If you have a microgrid at your facility or are looking for emergency backup generators, you’ll want to invest in Tier 4 Final Diesel Generators. Facilities that rely on lower-tier generators generate more emissions and will use fuel less efficiently, leading to higher costs. As you try to optimize on-site power at your facility, find out more about why Tier 4 diesel generators can provide several benefits and how to choose the right ones for your facility.

What Are Tier 4 Final Certified Generators?

Tier 4 Final generators are diesel engine generators that meet the EPA’s latest emissions requirements for air toxics, oxides of Nitrogen (NOx), and particulate matter (PM) produced by new, non-road diesel engines. Tier 4 generators must comply with the EPA’s New Source Performance Standards (NSPS). These standards set the acceptable levels of emissions that large stationary generator sets can create.

A certified Tier 4 generator will meet EPA low emission standards, helping to avoid costly penalties. They’re also optimized for greater fuel efficiency to create significant economic value. Due to these advantages, they’re often included in microgrids to provide cleaner energy and keep fuel costs low.

What’s the Difference Between an Interim and Tier 4 Final Certified Generator?

While you look for a Tier 4 diesel generator, it’s important to select a Tier 4 Final certified generator versus a Tier 4 interim generator. Tier 4 interim generators are earlier models that met NSPS emissions standards that became effective at the start of 2011. While these generators significantly reduced NOx emissions and improved their operational flexibility, they aren’t as effective as Tier 4 Final certified generators.

Unlike a Tier 4 interim, a Tier 4 Final generator meets NSPS emissions standards that went into effect in 2015. Due to their meeting of these new requirements, Tier 4 Final generators offer both reduced NOx and PM emissions.

What’s the Difference Between Compliant and Certified Tier 4 Generators?

Another distinction you’ll need to know when selecting a Tier 4 Generator is whether it’s a compliant or certified generator. Complaint generators are EPA-certified stationary emergency engines featuring third-party after-treatment equipment designed to reduce emissions. Certified Tier 4 generators are EPA-certified, with testing completed at the engine manufacturer’s facility, and they can be used in non-emergency situations.

If you plan to use your generator for non-emergency purposes, you’ll want to select a certified Tier 4 generator. Compliant Tier 4 generators can only be used in emergency situations. For example, facilities with microgrids that provide power during non-emergency situations will need to use a certified Tier 4 Final generator.

How to Choose a Tier 4 Final Certified Generator

When you’re searching for a Tier 4 Final certified generator for emergency use or your facility’s microgrid, you’ll want to turn to an expert for assistance. Since you can find a wide variety of Tier 4 generator sets from a variety of brands, a microgrid expert can walk you through the best available certified generators and select those that will fit your goals for your microgrid or emergency backup needs.
