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.

Holy Cross Announces Completion of Solar Project

Primergy Solar, LLC, recently completed construction on the Pitkin Solar Project in the Roaring Fork Valley. The 5-megawatt installation consists of approximately 13,700 solar panels that include innovative bifacial panels and tracking systems.

Under a 25-year power purchase agreement, energy from this project will be sold to Holy Cross Energy. The Glenwood Springs-based electric cooperative estimates this solar site will generate enough electricity to power about 900 homes and will give consumer-members of the co-op access to locally-generated renewable energy.

HCE President and CEO Bryan Hannegan stated in recent press release that this project “is an important step on our journey to 100% clean energy.”

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.

Cooperation Among Cooperatives Addresses Wildfire Mitigation

Seeking solutions to be proactive about wildfire prevention and mitigation strategies, San Luis Valley Rural Electric Cooperative looked at Brighton-based United Power’s previous fire mitigation work. The electric co-op based in Monte Vista replaced three-phase line and 34 poles in parts of its service area with Hendrix Aerial Cable. United Power switched its power line to Hendrix Cable in its mountainous Coal Creek Canyon service area in September 2020 and invited SLVREC to review its projects.

Hendrix cable is an insulated conductor and provides a high level of protection in the event that a tree falls onto and makes contact with a power line. With the stronger, covered cable, the risk of wildfire caused by electrical equipment is drastically reduced. Hendrix cable also withstands severe weather events, helping prevent outages if the line is struck by a tree.

This innovative use of collaboration and infrastructure materials offer the benefits of wildfire prevention and improved reliability for co-op consumer-members. And it’s another example of an important cooperative principle at work: cooperation among cooperatives.

Southern Colorado Co-op Launches New EV Station

Durango-based electric cooperative, La Plata Electric Association, partnered with Purgatory Resort to install a new EV fast-charging station for public use. This new station is part of the Colorado Energy Office’s EV fast-charging corridor project and completes the charging corridor that runs through LPEA’s service territory.

To launch the station, LPEA and Purgatory Resort hosted a ribbon-cutting ceremony on Wednesday, September 1.

“We are thrilled to have completed our portion of the statewide EV fast-charging corridor, which will allow EV drivers to traverse Colorado, from corner to corner, without range anxiety,” LPEA CEO Jessica Matlock said in a news release.

Installed with funds from Colorado Energy Office and LPEA, the station is open 24 hours per day and costs 30 cents per kilowatt hour. An idle fee of 30 cents per minute is also charged when a vehicle is left plugged in longer than 10 minutes after charging is complete. Unlike standard level 2 EV chargers, which take 3 to 8 hours for a full charge, level 3 DC fast chargers take less than 30 minutes.

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.”

New Substation to Support Growth in Franktown

CORE Electric Cooperative (formally Intermountain Rural Electric Association) is building a new substation in Franktown to serve load growth between its existing Bayou and Castle Rock substations.

The new 115-kilovolt to 12.5-kilovolt facility will provide reliable power to the area and help relieve the co-op’s Bayou and Castle Rock substations. The project started in mid-May and the co-op anticipates construction will be completed by December. The substation is expected to be in operation by February 2022.

The Sedalia-based electric cooperative serves over 160,000 consumer-members across its 5,000-square mile service territory. In addition to this new substation, the co-op plans to build 12 feeders over the next three to five years as additional load is added to the system.
