COWI and Sinotech Team Up on Taiwan’s Super-Hot Geothermal Potential Taiwan’s geothermal story is moving from possibility to execution, and the COWI-Sinotech collaboration is a sign that the sector is entering a more serious phase of development. The partnership is focused on unlocking super-hot geothermal resources, which could improve project economics and expand the country’s clean-energy options. Introduction Geothermal has long been one of Taiwan’s most intriguing renewable resources because the island sits on active tectonic terrain with strong heat potential. What has held the sector back is not a lack of heat, but the difficulty of converting that heat into bankable projects at scale. The new collaboration between COWI and Sinotech points to a more technical, internationally connected approach to solving that problem. Why Taiwan Matters Taiwan has ambitious decarbonization goals, and geothermal fits neatly into the need for firm, low-carbon power. Unlike solar and wind, geother...
New Mexico’s Tribal Lands Poised for Geothermal Development: Opportunity, Challenges, and Pathways to Energy Sovereignty
Why geothermal matters for New Mexico tribes, nations, and pueblos
Geothermal energy uses heat from the earth to produce electricity or heat buildings directly. For New Mexico — a state with abundant subsurface heat resources — geothermal offers a reliable, low‑emission complement to wind and solar. Unlike intermittent renewables, geothermal provides baseload power capable of supporting grid stability and reducing reliance on fossil fuels. For tribal communities, geothermal has particular appeal: it aligns with many Indigenous values around stewardship, can be developed with relatively low water demand compared with some thermal technologies, and offers long‑term revenue, jobs, and enhanced local control over energy resources.
Evidence of resource potential under tribal lands
A 2025 collaborative report from Project InnerSpace, New Mexico Tech, and the New Mexico Bureau of Geology and Mineral Resources mapped subsurface heat and concluded that “a significant amount of Tribal land sits on top of some of the best subsurface heat.” Geological indicators include shallow temperature gradients, hot springs and fumaroles, and structural features favorable for permeability. Southern New Mexico already hosts operational geothermal facilities that demonstrate commercial viability in the state’s geology. Taken together, these signals show meaningful potential for scaling geothermal exploration and production on tribal lands across New Mexico.
Economic and social benefits for Indigenous communities
Revenue generation: Geothermal plants can produce steady electricity sales and provide opportunities to sell excess power into wholesale markets or to utilities under long‑term power purchase agreements (PPAs).
, Job creation: Construction, drilling, reservoir management, plant operations, and ongoing maintenance create both short‑term and long‑term employment. Workforce development programs can prioritize tribal members.
, Local economic development: Plant construction and operation stimulate local supply chains, services, and small‑business growth.
, Energy sovereignty: Owning and operating generation assets enables tribes to reduce energy costs, improve reliability, and exert greater control over lifeline services (water pumping, heating, refrigeration).
, Climate and cultural alignment: Low emissions and reduced fossil fuel dependence can align with tribal climate goals and cultural priorities for land stewardship.
Types of geothermal development suitable for tribal lands
Conventional hydrothermal plants: Utilize natural reservoirs producing steam or hot water to drive turbines. Best where natural permeability and fluids exist.
, Enhanced Geothermal Systems (EGS): Stimulate hot, low‑permeability rock to create a heat exchanger. EGS expands usable areas beyond natural hydrothermal resources and could unlock resources beneath large parts of New Mexico.
, Direct‑use applications: Use geothermal heat for district heating, greenhouse/agricultural applications, industrial process heat, or aquaculture—particularly attractive for communities seeking non‑electric heat solutions.
, Hybrid systems and co‑location: Geothermal with solar or battery storage can optimize dispatchability and grid services; co‑locating with mineral extraction or brine‑resource recovery (e.g., lithium) can add revenue streams.
New Mexico’s Energy Transition Act (ETA) sets aggressive renewable portfolio targets: 50% renewable by 2030, 80% by 2040, and 100% by 2045. These mandates create market demand for clean generation, improving the commercial case for geothermal. State programs and federal incentives, including the Inflation Reduction Act’s tax credits and loan programs from the Department of Energy and USDA, further reduce capital costs. However, regulatory complexity — especially around tribal sovereignty, federal land management, permitting, and environmental review — requires coordinated policy support to streamline development while protecting tribal rights and environmental values.
Tribal ownership: Full tribal ownership maximizes long‑term revenue and sovereignty but requires upfront capital and technical capacity.
, Joint ventures: Partnerships with experienced developers and utilities can share risk and provide technical expertise while ensuring tribal equity stakes.
, Community benefit agreements: Contracts can include local hiring, training, and revenue-sharing provisions.
, Public funding and incentives: Federal grants (e.g., DOE geothermal demonstration funds), tax credits (where transferable or monetized via partnerships), state grants, and low‑interest loans can lower capital barriers.
, Power purchase agreements: Long‑term PPAs with utilities like PNM provide revenue certainty but require creditworthy counter‑parties and price negotiation.
Technical and operational challenges
Resource risk: Early‑stage exploration carries high uncertainty. Drilling is expensive and may not encounter commercial temperatures or permeability.
Water and environmental constraints: Although geothermal often uses less water than thermal plants, some projects require fluid management and can encounter water‑rights issues in arid regions.
Grid interconnection and transmission: Remote tribal sites may lack existing transmission capacity; upgrades add cost and time.
, Skilled workforce needs: Technical roles in drilling, reservoir engineering, and plant operation require training programs and certification pathways.
, Long development timelines: From exploration to commercial operation can take several years, requiring patient capital and sustained permitting efforts.
Best practices for tribal-led geothermal development
Community engagement and consent: Early, transparent consultation preserves tribal authority and integrates cultural considerations into siting and design.
, Resource assessment first: Phased exploration—geophysical surveys, temperature gradient wells, and slimhole drilling—reduces risk before committing to full‑scale drilling.
, Build local capacity: Invest in apprenticeships, technical training, and partnerships with universities (e.g., New Mexico Tech) to grow tribal technical expertise.
, Use flexible project structures: Consider staged development, joint ventures, and community investment vehicles to balance risk and control.
, Environmental stewardship: Apply culturally appropriate environmental assessments and mitigation strategies, including groundwater protection, seismic monitoring for EGS, and careful management of drilling wastes.
, Revenue-sharing frameworks: Draft clear agreements for profit distribution, local procurement, and workforce priorities to ensure equitable benefits.
Case study: PNM and southern New Mexico geothermal
New Mexico’s largest electric provider, PNM, has tapped into a southern New Mexico geothermal plant to generate electricity, demonstrating operational feasibility. That project provides a replicable model: partnering utilities and developers can build commercially viable plants in the state’s geological settings. Key lessons include the importance of robust subsurface characterization, negotiated interconnection arrangements, and long‑term contracts that support financing.
Opportunities for collaboration and capacity building
Tribal consortia: As Rep. Patricia Roybal Caballero suggested, tribes pooling resources into a joint development group can create scale, reduce per‑project costs, and strengthen negotiating power with developers and utilities.
, Academic partnerships: New Mexico Tech, tribal colleges, and federal labs (e.g., Sandia, Los Alamos) can provide technical assistance, research collaboration, and training.
, Federal and state technical assistance: Leverage DOE’s geothermal programs, BIA resources, and state agencies to obtain technical, legal, and financial support targeted to tribal applicants.
, Private sector partnerships: Carefully structured joint ventures can provide drilling and operational know‑how while protecting tribal interests through equity stakes and governance provisions.
Environmental and cultural safeguards
Tribal-led geothermal projects should embed protections for sacred sites, traditional use areas, and ecological values. Cultural resource surveys, tribal cultural monitors during construction, and defined protocols for any discoveries maintain cultural integrity. Environmental safeguards include groundwater monitoring, closed‑loop fluid systems where feasible to limit surface discharges, and seismic monitoring programs for stimulation activities in EGS projects.
Portfolio approach: Developing multiple smaller projects or combining direct‑use and power projects spreads exploration risk.
, Front‑end investment in exploration: More detailed geophysics and slimhole wells reduce the probability of failed production wells.
, Insurance products: Well‑failure and resource‑risk insurance (where available) can make projects bankable.
, Contractual protections: Including step‑in rights, vendor warranties, and milestone‑based payment structures protects tribal owners during development.
Timeline and milestones for a typical tribal geothermal project
Phase 1 (0–18 months): Resource assessment, community consultation, permitting strategy, and initial financing.
Phase 2 (12–36 months): Exploration drilling (temperature gradient and slimhole wells), detailed feasibility studies, environmental reviews.
Phase 3 (24–60 months): Production drilling, plant design and construction, interconnection works.
Phase 4 (after 36–60 months): Commissioning, operations, and revenue generation.
Timeframes overlap and depend on financing speed, permitting, and exploration success.
Policy recommendations to accelerate tribal geothermal development in New Mexico
Create a tribal geothermal development fund or grant program to underwrite early exploration costs.
, Streamline permitting with a tribal‑led pathway that respects sovereignty and expedites environmental reviews without cutting protections.
, Support transferable tax credit mechanisms or state‑level credit monetization to help tax‑exempt tribal entities access incentives.
, Invest in workforce development through scholarships, apprenticeships, and technical training focused on geothermal skills.
, Prioritize transmission investments that serve tribal communities and connect geothermal generation to markets.
, Facilitate tribal consortia formation with legal and financial advisory support.
Conclusion: A strategic opportunity for energy sovereignty and economic resilience
New Mexico’s tribal, nation, and pueblo lands sit atop geothermal resources that could meaningfully contribute to the state’s clean energy transition while delivering direct benefits to Indigenous communities. Achieving that promise requires careful resource assessment, culturally informed planning, accessible financing structures, and supportive policy frameworks. By pooling resources, building technical capacity, and leveraging state and federal incentives, New Mexico tribes can transform subsurface heat into long‑term jobs, revenues, and enhanced energy sovereignty.
