Generator Installation in Twin Falls, Idaho
Twin Falls winters hit 23°F in December and bring ice storms that knock out power for days. Dairy farms can’t tolerate a 6-hour outage without milk spoilage losses. A properly wired standby generator with an automatic transfer switch changes that calculus completely.
Generator Installation — What Tervano Electric Does
We handle the electrical side of generator installation. The generator unit itself is purchased separately through your generator supplier (Generac, Kohler, Cummins, etc.) — we coordinate with them on specifications and timing. Here’s what we do:
🔄 Automatic Transfer Switch (ATS) Installation
The ATS is the brain of your standby generator system — it detects a power outage and automatically switches your electrical system to generator power within seconds. We install and wire the ATS, integrate it with your main panel, and test the automatic switchover. This is permitted work requiring a City of Twin Falls inspection.
🔌 Generator Circuit and Connection
We wire the connection from the generator unit to the ATS, including appropriate disconnect switches, weatherproof enclosures, and any required conduit runs. We size the wiring correctly for your generator’s output — undersized wiring on a generator circuit is a fire risk.
⚡ Load Selection (Partial vs Whole-Home)
We can wire a whole-home generator that powers everything, or a critical load panel that powers only your most important circuits (heat, refrigerator, sump pump, lighting, medical equipment). We discuss your priorities before installation and design accordingly.
🌾 Agricultural Generator Systems
For dairy farms, irrigation pump systems, and cold storage operations, generator reliability is not a comfort issue — it is a financial one. We install and wire farm generators with appropriate ATS sizing for 3-phase loads, motor starting requirements, and MVEC or Idaho Power interconnection compliance.
Generator Installation Costs in Twin Falls
Electrical work for generator installation (transfer switch, wiring, permit, inspection): $3,000–$8,000 for residential. Farm/agricultural systems: $4,000–$12,000+ depending on load size and 3-phase requirements. The generator unit itself is a separate cost (Generac 22kW whole-home unit runs approximately $5,000–$8,000 at the supplier level).
