Texas homeowners have learned hard lessons about power grid reliability. The 2021 winter storm was a wake-up call for many — days without power in sub-freezing temperatures. But even in non-historic events, the Central Texas grid can be stressed by summer heat, severe thunderstorms, and equipment failures. A properly installed generator is one of the most practical investments a Texas homeowner can make.

This guide covers everything you need to know about generator installation in Kyle and the greater Austin area — from sizing to transfer switches to what the actual installation looks like.

Portable vs Standby Generators

There are two fundamentally different generator approaches, and the right one depends on your needs and budget.

Portable Generators

Portable generators are gas-powered units you store in the garage or shed and deploy when needed. They're significantly less expensive upfront but require manual operation — you have to be home, you have to fuel them, and you have to connect them properly.

Important: a portable generator must never be connected directly to your home's wiring through an outlet (backfeeding). This is illegal, can destroy your generator when power returns, and can kill utility workers. A proper transfer switch or interlock kit is required — no exceptions.

Standby Generators

Standby generators are permanently installed outside your home, connected to natural gas or propane, and linked to an automatic transfer switch (ATS). When the grid goes down, the ATS detects the outage, starts the generator automatically, and transfers the load — all in about 10–30 seconds. When power returns, it reverses the process.

Standby generators require licensed electrical installation and coordination with your gas utility. Brands like Generac, Kohler, and Briggs & Stratton offer units ranging from 7.5kW for essential circuits to 20kW+ for whole-home coverage.

If you experienced 2021's winter storm and vowed never again — a standby generator with an ATS is the answer. It runs automatically, even if you're not home.

Automatic Transfer Switches (ATS) vs Manual Transfer Switches

Regardless of whether you choose a standby or a well-wired portable generator setup, you need a transfer switch. Here's the difference:

  • Automatic Transfer Switch (ATS) — Monitors utility power continuously. When it detects an outage, it starts your generator and transfers the load within seconds. Reverses automatically when utility power returns. Required for standby generators. Requires no action from you.
  • Manual Transfer Switch (MTS) — A dedicated sub-panel wired to selected circuits. You manually switch the source from utility to generator. More affordable, but requires you to be home and physically operate the switch.
  • Interlock Kit — A mechanical device added to your existing panel that prevents the main breaker and generator breaker from being on simultaneously. The simplest and least expensive code-compliant solution for portable generators.

Sizing Your Generator

Generator sizing is one of the most common mistakes homeowners make. Under-sizing means some equipment won't run; over-sizing means you're paying for capacity you don't need.

Here's a general starting framework for Central Texas homes:

  • Essential circuits only (~7,500–12,000W) — Refrigerator, lights, select outlets, window AC unit, internet router, phone chargers. Appropriate for a well-planned manual setup or a smaller standby unit.
  • Partial home (~12,000–17,000W) — Adds a 2-ton HVAC system and larger appliances. Very comfortable during a Texas summer outage.
  • Whole home (~20,000W+) — Powers everything, including electric range, large HVAC, and high-draw appliances. No lifestyle changes required during an outage.

We do a load calculation during our estimate to right-size your system. Bigger isn't always better — an oversized generator runs inefficiently at low load and costs more to fuel.

Fuel Options in Central Texas

  • Natural gas — The most convenient option if you have natural gas service. Gas continues flowing during most outages. No fuel storage required. Generac and Kohler both make excellent natural gas standby units.
  • Propane — If you don't have natural gas, propane is the alternative for standby generators. Requires a propane tank (100–500 gallons is common for whole-home backup). Tank must be filled before outage season.
  • Gasoline — What portable generators run on. Convenient to obtain but requires storage, rotation, and stabilizer for long-term storage. Fuel supply can be disrupted during major outages when everyone is buying gas simultaneously.

What the Installation Process Looks Like

  • Site assessment and estimate — We evaluate your panel, identify the transfer switch type and location, assess the generator pad location, and provide a written quote.
  • Gas coordination — For natural gas standby units, we coordinate with your gas utility to extend the gas line to the generator location. (This is a separate scope typically handled by a licensed plumber or gas fitter.)
  • Generator pad — Standby generators sit on a concrete or composite pad outside the home, away from windows and doors per clearance requirements.
  • Electrical work — We install the transfer switch, run circuits from the panel, connect the generator's electrical connections, and test the complete system.
  • Permit and inspection — Generator installation requires a permit. We pull it and handle the inspection.
  • Load test and walkthrough — We run the generator under load and walk you through operation, maintenance indicators, and weekly exercise settings.
