Three Interesting Facts About Electricity

Electricity turns dark into light, makes hot foods cold and cold foods hot, washes the dishes and searches the internet. It is essential to our everyday lives, so much so that we rarely think about it. But behind the scenes, interesting things are happening.

Here are three interesting facts about electricity that cause even some experts to scratch and shake their heads.

1. Electricity must be used or stored after it’s generated.

A rechargeable battery stores electricity — more on that later. But the kind of electricity you use in your home needs to be used after it’s generated.

It’s true. Electricity produced from power plants, solar panels, wind turbines and hydro dams in the U.S. needs to be perfectly timed for when you decide to cook dinner, wash clothes or watch TV. The national grid, made up of power generators, wires and substations, is an incredibly complex network that makes electricity flow smoothly.

A vast and intricate system of devices controls that power flow in a precisely balanced way so that when you flip a switch calling for additional electricity, somewhere else a power source ramps up to provide the additional electricity you require.

It’s one reason utility operators must be strategic when adding renewable energy to the nation’s fuel mix — a coal or natural gas plant can ramp generation up or down fairly quickly to meet changing energy demand. Solar energy and wind power depend more on the whims of Mother Nature, which adds an extra challenge to power management. However, technology advances are making this challenge easier to deal with and more large-scale battery storage is also helping.

Big batteries offer another way for electric utilities to better balance the flow and timing of electricity and large-scale battery storage technology is improving rapidly. A few of Colorado’s electric cooperatives have incorporated battery storage into their distribution systems and more storage is being planned. Wider use of large utility-scale batteries will make it much easier to add more solar and wind energy to the grid, allowing electric co-ops and others to store energy that’s generated when it’s breezy and sunny for use at night and during calm weather.

2. Power out? Blame a squirrel.

While severe weather causes most outages, if it’s nice out and your electricity goes off, it could be caused by a squirrel.

We all know to play it safe around electricity, but squirrels don’t. They scamper and chew around transformers, substations and utility poles where they can disrupt high-voltage equipment, shutting down power for you and your neighbors.

We all know to play it safe around electricity, but squirrels don’t. They scamper and chew around transformers, substations and utility poles where they can disrupt high-voltage equipment, shutting down power for you and your neighbors.

But it’s not just squirrels. Snakes, birds and other critters can find their way into dangerous places. There’s no official record-keeping of wildlife-caused power outages, but estimates run as high as 20%.

Electric utilities are constantly devising new ways to keep wildlife away from dangerous electrical equipment—the resulting power disruptions are inconvenient for us energy consumers, and almost always fatal for the animal.

3. Highways could charge electric vehicles in the future.

If researchers have their way, electric vehicles wouldn’t need to plug in — they could charge while they’re being driven.

“Wireless dynamic charging” projects are underway around the world. The idea is similar to wireless chargers you can buy for your home electronics, the kind you can set near a charger rather than actually plugging in the smartphone or other device.

Charging cars while they’re driving along the freeway is of course a lot more ambitious. But some developers predict that within five years, in addition to today’s special high-occupancy-vehicle lanes for rush-hour traffic in large cities, there could be stretches of vehicle-charging lanes.

Futurists expect electric trucks as the most likely users of wireless charging lanes. Most electric cars, after all, can charge overnight in a residential garage. Wireless dynamic truck charging could keep the deliveries rolling rather than having drivers sitting and drinking coffee for the several hours it could take a conventional plug-in to get trucks back to full power.

Electricity is such a basic part of our everyday life, so it’s easy to forget about it. But every now and then it’s good to think about all its benefits and mysteries. That awareness can help make sure we pay attention to safety precautions, but sometimes it’s good just to be amazed.

Cooperative Program Enhances Local Small Businesses

In an innovative approach to enhancing its rural small business community and economy, Pueblo West-based San Isabel Electric offers a unique program.

The electric co-op distributes pass-through loans with 0% financing for qualifying projects to local businesses, nonprofits and public entities. This is through the U.S. Department of Agriculture’s Rural Economic Development Loan and Grant program.

Here’s how it works: The USDA provides the loan to San Isabel Electric, which then passes the loan through to local businesses in its service territory. The local business or nonprofit is responsible to repay the loan to SIEA, and the cooperative is then responsible for repayment to the USDA. San Isabel Electric may lend up to $1.5 million in total loans, and up to $300,000 in revolving loans.

The most recent recipient of a pass-through loan from SIEA is My One Hour Office, a coworking space in Walsenburg. Owner Mary Jo Tesitor said in a recent press release, “With a manageable low-or-no interest loan of less than $20,000, a small rural business can complete upgrades and improvements that may have been sitting on the back burner for a while.”

Tesitor believes the revolving loan program for small businesses can make a real difference for rural Colorado. And “is a great use of USDA funds. Small business owners will pay back into the fund, recirculating that money and growing the economy,” Tesitor said. She plans to use the REDL&G program funds to purchase virtual video conferencing equipment, a Wi-Fi management system and office furniture.

A previous REDL&G loan was issued to the La Veta Fire Protection District to support construction of its new fire station. San Isabel Electric is continually working with local rural businesses, nonprofits and public entities to process REDL&G applications. The co-op is also actively seeking a nonprofit or public body partner in the service territory to establish a revolving loan fund. An RLF would allow San Isabel Electric to issue these types of loans more quickly, without having to wait for USDA approval.

“To set up a revolving loan fund, we must issue a large loan to a nonprofit or public body entity, like a hospital, or local government organization. As they pay it back to us, we bank it, and then re-lend it. We can keep it going as long as we wish, as long as we’re following the USDA’s rules,” Laura Getts, San Isabel Electric’s business development manager said.

This is just one example of how a Colorado electric cooperative enhances community resilience through innovative programs.

Electric School Buses Get a Push

The move to electrify school buses across the country got a new push when The Beneficial Electrification League announced an initiative to accelerate the deployment of these buses in electric cooperative service territories.

BEL launched this coalition effort in advance of federal funds targeted to electric school buses in the Investment in Infrastructure and Jobs act passed by Congress in 2021.

“Colorado’s rural electric cooperatives are excited to partner with schools to bring the benefits of electric school buses to communities all across the state,” said Kent Singer, CREA executive director. “We believe these buses can bring a lot of benefits to students, the school systems and the electric cooperative community.”

In Colorado, Tri-State Generation and Transmission Association, CREA and three local electric co-ops are participating in the BEL initiative. Colorado also has two electric school buses deployed with the assistance of local electric co-ops with a third soon to be added.

Driving EVs in Winter Weather

The woes (and whoas!) of driving electric in cold temperatures
By Amy Higgins

Weather conditions in Colorado are diverse and, depending on where you hang your hat at the end of the day, you could be dealing with intermittent ice and snow when getting around town or perhaps hazardous conditions are often part of your everyday life all winter.

Whether gas-powered, electric or a combination of the two, cold weather affects your vehicle’s performance, according to fueleconomy.gov. This official U.S. government source for fuel economy information reports that the fuel economy for gas-powered vehicles can drop as much as 24% in cold temperatures; up to 34% for hybrids; and 39% for electric vehicles.

A GCEA consumer-member drives to the slopes with the co-op’s Chevy Bolt.

Gunnison County Electric Association, with offices in Gunnison and Crested Butte, is in an area of Colorado where temperatures can reach below negative 20 degrees. The electric co-op has a Chevy Bolt and a Tesla Model 3 in its fleet of EVs and tested the vehicles at subzero temperatures.

“We noticed that when you have subzero temperatures, the battery loses up to 37% efficiency compared to the warmer temperatures,” says GCEA Member Relations Supervisor Alliy Sahagun.

These tests, Sahagun says, have helped educate GCEA consumer-members about what they can expect with an EV. For example, road trips could be arduous if EV owners are not mindful of this expected decrease in productivity, the weather conditions and their vehicle’s current charge status.

On the flip side, EVs perform well, if not very well on shorter trips. This is the third winter Chris Michalowski’s family has owned its Chevy Bolt — his wife’s preferred vehicle when driving around town during the week. A single charge provides more than 200 miles of range, so on short trips, she doesn’t have to charge again until later that evening during their electric co-op’s off-peak hours. Now outfitted with snow tires and ski racks, the Bolt is their go-to when heading to the ski resort. “It’s small so it can sneak into tight parking spaces at the ski resort, and you don’t have to wait for it to warm up,” says the Granby-based Mountain Parks Electric power use advisor. “I have a pickup truck as well, but I’d much rather take our EV to the ski resort.”

Sahagun says she frequently gets questions about how GCEA’s Bolt and Tesla handle in the snow and on ice. She says they perform “really well.” Because of the battery’s weight, EVs have a low center of gravity which helps the vehicle hug the road, preventing it from sliding. However, this low center of gravity doesn’t provide a lot of clearance, which can be precarious around higher snowdrifts and unplowed roads.

“If the roads are plowed, I’ve not had any problems with them — they do great,” Sahagun says. A GCEA member shared with her an experience when his truck became stuck in the snow: “He hitched his pickup truck to his Tesla Model S and he pulled it out of the snow, so they’re pretty strong, pretty powerful.

One clear advantage of an EV when compared to a gas-powered vehicle is its ability to provide heat almost instantaneously. “I tell people it’s like a hair dryer. Boom. The warm air starts coming out,” Michalowski explains. “For those short trips to the grocery store in the winter, by the time you get there and back, the car is finally starting to warm up [in a gas-powered vehicle]. It’s not the case with electric vehicles because the heating system is electric. It’s pretty much warm air right from the get-go.”

Although there is a decrease in range during winter temperatures, EVs are highly efficient when navigating around town or driving to and from work. And the amount of “fuel” remaining in your EV isn’t as important at the end of the day as with a gas-powered vehicle. “If you go home with 40 miles of range left or 100 miles of range, it’s all the same,” Michalowski explains. “It’s kind of like your cellphone — you don’t really care what the battery life is like as long as it works and you’re able to plug it in and it charges again.”

Analyze before you finalize
The catchphrase “range anxiety” — the fear of being stranded without a charge when needed — still has some potential EV buyers reeling, but this concern is swiftly dwindling. President Joseph Biden’s American Jobs Plan proposes a national network of 500,000 charging stations by 2030, up from the Department of Energy’s current count of around 50,000.

EVs come with a 120-volt, Level 1 charger, which can be plugged into any outlet, but they can take 16 hours or more to fully charge. Upgrade to a Level 2 charger, set it to charge when you go to bed (yes, you can program your charger), and wake up to a full charge the next day. And fast chargers — 34 Colorado locations and growing — can boost your battery 80% in 30 minutes.

“When I bought my Bolt, there wasn’t a single fast charger in the county and here we are two years later and now there are four fast chargers in all four corners of the county,” Michalowski says. “It seems all the time new public chargers are getting installed. It just gets better and better as far as what’s available.”

Watch for Ride and Drive events hosted by your local electric co-op, like this one sponsored by MPE.

Educate yourself about EVs and take a test drive or keep an eye out for EV Ride and Drive events in your area. “From our own experience, just getting people behind the wheel is a huge game changer,” Michalowski says about MPE’s Ride and Drive events.

Consider your budget, your lifestyle and your daily commute to and from work, the grocery store or anywhere else you visit routinely. Not thrilled about the selection? The soon-to-be-released electric Ford F-150 as well as new all-wheel-drive options may sway you to make the switch. In the end, whether or not to drive an EV is a matter of preference.

New EV Chargers Hit Winter Park Resort

Winter Park Resort is sporting 14 new EV chargers, thanks to Granby-based Mountain Parks Electric and its power supplier, Tri-State Generation and Transmission.

According to a January press release, Tri-State provided project funding to support and expand EV use in the region and MPE facilitated project planning and coordination. At the resort, Village Parking Garage now has six chargers and the outdoor B Lot has eight. Representatives from the co-op and Tri-State presented Winter Park Resort with a check at a January 11 ribbon cutting event.

MPE General Manager Mark Johnston said, “Since the ski resort chargers were energized a couple of weeks ago, skiers have been plugging in.” And the co-op expects usage to increase over time as consumers get more access to EVs and as charging infrastructure continues to grow and develop in mountain communities.

Co-op Rebates Give Back Cash and Smiles

Colorado’s electric co-ops with Tri-State Generation and Transmission have offered energy-efficiency rebates in partnership with their power supplier for years. Rebates have been made available for LED bulbs, Energy Star appliances, electric water heaters and much more. It’s an innovative and well-received program that’s helped thousands of consumer-members. Rebate programs not only give cash back to consumer-members, but they can also increase efficiency efforts at consumer homes, which typically translates into savings on residential electric bills. Who doesn’t like that?

The concept of consumer product rebates is nothing new and noteworthy. But the rebate landscape is evolving and expanding to keep up with new technologies. Many co-op rebate programs now often include smart thermostats, home EV chargers, electric lawn mowers, and other less traditional items that benefit consumer-members and are — dare we say — really fun!

In addition to providing extensive rebate information via websites and other marketing materials, co-ops often get the word out about rebate opportunities and offerings by hosting giveaways for popular and exciting rebate-qualifying items.

Fort Collins-based electric cooperative Poudre Valley REA offers rebates for electric bicycles. In December, the co-op reported that a recent electric bicycle giveaway recipient was having the time of his life on the new e-bike he won in a drawing the co-op hosted.

Earlier this month, Mountain Parks Electric gave away an electric snowblower to one lucky consumer-member a who attended a community event hosted by the Granby-based electric co-op.

Mountain View Electric Association’s popular GO ELECTRIC! Outdoor Power Equipment Giveaway helps consumer-members make the switch to electric and promotes the Limon-based co-op’s rebate program. In its contests, the co-op gives away items that assist in taking care of outdoor residential spaces: Electric lawnmowers, trimmers, power washers, chainsaws and more.

The benefits to transitioning to electric products are endless — especially when replacing gasoline-powered equipment. Consumers who use electric equipment experience zero emissions when mowing their lawn, power washing their back deck or removing snow off their driveway after a big storm. The noise factor of many of these activities nearly goes away. While no one could ever really call any chainsaw “quiet,” electric options operate at 10-20 decibels quieter than the gas equivalent. Electric lawnmowers, however, are whisper quiet and offer a huge sigh of relief for the neighbors of the weekend warrior who loves to mow her lawn at 8 a.m. on Saturdays.

Electric Co-op Helps Ouray Go “Totally Green”

The City of Ouray is the most recent participant in San Miguel Power Association’s Totally Green program. CREA’s Energy Innovations newsletter reported on this program in January 2020, and Ouray joins other local businesses and government entities that consume 100% renewably-resourced electricity.

The Ridgway-based electric co-op typically fulfills its Totally Green program requirements with renewable energy from the open market. In this case, 100% of the city’s municipal electricity use is covered by the output of the Ouray Hydroelectric Plant.

SMPA members may voluntarily sign up for Totally Green and are charged an extra 1 cent per kilowatt-hour. The net proceeds from the City of Ouray’s contribution goes to the SMPA Green Fund that is used to develop locally-sourced, renewable energy projects. The Green Fund is also used to help the co-op give rebates to its consumer-members for energy efficiency and beneficial electrification upgrades and improvements.

Co-ops Add Microgrids to Improve Resiliency

By Sarah Smith

Access to reliable electricity is top-of-mind for CREA and its member electric cooperatives. But natural disasters such as wildfires and winter storms can affect that reliability by taking down electric infrastructure and isolating rural areas (sometimes for long periods of time).

Two projects exemplify how Colorado’s co-ops are implementing microgrids, which are autonomous energy systems that serve specific areas and provide backup electricity with common-sense solutions when needed in emergencies. Poudre Valley Rural Electric Association in Fort Collins went live with a microgrid in Red Feather Lakes in October. Holy Cross Energy in Glenwood Springs is moving forward with another microgrid project on the Western Slope.

Poudre Valley REA wors with Red Feather Lakes representatives to install battery storage for its microgrid.

Red Feather Lakes is 60 miles away from PVREA’s headquarters. Historically, it has been prone to disasters that have major impacts on its single transmission line bringing electricity to the town. High elevation, heavy snowfall, dangerous winter driving conditions, fallen trees, wildfires and even tornadoes put this mountain town at risk for losing power.

PVREA leaders decided to create a microgrid after the local library won a grant to install solar panels and a battery to improve resiliency and cut electricity costs. The microgrid was installed at the local fire station, which has diesel generators and is located across the street from the library. PVREA controls the microgrid and owns the 140-kilowatt/448-kilowatt-hour battery. Now in place, the microgrid will provide secondary power for several hours if a disaster occurs.

“This project is rooted in community, which is a huge part of who we are as a cooperative. The Red Feather Lakes community came together to solve a need and approached us with the project. As we learn more about this microgrid, we can share that information with other cooperatives across the nation so that we all may better serve our members,” said Sam Taggart, strategic communications director for PVREA.

The small community in northern Colorado gets its electricity delivered by a single transmission line and will benefit from its new microgrid if that line goes down.

The project also would not be possible without the assistance of PVREA’s partners. The National Rural Electric Cooperative Association led the initiative in Red Feather Lakes, which is one of four microgrid projects involving five co-ops nationwide. NRECA connected the co-ops with a U.S. Department of Energy project, which provided $1.3 million in energy storage grants. Pacific Northwest National Laboratory and Sandia National Laboratories are also partners in the project. In addition, PVREA’s board of directors provided matching funding for its microgrid.

“The partners we had on this project were extremely important to us. We could not have completed this microgrid without our local, regional and national partners,” Taggart said.

HCE is also making headway with the creation of a microgrid system. The electric co-op is working on a feasibility study with Pitkin County and the Roaring Fork Transportation Authority to determine the practicality of a microgrid connecting a cluster of public facilities near the airport. The microgrid would be powered by renewable energy, independent from the larger electric grid. These facilities, which include the Aspen-Pitkin County Airport, the county’s public works facility, and RFTA’s bus barn, also would be protected from outages if service to the rest of the area is temporarily compromised by an outage. The feasibility study is funded by a $200,000 grant from the Colorado Department of Local Affairs.

With most of the research completed, HCE is looking ahead and fully anticipating making the microgrid a reality.

The urgency to create a microgrid in HCE territory emerged after the Lake Christine Fire in July 2018, which scorched more than 12,500 acres. The wildfire shut down power to the Upper Roaring Fork Valley, which includes the towns of Aspen, Snowmass Village and Basalt, with a year-round population of around 18,000. Three out of the four transmission lines running into Aspen were disabled and if the fourth line had gone down, it could have led to days or even weeks without electric service. This is not a possibility HCE is willing to face again for its members.

With the research phase of the microgrid project nearly complete, HCE is busy planning the next steps and the next phase of the project. Several grant opportunities are in the approval process, including one from the Colorado Department of Local Affairs. HCE will also cost-share part of the project, with funding going toward staffing needs and a protection plan to ensure the main grid is still being protected.

“Microgrids are really good on ‘black sky days’ and serve as a secondary source of power during a crisis. But there is also a great benefit to the grid on ‘blue sky days,’ and there is value in adding these batteries,” said Chris Bilby, research engineer for HCE.

“By installing a microgrid, we are actually going back to the old days. Many mines and train stations used to operate on microgrids, but because of the pollution, these transmission factories were moved farther away from populated areas, so people didn’t have to breathe that bad air in. With a clear path to clean energy in the near future, we can now move these microgrids back to communities,” Bilby continued.

In the face of a crisis, and especially when it threatens the resilience of the electric system, CREA and its electric cooperatives are working with their communities and other partners to find solutions. PVREA and HCE are examples of what it means to lead and overcome challenges to make reliable electricity readily available, despite any circumstance. Microgrids were the way of the past and now are an important step toward the future.

Y-W Electric Installs New EV Charger

Earlier this month, Y-W Electric Association installed a ChargePoint EV charger in Akron. A ribbon-cutting ceremony was held November 12 to celebrate this innovative step that supports EV infrastructure development on the eastern plains. The co-op’s goal is to “encourage more folks to obtain EVs, to contribute to the charging infrastructure to reduce range anxiety,” according to Y-W Member Service Manager Andy Molt.

The charger installation was made possible with funds from a Charge Ahead Colorado program grant through the Colorado Energy Office and funds from Tri-State Generation and Transmission, the electric co-op’s power supplier.

Hybrid Bucket Truck Joins United Power’s Fleet

A first-of-its-kind bucket truck joined United Power’s fleet.

The innovative, hybrid model bucket truck uses battery power to raise and lower the bucket as well as the bucket jib. It was debuted in September by the Brighton-based electric cooperative at the 2021 Utility Expo in Louisville, Kentucky.

The electric boom and jib (a small crane attached to the bucket, allowing line crews to lift heavy materials up to bucket height) provide a cleaner, quieter idle time. Not only does this save diesel fuel and reduce emissions, it will improve safety conditions for line crews, according to United Power Fleet Manager Bill Hottell. He said in a recent press release that it’s a safer option than a traditional truck because the bucket crew will have an easier time communicating with the ground crew without having to compete with the noise of an idling diesel engine.

The hybrid truck is assigned to the Carbon Valley Service Center to respond to outages on the west side of United Power’s service territory. People in the community can identify this new truck as the hybrid model because it was branded with green lightning graphics on the side.
