DOC Upgrade: Adding Flexibility and Savings

A customer had initially worked with IEA to install an emergency-only diesel generator to protect its data center. This prevented them from preemptively running the engine in order to protect from weather conditions, utility outages, and maintenance. One year later a proposal from the company was brought to IEA to convert the engine to a non-emergency standby generator.

IEA directly helped the company to submit the new environmental permitting and sourcing the required equipment for construction on site. The required permitting changes to enable it to move from emergency only to non-emergency through a synthetic minor PSD permit. This allowed the company to benefit from the engine, by supporting the local utility interruptible program, and taking advantage of the savings afforded to it.

Since the unit was manufactured and in service prior to July of 2006, the unit could be upgraded to add a Diesel Oxidizing Catalytic (DOC) filter to meet the RICE NESHAP requirements of USEPA regulation 40CFR63 Subpart ZZZZ.

The customer opted to have a stainless steel outer enclosure placed around the DOC for aesthetic purposes. The project took only a couple of days to install.
