NRG Energy, Inc. is one of the largest retail energy providers in the United States, serving approximately 6 million customers. Following its 2023 acquisition of Vivint Smart Home, the company added about 2 million home-services customers. NRG is also among the largest independent power producers in the US, with 13 gigawatts of coal-, gas-, and oil-fired generation capacity, primarily located in Texas. The acquisition of LS Power assets adds another 13 GW of gas-fired power plants, mostly in the Eastern United States. NRG emerged from Chapter 11 bankruptcy as an independent company in December 2003.
