Auxiliary power refers to the backup energy solutions that keep essential processes running when your primary power source is unavailable. For utility providers, having reliable auxiliary power units helps avoid service disruptions, maintain critical functions, and protect grid stability during maintenance, outages, or emergencies.

These backup energy solutions are essential for ensuring uninterrupted energy supply during unplanned outages, natural disasters, extreme weather, or scheduled maintenance.

Without reliable standby power solutions or auxiliary power units, utility providers risk unplanned downtime, regulatory penalties, and leaving customers without energy. In extreme cases, outages can damage infrastructure or disrupt grid stability. Aggreko’s auxiliary power solutions help minimize these risks by keeping essential operations running smoothly during unexpected events.

At Aggreko, we provide a wide range of temporary energy solutions ideal for utilities, including mobile power generation units, backup generators, rental solutions, and battery energy storage systems (BESS). These can be easily scaled to meet different energy demands, and paired with transformers, switchgear, and distribution panels for full-site energy support.

Aggreko supports utility companies with emergency auxiliary power solutions that balance performance with sustainability. By integrating hybrid generators, battery storage, and real-time monitoring, Aggreko helps reduce fuel consumption, lower emissions, and ensure efficient energy use - even during outages or peak demand.

Mobile backup generators provide flexibility, fast deployment, and cost control during power disruptions. For utilities, Aggreko’s backup energy solutions can be rapidly deployed to restore critical systems and maintain compliance, while integrated monitoring through Aggreko Remote Monitoring (ARM) tracks fuel use to make sure rental equipment is running at peak operational efficiency.
