Sale of block at Mesquite power plant in Arizona to ArcLight has been done

Mesquite Power LLC told the Federal Energy Regulatory Commission in an April 14 notice that a deal the commission approved last December for Mesquite Power Holdings LLC to acquire 100% of the direct membership interests in Mesquite Power closed on April 9.

The prior owner of Mesquite Power had been Sempra Generation LLC, with the sale being made to Mesquite Power Holdings, an affiliate of ArcLight Capital Partners LLC. Mesquite Power owns the 625-MW Block 2 of the Mesquite Generating Station and certain interconnection facilities located in Maricopa County, Arizona. The Mesquite Generating Station is interconnected to the Hassayampa Switchyard, which was built as a satellite extension of the Palo Verde Switchyard, together forming a commission-approved “Common Bus.”

Mesquite Power had been a wholly-owned, direct subsidiary of Sempra Generation, which in turn is a wholly-owned indirect subsidiary of Sempra Energy, the public utility holding company based in San Diego.
