Geothermal power has reached a pricing milestone, with average costs of $105.56 per megawatt-hour in NV Energy’s 2026 resource plan, undercutting competing solar-plus-storage proposals by roughly 7%.
The result marks a significant turning point for an energy source that has long struggled to compete economically against the rapidly falling costs of solar and battery storage combinations.
NV Energy’s 2026 integrated resource plan provides one of the clearest apples-to-apples comparisons yet between geothermal and solar-plus-storage, giving the industry concrete data to work with.
The pricing edge geothermal now holds reflects a combination of federal tax credits, technological advances, and a surge in demand from data centers hungry for reliable, around-the-clock clean power.
Unlike solar and wind, geothermal delivers firm, baseload generation regardless of weather conditions, a characteristic that has become increasingly attractive to grid planners dealing with reliability pressures.
Data centers, which require constant and dependable power supplies, have emerged as a major driver of renewed interest in geothermal, pushing developers to accelerate project pipelines across the western United States.
Federal tax incentives introduced in recent years have meaningfully reduced the cost of bringing new geothermal capacity online, narrowing the gap with more established renewable technologies.
Technological progress, particularly in enhanced geothermal systems that allow developers to tap heat resources in areas previously considered unviable, has expanded the geographic footprint of potential projects.
Despite the improving economics on a per-megawatt-hour basis, shares of major publicly traded geothermal developers have suffered significant losses, suggesting investors remain cautious about the sector’s near-term execution risks.
The disconnect between geothermal’s strengthening competitive position and its weak stock performance may reflect concerns around project development timelines, permitting challenges, and the capital intensity of bringing new plants online.
For grid operators and utilities, however, the NV Energy data represents a compelling case that geothermal deserves a larger role in long-term resource planning alongside solar and storage assets.
Whether geothermal can translate this pricing competitiveness into a sustained wave of new capacity additions will depend heavily on financing conditions, regulatory support, and the continued expansion of enhanced geothermal technology.
