Moody’s Estimates $110 Billion in New US Generation May Be Needed for Data-Center Demand

Moody’s estimates that approximately $110 billion of investment in new generating capacity may be required to serve additional electricity demand from US data centers. It forecasts that annual electricity consumption by US data centers could reach 426 TWh by 2030.

The assessment comes as AI data-center construction accelerates while generation and grid infrastructure development trails behind. Some power projects face delays of up to seven years, creating a potential mismatch between the delivery of data-center campuses and the availability of the generation, interconnection and transmission capacity needed to operate them.

Adding generation alone may not resolve constraints in areas with concentrated data-center demand. Grid expansion and transmission infrastructure are also required to deliver power to those locations. In some regions, new data-center projects have reportedly been paused while regulations are reviewed, although the source does not identify the affected regions or the number of projects involved.

Saskatchewan has also required large data-center operators to maintain their own ability to supply power. Together, these developments suggest that operators and developers may increasingly compete for available interconnection capacity, local generation and network infrastructure, alongside compute equipment. This could lengthen timelines for individual projects, increase energy-related capital requirements and raise the strategic value of sites with confirmed power availability.
