Senate Bill Could Accelerate Data Center Transmission Reviews and Change Cost Allocation

Introduced in late September 2026, the Bipartisan American Affordability and Jobs Act (BAAJA) is a 400-plus-page bill with potential implications for federal environmental review, transmission development, and data center project economics. A Senate vote could occur as soon as the week of November 9, 2026, although passage is uncertain. The U.S. Senate bill was introduced by Shelley Moore Capito (R-WV), Sheldon Whitehouse (D-RI), Mike Lee (R-UT), and Martin Heinrich (D-NM). The Bipartisan Policy Center said the White House has been involved and wants the legislation to advance while Republicans control both chambers; the source reports that President Donald Trump plans to sign it before year-end if it passes. These developments are not enacted requirements, and contractors should treat the provisions as prospective until legislative action is complete.

BAAJA would make procedural changes to the National Environmental Policy Act (NEPA), which requires federal agencies to consider environmental impacts associated with actions such as permitting, leasing, federal funding, and federal projects. The Bipartisan Policy Center described the bill as revising the statute’s procedures around the “scope of review,” which projects are reviewed, and how long reviews take. The source also says the bill seeks to simplify approval and development of high-voltage transmission corridors and addresses provisions of the National Historic Preservation Act, a process that can add years before construction begins. For contractors, any reduction in review timelines could affect project sequencing, bid assumptions, and the timing of demand for permitting, environmental analysis, engineering, construction, and energy services. The practical effects would depend on the final statutory language and implementation.

The bill’s proposed cost-allocation rule is especially relevant to data center developers and their supply chains. Operators of data centers with capacity of 20 MW or more would be required to cover additional expenses associated with their facilities rather than pass those costs to other customers. The Bipartisan Policy Center said the provisions aim to “build transmission faster while giving states and consumers a stronger voice in how lines, especially those triggered by data centers, are approved and paid for.” Developers and contractors should therefore evaluate how project-specific transmission costs could affect commercial models, site selection, power agreements, and project economics—but should not treat the proposed requirement as current law. The bill also contemplates a more detailed federal picture of electricity demand: the U.S. Energy Information Administration (EIA) would update Form 861 to separately track data-center electricity use for AI, cloud computing, and cryptocurrency mining.

The policy debate is unfolding amid heightened public attention to data center development. The source reports that an Associated Press poll found 56% of surveyed voters considered data centers a “crucial or major” factor in their midterm election vote. Christy Goldfuss, executive director of the Natural Resources Defense Council, criticized the legislation, saying communities could be left out of consequential decisions involving environmental review and infrastructure. That criticism underscores the possibility that permitting changes, community engagement, and cost allocation will remain points of scrutiny. For GovCon firms, the immediate opportunity is to monitor Senate action and prepare scenario-based assessments: identify projects dependent on federal reviews, test cost assumptions for facilities at or above 20 MW, and review the ability to document electricity consumption by workload if the EIA reporting change is enacted.

• Legislative status: BAAJA was introduced in late September 2026; a Senate vote could occur as soon as the week of November 9, but passage is not certain.
• Potential review changes: The bill would revise NEPA procedures concerning review scope, which projects undergo review, and review timelines.
• Transmission focus: Proposed provisions seek to simplify approval and development of high-voltage transmission corridors supporting data center infrastructure.
• Historic preservation: The legislation addresses the National Historic Preservation Act, which the source says can add years to project timelines before construction.
• 20 MW threshold: Data center operators with capacity of 20 MW or more would have to cover additional expenses rather than pass them to other customers, if the bill is enacted.
• EIA reporting: The EIA would update Form 861 to distinguish data-center electricity use for AI, cloud computing, and cryptocurrency mining.
• Contractor implications: Firms supporting permitting, environmental review, engineering, construction, transmission, and energy services should assess how faster reviews could affect schedules and demand.
• Commercial planning: Developers and contractors should model potential transmission cost allocation for projects at or above 20 MW without assuming the proposed rule is already in force.
• Public scrutiny: The source cites an AP poll in which 56% of surveyed voters said data centers were a “crucial or major” factor in their midterm vote; community concerns may remain central to project approvals.
• Near-term action: Track Senate consideration, identify projects exposed to the proposed changes, and assess data and documentation practices for electricity use by workload.
