E&E News by POLITICO reports that residents living near data centers are expressing alarm about diesel generator emissions during heat waves, when facilities run backup power systems for extended periods to maintain cooling and uptime. Community members in multiple states described the pollution as a health threat, with one resident quoted saying 'we are screwed.' The story highlights that generator runtime during extreme heat events is largely unregulated at the federal level.
Diesel generator emissions from data centers during heat waves represent a documented air quality impact that has received little regulatory attention compared to water use or grid demand. If federal or state agencies move to regulate extended generator runtime, it could materially affect data center operating costs and emergency power planning.
