The award-winning, 40-kilowatt (kW) Capture the Sun Community Solar Garden went online in 2015, after public outreach indicated strong support for more solar options. Moorhead customers pay for the power output of one of the 144 non-rotating, photovoltaic (PV) panels that make up the array. The value of the energy generated by the panels is prorated annually in the form of bill credits to participating customers. MPS is responsible for ongoing maintenance and delivering the energy to subscribers’ homes and businesses.

“The point of the gardens is to allow people who don’t have the ability to have solar panels at their home, to help feed solar energy into the grid,” said MPS Energy Services Manager Dennis Eisenbraun. “That fits the criteria for the Energy Innovator Award very well.”

The award recognizes utility programs that demonstrate advances in the development or application of creative, energy-efficient techniques or technologies. Judges also look for programs that improve service to electric customers or projects that increase the efficiency of utility operations or resource efficiency. Transferability and project scope in relation to utility size are also considered. APPA presented the award during its annual National Conference in June in Phoenix, Arizona.

Keeping customers satisfied
Although support for clean energy—especially the home-grown kind—is strong among consumers, many homes and businesses are not in the position, literally or figuratively, to install solar. According to the National Renewable Energy Laboratory, about three-quarters of all buildings are not suitable for a solar array due to shading, roof orientation, structural issues and other concerns.

Shared solar, however, has the potential to greatly increase consumer access to solar PV, a fact not lost on MPS customers. “We did an initial survey to gauge customer interest last year, and then held a couple of public meetings,” Eisenbraun recalled. “Finally, we sent out a mass mailing seeking a commitment to the project and there was an overwhelming positive response.”

Capture the Sun quickly attracted more subscribers than it had panels to accommodate them. “We knew before we finished building the 2015 project that it was only going to be ‘Phase One,’” said Eisenbraun. “Between the waiting list and a second mass mailer sent earlier this year, we had enough support to go ahead with another array in 2016.”

Poised for success
The second phase of Capture the Sun will be fully subscribed when it goes online this fall. MPS is planning a public dedication, Oct. 4, during Public Power Week.

The success of the solar garden is not surprising, given that Moorhead residents are already familiar with the concept of community renewable energy development. MPS built two wind turbines, one in 1999 and another in 2001, and more than 800 customers signed up to support the Capture the Wind program with a small green power tariff on their monthly electricity bills. “Our first foray into renewable energy was a resounding success,” Eisenbraun acknowledged. “The turbines were a great public relations tool and they reached payback in just 11 years, four years ahead of schedule.”

Going local
Like the wind turbines, Capture the Sun is a distinctly local project that keeps control in the community and the economic benefits within the region. MPS self-financed the solar garden with a combination of subscriptions and funds shifted from its renewable system incentive program. “We didn’t have as many individual customers installing systems as we hoped,” explained Eisenbraun. “So instead of leaving that money on the table, we decided to use it to give our customers another option.” A very popular option, as it turned out.

MPS also chose Enterprise Sales Co. You are leaving WAPA.gov. from nearby Valley City, North Dakota, to build the project. The website states that Enterprise is “more than a contractor,” but Eisenbraun was surprised to learn that the company builds solar arrays. “I was only familiar with them as grain bin builders,” he admitted. “But they came in with the best price and their project manager worked everything out to the finest detail.”

At Moorhead Public Service, bringing recognition to a local business, self-financing community renewables projects and giving customers what they want is not so much about innovation as it is about doing the right thing. “We didn’t build Capture the Sun because of any mandates,” Eisenbraun pointed out. “We did it because it was a great idea and our customers thought so, too.”

And that kind of thinking deserves an award.

Rural customers develop efficiency, renewable projects with REAP funds

The June 30 deadline is approaching for the final round of grants and guaranteed loan financing from the Department of Agriculture’s (USDA) Rural Energy for America Program (REAP).

REAP funding helps agricultural producers and rural small businesses purchase and install renewable energy systems or make energy efficiency improvements. Western customers are among the electric cooperatives, communities and businesses that have benefited from the program.

Making difference in Midwest
Agricultural communities in the Midwest face many economic challenges in spite of the region generally enjoying low-cost power. Since the program’s inception in 2002, REAP has contributed to the economic health of this part of the country by helping farmers and small businesses reduce operating expenses. Rural electric cooperatives have used REAP funding to diversify their resource portfolios.

Nobles Cooperative Electric You are leaving WAPA.gov. in Worthington, Minnesota, was an early REAP recipient. When the state legislature began considering a statewide renewable electricity standard, the co-op applied for a grant to install a utility-scale wind turbine in its territory. In addition to the $500,000 REAP grant, Nobels received $2.5 million through Clean Renewable Energy Bonds from the National Rural Utilities Cooperative Finance Corporation You are leaving WAPA.gov. (CFC) to fund renewable energy projects. General Manager Richard Burud noted that the CFC and USDA assistance made the difference between doing the project and not doing the project.

Increasing irrigation efficiency
In the dry western farming region of all-public power Nebraska, growers rely on irrigation systems that use great quantities of both water and energy.  Many irrigation systems are powered by diesel engines, which have high carbon emissions and expose farmers to volatile fuel costs. Nebraska Public Power DistrictYou are leaving WAPA.gov. one of the state’s largest electric providers , teamed up with USDA Rural Development staff in 2004 to help more than 200 farmers receive REAP (then called Section 9006) grants to replace diesel or propane-fueled irrigation motors with electric motors.

Close cooperation was critical to the program’s success. Rural Development did extensive outreach to growers, focusing on irrigation projects, while NPPD staff conducted the energy assessments needed to apply for the grants. “We continue to support REAP projects by doing energy audits for applicants,” explained NPPD Energy Efficiency Consultant Ron Rose. “Audits performed by a certified energy manager earn more points for the applicant in the USDA scoring process.”

The farmers did their part too, working through the application process to receive grants that averaged around $7,000 per system. “The grants don’t pay for the whole project, but they lower the payback period considerably,” acknowledged Rose.

Given the fuel prices at the time, farmers were able to save as much as 30 percent of their irrigation energy costs by converting from diesel to electric. Rose noted that even though fuel prices have dropped, the electric pumping systems are still popular because remote management technology works better with electric equipment. “The farmers are able to control irrigation from their smart phones or tablets,” he said.

Helping customers helps utility
The REAP project stabilized energy cost for the applicants, gave them greater control over their systems and has encouraged some growers to move to solar powered pumps. Investing in energy efficiency can increase the income for a farm or business, and buying and installing new equipment creates economic activity in the community.

An economically healthier community is always good for a public-power utility. More directly, moving some of its larger customers from fossil fuel to electric power adds to NPPD’s customer base. Other REAP projects, such as solar grain dryers and building envelope upgrades for small businesses, promise future benefits for peak load control while keeping the local economy strong.

Rose urges customers to contact their local USDA Rural Development offices You are leaving WAPA.gov. to get their applications as soon as possible. Power providers may help support applications by providing energy audits. Also, keep in mind that REAP is a grant rather than a rebate, advises Rose. “Complete the application before you start the project.”
