Mexico’s underutilized geothermal resources are receiving renewed attention through a joint initiative involving Pemex, the Mexican Petroleum Institute (IMP), the National Autonomous University of Mexico (UNAM), and the National Institute of Electricity and Clean Energy (INEEL). With support from the Energy Ministry (SENER), the project aims to elevate geothermal energy from its marginal role—just 1.8% of the national energy matrix at the end of 2025—into a strategic component of the country’s energy transition.
The collaboration marks a departure from Mexico’s historically fragmented approach to clean energy development. Institutional representatives describe it as a paradigm shift toward coordinated deployment of scientific, technical, and operational capabilities. The project, which began conceptual development in 2024, is now entering implementation, with exploratory work already underway in several regions. Its backers hope it will become a reference point for future public-sector-led renewable energy efforts.
Despite Mexico’s favorable volcanic and tectonic geography, geothermal energy has long lagged behind other renewables such as wind and solar, which accounted for 12% and 10.7% respectively of the energy mix at the close of 2025. Hydroelectric and nuclear sources contributed 16.1% and 5.5%. The reasons for geothermal’s slow uptake are well known: high capital costs, long development timelines, and subsurface exploration risks have deterred broader investment.

Pemex’s involvement adds both weight and complexity. While its technical expertise in subsurface operations is relevant, the company’s financial constraints and operational inefficiencies raise questions about execution capacity. Still, proponents argue that leveraging existing institutional infrastructure—particularly through collaboration with research entities like UNAM and INEEL—could mitigate some of these challenges.
The initiative also reflects broader policy ambitions to foster technological self-sufficiency. Stakeholders emphasize the need to develop domestic capabilities in geothermal innovation to reduce reliance on imported systems. This aligns with official rhetoric around energy sovereignty, though realizing such ambitions will require sustained investment in R&D and institutional continuity across political cycles.
Whether this project can overcome Mexico’s historical hurdles in geothermal development remains uncertain. Bureaucratic inertia and shifting political priorities could hamper momentum. Yet the current alignment between research institutions, a state-owned enterprise, and federal authorities offers a rare window for coordinated action in a sector that has struggled to scale.
For investors eyeing Mexico’s clean energy landscape, the geothermal push underscores both opportunity and caution. As global capital increasingly seeks sustainable infrastructure assets, underexploited segments like geothermal may attract interest—provided regulatory clarity, technical capacity, and institutional coordination improve in tandem.
