A Final Approval to Operate may also be called a “Certificate of Completion” (CoC) or “Permission to Operate” (PTO) and is issued by the interconnecting utility company. The final approval to operate date is indicated on the CoC or PTO as the date in which the utility grants final approval to turn on and operate the system. Applications may not be submitted until final approval to operate the system has been granted by the interconnecting utility. The approval to operate date must match the date on the CoC or PTO uploaded on Step 4 of the application.
