Generators and potential generators who wish to connect to Idaho Power Company's electrical system will find the following information and links helpful. Applications are placed in the queue and are processed on a first come, first serve basis. View the application list. This link will take you to the OASIS site. From the left menu bar, click "Generation Interconnection" and then "Generation Interconnection Queue."

Net Metering (less than 100KW) Application (PDF, 30KB)

Schedule 84 for Idaho (PDF, 102KB)
Schedule 72 for Idaho (PDF, 279KB)

Below are the steps and associated forms necessary for Small Generators (up to 20 MW) and for Large Generators (greater than 20 MW). The process is the same for all generators, except for the forms included as shown. Click for Requirements for Generator Interconnection (PDF, 156KB).

Generators up to 20 MW

Process for Generators up to 20 MW Small Generator Interconnection Procedures (PDF, 149KB)

Step 1: The Interconnection Application (PDF, 45KB) must be completed and submitted for all Generator Interconnections to the Idaho Power System.

Step 2: Feasibility Analysis (PDF, 21KB) includes general review of system impact, capacity constraints and possible problems with the customer's choice of point of interconnection.

Step 3: System Impact Study (PDF, 24KB) provides a detailed assessment of the transmission system adequacy to accommodate the application. This step may not be necessary for some projects depending on size and location of the project.

Step 4: Facility Study (PDF, 36KB) includes design and engineering studies to determine the design and specifications. Construction options are provided to the customer.

Step 5: Interconnection Agreement all projects up to 20 MW are subject to technical requirements under the Interconnection Agreement once the project becomes operational.

a) PURPA Interconnection Agreement (PIA) (PDF, 1M) will be filed with the Idaho Public Utilities Commission under Idaho Power's Rate Schedule 72.

b) Small Generator Interconnection Agreement (SGIA) (PDF, 111KB) an SGIA must be filed with the FERC for all projects up to 20 MW who are selling energy off-system.

Process for Generators greater than 20 MW Large Generator Interconnection Procedures and Agreement (PDF, 210KB)

Step 1: The Large Generator Interconnection Application (PDF, 30KB) must be completed and submitted for all Generator Interconnections greater than 20 MW into the Idaho Power System. 

Step 2: Large Generator Feasibility Analysis (PDF, 42KB) includes general review of system impact, capacity constraints and possible problems with the customer's choice of point of interconnection.

Step 3: Large Generator System Impact Study (PDF, 36KB) provides a detailed assessment of the transmission system adequacy to accommodate the application.

Step 4: Large Generator Facility Study (PDF, 35KB) includes design and engineering studies to determine the design and specifications. Construction options are provided to the customer.

Step 5: Interconnection Agreement all projects greater than 20 MW are subject to technical requirements under the Interconnection Agreement once the project becomes operational.

Large Generator Interconnection Agreement (LGIA) (PDF, 386KB) must be filed with the FERC for all projects greater than 20 MW.
