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.

PVREA Middle-Mile Fiber Internet

Poudre Valley REA broadband power infrastructure will be seeing an increase in its resiliency soon. Larimer County has received a $995,429 grant from the Colorado Department of Local Affairs to help develop community-owned middle-mile fiber to the towns of Wellington and Masonville. Additionally, the county’s general fund will be matching the grant. While Larimer County is generally well-connected, this grant will be pivotal in providing improved access to unserved and underserved rural residents who have struggled with inadequate broadband infrastructure and unreliable service.

The middle-mile fiber project will include the construction of 107,168 feet of above-ground fiber on Poudre Valley REA poles, and will interconnect with existing community-owned middle-mile fiber. Wellington can expect to see improved connection both in town and in more rural areas, and this new fiber will connect with Fort Collins-based broadband service Connexion. The Masonville route will focus on improving connectivity along Larimer County Road 27 between U.S. Highway 34 and Masonville, which will create opportunity for last-mile expansion projects in collaboration with Loveland Pulse, Loveland’s fiber-optic internet provider.

The partnership between Connexion, Larimer County, and Loveland Pulse is focused on improving the community and providing excellent customer service, with Chad Crager, Connexion Broadband executive director stating “We believe that a great internet experience is the foundation for the future of innovation and collaboration in this region.” Each fiber service will own and be responsible for construction, maintenance, and operation of the new middle-mile project. Not only will this grant make improved connectivity possible for many homes, it also will help the community compete for future grants to upgrade infrastructure for years to come.

Holy Cross Energy Solar Array and Battery Storage Collaboration Project

Holy Cross Energy announced the completion of its new solar array and battery storage project at Colorado Mountain College’s Spring Valley campus in Glenwood Springs. This project is a collaboration between Holy Cross Energy, Colorado Mountain College, Ameresco, Sunsense and Friends. The utility-scale solar and storage project is a step towards Holy Cross Energy’s goal of producing 100% carbon-free electricity by 2030, as well as Colorado Mountain College’s intention to be entirely carbon neutral by 2050.

The system includes 13,500 solar panels located at the campus, which provide 4.5 MW of solar power, and 68 battery stacks that provide 5MW/15MWh of battery energy storage. Most of the solar panels are installed using single-axis tracking, which uses one axis of rotation and takes advantage of the different terrain and space constraints of the site. The 68 battery stacks are stored in four on-site containers, each of which also contains an HVAC system to control temperature and humidity. Fire suppression measures are in place for further safety. The batteries will be used to store energy, discharging it during peak demand hours to reduce overall energy costs and save money for Holy Cross Energy members.

Sam Whelan, Holy Cross Energy’s Vice President of Power Supply states “The HCE/CMC solar plus storage project is a great example of a win-win renewable project. Not only does the project assist both HCE and CMC toward their renewable and carbon goals, but the battery also provides us with the flexibility to operate an increasingly renewable portfolio. To top it all off, we’re able to do this in a financially responsible way that saves money for all our members.”The annual offset of greenhouse gas emissions from this project is 6,853 metric tons of carbon dioxide equivalent, or the same as removing 1,481 passenger vehicles from the road or saving 7,551,051 pounds of coal every year. Three CMC campuses, including Vail Valley, Aspen, and Spring Valley, will receive power from this new installation.

Holy Cross Energy Completes First Phase in Broadband Infrastructure Project

Holy Cross Energy announced that Phase I of their broadband infrastructure project in the Roaring Fork Valley is complete. The three-phase project brings “middle mile” broadband infrastructure to several communities in both the Roaring Fork Valley as well as the Eagle River Valley. Middle mile infrastructure is, according to the Colorado Broadband Office, “The telecommunication network of robust, high-speed fiber or fixed wireless that brings broadband close enough to a residence or business so an internet service provider may provide internet access. Middle mile connects to the global internet backbone.” This improved infrastructure plan also serves to diagnose outages, dispatch energy resources in real-time, and increase reliability between Holy Cross Energy data centers in an emergency.

Phase I of the project improves fiber connectivity over a 41-mile stretch between Glenwood Springs and Aspen. Construction of Phase II begins later this summer, connecting Avon and Gypsum, and Phase III will connect the first two phases with a link over Cottonwood Pass. Holy Cross Energy’s fiber and broadband director, Manuel Gomez, states “HCE’s primary goal is to increase reliability and to dispatch energy resources in real-time. We are also excited to utilize our fiber where available to support our member and communities by providing access to a strong fiber network.”

The decision to pursue middle mile projects was made by the HCE board of directors to support systems operations and increase connectivity to the community. Holy Cross Energy will not provide retail internet services, but instead has partnered with both public and private entities to increase fiber infrastructure by subleasing the fiber network to regional internet providers. As of today, the only lease on HCE’s fiber infrastructure is through a partnership with the Northwest Colorado Council of Government, which provides middle mile broadband services to Pitkin County, the City of Aspen, the Town of Basalt, and the Town of Snowmass Village.

MCREA Uses VR Technology as Part of Safety Program

An innovative use of technology is giving Coloradans on the eastern plains invaluable and unique experiences to learn how to properly approach electrical safety. Morgan County REA now includes virtual reality headset technology as a part of its safety training program. Wearing a VR headset allows a user to experience virtual simulations that are designed to create an immersive environment. The virtual experience elicits the same stress response as some real-life situations, so if the individual is faced with the same scenario in real life, they are prepared and know how to handle the situation safely.

One of the scenarios the Fort Morgan-based electric co-op offers in their VR safety training is downed power line safety training. The simulation puts the user at the scene of an accident where a vehicle hits a power pole and the power line has fallen on the car. The user learns what steps to take to safely remove themselves from this dangerous situation. Another training simulation available through the VR headsets includes farm hazards. Users can participate in a variety of tasks on a farm and the VR experience educates them about how to handle unexpected situations. In April, personnel from the Southwest Washington County Fire Protection District also implemented the use of MCREA’s VR headsets as part of their staff training program for power line safety.

One of the benefits of utilizing VR technology as a safety training tool is the high retention rate. Because individuals have already mentally experienced the scenario, it is easier to recall important information. A study by the Masie Report shows that VR simulations have a retention rate of 75%, significantly higher than the 10% retention rate from reading and the 5% from listening to lectures. A high retention rate is crucial in safety training, when keeping individuals from harm is the top priority. Hands-on experience is the best education, and the addition of this interactive tool will contribute to a more comprehensive safety program moving forward. The implementation of VR technology at MCREA will be beneficial for the co-op and its members. For more information, visit mcrea.org.

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.
