Energy (Wind)

This bill requires public utilities in Montana to transfer any unused kilowatt-hour credits from customer-generated solar or wind energy to a state fund that supports low-income energy assistance programs. Under the new rules, when a customer generates more electricity than they use, the excess is credited to their account for the next billing period, but any remaining credits at the end of a 12-month period must be given to the utility without payment to the customer. The utility then contributes these credits to a designated fund administered by the Department of Public Health and Human Services, which uses the resources to help low-income households with energy costs. This change affects residential and commercial customers who generate their own electricity and the public utilities that serve them.

This bill reclassifies certain wind energy facilities from Property Tax Class Fourteen to Class Thirteen in Montana. Currently, wind facilities are excluded from Class Seven (taxed at 8%) but fall under a higher-tier classification; this change moves them to Class Thirteen, which is taxed at 6% of market value. The bill amends Montana Code Annotated sections 15-6-137 and 15-6-156 to explicitly include wind generation facilities under Class Thirteen’s tax rate. This directly affects wind energy facility owners by reducing their property tax burden from 8% to 6%. The change applies immediately and retroactively, affecting existing facilities without requiring new construction.

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.

HB 915 revises the property taxation of certain wind generation facilities in Montana. The bill reclassifies specific wind generation facilities, moving them from Class Fourteen to Class Thirteen for property tax purposes. This change means these facilities would be taxed at 6% of their market value, which is the rate established for Class Thirteen property. The bill also includes provisions for an immediate effective date and retroactive applicability.

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.
