Low-emission Tier 4 Final diesel generators – EPA-compliant temporary power
Support your operations and sustainability goals with low-emission temporary power
Efficient, flexible power generation tailored to your site’s needs
As emissions regulations tighten and operational needs grow more challenging, finding the right power solution isn’t just about capacity – it’s about compliance, flexibility, and efficiency.
Aggreko’s Tier 4 Final diesel generators are engineered to help you stay ahead of regulations, reduce fuel consumption, and optimize your performance – all while delivering dependable power exactly when and where you need it most.
By choosing Aggreko for your sustainable power solutions, you can:
- Comply confidently with EPA Tier 4 Final regulations, ideal in strict-emission zones like California and New York
- Reduce NOx and particulate emissions by 96-99% with environmentally friendly generators
- Harness load on demand and rightsizing strategies to adapt to your actual power demands and reduce costs
- Improve reliability with effective redundancy and 24/7 monitoring
- Receive power solutions and support fast – wherever your project is
Tier 4F power solutions built for performance and flexibility
- Largest fleet of Tier 4F generators in North America, with capacities from 25kW to 1,200kW, providing mobile, rapidly deployed power for any project type and scope – from remote settings like offshore rigs, to urban sites and strict air-permit environments.
- Rightsizing strategies to align your power package with the scope of your project, avoiding over-specification and disruptions from equipment failures. Load on demand means you can utilize smaller generators that automatically power up or power down to match your needs – reducing fuel consumption, emissions, and maintenance interruptions.
- Modular, specially engineered design of our Tier 4F generators to easily integrate into hybrid power packages like our battery energy storage systems (BESS), offering sustainable, cost-effective backup power, even when loads frequently fluctuate.
- Low-noise, low-emission diesel generators with improved technology designed to reduce NOx and particulate matter by up to 99%.
- Aggreko Remote Monitoring (ARM) for 24/7 visibility, letting you optimize, control, and manage your on-hire fleet with ease – whether you’re on-site or working remotely.
Aggreko’s Greener Approach: Powering the next steps to a more sustainable future
We understand your need for reliability and efficiency from your power solutions. We also understand the pressures you’re under to achieve more sustainable operations. All while balancing time, capital expenditure, and productivity in the process.
That’s why we developed our Greener Power Packages. Part of our wider Greener Upgrades initiative, these rental packages provide an enormous range of scalable, sustainable technologies and solutions – without the CAPEX.
Not only do they improve your efficiency, they also lower your costs and cut emissions by up to 99% with cleaner-burning fuels.
Coupling up with our Tier 4F diesel generators, this initiative includes:
Modular plug-and-play batteries for a hybrid power solution that ensures you only use fuel when it’s needed, either to recharge batteries or provide supplemental power.
Clean fuels like HVO biodiesel to achieve the greenest level of temporary power.
Rightsizing support from experts who will assess your load profiles, on-peak and off-peak energy demands, and find the perfect combination of batteries and energy storage solutions. By using exactly what you need, and nothing extra, you’ll be able to save significantly on fuel and emissions.
Remote monitoring to improve the reliability of our solutions and reduce waste by proactively monitoring for uptime, performance and early fault detection.

Frequently Asked Questions
The main difference between Tier 3 and Tier 4 engines lies in their emissions standards.
Tier 4 engines, including Aggreko’s Tier 4 Final diesel generators, are designed to meet stricter Environmental Protection Agency (EPA) regulations for diesel engines, reducing harmful pollutants like nitrogen oxides (NOx) and particulate matter by up to 99% compared to Tier 3 models. This makes Tier 4 engines a superior choice for projects in environmentally sensitive areas where compliance and sustainability are key.
‘Tier 4 Interim’ and ‘Tier 4 Final’ refer to different phases of the EPA’s emissions regulations.
Tier 4 Interim engines reduced emissions compared to previous standards, but were a transitional step. Tier 4 Final engines, like those in Aggreko’s fleet, meet the strictest emissions limits, cutting NOx and particulate matter emissions by up to 99%, making them ideal for projects in areas with stringent environmental regulations.
Aggreko offers a wide range of Tier 4 Final diesel generators ranging from 25 kW to 1,200 kW, designed for flexible deployment across industrial, commercial, and urban projects. Our EPA-compliant generators deliver reliable, low-emission power wherever you need it. Their modular design allows them to integrate easily into hybrid systems, enhancing both performance and sustainability.
Using Aggreko’s Tier 4F-compliant generators offers many far-reaching benefits:
- Up to 99% reductions in NOx and particulate matter emissions, supporting greener operations through our Greener Upgrades initiative
- Full EPA compliance, making them suitable for use in the strictest emissions zones
- Lower noise levels, ideal for urban and noise-sensitive environments
- Flexibility through modular, scalable design for a wide range of applications
- Easy integration with battery energy storage systems (BESS) for greener power solutions that reduce fuel consumption and emissions
