Idaho Power Service Upgrade Process in Twin Falls — What to Expect
Idaho Power Service Upgrade Process in Twin Falls — What to Expect from Start to Finish
In This Guide
What Is an Idaho Power Service Upgrade?
An Idaho Power service upgrade refers to any change to the electrical connection between Idaho Power’s distribution system and your home or farm meter — including upgrading service amperage (100A to 200A or 400A), replacing a failed meter base, changing the service entrance configuration, or moving the meter location. These changes require Idaho Power’s direct involvement because they control the transformer, the service drop wires, and the meter.
⚡ Important Distinction
Not every panel upgrade requires Idaho Power involvement. Replacing a Federal Pacific panel with a new 200A panel at the same service size — same amperage, same meter base — often doesn’t require an Idaho Power service call. Only work involving the meter base, service entrance conductors, or amperage increase requires their participation.
When Do You Need Idaho Power Involved in a Twin Falls Electrical Project?
You need Idaho Power coordination in Twin Falls when your project involves:
- Increasing service amperage (100A to 200A, 200A to 400A) — requires new meter base and service entrance conductors
- Replacing a failed or damaged meter base
- Moving the meter location on the building
- New service installation for a new structure or addition
- 3-phase service installation or upgrade (farms, commercial)
- Underground service conversion from overhead
The Full Idaho Power Service Upgrade Process in Twin Falls
Step 1: Your Electrician Pulls the Permit
The process starts with the City of Twin Falls Building Department permit — not with Idaho Power. We pull the electrical permit at 203 Main Ave E before calling Idaho Power. Idaho Power won’t schedule their crew until permits are in order.
Step 2: Your Electrician Calls Idaho Power
We call Idaho Power’s Twin Falls construction department to request a service disconnect, which is required before we can work on the meter base or service entrance. Idaho Power coordinates the disconnect date with our installation schedule. This is a critical sequencing step that homeowners don’t need to handle — we make the call.
Step 3: New Meter Base and Service Entrance Installation
Once Idaho Power cuts their side, we install the new meter base (sized for the new amperage), new service entrance conductors, and the new panel. Typical installation time for a 200A upgrade: 6–10 hours.
Step 4: Idaho Power Reconnects and Sets the Meter
After we complete our side of the work, Idaho Power returns to reconnect their service drop conductors and set the meter. They inspect the meter base for compliance with their standards before reconnecting. The meter base must meet Idaho Power’s specifications — our installations always do.
Step 5: City of Twin Falls Inspection
After Idaho Power reconnects, we schedule the City of Twin Falls electrical inspection. The inspector verifies our work meets 2023 NEC code. On a properly done service upgrade, this is typically a pass-on-first-visit.
Step 6: Final Documentation
We provide you with the permit, inspection card, and any Idaho Power paperwork. Your insurance company gets documentation of licensed, permitted, inspected work.
Timeline and What Causes Delays in Twin Falls
The most common question we get from Twin Falls homeowners is: how long will I be without power? Here’s a realistic timeline:
| Step | Timeline | Notes |
|---|---|---|
| Estimate and permit filing | 1–3 business days | We file, you don’t need to do anything |
| Idaho Power disconnect scheduling | 3–10 business days | Busier in summer — plan ahead |
| Installation day (no power) | 6–10 hours | Start early, power back same day |
| Idaho Power reconnect | Same day or next morning | We coordinate the same-day reconnect |
| City inspection scheduling | 1–5 business days after | Inspector comes to the house |
What Causes Delays in the Twin Falls Area
The most common delay is Idaho Power’s schedule — their Twin Falls construction crew handles a significant volume of service work. During summer months (May through September) and at the beginning of irrigation season when farms need 3-phase upgrades, their schedule gets backed up. We recommend starting the process as early as possible if you have a specific date in mind — like before a home sale.

FAQ — Idaho Power Service Upgrades in Twin Falls
Do I need to contact Idaho Power myself?
No. We handle all Idaho Power coordination directly. You don’t need to call Idaho Power, schedule anything with them, or navigate their construction department. We make that call as part of every service upgrade project in Twin Falls.
What if I’m in MVEC territory, not Idaho Power?
Magic Valley Electric Cooperative (MVEC) serves Jerome County, Gooding County, and parts of Twin Falls County. If you’re in MVEC territory, the process is similar but the paperwork and timeline differ. We work with MVEC regularly — call us and we’ll tell you which utility serves your property and what their specific process looks like.
Will I be without power all day during the upgrade?
Yes — for the installation portion. Idaho Power cuts their side early in the morning, we work through the day, and Idaho Power returns in the afternoon to reconnect. For most Twin Falls service upgrades, power is restored the same day. We’ll give you the specific expected schedule before installation day so you can plan accordingly.
