In Western Colorado, there is a group of small-hydro pioneers working with their local electric cooperatives. These individuals re-contextualized a very old and well known concept and are truly transforming the regional and national opportunities for hydropower generation. To successfully develop a small hydro generating system it takes vision, persistence and risk. Three of these pioneers are members of San Miguel Power Association:

Project One: Owned by the city of Ouray and built off an abandoned 6-inch water line that ran through town, this hydro facility is the product of a visionary citizen and former mayor of Ouray, Bob Risch. Up against funding, engineering and construction challenges, Risch’s vision became a community-building, energy-harnessing, money-saving reality.

Project Two: The San Juan Historical Society Mayflower Mill hydro-plant in Silverton. In order to become a legally established generator, small hydro plants such as this one had to tackle onerous federal regulations originally developed for projects like the Hoover Dam. Usually, such regulations become deal breakers for such small systems. But because of the influence and persistence of Mayflower Mill developers like Beverly Rich and Kurt Johnson, federal regulations were drastically improved to make licensing for small hydro projects attainable. New regulations for this and other small hydro projects were established because of their persistence.

Project Three: Located in Nucla and single-handedly developed by Terry Boekhout, this hydro facility came to be despite the risky environment that shrouds nearly every aspect of hydro-electricity generation. Unknown project costs, elusive government and utility incentives, tricky National Electric Code requirements and the utility net metering policy were all obstacles in the development of this small-hydro facility. Boekhout was the glue that kept the construction of the project, including the penstock, the inlet and outlet, the generator house, the overall design of the site, and all the other unknowns, from flying out of control.

While the challenges are many, each project has been made possible through the efforts of these passionate individuals and the cooperation of their local electric cooperative. Each hydro project is vastly unique, but each is also driven by individuals who are willing to transcend the risk move ahead with their vision. This is the true mark of a pioneer.

A 130-acre solar farm three miles east of downtown Fort Lupton is now producing power. The project began in late 2014 after Brighton-based United Power initiated an effort to incorporate cost-effective renewable energy sources to help meet renewable energy goals.

Partnering with solar developer Silicon Ranch Corporation, Silicon Ranch will own and operate the solar farm, while United Power receives all the energy produced over a 20-year period.

The 13-megawatt farm is expected to produce about 30 million kilowatt hours of electricity per year from approximately 150,000 solar panels – enough to power 3,100 homes. The solar field is a single axis tracker, which means that the panels follow the sun throughout the day. This generates about 25 percent more energy than a traditional fixed panel system.

“Not only does this solar field significantly contribute to United Power’s overall renewable generation portfolio,” said Jerry Marizza, new energy program coordinator at United Power. “But it also makes business sense by helping United Power stabilize future rates to all its members.”

The Fort Lupton solar site, along with other renewable projects, helps United Power meet its statutory legal requirements to have 20 percent of its generation produced with renewable energy. It also generates a margin for United Power which correspondingly helps all its members by stabilizing future rate increases.

A collaborative effort between three renewable energy supporters made Empire Electric Association’s Solar Assist Cooperative Garden a reality. The story of the partnership between the Cortez-based electric co-op and GRID Alternatives, a nonprofit from California, started when GRID reached out to EEA through the Colorado Energy Office.

By February 2016 the agreement was in place between EEA and GRID and construction began. The arrays were completed in April, thus making EEA the first system in the state of Colorado to partner with the Colorado Energy Office and GRID.

GRID received $1.2 million in grant money from the Colorado Energy Office to partner with Colorado co-ops and bring community solar to low-income families. GRID made a proposal to EEA for the installation of the 70 solar photovoltaic panels that produces 21.35 kilowatts in these arrays. In addition, GRID promised to be on site to train and lead teams of community volunteers and job trainees installing the solar structure. Through this program, five to 10 qualifying EEA members will see a reduction on their electric bills depending on how much energy the arrays generate.

EEA General Manager Josh Dellinger said, “The board feels that projects like this that benefit our community are in the best interest of our members as a whole. EEA has a long history of donating to organizations with various needs in our community and is glad to support our members.”

The volunteer solar installers included three Empire Electric employees, including Dellinger, as well as Montezuma-Cortez High School senior students, potential solar subscribers, student trainees from the Navajo Technical University in New Mexico and residents from Cortez.

The preparation for the expansion was completed and ready for the volunteers to finish the project in two days. Upon arrival, the volunteers were issued a hard hat, safety glasses, work gloves and a reflective vest. GRID divided the community volunteers into work teams headed by a GRID team leader. The volunteers got to work and eagerly helped assemble the arrays.

Dellinger volunteered on the first work day, helping install the framework for the solar panels to rest on. Dellinger said it was great to see potential subscribers contributing to the project. “It was also good to see volunteers from the high school participate,” he said. “It is nice when people come together on a project that will benefit members of our community.”

Day two included a dismal forecast of rain and snow. The job for the day was to secure and connect solar panels to the gleaming double tracks that were installed the previous day. Panel cables were attached to the inverters and the panels were secured using special fasteners. Once the cables were attached, a light flashed on the inverter, completing the connection.

EEA system engineer Clint Rapier volunteered at the project and was impressed by the preparation GRID Alternatives made: the preassembled tool kits, personal protective equipment, safety plan, briefing and organization. “It was apparent GRID had done this before and had refined the process,” Rapier said.

“Volunteering brings a sense of pride when working on projects for our community,” said EEA communications specialist Denise Moore, who also volunteered on the project. “Even though it was cold and we were soaking wet, everyone was there to get the job done. Working with such positive people made the job go quickly, and it was an inspiration to be involved in this uplifting community project.

The Solar Assist Cooperative Garden is located on EEA’s property in Cortez where it is maintained by the cooperative. Members can lease solar panels for a 20-year period and receive credit for the power generated by their panel.

Solar energy, generated from locally-based solar panels will soon be powering the homes of United Power members.

Silicon Ranch will own and operate the facility and United Power will buy and distribute the electricity over a 20-year period.In late 2014, Brighton-based United Power initiated an effort to incorporate cost-effective local renewable energy sources to complement the power it purchased from its power supplier. To help meet its renewable energy goals, United Power partnered with Silicon Ranch Corporation, one of the nation’s leading developers, owners and operators of solar energy facilities. Through that partnership, the local electric cooperative will buy the electricity generation by the 13-megawatt solar farm 3 miles east of downtown Fort Lupton.

“United Power’s staff worked diligently to acquire this project and to set the power purchase agreement into place for Silicon Ranch,” said Ron Asche, United Power CEO. “We are excited that all the production from this project will be used right on our own distribution system and will power nearby homes and businesses. United Power is a strong supporter of renewable energy, and this system will enhance our commitment of these resources.”

Once completed this spring, the 130-acre solar farm will generate 34.2 million kilowatt-hours of electricity per year from approximately 160,000 solar panels – enough to power 2,500 households.

Yampa Valley Electric Association, with offices in Craig and Steamboat, is one of five electric co-ops that has partnered with GRID Alternatives Colorado and the Colorado Energy Office to develop a community solar array that will be 100 percent dedicated to lower income YVEA members. Members participating in this program will receive a bill offset from the energy produced by their portion of a community solar array.

GRID Alternatives Colorado is a nonprofit organization that makes renewable energy technology and job training accessible to under served communities. GRID brings together community partners, volunteers and job trainees to implement solar power for lower-income households, providing energy cost savings, hands-on installation experience and a source of clean, local energy that benefits everyone.

An analysis from the National Renewable Energy Laboratory suggests that “between 50 percent and 75 percent of households and just over 50 percent of businesses are unsuitable to host photovoltaic systems on their roofs because of shade, orientation, structural factors or ownership issues.” In community solar gardens, participants get the benefits of energy from the sun as if the solar system was on their roof, but their solar panels are located offsite away from their home in a larger, shared community array.

With the GRID project, YVEA is choosing to experiment with owning, operating and maintaining the garden, unlike the co-op’s Clean Energy Collective Array in Craig which was built and managed by the developer of the solar garden. GRID will help YVEA build the new solar garden and support it over time.

To qualify for this program, participants must pay their own electric bill to Yampa Valley Electric and their total household income must be at, or below, 80 percent of the area median income of their county.
