Customer Generation – Application

This application is an interconnection request for existing Idaho Power customers who wish to install a Distributed Energy Resource (DER) comprised of an energy generation system (e.g., solar) or energy storage system (e.g., battery backup). Once submitted an electronic printable version of this application will be emailed with instructions for signing and mailing the form with the application fee. Upon receipt of the application and fee, Idaho Power will review the project and determine if any upgrades to the electrical grid are needed. If no upgrades are needed, you will receive an approval to proceed. Application and fee expire one year after review date. The review is based only on the size of your DER and the grid components that will accept your DER’s exported energy. If you are making other modifications to your electric service (e.g., installing a larger service panel), upgrades to the distribution service may be required. If electric service modifications are needed to accommodate the onsite generation system, to ensure the meter is accessible 24/7 as required, or for any other reason, contact Idaho Power's Customer Care line at 800-488-6151 to initiate the process. Idaho Power does not review for state electrical or building requirements. Please ensure you get the proper permits and inspections for your planned work.

All customer generation systems must satisfy the requirements of Schedule 68 Interconnections to Customer Distributed Energy Resources. Upon completion of the interconnection process, customers will take service under the applicable schedules in Idaho Power’s tariff.

Maximum System Size

• Residential and Small General Service: 25 kW AC.
• Large General, Industrial, and Irrigation Service: 100 kW AC or the service point’s highest billed demand in the last 12 months.
• Billed demand is defined as assessed charges for demand that a customer is billed for. For irrigation customers, demand charges are only assessed/billed during in-season billing periods. The in-season rates begin with the customer’s meter reading for the May billing cycle and end with the customer’s meter reading for the September billing cycle.
• AC-coupled energy systems count toward the total DER for the Feasibility Review, but do not count toward the maximum system size noted above.

Projects are reviewed based on the proposed total AC nameplate capacity as defined in Schedule 68 and AC unity power factor (1 kilovolt-ampere (kVA) = 1 kilowatt (kW)).

For generation systems with battery storage: Depending on the system design and location of the AC Disconnect, there is a potential that the property may not receive power from Idaho Power in cases where the AC disconnect switch is turned off. Please work with your installer to mitigate this situation.
