Few EVs in rural Colorado now, but with spark that may change

Expect to see fast-charging stations along highways in 2018

GUNNISON, Colo. – Crested Butte and Gunnison together may have 22 electric vehicles, not counting plug-in hybrids or EVs driven into the mountain valley from elsewhere.

Charging stations? That’s easy. Five can be found between in the two towns and another one is located 55 miles away at Lake City, in Hinsdale County.

None of the charging stations get a ton of use, but that’s not the point. The purpose of the free fueling stations is to get people comfortable with the idea of electric cars.

Colorado’s state government has been assisting in many local efforts to smooth and accelerate the transition to electrified transportation. Gov. John Hickenlooper—who is scheduled to make an announcement Wednesday morning at Denver’s Alliance Center about “Colorado’s Electric Vehicle Corridor”—unveiled a plan in 2016 to create electrified interstate highways in common with Utah and Nevada. Last year, other Western states agreed to join in.

Now, the state is expanding its effort to secondary highways, both federal and state.

In doing this Colorado will draw on its share of the Volkswagen settlement. Hickenlooper’s staff has apportioned $10.8 million from the state’s $68 million share to boost installation of charging infrastructure for EVs.

One-third is to be used for in-town locations but two-thirds is to go to highways. U.S. Highway 50 through Gunnison could be a potential recipient.

“If you want to accelerate the adoption of electric vehicles, you want to create a statewide network that allows the owner of an EV to go anywhere in the state,” explains Christian Williss, director of the transportation fuels & technology department at the Colorado Energy Office.

Williss says his department is creating an invitation for proposals to be made by late March. The state hopes to find partners, including rural electrical co-operatives, development corporations, and local and regional governments. The state sees need for charging stations every 30 to 50 miles, more or less, and with fast-charging stations, unlike the cheaper and slower Level II charging stations such as in Gunnison and Crested Butte.

Denver recently commissioned a study that estimated costs of two fast-charging stations and one Level II station, including installation, at $190,000 to $200,000.

While technology is rapidly changing, most cars can get an 80 percent charge at a fast-charging station in 20 to 30 minutes. But it depends upon the size of the battery.

In early December, the Colorado Public Utilities Commission heard testimony about such things as where public money is best spent in charging stations and other elements of public policy. Basalt-based Rocky Mountain Institute was given the most prominent spot of the day, followed by the Southwest Energy Efficiency Project.

Gunnison might not seem like a likely candidate for being at the front end of electric vehicles. It used to have a reputation for deep cold, and it’s still four hours from Denver. It has rich people shuttle in and out, but it’s not an Aspen or Vail. What it does have is a loaner EV called Spark-e that was purchased in 2016 by the Gunnison County Electric Association. It can be borrowed for up to a week to help people decide whether they want to buy an EV of their own. “People are enjoying driving Spark-e so much that it hasn’t been back to the office since June,” reported the association’s December newsletter.

This activity has put Mike McBride, the general manager of the electrical co-op, on the speaking circuit at state-wide conferences. McBride believes Gunnison is at the front edge of efforts to anticipate vehicle electrification in rural areas.

But people in both cities and rural areas, he says, use fundamentally the same criterion when purchasing a car: “Most people base their purchase decisions on a few trips, not their daily us. If you live in Denver but enjoy going to the mountains, you’re going to base your purchase decisions on whether you can still go to the mountains. If you are living in a rural community, you are going to base your purchase on those few occasions when you got to the city.”

From Crested Butte to Denver is 4.5 hours in good weather. Importantly, there are no charging stations along Highway 50 between Gunnison and Salida, 65 miles away. This may matter less as newer models arrive with longer range and lower prices. Changes are rapidly occurring in both dimensions.

Rutt Bridges, a Denver-based author now working on his second book about the future of transportation, points out that Chevy Bolts have a range of 238 miles, while Tesla’s Model 3 has an EPA-listed range of 220 miles. The Bolt costs $37,500 but has been discounted by as much as $5,000, while the Tesla lists for $35,000. Colorado has an additional $5,000 in tax incentives for those with incomes high enough to take advantage of them.

Battery costs have rapidly declined, from $700 a kilowatt-hour seven years ago to $139 now. Tesla and General Motors predict prices tumbling below $100 by 2020, Bridges reported in November in Maize: Techo Food for Thought.

Bridges also believes fueling costs make a strong case for conversion to electric vehicles. Cost of electricity is one-third that of gasoline and has been far more stable, he says. He also cites the greater efficiency of electric motors (90 percent vs. the 20 percent of an internal combustion engine).

Because of these gains and advantages, Bridges projects that sales of EVs will significantly expand beyond the current 1 percent of U.S. vehicle sales. Will Toor, transportation program manager for the Southwest Energy Efficiency Project, points out that Colorado has the 6th largest market share of EVs in the country.

Electrical utilities, with flat and sometimes declining sales in recent years, also have a strong reason to want to see more EVs. This is more straight-forward with investor-owned utilities like Xcel Energy than with electrical co-ops like Gunnison Electric. McBride says environmental goals rank high among many members of his co-op. In co-ops, members are also customers. “We tend to do our best to meet and balance the needs and wishes of our members,” he says.

Environmental goals are high on the list of many co-op members. As aging coal plants have closed, transportation has moved ahead of power supply as the single largest cause for greenhouse gas emissions in the United States.

EVs achieve pollution reduction if electricity comes from less carbon-intensive sources. The power from Tri-State Generation & Transmission, the wholesale provider for Gunnison, remains heavy in coal and, to a lesser extent, natural gas. But it has coal plants going down, too.

As utilities convert to renewable energy, EV charging can be paired with cheap renewables, provided owners are content to let their cars get fueled when the wind is blowing or the sun is shining. Time-of-use rates can encourage this pairing.

Gunnison County Electric has no rates designed with EV charging in mind, but “that may evolve over time” along with other rates, says McBride.

With the proper price signals, charging of EVs can be matched with availability of low-priced power, to the benefit of both the utility and consumers.

Optional time-of-use rates currently are 8.8 cents a kilowatt-hour 19 hours a day and all of Sunday, but 23.2 cents per kilowatt-hour between 5 and 10 p.m. Monday through Saturday. There’s a $35 monthly fee. The default rate 24.7.365 rate is 12.7 cents.

    And the kids are going to sit quietly with their hands folded, eating celery sticks, while the car is charging. The bill for what the family buys, lattes, junk et al while you wait will make gas look like a bargain. nice fantasy

    Let’s talk about winter driving in an EV:
    -EV’s do NOT produce the waste heat of a gasoline vehicle, which is used to heat the cabin. An EV must use battery capacity to heat the cabin, so effective range will diminish in cold weather.
    -Batteries are less efficient when they are cold. In fact, EV’s have battery heating systems to maintain efficiency. Guess where the power for the battery heater comes from?
    -“Heating the cabin and battery combined can increase the auxiliary power load on an EV like the Nissan Leaf from below 1kW to almost 3kW as the temperature goes from 68 F. to 10 F.” (Union of Concerned Scientists). This same article characterizes the decrease in range as “significant”, while trying to convince people that they really don’t need to drive very far.
    Here’s the deal: I’m ready for an electric vehicle:
    -for me it’s a forty mile round trip to town.
    -I need to carry tools to work, groceries, etc.
    -I need high clearance, and I need to go off-road.
    -I need torque, real torque, to deal with deep snow, loads, and steep grades.
    -I need something that works in cold, real cold. Not “below freezing” cold. REAL cold, that effectively goes on for months.
    -I DON’T want to be told to move to town and get a job working for some non-profit for peanuts so I can shoehorn myself into one of those things with nothing but a laptop. I’ll keep travelling with a table saw, thank you.
    -Don’t tell me I have to sit at a charging station for half an hour. Unlike some people, I don’t get paid if I’m not working.
    -I can buy a Jeep Cherokee or old F-150 for $2-3K, and keep it running for another 100K. And you want me to spend $40-70K on a vehicle that I can’t be sure will get me home, and can’t carry me, my wife and a week’s groceries at the same time? Please give me a break.
