Two generating units at the San Juan power plant have been operating on diesel instead of liquefied natural gas due to delayed deliveries, raising generation costs and residential power bills.[^1]

This diesel reliance at San Juan and Palo Seco plants has now run for more than two weeks. Temporary backup generation units are deployed at both sites.[^3] [^4]

Lawmakers plan to review the existing New Fortress Energy contract for San Juan Bay docks A, B and C during the upcoming hearing process.[^2]
