerto Rico's infrastructure, including funding for the energy system. However, the process of spending this allocated funding has been slow. The Trump administration's inaction and administrative hurdles contributed to delays in utilising the funds. Despite the availability of federal dollars for repairs, Puerto Rico continues to experience power outages and reliability issues.
To address the ongoing challenges, measures have been implemented to strengthen the power grid and improve reliability. LUMA Energy, which took over the role of operating the power grid in 2021, has made investments to enhance the grid's resilience. They have installed utility poles, upgraded equipment at substations, and worked towards reducing power interruptions. Additionally, Genera PR, a subsidiary of New Fortress Energy Inc., was selected in January 2023 to operate and maintain PREPA's ageing electricity-generating assets through a 10-year agreement. Their short-term repair plan aims to reduce electricity generation outages, while their long-term goal is to add reliable and affordable electricity generation resources.

The privatization of PREPA
Puerto Rico has the least reliable energy system of any place in the US. The territory's power system is in a dire state of disrepair, with plants and substations well past their prime. The public utility has also been caught up in corruption scandals, with Congress probing allegations that PREPA officials received bribes to prioritize restoring power to certain businesses and areas after Hurricane Maria.
The Puerto Rico Electric Power Authority (PREPA) is an electric power company owned by the Commonwealth of Puerto Rico and responsible for electricity generation, power distribution, and power transmission on the island. PREPA was originally named the Puerto Rico Water Resources Authority (PRWRA), created by Act 83 on May 2, 1941, during the governorship of Rexford G. Tugwell. Government-owned, PRWRA unified diverse regional and local electric power companies into one unified electric grid.
On January 22, 2018, former governor of Puerto Rico, Ricardo Rossello, announced that all assets of the company would be sold in a general privatization of PREPA. Rossello's administration, which was self-proclaimed as the "most transparent in Puerto Rico's history," has been criticized for a lack of transparency and regulation surrounding the sale of PREPA. The privatization of PREPA has been described as a “sale too private."
There are concerns that the privatization of PREPA will not reduce electrical rates or foster a renaissance of renewables and microgrids throughout the island unless PREPA's governance changes. PREPA has churned through five different CEOs in the past year and has USD 3.4 billion in accounts receivables. The company's governance remains firmly under the thumb of Puerto Rico's governors, with the governor selecting six of PREPA's seven board members.
Despite the privatization of PREPA, the company's power grid continues to experience issues. In December 2024, a blackout left over 1.2 million people without electricity. LUMA Energy, which began operating in Puerto Rico in June 2021, has been working to reduce power interruptions and provide reliable electricity service to the island's residents and businesses. However, the company has warned that Puerto Ricans could have a tough year ahead of them, as they continue to experience power outages due to supply shortages.
