States Block Local Data Center Rules as Cities Push Back

At least 9 states have considered legislation that would limit municipal authority over data centers and AI in the last two years, according to reporting that cites the Local Solutions Support Center (Truthout). The advocacy group and the Truthout report say legislators in New Hampshire, Ohio, South Carolina, and Virginia introduced bills framed as a "right to compute" and that several of those bills re-use model language from the American Legislative Exchange Council, per the Local Solutions Support Center and Truthout.

The Denver City Council voted unanimously to impose a one-year moratorium on new data-center construction inside city limits, Denverite reports; councilmembers cited concerns about community health and the use of large diesel backup generators. City & State Pennsylvania reports that the Pennsylvania House passed House Bill 1834 on a 104-95 vote to task the state Public Utility Commission with drafting temporary and permanent regulations for commercial data centers, including provisions to prevent utilities from passing infrastructure costs onto ratepayers. WRAL reports that North Carolina lawmakers circulated a draft "Ratepayer Protection Act" that would require large data centers to cover electricity and infrastructure costs and set rules on water use and ownership; WRAL attributes the draft to state legislators and a copy from Rep. Pricey Harrison.

Reporting by WTAE and WRAL highlights that the rapid growth of hyperscale data centers is straining local grids and raising utility and ratepayer concerns. City & State Pennsylvania documents that HB 1834 would require commercial data centers to source a growing portion of their energy from clean sources, starting at 10% in 2027 and rising to 32% by 2035, and would place costs for transmission and reliability upgrades on data centers rather than customers, per the bill text and sponsor statements cited in City & State.

Editorial analysis: State-level preemption bills and model legislation are a recurring pattern when industry-facing infrastructure expands quickly across municipal boundaries. Observers tracking preemption note that using model bills can accelerate identical proposals across many state legislatures, which limits local policy experimentation and raises the stakes for state-level regulatory design.

Editorial analysis: For practitioners, the patchwork of moratoria, state rules, and preemption efforts increases uncertainty around site selection, permitting timelines, and grid interconnection cost allocation. Companies and partners working on deployments should expect different permitting and cost-allocation regimes across states and municipalities, and to factor those differences into project risk models.

Editorial analysis: The tug-of-war between municipal controls and state preemption has implications for energy planning, environmental justice, and grid reliability. Localities have used moratoria and zoning to raise questions about air quality, diesel backup generators, water use, and community impacts; state bills focus on uniform rules, ratepayer protections, or limiting local restrictions. That dynamic amplifies the role of state public utility commissions and state legislatures in shaping where and how compute infrastructure connects to the grid.

Editorial analysis: Track three indicators-:

• •final language of bills in statehouses that would preempt local zoning or require statewide permitting
• •public utility commission rules or orders that assign transmission and reliability costs to data centers or to utilities
• •litigation and municipal ordinances that test the boundary between local land-use authority and state preemption. Observers should also watch model-bill sources and lobbying disclosures to see which stakeholders are driving uniform language across states

Editorial analysis: The reporting collected here shows concurrent local and state-level policy activity. Practitioners building or operating data centers, advising public agencies, or modeling grid impacts should expect continued legal and regulatory flux; state-level statutes or PUC rules emerging in the next 12-24 months will materially affect siting economics and compliance requirements.
