Switch's Bold Move: Signing a 13MW Geothermal PPA with Ormat Technologies in Nevada – A Game-Changer for Sustainable Data Centers




Welcome back to Alphaxioms Geothermal News, your go-to source for all things geothermal energy, innovation, and sustainability. As we kick off 2026, the intersection of renewable energy and high-tech industries is heating up—literally. Today, we're diving deep into a groundbreaking announcement that's set to reshape how data centers power their operations. Global data center operator Switch has inked a 20-year Power Purchase Agreement (PPA) with Ormat Technologies for 13MW of geothermal power from the Salt Wells geothermal power plant in Nevada. This isn't just another deal; it's a pivotal step toward carbon-free, reliable energy for the AI-driven future.

In this comprehensive blog post, we'll unpack the details of this agreement, explore the technology behind it, discuss its implications for the data center industry, and look at broader trends in geothermal adoption. We'll also touch on challenges, opportunities, and what this means for investors, environmentalists, and tech enthusiasts alike. Buckle up—this is going to be a thorough exploration, clocking in at in words to give you the full picture.

The Deal: What We Know So Far

Let's start with the nuts and bolts. Announced on January 12, 2026, by Data Center Dynamics, Switch—a leader in hyperscale data centers—has committed to purchasing 13MW of geothermal energy from Ormat's Salt Wells facility near Fallon, Nevada. The PPA spans two decades, ensuring long-term stability in an era where energy demands are skyrocketing due to AI and cloud computing.

Power delivery is slated to begin in the first quarter of 2030, giving both parties time to optimize operations. What's particularly exciting is the built-in option for expansion: an on-site 7MW solar farm could serve as auxiliary power, blending geothermal's baseload reliability with solar's peak-hour boosts. This hybrid approach exemplifies smart energy planning in renewable portfolios.

Alise Porto, Switch's SVP of Energy & Sustainability, emphasized the strategic fit: "We are proud to enhance our diverse portfolio of renewable, Nevada-based energy sources and deepen our commitment to powering Switch’s data centers with renewable energy through this new long-term agreement with Ormat." She highlighted geothermal's role in supporting AI workloads, which require uninterrupted, carbon-free power.

On the other side, Ormat's CEO Doron Blachar echoed the enthusiasm: "This agreement not only advances Switch’s sustainability goals but also underscores the growing demand for renewable energy within the data center sector." Ormat, a vertically integrated geothermal powerhouse with a 1.6GW global portfolio, sees this as a revenue booster and a validation of their tech.

This marks Ormat's first PPA with a data center developer, signaling a new market entry for geothermal firms. The Salt Wells plant, a binary-cycle facility operational since 2009, was acquired by Ormat from Enel Green Power in October 2023. Upgrades are underway, aiming for completion by Q2 2026, which will ramp up efficiency and output to meet the 13MW commitment.

Who Are the Players? A Quick Profile

To appreciate the significance, let's profile the key players.

Switch, founded in 2000, operates massive data centers across the US, with a strong footprint in Nevada. Known for their "Switch MOD" modular designs, they've powered clients like eBay, Zappos, and now increasingly AI firms. Sustainability is core to their ethos; they already boast 100% renewable energy usage in some facilities, blending solar, wind, and now geothermal.

Ormat Technologies, headquartered in Reno, Nevada, is a geothermal veteran. With roots in Israel, they've expanded globally, operating plants in the US, Kenya, Turkey, and beyond. Their binary-cycle tech—where hot geothermal fluid heats a secondary fluid to drive turbines—is efficient and low-emission. Ormat's portfolio includes geothermal, solar, and storage, making them a one-stop shop for renewables.

Nevada itself is a geothermal hotspot (pun intended). The state ranks second in the US for geothermal potential, behind only California, thanks to its tectonic activity. Fallon, home to Salt Wells, sits in the Great Basin, where hot springs and faults provide abundant resources.

Geothermal 101: Why It's Perfect for Data Centers

For those new to geothermal, let's break it down. Geothermal energy harnesses heat from the Earth's core—think volcanic activity, hot rocks, and underground reservoirs. Unlike solar or wind, it's baseload power: available 24/7, regardless of weather. This reliability is gold for data centers, which consume massive energy (think 100MW+ per facility) and can't afford downtime.

The Salt Wells plant uses a binary-cycle system. Hot water from wells (around 150-200°C) transfers heat to a low-boiling-point fluid like isobutane, which vaporizes and spins turbines. The geothermal fluid is reinjected, creating a closed loop with zero emissions. Efficiency hovers at 10-15%, but the fuel is free and endless.

Data centers are energy hogs. Global data center electricity use could hit 8% of world demand by 2030, per IEA estimates. AI exacerbates this—training a single model like GPT-4 consumes as much power as 100 US households annually. Traditional grids, reliant on fossil fuels, strain under this load, leading to blackouts and emissions.

Geothermal solves this by providing clean, firm power. It's carbon-free, with a tiny footprint (less land than solar farms), and low water use in binary systems. In Nevada, where water is scarce, this is crucial.

Broader Industry Trends: Geothermal's Rise in Tech

Switch isn't alone. The article mentions Meta's deals with Sage Geosystems and XGS for up to 150MW each, focusing on enhanced geothermal systems (EGS). EGS drills deep into hot dry rock, fracturing it to create reservoirs—think fracking for heat.

Google's in the game too: a 10MW PPA with Baseload Capital in Taiwan and 115MW from Fervo Energy in Nevada via NV Energy. Fervo's innovative horizontal drilling boosts output, aiming for costs under $0.05/kWh.

Why now? Hyperscalers face ESG pressures. Investors demand net-zero commitments, and regulations like the EU's Green Deal mandate sustainable ops. AI's power hunger—Nvidia's GPUs alone could drive 1TW globally by 2030—pushes innovation.

Geothermal's growth is explosive. The US DOE's GeoVision report predicts 60GW by 2050, up from 3.7GW today. Startups like Quaise Energy use millimeter-wave drilling for ultra-deep access, potentially unlocking terawatts.

In data centers, geothermal co-location is emerging. Imagine drilling under a facility for direct heat-to-power conversion, or using waste heat for district heating. Iceland's data centers already leverage this, hosting Bitcoin miners with 99% renewable grids.

Implications for Sustainability and Economics

This PPA is a win for sustainability. Geothermal's capacity factor (90%+) trumps solar (25%) and wind (35%), ensuring steady supply. For Switch, it diversifies from variable renewables, reducing battery storage needs.

Economically, PPAs lock in prices, hedging against volatility. Geothermal LCOE (levelized cost) is $0.06-0.10/kWh, competitive with gas. Ormat's upgrades at Salt Wells—new turbines, better heat exchangers—could drop costs further.

For Nevada, it's jobs and revenue. Geothermal employs skilled workers in drilling, engineering, and maintenance. The state's $1B+ renewable incentives sweeten deals.

Globally, this inspires replication. Kenya, with 1GW geothermal (Ormat operates there), could power African data hubs. Indonesia and the Philippines, geothermal leaders, eye tech partnerships.

 Challenges Ahead: Not All Smooth Sailing

Geothermal isn't without hurdles. Upfront costs are high—$5-10M per MW for exploration and drilling. Risk of dry wells (20-30% failure rate) deters investors.

Permitting is slow; US projects take 5-7 years due to environmental reviews. Seismic risks, though minimal in binary systems, raise concerns post events like Iceland's eruptions.

Water management is key. While binary cycles recycle, some evaporation occurs. In arid Nevada, this matters.

For data centers, latency and location constrain. Facilities need proximity to users and fiber, but geothermal hotspots are remote. Transmission upgrades are needed—Nevada's grid is improving, but bottlenecks persist.

Scalability: 13MW is modest; hyperscalers need gigawatts. EGS promises more, but it's nascent.

Future Outlook: Geothermal's Hyperscale Ambitions

Looking ahead, geothermal could power 10-20% of data center energy by 2040. DOE's $140M in grants accelerates R&D. Companies like Chevron and BP enter via oil expertise.

Hybrid models—like Salt Wells' solar add-on—will dominate. AI-optimized drilling (machine learning predicts reservoirs) cuts risks.

For Switch and Ormat, success could spawn sequels. Switch's Nevada campuses could tap more sites; Ormat's portfolio offers expansion.

Investors: Ormat's stock (ORA) rose 5% post-announcement. Switch, post-2022 DigitalBridge acquisition, eyes IPO.

Environmentally, scaling geothermal cuts CO2 by billions of tons. It's a climate hero, storing no intermittency issues.

Wrapping Up: A Hot Topic for 2026 and Beyond

Switch's 13MW geothermal PPA with Ormat is more than a contract—it's a blueprint for sustainable tech. As AI surges, reliable renewables like geothermal will lead. This deal highlights Nevada's role, Ormat's prowess, and Switch's vision.

EGS Market Size and Investment Outlook

By Robert Buluma Alphaxioms
Enhanced Geothermal Systems (EGS) Market Size and Investment Outlook to 2034 Enhanced Geothermal Systems are at an inflection point. For years, EGS sat in the “promising but pre‑commercial” category of clean technologies, constrained by drilling cost, subsurface risk, and limited policy attention. That picture is now changing as next‑generation geothermal developers raise larger rounds, sign serious offtake agreements, and move projects from concept to execution.   At the same time, global demand for firm, low‑carbon power is rising faster than conventional geothermal can supply. Thermal plants are retiring, grids need 24/7 clean electricity, and policymakers are discovering that weather‑dependent renewables cannot carry the entire load alone. EGS is emerging as one of the few technologies capable of delivering baseload clean power using a resource available almost everywhere: deep, hot rock. Current EGS Market Size – Small but Strategic In absolute terms, the EGS market is s...

GA Drilling: Advanced Geothermal Drilling Technology, Deep Rock Innovation, and Clean Energy Financing

By Robert Buluma Alphaxioms
GA Drilling : Deep Drilling Technology, Financing, and Geothermal Scale-Up Image: A GA Drilling Bit GA Drilling is one of the more important technology companies in the geothermal sector because it is trying to solve a problem that has limited geothermal growth for decades: the cost, complexity, and risk of drilling deep wells in hard rock. Rather than operating a geothermal power plant itself, the company focuses on the drilling side of the value chain, developing technologies that can make deep geothermal wells faster, cheaper, and more reliable to build. That positioning gives it a different role from most geothermal developers, and it also makes it strategically significant for the future of clean baseload energy. The geothermal industry has always been constrained by subsurface uncertainty. Developers know where the heat is in a general sense, but they still must drill through high-temperature, abrasive, fractured, and often unpredictable rock to get there. In many projects, dril...

Tarragona Geothermal Energy Project: Renewable Heating Potential in Six Municipalities

By Robert Buluma Alphaxioms
Hidden geothermal energy under six Tarragona municipalities could power a new phase of the energy transition Image : A Geothermal Power Plant gushing steam to power a grid   A renewable resource beneath the ground A new study in Tarragona has revealed that geothermal energy could become a major local source of heat and cooling for six municipalities: Ascó, Mont-roig del Camp, Montbrió del Camp, Flix, Ulldemolins, and El Perelló . The research suggests that shallow geothermal systems could supply hundreds of buildings and public facilities with a steady, renewable, and locally available energy source . The idea is compelling because it combines climate action with territorial resilience. Instead of depending entirely on imported energy or weather-dependent renewables, these towns could tap into the stable temperature of the subsoil to produce heating, cooling, and domestic hot water . For a region that is already managing the transition away from nuclear dependence, this could ...
