Effective October 18, 2021, Maine law requires developers of solar power projects that occupy 3 or more acres to have an approved decommissioning plan and accompanying financial assurance sufficient to cover the cost decommissioning as outlined in the plan.  The law applies to projects on which construction starts on or after October 1, 2021, as well as to projects that undergo a transfer of ownership after October 1, 2021. 

The Department is responsible for administering the law in all organized municipalities and in the unorganized and deorganized parts of Maine typically served by the Land Use Planning Commission if (a) the solar energy development requires a permit under the Site Location of Development Law or (b) straddles an organized/unorganized boundary.

Approval of a solar energy development decommissioning plan may be obtained by filing an application with the Department.
