Before you (the interconnection customer [IC]) submit an Interconnection Request (IR) to the ISO to interconnect a new generating facility or elective transmission upgrade (ETU) or modify an existing facility, you must determine whether your project will be interconnecting to the ISO-administered transmission system under the ISO’s process or interconnecting through the state process. A generating facility participating in the wholesale electricity markets that originally interconnected under a state process will need to follow the ISO’s interconnection process for any modifications. “Interconnection Process” training is available on the Training Materials webpage.
The ISO-administered transmission system consists of the following types of facilities:
Use the chart in this section to assess whether the interconnection process applies to your project. If you are not sure, please consult with the circuit owner and the ISO to determine whether the facility has become part of the administered system for interconnection purposes.
For details, see the ISO’s Distribution-Connected Generation Guidance presentation.
Is your project interconnecting to the ISO-administered transmission system (i.e., a PTF, non-PTF, or for distribution facilities subject to the ISO Tariff)?
Is your project exempt? Exemptions:
Contact the distribution company/owner of the distribution facility that is not subject to the ISO Tariff.
