Electric Co-ops Get Creative with Carbon Emissions
Tri-State Generation and Transmission, a power supplier for 18 of Colorado’s 22 electric cooperatives helped dedicate the Dry Fork Station Integrated Test Center on May 16, 2018. The ITC is host to the Carbon XPRIZE, in which participants compete for a total of $20 million in prize money. The goal for the XPRIZE is to incentivize the creation of commercial commodities from CO2 emissions in an effort to create a circular carbon economy. In 2016, coal-based generation facilities produced more than 1.2 metric tons of CO2.
The ITC project occupies over 200,000 square feet of space at the Dry Fork facility in Wyoming. The Carbon XPRIZE finalists will use one of five test bays, and will share access to flue gas produced by 1.5 MW of generation capacity from the coal plant.
Tri-State contributed $5 million to the ITC project after identifying the need “to provide venues for innovators to bring new [carbon utilization] technology forward,” according to Ellen Connor, senior vice president and chief technology officer at Tri-State.
XPRIZE finalists are proposing products like feedstock, foamed plastics and concrete — all created by using CO2 emissions from the coal plant. CREA will continue to track the XPRIZE and how solutions from forward-thinking innovators will trickle down to Colorado’s electric co-ops.
Colorado Co-op Innovates with Nest Thermostats
United Power, Inc., announced in May that all members qualify to receive savings by purchasing and using a Nest programmable thermostat.
The Brighton-based electric co-op now offers member rebates for new Nest purchases, as well as through a program called “Rush Hour Rewards” for members who have a Nest thermostat and central air conditioning. It will help the co-op decrease peak power usage during hot summer days when members’ collective air-conditioning use is high, thus relieving some of the load on the electric grid during those times.
Prior to a “Rush Hour” of energy usage, members’ qualifying Nest thermostats will pre-cool the home. Nest-using members will receive a message directly from the app saying that United Power has scheduled a Rush Hour because predicted electricity use is high. Then members’ Nest thermostats will automatically adjust up or down a few degrees. When the Rush Hour is over, the Nest thermostat will automatically return to its regular temperature schedule.
Rush Hour Rewards rebates are applied as United Power bill credits. Members will receive $50 upon enrollment in the Rush Hour Rewards program, and then an additional $25 at the end of the summer when they stay enrolled for the season.
Keep up-to-date with this innovative approach to saving energy and members’ money with the CREA Innovations in Energy newsletter. We are anxious to see how more Colorado electric cooperatives innovate with smart home devices.
Mountain Parks Electric Builds New Solar Array
The board of directors for Granby-based Mountain Parks Electric, a nonprofit electric provider, approved the purchase of electricity from a 1.3-megawatt solar array to be built in Jackson County. Microgrid Energy plans to construct the solar array several miles north of Walden, just east of Highway 125. MPE will purchase the solar generation for 20 years after the array is constructed.
The electricity generated from the array is estimated to produce enough electricity for 300 homes. Mountain Parks Electric “will save money on wholesale power costs with every kilowatt-hour generated by this solar array,” says Tom Sifers, MPE general manager.
Other renewable energy projects in MPE territory include hydroelectric generation from the Granby Dam, Grand Lake’s micro-hydro recovery system and the Williams Fork Dam. This solar generation array will add to the local renewable power supply, increasing it their renewable portfolio, which currently stands at 30 percent.
Co-op Power Suppliers Evolve to Meet Future Needs
by Amy Higgins
Electric cooperatives are committed to making reliable and low-cost electricity available to consumer-members. To do that, many co-ops depend on their generation and transmission co-ops (G&Ts) that supply the electricity. Those G&Ts are finding new ways and new resources to help their co-ops meet the needs of their members today and tomorrow.
“G&Ts have expanded their supply portfolio to add cleaner and more efficient modern natural-gas fired generation and renewable resources, and are also investing in emerging technologies,” said Paul Breakman, senior director in NRECA’s business and technology strategies (BTS) department.
“The nation’s 63 G&Ts (including Tri-State Generation and Transmission Association in Colorado) are finding ways to support infrastructure opportunities and replace existing generation to ensure electric co-ops have access to the lowest cost electricity available,” said Dan Walsh, senior power supply and generation director for BTS. “G&Ts are investing millions of dollars each year into research, plant modernization and new generation.”
The Earth’s Energy
Owned or purchased renewable energy capacity available to electric cooperatives has topped 9 gigawatts, with at least another 1.1 GW planned by 2020, excluding about 10 GW of federal hydropower purchased by co-ops each year.
Fueling the projected growth are a number of factors, including the extension of federal tax incentives and the improving economics of renewable resources.
With 85 megawatts of solar, Westminster-based Tri-State Generation & Transmission leads the nation in co-op solar power, according to Lee Boughey, Tri-State’s senior manager of communications and public affairs. The G&T supplies electricity to 18 of Colorado’s 22 electric co-ops. In 2017, 30 percent of the energy consumed within the association came from renewable resources.
Tri-State’s first two large, utility-scale projects were announced in 2009 and came on line in 2010: the 30-megawatt Cimarron Solar facility located in Colfax County, New Mexico, and the 51-megawatt Kit Carson Windpower Project in Kit Carson County, Colorado. “Since then, Tri-State has added two additional solar projects, which make our association the top G&T in the nation for solar power,” Boughey said.
With three wind projects in eastern Colorado and six hydropower projects, Tri-State has 475 MW of renewable projects in its portfolio. “Those projects are complemented by our members’ local renewable projects and the hydropower power the association purchases from the Western Area Power Administration,” Boughey said.
There have been significant decreases in the cost of renewable power since the G&T’s first projects were signed on in 2009. As a result, its recent renewable energy power purchase agreements benefit its member systems with the lower cost of energy. Projects that came on line in 2017 include the Alta Luna solar project in southern New Mexico and the Twin Buttes wind project in southeast Colorado.
“While other utilities across the country have seen decreases in the demand for power, Tri-State, which has a diversity of member systems, continues to experience load growth,” Boughey said. In 2017, the amount of energy the G&T supplied to its members increased more than 2 percent.
And more of that power is now generated using renewable resources.

Sunshine in Southeast Colorado
After two years of analytical research, planning, development and construction, Colorado electric co-op Southeast Colorado Power Association energized the Vilas Solar site on March 1.
A partnership with RES, the solar project will provide solid energy output. The La Junta-based co-op will pay RES for the energy output from the solar site on a pre-determined pricing model. And since solar power is relatively easy and cheaper to produce, members will see cost benefits over the next 20 years.
The solar project sits on almost 40 acres near Springfield. This is the first local solar project for SECPA and the co-op is excited to add this solar source to its renewable power generation portfolio.
D.C. Conference Focuses on Broadband
The National Rural Electric Cooperative Association Legislative Conference took place in Washington, D.C., the first week in April and Colorado co-ops attended to meet with legislators. The annual conference gives rural electric cooperative leaders the opportunity to discuss co-op priorities and legislation that directly affects co-ops and rural America. This year, one of the topics was broadband for rural America.
Work on the House Farm Bill and expanding funding for rural broadband was discussed by Agriculture Secretary Sonny Perdue, who was the keynote speaker at the NRECA conference. “Rural broadband is not just a luxury — it’s essential,” Perdue told more than 2,000 electric cooperative leaders attending the conference in Washington on April 9. “I don’t believe that America would ever reach the productivity we have today across our nation without abundant flow of electricity everywhere,” said Perdue. “In the same way, we cannot make America great again without high speed e-connectivity available to every American.”
Broadband access will improve rural education, medical care, communication and business, including farming, he continued. Perdue described how smart technology can drive precision fertilization and seeding at large farms. “You can’t do that without broadband e-connectivity,” he said.
Perdue said that the USDA is working now to distribute $600 million in rural broadband grants and loans, which has the potential to directly impact rural parts of Colorado. Several Colorado co-ops are currently innovation leaders in expanding high-speed internet into underserved parts of rural Colorado.
Electric Co-op Makes Technological Strides
“Forward-thinking and proactive” are two ways that Dan Harms, manager of rates, technology and energy policy at La Plata Electric Association, describes the Durango-based electric cooperative.
Technological advances in battery storage, increased individual solar systems and electric vehicle home charging popularity put LPEA in the top percentage of rural electric cooperatives across the country. This use of the latest technology benefits its members by maintaining reliability and efficiency.
The co-op also uses advanced computerized technology to track the territory system and outages. Dispatch has a “live” wall that monitors all parts of the system 24/7 in real time and the line crews use smartphones and tablets in the field for maintenance, inspections and repairs.
This innovative use of technology allows LPEA to serve the membership better while keeping rates low.
Co-op Grant Gets to the Core of History and Promotes Sustainability
Nucla-based San Miguel Power Association, CoBank and power supplier Basin Electric awarded the Apple Core Project with a “Sharing Success” grant. The grant from these three cooperative sources will assist in the installation of a demonstration orchard at the Pinion Farm Homestead in Nucla.
The Sharing Success grant seeks funding opportunities that will stimulate and enhance the local economies by job creation in the area, creating and improving local commerce, offering sustainability progress and building collaboration.
The funds from this particular Sharing Success grant will aid in planting hand-grafted apple trees in the demonstration orchard. According to the Apple Core Project’s website, “Each tree planted [in the demonstration orchard] will become part of a new generation genetic bank from which [the Apple Core Project] will collect the scion for grafting additional trees to plant.”
The Apple Core Project aims to identify and map fruit tree varieties on the Western Slope; to discover the stories of the people who planted and cared for these trees; to propagate local and rare fruit genetics by grafting and planting new trees in the area; and to revive the fruit growing economy on the Western Slope.
The Sharing Success grant is just one way that SMPA uses resources in an innovative way to help members support the local community. Visit applecoreproject.org for more information about the demonstration orchard and for interesting historical facts about the fruit industry on the Western Slope. Visit smpa.com to learn more about how the electric co-op supports their community.
Ski and Sun in the San Luis Valley
San Luis Valley Rural Electric Association, a Monte Vista-based electric cooperative, is proud to power the thriving Wolf Creek Ski Area with solar power. Ski lifts and buildings at Wolf Creek came on line with the Penitente Solar Project in November 2017. The ski area is the largest consumer of power in the San Luis Valley territory in the fall and winter months, both day and night.
Penitente Solar is a 2.75 AC megawatt solar project that sits on a sunny, unobstructed location less than a half mile from SLVREC’s La Garita Substation. SLVREC negotiated a long-term power purchase agreement with Renewable Energy Systems. RES operates and maintains the distribution of the photovoltaic system, from which SLVREC purchases the output to serve members’ electricity needs. This project provides power to the Wolf Creek Ski Area and to co-op members in Saguache, Rio Grande, Costilla, Alamosa, Conejos, Mineral and Hinsdale counties. Residential members get access to renewable energy that is locally generated and cost-effective.
The annual output of the solar plant is about 7,000 kilowatt-hours. Wolf Creek uses approximately 1,000 kilowatt-hours each year. The expected operational lifetime of the project is more than 25 years, benefitting skiers and members alike well into the future.
Mountain Co-op Opts to Build Fiber Backbone
Nationwide, electric cooperatives install automated metering systems, energy efficiency and demand response programs, and grid monitoring systems that all require real-time communication in order to provide members the safe reliable electricity they are accustomed to receiving 24 hours a day. As technology advances in the electric industry, cooperatives are requiring more sophisticated telecommunications technology.
A such, electric cooperatives — as well as their members — need access to fast and reliable high-speed internet service for system management, work, video conferencing, entertainment and to stay relevant and connected to the world. Studies still show that rural Americans are less connected than their urban counterparts due to limited or no access to high-speed internet.
In a recent survey to members of Granby-based Mountain Parks Electric, Inc., the electric co-op reports that members agree that low-cost, high-speed internet is “very important to the future of the local economy.” In response to survey results, the MPE Board of Directors has weighed two business cases for becoming a retail internet service provider, which prompted two feasibility studies.
Both studies proved that there would need significant capital investment. One study estimated a cost of $95 million for MPE to form, construct and operate a “last-mile” (retail) internet service. The area’s rugged terrain, and its sparse population are the biggest factors in this cost estimate.
When the electric co-op formed in 1946, nearly 100 percent of households in the territory signed up for electric service. In contrast, the internet feasibility study revealed that only about 45 percent of current electric co-op members would sign up for retail internet service through MPE.
With those lower numbers is the potential for members to see an increase in electricity rates if MPE were to move forward with the retail internet project. The MPE board is not eager to impose such rate increases on co-op members.
However, the board of directors is still convinced that high speed internet is a need in the community it serves. As such, at the February meeting the board adopted a motion to improve internet access in a more cost-effective manner. Instead of building an expensive retail service, the board moved to construct a “middle-mile system.”
A middle mile system is the backbone of a high-speed internet network. Once constructed it will allow for immediate electric utility operational improvements. An MMS backbone investment will not significantly impact MPE’s electric rates to members. MPE also reports that the backbone will position the co-op to implement technologies that may help manage future wholesale power costs, benefiting all members.

3,000 Pounds of Recycled Lights Benefits Local Nonprofit
Sedalia-based Intermountain Rural Electric Association held its first-ever holiday light recycling program. It was hugely successful and co-op members brought in much more than expected — over 3,000 pounds of recyclable holiday lights. IREA took the lights to Western Metals Recycling center where it was paid 20 cents per pound to recycle the lights.
This was a chance for members to recycle their old holiday lights at no cost, and the program provided a donation to Energy Outreach Colorado. IREA matched the amount received from the recycling center, making the donation total over $1,200. Energy Outreach Colorado helps low-income Coloradans with heating bill assistance, emergency home furnace repair and grants to improve the energy efficiency of affordable housing facilities.
This recycling program is an innovative way to encourage members to dispose of holiday lights in a responsible manner, and also provide funds to help Coloradans.
Co-op Rebates, Updates Help Local Businesses Shine
Since January 2018, Colorado electric co-op, Empire Electric Association, has presented over $15,700 in rebates to 10 local businesses that built, updated or retrofitted their spaces with LED lighting.
A new cider brewing company in Mancos outfitted its tasting room lighting with LED pucks for a pleasant and inviting look and feel. It also installed bright LEDs in the brew room’s high ceilings for an efficient and well-lit workspace.
LED horticulture lights are now installed at The Herbal Alternative, which save on energy and are passively cooled. Less heat is generated by LEDs compared to the old lighting, helping to maintain the correct temperature for the plants.
In another retrofit, 6500 Kelvin lighting brought new sparkle to an antique store in Cortez, updating the space with bright white lights.
Steve Keetch Motors retrofitted existing showroom fixtures with LEDs, as well as placing them in the service garage, offices, waiting room and restrooms. These efficient bulbs make lighting spaces more efficient and cost-effective.
Denise Moore, EEA’s communications specialist takes photos of the rebate check presentations to share on social media and says that the co-op “Has enjoyed featuring business in our area that take advantage of our rebate program.” This thriving program is just one way that the Cortez-based co-op helps commercial members save money and develop more efficient spaces.
Mountain Co-op’s Green Power Rebates
Granby-based Mountain Parks Electric members who installed renewable energy systems received nearly $21,000 in total rebates in 2017. This is the program’s biggest rebate year yet, increasing from $14,490 in 2016.
The electric co-op started the Green Power program in 1999, then purchasing renewable energy credits on behalf of customers who wanted to support the development of renewable energy sources. In 2011, the course of the program changed to a thriving rebate program that rewards members who install local renewable energy projects at their home or business, with the goal to facilitate more green power projects. This increases the amount of renewable energy that the co-op can offer to members.
The project is funded by members’ voluntary additions and contributions to their monthly electric bill, ranging anywhere from 50 cents to $100 a month. Rebate levels are generous, with the residential rebate at $1,000 + $0.10 per DC watt ($2,000 maximum) and the commercial rebates at $1,000 + $0.10 per DC watt ($8,000 maximum).
Colorado Co-op Brings LEDs to Businesses
Sam Christensen, owner of a home furnishings store in downtown Durango, retrofitted his poorly lit showroom with LED bulbs. Durango-based La Plata Electric Association’s project specialist Ray Pierotti advised Christensen on which bulbs to buy to transform his store into a bright and colorful retail space. Pierotti also helped the retailer process rebates on the commercial-grade LED bulbs.
Christensen spent $1,163 on the bulbs and received a rebate of $592.57 directly from the co-op. He will save about $1,400 annually on his La Plata Electric Association electric bill, resulting in a return on the LED investment in less than six months.
Pierotti reports that more than half of Durango’s downtown businesses are 100 percent LED lit. He encourages retailers and business owners to contact him directly before they upgrade lighting or do a store redesign.
This is just another example of how Colorado co-ops help residential and commercial members make the most out of their electricity use using all resources available.
Gunnison Co-op Promotes Efficiency Innovations
Infrared thermography imagery is a fast and accurate way to find suspect areas around homes and businesses where electric efficiency is less than ideal.
In an innovative approach, Colorado electric co-op Gunnison County Electric Association has provided IR energy audits to its members since 2011 and it continues to offer this service today.
Not only can the IR audit solve efficiency issues in residences and businesses — like improper or missing insulation in ceilings and walls — it can find other issues not related to the building construction or insulation. GCEA’s energy use specialist Alantha Garrison reports that IR audits have also discovered radiant in-floor or in-ceiling heating systems that the member did not know existed.
High electricity bills can be of concern for many consumers, and GCEA uses these high-tech energy audits to help find problem areas that can contribute to that issue. These audits help inform members as well as lower their bills.
Efficient Lighting for Fire Station in Co-op Territory
In an innovative effort, Colorado electric co-op San Miguel Power Association in Ridgway was called on to help brighten and increase efficiency at the Norwood fire station in southwestern Colorado. Fire chief Joe Conway took advantage of the expertise and rebates offered by SMPA, his local electric co-op, to upgrade the lighting of three truck bays, several personnel offices and a meeting/training room which is also used by the community.
These spaces were formerly outfitted with 40-year old lighting technology, but thanks to the help of the co-op and volunteers, the lighting redesign will be more efficient for the fire station, benefitting both the personnel and the community that uses the space.
The lighting project will reduce the energy requirement by 15,000 kilowatt-hours a year and reduce the station’s annual bill by approximately $2,000. This upgraded investment will pay back in less than one year with the SMPA rebate.
SMPA works directly with both commercial and residential members to take advantage of their rebate programs.
Colorado Centennial Farm Installs Micro Hydro Project in Co-op Territory
With a goal of generating 40,000 kilowatt hours, about the same amount that his center pivot sprinkler uses, Jim Park installed an innovative micro hydroelectric project on his corn and alfalfa farm in Weld county.
Typically seen on the Western Slope, agricultural hydroelectric projects on the eastern plains and the Front Range are still gaining popularity and traction. After his 20-year service as a Poudre Valley REA board member, and the owner of a 260-acre Colorado Centennial Farm, Park was knowledgeable and interested in hydroelectric generation.
After receiving coordinated grants from the Colorado Department of Agriculture, the U.S. Department of Agriculture Rural Development and the USDA’s Natural Resources Conservation Service, Park ordered a cross-flow turbine generator from the Ossberger company based in Germany. Park placed the turbine at the bottom of a 25-foot slope in his irrigation diversion off the Lower Latham ditch. The turbine was manufactured specifically for his land elevation, water volume and generation needs. The ditch runs from April to November and the turbine began generating power in June 2017.
Park will eventually see a positive return on his investment, and if the unit generates more energy than needed to run his sprinkler, a portion of the overage will be treated as a savings on his electric bill through PVREA.
Fort Collins-based PVREA cooperative partnered with Park for this project and provided him the interconnection for it to come back to his metering.
Co-op Upgrades Power Lines During Wildfire Rebuild
Wildfires ravaged northwestern Colorado this summer, with at least three fires in Routt and Moffat counties. Steamboat Springs-based electric co-op, Yampa Valley Electric Association experienced the harsh effects of the lightning-caused Moffat County Pine Tree Fire, which was not well-contained until mid September and the Winter Valley Fire, which was spread quickly due to 50 mile per hour winds.
The Pine Tree Fire caused significant damage to the YVEA power system. Fire officials allowed co-op crews into parts of the 4,700 acre burn area to assess the damage to their lines and equipment.
YVEA had over 30 members without power due to the fire, but the co-op crews and contractors worked in extreme and challenging conditions to restore and replace the damaged infrastructure to their system. In addition to the 2 to 3 miles of overhead line that needed to be repaired, there were 33 utility poles that needed replacement, 13,200 feet of damaged aluminum conductor cable and two melted meters. The repairs will strengthen the transmission system and increase reliability in that area. The Winter Valley Fire, which spread to 7,800 acres, took out the three-phase line into Lily Park.
In both cases, the system was rebuilt with shorter spans between poles and an improved and strengthened infrastructure. This will mean fewer outages for members in these areas going forward and better reliability.
Innovations at Co-ops Reported at Federal Hearing
Glenwood Springs-based Holy Cross Energy CEO, Dr. Bryan Hannegan, was a valuable witness representing rural electric cooperatives at the Energy Subcommittee Powering America Hearing, held by the U.S. House Committee on Energy and Commerce on September 26. The goal of this hearing was to provide insight into the nation’s electric grid and electricity markets and how rapidly-evolving technology innovations have a role in empowering consumers by giving them greater control.
During the introduction of the hearing, Chairman Rep. Fred Upton (R–MI 6th District) stated that the United States electric grid has been transforming in a way that allows consumers to become active market participants, in which they expect control, convenience and choice. The hearing and the testimony from the panel of witnesses shed light on the challenges that prevent advanced energy technologies from deploying around the country.
The panel—including Dr. Hannegan— reported that although the electric industry is regulated to ensure that all Americans have access to reliable and affordable electricity, changing technologies require a grid that allows two-way flows. Several members of the panel emphasized that battery storage and microgrids provide grid resiliency and localized solutions to keep electricity reliable and affordable.
When asked a question by a subcommittee member about the advantages for microgrids in rural areas, Hannegan replied that microgrids improve reliability and service, especially during natural hazard events, such as the snowstorms Holy Cross experiences in their service territory. He pointed out that microgrids are always helpful in addition to grid supply and that local generation solutions are a better option in those situations.
Dr. Hannegan reminded the subcommittee that infrastructure is important in light of the wildfires and hurricanes around the nation that recently compromised electric stability, especially in Puerto Rico. He also emphasized that local decision-making must “remain paramount” and that electric regulations are not a one-size-fits-all situation. He explained how rural electric co-ops have a small employee base, how their linemen work differently because of technology, how their member service staff will want to rethink how they interact with customers who have a choice in their electricity needs and how all of those factors may lead to a new look at the standard co-op principles. Despite these challenges, he still thinks that innovative and evolving technologies are exciting because it gives co-ops access to solar and wind where the “price points are nearly a wash.”
With “no shortage of feedback from co-op members,” Holy Cross is aware that members will ask for electricity innovations that they’ve read about or have seen on television. And since electric co-ops are “heavily embedded in the communities they serve,” the feedback the co-op receives “forces a pace of innovation on the co-op.” Hannegan was quick to point out that the challenge of co-op boards is to make sure they strike a balance of what co-op members want and what makes fiscal sense.
He spoke to the fact that the architecture of the grid is changing from a hub and spoke model with passive consumers to “a dynamic decentralized and distributed grid” via digitization, metering data and software developments. He pointed out that co-ops are naturally consumer-centric being member-owned nonprofit distributors. He told the committee that even with rapidly-changing technologies, co-ops will continue to prioritize the needs of their members while developing and deploying the technologies to provide safe, affordable and reliable electricity.
Eastern Colorado Co-op SCADA/AMI Team in Capable Hands
Reliability and timeliness are what drives Fort Morgan-based Morgan County Rural Electric Association’s SCADA/AMI team. Led by Ray Mann, the team monitors outages through the system, which allows the co-op to proactively deal with power outages quickly — in some instances, even before the member knows the power is out.
SCADA — supervisory control and data acquisition — is a control system architecture that uses technology such as computers and other peripheral devices including programmable controllers to interface with electrical substations. AMI — advanced metering infrastructure — are electrical meters in homes and businesses that measure electrical consumption, and also can communicate with the MCREA network to report measurements. The hardware and software monitor the electrical infrastructure throughout MCREA’s service territory and communicate system status to the control center at MCREA headquarters.
Not only does the system technology restore power quickly, the issue can often be resolved without having to send a serviceman or lineman to the location of the outage. This has the potential to cut vehicle use and fuel consumption, as well as save the cooperative labor costs.
Mann reports that even with the upgraded technology, communication from co-op members is still extremely important, especially in widespread outages. MCREA even has a texting service for members to report outages, which further promotes their innovative approach to serving co-op members.
Helicopters Help Co-ops Minimize Impact on Environment
The Cotopaxi and Texas Creek areas had extra air traffic this summer, but minimal impact on the local, mountainous terrain, thanks to the local electric co-op. The same was true on the Western Slope when a helicopter was used for power line inspections.
It was Sangre de Cristo Electric, headquartered in Buena Vista, which brought the helicopter to the mountain sides along the Arkansas River. The co-op needed to set four 900-pound poles, but the difficult and fragile terrain prevented safe access with typical co-op equipment. So, the helicopter was called in and the job was completed.
Colorado electric cooperative, Delta-Montrose Electric Association, also recently recruited the help of a helicopter to conduct line inspections across its service territory. The aerial patrol program helps DMEA inspect lines on parts of the power system that are difficult to reach in mountainous terrain. Crews in the helicopter scan for damaged equipment and linemen ride along to look for other potential problems before they cause outages. Damaged equipment can heat up, so hot spots are identified from the helicopter above through thermal imaging equipment
More than 3,000 miles of power lines will undergo aerial line patrol this year as part of DMEA’s system reliability program. Inspections help ensure safe and reliable power to homes and businesses across the DMEA service territory.
This use of helicopters is another example of how Colorado co-ops are always looking ahead to find innovative approaches to providing safe, low-cost, environmentally-friendly electricity to their service territories.
NEED & Power Supplier Educate Educators
In June, the sixth annual Tri-State Energy Conference brought together 45 educators teaching grades 4-12, and who are electric cooperative members or teach at schools that are within Tri-State’s member cooperatives’ service areas. Tri-State Generation and Transmission Association is the power supplier for 18 of Colorado’s 22 electric co-ops and 21 other electric co-ops in Wyoming, Nebraska and New Mexico.
The program, hosted at Tri-State’s headquarters in Westminster, CO, was offered in partnership with the National Energy Education Development Project. NEED works to promote an energy conscious and educated society through multi-sided energy education programs. Tri-State and NEED have partnered since 2012.
The three-day conference hosted applicants from Colorado, Nebraska, New Mexico and Wyoming, and provided the educators with cutting-edge industry information regarding the science of energy, sources of energy, transportation, consumption, electricity, efficiency and environmental and economic impacts.
Participants worked their way through six innovative, hands-on stations that each represented a different lesson, with the goal to learn how to teach energy in the classroom or during after school programs. “The curriculum is designed to integrate energy and STEM into the classroom,” explained Michelle Pastor, Tri-State’s education program advisor.
Each teacher received professional development credits and the participants walked away with a Science of Energy kit to use in their classrooms which “Includes hands-on activities for kids to do that all relate to energy education,” Pastor said.
Teachers reported that they learned about the conference via social media and Colorado Country Life magazine, the statewide trade publication of the Colorado Rural Electric Association.
Co-ops Research Electric School Buses
Colorado’s electric co-ops are part of a national organization that does energy efficiency research and are watching as two power cooperatives in Minnesota take the lead in advancing clean and efficient student transportation.
There are already 90 electric school buses in the North America, one of which will run in Minnesota starting this fall for the 2017-2018 school year. Great River Energy and Dakota Electric Association have partnered with Schmitty and Sons, and are working on securing two more for their school districts in their rural service territories. Cooperatives serve more than 8,000 of the United States’ 13,325 school districts, meaning partnerships like this one between electric co-ops and school districts could provide a nationwide model going forward.
The upfront cost of these electric vehicles starts at $325,000, but the potential savings in maintenance and fuel costs each year will be upwards of $10,000 per bus.
The eLion school bus seats 72 students, and is 100 percent electrically powered. This specific model can go 100 miles, and with the average school bus route in the United States being 60 miles, there is enough range for these electric vehicles to do many of the bus routes (even in cold weather) without having to charge in the middle of the day. It takes four to six hours to charge the bus, and most will charge overnight while taking advantage of lower electricity demand.
Colorado Utilities Rank in the Top Ten for Grid Modernization
Traditionally a “one-way street,” the U.S. electricity grid is changing and becoming an exchange network, with growing numbers of consumers also generating electricity on a small scale that contributes to the grid. This is referred to as a transition to grid modernization and can offer many benefits to Colorado electric cooperative members.
A 2017 CETC study on grid modernization ranked Colorado utilities in the top 10 among 16 states that took action to study or investigate grid modernization issues, energy storage and demand response. And rapid advancements in technology can contribute greatly to the electric system, benefiting both utilities and consumers if done right.
The nationwide deployment of advanced grid technology such as advanced metering infrastructure or AMI has been underway for several years with electric co-ops leading the way. In Colorado, the first automated meters were deployed by co-ops in the early 1990s. Known as “Turtle” meters, these meters slowly sent meter readings back to headquarters, eliminating the need for meter readers to drive the countryside collecting meter readings.
Those first Turtle meters have since been replaced by more comprehensive AMI meters that provide more information to the co-op and the co-op members. Nationwide, 65 million smart meters had been installed by the end of 2015, with countless household installations since then and more coming soon. In Colorado, Mountain View Electric is among the co-ops currently studying how it can upgrade to AMI meters.
National activity in policy, regulations and technology will continue to change and modernize the electricity grid across the country, and Colorado’s electric cooperatives will continue to keep up-to-date with new technologies that will benefit their members and operations.
Holy Cross Energy “REVs Up Your Ride”
Holy Cross Energy in Glenwood Springs is promoting electric vehicles in the hopes that more of its members will buy the cars and start utilizing electricity to fuel their cars rather than gasoline.
Holy Cross officials joined dignitaries from Garfield, Pitkin and Eagle counties at co-op headquarters recently to announce the launch of the electric vehicle sales event, “REV Up Your Ride,” a campaign to drive up purchases of electric vehicles.
For the sales event, which runs through June 30, four auto dealerships are offering discounts on seven models of electric vehicles, including plug-in electric and gasoline hybrids and plug-in battery electric vehicles. The discounts can be combined with Colorado’s tax credit up to $5,000 and federal tax credit up to $7,500.
Vail town councilwoman Kim Langmaid says, “The EV Sales Event goal is for the dealerships to sell at least 50 electric vehicles to residents and businesses in the three counties.” The sales event also set a goal of increasing public charging stations in the region by 25 percent, growing the current number of stations to 200 by the end of the year.
Compared to other transportation fuels, electricity is the cheapest. In Colorado, the average price of gasoline is currently about $2.32 per gallon, while the price of electricity purchased from Holy Cross Energy is $0.94 per eGallon. EVs also have fewer moving parts and are often much simpler than a conventional vehicle. No oil changes are required, brakes last longer and maintenance costs can be cut in half, according to energy.gov.
“Electric vehicles are shifting the transportation fuel market away from oil and toward electricity energy, a domestic energy source,” Glenwood Springs city councilman, Stephen Bershenyi says. “That supports Colorado electric utilities and their fuel providers,” he continues, “and raises consumer demand for more renewable energy.”
EV Charging Station Up and Running in Co-op Territory
Gunnison County Electric Association and the town of Crested Butte just announced a new electric vehicle (EV) charging station in Crested Butte’s Town Plaza. The charging station represents the first public Level II (240 volt) charging station as well as the first alternative fuel station in Gunnison County.
GCEA secured a Charge Ahead Colorado grant that provided the lion’s share of the station hardware cost. The town of Crested Butte provided the location. GCEA also provided labor and materials to install the station.
Under the terms of the grant, the charging station is currently free of charge. With two connections at the station, EV owners may charge their vehicles up to eight hours. This allows drivers to spend the day experiencing local sights and activities while still ensuring availability of the station to all EV drivers.
The EV charging station can charge all new generation electric and plug-in hybrid electric vehicles, such as the Chevy Volt, Nissan Leaf, Ford Focus Electric and more. The station is easy, reliable and safe to use.
