Rochester Public Utilities

Solar Energy Information Hub 

Rochester Public Utilities (RPU) is the largest municipal utility in Minnesota and serves approximately 52,000 electric customers. RPU is currently experiencing a very limited demand for interconnections with a small customer base as compared to large Investor Owned Utilities, although they do have rebates in place for new distributed generation (DG) installations. The current process is very thorough, and requires close collaboration between RPU and Building Safety. This system ensures that Distributed Generation facilities in Rochester adhere to all necessary codes and permits before starting construction and that the safety and operating procedures of the utility crews are not compromised. This method of application processing can be supported due to the low volume of applications received each year.

RPU is subject to Minnesota’s Renewable Portfolio Standard (RPS). The RPS requires that 25% of energy come from renewable sources by 2025. Although RPU is not required to meet a solar carve out, the RPU board has publicly stated the intent to meet the 6% target within the RPS goal. Interconnection applications, particularly for residential solar, are expected to climb in the coming years with a decrease in technology costs and expansion of the federal income tax credit. While the existing solar enrollment process has proven to be effective for current application volumes, resources and departments may become overwhelmed with increased penetration. RPU can improve their scalability by providing more online information for customers and contractors, as well as improving their application tracking practices.

Customers Served (as of December, 2015)

  • Serves 52,000 customers
  • As of December 2015, 51 residential and 12 commercial for a total of 63 interconnection applications had been received
