June 10 (Reuters) - Energy infrastructure company Sempra SRE.N said on Wednesday that it has received approvals for new transmission projects in Texas which, along with earlier go-aheads, are expected to cost more than $7 billion.

The approvals for the new projects came last week from the Electric Reliability Council of Texas (ERCOT), the operator of the electricity grid in the state.

U.S. power demand hit record levels in 2025 and is expected to grow again this year, according to the U.S. Energy Information Administration, as tech companies rapidly build out data centers, some of which use as much electricity as an entire city at a single site.

Sempra's latest projects, which include new lines in the southern Dallas-Fort Worth area and along the I-35 corridor along with upgrades approved in April, are expected to support about 16 gigawatts of new power demand.

Power companies across the U.S. are raising prices and ramping up capital spending to expand infrastructure as they race to meet surging demand from tech giants.

Oncor Electric Delivery Company, in which Sempra owns an 80.25% stake, expects to construct the majority of the projects.

The projects are expected to come online between 2026 and 2034.
