Adelanto Converter Station

Adelanto Converter Station in Adelanto, California, is the southern terminus of the 2,400 MW Path 27 Utah–California high voltage DC power (HVDC) transmission line. The station contains redundant thyristor-based HVDC converters rated for 1,200 MW continuous or 1,600 MW short term overload. The 300 acre station was completed in July, 1986 at a cost of US$131 million. The northern terminus of Path 27 is fossil fueled Intermountain Power Plant in Utah.

An adjacent $45 million AC switching station owned by Los Angeles Department of Water and Power links to the Southern California grid via five 500-kV AC lines.

ABB, who had built the station in 1986, upgraded its original 1,600 MW capacity to 2,400 MW in 2011.

In 2012, an 11.4 MW solar array (less than 1% of the Utah plant's capacity) was installed at the facility at a cost of $48 million obtained with loans subsidized by the American Recovery and Reinvestment Act of 2009.
