Success Story

Restoring Power for Peace of Mind

The main water treatment facility in a major Midwestern city lost its second power line feed and they needed a second power source. Equipment to complete the job was spread across the country, and time was limited.

United Rentals worked quickly and effectively to install 28 MV of temporary power as a reliable second source. After testing the system, it proved to be fully functional should the plant need to run during an emergency. To quote the client, “This was a 3-legged race to restoration of power and you won.”

Frequently Asked Questions

What is temporary power for utilities and power generation facilities?

Temporary power for utilities is mobile generation, distribution and testing equipment that keeps electricity flowing when permanent infrastructure is offline, overloaded or being upgraded. It includes industrial generators, transformers, power distribution equipment and load banks. Utilities and power producers use it to keep interruptions short, protect critical facilities and maintain service to customers.

When do utilities need temporary power generation?

Utilities typically need temporary power during planned maintenance and upgrades, equipment failures, storms and other emergencies, peak demand periods and plant outage seasons. It’s also used to provide a backup or second power source for critical facilities. Additionally, mobile power can back-feed customers during planned work to shorten outages.

What is a temporary substation used for?

A temporary substation steps voltage up or down and distributes power while a permanent substation is being built, upgraded, maintained or repaired after a failure. It lets utilities keep customers energized during work instead of scheduling extended outages. Temporary substation setups typically combine step-up or step-down transformers and switchgear or distribution equipment sized to the load. Learn how to assess a temporary substation solution.

What is a generator load bank test, and why is it important?

A generator load bank test uses a load bank to apply a controlled electrical load to a generator, simulating real-world demand without connecting it to the facility. The test confirms the generator can deliver its rated output and handle load changes. It also clears unburned fuel buildup (wet stacking) and reveals problems before an emergency. It’s critical for backup and emergency utility power systems that may sit idle for long periods. United Rentals offers resistive/reactive load banks for generator testing.
