XGS New Mexico

Executive Overview

XGS New Mexico is a 150 MW advanced geothermal project under development in New Mexico by XGS Energy under a two-phased power purchase agreement with Meta, announced in June 2025. Both phases are projected to be operational by 2030 and will deliver power to the PNM electric grid to support Meta's data centre operations in the state. XGS Energy's technology enables geothermal power generation without operating water, making it deployable in geological settings that conventional geothermal cannot access. Construction on the Meta project is expected to commence in 2026. XGS has secured strategic supply chain partnerships with Vallourec (tubular supply and engineering, January 2026) and Baker Hughes (exploration and engineering services, February 2026) as it advances the project. The project will increase total geothermal electricity produced in New Mexico by a factor of ten from the current single operating plant, drawing on the state's estimated 160 GW of untapped geothermal potential.

How It Works & Differentiation

XGS Energy's system uses a closed-loop, solid-state heat exchanger approach in which a working fluid is circulated through a pipe-in-pipe well configuration drilled into hot subsurface rock, extracting thermal energy without extracting geothermal brine or requiring permeable rock formations. The process is water-independent — the working fluid operates in a zero-loss closed loop — and the smallest modular unit is a single well. This architecture decouples geothermal power from the traditional geological constraints of hydrothermal systems, enabling deployment based primarily on subsurface temperature rather than permeability or natural fluid presence. XGS completed a 3,000-hour commercial-scale demonstration of its technology in an existing California well in late 2025, providing the field-scale validation underpinning the New Mexico construction decision.

Commercialization & Traction

Meta's commitment as offtaker under a two-phased agreement provides revenue certainty across both project phases and represents one of the largest advanced geothermal commitments by a major technology company to date. XGS Energy has a 3 GW geothermal project pipeline, with construction expected to commence on the New Mexico project in 2026. The Vallourec partnership secures long-lead tubular supply for XGS's well construction programme; the Baker Hughes collaboration adds exploration and engineering depth from an operator with decades of complex energy infrastructure experience. The project is expected to result in approximately $1 billion in private sector investment and create 3,000 construction jobs and 100 plant operations jobs.

Scalability & Strategic Context

New Mexico has only one currently operating geothermal power plant, meaning the XGS project would represent a step-change in the state's geothermal capacity. The technology's location-independence substantially expands the viable geography for geothermal development across the western United States and beyond. Meta is among the world's largest corporate clean energy buyers, and its investment in XGS's New Mexico project follows a broader portfolio of advanced energy agreements — signalling an appetite for firm, 24/7 carbon-free power from diverse technology pathways. Success here would provide the first large-scale operational reference for XGS's platform and support the company's broader 3 GW pipeline.
