Geothermal Energy Beats Solar-Plus-Storage on Cost in Nevada
New economic data from Nevada’s power sector reveals that geothermal energy has become a cost-competitive alternative to solar energy combined with battery storage. According to NV Energy’s latest 2026 resource plan, geothermal power offers prices approximately 7% below those proposed for solar-plus-storage projects.
Geothermal’s Improved Cost Advantage
The utility’s filings show three geothermal projects averaging $105.56 per megawatt-hour (MWh), compared to the roughly $113.89/MWh weighted average for eleven solar-plus-storage developments. This marks a significant shift in the renewable energy landscape, where geothermal has historically lagged behind intermittent sources like solar in pricing but offered a more reliable power supply.
The cost competitiveness stems partly from rising solar costs due to factors such as permitting delays, increased financing expenses, land-related costs, and tariffs. For example, the levelized price for Boulder Solar III surged from $85/MWh to $125/MWh between 2024 and 2026, reflecting these challenges.
Firm Power and Growing Demand
Unlike solar projects, which typically pair photovoltaic generation with short-duration batteries (around four hours), geothermal plants provide constant, 24/7 power by tapping heat from underground reservoirs. This continuous output is highly valued by industries requiring dependable energy streams, such as data centers operated by technology giants.
Tech companies are increasingly turning to geothermal for its reliability and sustainability. Google supports up to 150 MW of geothermal power through Ormat’s projects, while Amazon has committed to 100 MW from Zanskar Energy. As Joel Edwards, Zanskar’s co-founder and CTO, recently stated, this moment signals a major turning point, calling it “the flippening” in geothermal energy’s competitiveness.
Why This Matters for Pakistan
Pakistan’s ongoing energy challenges, highlighted by frequent outages and dependency on imported fuels, underscore the urgent need to diversify sources. Geothermal energy, with its ability to provide uninterrupted electricity at competitive prices, could offer a sustainable and reliable solution for the country’s expanding power needs.
Given Pakistan’s geological potential and growing data center industry, the commercial viability of geothermal could encourage investment in local projects. Moreover, reducing reliance on variable renewables plus storage can help stabilize the power grid and lower overall generation costs in the long term.
As global technological advances and supportive policies drive down geothermal costs, Pakistan stands to benefit by integrating this resource into its energy mix, enhancing energy security and supporting economic growth.
