Idaho Power supports customer choice and your interest in clean energy. Customers who install their own generation sources — usually solar, but also wind, hydropower, geothermal or fuel cells — can offset some or all of their energy needs. Customers remain connected to Idaho Power’s grid, drawing energy any time they aren’t producing their own power or need more than they can produce.
When certain customers (those billed under schedules 6, 8 and 84) generate more energy than they need, they send it back to Idaho Power’s grid and earn an energy credit for the excess energy produced. In addition to a fixed monthly service charge, the customer is billed for their net energy use, which is simply the amount they generate minus the amount they use over the monthly billing period. This billing structure is called net energy metering, or net metering.
Pending Cases Related to Pricing
The costs, benefits and compensation of net excess energy supplied by customer-owned on-site generation is currently being studied by Idaho Power, the Idaho Public Utilities Commission and interested parties. The outcome of the case could impact the time frame for estimated payback.
Make sure to stay up to date with active pricing cases through the Idaho Public Utilities Commission:
- Case studying the costs and benefits of residential and small general service customer generation on Idaho Power’s system (IPC-E-18-15)
- Case studying the costs and benefits of commercial, industrial and irrigation customer generation on Idaho Power’s system (IPC-E-19-15)
- Case studying ways to recover the fixed costs of providing electric service to customers (IPC-E-18-16)
Customer Generation Eligibility and Pricing
Customers approved to generate their own electricity are billed under different pricing policies, often called rate schedules (or tariffs). Use the chart below, to find your rate schedule or view all rate schedules.
|Current Schedules Eligible for Customer Generation||Applicable Schedule with Customer Generation||Allowable Amount of Capacity Connected|
|Idaho Residential (Schedule 1)||Idaho Residential Service On-site Generation (Schedule 6)||Up to 25 kilowatts|
|Idaho Small General Service (Schedule 7)||Idaho Small General Service On-Site Generation (Schedule 8)||Up to 25 kilowatts|
|Oregon Residential (Schedule 1) and Small General Service (Schedule 7)||Customer Energy Production/Net Metering Service (Schedule 84)||Up to 25 kilowatts|
|Idaho and Oregon Irrigation (Schedule 24), Large General Service (Schedule 9) and Industrial (Schedule 19)||Customer Energy Production/Net Metering Service (Schedule 84)||Up to 100 kilowatts|
For projects over 100 kW refer to Generator Interconnection.
Solar, wind and other on-site generation sources must be installed safely. There are specific equipment requirements and designs depending on your rate schedule and size of system.
Schedule 72 Interconnections to Non-Utility Generation applies to all rate schedules and outlines the interconnection requirements and application process.
Customer Generation Interconnection Requirements include line diagrams, equipment specifications and testing requirements to ensure your system is configured properly.
