Microsoft wants to add 72 generators at data center

QUINCY – Microsoft wants to add 72 emergency backup generators at its Quincy data center, and the Washington Department of Ecology is accepting comments through Aug. 31 on the proposal.

Additional generators require an updated air quality permit to help protect people and the environment, Ecology said in a news release. The updated permit also includes 136 cooling towers.

Powered by diesel engines, backup generators keep servers functioning during a power outage. The engine exhaust releases pollutants like carbon monoxide, nitrous oxide and volatile organic compounds, which can cause health problems for people exposed frequently and at high enough levels.

However, Ecology said the data center will meet health criteria if operated according to the permit.

To review the permit, visit bit.ly/2v3G99C, Quincy City Hall at 115 First Ave. SW, or the Quincy Library at 208 Central Ave. S.

A public hearing is set for 5 p.m. Aug. 27 at the Quincy Community Center, 115 F St. SW.
