Colorado’s electric cooperatives advance innovative solutions that help reduce carbon emissions, such as providing consumer rebates for electric vehicles. Colorado’s electric cooperatives utilize technology to adapt to their consumers’ changing energy needs.

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.

Fueling for the Future

Researchers find potential in two low-carbon options
By Maria Kenevsky and Mona Neeley

When it’s time to fuel up your vehicle, you’re likely heading to the gas station or an electric vehicle charging station like most drivers in the U.S. But those might not be the only options in the future.

Research continues into alternative vehicle fuels, including hydrogen and biodiesel. This shift away from gasoline-powered vehicles comes with several benefits, including improving the country’s energy security and lowering vehicle emissions.

Hydrogen as fuel
One of the alternative ways to power a vehicle is with hydrogen in the form of a fuel cell. This form of fuel is potentially emissions-free and can be produced using domestic resources, according to a panel discussion at CREA’s October Energy Innovation Summit.

Just as with all-electric vehicles, fuel cell vehicles use electricity to power an electric motor. However, they use a fuel cell powered by hydrogen to create an electrochemical process to produce electricity. The hydrogen goes through an electrochemical process to produce the electricity, which then powers your car.

The only byproducts of this process are water and heat, emitted in the form of water vapor and warm air. Since the byproducts are clean, vehicles powered by hydrogen fuel cells produce no tailpipe emissions and are classified as zero-emissions vehicles.

Extracting the hydrogen itself can be a carbon-free process, depending on the way it’s done. One way is to perform electrolysis is using water to extract hydrogen, which requires power from another energy source. Using renewable energy, such as solar or wind energy, to power electrolysis provides a carbon-free process to extract the hydrogen. (There are other hydrogen sources that are less sustainable, such as producing it from natural gas, which emits carbon dioxide as a byproduct.)

Advantages of hydrogen-powered vehicles include fast fueling, long cold-weather range and high cargo capacity. With hydrogen, drivers can refuel a vehicle in under five minutes and gain more than 300 miles of driving range.

However, there are currently only a limited number of hydrogen refueling stations in the U.S., and most of these stations are in California. Colorado’s lone public hydrogen fuel station was installed at Colorado State University in Fort Collins in 2020. It is maintained by the CSU Energy Institute at the Powerhouse Energy Campus on North College Avenue.

It generates hydrogen on-site and is used to train students in hydrogen technology and by researchers gathering cost and operational data as they work toward future hydrogen station deployment for commercial operators in Colorado.

Biofuel/Biodiesel
Another form of alternative vehicle fuel is biofuel. Renewable biofuels are produced from biomass, which can be used in conventional gasoline- or diesel-powered vehicles. These fuels work in the same way gasoline or diesel does by fueling compression-ignition engines. Almost all diesel vehicles are capable of running on biodiesel blends, although vehicle owners should check their OEM engine warranty to ensure that higher-level blends of this alternative fuel are approved by the manufacturer.

One of the most common biofuels is ethanol, which is produced from sugars in corn or other grains, like sugar cane, sugar beets or rice. Sometimes biofuels can be blended with gasoline or diesel, or they can simply be used in pure form. Almost all gasoline sold in the United States includes 10% ethanol blended into the fuel, mostly from distilled corn. Scientists are currently working to find new ways to expand ethanol production by experimenting with different plants.

Biodiesel, a different form of biofuel, can be produced from vegetable oil, animal fats or recycled cooking grease, and can be used to power older cars that run on diesel. Since biodiesel is nontoxic and biodegradable, it is much safer than petroleum diesel if it’s released into the environment.

The most common sources for biodiesel production in the U.S. are soybean oil, corn oil and recycled feedstocks. There are several other nonmainstream biodiesel sources that can be manufactured from algae, municipal waste and wood chips. However, these options are much less common. The most common biodiesel blend is B20, which ranges from 6% to 20% biodiesel blended with petroleum diesel.

These alternative vehicle fuel options may not be mainstream yet, but as they come on line they can help lower our reliance on gasoline and diesel. As a bonus, these clean-burning options help to improve air quality and lower greenhouse gas emissions from the transportation sector.

There is great potential to see these alternative fuels expand over the years, and additional research efforts may help these fuels reach more individual consumers nationwide.

United Power Energizes School Generator

United Power recently installed a 625-kW diesel generator in its mountain service territory on the Gilpin County School District campus. This was done in partnership with the Gilpin County Office of Emergency Management.

The generator was installed by the Brighton-based electric cooperative to enhance safety for both the school and community members. Since the school district didn’t have a backup power option, Gilpin County was required to notify parents and send students home in the event of a power outage.

Not only will the generator help alleviate concerns for school administration and parents of students, Gilpin County Emergency Management can also activate the site as an emergency warming center during an extended outage in the area.

The generator runs on an ultra-clean, low sulfur Tier 4 diesel that incorporates advanced emission reduction technologies.

In addition to placing the generator, United Power also upgraded existing infrastructure to ensure the generator works well to power the entire school campus: school buildings, gym facilities, water storage and deliver systems, gym facilities and a day care center.

Innovative Microgrid Unveiled in Northern Colorado

Regular readers of this newsletter may remember the September 2020 edition that reported Fort Collins-based electric cooperative Poudre Valley Rural Electric Association was beginning work with community partners in Red Feather Lakes to build a microgrid.

Well, the new microgrid was officially unveiled earlier this month on October 7.

It consists of three main parts: a 140-kilowatt/446-kilowatt-hour Tesla Powerpack battery, a solar photovoltaic array and a 130-KW propane generator. Working together, these three assets meet the definition of a microgrid, as defined by the Department of Energy:  A group of interconnected loads and distributed energy resources that act as a single, controllable entity with respect to the electric grid.

Red Feather Lakes is vulnerable to wildfires, high winds, winter storms and car accidents on its winding mountain roads — all of which can take out a power line and cause extended outages. The microgrid is expected be able to provide the community up to 8 hours of electricity when other parts of the grid are unavailable.

The microgrid serves Red Feather Lakes community members, the library, a post office, local businesses and more. Community members and critical services such as fire response, EMS and telecommunications will experience better energy management and increased resiliency and reliability thanks to this innovative project.

Coming together with the small, isolated mountain community, Poudre Valley REA is proud of this community-focused initiative made possible with support from its power supplier, Tri-State Generation and Transmission, and other national partners.

LPEA Tests Grid-Integrated Technologies

Durango-based electric cooperative La Plata Electric Association, in partnership with 4CORE (Four Corners Office for Resource Efficiency), received access to funding through the Beneficial Electrification League to help local, income-qualified members obtain the latest electric water heating technology.

Select homes in the Animas View Mobile Home Park are now qualified to receive free installation of an air-source heat pump water heater and other energy efficiency measures, such as LED lighting, low-flow faucets and showerheads, and window and door weather stripping.

In addition to being remarkably efficient, the installed air-source heat pump water heaters will run on a schedule that avoids expensive peak power consumption. During times of peak electricity demand, LPEA will be able to remotely manage these water heaters, although this is expected to be a rare occurrence. This will not impact member homes (as water heaters store enough hot water for these short periods), and it will help LPEA avoid the purchase of expensive “on-peak” power from its power suppliers.

LPEA CEO Jessica Matlock said in a recent news release, “This innovative project will allow LPEA to test the viability of grid-integrated technologies to manage our local power demand.”

Participation in this program is voluntary, and the total number of homes included will depend on the matching funds LPEA is able to secure from other partners. This program will improve energy efficiency and is sure to reduce utility bills for residents. Installations are expected to begin February 2022.

Working Together to Combat Cyberattacks

By Paul Wesslund

Computer hacking is a top news story these days, and for years electric cooperatives have focused on blocking cyber threats from interfering with the nationwide electric grid of wires and poles that keeps our lights on.

The network of power lines, transformers and substations adds up to an incredibly complex system that reliably brings us the conveniences of modern life. That network is transforming into a “smart grid” these days. It’s adding renewable energy sources such as solar and wind, which call for sophisticated software to keep power flowing at night or when the wind isn’t blowing. Computer algorithms react with the most efficient and reliable operations when forecasts call for storms, wildfires or times of high-power use.

Making such modern miracles happen means joining with another dominant part of today’s world: the internet.

The blink-of-an-eye speed of balancing the generation of electricity with your flip of a light switch relies heavily on the electronically-connected world. The internet is incredibly useful, but also a target of troublemakers — from lone, self-taught experts to international crime rings.

Electric utilities know this and work every day through their own offices and national organizations on cyber safety.

You can take smart steps too, to protect yourself and the electric grid. Because the power grid uses the internet, that means any of your internet-connected devices are also part of the grid: computers, security cameras, printers, smart TVs, health monitors — even cars and lightbulbs can be connected to the internet.

Here are the top ways you can defend against hackers:

Lock the front door.
If you have wireless internet in your home, the traffic comes in through the router. If you take just one step, create a strong password for that router, and set a reminder to change the password regularly.

Use a secret code.
Weak passwords make things easier for hackers. Use combinations of uppercase and lowercase letters, combined with numbers and special symbols like “&” or “!”.

There are apps to help you remember passwords. A simple notebook can also work, as long as you never lose it and no one else has access to it. And be aware that every major internet-connected appliance comes with its own factory-installed password you should change right away.

Stay vigilant.
If you receive an email with an attachment you aren’t expecting, don’t open it. If you get a message with a link you didn’t know was coming, don’t click it. If the message is from a friend, phone and ask if they sent it — hackers can send messages using your friend’s address.

Stay state-of-the-art.
Your computer and other devices regularly offer updates — install them. They often contain security updates to protect against the latest cyber threat, so consistently check emails or messages saying you need to download an update. Go online and check any updates to your device to ensure they are authentic.

October is National Cybersecurity Awareness Month, and the U.S. Department of Homeland Security has titled this year’s theme, “If you connect it, protect it.” That’s good advice for your home — and for the electric grid.

Electric Buses Arriving in Rural Colorado

By Sarah Smith

Electric school buses are coming to rural Colorado. Not only do they reduce emissions and provide environmental advantages, but electric buses also provide health benefits to riders. Diesel vehicles emit tailpipe emissions linked to asthma, respiratory illness and cancer. Electric school buses do not emit exhaust, entirely eliminating these health risks. That is an attractive selling point when schools think about the well-being of students.

Representatives from West Grand School District, Mountain Parks Electric and Tri-State Generation and Transmission cut the ribbon for the district’s new all-electric school bus.

Currently, 95% of the state’s school buses run on diesel, but Colorado’s electric cooperatives are on a mission to change that statistic. Currently three Colorado co-ops, Mountain Parks Electric, in Granby, La Plata Electric Association in Durango and Yampa Valley Electric Association in Steamboat Springs, are trailblazers in providing electric school buses to their communities.

The first all-electric school bus in rural Colorado (and second in the state) made its grand entrance in Kremmling this spring with the help of MPE; its power supplier, Tri-State Generation and Transmission Association; and a grant funded by the Regional Air Quality Council’s ALT Fuels Colorado program. The West Grand School District is now reaping the benefits of switching to an electric school bus. Not only does this mean cleaner and quieter vehicles for students to ride in, but it will also significantly reduce fuel costs.

The small school district already budgeted to replace one of its buses with another diesel bus at a ticket price of $200,000. Although electric buses cost twice that amount — typically ringing in at $400,000 — after qualifying for the RAQC grant and the added contributions from MPE and Tri-State, the district received the bus at no cost. (MPE used capital credits unclaimed by previous members to help fund the new and improved mode of transportation.)

MPE is the first electric co-op in Colorado to help provide an electric school bus to one of its school districts. The electric bus means cleaner air for the entire community. It also saves thousands of dollars a year in maintenance and fuel costs. Currently, the power needed to charge the bus includes more than 30% renewable energy; the amount of renewable energy is projected to grow to 50% by 2024.

MPE spearheaded the funding and support of electric school buses, but LPEA and YVEA are not far behind.

LPEA was set to deliver the next electric school bus as the 2021 school year starts. The Durango School District 9-R received a grant also funded by RAQC to kick-start its project. The grant provided the school district $328,803 to purchase and install a fully electric school bus and related charging infrastructure. LPEA contributed an additional $150,000 to complete the project.

The environmental and health benefits, along with the annual cost savings, are all exciting advantages of securing the electric bus. Like the district in Kremmling, Durango was planning to purchase a new diesel bus to replace an old one in its fleet, but with the financial assistance of the grant and LPEA, it is receiving the bus at no cost to the district.

This particular bus will be the first vehicle-to-grid installation in LPEA’s service territory. LPEA will use a technology called bidirectional charging. This allows the bus to pull electricity from the grid during off-peak hours. But LPEA can reverse that flow and pull electricity from the bus onto the grid during critical times. It’s a win-win scenario for the school district and LPEA.

“The payback of installing this vehicle grid is compelling,” said Dominic May, the energy resource program architect at LPEA. “School buses charge very nicely off-peak. The timing works well with school buses because it avoids the evening peaks, and midday charging sessions also get maximum solar. Furthermore, charging these electric buses only uses one-eighth of the cost of diesel. By installing this grid, LPEA will inevitably make money back each year.”

The project is full steam ahead, and LPEA looks forward to unveiling the new electric bus to the Durango school district this fall.

In northern Colorado, the Hayden School District will be making the switch to an electric bus for its students this year. Steamboat Springs has been in the process of making the switch to electric buses in its city bus fleet. The town tested two electric buses to evaluate their mileage, emissions and safety and concluded that the electric vehicles were successful.

“We really see the benefits of electrifying many sectors, and transportation is one of them,” said Megan Moore-Kemp, energy solutions manager at YVEA. “Some of the benefits of electric buses to our citizens is that they do cost less over the long term; they’re less expensive to charge, fuel and maintain than gas-powered vehicles; and they cut emissions.”

When the Hayden School District approached YVEA about its plans to apply for the RAQC grant, YVEA happily wrote a letter of support. The co-op collaborated with the school board from an innovation standpoint, offering specifics on what a fair electric rate would be and exploring what infrastructure costs would look like. “YVEA believes this is a very important project and we were happy to collaborate with our partners to achieve their clean energy goals,” said Carly Davidson, public relations specialist at YVEA.

This is just the tip of the iceberg for electric buses in the state as other electric co-ops work toward bringing electric school buses to their communities. These electric vehicles will provide environmental and financial benefits to Colorado schools. Colorado’s electric co-ops are excited to be leaders in the process.

Colorado Co-op Works to Bring EVs to Low-Income Rural Areas

San Isabel Electric, headquartered in Pueblo West, joined the National Rural Electric Cooperative Association and 16 other electric cooperatives to apply for $8 million in federal grants to bring electric vehicles to low-income rural communities.

Most of the proposed co-op projects would install public EV charging stations at key locations such as low-income apartment complexes, medical facilities, parks and highway corridors, said Brian Sloboda, NRECA’s director of consumer solutions.

“In some cases, these would be the first public chargers that anyone in the community has ever seen,” he said.

The DOE will fund 50% of the cost of the projects, leaving co-ops and any community partners to pay the rest. The agency will announce a maximum of five winners at the end of the highly competitive process in October. The co-ops are competing as one unit, rather than as individual businesses, with NRECA as the project leader.

“I don’t think you can find another team that represents such a diverse group of utilities, projects and communities and that meets the ambitious goals of the Department of Energy,” Sloboda said.
Despite increasing interest in EV charging by for-profit companies, “few companies are building this infrastructure and trying to grow EVs in the rural areas except these non-profit, consumer-owned electric cooperatives,” he said.

“It’s a long-haul investment that’s not going to pay off overnight,” Sloboda said. “This is where we need the leadership from the DOE in recognizing the needs of these underserved rural communities. Without co-ops working with the DOE, we probably won’t see rapid progress.”
