New Electrical Service & Power Pole Installation in Twin Falls, Idaho
New home, shop, barn or RV hookup? We install the service — meter base, main panel or disconnect, grounding, trenching and the power pole where needed — and coordinate with Idaho Power or MVEC so the utility can connect you.
The pieces of a new electrical service
Meter base and service panel
The utility’s meter and your main panel or disconnect, sized for your load — commonly 100A, 200A or 400A for homes and shops.
Power pole or service mast
On rural properties a pole carries the meter and panel; on buildings a mast and weatherhead do the job. We set it to the utility’s requirements.
Grounding
A grounding electrode system installed and bonded to code — checked at inspection.
Trenching and conduit
Underground service and feeders to a house, shop or barn, buried at code depth.
Temporary power
A temporary service for construction so crews have power while the permanent service is built.
Utility paperwork
Applications and scheduling with Idaho Power or MVEC — we handle the electrical side and keep you informed.
Idaho Power or MVEC — it depends on your property
Different parts of Twin Falls County are served by different utilities, and their requirements and timelines differ. We confirm which utility serves your property before the estimate.
Size the service
Load calculation for your home, shop, barn or equipment.
Permit
We pull the electrical permit with the permitting authority that covers your property.
Install, inspect, connect
We install the service, pass inspection and the utility makes the final connection on its schedule.
See also the Idaho Power service upgrade process. Utility scheduling is outside our control, so we plan early and keep you updated.
What a service costs
Cost depends on service size, distance from the utility, trenching and utility fees. For reference, our cost guide lists 3-phase service installation at $4,000 – $12,000+ for farm and commercial properties. Residential and single-phase services are quoted per site in writing — we visit, measure and give you a written estimate before work starts.
Frequently asked questions
How long does a new service take?
It depends on the utility’s schedule as much as ours. We start the utility paperwork early and tell you where the process stands.
What is the difference between a service upgrade and a new service?
A service upgrade increases the capacity of an existing service. A new service brings power to a new building or property. See panel upgrades.
Can you install a temporary power pole for construction?
Yes. A temporary service gives your crew power during the build, and we convert or replace it when the permanent service goes in.
Do I need a permit for a new service?
Yes — and an inspection before the utility will connect. We handle both. See electrical permits.
Do you install services for farms and barns?
Yes, including 3-phase. See agricultural electrician.
