AEE and Energiza Dispute Interconnection Costs for New San Juan Bay Power Plant

Published Sep 10, 2026 · via El Nuevo Día

Puerto Rico's Electric Power Authority (AEE) and the private consortium Energiza are at odds over how to split an estimated $168 million cost for transmission grid upgrades. These upgrades are needed to allow the electric grid to absorb 528 megawatts of power that will be produced by a new generating plant planned near San Juan Bay.

The article notes the project's operational start date has already been delayed by more than two years, now expected to begin at the end of 2030. The dispute centers specifically on which party—AEE or Energiza—will bear responsibility for financing the transmission improvements required to connect the new plant to the existing grid.
