Temporary Power Solutions for Critical Applications

Unexpected outages, critical maintenance or projects in remote locations all pose a direct challenge to operational continuity. Every moment without reliable power disrupts even the best-planned schedules. You need the ability to restore or supplement power promptly to keep people, processes and assets secure and productive.

Sunbelt Solomon provides a proven way to quickly and safely bridge power gaps, renting mobile substations alongside our comprehensive power solutions.

Temporary Power Solutions for Critical Applications​

Our nationwide fleet of rental mobile substations provides reliable, rapid-response solutions when power interruptions threaten essential operations. From sudden outages and planned maintenance to grid upgrades and temporary projects, these emergency substation rental units can connect to grids or sites operating at up to 230 kV and deliver up to 50,000 kVA of electrical power, depending on configuration — enough for large-scale, demanding applications.

The pre-engineered, rapid deployment design is ideal for field operations and other environments where a stationary substation can’t be installed in time. Plus, each Sunbelt Solomon portable substation comes with more than just a transformer. Our fleet of reconditioned and rigorously tested mobile units commonly includes:

  • High- and medium-voltage switchgear.
  • Protection and control equipment to safeguard your assets and manage power flow.
  • Auxiliary systems such as AC/DC power supplies, communications and monitoring equipment.
  • Additional features as needed, including circuit breakers, metering and cabling.
  • Trailer-mounted substation configurations.

Beyond equipment, Sunbelt Solomon provides turnkey support throughout the rental process, so you can address your urgent power needs without coordinating with multiple vendors.

More Than a Rental

Sunbelt Solomon stands as a full-lifecycle power partner, offering support that extends well beyond short-term equipment needs. Along with our fleet of rentals and mobile power transformers, our one-stop shop spans the entire spectrum of transformer and substation requirements, including:
