"Self-supply" and "no cost to ratepayers" can both be marketing. A June 8 Utility Dive analysis by two Energy Innovation experts argues that the corporate rush to build on-site natural-gas plants—meant to skip grid queues and utility charges—will raise gas and electricity prices for households anyway [1].

The logic is the part the slogan skips. Natural gas is a traded commodity; a data center that burns it competes with everyone else for the same supply and pipeline capacity, pushing prices up. Because gas-fired plants set the price of electricity in most hours and gas supplies roughly 43% of U.S. power, higher gas prices raise power bills too [1]. The frame extends the paper's June 15 reporting on how states moved to reprice the data-center subsidy era and how FERC pulled AI load into a who-pays docket—the grid-side counterpart to this off-grid receipt.

The buildouts are real and large: 2.2 GW at Richland Parish, Louisiana, and a Cheyenne, Wyoming, site scaling toward 10 GW [1]. Bloomberg analysts count roughly 100 GW of on-site gas capacity planned nationwide, and McKinsey estimates a quarter to a third of new data-center demand through 2030 will be met behind the meter [1][2].

A plant contracted to one data center sits outside state utility regulators' jurisdiction [1]. On X, that reads as escape—financing that lowers a tenant's costs. The unpriced spillover is the gas bill that arrives at houses nowhere near the turbines.
