EVs improve our air quality. Vehicles are one of the two largest sources of air pollution, and a majority of Colorado residents live in areas of the Front Range that violate federal air quality standards. Dirty air is unhealthy for all of us, and it has a particularly negative impact on children, the elderly, and people suffering from asthma or lung disease. Electric vehicles have no emissions from the tailpipe and are so much more efficient than gas cars. A 2017 study for the Regional Air Quality Council found that EVs emit 99 percent less volatile organic compounds and 30 percent less nitrogen oxides than a new gas car today.
EVs bring real economic benefits to consumers. Fuel cost savings can approach $1,000 per year for every electric vehicle. If Colorado is able to achieve the goals set out in the state’s recently adopted EV plan, consumers will save over $500 million per year by 2030. Those consumer dollars will be reinvested in our communities, supporting local businesses and creating jobs…
But the economic benefits don’t just help EV drivers; getting more EVs on the road also will lower everyone’s electric bills. EVs help utilities make more efficient use of their existing power plants and grid infrastructure (which all of us have to pay for), thereby spreading out the costs more and reducing the share that each of us pay.
Here’s how that works. Utilities have to build their power plants for peak electrical use, which normally happens during the day – and all of us pay a portion of that infrastructure cost. But most EV drivers charge at night in preparation for the next morning’s drive, and night is when other electrical demands are low and power plants have excess capacity. So by charging their cars at night, EV drivers help utilities pay down their fixed costs. A study by a national consulting firm found that every EV on the road drives down the total electricity costs paid by other customers by $650 — and by 2030, ratepayers could be saving $70 million per year! The same study found that high levels of EV adoption would lead to total net economic benefits across Colorado of $43 billion by 2050.
Despite all of these benefits, the state Senate recently voted in a party line vote to end the state electric vehicle tax credits (the House rejected this bill). Others have called for new fees on EVs, based on the argument that EV drivers don’t pay gas tax. But EV owners already pay an extra vehicle registration fee, that is designed to pay the same amount into the highway fund as a gasoline vehicle that is as efficient as an EV would pay. It doesn’t make sense to add even more fees at a time when EVs still make up a very small part of the market.
If we want to achieve all the benefits that EVs bring, we need to get a lot more on the road. Because Colorado has supported EVs with a tax credit and state investment in charging stations, the EV market here is one of the best in the country, with the sixth-highest market share of any state in 2017. Sales are growing by over 50 percent per year.
Even though new U.S. wind power installations were down in 2017, wind energy is expected to pass hydro as the nation’s top renewable energy source this year.
A new report underscores that even as Republican leaders remain resistant or even hostile to action on climate change, their states and districts are adopting renewable energy at some of the fastest rates in the country.
Four states—Iowa, Kansas, Oklahoma and South Dakota—now get more than 30 percent of their in-state electricity production from wind, according a new report by the American Wind Energy Association…
While the U.S. wind power industry continued to expand last year, however, its growth rate slowed, with 7 gigawatts of capacity added in 2017, down from more than 8 gigawatts added in 2016.
The slower growth likely was due in part to changes in tax credits. Developers could take full advantage of the federal Renewable Energy Production Tax Credit for wind energy through the end of 2016, but it began phasing down starting in 2017. And the governor of Oklahoma, the state with the second-highest wind power capacity, signed legislation in 2017 to end state tax incentives for the industry three years early amid a budget crisis…
But the total slice of renewables—which provide about 17 percent of the nation’s electricity—is far short of the energy transition experts say is needed to avoid dangerous warming. A paper last year by some of the world’s leading climate change experts said renewables need to make up 30 percent of the global electricity supply by 2020 in order to meet the goals of the Paris climate agreement.
A cooperative that serves four Western states could soon be losing customers amid concerns it’s not moving away from coal quickly enough.
Colorado-based Tri-State Generation & Transmission boasts of having the most solar generation of any G&T in the United States.
But whether it’s shifting to renewables quickly enough from its coal-heavy portfolio — and flexible enough to accommodate locally-generated electricity — has become a central issue with several of the 43 member cooperatives.
Directors of one of those member co-ops, La Plata Electric Association, voted in January to study alternatives during the next 10 to 15 years. The decision was made by the Durango, Colorado-based co-op after a petition was signed by 1,000 people and 100 businesses calling for 100 percent renewables with deeper penetration from local sources.
“We are buying our electricity from one of the dirtiest sources in the United States and paying well above market prices,” says Guinn Unger Jr., a La Plata director who favors a study of the co-op’s alternatives. “Why wouldn’t we want to explore our options?”
Colorado’s Delta-Montrose Electric Association began negotiating a buy-out with Tri-State last year with much the same goal: greater development of local renewable resources.
A template for both Colorado co-ops was established in 2016 when a New Mexico co-op, Taos-based Kit Carson, left Tri-State and signed an all-requirements contract with Guzman Renewable Energy Partners, a wholesale broker. Guzman paid the $37.5 million exit fee to Tri-State. It also promised to work with Kit Carson to develop 35 megawatts of solar arrays in Kit Carson’s three-county service area until 2023, when federal investment tax credit is set to expire. Kit Carson and Guzman are also planning to add battery storage.
Luis Reyes Jr., chief executive of Kit Carson, says consultants to his co-op concluded that ratepayers would save $50 million to $70 million over the life of the 10-year contract. The plan includes rapid construction of local solar farms and robust purchases of wind generation likely combined with battery storage.
Bob Bresnahan, a Kit Carson director and retired executive from Nike, says he believes solar will meet a third of residential electrical demand by 2022. He also contends the co-op can make deep inroads in its goal of 100 percent renewable generation by 2030.
La Plata’s contract commits it to getting 95 percent of its wholesale electricity from Tri-State Generation & Transmission through 2050. This commits La Plata to paying Tri-State 7.3 cents a kilowatt-hour even as wind and solar prices continue to tumble. Elsewhere in Colorado, Xcel Energy has received bids from wind developers at less than 2 cents a kWh and solar plus storage far below what Tri-State is charging La Plata.
Member cooperatives of Tri-State can produce more than 5 percent of their total electrical use, the result of a 2015 ruling by the Federal Energy Regulatory Commission. Still in question are the terms. Tri-State, in an appeal to FERC, wants a ruling that says that member co-ops must pay for what Tri-State calls its fixed costs related to power production. FERC has not ruled on that case, which was filed in early 2016.
‘We’re bullish on renewable energy’
Tri-State’s 43 member cooperatives collectively deliver electricity to 200,000 square miles in New Mexico, Colorado, Nebraska and Wyoming. Their 615,000 metered members/customers include Telluride and other ski areas in Colorado and giant circles of corn on the Great Plains, oil-and-gas fields in New Mexico and some of Denver’s fastest-growing suburbs.
Co-ops created Tri-State in 1952 to deliver electricity from new giant dams being built in the Missouri and Colorado River basins. Hydro still provides about half of Tri-State’s 1,115 megawatts of renewable generation. Wind constitutes the largest share of the new renewables, but the 85 megawatts of contracted solar are tops in the nation among G&Ts. Member renewable projects total 98 megawatts.
“We are bullish on renewable energy,” says Tri-State spokesman Lee Boughey.
In 2005, with demand still rising sharply, Tri-State was bullish on coal. Wanting to build a major new coal-fired power plant in Kansas, it asked member co-ops to extend their all-requirements contracts by a decade, to 2050, the presumed lifespan of the plant. Kit Carson and Delta-Montrose refused.
Finally, in March 2017, Tri-State got permits from Kansas to build the plant but has indicated it will not do so. Instead, it is shedding coal-fired generation. In December, the association lost its 40-megawatt stake in a unit at New Mexico’s San Juan Generating Station. It’ll lose another 100 megawatts of part-time generating capacity at Nucla, Colorado, by 2023 and then 102 additional megawatts of generation at Craig, Colorado, before 2026. All are the result of settlements under the Clean Air Act to reduce regional haze.
Unger, the La Plata board member, says 60 percent of Tri-State’s electrical generation still comes from coal. Tri-State will only confirm 49 percent for 2017, but also reports 19 percent of its electricity comes from contract purchases.
In Durango, La Plata’s subcommittee has met several times, but Unger says it’s still not clear to him that La Plata should, like Kit Carson, leave Tri-State. He’s disturbed that nearly half the board members didn’t want to evaluate the co-op’s options.
“We should be asking ourselves, what are the facts?” he says. “People are not willing to look at it.”
Unger is also annoyed by implications that Kit Carson was forced to increase rates after it left Tri-State to pay the exit fee. “News articles indicate that the rate increase was to help the co-op with unprofitable affiliates, but the timing is a concern,” wrote Mike Dreyspring, chief executive of La Plata Electric, in an op-ed published in the Durango Herald.
Kit Carson’s rates, responded CEO Reyes, “have not increased one cent due to the buyout.”
‘Coal is no longer the lowest cost fuel’
Directors of Delta-Montrose were unanimous in January 2017 in approving exit negotiations. Neither DMEA representatives nor Tri-State will comment on the talks, citing a non-disclosure contract.
“What our board members want most is the flexibility to be able to diversify generation resources,” says Jim Heneghan, DMEA’s renewable energy engineer. Directors, he says, see local renewable generation as a vehicle for economic development.
Delta-Montrose began pursuing this vision of local generation about a decade ago. it’s in a region of organic apple farms and other agriculture production along with one remaining coal mine. Scores of high-paying coal mining jobs have been shed and the region still lags the economic vigor found in more urban areas.
A diversion project east of Montrose completed in 1909 contains a major fall before delivering water to farms. In harnessing that falling water to produce electricity, Delta-Montrose hit Tri-State’s 5 percent cap on local generation. When an outside developer proposed a third hydro plant to Delta-Montrose, the co-op took the proposal to FERC. In 2015, FERC agreed that the co-op was required, under the Public Utility Regulatory Act of 1978, to negotiate purchase of power generated by what PURPA calls a qualifying facility.
Tri-State concedes that it cannot interfere with a member’s purchase of energy from a qualifying facility. But it wants to be able to assess the co-ops for the fixed-cost portion of sales it has lost above the 5 percent threshold.
“It’s a question of how members relate to each other within their association,” explains Tri-State spokesman Boughey. “Each association member agreed to equitably share costs, and that if members self-supply in excess of the 5 percent provision they would not be paying their fair share of the association’s fixed costs. These costs would have to be made up by other members.”
In Durango, Mark Pearson sees a different equity issue. The director of the San Juan Citizens Alliance, an advocacy group, he says the tens of millions of dollars exported from the local economy to Craig and other coal-mining towns would be better kept at home. Of La Plata’s revenues, 67 percent goes to Tri-State for electrical production elsewhere.
“This is great for Craig to have this money raining down on their community, but we should have that money circulating in our community. If we can keep the money local, it’s better economically for us,” he says.
Taking the long view, DMEA director John Gavan sees community choice aggregation coming, where consumers will have the choice of many power suppliers.
Unlike electrical generation even today, he foresees changes driven from the grassroots that pose questions about Tri-State’s one-member, one-vote setup. He contends smaller co-ops have been more easily influenced by the expertise of Tri-State’s coal-minded officials. “Tri-State is a Senate without a House of Representatives,” he says.
Both Pearson and Gavan see resistance to change being the fundamental issue. “It’s just hard for the old guard to change as quickly as the world is changing, to realize that coal is no longer the lowest cost fuel,” says Pearson.

Prices for solar, wind, and battery storage are dropping so rapidly that renewables are increasingly squeezing out all forms of fossil fuel power, including natural gas.
The cost of new solar plants dropped 20 percent over the past 12 months, while onshore wind prices dropped 12 percent, according to the latest Bloomberg New Energy Finance (BNEF) report. Since 2010, the prices for lithium-ion batteries — crucial to energy storage — have plummeted a stunning 79 percent.
“The economic case for building new coal and gas capacity is crumbling,” as BNEF’s chief of energy economics, Elena Giannakopoulou, told Bloomberg.
At the same time, solar and wind plants — which are increasingly being built with battery storage — are eating into the utilization of existing coal and gas plants, making them far less profitable. For instance, the super-efficient combined-cycle gas turbine (CCGT) plants that have been popular in recent decades, were designed to be used at full power between 60 percent and 90 percent of the time.
But their actual utilization rate (also called the “capacity factor”) has been plummeting in recent years, and is now close to a mere 20 percent in countries as diverse as China, Germany, and India.
FromThe Conversation US (Eric Hittinger/Eric Williams):
The market for energy storage on the power grid is growing at a rapid clip, driven by declining prices and supportive government policies.
Based on our research on the operation and costs of electricity grids, especially the benefits of new technologies, we are confident energy storage could transform the way American homeowners, businesses and utilities produce and use power.
Energy storage in this context simply means saving electricity for later use. It’s like having a bunch of rechargeable batteries, but much larger than the ones in your cellphone and probably connected to the grid.
After annual average growth of about 50 percent for five years, the U.S. electricity industry installed a total of 1 gigawatt-hour of new storage capacity between 2013 and 2017, according to the firm GTM Research. That’s enough to power 16 million laptops for several hours. While this amount of storage is less than 0.2 percent of the average amount of electricity the U.S. consumes, analysts predict that installations will double between 2017 and 2018 and then keep expanding rapidly in the U.S. and around the world.
To see why this trend is a big deal, consider how electricity works.
It takes a hidden world of complexity and a series of delicate balancing acts to power homes and workplaces because the grid has historically had little storage capacity. After being generated at power plants, electricity usually travels down power lines at the speed of light and most of it is consumed immediately.
Without the means to store electricity, utilities have to produce just enough to meet demand around the clock, including peak hours.
That makes electricity different from most industries. Just imagine what would happen if automakers had to do this. The moment you bought a car, a worker would have to drive it out the factory gate. Assembly lines would constantly speed up and slow down based on consumer whims.
It sounds maddening and ridiculous, right? But electric grid operators basically pull this off, balancing supply and demand every few seconds by turning power plants on and off.
That’s why a storage boom would make a big difference. Storage creates the equivalent of a warehouse to stow electricity when it is plentiful for other times when it is needed.
FromColorado Politics (Marianne Goodland) via The Durango Herald:
Hickenlooper, speaking to an audience at the 27th annual Governor’s Forum on Agriculture this week, said that the Colorado Outdoor Recreation Industry Office met with representatives from recreation offices and outdoor recreation companies from eight states, and the result was something called the Colorado Accord. It’s a nonpartisan effort to work on issues related to clean air, water and public land – areas the trade association strongly supports and part of the reason the trade show moved to Colorado, he said.
This accord is the start of an opportunity for Colorado to be a national leader in outdoor recreation, Hickenlooper said. The companies involved are small – around 10 to 15 employees.
“They don’t want to live in the cities or their businesses to be in the cities,” he said. “These are companies that are naturals for smaller communities … . This is a chance to build a relationship between farms and ranches and outdoor recreation. If you want more jobs in your towns, there will never be a better chance.”
The governor also addressed the ongoing negotiations over the North American Free Trade Agreement, and the importance of maintaining partnerships with Canada and Mexico, which are NAFTA partners. The renegotiation of the 22-year old agreement hasn’t gone as quickly as he would like, Hickenlooper said.
“Our relationships with Canada and Mexico need to remain strong,” given that more than half of Colorado agricultural exports go to those two countries, he said, adding that NAFTA has the potential to do so many good things for Colorado, and that he has talked with officials from both countries.
“They just want a deal,” Hickenlooper said.
Hickenlooper said he recently spoke with the U.S. Secretary of Agriculture Sonny Perdue and their positions align on several issues, such as the need for better and faster negotiations with South Korea, China and India on agricultural trade; about volatility in the labor market for ag, and for a more balanced approach on agricultural regulations.
One of the state’s highest priorities for global exports, he said, is to open up Asia. “There’s an insatiable appetite for beef and pork” in South Korea, China and Japan, and the U.S. needs a fair deal with those countries.
Hickenlooper also made a push for a long-term funding solution for the Colorado water plan. Last month, the governor said he favored a change in how the state collects severance taxes on oil and gas, saying, among other things, that Colorado has the lowest severance taxes on oil and gas in the region.
A court case two years ago with oil giant BP dramatically reduced the amount of severance taxes the state can collect, which has been used in the past to mitigate oil and gas activities in rural communities and to pay for water projects around the state. The state had to take money out of its general fund to pay for the property tax deductions the court decided BP was owed. After that, the state’s share of severance taxes dropped from around $150 to $200 million per year in 2016 to about $25 million last year, Hickenlooper said.
Without a structural change in how severance taxes are levied, he warned, severance taxes could come to an end. “But let’s get a referred measure on the ballot” that will provide a fair tax structure for oil and gas, he said. “It’s a social contract with the state of Colorado. If it were presented properly,” voters would not walk away from it.
That didn’t fly with Senate President Pro tem Jerry Sonnenberg of Sterling, who was in the audience and is president of the board of the Colorado Agricultural Leadership Program, which hosts the annual agriculture forum. Sonnenberg disputed the governor’s claim that Colorado has the lowest severance taxes in the region.
Sonnenberg told Colorado Politics that “we have robbed $400 million from severance taxes” to cover budget shortfalls, including $100 million to pay BP for the lawsuit. “We need to figure out how not to rob Peter to pay Paul,” Sonnenberg added. “If we truly want to do something about severance tax, maybe we add all energy: wind, solar, nuclear and hydroelectric.”
Solar farms, wind turbines and hydroelectric dams are getting close to surpassing nuclear power plants contribution to the U.S. electrical grid, according to a new report by Bloomberg New Energy Finance.
Last year 18 percent of electrical generation came from renewable energy sources – more than double what they did a decade ago – the report said. Nuclear power plants represent 19.7 percent of the generation on the grid, according to the U.S. Department of Energy, surpassed only by coal and natural gas plants.
“The massive and historic transformation of the U.S. energy sector clicked into a higher gear in 2017, despite some new headwinds including policy uncertainties,” the report entitled “Sustainable Energy in America: 2018 Factbook” read. “Renewable deployment grew at a near- record pace.”
The growth comes even as the Trump administration has curtailed or eliminated restrictions on greenhouse gas restrictions while also trying to expand fossil-fuel production in the United States.
But so far it has done little to turn investors away from renewable energy, which is widely seen as an area of growth in the decades to come as countries try to limit the damage of climate change.
Investment in wind, solar and other renewable technologies totaled $333 billion in 2017, the second highest level on record, according to the Bloomberg report.
The impact on the atmosphere can already be seen. The expansion of renewables, as well as the shift away from coal to natural gas, has sent the nation’s greenhouse gas emissions to their lowest level since 1991, according to Bloomberg.
