SB 188 establishes Montana's "Solar Shares Act," creating a new framework for shared solar energy programs. It defines "shared solar facilities" (50kW-5MW systems serving multiple customers in the same utility area) and requires utilities to interconnect them, replacing net metering with "on-bill credits" for subscribing customers. Key provisions include: utilities must apply credits to subscribers' bills based on their share of generation, facilities must be within the utility's service territory, and credits can transfer between accounts or support low-income programs. The bill directly affects public utilities, shared solar facility owners, and residential/commercial customers who subscribe to shared solar.
SB 171 requires that 10% of excess state general fund revenue, after meeting budget stability and capital projects fund thresholds, be transferred to the Montana coal severance tax permanent fund (coal trust fund). This bill amends Montana's budget law to direct a portion of surplus funds - specifically, funds exceeding established reserve levels - to the coal trust fund instead of remaining in the general fund. The transfer applies when the budget stabilization reserve fund and capital projects fund exceed 16% and 12% of general revenue appropriations, respectively. The coal trust fund, which supports coal-related programs, would receive this additional funding without altering the state's primary budget processes.
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.
SB 343 would change how Montana allocates remaining coal severance tax revenue after other specified uses. Currently, until 2027, interest income from the coal trust fund is sent to the general fund for specific programs like agriculture development, small business centers, and library services. This bill amends the law to redirect all remaining coal tax revenue (after other allocations) directly to the coal severance tax permanent fund starting July 1, 2027, instead of the general fund. The policy change would shift funding away from current general fund programs toward the coal trust fund, which supports coal-dependent communities and projects.
HB 939 establishes new regulations for wind turbine generators, primarily affecting developers and property owners involved in wind energy agreements. The bill mandates a 1,500-foot setback for new wind turbines 500 feet or taller from occupied residences, unless the property owner approves a closer distance. It also sets a deicing standard, limiting rotor blade speed to 10% of maximum for certain tall turbines near residences, with a similar provision for property owner approval. Furthermore, it updates the required content for wind energy agreements executed after January 1, 2026.
HB 760 establishes consumer protection laws for individuals purchasing residential solar energy systems in Montana. It grants solar buyers a 3-business-day right to cancel a contract after signing, requiring written notification to the solar company or agent. Solar sales agents must provide a written explanation of these cancellation rights, which the customer must acknowledge. Additionally, the bill prohibits solar companies and sales agents from making deceptive statements about the costs, financing, or terms of solar energy system purchases during solicitations.
HB 623 establishes the conditions under which temporary spent nuclear fuel storage facilities can be sited within the state. It specifies that such facilities must be located on the site of an existing nuclear power generating facility and store fuel produced by that facility. Authorization for these facilities also requires a state recommendation from the Department of Environmental Quality (DEQ) and a license from the federal Nuclear Regulatory Commission. The bill amends existing law to clarify the DEQ's role in reviewing federal applications for these facilities, requiring applicants to submit their federal applications to the DEQ and pay a fee for the department's review and participation in federal proceedings.
HB 6 implements the Renewable Resource Grant and Loan Program by appropriating funds to the Department of Natural Resources and Conservation (DNRC). The bill allocates specific amounts for various grant types, including emergency projects, planning, irrigation development, private projects, and nonpoint source pollution reduction. Additionally, it appropriates $5.25 million for prioritized infrastructure grant projects to specific cities, towns, and water districts for improvements to wastewater systems, drinking water infrastructure, and stormwater control. Funds for these prioritized projects are awarded in a specified order until available money is expended.
HB 31 clarifies and revises the bonding requirements for wind and solar generation facility owners in Montana to ensure proper decommissioning. It mandates that facility owners submit a decommissioning plan and provide a bond to the Department of Environmental Quality (DEQ) within specific timeframes after commencing commercial operation. The DEQ determines the bond amount based on factors like site characteristics and salvage value. The bill also outlines various exemptions for facilities already bonded elsewhere or meeting certain size and operation criteria, and establishes penalties for non-compliance.
HB 55 revises the laws governing how public utilities plan for their customers' future energy needs. It requires public utilities to submit detailed resource plans every three years, including evaluations of renewable energy and demand-side management scenarios, and to hold more public meetings before submitting these plans. The bill establishes a special revenue account within the Department of Environmental Quality to fund an independent evaluator, paid for by fees charged to public utilities, who will assist in reviewing these plans. Additionally, the state commission can now engage independent consultants to evaluate utility plans, with these costs being recoverable in rates charged to customers.
