The western United States is entering a period of unprecedented electricity demand growth driven by data center expansion, electrification, and new manufacturing activity. Utilities preparing integrated resource plans (IRPs) face a fundamental question: what new sources of clean, firm, dispatchable power can come online fast enough to meet this demand and help keep the United States at the forefront of innovation? Enhanced geothermal systems (EGS)—a next-generation technology that applies horizontal drilling and hydraulic fracking techniques from the oil-and-gas industry to unlock zero-carbon energy from the earth’s heat—offer a compelling answer. Unlike wind and solar, EGS produces power around the clock; unlike natural gas, it produces no carbon emissions and carries no fuel-price exposure. The permitting landscape reinforces the case: current federal regulations treat oil and gas projects on public lands more favorably than EGS, a disparity that policymakers and utilities alike have begun to recognize as an obstacle to grid resilience.
