Load bank rental and power system accessories
We provide load testing solutions of all sizes, voltages, and capacities for any industrial application. Wherever you need to preserve productivity, efficiency and safety, our load banks are tried and tested.
Comprehensive load testing helps you get ahead of potential issues, validate performance, and feel confident that generators are ready to perform when you need them. But effective load testing requires carefully engineered solutions where your load bank is adapted to your environment, energy infrastructure, and other equipment.
At Aggreko, we combine the widest range of load banks with decades of engineering experience. Our load bank rental services provide accurate, reliable electrical test loads for commissioning your systems and for preventative maintenance. Across resistive, resistive and reactive, capacitive, and DC load banks, we’ll design and deliver a rightsized solution so you can:
- Use a load bank for generator testing that matches the full capacity and recommended load of your energy source
- Simulate a real-time load in isolation, without affecting your other systems
- Avoid wet-stacking by maintaining a manufacturer’s recommended load level
- Meet regulations including the need for transient testing and block loading
- Identify potential issues earlier and maximize the reliability of your equipment
Load banks designed to increase your agility
Our comprehensive fleet of load banks is carefully balanced to cover the widest possible range of applications, load types, and voltages.
Supporting a range of load bank applications
- Meet regulations and legal requirements that call for regular load testing across your equipment. When regulations call for specific load profiles and durations, we’ll provide a turnkey solution complete with sophisticated handheld controls and detailed data capture for reporting and auditing.
- Test your emergency and backup energy systems by simulating how they perform, even when they’re required to start on load. We’ll help you increase reliability and get peace of mind so that you can maintain continuity, even in an emergency.
- Identify maintenance issues including degrading insulation by testing equipment and benchmarking performance against known baselines or manufacturer expectations. These tests can alert you to the need for preventative maintenance.
- Avoid wet-stacking and carbon buildup in generators by using a load bank to determine capabilities and output. A load bank rental can also be used to provide load that clears out known carbon buildup in an engine.
- Simulate performance at peak demand safely and accurately. Our load banks can all be used individually or work together in parallel, so you can test at scale and understand how equipment performs in these conditions.
- Meet schedules and performance expectations by thoroughly testing your equipment earlier in the process.

Frequently Asked Questions
A load bank is a self-contained electrical device used to apply a controlled, simulated load to a power source—such as a generator, UPS (uninterruptible power supply), or battery system. It mimics real-world electrical demand, allowing operators to safely test the capacity, performance, and reliability of critical power systems under controlled conditions.
Load bank testing is essential for:
- Verifying system functionality during commissioning
- Conducting routine maintenance to prevent failures
- Ensuring power sources are properly sized for peak demand
- Supporting compliance with industry and safety standards
Regular testing helps identify issues before they lead to downtime, extending equipment life and improving operational resilience.
Aggreko’s load banks are built with advanced digital control systems, enabling:
- Gradual or step-based load application for safe and precise simulation
- Real-time monitoring of key parameters: voltage, current, frequency, power factor
- Accurate replication of real-world conditions, including peak loads and transient events
This level of control allows engineers to diagnose inefficiencies, verify system performance, and meet compliance standards with confidence—helping prevent critical failures in the field.
Yes, Aggreko offers flexible load bank rental services. Whether you need a load bank for a one-time test or an extended period, Aggreko provides both short-term and long-term rental options. This allows you to access state-of-the-art load testing equipment without having to invest in purchasing expensive units.
Aggreko also offers logistical support, delivering load banks to your site and assisting with setup, so you can conduct your testing efficiently without worrying about transport or installation. Renting from Aggreko means you receive high-performance equipment and expert guidance, without the long-term cost of ownership.
Yes. Aggreko load banks are designed for maximum flexibility—whether you're testing a 100 kW backup generator or a multi-megawatt utility-grade system.
- Modular design enables load scaling for larger or multi-phase applications
- Customizable configurations support complex testing scenarios, including power factor correction or renewable integration
- Available in multiple voltage ranges, ideal for site-specific requirements
Yes — Aggreko offers end-to-end load bank testing solutions, not just equipment rentals. We provide:
- On-site setup and integration with your power system
- Certified technicians to run step tests and configure equipment
- Live monitoring and data logging throughout the test
- Post-test reports with insights and expert recommendations
Our service supports a range of industries — including data centers, manufacturing, healthcare, utilities, and construction. Whether you're commissioning new equipment or validating backup power systems, Aggreko ensures accurate, safe, and compliant testing.
For teams without in-house expertise, we simplify the process and support any post-test adjustments to keep your systems running reliably.
Yes, matching your load bank’s voltage rating to your power source is essential. Most load banks are designed for a specific nominal voltage, like 480V. Using a higher voltage can cause overheating and equipment damage, while a lower voltage will reduce the available load.
For safe, reliable testing, always confirm the load bank matches your power system. Aggreko’s team of experts can help you choose the right setup for your project.
Yes, Aggreko offers both indoor and outdoor load banks to meet the needs of different environments.
- Indoor load banks are designed to deliver reliable load testing in protected environments and use non-insulated resistors. While they operate similarly to outdoor units, they are not built to withstand exposure to weather or harsh conditions.
- Outdoor load banks, on the other hand, are built with insulated resistors and housed in weatherproof enclosures. They are engineered to perform reliably even in challenging conditions like rain, dust, and extreme temperatures.
Aggreko can help you choose the right load bank based on your project environment to ensure safe, effective, and accurate testing.
