Cool Technologies Keep Lineworkers Well-Connected

By Tom Tate
When electric cooperatives were formed in the 1930s, their technology was primitive by any standard — digging holes for the utility poles by hand, walking the poles up into those holes, using ladders to reach equipment needing service. And if you had to get in touch with the line crew, face-to-face communication was the only option.

Today, the lineworker rivals any other worker when it comes to having the necessary tech to get the job done safely, quickly and more accurately. Let’s take a look at a few of the devices behind this evolution, starting with the tablet.

Many electric co-ops send their crews into the field with ruggedized tablets. What are those? They are tablets (and smartphones) with special cases and screen protectors built to tough specifications that will allow a lineworker’s devices to survive bouncing along in a line truck, being exposed to all kinds of weather and being dropped into a bucket or toolbox.

Depending on the electric co-op, the data and other content on these ruggedized devices varies. Often work orders detailing the day’s project are found on these devices. These can include construction drawings for how the job is to be built, the bill of materials so the crew knows what to pull from inventory before hitting the road, and system maps so lineworkers know exactly where to go. Gone are the reams of paper and cumbersome map books of the past.

Not quite as new, but equally important, are global positioning system, or GPS, coordinates. This functionality might be built into the lineworker’s tablet, a ruggedized smartphone or a handheld unit. As more co-ops map their systems using GPS coordinates, the GPS capability gets the crews where they need to be in an efficient manner. Some GPS units are designed specifically for heavy trucks, and plot routes that avoid bridges with weight limits or roads with height restrictions.

Close up of an infrared camera

Infrared cameras help lineworkers scan power lines and other equipment and find hot spots that could mean equipment that could fail.

Another popular tool is the forward-looking infrared camera, also known as FLIR. Many people are familiar with this technology from the many ghost hunter programs currently on television. With a FLIR camera, crews can rapidly scan power lines, transformers and other equipment when searching for hot spots. A piece of distribution equipment about to fail will often get hot. While not visible to the naked eye, it shows up clearly on a FLIR display. Scanning the system with a FLIR camera is a fast and accurate means of spotting a problem before it becomes an outage.

And today, many lineworkers have eyes in the sky in the form of drones. Colorado’s electric cooperatives cover territory that is often difficult to access when they need to survey the system for necessary repairs or to locate a new power line route. Instead of tackling the job on foot or on four-wheelers, the co-op crews might be able to send in a drone. Flying above the area provides a great view of the situation and allows the crew to make an assessment of what to do next without having to be there in person. This is especially useful after a major storm when roads can still be blocked.

Cooperatives are laser focused on providing the best reliability possible at the lowest possible price. A major aspect of reliability is getting the lights back on as quickly as is safely possible after an outage. Key in this is the outage management system, or OMS. This system builds on “geo-tagged” system maps (each pole has its GPS location mapped), sophisticated engineering models of the distribution system and, for maximum accuracy, an advanced metering system.

When an outage occurs, the system uses models and databases to determine the exact location of the fault and the extent of the outage. Crews can then be sent to the right spot to correct the problem. Part of this restoration effort might be a vehicle tracking system that tells operations staff the exact location of each line truck. The crews closest to the outage are sent to restore power — and essential information can be accessed on the tablets, depending upon the situation.

Sometimes all the technology in the world is not enough and a good old-fashioned visual inspection is required. During daylight hours, it can be easier to see the cause of a problem. But at night, lineworkers need a reliable source of light. Today, that comes from LED flashlights and truck-mounted lights. These powerhouses are a fraction of the size of regular flashlights, and they make an older incandescent model look like a candle by comparison. In the hands of a lineman, they provide an amazing view of the lines during the darkest of nights.

Technology is permeating every aspect of cooperative operations, allowing your electric co-op to constantly improve your service. The well-connected lineworker is at the forefront of that technical evolution.

Tri-State Committed to Reduce Statewide Emissions

During recent proceedings, the Colorado Air Quality Control Commission accepted Tri-State Generation and Transmission’s voluntarily-announced retirement dates for its coal power plants Craig Station Units 2 and 3. This is after the AQCC was considering enforcing early closures.

According to a Tri-State press release, the plan meets or exceeds federal requirements to improve visibility in Colorado’s national parks and wilderness areas, according to Tri-State CEO Duane Highley. The cooperative power supplier’s Craig Station Unit 1 will retire by December 31, 2025; Craig Station Unit 2 by September 30, 2028; and Craig Station Unit 3 by December 31, 2029.

And separate from the AQCC proceedings, Tri-State and Gov. Jared Polis announced Tri-State’s goal to reduce greenhouse gas emissions in Colorado by 80% by 2030. This is part of Tri-State’s innovative Responsible Energy Plan. Tri-State filed its Electric Resource Plan with the Colorado Public Utilities Commission on December 1. The ERP includes a preferred scenario to reach emissions reductions by retiring Craig station, adding 1,850 megawatts of renewable resources and a significant reduction in greenhouse gas emissions that support state goals.

EV Charger Added, Thanks to Co-op

The town of Fraser took advantage of Mountain Parks Electric’s Electrify Everything program and installed a Level 3 electric vehicle charger. With a grant from the Granby-based electric cooperative and the Colorado Energy Office, this is the first fast-charging station in Grand County. It is located at Lions Ponds, and the ribbon-cutting ceremony was held in late November.

Co-op Commits to Go Carbon Free

Holy Cross Energy in Glenwood Springs announced a new, ambitious 100X30 goal to provide 100% carbon-free electricity to its consumer-members by 2030. The announcement was made in a press conference December 14 with Gov. Jared Polis offering his congratulations to the co-op. The 100X30 plan follows the co-op’s Seventy70Thirty plan announced in 2018 in which the co-op pledged to provide 70% of its power from clean and renewable resources and reduce greenhouse gas emissions by 70% from 2014 levels by 2030. That plan is ahead of schedule and the co-op rewrote its goal to create the 100×30 goal.

Helping Hands from Outage Restoration Teams

By Mona Neeley, CCL Editor

Being part of a large network is never more important than when a natural disaster hits an electric cooperative. Take, for example, when the monstrous and destructive East Troublesome Fire swept through Grand County and Mountain Parks Electric’s service territory in October. The 60 employees of the area’s local electric cooperative were not on their own.

MPE is a small, local, independent organization that serves Grand and Jackson counties as well as parts of Larimer, Routt and Summit counties in the central mountains of Colorado. But the co-op is not totally on its own when disaster strikes. It is part of a network of electric co-ops that all adhere to the sixth cooperative principle: cooperation among cooperatives.

With a call to the Colorado Rural Electric Association, the electric co-ops’ statewide trade association, the word was out that MPE needed assistance. Just a couple days later utility trucks from electric co-ops across the state rolled in to Granby. Crews of lineworkers were there to assist MPE in getting the backbone of its system back on line so that the local crews and hired contractors could then methodically replace and repair individual services and infrastructure.

Crews from neighboring electric co-ops assist in getting power lines restored after a summer storm on the eastern plains.

The same thing happened back in June when the derecho made meteorological news as it ripped across Colorado with its thunderstorms and extreme wind gusts. Tens of thousands of Colorado electric co-op consumer-members were without power in territories served by Highline Electric Association in Holyoke, K.C. Electric Association in Hugo, Morgan County Rural Electric Association in Fort Morgan, Poudre Valley Rural Electric Association in Fort Collins, Southeast Colorado Power Association in Lamar, United Power in Brighton, Y-W Electric Association in Akron and Yampa Valley Electric Association in Steamboat Springs.

But as soon as the windstorm was over, electric co-ops across Colorado and western Nebraska that had not been affected by the storm stepped up to assist in safely getting the lights back on for these co-ops. Neighboring co-ops that could spare a crew, sent it to help. Contractors, who supplement co-op crews on projects throughout the year, made their crews available.

That quick response from other co-ops comes from a combination of a centuries-old co-op tradition and agreements among electric cooperatives.

Lineworkers prepare to get the poles and lines back up in a neighborhood affected by the East Troublesome Fire.

This help is needed, especially by smaller co-ops, because these large natural disasters (such as wildfires, derechos, ice storms, blizzards and tornadoes) that cause devastation is more than many local electric co-ops can quickly repair on their own. When multiple areas in a co-op’s service territory are without electricity and there are only four or five crews available to restore the system, electric co-ops depend on other co-ops in their state and national network for assistance.

The residents of Grand County saw crews from Highline Electric, Gunnison County Electric Association in Gunnison, Southeast Colorado Power Association, United Power and White River Electric Association in Meeker arrive October 26. They came from all corners of the state as part of a plan called a “mutual aid agreement.” And San Miguel Power Association in Nucla arrived a couple days later, once it was determined that more help was needed.

“It is a natural extension of who we are,” says Kent Singer, executive director of CREA. “Helping each other is something we do naturally as part of our co-op family and our culture.”

An agreement is one thing, but success means carrying it out effectively. To that end, electric co-ops rely on planning and shared experiences, says Dale Kishbaugh, CREA director of safety and loss control. Colorado’s electric co-ops spend time planning for disasters, talking through the what-ifs of problems and sharing experiences with each other as they meet regularly to keep procedures updated.

The response to the East Troublesome Fire came together relatively quickly after that fire took a turn and developed a speed no one expected. Once it burned through the system and MPE knew where it lost its lines, the response was quick but planned, with the idea that when mutual aid crews arrived the work could begin and materials would be available.

With other natural disasters, even with other wildfires, that planning can often start before the disaster actually strikes. For example, weather predictions can give a co-op notice of a possible blizzard or ice storm. Then materials can be readied and preliminary assistance can be arranged.

Another example is the Cameron Peak Fire, the largest fire in Colorado history, which ignited in August and was still only 92% contained at magazine deadline. While dangerous and, at times, unpredictable, it burned at a slower pace than the East Troublesome Fire. This gave Poudre Valley REA crews opportunities to prepare for where the fire might burn through its system.

Before the fire arrived, PVREA lineworkers wrapped poles in high-risk areas with fire protection materials. They met regularly with incident command to determine where the electric system might be affected and where the co-op might need to de-energize lines. Once the fire burned through an area and it was deemed safe to enter that area, PVREA crews and contractors got right to work replacing burned poles and restringing power lines. They were prepared and, this time, PVREA did not have to rely on the mutual aid agreement. But that agreement was there and could be used if needed.

No electric co-op has to go it alone. Each independent, local co-op is part of the electric co-op family, part of a statewide and nationwide network of electric co-ops, all ready to lend a hand to get the lights back on safely wherever they go out.

Co-ops Back High-Speed Internet for Mancos

Families are still facing the challenges of remote learning, but the town of Mancos is helping to reduce some of the burden for people who don’t have reliable internet access.

It was found that 20% of families in the Mancos school district were without reliable internet access at home. So the town of Mancos teamed up with FastTrack Communications to deliver free, high-speed internet from 6 a.m. to 10 p.m. daily at a local park. FastTrack will provide a 100 mpbs dedicated internet connection available to families and students who otherwise won’t have a connection to participate in remote learning.

FastTrack is an internet subsidiary of southwestern Colorado electric cooperatives La Plata Electric of Durango and Empire Electric Association of Cortez.

San Isabel Electric Launches Efficiency Program

This fall, Pueblo West-based electric cooperative San Isabel Electric rolled out its Empower program. This expansion of its energy-efficiency programs helps people create an energy-efficient home or business space with free energy assessments, net-metered home solar power systems, electric vehicle and charger rebates for consumer-members and products such as high-velocity, low-speed fans, electric water heaters, electric thermal storage and air source heat pumps, just to name a few. Many of these products and services can be bundled to maximize efficiency and energy savings.

According to an October press release, the San Isabel Electric Board of Directors said Empower is essential to continue the path of providing value for not only SIEA consumer-members but the entire southern Colorado region.

YVEA Receives Grant to Expand Fiber Infrastructure

In late October, Steamboat Springs-based Yampa Valley Electric announced that the U.S. Department of Agriculture will award $6 million to YVEA and its fiber subsidiary, Luminate Broadband, to expand fiber internet service in northwestern Colorado.

The USDA will provide funding to YVEA/Luminate through its ReConnect program to deploy a fiber-to-the-premises network. This will connect 264 rural households, 27 farms and ranches, 27 businesses, and three post offices to high-speed internet. With this funding, YVEA/Luminate will construct 200 miles of middle mile fiber to connect northwest Coloradans in Routt, Moffat and Eagle counties.

Innovations in Heat Pumps

By Amy Higgins

Colorado’s electric cooperatives have a reputation of staying on top of innovation and energy efficiency, and while heat pumps aren’t new to the beneficial electricity market, their advancements are.

Cold-climate, air source heat pump (ccASHP) is one of the latest innovations in beneficial electrification. These products can reduce air pollution and energy costs by switching from direct fossil fuels, like propane or natural gas, to electric resources that emit less carbon emissions.

“Overall, [ccASHPs] emit less carbon per unit of heat than burning fossil fuels,” explains Tri-State Generation and Transmission Relationship Manager Peter Rusin. “As [Tri-State] implements its Responsible Energy Plan, over the next four years and over the next 10, that gap is only going to grow compared to propane and natural gas — that’s going to be much better for the environment.”

Unlike the heat pumps of years past, today’s heat pumps include variable speed, or inverter, technology that allows them to operate over a wider range of temperatures. “So, instead of going down to 40 or 35 degrees where that heat pump is working before you need a backup, now we’re seeing systems get down to negative 13, negative 20,” Rusin explains. He says this variable speed technology can either eliminate or reduce the need for a backup because of the unit’s ability to carry temperatures much deeper into the extremely cold range, meaning it’s possible that it can be used as a primary heat source.

Granby-based Mountain Parks Electric, the National Rural Electric Cooperative Association and Xergy Consulting recently conducted a pilot study of three homes in the Fraser area in which the homes were outfitted with ccASHPs. The study showed that one 2-ton ccASHP unit reduced total annual heating costs by approximately 30%. (Visit mpei.com/pilot-programs to read the complete findings.)

These ccASHPs are not only friendlier to the environment, but they are also more cost effective than a propane furnace or resistance baseboard system and safer to operate seeing as you’re essentially eliminating ignitable vapors in your home. “Any time you burn a fossil fuel, you can create carbon monoxide, carbon dioxide, hydrocarbons — all these things that really impact your indoor air quality,” says Mike Frailey, relationship manager at Tri-State. “Switching to an air source heat pump eliminates that [emission] from your propane or natural gas furnace. There’s a reduction in the CO2 emissions from an exhaust standpoint, too, such as a chimney.”

Frailey and Rusin share that they’re also seeing commercial interest in ccASHPs. For example, they’re working with a school in Wyoming that is interested in adding 55-tons of heat pump technology to replace a steam boiler system, and state rebates and educated resources could help them cut costs. Frailey adds, “In that specific application, it’s going to be a mix of split systems for some smaller rooms and then they’re doing three 8½-ton packaged rooftop units, so there are commercial applications and it seems it’s going to continue to evolve and grow.”

However, the upfront cost of a few grand or more might be a drawback for some. To relieve Colorado’s electric cooperative consumer-members of the cost burden, Tri-State offers a $450 rebate per ton for a new ccASHP and some of Colorado’s electric cooperatives offer rebates of their own. MPE, for example, offers a rebate of $500 per ton, which could mean $3,000 or more off the consumer’s bottom line when combined with Tri-State’s rebate.

Several Colorado towns are some of the coldest in the nation during the winter, but innovation in the energy sector and a commitment to provide electric co-op consumer-members the safest, most reliable service at the lowest cost possible is at the forefront of every co-op in the state. Products such as ccASHPs can keep Coloradans safe and comfortable during some of the coldest times.

To learn more about ccASHPs, contact your local cooperative. They can assist you in finding knowledgeable contractors to get the job done correctly, rebates to help your bottom line and information on how to stay comfortable in the dead of winter — they are the trusted resources.
