BAAJA Senate Bill Would Make Data Centers Pay Their Grid Costs: Is the $50 Billion Figure Real?

A bipartisan Senate bill would make large data centers pay the grid costs their demand creates. A headline circulating today puts the amount shifted at $50 billion. We could not find that number in any source we checked. What the bill does say is specific and worth understanding, because it targets the question driving data center backlash across the US: who pays for the power lines and plants that AI needs?

This post explains the Bipartisan American Affordability and Jobs Act of 2026, known as BAAJA, what its data center provisions require, where the dollar claims come from, and what happens next.

TL;DR: BAAJA and data centers

What BAAJA is

BAAJA is first a permitting bill. Bisnow describes it as "the most significant permitting reform bill in years," meant to speed up energy assets, power transmission and other large projects. It would set firm deadlines for permit approvals, exempt more projects from lengthy reviews, limit how long approvals can be challenged, and give previously approved projects greater legal protection. It would also change the National Environmental Policy Act, the Clean Water Act and the Endangered Species Act, which is why environmental groups are split on it.

A summary from Mgrid, which cites the Senate Energy and Natural Resources Committee, says four senators control the two committees that write permitting law: Mike Lee chairs Energy and Natural Resources, Martin Heinrich is its ranking member, Shelley Moore Capito chairs Environment and Public Works, and Sheldon Whitehouse is its ranking member. The same summary reports that the bill widens the Federal Energy Regulatory Commission's authority to permit major interstate transmission lines when state regulators stall or reject a project.

For AI readers, the relevant part is the separate set of provisions aimed at data centers.

What the data center provisions say

Bisnow reports that the data center measures apply to facilities larger than 20 megawatts and are "intended to ensure that regular electricity customers don't get stuck with the bill for new power plants and infrastructure for electric transmission built specifically for data centers."

The harder question is what counts as a data center's share. Bisnow explains the gap:

• Tech companies generally accept paying for infrastructure built only for them, such as a substation serving one campus, according to a report by four Democratic senators that Bisnow cites.
• The answer is less clear when new infrastructure also benefits other customers, such as a transmission line built mainly for a new campus that also improves reliability elsewhere.
• Consumer advocates argue for a "but for" test: the data center pays all costs that would not have existed but for its arrival. Developers, per that report, have generally been willing to cover only part of shared costs.

According to Bisnow, BAAJA would take the stricter side: large data centers would pay grid costs that would not have been incurred without their demand, not only upgrades that benefit them exclusively. It would also set more uniform protections across a patchwork of state rules.

The committee's own wording, as quoted by Mgrid, is that the bill "forces data centers to pay their fair share by requiring them to pay for all of their associated transmission costs." A law-firm analysis from Foley Hoag (October 30, 2026) covers the large-load provisions in more detail:

• Two definitions. Section 2107(b), the "ratepayer protection floor," applies to a "covered load" of 20 MW or more. The 20 MW can be reached across several sites under common ownership, and phased projects count if they are expected to reach 20 MW. The FERC transmission pricing language in Section 2107(a) uses a different term, "computational load site," with no size threshold.
• Floor, not cap. For covered loads, utilities could not pass the incremental cost of serving the data center, including new generation, storage, transmission and distribution, to other customers. Regulators could charge more and return the excess to other customers.
• New loads only. The floor applies to loads that interconnect on or after enactment, according to Foley Hoag.
• Timing. FERC would have 270 days after enactment to revise its transmission pricing policy, and a final rule could arrive roughly two and a half years after enactment.
• Reporting. Section 2114 directs the Energy Information Administration to add data center load to its Form 861 survey.

Is the $50 billion figure real?

No source we checked contains it. We looked at the Bisnow reporting, the Senate committee statement as relayed by Mgrid, the Foley Hoag analysis and several other write-ups. None states that BAAJA shifts $50 billion of transmission costs onto data centers. The only $50 billion we found in searches was an unrelated item about an energy pipeline.

The dollar figures that do exist in the coverage we read are these:

Mgrid notes the limits: the study was produced for a group that backs the reforms, and it covers four grid regions rather than the whole country. It also describes the modeled savings as assuming a bill that passes and reforms that hold. None of these figures is a measure of cost shifted to data centers.

So where might $50 billion come from? We do not know. It could be an estimate from an analyst or advocacy group that we could not find, a rounded or mislabeled version of another number, or a headline error. If you have the original source, check what it measures and over what period before repeating it. Until a primary source appears, call it unverified.

Who is for it and who is against it

The sector is divided, according to Bisnow.

Concerns from developers. Harmol Samra, CEO of Host Digital, told Bisnow that "upfront capex, especially speculative, is a death knell," and that added early costs could push smaller operators aside and slow everyone down. His argument is that capital spent before viability is known favors firms with large balance sheets.

Confidence from others. Jeff Thramann, CEO of LT350, told Bisnow that hyperscalers and neoclouds will keep paying higher rents as long as AI demand stays strong, and that pricing already reflects an expectation that developers will contribute to transmission and generation. Tyler Ochs of Ice Miller said the largest players already navigate collateral and financial-guarantee requirements, so for them it is "business as usual," though smaller and regional operators in states without large-load tariffs could be exposed.

Certainty over cost. Both Thramann and Ochs told Bisnow that major developers would accept higher costs for predictable rules.

Environmental groups. The Center for Biological Diversity called the permitting changes a "back-door deal" meant to speed data center development, in comments to Bisnow. Other environmental groups have been more receptive, especially to provisions that speed transmission.

Mgrid adds one more voice of caution: a bipartisan permitting deal came together in 2024 and went nowhere after the election.

What happens next

Mgrid reports the Senate will not vote until after the November midterms, and Bisnow says passage is expected during the lame-duck session after the election. Nothing is law yet. The House would have to pass it too, and the text could change.

The timing links it to the political fight over data centers. Our reporting on the midterm races where data center backlash matters shows candidates running on moratoria and bills. A poll we covered found broad public opposition to data centers. BAAJA is Congress's attempt to answer that concern with a national rule.

How companies are already answering the "who pays" question

Developers are not waiting for a federal law. Several have made voluntary commitments or signed contracts with utilities:

• OpenAI today launched a program to make its future campuses flexible and pay their own costs, starting in Georgia; see our write-up of the OpenAI Grid Protectors Program.
• Google has worked with a power-services company on demand flexibility; see Google and Voltus's 1 GW virtual power plant.
• Regulators are still deciding how much curtailment they can impose; see FERC's rejection of a PJM curtail-first plan.
• Local cost fights continue, as in the De Soto, Kansas household cost argument.

Bisnow also notes the administration's Ratepayer Protection Pledge, announced in March, in which major tech firms committed to cover the full cost of power delivery and grid updates. What counts as "full cost" has been a matter of interpretation, and BAAJA would put a definition into law.

What this means for people who build with or pay for AI

For most API users, nothing changes this week. The long-term effect is on the cost and speed of building capacity.

• Capacity cost. If developers must pay more up front, some of that will show up in rents and, eventually, in the price of compute. Thramann's view is that tenants will absorb it while demand is strong. Samra's is that there is a ceiling on what tenants will pay.
• Who builds. Higher upfront costs favor large developers. That could concentrate AI capacity among fewer, bigger operators.
• Speed. Faster permitting could shorten waits for power in markets where grid connections take years. The two halves of the bill pull in opposite directions: quicker approvals, higher entry costs.
• Rules clarity. A national standard would replace a patchwork of state tariffs. Developers told Bisnow they value that.

What to watch

1. A primary source for the $50 billion number, if one exists.
2. The final bill text and the exact definition of costs data centers must cover.
3. Whether the Senate votes in the lame-duck session and what changes before then.
4. Any House action or a White House statement.
5. How developers change site selection and financing in response.
