When the 2022-2026 Multi-Year Program Plan was published, the Geothermal Technologies Office (GTO) operated with the former Office of Energy Efficiency and Renewable Energy. As of early 2026, the office has been renamed the Office of Geothermal and now operates within the Hydrocarbons and Geothermal Energy Office (HGEO).
In addition to being subject to merit review and regular check-ins, GTO-funded projects are evaluated throughout execution. In-progress reviews include state-gate reviews, go/no-go decisions, GPRA targets, and quarterly project milestones. These ongoing assessments occur at specified intervals that are negotiated as part of the project award phase. Stage-gate reviews and go/no-go decisions ensure that a project is meeting agreed-upon goals or technology advancements; if not, the project may be renegotiated or even canceled. GTO also monitors progress of awarded projects through regular project check-in meetings, peer review, and other activities.
