Power generation for utilities

Aggreko: One stop for your utility power generation needs

How we keep power flowing to your customers

When power infrastructure faces disruption, downtime is not an option. Aggreko’s temporary and emergency power generation services ensure continuous delivery, keeping communities and businesses energized when it matters most.

Our power generation solutions cover various sectors:

Nuclear power

Maintaining safety and reliability is essential in nuclear facilities. We provide specialized temporary power solutions that meet the stringent requirements of nuclear power generation, ensuring uninterrupted operations during maintenance, upgrades, or unexpected incidents.

Fossil fuel power generation

From coal to natural gas facilities, our flexible, rapid-response backup power systems minimize downtime and maintain grid stability during planned or unexpected outages.

Renewable Energy Solutions

As the energy landscape evolves, we provide targeted support across renewable technologies:

Solar Installations: Temporary power bridges to ensure continuous energy supply
Battery Storage: Supporting grid stability and energy storage infrastructure
Electric Vehicle Charging: Temporary power solutions for EV charging networks

Whether you’re managing a nuclear facility, a fossil fuel plant, or a cutting-edge renewable energy installation, Aggreko ensures your power generation remains resilient, responsive, and reliable.

Keeping your operations energized through any challenge

Utilities face significant seasonal challenges throughout the year. In summer, extreme heat reduces cooling efficiency and generation capacity; in winter, freezing conditions strain equipment, limit fuel availability, and increase the risk of system failures. Our solutions help you navigate these temperature-driven constraints and maintain reliable power delivery in any season. Because utilities must provide consistent service year-round, even temporary system limitations can impact your ability to meet critical demand.

Our targeted supplemental cooling and power generation support ensures you can continue operations at peak performance.

We offer tailored support to help you:

Maintain full power generation
Meet contractual power delivery requirements
Prevent unexpected system downtime
Optimize performance during peak demand periods

We address your most challenging power generation constraints, keeping your operations moving when it matters most.

Supplemental cooling

Environmental compliance is critical for utility operations.

Our innovative cooling solutions help you meet stringent EPA requirements while maintaining optimal plant performance. Many plants struggle to meet EPA-mandated thermal limits, risking potential fines, operational shutdowns, or regulatory penalties.

When thermal discharge limits threaten your operational capabilities, our supplemental cooling systems offer a precise, flexible response. We also provide backup power to auxiliary systems, enabling seamless plant maintenance and outage management.

Our supplemental cooling systems ensure you maintain continuous operations and meet environmental standards.

Supplemental power

High ambient temperatures can significantly impact power generation output. As cooling efficiency decreases and equipment operates under elevated thermal stress, many plants experience measurable drops in available capacity—for example, a unit producing 900 megawatts in cooler conditions may deliver closer to 800 megawatts during periods of extreme heat. These fluctuations create operational constraints that must be managed to maintain reliable delivery.

Our supplemental cooling technologies enable you to:

Restore full generation capacity
Maintain consistent megawatt output year-round
Cool your systems more efficiently
Maximize seasonal power generation potential

By providing both supplemental cooling and power support, we help you overcome thermal performance challenges, ensuring you can meet your operational targets and regulatory obligations year-round, regardless of environmental conditions.

Frequently asked questions

Supplemental cooling refers to the use of temporary, engineered cooling systems that assist or temporarily replace a plant’s built-in heat rejection infrastructure.

These systems are particularly important when plants face thermal discharge constraints or increased load during extreme weather. By deploying mobile chillers, cooling towers, or closed-loop systems, utility companies can stay within EPA-regulated thermal limits, avoid penalties, and maintain production even when environmental conditions would normally force them to reduce output.

Utilities can maintain reliable energy generation during infrastructure outages by deploying temporary energy solutions that act as stand-ins for critical systems.

These solutions often include mobile generators, temporary substations, and auxiliary energy systems that are designed to integrate with your existing infrastructure.

By planning ahead and having right-sized, efficient, suitable energy and HVAC solutions on standby, utility companies can ensure continuous service even when core assets are offline for maintenance, upgrades, or repair.

This makes it easier to meet your contractual energy delivery requirements, minimize downtime, and keep customers happy – whatever happens to your plant.

If your outage has been planned in advance, we’ll help you prepare your site and implement solutions that protect productivity and service continuity.

Our fleet of turnkey solutions – which include industrial generators, distribution panels, and battery energy storage systems (BESS) – can be deployed rapidly to supplement or temporarily replace plant output while maintenance or upgrades are underway.

We work directly with utility teams to design site-specific solutions that meet voltage, capacity, and compliance requirements.

Whether you’re running a nuclear, fossil fuel, or renewable energy plant, we help you ensure uninterrupted energy delivery, protect contractual obligations, and minimize outage timelines.

There are lots of smart ways to make power generation cleaner and more efficient without compromising on output. For example, switching to low-emission or dual-fuel generators helps cut down on CO₂ and other harmful emissions. Adding battery storage to your setup can reduce fuel use and smooth out supply during peak demand or downtime.

Plants can also boost sustainability by improving cooling efficiency, especially during hot months when performance tends to dip. Upgrading or supplementing your cooling systems helps keep things running smoothly and within environmental limits.

The key is finding the right mix of equipment and energy management to meet your goals – whether you’re trying to cut emissions, hit compliance targets, or just run a leaner operation.
