Tennessee has enacted legislation that forces data center owners to bear the complete financial burden of all public infrastructure their facilities require, shielding existing utility ratepayers and taxpayers from absorbing those costs.

The bill, HB 1847 / SB 2128, passed the state House by a vote of 76 to 14 and cleared the Senate unanimously, 28 to 0, signaling broad bipartisan recognition that the explosive growth of data center development has begun to strain public infrastructure systems in ways that historically fell on ordinary customers to fund.

What the Law Requires

The legislation amends multiple sections of the Tennessee Code Annotated, specifically covering counties, municipalities, public planning, and utilities, and introduces a brand-new chapter dedicated to data center regulations. Specifically addressing data center infrastructure obligations.

Under that new chapter, the definition of infrastructure is drawn broadly. It encompasses roads, bridges, utilities, cooling systems, and fiber connections, and it captures both capitalized expenses as defined under generally accepted accounting principles and fees imposed by municipalities or utilities.

Any new or expanding data center operating in Tennessee will be required to pay all such infrastructure costs in full.

Developers are expressly prohibited from shifting those costs onto taxpayers, neighboring ratepayers, or other commercial and industrial utility customers. The law takes effect January 1, 2027.

Strict Rules for Electric Utilities

A significant portion of the law addresses how electric utilities must structure their rates in response to the heavy power demands that data centers place on the grid. Utilities are now required to ensure that data centers alone pay for any additional generation, transmission, substation, and distribution upgrades that their load necessitates.

The law prohibits utilities from raising rates on residential customers or other businesses to cover costs that are attributable to data center demand.

To accomplish this separation of costs, utilities are permitted to create a distinct data center customer class if necessary.

Any rate increase that a utility seeks to implement must be accompanied by a publicly posted finding demonstrating that the increase is unrelated to data center demand.

This transparency requirement gives the broader public a mechanism to scrutinize utility pricing decisions and understand how infrastructure costs are being allocated.

Customers who believe they have been improperly burdened with data-center-related costs have a formal avenue for relief.

The law grants aggrieved customers the right to file complaints with the Tennessee Public Utility Commission or, in the case of municipal or cooperative utilities, with the governing board of the relevant utility.

Cost-Sharing Agreements Still Permitted Under Conditions

The legislation does not prohibit local governments and utilities from negotiating cost-sharing agreements with data center developers. However, it imposes a clear condition on any such arrangement: the data center owner must remain the ultimate payer.

The provision ensures that even where negotiated agreements are reached, the financial responsibility cannot be transferred in a way that leaves public entities or existing customers holding the bill.

Fiscal Impact

Fiscal analysts reviewing the legislation estimated that redirecting infrastructure expenditures back onto private data center developers would save taxpayers and existing ratepayers at least ten million dollars statewide over time.

The analysis reflects the scale of infrastructure investment that data centers can require, which includes not only power grid upgrades but also road improvements and utility expansions that communities would otherwise be expected to fund or absorb through rate increases.

Sponsors and Legislative Support

The bill was sponsored in the Senate by Senator Brent Taylor, a Republican, and in the House by Representative Ed Butler, also a Republican. The legislation carried substantial co-sponsorship on both sides of the chamber.

Four House Republicans co-sponsored the bill: Jody Barrett, Michele Reneau, Dan Howell, and David Hawk.

Nine Senate Republicans added their names as co-sponsors: Page Walley, Ken Yager, Paul Bailey, Janice Bowling, Rusty Crowe, Todd Gardenhire, Adam Lowe, Bill Powers, and John Stevens.

The Tennessee Legislative Report Card, which tracked and analyzed the bill, listed its position as support. The organization's statement characterized the measure as ensuring that data center developers cannot externalize their infrastructure costs onto the public, describing the law as a straightforward mechanism for holding private beneficiaries financially accountable for the public systems their operations depend upon.

Context Within Tennessee's Data Center Growth

Tennessee has seen increased interest from data center developers drawn by factors including available land, energy infrastructure, and economic incentives.

That growth has accelerated questions about who should pay for the substantial upgrades to roads, power grids, and utility systems that large-scale computing facilities demand.

The passage of this legislation places Tennessee among states that have moved to formally answer that question by codifying in law that private developers, not the public, bear those costs.
