GridCARE develops the Energize platform, which uses physics-based AI models to evaluate grid conditions—congestion, outages, weather, and demand fluctuations—in real time to locate underutilized power capacity. The company positions this approach as a way to shorten interconnection timelines for large data centers and AI facilities from years to months by unlocking existing grid capacity. GridCARE reports active projects across more than a dozen markets representing over 2 gigawatts of prospective AI compute capacity and cites a Portland General Electric collaboration that identified a pathway to unlock more than 400 megawatts with 80 megawatts expected online in 2026. Co-founder and CTO Ram Rajagopal is a Stanford professor on leave, and the company emphasizes working collaboratively with utilities. GridCARE frames the market opportunity around a “Time-to-Energize Crisis,” arguing power availability is a growing bottleneck for AI expansion. Financially, the company recently raised a $64 million Series A in an oversubscribed round that materially increased its valuation versus a round less than a year earlier.

Zanskar combines artificial intelligence, modern drilling techniques, and computational geoscience to find, assess, and develop geothermal energy resources. The company has a portfolio of greenfield geothermal projects, including the Lightning Dock site in New Mexico and recent discoveries at Pumpernickel and Big Blind in Nevada, plus two announced discovery sites in Nevada. Financially, Zanskar completed a $115 million Series C in January 2026 (later expanded with additional investment from Just Climate) and has now closed a $40 million revolving Development Capital Facility structured to scale to $100 million. Zanskar plans to use the new facility to fund pre-construction work and bridge projects to traditional project financing so it can rapidly build multiple geothermal power plants. The company aims to deliver gigawatts of clean, firm power to U.S. customers and expects to create hundreds of jobs as it scales development. Zanskar markets its approach as making geothermal more predictable, lowering development costs, and enabling large-scale deployment of dispatchable baseload power.
