MISO provides generators reliable, non-discriminatory access to the electric transmission system. Follow these steps to connect a generator to the transmission system. If you need help, contact our Generator Interconnection Team.
The generator interconnection application requires detailed technical data and information about your Generator Interconnection (GI) Project. MISO suggests gathering all required information before you begin to complete the electronic form. The application is comprehensive and may feel time-consuming, however compiling Appendix 1 and all required data now will enable you to meet upcoming milestones and deadlines as your project advances through the Definitive Planning Phases.
Prior to beginning your application process, consider attending a Queue Process Workshop or Online Application Training Workshop to gain understanding of the MISO Generator Interconnection Process. The Queue Process Workshop and Online Application Training Workshop, provided by MISO at no cost, is available to anyone interested in the Generator Interconnection Process. As an Interconnection Customer, you have the opportunity to fill out an Ad Hoc Meeting request to discuss your potential Point of Interconnection and other issues concerning your Generator Interconnection Project with the Transmission Owner. MISO also provides GI-related updates regularly at the Interconnection Process Working Group (IPWG) meetings.
A completed application includes electronic copies of each of the following items:
For ICs requesting an informational study to aid in making project business decisions, see Appendix 5 of Attachment X for an Optional Study. Optional studies will be performed based on assumptions outlined by the IC and the results of such informational studies will be non-binding.
The Generator Interconnection Online Application Guide is now available in the MISO Customer Learning Center. Please view instructions on how to access the training.
