- Demonstration of site control
- $500 deposit
3. Fast Track Screens: 15 Business Days
Small Generator Interconnection Agreement (SGIA)
Screens will be performed as set forth in section 2.2.1 of the SGIP.
If the project passes all screens, it will proceed with executing an SGIA.
If the project fails the screen, it may proceed with executing an SGIA per section 2.2.3 of the SGIP, or it will proceed in accordance with Sections 2.3, 2.4, and/or Section 3 of the SGIP.

NOTICE: Idaho Power has transitioned to an online application portal for small generation interconnection pre-application requests only. All pre-application requests must be submitted through — and are managed within — the Small Application Portal. Standard small and fast track interconnection requests must continue to be submitted via email. Instructions for creating a portal account can be found on the portal homepage.
