Revise alternative energy project laws to require a bond prior to construction

This bill requires wind and solar power project owners in Montana to post a financial bond before construction begins to ensure funds are available for decommissioning the facilities when they are no longer operational. The law applies to large-scale wind and solar projects with specific capacity thresholds and mandates that owners submit a detailed decommissioning plan and cost estimates to the state Department of Environmental Quality prior to starting commercial operations. Key provisions include setting a 12-month deadline to begin decommissioning after a facility is abandoned or reaches the end of its useful life, with completion required within 24 months unless an extension is approved. The bill also defines decommissioning activities such as removing equipment, restoring land to its original condition, and allows for alternative restoration agreements if mutually agreed upon with property owners.
