At a glance
PREPA and Energiza consortium are in dispute over $168 million in interconnection costs
The new power generation plant will produce 528 MW
The project’s operational start date has been delayed until the end of 2030
Why this matters: The delay and cost issues with the new power plant and transmission grid upgrades may impact the reliability and cost of electricity for Puerto Rican households and businesses.
Puerto Rico’s Electric Power Authority (PREPA) 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 dispute centers specifically on which party—PREPA or Energiza—will bear responsibility for financing the transmission improvements required to connect the new plant to the existing grid.
