Google warned that power-grid interconnection delays are becoming the primary bottleneck to expanding data center capacity for surging AI workloads, with some US utilities reportedly quoting 4–10 years for new data center connections and, in extreme cases, up to 12 years even to review interconnection requests. The company framed the issue as a transmission and interconnection constraint that is increasingly limiting cloud capacity expansion as data center electricity demand accelerates.
Microsoft, responding to community and regulatory concerns about higher residential electricity rates and local resource impacts tied to large AI data centers, said it will push for utility rate structures that ensure data centers pay the full cost of the electricity and required grid infrastructure upgrades needed to serve them. The company also highlighted efforts to reduce environmental externalities—targeting a 40% improvement in water-use intensity by 2030 and deploying a closed-loop cooling design (already used in Wisconsin and Georgia) intended to eliminate the need for potable water for cooling—underscoring that grid capacity, pricing, and resource constraints are becoming central operational risks for AI-scale infrastructure.

At an AEI event on January 15, 2026, Google's head of global sustainability and climate policy said delays in connecting new loads to the power grid had become the biggest obstacle to expanding data-center capacity. Google said utilities in some regions were quoting 4–10 years for new connections and up to 12 years just to review interconnection requests.
In a Microsoft blog post reported on January 13, 2026, the company said it would ask utilities and regulators to set data-center electricity rates high enough to cover full costs, support rate structures charging very large customers their cost to serve, and avoid seeking local property-tax reductions. Microsoft also said it aims to improve data-center water-use intensity by 40% by 2030 and highlighted closed-loop cooling deployments in Wisconsin and Georgia.
A Lawrence Berkeley National Laboratory study published in December 2025 projected U.S. data-center electricity consumption would grow from 176 TWh in 2023 to 325–580 TWh by 2028, underscoring mounting grid pressure from AI workloads.
