Committee bills

Drafts with committee backing

Bills an interim committee voted to carry into the session. These usually get an early hearing.

No LC yet high ETIC committee bill: large-load customers and ratepayer protection Approved by ETIC for 2027 · Sep 9, 2026 Requester Energy and Technology Interim Committee (Chair Sen. Daniel Zolnikov, R-Billings) Committee bill

Directs the PSC on how a utility serves new retail customers of 5 MW or more: confirm new service won't harm other customers, create a separate large-load customer class, set terms that block cost shifting onto other customers, and require financial guarantees in case a large customer shuts down. Does not cover data centers that build their own power supply.

Why it matters: Unanimous voice vote; Rep. Bob Carter (D-Missoula) made the motion. Zolnikov said the draft still needs work. NorthWestern Energy objected to the no-cost-shift language; MEIC and the Large Customer Group (refineries, cement) back it. Watch for the LC number and amendments before introduction.

Bill draft requests

Requests from individual legislators

Most carry placeholder titles like "generally revise data center laws" until text is drafted. The real content often stays unknown until introduction.

LC 20 high Generally revise law relating to data centers (statewide ban on large-scale data centers) Drafter assigned (Griffin Burns, ETIC staff) · Sep 8, 2026 Requester Sen. Ellie Boldman (D-Missoula) Senate

Placeholder title. In an August 2026 op-ed, Boldman said her first 2027 bill draft request is a statewide ban on large-scale data centers and that she is not interested in compromise.

Why it matters: The most restrictive proposal on the board. Unlikely to pass a Republican Legislature as written, but it frames the debate and could draw moratorium amendments.

  • Siting & bans
LC 251 high Protect ratepayers and provide fiscal protection from data centers Drafter assigned (Griffin Burns) · Sep 16, 2026 Requester Rep. Bob Carter (D-Missoula), ETIC member House

No text yet. Title points to cost-allocation and financial-assurance protections, likely overlapping the ETIC committee bill.

Why it matters: Carter moved the ETIC bill forward; this may be a companion or a stronger Democratic alternative. Compare against the committee draft once text appears.

  • Ratepayers
  • PSC & utilities
No LC yet high Prohibit data centers in areas that use tax increment financing Requested Requester Sen. Wylie Galt (R-Martinsdale) Senate

Would bar data centers from TIF districts, cutting off a local incentive tool that pairs with the 0.9% class 17 tax rate.

Why it matters: A Republican-sponsored restriction, so it has a realistic path. Galt is a senior tax-policy voice. (His separate LC 350 and LC 351 are water-law placeholders, on hold since Oct 1.)

  • Taxation
  • Siting & bans
No LC yet medium Revise data center development laws Requested Requester Rep. Bob Carter (D-Missoula) (inferred from request list; confirm) House

Appears on the 2027 request list just before Carter's ratepayer request. No LC number or text found yet.

Why it matters: Could address siting, development standards or the 2025 tax incentives. Requester attribution needs confirming at the next check.

  • Siting & bans
No LC yet medium Generally revise laws relating to data centers (second request) Requested Requester Sen. Ellie Boldman (D-Missoula) Senate

A second data center placeholder on Boldman's list, separate from LC 20. Boldman also requested a Public Service Commission bill.

Why it matters: May be a fallback (moratorium, reporting or water limits) if the outright ban stalls.

  • Siting & bans
No LC yet medium Revise property taxation of data centers Requested Requester Sen. Dave Fern (D-Whitefish) Senate

Targets the class 17 data center property tax rate (0.9%), which HB 424 (2025) extended to 2037 and to on-site generation.

Why it matters: Fern filed a similar draft for 2025 (LC 1870) that died in drafting. Watch for a rate increase or clawback provisions.

  • Taxation
No LC yet medium Generally revise data center laws Requested Requester Sen. Dave Fern (D-Whitefish) Senate

Placeholder; content unknown.

Why it matters: Second Fern request, separate from his tax bill.

  • Siting & bans
No LC yet medium Generally revise data center laws (two requests) Requested Requester Sen. Laura Smith (D-Helena) Senate

Two data center placeholders (#29 and #30 on her list), alongside a PSC request (#38) and three technology-law requests.

Why it matters: Content unknown; Smith also files consumer-protection bills, so expect a disclosure or ratepayer angle.

  • PSC & utilities
No LC yet low Public Service Commission law revisions Requested Requester Sen. Ellie Boldman; Sen. Laura Smith Senate

Generic PSC placeholders. The governor's Energy Task Force also discussed PSC reform.

Why it matters: Any change to PSC authority or structure changes who decides large-load contracts.

Laws and proceedings

Current law and decisions outside the Capitol

Statutes likely to be amended, plus PSC and executive branch decisions that will shape what the bills say.

SB 212 (2025) high Right to Compute Act: likely amendment target Amendment requested by Yellowstone County · Sep 23, 2026 Requester Sen. Daniel Zolnikov (original sponsor) Law since Apr 16, 2025

Requires any government restriction on computational resources to be narrowly tailored and the least restrictive option. Yellowstone County commissioners say it limits their ability to regulate the 5,000-acre Quantica data center near Broadview and asked their legislators to clarify that local zoning and permitting still apply.

Why it matters: No bill draft request found yet. Watch for a local-control amendment from the Yellowstone County delegation, and resistance from Zolnikov, who chairs ETIC.

  • Siting & bans
PSC docket high NorthWestern Energy Large New Load Tariff (PSC) Pending before PSC · Mar 31, 2026 Requester NorthWestern Energy; DEQ and MEIC-led coalition intervening Public Service Commission

Proposed rules for serving new loads of 5 MW or more: minimum service terms, demand billing, collateral and termination costs, with PSC review of individual agreements only for the largest customers. Gov. Gianforte directed DEQ to intervene in June 2026.

Why it matters: Lawmakers are writing the ETIC bill partly in response. A PSC decision before or during session could make parts of the bill moot or push lawmakers to override it.

  • Ratepayers
  • PSC & utilities
HB 424 (2025) medium Class 17 data center property tax Current law · May 13, 2025 Requester Rep. Katie Zolnikov (original sponsor) Law since May 13, 2025

Keeps the 0.9% property tax rate for data centers, extends the build deadline from 2027 to 2037, and extends the low rate to on-site generation for 10 years. School equalization mills still apply inside TIF districts.

Why it matters: The baseline that the Fern and Galt tax requests would change.

  • Taxation
Gov. task force medium Governor's Energy Task Force recommendations Second report due January 2027 Requester Gov. Greg Gianforte (chair: DEQ Director Sonja Nowakowski) Executive branch

Recommendations released in September 2026 include revising regulations and taxes to encourage energy production and transmission. Members include NorthWestern, Talen and Sabey Data Centers.

Why it matters: Recommendations often become administration-backed bills, usually with agency-requested LC numbers. Watch for large-load, PSC reform and generation bills.

  • PSC & utilities
HB 877 (2025) low Montana Data Center Development Act (failed 2025) Tabled in committee, 2025 · Mar 31, 2025 Requester Rep. John Fitzpatrick (R-Anaconda) House

Would have limited the PSC's ability to block a utility from serving large customers and funded state data center marketing.

Why it matters: Legislative staff flagged it as a possible 2027 revival. Watch for a pro-development counterweight to the ratepayer bills.

Update log

What changed at each check

Tracker created. Baseline of 15 items: one ETIC committee bill, nine legislator requests, five laws and proceedings.

  • ETIC approved its large-load ratepayer protection draft on Sept 9 (no LC number found yet).
  • LC 20 (Boldman, statewide ban) and LC 251 (Carter, ratepayer protection) have drafters assigned.
  • Yellowstone County asked legislators on Sept 23 to amend the Right to Compute Act.
  • The House side of the official request list could not be fully read; Carter's 'revise data center development laws' attribution needs confirming.

Status reflects public sources as of the last check: the Legislature's bill draft request list and LAWS system, interim committee materials, and Montana news coverage. Confirm anything time-sensitive at bills.legmt.gov.
