Interconnection checklist

UPDATE:  On December 4, 2013, the PUCO adopted amended rules for electric interconnection services and standards in Chapter 4901:1-22 of the Ohio Administrative Code in accordance with the state of Ohio’s 5-year rule review procedures.

The amended rules create an improved and more streamlined process for interconnection with an electric distribution utility. Among the improvements, the PUCO reformed the interconnection application review process, including simplifying Level 1 review of inverter-based systems, raising the review level from 10 kW to 25 kW system nameplate capacity and reducing the review timeframe from 1 month to 15 business days. The PUCO further approved an expedited Level 2 review with a supplemental review option, and a pre-application review opportunity which will provide for a basic preliminary review within a short timeframe.

Questions to consider

Want to simplify the review of your interconnection application? Please take a few minutes to consider the following:

  1. Is your generating equipment (either by itself or as part of a group of generators) larger than 20 megawatts? Please contact your local utility.
  2. Is your generating equipment 25 kW or less with a certified inverter? Ask your local utility company for the short application form. For everything else, ask for the standard application form.
  3. Do you want to use your generating equipment for net metering? Certain restrictions may apply. Under Ohio law, net metering is a customer billing arrangement, not a sale of electricity to the customer’s electric utility or retail electricity supplier. To qualify for net metering, the owner’s generating equipment must be installed primarily for the owner’s own use.
