Generac, Kohler, and Briggs standby generators with automatic transfer switches.
Middle Tennessee storms knock out power every season. A whole-house standby generator keeps your home running — HVAC, refrigeration, well pump, sump pump, and lights — without ever flipping a switch. We size, install, permit, and commission the entire system.

A standby generator is more than a box on a pad. It's a fully integrated system: properly sized generator, automatic transfer switch (ATS), service-rated disconnect, gas line, concrete pad, and panel integration. Done right, you don't even notice when the power goes out.
A typical standby generator install project by Nashville Electric Pros includes:
A whole-home generator backs up everything: HVAC, water heater, range, all outlets. An essentials system backs up a sub-panel of critical circuits — usually cheaper but more limited.
A 14kW unit handles a small home with one A/C and basics. 22kW–26kW handles most full Middle TN homes with two HVAC units. 38kW–48kW for large homes with multiple HVAC units and high-load appliances.
Natural gas means unlimited runtime — no tank to fill — but requires a city gas line. LP is the answer for rural Joelton, Whites Creek, and acreage homes without natural gas.
Generac is the most common, with the widest service network. Kohler builds excellent commercial-grade units. Briggs & Stratton offers solid value. We install all three.
