The good news is that some generators can be upgraded to meet the EPA’s new requirements, and given how strong DR markets are right now, the ROI on these upgrade projects make the effort worthwhile. Our four-step process provides an overview of what’s involved from start to finish.
Step 1: Determine Whether Your Diesel Generator is Compliant
Not all non-compliant generators can be upgraded, and some generators don’t need to be upgraded to be compliant. So, as a first step, we’ll want to figure out which compliance category your generator falls into.
Compliance standards can be pretty complex, and NESHAP is no different. But to get you started, if you can answer “yes” to these two questions about your diesel generator’s engine, chances are quite good that it is not compliant but can be upgraded.
Is the generator engine larger than 225 kW or 300 hp?
Did you order it (or was it manufactured) before April 1, 2006?
If you have a natural gas generator, or answered “no” to any of the above, get in touch and we’ll talk it through.
Step 2: Define the Project Scope of Work
Once you’ve determined that your generator engine is upgradable, typically you will need to install a diesel oxidation catalyst (DOC) to reduce carbon emissions by at least 70%. Additionally, you’ll need a monitoring system on the DOC, crankcase ventilation, and will need to complete some stack testing and reporting.
Some cities, counties, and states have their own air regulations, and you will need to comply with those if they are more rigid than the EPA’s air regulations.
Step 3: Gather Project Cost Estimates
There are many vendors that can upgrade your generator. We are vendor-agnostic, and can help you gather and review project cost estimates to make sure everything that’s needed for compliance has been included.
The cost to upgrade your generator will depend on variables at your site. For example, you’ll need to ask:
How accessible is your generator?
Are additional structural supports necessary for the DOC?
Will installation need to occur during off hours?
Depending on the answers to these and other questions, project costs range from $40K to $80K per engine.
Then, based on the kW loaded on your generator and the DR programs available in your area, we’ll prepare a DR earnings estimate so you can consider the project ROI.
Don’t have $40K to $80K to commit? No problem. Enel X offers project financing so you can upgrade your generators with no upfront cost.
Step 4: Complete the Upgrade Project, Reduce your Carbon Footprint, and Start Earning!
A generator upgrade project can take anywhere from three to six months, beginning with gathering cost estimates and continuing through to final installation and testing. The actual on-site work typically takes only a few days, but the installation needs to be fully complete prior to the start of the DR program season so you can start earning right away.
