Executive Summary
Ormat Technologies
The rise of artificial intelligence has created a power problem. Data centres need vast amounts of electricity that runs constantly, and they need it to be clean to meet corporate carbon targets. Wind and solar cannot supply it on their own because they stop when the weather changes. Geothermal energy, drawn as heat from deep underground, runs day and night regardless of conditions, which is why technology giants are now signing long-term deals to secure it.
Ormat Technologies (NYSE: ORA) is the only pure-play geothermal company listed on a public market, and it does the whole job itself: it designs its own turbines, builds its own plants, and owns the assets that sell power under long contracts. That end-to-end model is hard for rivals to copy. Three things are drawing investors now: long-dated power contracts with hyperscalers that are repricing higher, a fast-growing energy-storage arm, and the early promise of new drilling technology that could let geothermal work almost anywhere. The main debate is whether Ormat can deliver an ambitious buildout without stumbling on cost or execution.

Why Invest?
Key pieces of information about the business that you need to know about.
The only listed way to own geothermal at scale
Investors who want exposure to geothermal energy have very few options, and Ormat is effectively the only liquid one. It is fully vertically integrated, designing its turbines, building its plants and operating the generation assets that produce contracted revenue. No competitor matches that full-stack model at this size, and no other public company offers institutional-grade geothermal exposure. Most of Ormat's electricity is sold under long-term contracts, which gives the business recurring, predictable cash flows and a degree of stability unusual for a growth-stage energy company.
Power contracts that are repricing higher
Geothermal is the one renewable that delivers steady, around-the-clock power without batteries or backup, and that scarcity is showing up in pricing. Ormat has signed a 20-year, 150MW agreement to supply Google's Nevada data centres through utility NV Energy, plus a 20-year deal with data-centre operator Switch. It recently renewed a set of California contracts at about 27% above the previous rate while extending them to 2037. As power markets tighten and more technology firms compete for clean baseload supply, Ormat's contracted base is repricing upward, which lifts the value of assets it already owns.
A storage business that has become a real profit driver
Ormat's Energy Storage arm has shifted from a small side activity into a genuine contributor. In the first quarter of 2026 its revenue grew 153% year-on-year, and its margins expanded sharply as new capacity captured favourable market pricing. Pairing batteries with geothermal also makes Ormat's overall power offering more attractive to data-centre customers, who cannot tolerate interruptions. New storage projects across Texas, California and Israel extend the runway. The caveat, addressed in the risks, is that some of those strong margins reflect short-term market conditions rather than a permanent level.
Catalysts
The key events that could drive investment opportunities and shift markets.
More hyperscaler contracts at premium prices: Additional data-centre deals on the terms Ormat has recently won would lift contracted revenue and analyst estimates.
Storage proving its margins are durable: Further quarters of strong, stable storage profitability would confirm it as a lasting growth engine rather than a one-off.
Delivering the contracted capacity on time: Bringing the Google and other new projects online to schedule would build confidence in the wider buildout.
Energy-storage expansion across regions: New projects in Texas, California and Israel add capacity and diversify the revenue base.
Next-generation geothermal reaching commercial scale: If enhanced geothermal, which Ormat is developing with partners SLB and Sage Geosystems, moves from pilot to commercial, the addressable market could expand dramatically.
Geothermal following the nuclear adoption curve: Growing recognition of geothermal as reliable, clean baseload power, reinforced by sector momentum, could re-rate the whole industry over time.
Key Risks
Key pieces of information about the business risks that you need to know about.
Margins may not hold after the storage surge
The recent profitability of the storage business is striking, but part of it comes from favourable short-term market pricing rather than a settled level. Group gross margin actually slipped in 2025 even as revenue grew. If merchant power prices normalise or cost inflation returns, earnings could grow more slowly than the headline revenue figures suggest. Investors should watch whether storage margins hold up over several quarters or fade once the current pricing window closes.
A large buildout carries real execution risk
Ormat is targeting a substantial increase in capacity across the United States, Indonesia and Israel, and large energy projects are prone to permitting delays, cost overruns and grid-connection bottlenecks. The Google contract, for example, requires delivering new capacity across multiple projects by 2030. Management has already flagged that one storage facility slipped to 2028 because of permitting. Each delay chips away at credibility and pushes back the cash flows the contracts promise.
A premium valuation leaves little room for error
Ormat trades at a high multiple of earnings for an energy company, which means the market is already pricing in successful delivery. Any meaningful miss on growth, margins or the progress of its new drilling technology could trigger a sharp fall in the shares. The company also recently raised $1bn through convertible notes, which adds to its debt and creates some dilution risk, and the scale of its investment plans may require further fundraising while interest rates remain elevated.

What the Pros are asking
Here are the questions that professional investors are asking before making an investment decision.
Is the data-centre demand a lasting driver or a passing theme?
Bulls argue the shift is structural: AI data centres need clean power that runs constantly, and geothermal is one of the few sources that delivers it, which is why Google, Microsoft, Meta and others are signing long contracts. Sceptics counter that some of this demand could be met by enhanced geothermal newcomers, nuclear, or simply cheaper gas if clean-power premiums fade. The evidence so far favours the bulls, with multiple 15- and 20-year agreements already signed at premium rates, but the durability of that pricing is the thing to watch.
Are the recent margins real or temporary?
This is the central financial debate. The Energy Storage segment posted exceptional margins in early 2026, but a chunk of that came from capturing favourable merchant power prices, which are by nature volatile. At the same time, group gross margin dipped in 2025. The bull view is that scale and tax advantages make the storage business durably profitable; the bear view is that normalised pricing brings margins back down. Resolving it requires several more quarters of data, and it matters because the valuation assumes margins hold.
Can Ormat execute a buildout of this size?
Ormat's growth plans span several countries and require new wells, plants and grid connections, each a potential point of failure. Supporters point to a five-decade operating history and proven engineering as reasons to trust delivery. Doubters note that the company has already pushed back one project on permitting, and that the Google contract sets a firm 2030 deadline for substantial new capacity. The question is less whether Ormat can build, and more whether it can build at the pace and cost its contracts and valuation assume.
How should investors think about the valuation and the debt?
Ormat trades at a premium multiple, and it recently took on $1bn of convertible debt to fund growth. Bulls argue the premium is justified by scarcity value, long-dated contracted revenue and a genuine growth runway. Bears see limited margin for error: if growth or margins disappoint, the shares could de-rate sharply, and further capital raises could dilute existing holders. The balance rests on whether the contracted cash flows and storage growth compound fast enough to grow into the valuation.
What is enhanced geothermal really worth to Ormat today?
Enhanced geothermal systems, which use drilling techniques to create geothermal capacity where natural reservoirs do not exist, could in theory expand the market enormously. Ormat is developing pilots with SLB and Sage Geosystems, and rival Fervo's strong public-market debut has drawn attention to the technology. The realistic view is that this is option value rather than near-term earnings: the pilots are small and commercial scale is years away. Investors should treat it as a potential long-term upside, not a reason the current numbers work.
