People within the San Juan Mountain neighborhood of Silverton, who know a factor or two about snow, known as a day final February “Snowpocalypse” and it was dangerous. Very dangerous.
Whole white out, snow blowing sideways, two mountain passes on U.S. 550 closed, reducing off the high-elevation city. San Juan County Sheriff Bruce Conrad issued a stay-in-place order to residents after which the lights went out.
The facility went down at 8:30 a.m. on Feb. 22 and took with it the fuel pumps on the service station and the digital money register on the grocery. City Corridor was shut. At Silverton Medical Rescue, it was a wrestle to open the heavy storage doorways, which relied on electrical motors.
Houses with fuel furnaces went chilly, although many on the town have wooden stoves and a few nonetheless warmth with coal. Water or sewer service went down.
Sheriff Conrad managed to arrange a conveyable generator exterior the grocery retailer and run an extension wire to the register.
“This manner anyone who wanted meals, water might get it,” mentioned DeAnne Gallegos, a spokeswoman for the San Juan County Workplace of Emergency Administration. “A part of it’s psychology, you need to know there are some assets when the passes are closed and we’re snowed in.”
It took nearly eight hours for the city’s electrical cooperative, the San Miguel Energy Affiliation, to get the lights again on.
Whereas Snowpocalypse was excessive, it was simply one in all a string of blizzards, avalanches and energy outages final winter suffered by this one-time mining city — elevation 9,318 ft, inhabitants 650 give or take.
Two weeks earlier the substation on the town went down throughout one other snowstorm. The ability is operated by the Tri-State Technology and Transmission Affiliation however the affiliation couldn’t get a crew over Molas Move from Durango.
Prematurely of the blizzard, San Miguel Energy despatched an additional lineman to Silverton — reinforcements for the city’s one resident lineman — and with some teaching from Tri-State, the 2 fastened the issue.
About two weeks after the Snowpocalypse there was one other storm and one other outage, however the lineman and the city’s one ambulance had been each in Durango and wanted a state snowplow to convoy them again to city.
In all, Silverton weathered half a dozen blizzards in a row and 6 outages. “It was a significant wake-up name,” Gallegos mentioned. “We knew we needed to do one thing.”

Small-scale photo voltaic system for gentle within the storm
That one thing is to create a complete resiliency plan for the city. The centerpiece is a microgrid — a mix of photo voltaic panels and a big battery — to supply backup energy for your complete neighborhood.
San Miguel Energy Affiliation, or SMPA, is selling using microgrids in Silverton and three different mountain cities (Ophir, Rico and Ridgway) as a means to deal with the outages that chronically plague these distant communities. Since June of 2020, Rico — elevation 8,825 ft, inhabitants 350 or so — has had 21 outages.
The goal is to place a microgrid in every city, creating an area supply of electrical energy to feed the native wires with not less than six to eight hours of energy, extra if the photo voltaic panels can replenish the battery.
“The community-scale microgrids we’re engaged on are actually unprecedented,” mentioned Terry Schuyler, the SMPA account govt overseeing this system. “We are able to do this as a result of our communities are considerably small.”
“It might change into a nationwide mannequin,” Schuyler mentioned, “an answer that might be replicated in different communities.”
Smaller-scale microgrids are additionally being put in within the area to protect in opposition to blackouts. The San Miguel Sheriff’s Workplace already has its personal microgrids at its headquarters and jail, with photo voltaic panels and batteries. Telluride Excessive College plans to put in one, and SMPA is placing one in at its headquarters.
The rising curiosity amongst rural communities in using microgrids as energy backups is being buoyed by important federal and state {dollars} to finance them.

In July, the U.S. Division of Vitality introduced a $14.7 billion funding alternative to deliver microgrids to underserved and Indigenous communities and a few of that cash is already making its option to Colorado.
5 communities — Parachute, Basalt, Granby, the Ute Mountain Ute Reservation and Silverton — every gained a $100,000 Energizing Rural Communities prize from DOE to advertise microgrids and clear power initiatives. Silverton is utilizing it to fund its resiliency program and microgrid planning.
The Colorado Division of Native Affairs and the Colorado Vitality Workplace acquired $17 million from the federal 2021 Bipartisan Infrastructure Invoice funding for grid resilience.
The state power workplace is utilizing $7 million to develop a rural microgrid roadmap for the state, in addition to packages to fortify rural grids. “The query we are attempting to reply is what are the insurance policies and financing that must be up to date to advertise deployment of microgrids,” mentioned John Parks, a Colorado Vitality Workplace coverage guide.
It might change into a nationwide mannequin, an answer that might be replicated in different communities.

DOLA is utilizing the opposite $10 million for grants in its Microgrids for Neighborhood Resiliency Program, which was created in 2022 by state laws with $3.5 million appropriation.
Eight grants for microgrid planning have been awarded — Ophir, Ridgway and Rico every obtained about $30,000. Additional down the highway there shall be as much as $1 million for every building challenge. Different grants went to initiatives in Larimer, Delta, Pueblo, Huerfano and Jefferson counties.
“We’re seeing a number of demand,” mentioned Julia Masters, the DOLA microgrid program supervisor. “They’re pondering of microgrids as a path to resiliency, power independence and self-reliance.”
The federal regulation on photo voltaic tax credit was additionally broadened to allow a nonprofit, like SMPA, which doesn’t pay taxes, to get credit as direct funds.
“What actually stimulated our curiosity in microgrids was the unprecedented availability of grant funding, with out which we wouldn’t have the capital to go after these initiatives,” Schuyler mentioned.

The important thing, Schuyler mentioned, is that the price of the initiatives and the electrical energy they produce have to be decrease than the value of the wholesale electrical energy the cooperative purchases from Tri-State. If not, the remainder of SMPA’s clients can be subsidizing the 4 mountain cities.
The microgrid may be key to fixing a basic grid downside for the co-op. Utilities look to supply redundancy with a “looped feed,” so if there’s a downed line, say, on the east facet they will ship electrical energy round on the west.
However Silverton, Rico and Ophir have solely single traces into city. Electrical energy useless ends. If the road goes down, the city is out of luck.
Ridgway’s story is completely different. It’s on a circuit, although it relies upon upon a line precariously snaking over Crimson Mountain Move, elements of which had been put in within the Nineteen Twenties.
The biggest of the cities, with a inhabitants of 1,200, Ridgway wants backup since it’s residence to a medical clinic, the Ridgway Fireplace Division, Ouray County Emergency Providers providers and the Colorado Division of Transportation highway store for Ouray County.
Backup technology plan stopped chilly in Ophir
Regardless of the flood of state and federal {dollars} and enthusiasm for microgrids, the experiences of the mountain communities present that to a lesser or larger diploma, putting in the techniques could also be difficult. Think about Ophir’s story.
Ophir, one other outdated mining city in a valley 13 miles from Telluride, is hemmed in by two thirteeners: Lookout Peak and Yellow Mountain. The city sits at nearly 9,700 ft, with the ability line working over the cross of one other thirteener, Lizard Head.
“Coming into Ophir you cross six completely different avalanche paths,” mentioned Jon Wontrobski, the city supervisor. “So, people in Ophir are used to being reduce off and to outages. The longest was three days.”
The city’s web site places the inhabitants at “180 people, 51 canines.”
“The canines are positively a part of the make-up of the city. them nearly in addition to your neighbors,” mentioned Andy Ward, Ophir’s mayor.
In 1875, gold was found within the valley and by 1885 there have been 200 individuals within the mining camp, whose title comes from a city talked about within the Previous Testomony. In Hebrew, Ophir is translated variously as gold, riches, wealth.
However the mines closed in 1910, and by 1970 there was just one recorded family residing in Ophir. Then got here a resurgence. “Within the late ’70s and early ’80s, it was principally stuffed with, you realize, guys and canines,” mentioned Ward, who got here to city within the early ’90s.
Households began shifting in and the variety of kids, 40, is now approaching the variety of canines. Most folk commute to jobs in Telluride, although Ward mentioned Ophir is “much less a bed room neighborhood and extra of a Telluride refugee camp.”
The avalanches additionally reduce off the city’s kids from college down in Telluride, however when it’s secure the youngsters, led by adults, have walked over the avalanche path to rendezvous with a faculty bus.
Given all this one would assume Ophir would welcome the $30,000 state grant and the thought of a microgrid on the town. However one must assume once more.
Ophir is one in all solely two municipalities in Colorado with a basic meeting type of authorities, casually known as a GA. The opposite is the Boulder County neighborhood of Ward. There isn’t any city council, planning or zoning boards. Whoever reveals up on the month-to-month assembly — and is a registered voter with an Ophir handle and has lived within the city for 22 days — will get to vote on city enterprise.
The spirit of Ophir is defending Ophir and its setting.

And so, when there was a movement to present SMPA the go-ahead to do a microgrid feasibility examine, it provoked an extended debate and a few appreciable pushback throughout November’s basic meeting.
“The spirit of Ophir is defending Ophir and its setting,” one speaker, on a recording of the assembly, opined. Among the many concepts floated on the assembly had been whether or not the city ought to attain out to Tesla or think about inexperienced hydrogen.
There have been 28 votes to maneuver ahead, 26 votes in opposition to and two abstentions. Abstentions rely as no votes beneath Ophir guidelines and the tie vote defeated the movement.
Then there was a lot dialogue of whether or not the 2 abstainers understood they had been actually casting no votes. “One of many perils of GA authorities is that folks make votes with out realizing what they’re voting for or in opposition to,” Wontrobski mentioned.
EcoAction Companions, a nonprofit funded by Telluride and San Miguel County to advertise sustainability packages, is the lead company for neighborhood outreach for the microgrid initiatives.
However retaining Ophir on observe and away from inexperienced hydrogen or energy partitions has been a problem, mentioned Kim Wheels, the group’s power specialist and an Ophir resident. “It has been onerous to maintain the dialogue targeted on what the planning would deliver. Lots of people are specializing in what their private viewpoint is.”
Ward mentioned, “We rolled out the challenge, not in a really efficient means and so, boy, that basically crippled us at first.”
The vote was significantly perplexing, Wheels mentioned, since in 2018 Ophir handed a decision to attain 100% greenhouse-gas-free electrical energy.
“It wasn’t our intent to create divisiveness,” SMPA’s Schuyler mentioned. The co-op and city officers are actually searching for another method, resembling a standalone battery or extra emphasis on rooftop photo voltaic.
Till then Ophir is on the danger of extra blackouts. “When it does go down, lots of people truly get pleasure from that point,” Ward mentioned. “, you go to candles or lanterns or no matter you employ, and it’s one thing that folks truly stay up for not less than for brief durations.”
People on the town additionally see avalanches as a type of leisure. “It’s nearly like a celebration,” Ward mentioned. “You get to look at, you realize, because the avalanche comes down and crosses the highway. It’s fairly thrilling.” YouTube is replete with Ophir avalanche movies.

Thoughts your western publicity
The issue SMPA has run into in Rico, which is 37 miles south of Telluride, hasn’t been native opposition however geography.
“The valley runs north to south, so all of the east-west websites are on slopes,” mentioned Chauncey McCarthy, the city supervisor. A pleasant flat acre or two with good western publicity is what a photo voltaic array wants.
SMPA has combed the Dolores County valley for a suitable location. “We’re working out of websites,” Schuyler advised the Rico Board of Trustees in December.
The Rico challenge can also should be rethought. “We’re studying as we go,” Schuyler mentioned.
Rico has a fuel station and a café, however no grocery retailer, so when the ability is out, or the city will get reduce off, there aren’t many assets.
“What’s actually difficult for us as properly is that we’ve one cell tower in our city fireplace station, and it has a battery backup,” McCarthy mentioned. “The battery backup in all probability … has wherever from one to 2 hours of communication. However as soon as the battery backup goes out on the cell tower, we lose all connectivity by way of any telephone calls and we additionally lose all emergency response capabilities.”

A tree got here down throughout a snowstorm Jan. 18, 2023, knocking out energy in Rico (the identical storm led to an outage in Ophir from, you guessed it, an avalanche). It took SMPA 4 hours to get the ability again on.
Whereas the Ophir and Rico plans are going through hurdles, and the Ridgway plan is in its earliest levels, Silverton is out in entrance in planning and funding after getting the DOE prize, in collaboration with SMPA, EcoAction and the county.
“We are attempting to determine how you can be extra sustainable and resilient,” Silverton city administrator Gloria Kaasch-Buerger mentioned.
“The outages primarily occur within the winter, which is a really scary time, and it’s often throughout a blizzard or actually low temperatures with excessive winds, which places our weak inhabitants in danger,” she mentioned.
Backup turbines have been sprouting up round city. The hearth division has one. The varsity has one. The senior heart is about to get one. A generator for the water therapy plant has been on order for a yr. Some householders have them.
We are attempting to determine how you can be extra sustainable and resilient.
— Gloria Kaasch-Buerger, Silverton city administrator
Including to the crucial is the truth that Silverton is seeing speedy development as a tourism and recreation vacation spot — with the summer season inhabitants swelling to as many as 1,000 individuals — and the year-round inhabitants slowly rising.
“Our faculty is a superb form of litmus take a look at on our inhabitants,” Kaasch-Buerger mentioned. “In 2021, I do know it was someplace round 80 and now we’re as much as 90 youngsters.”
Silverton calls its resilience challenge GOLD — Purpose of Much less Dependency — and it has 4 goals: put together a resiliency plan for disasters, construct a microgrid, discover methods to maneuver the outdated, inefficient infrastructure to electrical energy and be part of a regional local weather motion plan to transition to sustainable power.
Jim Donovan, the San Juan County emergency supervisor, who describes his job as coping when issues get to “the worst of the worst,” is overseeing the resiliency plan. Silverton is the county seat and solely integrated city in San Juan County.
The resiliency plan, Donovan mentioned, “is constructing a framework to replace our electrical grid, usher in renewable power that can have battery backup” and on the similar time growing plans for residents so “they will get by any tough patch we’ve.”
It’s early within the starting stage, so city help is excessive, and everybody has their very own worst blackout story. Not lengthy after taking on as city administrator Kaasch-Buerger oversaw a particular election in October 2021.
“It had snowed a foot, temperatures reached zero and we had been with out energy for 12 hours,” she mentioned. “So, it was a horrible Election Day.”
