About Puerto Rico Electric Power Authority

Puerto Rico Electric Power Authority (PREPA) is prepared to serve an entire island nation. The government-owned utility is the sole electricity distributor for Puerto Rico, where it serves more than 1.4 million residential and business customers. PREPA owns five primarily fossil-fueled power plants that, with private cogenerators and purchased power, give it nearly 5,840 MW of generating capacity, and it has more than 33,000 miles of transmission and distribution lines. In order to provide cheaper options for power production, the Puerto Rican government has allowed independent power producers to build cogeneration plants on the island to sell power to PREPA.

Geographic Reach

PREPA operates in seven regions. It has 33 customer service, 29 technical services, and 38 local offices across Puerto Rico.


PREPA's long-term challenges include declining energy sales, high oil costs, and high customer rates, among other issues. It is looking at revenue diversification options and is increasing its activities to reduce energy theft as a way to cut costs.

To cut costs PREPA is also exploring fuel diversification strategies. To this end it is engaging independent power producers, including fossil fuel plant operators, as well as wind farm and solar power operators, in collaborative efforts. PREPA has an agreement with Pattern Energy Group in which Pattern will supply more than 25,000 homes on the island with wind-generated power. The wind farm, completed in 2012, is the largest in Puerto Rico.

It is also building the Via Verde Pipeline to supply natural gas from north to south Puerto Rico. Switching power plants from expensive fuel oil to cheaper natural gas will save PREPA money in the long-term, but the pipeline itself will cost $74 million to complete. The overall infrastructure upgrade will cost $450 million, including the conversion of oil-fired power plants to natural gas.

In 2012 PREPA signed a 20-year power purchase agreement with Western Wind Energy Corp. for 30 MW pf solar photovoltaic power.

Company Background

Founded in 1941, PREPA is directed by a board of nine members, seven appointed by the Governor, and two elected by and representing clients. The utility operates 35 client service offices and 29 technical services offices.
