SB 505 would amend Montana's zoning laws to allow local governments to prohibit the construction of wind energy facilities by preventing utility companies from connecting power from these projects. Specifically, it targets subsection (28) of Section 7-1-111, which would permit local governments to block utility connections for wind generation facilities defined under state law. This bill directly affects wind energy developers and local planning authorities, as it removes a key barrier to project development. The policy change focuses on utility interconnection as the mechanism for restricting wind facility construction, rather than general zoning rules. The bill did not become law, as it died in committee in 2025.
SB 283 would establish new height and lighting rules for wind energy projects in Montana. It requires all new wind turbine towers built after January 1, 2026, to not exceed 350 feet in height (measured from ground to turbine hub center), and mandates federal aviation-approved aircraft detection lighting systems on towers over 200 feet tall. These rules apply to new wind generation facilities (defined as projects with 25+ megawatt capacity) but do not affect existing towers built before 2026. The bill also provides definitions for key terms like "wind generation facility" and "turbine rotor hub" to clarify the regulations. The proposed changes would directly impact developers and operators planning new wind energy projects in Montana.
SB 160 requires owners of qualifying wind and solar energy facilities in Montana (solar: 2+ megawatts, wind: 25+ megawatts) to provide a decommissioning bond before construction begins. The bond amount, determined by the Department of Environmental Quality based on the owner's decommissioning plan, ensures funds are available to dismantle facilities and restore land within 24 months after a facility's end of life or abandonment. This applies to new projects and modifies existing requirements for facility owners to submit plans and bonds prior to commercial operation.
SB 81 authorizes Montana's state board to lease public lands for underground storage of natural gas or liquefied gas (including carbon dioxide and methane), primarily affecting natural gas utilities operating in Montana. Key provisions include requiring lessees to pay for remaining natural gas deposits in the land, limiting bonds to $20,000 per lease, and mandating lease terms to prevent waste or damage to gas deposits. The bill also grants the state board rulemaking authority over these leases and forfeiture procedures for violations. This legislation failed to pass, dying in committee after its third reading failed in March 2025.
Senate Bill 333 repeals the termination date for the existing coal severance tax coal washing credit. This credit, previously set to expire on July 1, 2027, will now continue indefinitely. The bill directly affects coal mining companies and processors that utilize coal washing and are subject to the coal severance tax, allowing them to continue claiming this tax credit.
HB 703 exempts specific state and local agencies in Montana from analyzing greenhouse gas emissions during certain environmental reviews. The bill states that the state department and local building departments are no longer required to analyze greenhouse gas emissions from covered appliances when adopting or enforcing building codes. It also exempts the state department from analyzing greenhouse gas emissions from new motor vehicles, engines, and nonroad vehicles, and emissions originating outside the state's borders. The bill cites federal preemption laws as the basis for these exemptions from environmental review.
House Joint Resolution 17 is a resolution from the Montana Legislature urging the U.S. Congress and President to take actions to promote American energy production. It calls for reforming and streamlining federal permitting obligations and revising environmental regulations that are deemed not to align with national security interests. The resolution specifically recommends that the Environmental Protection Agency immediately review and potentially suspend, revise, or rescind certain power plant regulations issued in May 2024.
HB 120 expands Montana's Commercial Property-Assessed Clean Energy (C-PACE) program to include multifamily housing facilities with at least five residential units. This change directly affects property owners and developers of qualifying multifamily buildings (e.g., apartment complexes), allowing them to finance energy efficiency and renewable energy upgrades through property assessments. The bill amends definitions to explicitly include these residential properties under the program, covering improvements like insulation, solar panels, and energy-efficient appliances. It maintains the existing financing mechanism where costs are repaid through property taxes over time, without requiring new debt or upfront payments from property owners. The law took effect immediately upon the governor's signature on April 7, 2025.
