Idaho Power Exports at Avoided Cost — Self-Consumption and Battery Are Essential
Idaho Power Credits Solar Exports at the Avoided Cost Rate — Well Below Retail. Every Kilowatt-Hour Self-Consumed at Retail Is Worth 2–3× a Kilowatt-Hour Exported. Battery Is the Key Tool in This Market.
Idaho Power is the primary utility serving Boise and the Treasure Valley. Unlike full retail net metering markets, Idaho Power credits solar exports at the avoided cost rate — the cost Idaho Power avoids by not generating that kilowatt-hour itself. The avoided cost rate is substantially below the retail electricity rate, making self-consumption of solar significantly more valuable than exporting. Battery storage that captures midday surplus and dispatches it for evening use dramatically improves Boise solar economics. Boise has been one of the fastest-growing US metros for years, driven by technology sector relocation, remote workers, and lifestyle migration from California and the Pacific Northwest.
Idaho Power · Avoided Cost Export Rate · Below Retail
⚠️Idaho Power net metering credits solar exports at the avoided cost rate — below full retail price
⚠️Avoided cost rate is substantially below retail — self-consumption at retail is 2–3× more valuable
⚠️Midday solar surplus that exports earns far less than surplus captured by battery for evening use
✅Idaho Power interconnection: submit simultaneously with Ada County or city building permit
✅Idaho property tax exemption for solar energy systems — permanent
Self-Consumption · Battery Essential · Fast-Growing Boise Metro
✅Battery captures midday surplus and dispatches for evening use at full retail offset value
✅Right-sizing to consumption rather than oversizing maximizes avoided-cost ROI
✅Boise is one of the fastest-growing US metros — new construction solar pipeline is large
✅NEC 2020 under Idaho state adoption
✅Idaho sales tax exemption on solar energy equipment
⚠️ Idaho Power's avoided cost export rate means oversizing a Boise solar system creates excess exports worth far less than self-consumed solar. Designing for self-consumption first — then battery to capture surplus — is the correct Boise solar strategy. We include a self-consumption optimization note in every Boise plan set deliverable.
Why Boise Installers Outsource
System Oversized for Export at Low Avoided Cost. Battery Not Proposed. AHJ Fragmentation in Treasure Valley.
Oversizing a Boise Solar System Creates Low-Value Exports at Avoided Cost Rate
Idaho Power's avoided cost rate is substantially below the retail electricity price. Installers from full retail net metering states sometimes design for maximum production, assuming 1:1 credit for every exported kilowatt-hour. In Idaho Power territory, every exported kilowatt-hour above the self-consumption offset earns avoided cost value — not retail. Right-sizing to consumption with battery is the correct Boise approach.
Proposing Solar Without Battery Leaves Most of the Financial Value on the Table
Without battery, midday Boise solar surplus exports at avoided cost. With battery, that same surplus charges the battery and is dispatched at evening peak, earning the full retail offset. For Boise customers, battery is the financial mechanism that closes the gap between retail and avoided cost. A Boise solar proposal without battery often underperforms customer expectations.
Routing a Meridian or Eagle Address to City of Boise Building
City of Boise Building and Development Services covers only Boise city-limit addresses. Meridian, Nampa, Caldwell, Eagle, Star, and Kuna each have separate building departments. A plan set addressed to City of Boise for a Meridian address is rejected immediately. AHJ confirmation per address is mandatory for every Treasure Valley project.

Four Things That Define Solar in Boise.
Avoided Cost
Idaho Power Avoided Cost Export — Self-Consumption Is 2–3× More Valuable
Idaho Power credits solar exports at the avoided cost rate — substantially below the retail electricity rate. The avoided cost represents the fuel and generation cost Idaho Power avoids by not generating that electricity itself. It does not include transmission, distribution, or utility overhead costs. Every kilowatt-hour self-consumed at retail is worth 2 to 3 times a kilowatt-hour exported at avoided cost — the entire Boise solar strategy hinges on maximizing self-consumption.
Battery Essential
Battery Is the Financial Mechanism That Makes Boise Solar Work
Without battery, midday Boise solar surplus exports at avoided cost. With battery, that surplus charges a storage system and is dispatched during evening peak hours, earning the full retail offset value. Battery can convert 30 to 50% of a system's production from export value to retail offset value. For Idaho Power customers, battery is not an optional upgrade — it is the tool that makes residential solar financially compelling.
Fast Growth
Boise — One of the Fastest-Growing US Metros for a Decade
Boise has been one of the fastest-growing large metros in the United States for over a decade, driven by technology sector relocation, remote workers, and lifestyle migration from California and the Pacific Northwest. The combination of population growth, Idaho Power rate increases, and new construction volume creates a large and growing residential solar pipeline across Ada County, Canyon County, and surrounding Treasure Valley communities.
ID Incentives
Idaho Property Tax and Sales Tax Exemptions — Two State Incentives
Idaho offers a property tax exemption for solar energy systems and a sales tax exemption on solar equipment. Idaho has no state solar income tax credit in 2026. These two state incentives combined with Idaho Power net metering and rising electricity rates form the Boise solar financial case after the federal 25D credit expiration.
