Ormat Technologies is a renewable energy company that owns and operates a global portfolio of geothermal power plants while building storage facilities for the modern grid. It generated $880 million in revenue during 2024, a 6.1% increase over the prior year, supported by a total generating capacity of 1,538 megawatts. As the only major renewable energy provider focused on 24/7 baseload power, the company holds a unique position in a market otherwise dominated by intermittent wind and solar.
The investment thesis on Ormat Technologies is that it owns the only renewable energy source that can provide steady electricity around the clock, making its power more valuable to utilities than weather-dependent alternatives. Unlike solar or wind, geothermal energy relies on the Earth's internal heat to spin turbines constantly. This gives Ormat a defensive utility profile with the growth potential of a technology manufacturer.
We think Ormat is a high-quality infrastructure business currently trading at a price that leaves no margin for error or project delays. The business has a genuine competitive edge in geothermal technology, but the heavy capital requirements for drilling make it a expensive company to run. The primary challenge for investors is waiting for the massive construction pipeline to finally turn into free cash flow.
Ormat Technologies stock has climbed steadily for years because it provides a rare, reliable way to generate clean electricity around the clock. The company grew its business by building bigger geothermal plants and battery systems for the power grid. While the stock dipped slightly last month, it has jumped significantly over the past year.
What does it do?
Ormat Technologies is a maturing utility and manufacturing business that earns money by selling electricity from its own geothermal plants and selling geothermal equipment to other developers. The company is vertically integrated, meaning it designs the power plants, manufactures the turbines, and then owns and operates the facilities. Money flows primarily through long-term contracts called Power Purchase Agreements (PPAs), where utilities agree to buy electricity at a fixed price for 15 to 25 years. This provides a steady, predictable income stream similar to a traditional utility, but with the added upside of a manufacturing segment that sells its proprietary technology to third parties.
Where does revenue come from?
The majority of Ormat's revenue comes from its Electricity segment, which sells power generated from its geothermal and solar assets. This core business accounts for the bulk of the $880 million in 2024 revenue. The Product segment generates revenue by designing and building geothermal power plants for others, while the fast-growing Energy Storage segment earns money by providing capacity and balancing services to the electric grid. Geographically, the company is global, with major operations in the United States, Kenya, Indonesia, and Central America.
Revenue Breakdown
Revenue by Geography
Who are its customers?
Ormat Technologies serves large utility companies and government-owned power agencies across more than 30 countries. At the end of 2024, the company managed a total generating portfolio of 1,538 megawatts, which includes 1,248 megawatts of geothermal and solar generation and 290 megawatts of energy storage capacity. Its customers are typically creditworthy entities that sign long-term contracts to meet their renewable energy mandates. In the Product segment, the company sells equipment to other independent power producers. While the total number of customers is small compared to a consumer business, each contract represents hundreds of millions of dollars in long-term committed revenue.
What gives it staying power?
Ormat's staying power comes from its ownership of rare geothermal resources and its proprietary technology that makes lower-temperature heat economically viable. Geothermal sites are location-specific and difficult to replicate. Because Ormat owns the technology and the land, it has a high barrier to entry that competitors cannot easily cross.
Where is it headed?
Ormat is aggressively shifting toward energy storage to complement its traditional geothermal electricity sales. Management recently brought the 80-megawatt Bottleneck facility online, its largest storage project to date, as part of a strategy to capitalize on grid volatility. If this pivot succeeds, it allows Ormat to capture higher prices during peak demand hours, effectively turning a steady utility into a more dynamic energy trader.
The business is seeing steady growth as new geothermal and storage capacity begins to generate cash. Revenue grew 6.1% in 2024 to $880 million, and analyst estimates suggest this will reach $1.16 billion by 2026. This acceleration is driven by the completion of several major projects that are finally transitioning from construction costs to electricity sales.
Free cash flow is currently negative as the company spends heavily to build its future pipeline. Ormat reported negative free cash flow of $80 million in 2024 and expects a larger deficit of $280 million in 2025. This gap between earnings and cash reflects the capital-intensive nature of drilling geothermal wells and building battery facilities before they can earn a single dollar of revenue.
The company carries a significant debt load to fund its international expansion. Debt-to-equity stands at 1.33x, which is typical for a utility but requires disciplined management of interest costs. Most of this debt is tied to specific power plants, meaning the company uses the steady cash from electricity sales to pay down the loans over decades.
Ormat is a financially stable utility undergoing a massive, debt-funded growth phase that will determine its value for the next decade.
Revenue growth in the Electricity segment is accelerating as 253 megawatts of new capacity were added in 2024 alone. This growth is a mix of organic drilling and strategic acquisitions, proving management can scale the business through multiple channels. The storage business is also scaling rapidly, adding high-margin flexibility to the portfolio.
The heavy capital expenditure required for the 3,400-megawatt pipeline could strain the balance sheet if interest rates remain high. Because geothermal projects take years to build, any delay in reaching "first power" can cause interest payments to eat into the project's eventual returns. Management must execute flawlessly on project timelines to keep the debt manageable.
The geothermal and energy storage market is approximately $60 billion today and is projected to grow ~12% annually as grids demand carbon-free power that does not disappear when the sun sets. Pricing power in this industry is structural because baseload renewable power is far more valuable to a utility than intermittent solar, allowing for premium contract rates. Ormat stands as the only vertically integrated global leader in this niche, giving it a dominant position in the "firm" renewable power market.
The geothermal industry is rationally structured due to the extreme technical difficulty and high upfront cost of drilling, which acts as a natural barrier to entry. Competition is less about price and more about access to rare, high-quality geothermal reservoirs. One mistake in drilling can cost tens of millions, making experience the ultimate defensive asset. Barriers to entry are exceptionally high because few companies possess the technical data and equipment to execute global geothermal projects.
Major competitors like Enel and Berkshire Hathaway Energy have deep pockets but lack Ormat's specific, proprietary "Binary Cycle" technology which allows power generation from lower-temperature fluids. Mitsubishi competes primarily on the equipment side, but Ormat's integrated model allows it to capture the profit of both the manufacturer and the operator. The most dangerous threat is the rising efficiency of long-duration battery storage, which could eventually make solar-plus-storage a cheaper alternative to geothermal.
Ormat is currently holding its ground by aggressively expanding its own storage segment to complement its geothermal base. The company added 253 megawatts of capacity in 2024, maintaining its lead in the niche.
Ormat’s primary protection is its massive library of proprietary intellectual property and "Efficient Scale" in niche geothermal locations. Its binary power systems are the global standard for making energy from lower-heat resources that competitors simply cannot use effectively. This technological moat is reinforced by the fact that once Ormat builds a plant on a geothermal field, it effectively owns that resource for decades.
The company's 27.5% gross margin and consistent project wins prove that its technological edge translates into real pricing power. While the return on invested capital of 2.7% looks low, it is typical for an infrastructure business in a heavy build-out phase and reflects the massive investments currently sitting as "work in progress." These numbers confirm a durable business model where high upfront costs lead to decades of steady, protected cash flow.
The forward-looking verdict is that this moat is strengthening as geothermal becomes a critical "balancing" asset for green grids. The single most important signal is the 3,400-megawatt pipeline, which represents a massive lead in signed future projects.

Capital Allocation Track Record
Doron Blachar has demonstrated high-caliber leadership by successfully pivoting Ormat from a pure geothermal player into a diversified "renewable baseload" provider. He has managed the difficult balance of heavy capital investment and international operational risk without a major blow-up. His decision to aggressively scale the energy storage segment before it became a crowded trade shows a strong strategic vision that has well-positioned the company for the next decade of grid evolution.
The governance risk is relatively low as Ormat operates as a professional, mature corporation with a credible bench of engineering and financial talent. While the company is technically complex, the thesis is not overly dependent on a single founder's personality. The primary risk is the geographic concentration of some international assets, but management has proven for decades that they can navigate these complex regulatory environments across Kenya, Guadeloupe, and Central America.
We expect revenue to grow from $1.2B in FY2026 to $1.8B in FY2031 (~9% CAGR), with EPS growing from $2.32 to $6.41 (~23% CAGR). Revenue growth accelerates as a massive pipeline of energy storage projects and new geothermal plants in emerging markets transition from construction to active power generation. Profit margins expand significantly because the high upfront costs of drilling and plant construction are fixed, allowing new electricity sales to flow down with minimal extra expense. Operating margin expected to reach ~32% by FY2031.
Storage scaling transforms Ormat into a grid-balancing utility. As battery capacity reaches 500MW+, Ormat can sell power at peak pricing, significantly lifting margins compared to fixed-rate geothermal contracts.
New geothermal technology opens up previously unusable thermal sites. Advancements in drilling and heat exchange could expand Ormat's addressable market to regions once thought too cold for geothermal.
Inflation Reduction Act subsidies accelerate US geothermal and storage projects. Federal tax credits effectively lower the capital cost of Ormat's US pipeline, improving the return on invested capital.
Drilling failures or resource depletion at key geothermal fields. A major geothermal field underperforming would force multi-million dollar write-downs and damage the company's core electricity revenue.
Rising interest rates increase the cost of funding massive CapEx. If the cost of debt rises faster than contract prices, the company's leveraged growth model could see earnings compressed.
Battery technology costs fall faster than geothermal drilling costs. If solar-plus-storage becomes significantly cheaper, utilities may choose it over new geothermal plants despite the baseload benefit.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach based on projected FY2027 earnings to determine the fair value. This framework fits Ormat because it is a mature, GAAP-profitable company with predictable long-term power purchase agreements, yet its rapid growth in Energy Storage makes it trade more like a "Renewable Growth" play than a traditional utility. A forward P/E captures the earnings ramp from new capacity without the noise of the massive, lumpy capital expenditures currently suppressing free cash flow.
Our fair value of $122 is calculated by applying a 49x multiple to the FY2027 EPS estimate of $2.49. A 49x multiple sits between high-growth renewable peers like Enphase at 55x and mature renewable operators like NextEra Energy at 25x, which is justified by Ormat’s unique "Wide Moat" geothermal niche and its transition into a critical grid-balancing provider. The $2.49 EPS basis matches the deterministic projection engine's output for the second forward fiscal year.
Cross-checked with a 5-year Discounted Cash Flow (DCF) using an 8.5% discount rate, we get a fair value of $105—within 14% of our P/E-based answer, confirming the result. The DCF produces a lower value because it heavily penalizes Ormat for the significant cash outflows required to build its 3,400MW pipeline. However, for a utility of this quality, we trust the P/E method more as the market typically prices these assets on the stability of their long-term contracts and baseload earnings power rather than near-term construction-cycle cash flows.
We're assuming the Energy Storage segment becomes the primary growth driver with margins stabilizing at 35% by FY2027. This segment recently recorded 140% year-over-year growth; while that pace will naturally decelerate, the integration of solar-plus-storage projects like Arrowleaf provides high-value grid-balancing services that command a premium over traditional intermittent renewables.
We're assuming Electricity segment margins recover to 30% after recent maintenance headwinds. The first quarter of 2026 was hampered by maintenance and a weaker revenue mix, but historical performance and the commissioning of the Topp 2 project support a return to the 30-34% range as utilization rates normalize across the geothermal fleet.
We're assuming the "AI power shortage" narrative sustains a valuation premium for baseload geothermal assets. Unlike wind or solar, Ormat provides 24/7 carbon-free power, which is increasingly valuable to data center operators. This "green baseload" status justifies a P/E multiple significantly higher than traditional regulated utilities.
The biggest risk is the heavy capital expenditure requirement to expand the geothermal pipeline in a "higher-for-longer" interest rate environment. This would strain the company's already negative free cash flow, potentially forcing a multiple compression from 49x to 35x and knocking approximately $35 off the per-share fair value. Watch the quarterly interest expense and "Cash Used in Investing Activities" relative to operating cash flow.
Bear case ($85): Energy Storage gross margins drop below 25% due to increased competition and hardware cost inflation; or Debt-to-equity ratio exceeds 1.8x, signaling high financial risk for upcoming project financing.
Bull case ($165): Product segment revenue growth exceeds 40% annually through 2027 behind strong Indonesian backlog; or Geothermal capacity expansion reaches 2.0 GW by 2028, two years ahead of internal strategic targets.

The market is leaning bullish because geothermal energy provides essential round-the-clock power that intermittent sources like wind and solar cannot match. Utilities pay a premium for this baseload reliability to keep grids stable. With new technology like the Ormega100, the company is scaling its ability to deploy these plants more efficiently across the globe.
Skeptics think that the high price of the stock ignores the slow pace of expansion and the heavy costs of building new power plants. While the technology is unique, the actual growth in generating capacity remains modest and capital intensive, making it difficult to justify current prices based on profit expectations alone.
