When powerful wind gusts created threatening wildfire conditions one day near Boulder, Colorado, the state’s largest utility cut power to 52,000 homes and businesses — including Frasier, an assisted living and skilled nursing facility.
It was the first time Xcel Energy preemptively switched off electricity in Colorado as a wildfire prevention tool, according to a company official. The practice, also known as public safety power shut-offs, has taken root in California and is spreading elsewhere as a way to keep downed and damaged power lines from sparking blazes and fueling the West’s more frequent and intense wildfires.
In Boulder, Frasier staff and residents heard about the planned outage from news reports. A Frasier official called the utility to confirm and was initially told the home’s power would not be affected. The utility then called back to say the home’s power would be cut, after all, said Tomas Mendez, Frasier’s vice president of operations. The home had just 75 minutes before Xcel Energy shut off the lights on April 6.
Staff rushed to prepare the 20-acre campus home to nearly 500 residents. Generators kept running the oxygen machines, most refrigerators and freezers, hallway lights, and Wi-Fi for phones and computers. But the heating system and some lights stayed off as the overnight temperature dipped into the 30s.
Power was restored to Frasier after 28 hours. During the shut-off, staff tended to nursing home and assisted living residents, many with dementia, Mendez said.
“These are the folks that depend on us for everything: meals, care, and medications,” he said.
Not knowing when power would be restored, even 24 hours into the crisis, was stressful and expensive, including the next-day cost of refilling fuel for two generators, Mendez said.
“We’re lucky we didn’t have any injuries or anything major, but it is likely these could happen when there are power outages — expected or unexpected. And that puts everyone at risk,” Mendez said.
As preemptive power cuts become more widespread, nursing homes are being forced to evaluate their preparedness. But it shouldn’t be up to the facilities alone, according to industry officials and academics: Better communication between utilities and nursing homes, and including the facilities in regional disaster preparedness plans, is critical to keep residents safe.
“We need to prioritize these folks so that when the power does go out, they get to the front of the line to restore their power accordingly,” said David Dosa, chief of geriatrics and professor of medicine at UMass Chan Medical School in Worcester, Massachusetts, of nursing home residents.
Restoring power to hospitals and nursing homes was a priority throughout the windstorm, wrote Xcel Energy spokesperson Tyler Bryant in an email. But, he acknowledged, public safety power shut-offs can improve, and the utility will work with community partners and the Colorado Public Utilities Commission to help health facilities prepare for extended power outages in the future.
When the forecast called for wind gusts of up to 100 mph on April 6, Xcel Energy implemented a public safety power shut-off. Nearly 275,000 customers were without power from the windstorm.
Officials had adapted after the Marshall Fire killed two people and destroyed or damaged more than 1,000 homes in Boulder and the neighboring communities of Louisville and Superior two and a half years ago. Two fires converged to form that blaze, and electricity from an Xcel Energy power line that detached from its pole in hurricane-force winds “was the most probable cause” of one of them.
“A preemptive shutdown is scary because you don’t really have an end in mind. They don’t tell you the duration,” said Jenny Albertson, director of quality and regulatory affairs for the Colorado Health Care Association and Center for Assisted Living.
More than half of nursing homes in the West are within 3.1 miles of an area with elevated wildfire risk, according to a study published last year. Yet, nursing homes with the greatest risk of fire danger in the Mountain West and Pacific Northwest had poorer compliance with federal emergency preparedness standards than their lower-risk counterparts.
Under federal guidelines, nursing homes must have disaster response plans that include emergency power or building evacuation. Those plans don’t necessarily include contingencies for public safety power shut-offs, which have increased in the past five years but are still relatively new. And nursing homes in the West are rushing to catch up.
In California, a more stringent law to bring emergency power in nursing homes up to code is expected by the California Association of Health Facilities to cost over $1 billion. But the state has not allocated any funding for these facilities to comply, said Corey Egel, the association’s director of public affairs. The association is asking state officials to delay implementation of the law for five years, to Jan. 1, 2029.
Most nursing homes operate on a razor’s edge in terms of federal reimbursement, Dosa said, and it’s incredibly expensive to retrofit an old building to keep up with new regulations.
Frasier’s three buildings for its 300 residents in independent living apartments each have their own generators, in addition to two generators for assisted living and skilled nursing, but none is hooked up to emergency air conditioning or heat because those systems require too much energy.
Keeping residents warm during a minus-10-degree night or cool during two 90-degree days in Boulder “are the kinds of things we need to think about as we consider a future with preemptive power outages,” Mendez said.
Federal audits of emergency preparedness at nursing homes in California and Colorado found facilities lacking. In Colorado, eight of 20 nursing homes had deficiencies related to emergency supplies and power, according to the report. These included three nursing homes without plans for alternate energy sources like generators and four nursing homes without documentation showing generators had been properly tested, maintained, and inspected.
For Debra Saliba, director of UCLA’s Anna and Harry Borun Center for Gerontological Research, making sure nursing homes are part of emergency response plans could help them respond effectively to any kind of power outage. Her study of nursing homes after a magnitude 6.7 earthquake that shook the Los Angeles area in 1994 motivated LA County to integrate nursing homes into community disaster plans and drills.
Too often, nursing homes are forgotten during emergencies because they are not seen by government agencies or utilities as health care facilities, like hospitals or dialysis centers, Saliba added.
Albertson said she is working with hospitals and community emergency response coalitions in Colorado on disaster preparedness plans that include nursing homes. But understanding Xcel Energy’s prioritization plan for power restoration would also help her prepare, she said.
Bryant said Xcel Energy’s prioritization plan for health facilities specifies not whether their electricity will be turned off during a public safety power shut-off — but how quickly it will be restored.
Julie Soltis, Frasier’s director of communications, said the home had plenty of blankets, flashlights, and batteries during the outage. But Frasier plans to invest in headlamps for caregivers, and during a town hall meeting, independent living residents were encouraged to purchase their own backup power for mobile phones and other electronics, she said.
Soltis hopes her facility is spared during the next public safety power shut-off or at least given more time to respond.
“With weather and climate change, this is definitely not the last time this will happen,” she said.

Conservation groups in Maine are calling on the state's congressional delegation to protect federal funding for clean energy technologies.
A new report found the state has benefited from more than $2 billion in clean energy investments stemming from the Inflation Reduction Act and Bipartisan Infrastructure Law.
Jack Shapiro, climate and clean energy program director for the Natural Resources Council of Maine, said many of the programs have helped low-income and rural communities.
"From a cost saving perspective, from an energy independence perspective, from a climate perspective, this is the right path to be on," Shapiro asserted. "We hope that we continue to have federal support to do that."
Shapiro pointed out the state has received millions of additional dollars in climate resilience funding to better prepare for extreme weather events. The Trump administration is reported to be exploring ways to cancel already approved loans for clean energy and redirect those funds toward nuclear power and liquefied natural gas.
Maine has set an ambitious goal of reaching net-zero emissions by 2045 and the state has directed millions of dollars toward offshore wind energy projects, an electric vehicle charging network and electric heat pumps.
Shapiro noted all corners of the state are benefiting from energy investments, including efforts to improve electric grid reliability.
"Power outages are a frequent occurrence and that can be addressed by local energy production, like solar and local energy storage and microgrids," Shapiro outlined. "A number of these investments have gone to support those things as well."
Shapiro added federal funding has also created good-paying jobs. The state's clean energy sector grew three times faster than the state's overall economy between 2016 and 2022 and now employs more than 15,000 people. Gov. Janet Mills has set a goal of 30,000 clean energy workers by 2030.

Addressing Colorado's rising cost of living and protecting clean air and water are priorities for Democratic Representative Emily Sirota of Denver in the current legislative session.
Sirota recently introduced House Bill 1090 to regulate so-called junk fees charged by landlords.
The bill would protect tenants from getting bills that can add hundreds of dollars to their monthly rent, for things such as valet trash service, internet service, surcharges on rent payments, pest control and more.
"All sorts of additional fees are being added to folks' bill," Sirota pointed out. "We think if landlords want to charge those fees, they should be reflected in the rent."
Some see junk fees as deceptive and unfair trade practices, because landlords advertise one price to lure renters, but the price is not what they will actually have to pay. Industry groups argued fees are necessary to recoup hard costs and added out all fees are listed in black in white before tenants sign their leases.
Sirota has also introduced House Bill 1011, a measure to add guardrails as private equity firms buy up child care operations, firms already disrupting housing and health care markets.
"And really has been to the detriment of consumers in those sectors because their traditional business model is to increase prices or fees and drive down wages," Sirota observed.
The Trump administration has once again abandoned a promise the U.S. made in Paris nearly 10 years ago to combat climate change, and has instead promised to ramp up fossil fuel production and remove environmental protections. Sirota believes state lawmakers still have a role to play.
"We are trying to make sure that Colorado is able to protect its air and water and meet our climate goals, as we see this being unwound federally," Sirota explained.

Nitrous oxide (N2O) emissions from agriculture are not only coming from soil. They’re also flowing through the streams that run alongside farms, a recent study finds. Researchers at the University of Minnesota and University of Illinois discovered more than one-third of regional nitrous oxide emissions were measured from streams.
While often overshadowed by the more widely known greenhouse gases like carbon dioxide and methane, nitrous oxide is the third-largest contributor to greenhouse gas emissions. Nitrous oxide also has an EPA-rated “Global Warming Potential” 273 times that of carbon dioxide (over a 100-year timescale), and is a significant contributor to ozone depletion. This means that even small amounts of nitrous oxide emissions can have a disproportionately large impact on global warming. And the flip side is also true: taking some action, including better manure management and eating less meat, can have a big climate impact for the better.
The discovery highlights a previously overlooked pathway for nitrous oxide to enter the atmosphere: as agricultural soils undergo the process of nitrification and produce nitrous oxide, the gas is transported via runoff into nearby streams. During the nitrification process, bacteria in soils break down ammonia — in this case from fertilizers — into nitrates that can produce nitrous oxide gas. While this gas may be released immediately from the soil, it can also become trapped in the soil or dissolve in water, only to be carried into streams during rainfall or snowmelt.
“What we basically found is there [are] other pathways, and this stream emission could be important,” Zhongjie Yu, hydrologist and researcher in the study, tells Sentient.
Traditionally, when researchers consider nitrous oxide emissions from agriculture, they focus on soil. Excess nitrogen from fertilizers accumulates in agricultural soil, where it can be transformed into nitrous oxide, and released directly into the atmosphere. However, this new study suggests that emissions from streams — carrying runoff from agricultural fields — can be just as important, if not more so, in certain regions. Factory farms can be a major driver of this issue, as these operations produce large amounts of waste, composed partly of nitrogen.
When researchers consider initial nitrous oxide emissions, it’s often in the context of fertilizer input to soil. This excess nitrogen accumulates in agricultural soil, and can then lead to the direct release of nitrous oxide into the atmosphere.
Though the study used only the University of Minnesota’s Tall Tower Trace Gas Observator to sample air emissions, Yu and his research team are confident about the data.
“We found that N2O is emitted from streams, but we believe it’s originally from fertilizer nitrogen. It is just carried by water, and gets emitted from those aquatic systems. It’s not saying it’s a natural source, but it’s still related to fertilizer nitrogen. But it just provides another pathway that N2O gets lost from some land to the atmosphere.”
Yu also emphasized that agriculture is the dominant source of human-caused nitrous oxide emissions. This study not only challenges the conventional understanding of agricultural emissions, but also underscores a broader issue: agricultural runoff is not just a water quality problem — it is also a major contributor to climate change.
Nitrous Oxide: the Lesser Known Climate Threat
Human activities are significant contributors to nitrous oxide emissions. While other natural sources, such as the ocean, also release nitrous oxide, agricultural practices — particularly fertilizer application — are by far the largest contributor of anthropogenic emissions.
This gas is primarily produced when nitrogen-based fertilizers and manure are applied to agricultural soils. Microbes in the soil convert this nitrogen into nitrous oxide through processes such as nitrification and denitrification. The situation is made worse by the practices of industrial farming, which rely heavily on the use of synthetic fertilizers and animal waste.
Around 12 million tons of nitrogen are applied to crops each year in the United States. An EPA report found that agricultural soil management — like fertilizer use and other practices that boost nitrogen levels in the soil — accounts for nearly 75 percent of the United States’ nitrous oxide emissions. Within the agricultural sector itself, it makes up almost half of all emissions.
These soil management practices are primarily intended to optimize crop production, but much of the land is used for growing farm animal feed and biofuel crops. In 2020, only a small fraction of corn grown in the U.S. — less than two percent — was used for direct human food. Around 31 percent was dedicated to biofuels such as ethanol, while the majority, around 35 percent, went toward feeding livestock. With global meat consumption steadily rising, the demand for animal feed is expected to increase, further driving the need for feed crops like corn — along with higher fertilizer use and a corresponding rise in nitrous oxide emissions.
And now, the source of these emissions isn’t just the soil. Stream emissions can contribute to a much larger portion of annual nitrous oxide emissions than researchers previously thought.
“The high contribution of stream emissions suggests that soil emissions may have been overestimated in current regional nitrous oxide budgets,” Yu writes.
Yu points out that the link between agricultural runoff and stream emissions has often been overlooked in past research. Traditional methods use soil chambers to measure nitrous oxide emissions, a method that places a closed chamber over the soil, in order to capture any gases emitted from it. This approach primarily measures how much nitrous oxide is released directly from the soil, but misses the nitrogen that leaches out of the soil and flows into water systems, where it can then be converted into nitrous oxide and emitted to streams.
The Bottom Line
The source of nitrous oxide emissions from agriculture is more complex than scientists once thought. While traditional efforts to reduce nitrous oxide emissions have focused mainly on fertilizer management and improving soil efficiency, this new discovery emphasizes the importance of looking at the entire agricultural system, including runoff into streams. If the number of factory farms continue to rise, there is likely to be a rise in nitrous oxide pollution, particularly in streams, due to greater fertilizer use and runoff.
Yu mentions that improving water and nutrient management not only benefits water quality, but can also be a crucial tool in reducing greenhouse gas emissions. Fertilizer and manure runoff, especially from factory farms, can carry large quantities of nitrogen into waterways, which may then be converted into nitrous oxide — further complicating efforts to mitigate emissions from agriculture.
“We need to be a little bit careful here, because that water gets leached from surface soil and can end up in streams and rivers, carrying a lot of that greenhouse gas to those systems and having an impact there,” Yu says.
