Overview

Natural Gas Power Generation covers electricity produced from natural gas — the largest single source of U.S. electricity and the reliability backbone of the grid. At ~$86B (the combined fossil-fuel generation category) it spans combined-cycle and peaking plants operated by utilities and independent power producers (Vistra, Calpine, NRG), with natural gas the dominant and growing component.

Demand is driven by gas's role as flexible, dispatchable baseload and peaking power that complements intermittent renewables, plus low-cost shale gas. It is central to grid reliability amid the energy transition, increasingly valued for firming renewables and meeting data-center load growth, even as its long-term role faces decarbonization questions. It is consolidating among IPPs and utilities.
