Allowing Data Center Emergency Diesel Generators to Run More Often
 

Given the high density of data centers in Prince William and Loudoun Counties and their close proximity to homes and schools, the idea of running such a high number of dirty and hazardous Tier II diesel generators even longer is frightening.  To make things worse, the number of data centers planned continues to grow.  If utilities want the flexibility for the data centers to be able to run their existing backup diesel generators during planned outage events they simply need to bite the bullet and add SCRs (selective catalytic reduction systems) to protect the public from pollution.  They are no different than VW that had to improve their diesel cars at great expense to protect the public.

Thank you
