US electricity demand from data centers is projected to rise 20% over the next decade, increasing interest in geothermal as a scalable power source. Next-gen geothermal is attracting more than $1.5 billion in private capital since 2021, with companies such as Ormat and Sage Geosystems targeting commercial projects by 2027. The article points to improving commercialization prospects for a niche renewable technology with potential grid and data-center power applications.
The market is still underestimating geothermal as a grid-balancing asset rather than just another renewable. The second-order winner is not only the project developer but the firm that can sell firm, dispatchable capacity into a system increasingly penalized for intermittency; that makes geothermal economically more interesting in regions where power prices spike during peak load and where data-center operators will pay a premium for reliability. The capex intensity is the main moat: if drilling and reservoir engineering costs keep falling, the industry can convert a historically niche resource into a repeatable infrastructure product, which should compress perceived project risk over the next 12-24 months. For ORA, the market likely still values it like a steady renewable/IPP, not a platform that could re-rate as a technology-enabled baseload supplier. The equity upside is less about near-term earnings and more about multiple expansion if commercial milestones prove geothermal can scale beyond pilots; that re-rating can happen before full revenue contribution, which matters because infrastructure investors tend to pay up once bankability improves. The main competitive pressure is from nuclear SMRs and long-duration storage: if either advances faster on cost or permitting, geothermal’s “clean firm power” narrative becomes less unique and the trade can stall. The biggest risk is timing slippage, not thesis failure. These projects can look compelling in announcement phase but still take 18-36 months to prove reservoir productivity, financing structure, and utility interconnection, so the stock can underperform if investors expect a 2026-27 revenue step-up that arrives later. A weaker power-price environment would also hurt, because the economics are most attractive when utility and data-center buyers are forced to pay for 24/7 reliability; if gas stays cheap and load growth moderates, the incremental value of firm geothermal narrows. The contrarian point: consensus may be too focused on the supply of capital and not enough on the scarcity of execution talent. That means the real bottleneck is not funding but drilling performance, permitting, and interconnection queues; firms with the best subsurface data and partner ecosystem can capture disproportionate economics while many entrants dilute returns. In that sense, the opportunity is real but likely winner-take-most, which argues for selectivity rather than a broad thematic bet.
