The House just voted 417-3 to make data centers post a bond before the grid work starts

The U.S. House voted 417-3 on September 16 to make data center developers — not the power company's other customers — pay for the grid upgrades their campuses require. If it becomes law, it adds a financing milestone to every data-center project's schedule that didn't clearly exist before: prove you can pay for the substation and transmission work before the utility builds it.

What does the bill actually require?

H.R. 9340, the Ratepayer Protection Act, pushes state utility regulators to adopt a standard holding "large-load customers" — non-residential users with 100 MW or more of peak demand at one site, the size of a hyperscale data center — responsible for the full, incremental cost of any generation, transmission, or distribution upgrade needed to serve them. It also directs FERC to write rules on large-load interconnection covering cost allocation, financial security requirements, and cost-estimate disclosure. The bill cleared the House with only three no votes and now moves to the Senate, which has two competing versions of its own (a 50 MW threshold in one bill, 150 MW in another).

What's the financial assurance piece, specifically?

This is the part that changes a project schedule, not just a utility bill. Under the bill, a data center operator has to post financial assurance before a utility starts building the grid infrastructure to serve it — and stays liable for those costs even if the project is later canceled, downsized, or the operator exits its power contract early. Today, some of that risk has landed on utilities and, by extension, other ratepayers when a data-center deal falls through after infrastructure work has started.

Why does this matter to a GC or precon team chasing data center work?

Two effects, both worth tracking if your firm bids the utility-side scope on these campuses (substations, on-site switchgear, transmission tie-ins) or the vertical building work that follows it:

1. A new gate before grid work can start. If your firm is pricing or scheduling the electrical infrastructure package tied to a campus, the utility may not issue notice to proceed on that scope until the developer's financial assurance is posted — a checkpoint worth confirming with the owner's team before you commit precon staff or long-lead procurement to a project.
2. A cleaner signal on which announcements are real. The construction industry has spent 2026 chasing a wave of data-center announcements that don't all reach groundbreaking. A developer able to post financial assurance for grid costs upfront has already cleared a financing bar that a purely speculative land deal hasn't. Estimators building a pursuit list can use "has this project posted financial assurance" as a screening question the same way they'd ask about a signed GMP or a permitted site.

Should a mid-size GC change its pursuit strategy now?

Not yet — the bill hasn't passed the Senate, and even if it does, state utility commissions get up to two years to implement any resulting standard. But the direction is bipartisan and nearly unanimous in the House, and it lines up with what FERC has already told grid operators this year: stop letting data-center transmission costs land on other customers. Build the financial-assurance question into how you qualify data-center leads now, so it's not a surprise when a state adopts the standard and a project you're tracking suddenly needs a bond posted before the substation work you priced can start.

The takeaway: the money behind a data-center campus is about to get more visible, earlier. Ask about grid-cost financial assurance the same way you'd ask about a site's power availability — before you spend precon hours on a deal that hasn't cleared it.
