Puerto Rico's Electrical Grid: A History of Colonial Infrastructure

Puerto Rico's electrical infrastructure tells the story of colonialism in wires and transformers.

PREPA (AEE): The Puerto Rico Electric Power Authority (PREPA / Autoridad de Energía Eléctrica) was created in 1941 as a government-owned utility. It is the sole provider of electrical power to the island.

Colonial Design Flaws:
- Centralized generation: Power plants concentrated on the southern coast, with transmission lines crossing the mountainous interior to the population centers in the north — an inherently fragile design
- Fossil fuel dependency: 97% of electricity generated from imported fossil fuels (oil, natural gas, coal), making Puerto Rico dependent on volatile global fuel markets and vulnerable to shipping disruptions
- Deferred maintenance: Chronic underinvestment left infrastructure aging and fragile
- Debt burden: PREPA accumulated $9 billion in debt, with Wall Street banks earning hundreds of millions in fees
- Political patronage: PREPA was used as a source of political employment, with staffing levels well above industry norms

The María Collapse: Hurricane María destroyed the entire electrical grid on September 20, 2017:
- 100% of customers lost power — 3.4 million people
- The longest blackout in U.S. history (up to 11 months in some areas)
- The last customers received power in August 2018
- Total grid restoration cost estimated at $17-20 billion

LUMA Energy (2021-present): In June 2021, grid management was privatized under a 15-year, $1.5 billion contract to LUMA Energy (Quanta Services / ATCO Ltd.). Results have been poor:
- Outage frequency and duration have increased
- Rates have risen significantly
- Customer complaints have surged
- Multiple island-wide or near-island-wide blackouts since LUMA took over

Energy Sovereignty Movement: In response to grid failures, a growing movement advocates for distributed, renewable energy:
- Community solar projects (like Casa Pueblo in Adjuntas)
- Rooftop solar installations have surged
- Advocates argue that energy sovereignty is inseparable from political sovereignty

The electrical grid represents the colonial infrastructure paradox: a system designed to serve the colony's industrial needs rather than its people's welfare, maintained through debt rather than investment, and now privatized to a mainland corporation that is accountable to shareholders rather than to Puerto Ricans.
