About Sempra
Sempra is an energy infrastructure holding company with three main platforms. Oncor, its largest business, delivers electricity across much of Texas. San Diego Gas & Electric and SoCalGas serve California, and Sempra Infrastructure develops LNG export and other energy projects. Earnings come mostly from regulated utility rates.
The AI story runs through Texas. Oncor sits at the center of the state's data center boom, with an ERCOT interconnection queue holding more than 100 gigawatts of requests, including large AI campuses. Serving that demand requires record transmission investment, which grows the regulated asset base Sempra earns on.
Formed in 1998 and headquartered in San Diego, California, Sempra employs about 15,938 people and trades on the NYSE.
Sempra in the AI buildout
Sempra sits in the Utilities & Grid layer of the AI buildout through Oncor, its Texas transmission and distribution utility. Texas has become a leading destination for AI data centers, and Oncor must build the wires to connect them, with an interconnection queue in ERCOT that exceeds 100 gigawatts of requests. That buildout drives Sempra's record capital plan. California utilities and LNG infrastructure diversify the company away from AI, which is why Supercycle scores the exposure in the Growing band.
SRE is tracked in Utilities & Grid, rated Growing on the AI Exposure leaderboard.
