#Colorado ’s biggest #datacenter wants to add another 98 #diesel backup generators
By Sam Brasch
Jul. 8, 2026"On the eastern edge of #AuroraCO, #QTS , a leading data center developer, is rapidly transforming a 65-acre property south of #DenverInternationalAirport.
"One of three massive data centers is already complete, a second appears nearly finished and heavy machinery is now prepping a footprint for the third. On a recent afternoon, the low rumble of construction nearly drowned out chirps from #PrairieDogs burrowed into the surrounding #grasslands.
"Once completed, the campus will require at least #160MW, about four times the peak capacity of the international airport nearby. QTS also promises around-the-clock service for future customers. To keep the facility humming through blackouts, it plans to add 98 diesel backup generators to its fleet of 40 hulking engines already installed at the Aurora campus, according to a permit application submitted to state regulators in July 2025.
"It’s a backup system fit for Colorado’s largest data center, the state’s only #hyperscale facility larger than #100MW. Each engine is a small power plant the size of a semitruck, but roughly seven times more powerful. Once installed, the generators will release sporadic bursts of intense #sound and #DieselExhaust, containing #pollutants like #ParticulateMatter and #NitrogenOxides, a key ingredient behind Colorado’s #SummertimeOzone struggles.
"Data center critics worry that similar projects could be close behind. Alana Miller, the Colorado policy director for the Natural Resources Defense Council [ #NRDC ], said the prospect is why her organization helped lead a failed push to regulate data centers in the last legislative session. If passed, the bill would have required data centers to supply their own #RenewableEnergy, tightened pollution standards for backup systems and required additional input for projects in historically polluted neighborhoods.
" 'The QTS Aurora expansion is a perfect example of why Colorado needs strong statewide data center guardrails,' Miller said. 'Aurora is already in severe ozone nonattainment, and left unchecked, new diesel generators could make the problem worse.'
" #DieselGenerators are a growing concern in data center hotspots like northern #Virginia.
"A recent analysis by the Washington Post examined air permits for more than 132 data centers packed into the region. It found generators at the facilities represent a significant health risk — even if they’re rarely used. With more than 10,000 generators attached to Virginia data centers, even operating them less than an average of an hour per week would carry roughly the same public health impact as five large gas-fired power plants, according to the report.
"Another study by the University of California Riverside and Caltech estimates data center #AirPollution could result in as many as 1,300 premature deaths every year by 2030. That research, however, is still undergoing peer review."

'Dangerous' air quality in Detroit, Minneapolis as thick wildfire smoke shrouds the sky for millions
Smoke from wildfires burning in Ontario have caused air quality to reach "dangerous" levels across Canada, and the northeastern and midwestern United States. And it could get worse before conditions improve.
By Brian Lada, AccuWeather meteorologist
Published Jul 15, 2026 11:50 AM EDT | Updated Jul 16, 2026
" Massive plumes of smoke are descending across parts of Canada and the United States, creating dangerous air quality and scenes reminiscent of the historic wildfire smoke outbreak from three summers ago.
" 'In 2023, a major fire outbreak in Quebec caused days of unhealthy air quality in the northeastern U.S.,' AccuWeather Vice President of Forecast Operations Dan DePodwin said. 'This event could cause similar levels of poor air quality in spots.'
"Air quality alerts have been issued for millions of people, including across all of #Connecticut, #Delaware, #Massachusetts, #Michigan, #NewHampshire, #NewJersey, #NewYork, #Ohio, #Pennsylvania, #RhodeIsland and #Wisconsin.
"Over 800 wildfires are currently burning across Canada, including dozens that are out of control across western #Ontario, the source of most of the smoke. 'Many of these fires may have been started by lightning,' AccuWeather Senior Meteorologist Brett Anderson said.
"On Wednesday, #Toronto had some of the worst air quality in North America, reaching 'very unhealthy' levels with an AQI of 220. #BostonMA was not far behind with an unhealthy AQI of 147.
" 'When the AQI climbs into the 150+ range for a full day outside, that’s in the ballpark of [smoking] 7 to 9 cigarettes,' Dr. Jonathan M. Tan, division chief of General Anesthesiology at Children’s Hospital of Philadelphia, told AccuWeather.
"Conditions deteriorated by Thursday morning, with widespread "dangerous" air quality across nearly all the Great Lakes region and into parts of the Northeast. Minneapolis and Duluth, Minnesota, as well as Detroit, were among the worst cities at daybreak Thursday, with AQIs over 340.
" 'Any exposure to the air, even for a few minutes, can lead to serious health effects on everybody,' Plume Labs said.

Canadian #wildfire smoke turns air hazardous in the US #Midwest. Officials say stay inside
By TAMMY WEBBER and PHILIP MARCELO, July 16, 2026
NEW YORK (AP) — "Heavy, pungent smoke from #CanadianWildfires darkened skies in the U.S. on Thursday from the #GreatLakes to parts of the #EastCoast, reducing visibility for commuters and prompting warnings that air quality could make being outside dangerous.
"#Detroit’s air quality was among the worst in the world for major cities, as a lingering high pressure system trapped smoke from dozens of fires in Canada and northern Minnesota, said Steven Freitag, a National Weather Service meteorologist in Pontiac, Michigan.
" 'Sure enough, it arrived in force here and it’s really pretty extreme levels,' said Freitag, who noted that visibility in some areas was reduced to a half mile.
"Omar Mitchell wore a mask as he walked to his restaurant in Detroit. He said he urged his employees to do the same.
" 'It’s scary,' Mitchell, 50, said as he looked at the sky. 'You don’t know necessarily what the side effects may be. That’s days or months later.'
"Cities across the Great Lakes states registered air quality ranging from unhealthy to hazardous — which means it’s unhealthy for anyone, regardless of health conditions. Microscopic particles can lodge deep in the lungs and enter the bloodstream, leading to heart and lung problems and contributing to other long-term health issues.
"All of #Michigan and much of #Minnesota were under a hazardous #AirQualityAlert. In the Chicago area, air quality ranged from very unhealthy to hazardous.
"National Weather Service meteorologist Jake Petr said even if winds from the northwest clear skies as expected later this week, the smoky air could keep returning until the fires are out. That could take weeks or longer.
" 'Anytime we have something that could bring air from that region until the fires are over, it could conceivably dip back into the area,' Petr said.
"In #SaintPaulMN, the air was 'glowing yellow,' said Brent Williams, head of the soil, water and climate department at the University of Minnesota, who said the area 'could be looking at weeks to months of continued smoke and flare-ups off and on as the winds blow in different directions.'
"A study published this year found that long-term exposure to tiny particles from wildfire smoke contributed to an average of 24,100 deaths a year in the lower 48 states. Long-term exposure can make existing health problems worse and lead to a range of chronic and deadly health issues, including respiratory illness, cardiovascular and neurological diseases, and premature death."

Canadian #wildfire smoke turns air hazardous in the US #Midwest. Officials say stay inside
By TAMMY WEBBER and PHILIP MARCELO, July 16, 2026
NEW YORK (AP) — "Heavy, pungent smoke from #CanadianWildfires darkened skies in the U.S. on Thursday from the #GreatLakes to parts of the #EastCoast, reducing visibility for commuters and prompting warnings that air quality could make being outside dangerous.
"#Detroit’s air quality was among the worst in the world for major cities, as a lingering high pressure system trapped smoke from dozens of fires in Canada and northern Minnesota, said Steven Freitag, a National Weather Service meteorologist in Pontiac, Michigan.
" 'Sure enough, it arrived in force here and it’s really pretty extreme levels,' said Freitag, who noted that visibility in some areas was reduced to a half mile.
"Omar Mitchell wore a mask as he walked to his restaurant in Detroit. He said he urged his employees to do the same.
" 'It’s scary,' Mitchell, 50, said as he looked at the sky. 'You don’t know necessarily what the side effects may be. That’s days or months later.'
"Cities across the Great Lakes states registered air quality ranging from unhealthy to hazardous — which means it’s unhealthy for anyone, regardless of health conditions. Microscopic particles can lodge deep in the lungs and enter the bloodstream, leading to heart and lung problems and contributing to other long-term health issues.
"All of #Michigan and much of #Minnesota were under a hazardous #AirQualityAlert. In the Chicago area, air quality ranged from very unhealthy to hazardous.
"National Weather Service meteorologist Jake Petr said even if winds from the northwest clear skies as expected later this week, the smoky air could keep returning until the fires are out. That could take weeks or longer.
" 'Anytime we have something that could bring air from that region until the fires are over, it could conceivably dip back into the area,' Petr said.
"In #SaintPaulMN, the air was 'glowing yellow,' said Brent Williams, head of the soil, water and climate department at the University of Minnesota, who said the area 'could be looking at weeks to months of continued smoke and flare-ups off and on as the winds blow in different directions.'
"A study published this year found that long-term exposure to tiny particles from wildfire smoke contributed to an average of 24,100 deaths a year in the lower 48 states.
