Generators and Backup Power

Every install is different. The final cost depends on the generator size, fuel type, placement, and installation complexity. Because those factors vary home to home, the only reliable way to get an accurate number is an in-home consultation. Malco Electric provides free consultations with detailed, no-obligation quotes, no surprises.

Generator sizing depends on what you want to power. A 10 to 14kW generator handles essential circuits. A 16 to 22kW generator powers most typical homes. Larger homes with pools, multiple HVAC systems, or well pumps may need 24kW or more. We perform a load calculation to determine your specific needs.

Natural gas generators can run indefinitely as long as gas supply is available. Propane generators run until the tank is empty. A 500-gallon tank typically provides 5 to 7 days of continuous power at 50% load. Standby generators are designed for extended operation.

Yes, generator installations require electrical and often gas permits in Texas. The work must pass inspection. Malco Electric handles all permit applications, inspections, and coordination as part of our installation service.

It depends on your utility and the type of system. A standby generator that never exports power to the grid is treated differently than solar or battery storage. In Pedernales Electric Cooperative territory, much of the Hill Country west of Austin, PEC's published requirements state that standby generators must not export power to the cooperative's distribution system, and members may connect using a UL-approved open-transition transfer switch. That is not the same as the interconnection application required for distributed generation.

Automatic standby generators detect an outage and start within 10 to 30 seconds. The automatic transfer switch disconnects your home from the grid and connects to the generator, without any action from you.
