Please visit MPSC's generator interconnection webpage for more information. Each utility has its own interconnection procedures. The MPSC website provides links to this information for investor-owned utilities and member-regulated co-operative utilities, as well as hosting capacity maps for Consumers Energy and DTE Electric. Multifamily dwellings with multiple meters could submit projects under the residential rooftop solar or residential-serving community solar areas of the Solar for Savings funding opportunity.
If submitted as a residential rooftop solar project, the multifamily solar project would have to provide direct electric bill reductions to each participating low-income household. This could occur from installing solar arrays to service each household (one solar array for each low-income household meter in the multifamily dwelling). This approach is commonly seen in Michigan. If the utility allows its interconnection, it is also technologically possible to install one large solar array for a multifamily dwelling, where the power is divided and shared amongst different residents within the building.
If submitted as a residential-serving community solar project, the multifamily dwelling could install solar to serve dwelling units and common spaces. The project must meet U.S. EPA Solar for All Terms and Conditions for residential-serving community solar (e.g., 50 percent or more of the solar array benefits are shared with eligible low-income households in the same utility service territory, 5 Megawatts of alternating current (MWac) or smaller, etc.). The benefits from the community solar array could be shared in innovative methods, as long as the participant benefit requirements for the U.S. EPA Solar for All Program are met.
