US AI Data Centers to Drive $110B Gas Power Buildout by 2030

Key points

• Moody's Ratings estimates the US needs $110 billion to build 45 GW of new power capacity by 2030 to support AI data centers.
• Natural gas-fired units will provide more than 30 GW of this new supply, representing about 4 billion cubic feet of incremental gas demand.
• Data centers are projected to consume 426 terawatt-hours in 2030, doubling their share of US electricity usage to 10 percent.
• The buildout could add $25 billion to $30 billion annually to US electricity costs, with data centers directly paying for up to $15 billion of these costs.
• Regulatory delays and grid capacity constraints are slowing the pace of data center development, as federal and state regulators review rate structures.

Background

The US has been rapidly expanding natural gas power to feed data centers, with 189 GW announced or under construction as of mid-2026. This surge in gas-powered projects has raised concerns about climate impacts and long-term infrastructure lock-in, even as renewables and storage scale. Additionally, Texas has moved to enforce water-use reporting for data centers, reflecting growing local opposition to their environmental and resource impacts.

How outlets are covering it

Moody's Ratings emphasizes the scale of the power buildout and its cost implications, while The Straits Times highlights the environmental and consumer cost concerns. The Register focuses on the broader AI power demand and the potential for older industries to be cannibalized to meet this demand. All sources agree on the rapid expansion of gas-powered infrastructure but differ in their emphasis on the economic, environmental, and regulatory challenges.

Why it matters

The massive expansion of AI data centers is reshaping US energy infrastructure, driving significant investment in natural gas power and raising concerns about rising electricity costs, environmental impacts, and regulatory delays. This shift could have long-term implications for energy policy, consumer costs, and the transition to renewable energy.

What to watch

Regulators will continue to review rate structures and grid capacity constraints, potentially delaying data center developments. The pace of gas power expansion may accelerate, but opposition from local communities and environmental concerns could slow progress. The long-term impact on electricity costs and the energy mix will depend on how costs are allocated and how quickly renewable energy and storage can scale.
