U.S. utilities are confronting a wave of large-load interconnection requests — data centers, hydrogen plants, and battery factories — with planners forecasting roughly 90 gigawatts of data center peak demand growth by 2030. The central risk is not technical but financial: dedicated substations, transmission ties, and distribution upgrades built for a single customer can cost hundreds of millions of dollars, and standard tariffs were never designed to recover those costs without spreading them across all ratepayers.
The scale of the shift is reshaping utility planning in ways that go beyond simple load growth. A hyperscale data center drawing 300 megawatts around the clock has a load profile, credit profile, and timeline that differ fundamentally from traditional industrial customers. When that infrastructure is socialized into the general rate base, residential and small commercial customers effectively subsidize the hyperscaler’s margins. Regulators in multiple states have begun requiring minimum-bill provisions and explicit cost-allocation studies as a condition of approval, signaling that the era of implicit cross-subsidies is closing.
The safeguards gaining traction — contributions in aid of construction, direct facilities charges, dedicated infrastructure riders, take-or-pay floors, and upfront credit assurance — are not punitive measures. They are cost-recovery tools that align the customer paying for the asset with the customer benefiting from it. A defensible cost-of-service study becomes the anchor: without it, negotiations drift into political territory rather than engineering economics. Exit fees and decommissioning provisions add a further layer, ensuring that if a facility idles or departs, the stranded asset burden does not fall on the remaining membership.
For cooperatives and municipal utilities with thinner equity cushions, the stakes are especially high. A single large-load misstep can impair credit metrics and constrain capital for system-wide reliability investments. The contract framework is effectively a risk-allocation document, and the utilities that treat it as a strategic asset — rather than a paperwork exercise — will be the ones that absorb this growth without fracturing their cost structure.
