Free Energy Resources for Colorado’s Rural Schools

/in /by

Outdated lighting, heating and cooling can cost rural schools, on average, 30 percent more on their energy bills, according to a recent study by the U.S. Environmental Protection Agency. To combat this problem, the Colorado Energy Office’s Energy Savings for Schools program is under way and able to support up to 12 more schools this year.

“The ESS program builds off many years of the CEO’s programmatic work in the K-12 area,” Michael Turner, CEO’s energy efficiency programs manager, explains. Schools across Colorado saved energy and money through a variety of offerings, and now they are part of this program to bring all available resources to bear on those schools with the greatest needs.” It’s a great opportunity for schools looking to improve their learning environment through more efficient operations.”

Through the program, schools receive:
• On-site energy and water audits from an energy engineer
• Evaluation of renewable energy opportunities
• Technical support and energy coaching
• Implementation support and help identifying existing funding and financing options for completing projects
• Recognition for a school’s efforts and opportunities to engage students
• Connections with peer schools and a platform for sharing ideas and knowledge

When a new school joins the program, the ESS team works with the school to collect and review building utility data (electricity, natural gas and water) before the site visit. “Reviewing utility data before a site visit gives us insight into how a building is performing and highlights potential areas of concern,” ESS energy efficiency engineer John Butler says. “Concerns expressed by school staff are used along with insights gained from the historic utility data to help focus the site visit and assessment on problem areas and to customize our approach for each unique facility.”

After the site visit, the energy engineer prepares a customized report with recommendations for the school. “We understand how limited resources — especially staff and financial resources — can be for these rural schools, so we prepare our reports with the aim to help each school prioritize strategies and next steps,” Butler says. “And the report is only the first step. We work closely with school staff to identify what projects make the most sense and help navigate the process of getting projects done. Many times, this means helping schools identify funding or soliciting and reviewing bids from contractors.”

To help fund recommended projects, ESS staff identify other applicable CEO programs, local utility rebates and other state and local programs for schools to leverage. “There are no direct monetary costs for a school to participate in the ESS program. The only costs are associated with staff time to interact with the ESS team and any costs to implement after all external funding sources have been exhausted,” Turner says. “The ESS program supports, and, in turn, is supported by a number of CEO and other related programs, including the Renewable Energy and Energy Efficiency for Schools loan program, Supplemental Environmental Projects, High Performing School Program, Energy Performance Contracting and the Renew Our Schools Program.”

To date, 23 schools received their energy reports and began implementing projects. The graphic to the left outlines the collective potential savings identified for these schools.

Legacy Academy, a tuition free, K-8 charter school in Elizabeth, is one of these schools. “As an administrator who is not an expert in energy savings projects, it was incredibly valuable to have the support from this team when receiving project bids,” explains Legacy Academy’s principal Kurt Naber. “The comprehensive energy audit, combined with guidance and input from the ESS team, helped me to feel confident and well-informed when presenting options to Legacy’s board of directors.”

Legacy Academy is poised to save $13,420 annually as a result of lighting upgrades, ceiling fans and water fixture upgrades installed this year.

“We have been pleased and impressed with the knowledge and assistance that the ESS program has brought to our school,” Naber says. “The representatives from ESS have been a great resource for us as we have evaluated bids and moved forward with several energy-saving projects. Their input gave us assurance that we are making well-informed decisions.”

In addition, with support from the ESS program, Legacy Academy applied for and was awarded Energy Star building certification in November as a result of its efforts to improve efficiency. Energy Star certified buildings outperform 75 percent of similar facilities across the country.

Don’t let your local school miss out on ESS resources to optimize energy performance and save money. CEO is actively recruiting schools from Colorado’s rural and low-income areas to participate in the program’s second year.

MCREA Member Services Representative Bill Annan conducts the energy audit by performing a walk-through of the home or business to collect information. An infrared camera may be used to assist in identifying building envelope weaknesses. Annan also reviews the member’s history of electric consumption and discusses the member’s concerns and goals of energy consumption. Once the audit is complete, members can assess priorities in their energy efficiency plan based on recommendations made by the auditor.

Co-op’s Landfill “Brownfield” Transforming to Solar “Greenfield”

/in /by

San Miguel Power Association, GRID Alternatives Colorado and the Colorado Energy Office recently announced the development of a community solar array that will lower the electric bills of qualified low-income residents in SMPA’s service territory. The project is not only part of a statewide initiative to reduce energy costs for utilities’ highest need customers, it is also an effort to turn a limited-use site into a clean energy generator.

With an unwavering vision to reclaim a local landfill, San Miguel County worked with its partners in project development to turn a “brownfield” into a “greenfield” and harness renewable energy that will help the local community for decades to come. Project supporters also include Energy Outreach Colorado, the Telluride Foundation and EcoAction Partners.

According to SMPA Chief Executive Officer Brad Zaporski, the rural electric cooperative has been looking to increase its local renewable energy generation portfolio in a way that makes the resource available to a larger portion of its members and keeps utility bills affordable. Turning an old landfill into a site of local clean renewable energy generation adds an additional layer of benefit to the community and the environment.

“SMPA has long been a leader in energy efficiency and renewable energy,” said SMPA Board President Rube Felicelli. “We are now making home efficiency upgrades and local renewable energy readily available to our lower income members through SMPA’s ‘IQ’ or ‘income-qualified’ Weatherization and Solar Programs. We are excited to join with our partners to reduce our carbon footprint while also reducing the financial burden of high electrical bills on local families in need.”

“When we see projects like this, we are filled with optimism,” said Sandy Stavnes, acting assistant regional administrator for the Environmental Protection Agency. “With this project, community partners came together to turn property that had limited reuse potential into something that will provide energy to community members in need as well as significant environmental benefits. A bonus is the solar panels on top of the landfill will assure the landfill cover is maintained.”

This is the sixth low-income community solar demonstration project developed in partnership with local utilities through a $1.2 million grant GRID Alternatives received from CEO in August 2015. Each project is piloting a slight variation on the low-income community solar model to address the unique needs of rural utility service areas and their customers. The projects selected are both affordable and scalable for utility partners and offer great potential to expand across the state.

“This project, with its multiple bottom lines — energy cost saving for families, renewable energy, brownfield reclamation, and local solar job training — is a win for the whole community and a model for the state and the nation,” said Chuck Watkins, executive director of GRID Alternatives Colorado.

Colorado Energy Office Director Jeff Ackermann said, “This demonstration project with GRID and SMPA reinforces our low cost approach to community solar, which blends the delivery of clean-generated electricity and assisting our neighbors in need.”

Electric Vehicle Charging Station Energized in Co-op Territory

/in /by

Lake City’s first public electric vehicle charging station was recently energized and available for locals’ use. Gunnison County Electric Association was awarded another grant from the Colorado Energy Office’s Charge Ahead Colorado program, which helped cover the costs of the equipment and installation of the level 2 multi-port electric vehicle charging station.

Charge Ahead Colorado promotes the use of electric vehicles and increasing electric vehicle charging station infrastructure around the state. The Gunnison-based electric cooperative partnered with the town of Lake City on the project. Lake City generously donated two parking spots on town-owned property and poured the concrete slab for the station. GCEA staff installed the station and performed some of the electrical work.

The central location allows electric vehicle owners the opportunity to charge their vehicle and walk short distances to the many shops and restaurants in Lake City and take in the beautiful scenery. The charging station is the same model as the stations located in Crested Butte and Gunnison, which offers ease of use and familiarity for electric vehicle owners traveling in the area. (The city of Gunnison owns the station located in downtown Gunnison and also received a grant to help pay for that station.)

GCEA is proud to offer another resource to allow electric vehicle owners opportunities to travel with confidence between communities, promote clean energy technologies and encourage the use of more electric vehicles in the area.

Electric Cooperative and Duke Energy Share Solar Project

/in /by

CORE Electric Cooperative (formally Intermountain Rural Electric Association), headquartered in Sedalia, recently signed a 25-year agreement with Duke Energy Renewables to buy the electricity generated on a 13-megawatt solar site, dubbed the Victory Solar Power Project. Duke Energy acquired the site from developer juwi Inc. The Victory Solar Power Project will power approximately 2,600 homes with solar electricity and recently began operating.

“Victory is our first solar project in Colorado, where we already have an operating wind energy site,” said Rob Caldwell, president of Duke Energy Renewables and Distributed Energy Technology. “It’s the 50th solar project in our growing U.S. renewables footprint, and juwi’s high-quality site marks another milestone in expanding our solar presence in the western part of the country.”

“IREA (CORE) is pleased to have worked with juwi to bring this facility into production ahead of schedule,” said IREA Chief Executive Officer Patrick Mooney. “We look forward to Duke Energy providing clean renewable energy to IREA’s (CORE) customers for years to come.”

Leadership in a Purple State

/in /by

By Kent Singer, CREA executive director

If you are in a certain age group and attempted to learn the guitar as a teenager, I bet you mastered as least one riff: the opening notes to the 1972 Deep Purple hit “Smoke on the Water.” (You know it: bump, bump, bum…bump, bump, da-dum…bump, bump, bum…bump-bum.) And while the English bandmates who formed Deep Purple probably didn’t have Colorado in mind (despite the name of their biggest hit), the band’s name aptly describes the current balance of political power in Colorado.

At both the state and federal level, we have an equal mix of Republicans and Democrats in control of our legislative and executive branches. In fact, voter registration in Colorado is split fairly evenly among Republicans, Democrats and unaffiliated voters. So where some states are reliably blue (Democrat) or red (Republican), when it comes to political majorities, Colorado is reliably purple.

Purple state
Colorado has one Republican U.S. senator and one Democrat U.S. senator. In the 2016 election, Democrat incumbent Michael Bennet defeated Republican Darryl Glenn in a race that turned out much closer than the polls predicted. Even though Bennet raised and spent much more money than Glenn, his margin of victory was only 3 percentage points.

Republican incumbent Cory Gardner was elected in 2014 when he defeated the favored Democrat incumbent Mark Udall. The results of that race seemed to put on hold on what appeared to be a trend toward a Democrat-leaning electorate in Colorado.

The same purple theme applies to our congressional delegation. Of Colorado’s seven members of the U.S. House of Representatives, four are Republicans and three are Democrats. The three Democrats (Reps. Diana DeGette, Jared Polis and Ed Perlmutter) represent primarily Denver and the suburbs near Denver, while the four Republicans (Reps. Ken Buck, Mike Coffman, Doug Lamborn and Scott Tipton) represent the rural areas of the state, as well as urban counties farther from Denver.

At the state legislative level, the purple theme continues. The state senate has a narrow (18-17) Republican majority, while the Democrat majority in the House of Representatives expanded to 37-28 after the 2016 general election. This balance of power means that only legislation that has bipartisan support will pass during the next two sessions of the Colorado General Assembly.

Since the political activities of the Colorado Rural Electric Association are focused at the state level, the composition of the General Assembly and CREA’s relationship with its members is critical to the success of CREA initiatives. CREA’s legislative team is devoted to informing and educating state legislators about the cooperative difference and how legislation can impact the consumer at the end of the line. The CREA team also works hard to share with legislators and other stakeholders the extraordinary work being done by Colorado electric co-ops to respond to the changing demands of electric consumers.

Balanced leadership
With Colorado’s term limits, the leadership in both houses of the General Assembly changes frequently. Since the individuals in leadership positions set the agenda for their respective houses, we president of the Senate.

Rep. Crisanta Duran (D-Dist. 5)

For the two years of the 71st General Assembly (the 2017 and 2018 sessions), the speaker of the House will be Rep. Crisanta Duran. Rep. Duran will serve her fourth term in the legislature representing House District 5 in central Denver. Rep. Duran served as the chairwoman of the Joint Budget Committee in 2014, and she served as the majority leader in the 2015 and 2016 sessions. She sponsored a variety of legislative initiatives, including efforts to spur economic development, extend unemployment benefits for Coloradans learning new workforce skills and increase the renewable energy requirements applicable to Colorado’s electric co-ops.

Speaker-designate Duran has a particular interest in rural economic development: “One of my priorities has been to make sure that small businesses thrive and folks have good jobs in rural Colorado. That’s why I passed a bill to provide tax benefits to new businesses through creating ‘jump-start zones’ in rural areas of the state. I’m going to continue to make sure we don’t take anyone in Colorado for granted and leave no one behind.”

Although Rep. Duran does not have any electric co-op service territory in her legislative district, she is familiar with Colorado’s electric co-ops. She joined in support of recent legislation revising the co-op requirements under Colorado’s renewable portfolio law, as well as adjustments to the co-op election law.

During the 2013 legislative session, Rep. Duran was the prime house sponsor of S.B. 13-252, the bill that increased the renewable energy requirements for the co-ops. Since the passage of that bill, the work done by Colorado’s electric co-ops to integrate additional renewable energy into their power supply portfolios has not gone unnoticed by Rep. Duran: “I applaud efforts by local co-ops to generate more electricity from renewable sources. It’s really inspiring to see folks in Colorado taking the lead to make sure we can tap our wind, water and sun to create the energy we need and keep it in our communities.”

Sen Kevin Grantham (R-Dist. 2)

The Senate president for the 71st General Assembly will be Sen. Kevin Grantham, a two-term state senator from Cañon City. Sen. Grantham represents Senate District 2, a district that includes Fremont, Teller, Park, Clear Creek and parts of El Paso counties. Sen. Grantham was raised in a farming community in Crowley County and currently works as a real estate appraiser at Grantham Appraisal Service in Cañon City. He is also a member of the Joint Budget Committee, a position he will relinquish when he assumes his role as Senate president on January 11.

Sen. Grantham has long been a supporter of Colorado’s electric co-ops, and he was the prime Senate sponsor of several bills recently initiated by CREA. During the 2015 legislative session, Sen. Grantham sponsored a bill that allowed co-ops to use purchases from community solar gardens to comply with the requirements of Colorado’s renewable energy law. S.B. 15-046 also authorized electric co-ops to subtract their sales of electricity to industrial loads for purposes of calculating their “retail” distributed generation obligation. These changes made compliance with the renewable portfolio law more economic for co-op consumers.

In the 2016 session, Sen. Grantham sponsored CREA’s bill to make sure that all ballots are counted in co-op board elections and to reduce the costs of those elections. He also co-sponsored a bill that clarifies that sales of electricity for residential purposes are not subject to the state sales tax.

Sen. Grantham believes strongly in the idea that electric co-ops are successful because they are owned and governed by their members, and maintaining this independence is important: “Colorado’s electric co-ops have done a great job providing safe, reliable and affordable electricity to rural Colorado for over 75 years. The co-op business model and local control works, and we’ll oppose any proposed interference with that local control.”

Sen. Grantham’s take on renewable energy is somewhat different than Speaker-designate Duran’s view. “Our caucus tends to believe that market forces should determine which energy sources are used by Colorado’s citizens,” he says. “Although we support all forms of energy, including renewable energy, we don’t support mandates that increase costs to rural consumers.”

Working together
So, will a Senate president- designate from rural Colorado and a House speaker-designate from Denver be able to work together to solve Colorado’s problems and move the state forward? The answer from both is a resounding “yes.” Says Rep. Duran: “I look forward to working with Sen. Grantham, and across the aisle, to move Colorado forward in areas where I know we have common ground, including education, transportation and infrastructure. We have more in common than divides us, and I know we can work together to have a productive legislative session.”

Sen. Grantham concurs: “We won’t always agree with bills passed by the House and they won’t always agree with bills passed by the Senate. But I think we can still work together to balance the budget and find ways to spur economic development in rural Colorado.”

The band Deep Purple continues to tour, with different members, decades after its founding. And it looks like Colorado’s purple politics will also share the stage for the foreseeable future… bump, bump, bum…bump, bump, da-dum…bump, bump, bum…bump-bum.

How an Electric Utility’s Transformers Work

/in /by

By Tom Tate
300x250-industryIf you were asked to describe your electric cooperative’s system, you might say, “Poles, wires and those round gray things.” Round gray things? That is often the description given for transformers, the pieces of equipment crucial in converting electricity to a voltage that is safe for use in homes and businesses. So, how do they work?

First, transformers are nothing like those creations of the silver screen. They don’t transform from vehicles to incredible combat robots. Instead, they transform the voltage of the electricity that passes through them.

Here’s how they work: Electricity loses voltage as it is transmitted due to the resistance in wires and other components. As a result, higher voltages are used to offset these “line losses,” as electric utilities call them. It all starts at the power plant. There, generators produce electricity at high voltages and use transformers to step up this voltage. For example, in Colorado, Tri-State Generation and Transmission — the power supplier for 43 not-for-profit electric cooperatives and public power districts in Colorado, Nebraska, New Mexico and Wyoming — sometimes steps electricity it generates up to 345,000 volts. Since the power plants are far away, these voltages are necessary to survive the trip over the system to where it is needed.

Transmission lines connect to substations full of transformers and other control gear. Here is where the transformers step down the voltage to safer, more manageable levels. Depending upon the distance involved to the farthest member and the amount of load served, distribution voltages can range from 7,200 to 24,900 volts. A couple more step-downs and the electricity arrives at your home at 120/240 volts. This is quite different from the original voltage.

Regardless of the shape and size of the transformer, they all work in the same manner. Transformers have two sides, a high-voltage side and a low-voltage side. In normal operation, electricity flows into the transformer on the high-voltage side where it goes into a coil of wire, usually wound around an iron core. As the electricity flows through this coil, it creates a magnetic field that “induces” a voltage in the other coil. Here is where the magic (aka physics) of transformation takes place. Each coil has a different number of turns. The greater the number of turns, the higher the voltage. The coil on the high side will have more turns than the one on the low side. As a result, the voltage induced on the low side is less. Then transformation occurs.

Transformers aren’t just limited to utility use. They can be found everywhere in our daily lives, even if not so obvious as those on your electric cooperative’s system. The best example is the charger that all cell phones and many other electrical devices come with. These small cousins of utility transformers basically perform the same function. Charging your cell phone with 120 volts will fry it instantly. So, the charger converts the voltage to a more tolerable direct current. Take a moment to look around your home and see just how many of these miniature transformers you have. You might be surprised.

It is important to note that transformers work in both directions. Electricity flowing in on the low side is stepped up to the voltage of the high side. This is why electric co-ops educate members on proper connection of home generators. A generator feeding 240 volts into a residential transformer will produce whatever voltage the transformer is rated for on the other side, creating a deadly risk for line crews and your neighbors, which is why your co-op asks you to connect your generators according to the manufacturer’s recommendations. It’s always best to be safe.

Co-ops Care About Veterans in the Workforce

/in /by

By Justin LaBerge

Most military bases are located in rural areas, and the power systems at some bases are operated by electric cooperatives. A disproportionately large percentage of our nation’s troops — some estimates suggest as high as 40 percent — come from rural America. Even the organization responsible for representing electric cooperatives in Washington, D.C., the National Rural Electric Cooperative Association, was once led by a retired Army general.

Last year, America’s electric cooperatives began a new chapter in their long history of support for the military with the launch of Serve Our Co-ops, Serve Our Country, a nationwide initiative to honor and hire military veterans and their spouses.

The program was developed to help electric cooperatives address a generational turnover in their workforce. Over the next five years, NRECA estimates electric co-ops will need to hire approximately 15,000 new employees to replace retiring baby boomers.

Those new workers will fill roles in every department, from lineworkers climbing poles to member service representatives answering questions to engineering and industrial technology experts designing and managing a smarter electric grid.

In addition to the technical skills these jobs require, electric cooperative employees must be hard working, disciplined, loyal, safety conscious and team oriented — qualities that are common among military veterans.

This summer, Serve Our Co-ops, Serve Our Country celebrated a major milestone when former Air Force Capt. Jeremiah Sloan became the first veteran officially hired through the program.

The story of how Sloan landed his new job as an electrical engineer at Craighead Electric Cooperative in Jonesboro, Arkansas, reads like the plot of a Hollywood movie.

Brian Duncan, CEO of Craighead Electric in Arkansas, hired the first veteran at the nation's co-ops.

Brian Duncan, CEO of Craighead Electric in Arkansas, hired the first veteran at the nation’s co-ops.

For several months, Craighead Electric CEO Brian Duncan worked to fill the position. Duncan advertised the opening in local papers and national job sites and attracted a number of highly qualified candidates.

Sloan’s application was among those strong candidates, but he wouldn’t be available to start for six months when his Air Force service ended.

Duncan, hoping to fill the position sooner than that, made offers to two other well-qualified applicants, but was unable to come to terms with either.

Shortly after the second candidate fell through, Duncan attended a national conference for electric cooperative CEOs.

One of the sessions featured two fellow co-op CEOs, one of whom was a 25-year Air Force veteran, discussing the newly launched veteran hiring initiative.

“The whole time they’re talking I’m thinking about Jeremiah; we probably need to look at this guy. For these guys coming out of the military, what better way to say ‘thank you’ than to give them a job,” Duncan said.

Jeremiah Sloan on the job.

They scheduled an interview and it didn’t take long for Duncan to realize the co-op found its next engineer in Sloan.

“He was extremely professional. It was straight down the line. ‘Yes, sir.’ ‘No, sir.’ Very detailed in his answers to all of the questions. Very thoughtful in his answers. It was the perfect interview, you might say,” Duncan said.

Sloan brings more than a strong resumé and professional demeanor to his new position at Craighead Electric. He also brings a love for the community and a desire to return to his roots.

“I grew up in northeast Arkansas,” Sloan said. “My family is a long line of farmers, and they’re actually on Craighead Electric’s lines. The whole reason my wife and I decided to separate from the Air Force was to return home and be close to family.”

Former Air Force Capt. Jeremiah Sloan is the newest engineer on the Craighead Electric Cooperative team. “Sloan brings more than a strong resumé and professional demeanor to his new position, " CEO Brian Duncan said." He also brings a love for the community and a desire to return to his roots.”

Though Sloan is the first veteran hired through the initiative, he won’t be the last; several other veterans have already been hired through the program. In addition to nationwide outreach through NRECA, approximately 50 electric cooperatives across the country already took the pledge to join the effort on the local level.

The support of veterans and reservists extends far beyond the scope of the formal Serve Our Co-ops, Serve Our Country program into the routine operation of many electric cooperatives.

Two managers at AECI, a wholesale supplier of electric equipment owned by the electric cooperatives of Arkansas, were recently honored by the U.S. Marine Corps for their support of a Marine reservist working at the cooperative’s warehouse in Stillwater, Oklahoma. In August, Russ Dilley and Eric Creekmore were presented the Patriot Award for giving AECI truck driver Michael Henderson the workplace flexibility he needs to serve in the Marine Corps Reserves.

Serve Our Co-ops, Serve Our Country is another way America’s electric cooperatives can show concern for community while building a next generation workforce that will deliver the exceptional service co-op members expect and deserve.

Could Allam Cycle Be a Cleaner Solution for Colorado’s Electric Co-op Coal Plants?

/in /by

The U.S. Environmental Protection Agency’s Clean Power Plan raised more questions than answers since the rule’s finalization in August 2015.

Basin Electric Power Cooperative, a not-for-profit generation and transmission cooperative that provides supplemental power to rural electric cooperatives in nine states, including Colorado, has an energy portfolio that includes coal, gas, oil, nuclear, distributed and renewable energy. With nationwide focus shifting toward renewable energy, Basin Electric’s leadership understands the cooperative must evolve to continue growing in a carbon-constrained world. One technology that is flashing economical carbon-reduction potential is the Allam Cycle.

The vision for the Allam Cycle consists of gasifying lignite coal to produce synthetic natural gas, which would then be used along with oxygen and carbon dioxide to drive a turbine generator.

screen-shot-2016-10-26-at-1-51-41-pm-copyThis working fluid is then cooled through a heat exchanger and water is separated from it to create a nearly-pure CO2 stream. The CO2 stream is pressurized and a majority of the flow is fed back to the combustor as the working fluid to begin the cycle again. The remaining part of the CO2 flow is collected and put into a pipeline without increasing the power plant’s cost of producing electricity.

The technology could provide Dakota Gasification Company another source of marketable CO2 to be used for enhanced oil recovery or other purposes, and provide Basin Electric a more efficient and CO2 emission-free way of generating electricity using lignite coal.

Jim Sheldon, Basin Electric senior research and design engineer, heads the cooperative’s Horizons Committee. The group is responsible for monitoring and disseminating information regarding major environmental issues and new technologies — one being the Allam Cycle.

“This cycle uses CO2 as the working fluid instead of water, which we currently use in our coal plants. The first advantage is the dramatic efficiency gain using CO2 since it stays in the vapor phase instead of changing from liquid to vapor and back,” Sheldon says.

“Secondly, the combustion products in this cycle can be sent directly to a turbine to generate electricity.”

To research further development of Allam Cycle technology and its use with lignite coal, Basin Electric; the Energy & Environmental Research Center; 8 Rivers and ALLETE, Inc., along with ALLETE subsidiaries BNI Coal and Minnesota Power, were granted $1.48 million toward the total $3.18 million one-year research project.

Basin Electric and ALLETE also committed to contributing matching funds and in-kind services supporting the work.

A first-of-a-kind plant using natural gas will start up in Texas in 2017, along with a more in-depth study using lignite to make synthetic natural gas in North Dakota. Basin Electric will monitor the technology’s development and participate in the North Dakota study.

“If the first-of-a-kind plants prove out the initial work, this technology could be an economical means of using coal in a CO2- and emissions-constrained future,” Sheldon says.

Community Solar Coming for West Slope Co-op

/in /by

Delta-Montrose Electric Association, which serves Delta, Montrose and Gunnison counties, partnered with GRID Alternatives to develop a 150-kilowatt community solar array, specifically for members qualified as low-income. Once the project is complete, participants can take advantage of locally-produced solar power and experience long-term energy savings. Other benefits include energy efficiency and basic solar education, full support and paperwork assistance, and no maintenance or installation requirements for participants. On average, participants will save up to 50 percent on their bill.
