Poudre Valley REA community solar project broadens access

Sometimes an idea is so good, you just want to be a part of it in some small way. That is how we at WAPA’s Energy Services felt when we learned that Poudre Valley Rural Electric Association You are leaving WAPA.gov. (PVREA), one of our customers, was building a community solar array with GRID Alternatives Colorado You are leaving WAPA.gov. to serve its low-income and nonprofit customers.

Solar for all
The Coyote Ridge Solar Farm will cover nine acres near the Larimer County Landfill with more than 6,000 320-watt solar panels on a tracking system that follows the sun across the sky. PVREA will make 700 kilowatts (kW) of the 1,962-kW array available to low-to-moderate income subscribers and 500 kW for nonprofit organizations in the utility’s service territory. It will be the nation’s largest community solar project of its kind, and demonstrate complex financial modeling and unique siting.  PVREA has partnered with the nonprofit solar installer GRID Alternatives Colorado and the Colorado Energy Office You are leaving WAPA.gov. to develop the project.

In August of 2015, the Colorado Energy Office made a $1.2 million grant to GRID Alternatives Colorado for the express purpose of partnering with utilities to implement low-income community solar projects. That focus fit right in with a specific concern of the PVREA board of directors, noted the utility’s Alternative Energy Administrator Milton Geiger. “They were looking for a project that would bring the benefits of solar power to a greater number of our members,” he said. “Our board believes that equitable access to solar power is a cooperative principle.”

Learning by doing
Coyote Ridge is the seventh project to receive funding from the grant. Originally, the plan was to develop at least five different low-income solar projects with the grant, but GRID Alternatives knows how to stretch a funding dollar and build in community participation at the same time.

Designing a community solar array is a complex task, but assembling the parts calls mostly for elbow grease.

Like Habitat for Humanity, an organization to which it is frequently compared, GRID Alternatives invites individuals and community groups to participate in both residential and commercial-scale solar installations. Although designing a solar array is a complex task, assembling the racking and setting modules turn out to be mostly measuring, lifting, lining up and tightening screws. Low-income homeowners and church and community service groups can participate in building the facilities that will lower their energy costs and reduce their carbon footprint. More importantly, for those interested in long-term careers in the field, GRID Alternatives provides hours of hands-on training.

WAPA gets involved
The project came up during discussions at a community solar workshop WAPA hosted in early June. At first glance, it had everything we love to cover in Energy Services Bulletin stories: a WAPA customer developing renewable energy for the benefit of members who need it most. More than a third of the electricity produced will be offered at a reduced rate to PVREA households with income levels at or below 80 percent of their county’s median. When Geiger later explained GRID Alternatives’ involvement, and the volunteer opportunity, the story became irresistible.

So on a cold, rainy September morning, Energy Services Director Ron Horstman, Electronics Engineer Kevin Hogg and Energy Services Marketing Coordinator Kevon Storie (me) showed up at the site near the Larimer County Landfill, ready to build some solar. For a little background, our personal experience with solar construction runs the gamut. Horstman installed a 3.2-kW solar array on his own home in 2009, while it was Hogg’s first time working on an installation. I have—well—I’ve seen a lot of pictures of photovoltaic systems.

Satisfaction guaranteed
The crew was 53 strong that day, including several individuals, a group from a Unitarian church and engineering students from the Colorado School of Mines, Colorado State University and Denver University.

When we arrived, the rack for the lower half of the array was partially assembled, but many hands made light work. The crew first learned to install the vertical “arms” that hold up the solar modules, and then moved on to mounting the modules themselves. Shortly after lunch, the array was completely assembled and ready to be wired by professional electricians in the coming week. The crew put up a total of 999 solar panels and continued working on the racking on the second section of the solar farm.

The work was hard and the weather was dreary, but the experience was enlightening. Hogg, who lives in Loveland, Colorado, was gratified to see community engagement in action, and is now interested in adding a solar array to his home. Horstman enjoyed talking to the students about their studies and about WAPA. (Note to utilities and related industries: Volunteering for GRID Alternatives is a great way to meet intern candidates.) For my part, I increased my minimal understanding of solar construction and was delighted to see so much progress in the space of a single day.

Size, site matter
PVREA joins other WAPA customers in working with GRID Alternatives and the CEO. Empire Electric AssociationYou are leaving WAPA.gov. Delta Montrose Electric AssociationYou are leaving WAPA.gov. Holy Cross EnergyYou are leaving WAPA.gov. Yampa Valley Electric AssociationYou are leaving WAPA.gov. Fort Collins UtilitiesYou are leaving WAPA.gov. San Miguel Power AssociationYou are leaving WAPA.gov. and Grand Valley Power You are leaving WAPA.gov. have all been partners in developing community solar farms that offer solar credits to low-income subscribers. Once constructed, the facilities become utility-owned assets.

Each installation demonstrates a unique characteristic that makes it work for the utility. In the case of PVREA, Coyote Ridge is sited on a large tract of unused land next to the Larimer County landfill that will have minimal environmental impact. The size of the farm is another key aspect of the project. “It drives the economy of scale and makes it replicable for other utilities,” said Geiger.

Replicability is central to the Low-Income Community Solar Demonstration Project. GRID Alternatives, the Colorado Energy Office and utility partners are demonstrating that the benefits of renewable energy are for everyone, one solar installation at a time.

Long road leads to solar success for Southern Ute tribe

Tenacity paid off for the Southern Ute Indian Tribe on July 24, when they dedicated their newly commissioned and fully operational Oxford Solar Project on the Southern Ute Indian Reservation in Ignacio, Colorado.

The Southern Ute Tribe built their solar array on the mostly unusable Oxford Tract near a substation and just three miles from the tribal building campus.

The years it took to develop the 1.3-megawatt (MW), ground-mounted solar photovoltaic (PV) system ultimately ensured that the project was a winner for all involved. The array will reduce operating costs for the tribe by offsetting about 15 percent of the energy used by 10 tribal buildings. The siting of the project repurposes more than 10 acres of tribal land that was mostly unusable due to naturally occurring selenium contamination. The Oxford Tract, as the land parcel is called, has strong solar resources, is located near two substations and does not have any endangered or threatened species on it. La Plata Electric AssociationYou are leaving WAPA.gov. which is purchasing the power and providing the grid connection, counts the electricity toward its goal of 20 percent local generation by 2020.

Slow start gathers steam
The Southern Ute Tribe first began to explore the idea of building a PV system in 2006 as a way of diversifying its business interests, and launched the Southern Ute Alternative Energy LLC (SUAE) in 2008. As a for-profit business, the SUAE evaluated solar PV development opportunities on tribal lands from a business perspective. For several years, alternative energy projects remained stubbornly out of reach, too costly for SUAE to pursue.

The turning point came in 2011 when the tribe performed a new feasibility study to look at potential sites and business models. James Jensen, who had recently joined the SUAE staff, recalled that the study was very thorough. “We were open to projects either on or off of tribal land,” he said. “If it was on tribal land, what was the best location? We evaluated environmental factors like whether the land was arable or disturbed or in a floodplain.”

The study also considered the proximity of transmission and substations to potential sites and did economic modeling on hypothetical projects. “We came out of the process with a comprehensive understanding of what would make a successful solar project,” said Jensen.

The findings determined that the Oxford Tract was the most suitable location for a utility-scale solar development, and that a grant was needed to make the project economical.

JumpSTARTing project
Southern Ute Grant Specialist Jody Rosier began working with Jensen on the grant application to submit to the Department of Energy (DOE). Financial help wasn’t the only thing DOE had to offer the tribe, however.

Just as important, Rosier recalled, was the tribe’s participation in the Strategic Technical Assistance Response Team (START) Program. START, a program of the DOE Office of Indian Energy, provides technical assistance to help Native American tribes complete renewable energy and energy efficiency projects. “START analyzed and validated the findings of the feasibility study,” Rosier recalled, “and helped the tribe to establish a relationship with DOE.”

The program also helped the tribe determine the siting of the project near substations belonging to LPEA. “Initially, the project was planned as a ‘virtual metering’ situation, where any kilowatt-hours being generated would offset kilowatt-hours the tribe was using,” explained LPEA Engineering Manager Ron Meier. “Siting the array near a substation was key to making physics work. It really simplified the development process for them.”

Beyond that, Meier added, the purchase power agreement was pretty straightforward. With a budget of $3 million co-funded by the tribe and a $1.5 million grant from the DOE, it was time to start building.

Ready, set, install!
SUAE issued a request for proposals at the end of 2014 for an 800-kW system. It was around that time that the solar industry saw a significant drop in the price of panels. “We were pleasantly surprised when the bids came back to find that we could afford to build a somewhat larger project,” said Jensen.

The tribe chose Boulder, Colorado-based Namaste Solar to design the project for the tribe and install the tracking panels. Jody Rosier noted that tracking technology is becoming more common in new solar installations. “Panels that follow the sun across the sky generate more electricity and that improves a project’s economics,” she said.

The long process that culminated in the July 24 celebration provided the Southern Ute tribe with a thorough education in solar development. Jensen observed that the most important lesson they learned might be to keep the first project simple. He pointed to the selection of a site that did not require an environmental impact study as one factor that kept the project from getting too financially and legally complicated.

Although grants that require matching funds may put projects beyond a tribe’s reach, Rosier encourages tribes that are interested in developing renewable energy systems to investigate available grants. “Grants that require matching funds may not work for tribes,” she warned. “But once the renewable system is up and running, it provides years of sustainable electricity and needs little maintenance.”

Conference highlights initiatives worth imitating

Rocky Mountain Utility Efficiency Exchange
Aspen Meadows Resort
Sept. 27-29

Rolling into its second decade, the Rocky Mountain Utility Efficiency Exchange You are leaving WAPA.gov. has now been around long enough for its many participants to see the fruits of meeting annually to swap program ideas and stories of successes and failures with colleagues from across the region.

Utility program managers will be gathering at the Gold LEED-certified Doerr-Hosier Center at Aspen Meadows Resort Sept. 26-29 to share their ideas for taking customer efficiency programs to the next level.

Forward-looking agenda
This year’s theme, “Initiatives worth Imitating,” focuses on using lessons learned from past programs to address the new issues and opportunities utilities are facing. Programs incorporating time-of-use rates, community solar, the internet of things and big data will be in the spotlight. Sessions will also cover new spins on demand response, customer outreach, behavior change and incentive programs.

“Technology often integrates tools and strategies that were part of successful energy-efficiency and load management programs in the past,” explained Energy Services Manager Ron Horstman. “Load management today and going forward requires updates and changes in approach that will maximize the new resources and technology that are constantly being introduced to the industry. This year’s agenda encourages that kind of thinking.”

The future is on the minds of keynote speakers, too. Mark Martinez, the senior portfolio manager for emerging markets and technologies with Southern California Edison You are leaving WAPA.gov. will deliver the opening keynote, Preparing Today for an Integrated Demand Side Management Future. He will draw on his more than 25 years of experience in the design, management and evaluation of electric demand side management (DSM) programs to present a vision of how DSM needs to change.  

The closing keynote by Ellen Steiner, the vice president of Opinion Dynamics You are leaving WAPA.gov., will explore how utility customer programs can adapt to meet the needs of changing demographics. A master methodologist, Steiner has strong energy-efficiency industry experience encompassing workforce education and training, marketing, community outreach and HVAC program design and evaluation.

Hear from your peers
New and familiar faces host the regular sessions, including the dual track residential and commercial sessions on Thursday. Sponsors the City of Aspen You are leaving WAPA.gov. and Holy Cross Energy You are leaving WAPA.gov. will join Fort Collins Utilities You are leaving WAPA.gov., Colorado Springs Utilities You are leaving WAPA.gov., Nebraska Municipal Power Pool You are leaving WAPA.gov. and many more regional utilities to talk about the state of customer programs in 2017. Research agencies and nonprofits like Rocky Mountain Institute You are leaving WAPA.gov. and National Renewable Energy Laboratory team up with program vendors such as CLEAResult You are leaving WAPA.gov., Franklin Energy You are leaving WAPA.gov. and Nexant You are leaving WAPA.gov. to discuss the latest services and solutions available to help utilities manage their loads.

Friday offers a special treat with a focus on electric vehicles and storage. These topics were overwhelmingly popular at the 2017 Utility Energy Forum in California, and Rocky Mountain area utilities will be facing the same issues sooner than we expect.

Network toward your goals 
If the sessions are a great way to explore the nuts and bolts of program design and delivery, the networking opportunities let you take the pulse of the regional industry.

In addition to breaks and meals (pack your “comfortable” business casual wear), attendees will have plenty of time to mingle with their colleagues and swap ideas. On Wednesday, Sept. 27, grab a snack and a beverage and check out the poster session reception. These mini-presentations allow attendees to talk one-on-one with presenters about topics as diverse as community solar, connected home devices and infrastructure planning.

Relaxed networking continues Thursday night at the Limelight Hotel in downtown Aspen. This venue provides a low-key atmosphere where it is easy to carry on a conversation. If you hatch dinner plans at the end of the evening, the city’s world-class dining options are close by, or, you can catch an airport shuttle from the hotel lobby if need to depart early.

Enjoy Aspen
Of course, it would be a shame to cut your conference experience short, between the intriguing Friday sessions and the pleasures of September in the Rockies. We can’t promise good weather, but, most years, the days have sparkled with sunshine and fall colors and the nights have been crisp and clear.

Aspen Meadows Resort is now sold out, but you can still stroll the grounds. The city is close enough that you could park your car at your hotel and walk off the delicious meals—included in your registration fee—on your way to and from the conference.

If you need one more reason to attend the Rocky Mountain Utility Efficiency Exchange, the Building Performance Institute You are leaving WAPA.gov. awards continuing education units (CEUs) for many of the sessions. Download the instructions to find out how to verify your attendance.

White paper, training explore evolution of demand response

Utilities have long used demand response to deal with high wholesale electricity prices or generation shortfall. What was once accomplished with phone calls to large industrial customers or one-way controls on aggregated residential loads is now done in near-real time with sophisticated two-way communication. Yet, despite the fact that this strategy has become an integral part of grid operations in the U.S., there has been no agreement on a definition of demand response.

The Peak Load Management Association You are leaving WAPA.gov. (PLMA) set out last year to develop a consistent definition for demand response to use across its three training courses on the topic. A demand response dialogue that included several experts in the field took place in September 2016 and was recorded and archived on the PLMA website. At the 2016 PLMA conference later that year, the discussion continued with a panel presentation, Defining the Evolution of Demand Response: From 1.0 to 3.0 and Beyond.

Demand response evolution

Three epochs
The white paper from these discussions breaks down demand response into three periods beginning with the first interruptible tariffs for large commercial and industrial customers. Demand response was primarily used to provide energy (MWh) and capacity (MW) during periods of high wholesale prices, shortfall of generation or transmission capacity or unexpected emergency grid-operating situations. Utility staff contacted a commercial customer, usually a day or hours ahead of a forecasted event, to manually change power consumption onsite. Also, residential customers voluntarily allowed utilities to install load-control devices to cycle their water heaters and air conditioners. Verification usually came from the utility meter which was read on its regular cycle.

Current demand response strategies provide more precise energy and capacity to support the wholesale marketplace, along with sophisticated, near-instantaneous ancillary services such as non-spinning and spinning reserves and frequency and voltage support. Measurement and verification occur in almost real-time measurements (either utility or non-utility) and often serve as confirmation of customer performance during demand response events. Two-way communication also allows for greater customer feedback and engagement.

Demand response is evolving to be a component of broader distributed energy resources both behind and in front of the meter. The service benefits demand response offers in this capacity, both to the grid operator and to the customer, include volt/var control, renewable energy integration and localized distribution system congestion management. The future of demand response may move away from traditional utility control to automatic, pre-programmed triggers based on price thresholds.

Learn more
Two upcoming courses expand on PLMA’s demand response white paper to provide utility and regulatory staff and industry trade allies with a greater understanding of the evolution of demand response. Join subject matter experts from PLMA member organizations in Portland, Oregon, Sept. 26 or in San Francisco, California, Oct. 25.

Presentations will cover current technology and market conditions, utility case studies and more. Demand response will be compared to other load management strategies, and participants will discuss how to design a load management portfolio that serves your utility’s needs.

The training is open to all industry stakeholders, with significantly discounted rates to PLMA member organization staff.

The free event was held at WAPA’s Electric Power Training Center in Golden, Colorado, and drew strong attendance from every type of utility, especially in the West. As the workshop title stated, the agenda focused on the logistical aspects of building a community solar project and explored ways to make projects more successful. Speakers and participants discussed best practices for analyzing solar development opportunities, writing requests for proposals, engaging internal and external stakeholders, working with contractors and vendors and designing rates.

Customers share experience
Several WAPA customers were on hand to share their experiences with developing their own projects. Luis Reyes of Kit Carson Electric Cooperative You are leaving WAPA.gov. sat on a panel that focused on improving the procurement process. The Taos, New Mexico, utility launched its first community solar project in 2012 and has an ambitious initiative to install 35 megawatts of photovoltaics this year.

Participants throw ideas against the wall to see what sticks during table-top sessions on program design, procurement, rate design and marketing.

A panel on pricing challenges included John Phelan from Fort Collins Utilities You are leaving WAPA.gov. in northern Colorado. As a pioneer with Rocky Mountain Institute in clean energy and sustainability solutions, the city of Fort Collins has discovered that success brings a new set of challenges. For example, the utility is wrestling with how to design a rate that accommodates both a legacy community solar garden and a new array for qualified low-income customers.

Poudre Valley Rural Electric Cooperative You are leaving WAPA.gov. is currently developing a 6,000-panel community solar project with carve-outs for local nonprofit organizations and another for income-qualified customers. Making community solar available to customers who need the most help with utility bills was another topic that received a lot of attention. Utilities are experimenting with different business models for low-income projects, but most agree on the potential benefits: freeing up more money for other needs, bringing more certainty to monthly bills and raising energy awareness in a hard-to-reach group.

Attendees were all at different points on the learning curve with community solar. Representatives from the City of Fort Collins Utilities, Kit Carson Electric Cooperative and the city of Lamar, Colorado, shared their experiences during the free workshop.

SEPA report offers guidance on planning for distributed energy resources

As tempting as it may be for utilities to ignore the growth of distributed energy resources (DER), they must plan for integration of this form of generation. To help power providers develop a strategy to accommodate increasing DER penetration, Smart Electric Power Alliance You are leaving WAPA.gov. (SEPA) has published a two-volume report, Beyond the Meter: Planning the Distributed Energy Future.

Volume I: Emerging electric utility distribution planning practices for distributed energy resourcesThe utility industry is changing and many of the changes are being driven by consumers seeking new energy choices, technology advances leading to lower costs and better performance and new policies. Both utilities and their customers will have to work together to ensure grid reliability as distributed energy resource (DER) penetration increases. Engineering consultants Black and Veatch You are leaving WAPA.gov. collaborated with SEPA to provide a new strategy to become a proactive distribution planning utility.

Volume I: Emerging electric utility distribution planning practices for distributed energy resources outlines why traditional distribution system planning framework does not meet the needs of today’s grid. Five investor-owned and public power utilities shared their drive, progress and challenges when planning and proactively integrating distributed energy resources within their distribution system. The report covers:

  • Practical framework for distribution planning utilities
  • Insight from sector leaders on challenges and successes
  • Tools to better understand customer needs

Volume II: A case study of integrated DER planning by Sacramento Municipal Utility District Volume II: A case study of integrated DER planning by Sacramento Municipal Utility District details how SMUD used the findings of Volume I to forecast DER growth and plan for distribution challenges. Through the lens of SMUD, the report looks at the broader scenarios the electric utility industry can expect to encounter. The report covers:

  • Results of the new utility planning strategies
  • Risks and opportunities of new DER systems
  • More on the new distribution system planning framework

Beyond the Meter is free to download for both SEPA members and non-members.

CIPCO builds Iowa’s largest utility-scale solar project

In Iowa, where renewable energy is often synonymous with wind, one generation-and-transmission (G&T) cooperative is making a big investment in utility-scale solar generation. Over the last year, Central Iowa Power Cooperative You are leaving WAPA.gov. (CIPCO) built the state’s largest photovoltaic (PV) project across five sites in its service delivery territory.

The member cooperatives involved in the project are Clarke Electric Cooperative, You are leaving WAPA.gov.Consumers Energy, You are leaving WAPA.gov. Eastern Iowa Light & Power Cooperative, You are leaving WAPA.gov. East-Central Iowa REC You are leaving WAPA.gov. and Pella Cooperative Electric. You are leaving WAPA.gov. The 5.5-megawatt (MW) project will provide electricity to all CIPCO members of all income levels. “It is our mission as a cooperative to support all our members equally,” noted Communications and Public Affairs Manager Kerry Koonce. “Choosing the utility-scale model for the project rather than community solar accomplishes that.”

Becoming solar leader
In late 2015, CIPCO issued a request for proposals (RFP) for the development of the first of what is intended to be a two-phase utility-scale solar project.

Several of CIPCO’s 13 members showed interest in hosting a site. Then followed the hard work of determining which sites would be appropriate. “Some potential sites didn’t have sufficient resources, others had leasing issues,” recalled Koonce. “It is so important to make sure to get the correct layout, especially with a first-time project.”

CIPCO had help from the National Renewables Cooperative You are leaving WAPA.gov. (NRCO), a trade group formed by cooperatives to facilitate the development and deployment of renewable energy resources. NRCO managed the RFP process and supplied engineering expertise for the project. CIPCO has used NRCO resources in the past to review wind-purchase contracts as well.

To install the arrays, CIPCO selected Azimuth Energy LLC You are leaving WAPA.gov. of St. Louis, Missouri, an engineering, construction and development-support service company for renewable energy and energy efficient projects. The design of the ground-mounted arrays included features like fixed-axis racking and transformerless string inverters to reduce installation cost, improve performance and simplify maintenance. The projects were completed on schedule by the end of 2016.

Sun keeps rising
The new solar generation is part of a portfolio that includes 199 MW of wind power, 14 MW of WAPA hydropower and 1.6 MW of waste-to-energy generation. In all, CIPCO gets nearly 60 percent of its power supply from low-carbon resources. Koonce observed that clean energy has always been important to CIPCO’s members and with the decline in solar panel prices, the time was right to add solar to the mix.

According to Koonce, the solar site will eventually pay for itself in the energy it produces, although the exact payback period is not known. The $9 million cost of all five solar sites, spread over 20 years to take advantage of some federal solar tax credits, is significantly less than the cost of building a new coal-fired plant, she added.

CIPCO’s overall resource plan focuses on natural gas, wind and more solar, with a second phase of solar development planned for this year. Battery storage is not part of the conversation at this point, Koonce noted, because the cost of storage systems is still very high compared to CIPCO’s stable rates. For now, “Our members won’t be seeing an increase due to adding solar,” Koonce says. “The resource is very cost effective for us.”

But members can be sure that CIPCO will be watching battery storage and other new technologies, as the G&T continues to build its diverse, affordable and environmentally friendly power supply.

WAPA’s low rates save Weaverville

By Philip Reed, WAPA technical writer

Trinity Public Utilities District You are leaving WAPA.gov. (TPUD) is a small utility with a workforce consisting of only 22 employees, located in Weaverville, California. It was founded in 1981 and has recently become a valued WAPA customer.

The town of Weaverville had some of California's highest electrical rates until it became a WAPA customer.

The town of Weaverville had some of California’s highest electrical rates until it became a WAPA customer.

“Prior to that, Weaverville was being served by a small investor-owned utility,” said TPUD General Manager Paul Hauser. “They wanted to sell their distribution lines and get out of Trinity County. The community came together to raise and borrow the money necessary to purchase the distribution assets themselves.”

Dick Morris was a founding member of TPUD, and is still on the board today.

“We were motivated to take over the system and partner with WAPA when the previous utility made it clear that they were contemplating the sale of this system, along with their holdings in other small communities,” said Morris. “This was an opportunity. The previous utility had been bombarded by high-bill complaints from customers. City of Redding customers were paying around $21.00 for 1,000 kilowatt-hours (kWh), while in Weaverville we were paying $72.00 for the same usage. This was our chance to change that.”

Hauser says that joining WAPA saved Weaverville.

“The rates we were paying were far too high, and the local lumber mill was in serious danger of closing because of high electricity prices,” explained Hauser. “Weaverville had some of the highest rates in the state at the time. Now that we work with WAPA, we actually have some of the lowest rates, but that wasn’t the case then. It was difficult for the mill to stay afloat.”

The Trinity River Lumber Company is the municipal utility's biggest load and the heart of the local economy.

The Trinity River Lumber Company is the municipal utility’s biggest load and the heart of the local economy.

The lumber mill is the largest private employer in the area with around 130 employees, and it’s critical to the overall well-being of both Weaverville and Trinity County. It is the only lumber mill still operating in the county, and it represents more than 10 percent of TPUD’s load.

“We pleaded with the mill owners not to scrap out the plant, but to keep it intact for two years while we sought a new owner to take it over,” said Morris. “If we were to succeed in purchasing the distribution assets and start working with WAPA allocation, we pledged to provide the new owners a substantial reduction in their cost of electricity.”

TPUD was able to find a new owner for the mill: Trinity River Lumber Company. They worked with Sierra Nevada staff members to receive a preference power allocation, a process that was completed in 1982.

“The importance of the mill to this community cannot be overstated,” said Hauser. “Had the mill failed, the economy of the entire county would have collapsed. We would have lost those jobs and it would have become uneconomical to perform the forest thinning that allows forest fires to be managed in a way that minimizes impact to the people of Trinity County. Losing the mill would have crushed us.”

Fortunately, TPUD was successful in purchasing the distribution assets and partnering with WAPA. As a result, the mill, the economy, and those 130 jobs were saved, preserving the economic health of the area.

“Thanks to the service we started getting from WAPA, the new owners were able to operate the mill more cost effectively,” Morris said. “The previous utility required the mill to pay around 10 cents per kWh. With WAPA, we were able to reduce the cost to three cents.”

Thirty-five years later the mill, once in danger of shutting down and taking its jobs with it, still operates.

“Access to WAPA’s low-cost hydropower allowed TPUD to offer rates low enough for the mill to stay in business,” Hauser said. “The benefit of partnering with WAPA was that direct.”

TPUD is now also able to offer customers increased reliability, as WAPA line crews provide assistance during major storms and outages. “That’s something we couldn’t do on our own,” said Hauser.

“I am pleased that WAPA was able to work out such a synergistic relationship with the owner- shareholders of TPUD,” said Senior Vice President and Sierra Nevada Regional Manager Subhash Paluru. “I’m also pleased that through the years WAPA and TPUD have continued to be valuable and reliable partners.”

“WAPA really is a fantastic partner,” Hauser concluded. “Its employees are very helpful to a small utility like us. We simply could not operate without the partnership that we have with WAPA.”

Still time to register for free community solar workshop

June 7-8
Golden, Colorado

Community Solar Procurements, Programs and Pricing, a free regional workshop for utilities, is filling up fast but there is still room for a few more attendees.

Community solar projects are a successful business model where multiple customers share in a large solar array, paid for through individual utility bills. It has seen such rapid growth across the country that it has become almost commonplace. Despite that fact, utilities are still learning about every aspect of this resource. It is important to get your project off on the right foot or correct missteps before they mushroom.

WAPA’s Renewable Resources Program has teamed up with the Community Solar Value Program You are leaving WAPA.gov. (CSVP) to make it affordable for power providers to share best practices in developing this type of generation. There is no registration fee for this event; attendees need only pay for their travel to Golden, Colorado. “Helping our preference utility customers learn about community solar and other renewable technologies, as well as tools and resources for smooth integration are a core part of WAPA’s Renewable Resource Program,” explained Randy Manion, WAPA Renewable Resources program manager.

The agenda You are leaving WAPA.gov. draws from an investigation conducted by CSVP into utilities’ best practices and innovations in community solar. From design to procurement to marketing, participants will hear from expert speakers and utility peers who will share their experiences. Presentations by WAPA customers include Kit Carson Electric Cooperative You are leaving WAPA.gov. on requests for proposals and Sacramento Municipal Utility District You are leaving WAPA.gov. on integrating community solar with distributed systems.

WAPA’s Electric Power Training Center (EPTC) in Golden, Colorado, is hosting the event. The workshop will begin at 3:00 p.m. on Wednesday, June 7, with a “lightning round” of community solar best-practice presentations and a tour of EPTC’s grid simulator, followed by a networking reception. On Thursday, June 8, the workshop will convene from 8 a.m. to 5 p.m., with breaks and a networking lunch provided by Extensible Energy LLC included.

Registration is free, but required. Participants only cover travel and hotel costs and incidentals.

Don’t miss this opportunity to explore this promising strategy for incorporating solar power into your resource mix.
