Ohio Interconnection Standards
|Date Last Updated||8/13/2014|
|Policy Type||Interconnection Standard|
|Policy Administrator/Contact Office||Public Utilities Commission of Ohio (PUCO)|
|Policy Initiation Date||10/22/2007|
|Policy Summary||The PUCO has adopted interconnection standards for distributed generation (DG), including CHP. Ohio's interconnection standards provide for three levels of review for the interconnection of DG including CHP systems up to 20 MW, which apply to customers of the State's investor-owned utilities. There are three main levels of interconnection: |
All systems must meet IEEE 1547 and UL 1741 standards and may not be interconnected at the transmission level. Each utility must designate an employee or office to handle interconnection application requests. Utilities may not require additional liability insurance beyond proof of insurance. The rules include a provision for alternative dispute resolution, and for formal complaints brought by applicants and interconnected customers.
- Level 1: applies to small systems and is divided into three subsections:
(a) Level 1 is a simplified review process for inverter-based systems up to 10 kW that are renewably fueled.
(b) Level 1.1 is a simplified review process for inverter-based systems up to 10 kW that are located on the load side of an area network.
(c) Level 1.2 is a simplified review process for systems up to 50 kW that are interconnected to an area network.
- Level 2: applies to certified, inverter-based or synchronous systems up to 2 MW. This level represents an expedited review procedure where the technical screens, fees, and timelines are detailed in the rule. An external disconnect switch is required.
- Level 3: applies to inverter-based or synchronous systems up to 20 MW that do not qualify for Level 1 or Level 2 certification. The technical screens, fees, and timelines are detailed in the rules and an external disconnect switch is required.
|CHP Eligibility Requirements||Both fossil-fueled and renewably-fueled CHP systems are eligible for standardized interconnection.|
|Eligible Project Size (MW)||Standardized interconnection applies to systems up to 20 MW.|
