Geothermal Energy: What a 33 MW First Unit Means for a USD 9.5 Billion Market
Executive summary. Geothermal energy uses heat from inside the earth to generate electricity and to heat and cool buildings, greenhouses and industry. Unlike solar and wind, it runs day and night, which makes it valuable for grids and for data centers that need firm, carbon-free power. For decades it was limited to places with hot water near the surface. New drilling techniques borrowed from the oil and gas industry, known as enhanced geothermal systems, are changing that. Strategic Revenue Insights projects the global geothermal energy market to reach approximately USD 9.5 billion by 2033, growing at a 5.8 percent compound annual growth rate from 2025. Demand for renewable energy, decarbonisation goals, technology advances and government incentives are driving it. This article sets out five lessons from the developers, technology providers and buyers moving first, with takeaways for strategy, product, operations, channels and revenue.
The structure of the market shows where growth is concentrating. Strategic Revenue Insights' Geothermal Energy Market research finds that binary cycle plants are the largest and fastest growing technology, that power generation is the largest end use while heating and cooling grows fastest, and that North America is the largest region while Asia Pacific grows fastest. The research names high upfront drilling and resource assessment costs and regulatory and environmental hurdles as restraints, identifies enhanced geothermal systems and hybrid projects as opportunities, and lists Ormat Technologies, Enel Green Power, Calpine, Chevron, KenGen, Contact Energy, Energy Development Corporation, Terra-Gen and Pertamina Geothermal Energy among the key companies.
Next-generation geothermal reached a commercial milestone in 2026. Fervo Energy's first 33 MW unit at Cape Station in Utah reached commercial operation in October 2026, with two more units in Phase I expected by January 2027 and a further 400 MW targeted for 2028, according to the company.
Why the Geothermal Energy Market Is Entering a New Phase
Three structural forces are converging.
Grids need firm clean power. As solar and wind grow, grids need power that runs around the clock. Batteries cover hours, as described in how battery energy storage is scaling, but geothermal can cover days and seasons.
Data centers will pay for 24/7 carbon-free electricity. AI computing loads run continuously, and their owners want clean power that matches every hour. The cooling and power demands behind this are explored in why liquid cooling is taking over AI data centers.
Drilling technology widens the map. Horizontal drilling and reservoir stimulation can create geothermal systems in hot rock that lacks natural water. SRI's research identifies enhanced geothermal systems as an opportunity and technology advances as a driver.
These forces explain SRI's forecast of steady growth to 2033, with value concentrating in binary plants, heating and cooling, enhanced systems and Asia Pacific.
Five Lessons From the Companies Moving First
The developers and buyers turning these forces into advantage share a recognisable pattern. We have distilled it into five lessons, each followed by a takeaway for a specific leadership function.
Lesson 1: Sell Firmness, Not Just Megawatt-Hours
Geothermal's value is that it is always on. The companies moving first sell that firmness through long-term power purchase agreements with utilities and technology companies that pay for round-the-clock clean power. Contracted offtake makes projects financeable before the first well is drilled.
"Geothermal does not compete with solar on price per megawatt-hour. It competes with gas on reliability, and wins on carbon."
Takeaway on strategy. Sell geothermal as firm, around-the-clock clean power, and secure long-term contracts with utilities and data center owners before major drilling.
Lesson 2: Standardise the Power Block
SRI's research identifies binary cycle plants as the largest and fastest growing technology. Binary plants can use lower-temperature resources, which widens the range of usable sites. The companies moving first standardise plant designs into repeatable blocks, as Fervo has done with its GeoBlocks, so each new unit is faster and cheaper to build.
Takeaway on product. Standardise plant designs into repeatable units, favour binary technology for lower-temperature resources, and design for modular expansion.
Lesson 3: Drilling Cost Decides Everything
SRI's research names high upfront drilling and resource assessment costs as the main restraint. The companies moving first borrow techniques, rigs and crews from the oil and gas industry, drill multiple wells from one pad, and use data to cut drilling time with each well.
Oil and gas companies themselves are entering the market, bringing subsurface expertise and capital. Chevron appears among the key companies in SRI's research.
"Every day cut from drilling a well takes a slice off the cost of geothermal power."
Takeaway on operations. Apply oil and gas drilling techniques and crews, drill several wells per pad, and track drilling time and cost per well as the core performance metric.
Lesson 4: Use Heat, Not Just Electricity
SRI's research identifies heating and cooling as the fastest growing end use, with greenhouse agriculture and aquaculture also significant, and residential as the fastest growing application. District heating networks, industrial process heat and ground-source heat pumps use geothermal directly, without converting it to electricity.
The companies moving first combine power with heat sales, partner with cities on district heating and supply industrial parks and greenhouses. Hybrid projects with solar or wind, an opportunity SRI identifies, add further value.
Takeaway on channels. Sell heat to district networks, industry and greenhouses alongside power, partner with cities and industrial parks, and design hybrid projects with solar and wind.
Lesson 5: North America Leads, Asia Pacific Grows Fastest
SRI's research identifies North America as the largest region and Asia Pacific as the fastest growing, with Indonesia and the Philippines among the fastest growing countries. Volcanic resources, rising power demand and government programmes drive Asian growth, while enhanced systems are opening new areas in the United States.
The capabilities that decide who captures this demand are specific:
Long-term contracts for firm clean power.
Standardised binary plant designs.
Low-cost drilling borrowed from oil and gas.
Heat sales and hybrid projects.
Development partnerships in Indonesia, the Philippines and the United States.
Companies evaluating these competitive dynamics in greater detail can use SRI's Geothermal Energy Market analysis to assess technology, application and end-use segments and the positioning of the leading developers.
Takeaway on market development. Partner with governments and state utilities in Indonesia and the Philippines, and use enhanced systems to open new regions in North America.
Where the Opportunity Is Concentrating
Value is moving toward binary plants, heat applications, enhanced systems and Asia Pacific.
By technology, binary cycle is the largest and fastest growing.
By end use, power generation is the largest and heating and cooling grows fastest.
By application, industrial is the largest and residential grows fastest.
By geography, North America leads and Asia Pacific grows fastest.
At the Horizon: What to Watch Over the Next Three Years
Enhanced geothermal cost curve. Drilling cost and output from the first commercial enhanced projects will show how far the technology can spread.
Data center contracts. New power purchase agreements with technology companies will signal demand for firm clean power.
Permitting reform. Faster permitting on public land would shorten development timelines.
"The next phase of geothermal will be won by developers who drill faster, build in repeatable blocks and sell firm clean power to buyers who need it every hour."
The Strategic Revenue Opportunity
For developers, the task is to cut drilling cost and secure firm power contracts. For technology providers, the opportunity lies in binary plants, drilling tools and reservoir services. For utilities and data center owners, the priority is round-the-clock clean power. For investors, the signal is cost per well, contracted capacity and new project milestones.
Market intelligence turns these questions into decisions. Segment-level analysis shows where technology and end-use demand is concentrating, competitive analysis shows how developers are positioned, and regional analysis shows where resources and policy will pull growth first. This is the path from market signals to strategic insight to revenue impact.
Takeaway on revenue. Treat the geothermal energy market as four revenue pools: firm power sold under long-term contracts, heat sold to district networks and industry, drilling and plant technology sold to developers, and hybrid and storage services sold to grids. Each needs its own pricing model.
The Next Leg: Preparing for the Journey Ahead
The defining shift in geothermal energy is that it is moving from a resource limited by geology to an engineered source of firm clean power. That changes where projects can be built, how they are financed and who buys the output. The companies moving first are not the ones with the hottest sites; they are the ones selling firmness, standardising plants, cutting drilling cost, selling heat and expanding where growth is fastest.
The next three years will decide which developers become the default suppliers of always-on clean energy. Decision-makers should invest in drilling efficiency, standard plants and long-term contracts and track enhanced system costs, data center demand and permitting.
