Thematic Lens: Baseload Stability, AI Infrastructure Energy Demand, Next-Gen EGS Technologies
Executive Summary
The geothermal energy sector is undergoing rapid expansion, fueled by escalating global electricity demand, projected at +4% annually through 2027. Favorable policy environments, particularly the January 2025 U.S. Executive Orders declaring a national energy emergency aimed at boosting domestic geothermal production, are providing significant growth catalysts. Additional state-level incentives such as Nevada’s generous 55% property tax abatements and California’s stringent mandate for 1GW firm geothermal capacity further enhance the sector’s attractiveness.
Technological advancements, particularly Enhanced Geothermal Systems (EGS) and superhot rock geothermal, promise substantial growth, potentially delivering up to 4.3 terawatts of clean, firm power in the U.S. alone – far exceeding current domestic electricity consumption. Ormat Technologies (NYSE: ORA) remains the clear sector leader, capitalizing on its vertically integrated business model, strong financials ($880 million annual revenue in 2024), and broad geographic diversification. Strong regional competitors, including Green Tech International (BVB: GREEN) in Europe and Contact Energy (NZE: CEN) in New Zealand, also showcase significant operational and financial strengths.
