Criteria and Development of Solar on 110 Closed Landfills in Minnesota
Minnesota’s closed landfill program (CLP), comprising 110 sites, hold important potential for solar PV development, and could also be assets in meeting the state’s greenhouse-gas-reduction goals. Currently, however, there is little information about which CLP sites are suitable for solar PV development, what barriers exist, and what actions are needed to address those barriers. In 2019 the Minnesota State Legislature provided funding to the Minnesota Environmental Quality Board (EQB) to conduct a study to address these questions. Barr was awarded the project and we present the findings of this study including a summary of the criteria for evaluating these sites and their potential for solar development. The results include important insights for other states, utilities, and developers for developing solar on landfills or other brownfields sites.
