Moody’s Ratings estimates that supporting US data centers with 45 gigawatts of new power by 2030 will require $110 billion in energy infrastructure. As electricity demand skyrockets, natural gas is set to become the primary power source. The massive project highlights significant pressure on grid stability and raises questions about how rising electricity costs will be shared between data center operators and consumers.
The rapid expansion of artificial intelligence and cloud computing is forcing a massive upgrade to American energy systems. Moody’s Ratings reports that the US requires a $110 billion capital injection to secure 45 gigawatts of new power capacity by 2030 to keep pace with soaring data center demand. Data centers are expected to double their footprint, consuming 426 terawatt-hours of electricity by the end of the decade, which would account for nearly 10% of total US electricity usage.
The Shift Toward Natural Gas
While the industry is looking at various energy options, natural gas has emerged as the most practical solution for grid reliability. Moody’s projects that over 30 gigawatts of the new supply will come from gas-fired units. Unlike intermittent energy sources such as solar and wind, gas generators offer the consistent, dispatchable load that high-intensity computing requires. Nuclear energy, despite its high capacity, is expected to contribute less than 5% of this new expansion.
Financial and Regulatory Hurdles
This infrastructure drive brings significant economic challenges. The total investment of $110 billion is projected to increase annual electricity costs for US consumers by $25 billion to $30 billion. While data center operators have committed to funding roughly $15 billion through projects located on their own campuses, the responsibility for the remaining costs is less clear. This funding gap is expected to face intense scrutiny in state regulatory processes, where authorities must balance the need for tech infrastructure with the goal of keeping residential power bills affordable.
Risks and Sector Impact
Beyond funding, the timeline for building new power plants remains a concern. Construction delays and complex regulatory environments could slow the delivery of new generation capacity, posing a risk to the 2030 target. For the broader market, this development signals a long-term demand surge for power infrastructure, transmission equipment, and grid management technology. Investors may track how power equipment manufacturers globally respond to this cycle of massive capital spending, as similar trends in grid modernization are often seen in other major economies including India. The central monitorable remains whether the speed of grid expansion can match the pace of AI server deployment without triggering excessive costs for households.
