PEC requested the air permits for all of the approximately hundred data center facilities covered under the proposed DEQ variance, including the number of commercial generators per facility. We determined that there are 4,632 commercial diesel generators in total and that these generators have a total capacity of 11.1 gigawatts of power. Our web map displays the data centers locations, as well as nearby schools, nursing homes and low income communities.
