The San Juan power plant has operated on diesel fuel since September 16 due to unavailability of natural gas. [^1]

The switch followed a berthing delay at San Juan Bay. Running on diesel instead of natural gas has tripled electricity generation costs for Puerto Rico ratepayers. [^3] [^6]

Puerto Rico's Office of Independent Acquisitions, 3PPO, is working to define a mechanism to restore gas access at the plant. 3PPO president Osvaldo Carlo Linares expressed confidence an emergency liquefied natural gas supply agreement could be finalized by September 24. [^2] [^4] [^5]
