AI infrastructure is rewriting the energy playbook.
In this episode of the Data Center Frontier Show, Sage Geosystems CEO Cindy Taff joins DCF Editor-in-Chief Matt Vincent to discuss how the explosive growth of AI has shifted data center priorities from long-term decarbonization goals toward the immediate challenge of securing enough power, quickly and in the right location.
Taff explains why aggregate generation capacity means little if electricity cannot reach a data center when it is needed. With transmission constraints and grid interconnection timelines stretching for years, hyperscalers and developers are increasingly exploring behind-the-meter generation and participating directly in energy infrastructure development.
The conversation examines Sage Geosystems’ next-generation geothermal technology, which targets hot dry rock rather than the naturally occurring underground water resources required by conventional geothermal projects. By engineering subsurface reservoirs, Sage aims to make firm, dispatchable geothermal power available across a much wider geographic footprint.
Taff also discusses how Sage combines geothermal generation with energy storage and pressure management, while addressing the water losses and high operating energy requirements associated with traditional enhanced geothermal systems.
The episode explores geothermal’s evolution from a primarily “green” energy resource into strategic infrastructure for AI. Unlike intermittent renewables, geothermal can provide firm, 24/7 power and potentially be developed close to major loads.
Taff argues that the oil and gas industry’s drilling expertise and existing infrastructure could provide a powerful scaling advantage. A hypothetical 5-gigawatt geothermal buildout over five years would require roughly 500 wells annually—a small fraction of current U.S. oil and gas drilling activity.
The central takeaway: gigawatt-scale AI campuses may dominate the headlines, but they will still be built 50 to 100 megawatts at a time.
For the next generation of data center development, Taff says the industry’s most important metric is becoming clear: time to power now matters more than cost or total capacity.
