NH’s proximity to the ISO-NE grid and existing infrastructure like [[Seabrook Station]] (a nuclear power plant) could support data center power needs, especially for AI and HPC workloads that require reliable, high-capacity electricity. STACK’s focus on renewable energy integration aligns with NH’s legislative initiatives, such as HB 710, which encourages clean energy development, though this bill does not specifically target data centers. STACK’s technology is already operational and ready for deployment, which matches NH’s potential timeline for new infrastructure projects. Applications in NH could include powering data centers to support regional cloud services or industrial compute loads, particularly if grid constraints in other Northeast markets push development into less saturated areas like NH. However, challenges include NH’s limited existing data center ecosystem and potential community resistance to large-scale facilities due to power and environmental concerns. No direct NH connections are evident in current data, but STACK’s Northeast US operations (e.g., Northern Virginia) suggest scalability into nearby markets if demand arises. ### Competitive Position STACK Infrastructure competes with major data center operators like Digital Realty Trust, [[Equinix]], and CyrusOne, all of which target hyperscale and enterprise clients. Compared to Digital Realty Trust, STACK benefits from a more focused portfolio post-carve-out, allowing agility in targeting AI-specific workloads with high-density designs. [[Equinix]], with its emphasis on interconnection services, poses a challenge in markets where low-latency networking is prioritized over raw compute power. CyrusOne offers similar hyperscale solutions but may lag in sustainability commitments compared to STACK’s $6 billion green financing milestone. A key risk for STACK is the broader industry challenge of grid capacity, as highlighted in recent X posts, where power shortages could delay projects or increase costs [X sentiment]. ### Closing Note STACK Infrastructure is a well-established leader in the data center industry, with a strong trajectory of growth driven by AI and hyperscale demand and a promising outlook supported by significant sustainable financing. *Report generated December 24, 2025*
