About

The LADWP-Q44 development project is a proposed 450 MW hybrid solar and battery energy storage project located in Millard County, Utah. The project, developed by Intermountain Power Agency, consists of a 300 MW solar array coupled with a 150 MW battery. Interconnecting to the Los Angeles Department of Water and Power (LADWP) grid at the IPP 345kV Switchyard, the project entered the LADWP interconnection queue on September 4, 2013, with a proposed commercial operation date of December 31, 2018. The project's interconnection agreement (IA) status is listed as Operational.

The LADWP-Q44 project has been featured in recent news coverage related to grid infrastructure.
