Substation Power

Substation Solutions for Maintenance, Emergencies, and Grid Stability

We partner with transmission and distribution firms to reduce the risk of downtime, support substation commissioning, and conduct vital maintenance

Substations are a critical part of the energy infrastructure, transforming and regulating voltages to feed energy to residential and commercial users. When a substation is offline—whether due to maintenance, upgrades, or unplanned issues—the impact on customers is immediate.

At Aggreko, we provide comprehensive temporary power and electrical support for substation work, using our scalable fleet of generators, transformers, distribution equipment, and load banks. We help you:

  • Reduce customer minutes of interruption and meet service expectations
  • Bridge substation outages with temporary power and transformer solutions
  • Maintain customer service during planned maintenance or equipment replacements
  • Scale temporary power or supplemental transformers to support peak demand or system constraints
  • Test and energize new substations with load bank and commissioning support
  • Provide ongoing support during routine maintenance and upgrades
Why rely on us for substation solutions?

Our deep understanding of utility operations and critical infrastructure allows us to engineer temporary solutions that keep your system stable, energized, and protected.

  • Fast-deploy engineered systems — We combine deep utility expertise with engineered temporary solutions that keep power flowing and protect grid performance.
  • Transmission and distribution expertise — Decades of work alongside transmission and distribution teams guide how we design safe, reliable temporary configurations.
  • Scalable, flexible support — Whether you need added capacity, temporary backfeed support, or commissioning assistance, our solutions scale to meet your operational demands.
  • Sustainable options — We offer hybrid, alternative-fuel, and efficiency-driven options to help reduce emissions while maintaining reliability.
Supporting every corner of your utility operation

From planned upgrades to unplanned emergencies, we deliver cooling, dehumidification, and energy solutions that keep utility operations running safely and efficiently – no matter the challenge.

Temporary solutions that keep your substation online

Keep your customers energized with our temporary power, cooling, and electrical distribution solutions. We deliver the generators, transformers, distribution panels, and load banks needed to build out temporary substation support and maintain continuity when parts of your system are offline.

Respond quickly to substation emergencies with our extensive fleet of generators, high-voltage transformers, and temporary distribution equipment. We help you maintain service, reduce interruption minutes, and keep critical loads energized during unplanned events.

Commission new substations with confidence using our load banks and temporary power setups. From energization to load testing, we provide the equipment and expertise needed to validate performance and meet your in-service dates.

01

Aggreko designs temporary power solutions that support load transfer and keep customers energized when substation components are taken offline. Our teams model your system requirements, plan the switching sequence, and build a safe temporary configuration that maintains continuity and minimizes customer interruptions during maintenance or upgrades.
02

For commissioning, Aggreko provides engineered testing setups that replicate real operating conditions. We design load bank applications and temporary power arrangements that help validate equipment performance, verify protection settings, and support energization sequences, ensuring the substation is ready for safe, reliable operation before going live.
03

Aggreko develops engineered support strategies that stabilize the system when substation capacity is limited. By analyzing loading, voltage needs, and risk points, our teams create temporary configurations that maintain voltage levels, protect critical loads, and relieve strain on the grid during outages, constraints, or peak demand.
