Reliable, 24/7 carbon‑free energy.

We develop, own, and operate geothermal power projects across North America, delivering clean, firm power to the grid.

A scalable, financeable model for geothermal energy.

The opportunity for geothermal energy across North America is significant and largely underdeveloped. Accelerating power demand, driven by electrification, data center growth, and U.S. reindustrialization is creating structural demand for the clean, around-the-clock generation that geothermal uniquely provides.

Historically, large-scale geothermal development has been constrained by resource risk, high upfront capital costs, and limited pre-construction financeability. Mantle Reach Power was formed to solve for this. Through community and customer-focused development, partnerships with best-in-class technical providers, and a commercial architecture structured to provide resource certainty, we are building a portfolio designed to access traditional project finance markets and deliver capacity at scale.

Mantle Reach Power is a portfolio company of EnCap Energy Transition Fund III.
