AgriSolar News Roundup: Agrisolar Refrigeration, Pennsylvania Agrisolar, New Zealand Agrisolar Development  

African Company Provides Agrisolar Refrigeration 

“A company called AkoFresh is providing solar-powered refrigerated storage that it says extends the shelf life of perishable crops from about 5 days to 21 days. This will boost seasonal income for farmers by more than $10 million, as well as reduce greenhouse gas emissions by 15%. Farmers can rent a space in the cold store for a daily fee of $0.30 per 20-kilogram crate of produce or take up a weekly subscription. They can also pay for the cold storage with crops instead of cash.” – World Economic Forum 

Research Being Conducted at Pennsylvania Agrisolar Site 

“In recent years, the environmental management of solar farms has become an exciting area of academic research, to assess how different practices affect the productivity of solar and agricultural enterprises and the land on which they operate. Two studies seeking to answer research questions around these topics are currently underway at Lightsource bp’s Nittany 1, 2 and 3 solar projects in Pennsylvania.   

All three sites were designed and are being actively managed to boost biodiversity and support pollinator populations, in addition to generating clean energy for Penn State and their students. Lightsource bp seeded the sites with a mix specifically formulated by the American Solar Grazing Association (ASGA), in partnership with Ernst Conservation Seeds and Pollinator Service. The seed mix, aptly named ‘Fuzz and Buzz,’ was designed to support pollinator species at solar sites, in addition to flocks of sheep. At Nittany 1, more than 700 sheep are managing vegetation through rotational grazing, an example of agrivoltaics, or co-located solar and agriculture.” – Lightsourcebp 

 New Zealand Solar Farm Will Host Sheep 

“Harmony Energy New Zealand has been granted approval to develop a solar farm in the Waikato which will generate electricity to power 30,000 homes as sheep graze underneath. The Environmental Protection Authority (EPA) has approved Harmony’s proposal for approximately 330,000 solar panels to be installed on 182 hectares of a 260-hectare site at Te Aroha West. The land will remain in the ownership of Tauhei Farms Limited, with livestock grazing continuing with sheep, rather than the current dairy herd.” –https://www.stuff.co.nz/business/300693453/hauraki-solar-farm-that-could-power-30000-homes-gets-green-light Power Technology 

ASGA + AgriSolar Clearinghouse September Teatime: Vegetation Management at Operating Solar Sites with Keanen Ryan and Lexie Hain, Lightsource bp

What are asset managers looking for when they evaluate proposals from solar graziers? What kinds of concerns do asset managers have about grazing that need to be resolved to get to the contract stage?

Keanen Ryan and Lexie Hain from Lightsource bp joined us for a wonderful conversation that answered these questions from the solar operations perspective. Keanen and Lexie also discussed what they’re looking for from graziers in terms of services and experience in order to meet the economic and sustainability standards of Lightsource bp.

AgriSolar News Roundup: Vermont Agrisolar Study, Agrisolar Research in Maine, Wisconsin Dairy Farm Goes Agrisolar 

Vermont Agrisolar Study Shows that Saffron Grows Well Under Solar Panels 

“A study released earlier this year summarized the results of a three-year experiment conducted by the University of Vermont. The research concluded that, given the right soil conditions, saffron grows well in the aisles and at the edges of a solar array, which could boost bottom lines for farmers by allowing them to draw dual revenue streams from a single section of land. 

‘We could see diversified vegetable growers growing lots of spinach and kale, but they weren’t making any money at it because everybody was growing the same thing. We felt saffron offered an opportunity for these growers to add a high-value crop,’ said Margaret Skinner, a researcher at the University of Vermont.  

According to the study, “when soil conditions are suitable, saffron can be grown successfully within a conventional tilted solar array, generating between $7,500 – 130,000 per acre.” – Energy News Network 

University of Maine Studies Agrisolar Blueberry Yield  

“A farmer in Maine has teamed up with a solar developer and university researchers to find out how his (blue)berries fare when partially shaded by solar panels. The University of Maine is studying this example of dual-use agrivoltaics.  

The solar installation was developed by the Boston-based solar developer BlueWave, and it is owned by the company Navisun, which makes lease payments to the landowner. Sweetland tends, harvests, and sells the blueberries, and shares profits with the landowner. 

The university (Maine) received grant funding to continue the study for three more years from the Northeast Sustainable Agriculture Research Education program, which is supported by the U.S. Department of Agriculture’s National Institute of Food and Agriculture. The research team will compare the blueberry yield among the plants fully shaded by panels, plants partially shaded by panels and plants with full sun. The panels are 8 feet tall in rows spaced 8 feet apart.” – Canary Media 

 Wisconsin Dairy Farmer Finds Financial Safety in Agrisolar  

“Brent Sinkula, president of the Manitowoc County Farm Bureau, understands the challenges Wisconsin dairies are facing. The changing dairy market has made it more difficult for small and mid-sized farms to continue. Without plans to expand the dairy, Sinkula was looking for another way to maintain the family farm. In 2018, an energy company approached him interested in renting 500 acres, about a third of his land, to install solar energy panels.  

For Sinkula, hosting solar panels on his land provides a financial safety net for the farm. He’s not the only farmer to make similar arrangements. Farmers have what solar energy companies need: land. Across the state, partnerships between dairy farms and energy companies are increasing, changing the landscape and providing farmers extra revenue in a sometimes unpredictable market.” – WPR 

AgriSolar News Roundup: Solar Sheep, Five C’s of Agrivoltaics, Illinois Team Developing AgriSolar Game  

The Solar Industry’s Mower of Choice: Sheep 

“The panels blanket nearly 1,500 acres of a solar farm in Deport, a town near the Oklahoma border. Ely Valdez, the boss, makes sure prairie grasses don’t block sunshine from the panels. His sheep do most of the work. Sheep, the surprise workhorse of renewable energy, are generating several million dollars in annual revenue tidying up solar farms nationwide. 

‘It’s changing all of our lives,’ said Mr. Valdez. He expects the flocks he oversees to soon generate several hundred thousand dollars in annual revenue. The number of acres of solar fields employing sheep in the U.S. has grown to tens of thousands from 5,000 in 2018, according to estimates by people in the business. Flock owners charge as much as $500 an acre a year. 

The solar industry auditioned several methods for the job, but requirements weeded out expected contenders. Power mowers, which can’t maneuver easily enough under panels to avoid the risk of damaging equipment, are of limited use. “Sheep truly are the appropriate technology for this,” said Michael Baute, vice president of regenerative energy and carbon removal at solar developer Silicon Ranch Corp., based in Nashville, Tenn.” – The Wall Street Journal 

The “Five C’s” of Agrivoltaics 

“These are among the most important findings of an ongoing agrivoltaics research project called Innovative Solar Practices Integrated with Rural Economies and Ecosystems (InSPIRE). Led by the National Renewable Energy Laboratory (NREL) and funded by the U.S. Department of Energy’s Solar Energy Technologies Office, InSPIRE has just completed its second, three-year phase of research into the synergies between solar energy and agriculture.  

In its first phase, InSPIRE tried to quantify the benefits of agrivoltaics and record some early best practices in the emerging field. The project adopts a big-tent approach to agrivoltaics, welcoming any dual use of solar-occupied land that provides ecological or agricultural benefits. That could mean grazing cattle or sheep, growing crops, cultivating pollinator-friendly native plants, or providing ecosystem services and restoring degraded soil.  

The InSPIRE project found five central elements that lead to agrivoltaics success, summarized as ‘the five C’s’: 

  • Climate, Soil, and Environmental Conditions — The ambient conditions of a location must be appropriate for both solar generation and the desired crops or ground cover.  
  • Configurations, Solar Technologies, and Designs — The choice of solar technology, the site layout, and other infrastructure can affect everything from how much light reaches the solar panels to whether a tractor, if needed, can drive under the panels. “This infrastructure will be in the ground for the next 25 years, so you need to get it right for your planned use. It will determine whether the project succeeds,” said James McCall, an NREL researcher working on InSPIRE.  
  • Crop Selection and Cultivation Methods, Seed and Vegetation Designs, and Management Approaches— Agrivoltaic projects should select crops or ground covers that will thrive under panels in their local climate and that are profitable in local markets.  
  • Compatibility and Flexibility — Agrivoltaics should be designed to accommodate the competing needs of solar owners, solar operators, and farmers or landowners to allow for efficient agricultural activities.  
  • Collaboration and Partnerships — For any project to succeed, communication and understanding between groups is crucial.” –  NREL 
  •  

Illinois University Team Developing Interactive Agrisolar Game  

“A team led by University of Illinois, Urbana-Champaign researchers is developing an educational game it hopes can inspire future farmers to think differently about solar power. The app aims to teach kids the emerging concept of agrivoltaics, in which agricultural production is combined with solar photovoltaics. The game will be backed by science from the growing niche of research looking into how solar panel placement affects the growth of various crops.  

‘Dual-use land is really a great idea, intuitively, so why not build an app that lets kids explore these really interesting ideas while they’re playing a game?’ said H. Chad Lane, associate chair for educational psychology at the University of Illinois, Urbana-Champaign. 

Think Farmville, but instead of gamifying every aspect of running a farm, it will focus on the interaction between crops and solar panels. Researchers are discovering that several plant types can perform better when partially shaded by panels; for others, the reduced production can be offset by extra revenue from selling solar power to the electric grid.” – Energy News Network 

Community AgriSolar: Merging Agrisolar and Community Solar 

Merging community solar and agrisolar could aid the Department of Energy’s (DOE) goal of saving $1 billion in energy costs through community solar by 2025. Not only would merging community solar and agrisolar help DOE reach that goal, but would also provide other opportunities and benefits such as the regeneration of soil on solar sites, reducing fuel-operated maintenance demands, and increasing the likelihood of future solar development(s). 

What is community solar? 

Community solar could be an ideal method for low-income households who might be looking to use solar energy and use Low-Income Home Energy Assistance Program (LIHEAP) assistance to pay for their energy bills. LIHEAP funds cannot be used for things like up-front installation costs of typical solar participation methods (non-community solar) or the household ultimately owning the solar equipment. Community solar participation eliminates these issues due to the solar farm and panels not being developed, owned or operated by the LIHEAP recipient.  

LIHEAP Participants Would Lead to More Energy Savings 

Community solar often includes what is known as subscription-based community solar programs (SBCSPs), where a household “rents” solar panels and uses solar energy without the associated conditions and costs of installing solar panels, operating them, or owning them. These conditions of using solar energy typically would not qualify a low-income household to use LIHEAP funds for solar fuel. However, SBCSPs could provide a way for low-income households to be able to use LIHEAP benefit payments for solar fuel through subscription-based community solar programs because the household would not ultimately own the equipment or have to pay for its installation or maintenance costs. 

If LIHEAP participants are eligible for SBCSPs, then more people can participate in saving energy by using community agrisolar, which ultimately assists in the identified goal of the Department of Energy (DOE) in reaching $1 billion in energy savings through community solar by 2025. 

Why merge agrisolar with community solar? 

Community solar has been identified by DOE as a method of reaching energy savings goals by 2025, which includes saving $1 billion in energy costs. Merging agrisolar with community solar developments would not only aid in significant energy savings but would also make future solar developments more likely to be approved—expanding energy savings even further. 

Agrisolar operations like the Cabriejo Ranch in Missouri has shown that agrisolar provides a variety of energy saving methods as well as regenerating the land used by solar farms. The ranch uses Dorper sheep to manage the vegetation on solar operations, which drastically reduces the use of fuel-operated maintenance equipment typically used to manage vegetation. The sheep not only reduce these energy costs, but dramatically increase the health of the soil .  

The likelihood of a solar farm being approved for development is higher when Agrisolar is incorporated into the operations. This was seen in the Garnet Mesa project that was denied due to concerns about losing valuable farmland to the solar-farm development. The project was approved after changes were made to include 1,000 grazing sheep on the solar farm. 

The Possibilities of Merging Agrisolar and Community Solar   

 More participants saving more energy would be a win-win for reaching energy-and-cost savings goals.  

Not only do energy savings goals have a higher likelihood of being achieved through merging community solar and agrisolar, but other benefits of using agrisolar would also be made possible, such as regenerating soil health through grazing practices and supporting  job creations in local communities such as grazing management and farm operations jobs created in Missouri. These benefits of using agrisolar in solar development increases the likelihood of future solar developments by proving the land can be effectively utilized while occupied by solar equipment and operations.  

Follow the Sun Tour: Massachusetts

By Stacie Peterson, PhD

The farmlands of Massachusetts are cherished landscapes, steeped in cultural significance and family connections. Coming from the drought-ridden western United States, I was struck first by the lack of irrigation pivots and the lushness of the landscape, even after a heatwave uncommon to the area. I then scanned the rolling hills for solar, excited to see the Massachusetts SMART program in action. I wasn’t disappointed. The solar array at the University of Massachusetts South Deerfield Research Farm presented a picture-perfect site to start our tour.

Follow the Sun Tour Attendees at the UMass South Deerfield Agrivoltaic Research Site

The tour attendees matched my enthusiasm by showing up early and leaning over the fence to better view the solar farm. We were welcomed by Dr. Dwayne Berger from University of Massachusetts, who gave a presentation on the DOE SETO-funded research at the farm. This project involves the study of crop productivity on crops planted under a solar array installed by Hyperion Solar.

Next, Gerry Palano gave a presentation on Massachusetts Agricultural Solar Tariff Generation Units and their relation to agrivoltaics in the Massachusetts Solar Massachusetts Renewable Target (SMART) Program, which provides financial incentives for solar projects. From there, we went out to the farm, where Jake Marley from Hyperion Systems described the solar array design, and Dr. Stephen Herbert discussed the current crops and research at the array.After a quick lunch, we boarded the bus and started our mobile conference of speakers. Dr. Zach Goff-Eldredge kicked off the bus tour with a discussion of DOE SETO’s programs and their support of agrivoltaics. 

Dr. Zach Goff-Eldredge Manager of DOE SETO Agrivoltaic Programs

AgriSolar Clearinghouse consultant Alexis Pascaris of AgriSolar Consulting then gave an inspiring talk, envisioning the future of agrisolar from the perspective of farmers, landowners, solar developers, and community members.    

Candace Rossi from the New York State Energy Research and Development Authority (NYSERDA) then spoke to the group about the impactful programs in New York State and their relevance to AgriSolar around the country. We arrived at Nate Tassinari’s family farm in Monson with the sun high overhead. Nate welcomed the group to his home and talked about the Million Little Sunbeams project he developed  to preserve his family’s farmlands. The farm includes co-located solar and hay, an apiary, and an orchard. As shown in the photo, the 250-kW solar array, installed by Sunbug Solar, has an elevated racking system that accommodates haying equipment. The panels are bifacial, and Nate described the increased solar energy production from the bifacial panels as a result of both hay and snow reflections.

The Million Little Sunbeams project created a financial pathway for Nate and his family to own the land and the solar system; this project does not involve a lease to a solar developer.  Nate graciously fielded questions about his process and Gerry Palano fielded questions about the SMART funding piece of the project. Nick d’Arbeloff from Sunbug Solar fielded technical questions about the solar array and site design.

We then travelled to a late-breaking and welcome addition to our tour with Dan Finnegan from Solar Shepherd in Brookfield. On the way, Lexie Hain, former president of the American Solar Grazing Association and current Director of Agrivoltaics and Land Management at Lightsource BP, gave the group a background on solar grazing.When we arrived at Solar Shepherd, Dan’s assistant, Reggie the Wonder Dog, herded the sheep toward the gate to greet us and then herded them to the solar array, so we could witness solar grazing first- hand. Dan described his solar grazing work in Massachusetts and talked with tour members about the practicalities of solar grazing, such as sheep transportation, water needs, leasing, and solar grazing contracts.

Solar Grazing with Solar Shepherd

After Solar Shepherd, we boarded the bus to travel to our last agrisolar site: Grafton Solar at Knowlton Farms. On the way, we heard from AgriSolar Clearinghouse stakeholder Ethan Winter from American Farmland Trust (AFT) about AFT work on smart solar siting, agrivoltaics, and at  

Grafton Solar at Knowlton Farms provided the tour group with the opportunity to see a large-scale agrisolar site. The 334-acre hay farm includes solar developed in several phases on 75 acres. In addition to Paul Knowlton, fourth-generation family owner of Knowlton Farms, the project includes a slew of agrivoltaic advocates, solar developers, researchers, and the State of Massachusetts. 

The agrisolar portion of Knowlton Farms, known as Grafton Solar, is owned and operated by AES Corporation, which pays Knowlton Farms lease payments and a stipend for the cost of farming. The Massachusetts SMART program provided incentives for the project and the University of Massachusetts and American Farmland Trust study the impact of the solar array on crop yields and soil conditions.

Paul Knowlton, at Grafton Solar at Knowlton Farms

Paul Knowlton talked with the group about his decision to enter into a lease agreement for solar at his farm, its positive financial impact to his family business, and his hopes that the project will help keep the farm in the family well into the future. Dr. Sam Glaze-Corcoran from University of Massachusetts Amherst described soil and crop studies and, along with Gerry Palano and Swayne Berger, fielded questions about how those studies inform University of Massachusetts recommendations to the SMART program.  Ian Ward, of Solar Agricultural Services, discussed the site design, plantings, and the potential for this project to serve as an example for other farmers in New England. Ian’s advocacy centers on keeping farmlands in the hands of farmers and in preserving farmlands for the future. Julie Fine, AFT’s Climate and agriculture specialist then led the group crop co-location potion of the site and described her work assessing impacts to crops, soil, and ecosystem services.

The group then boarded the bus for the ride back to Amherst, full of ideas, connections, and energy. Charles Gould, from Michigan State University Extension, talked about his impressions of the day, his work in agrivoltaics, and his thoughts on the future. Judy Anderson, of Community Consultants, led the tour group in a roundtable discussion of the tour, ways to engage policy makers, and how to move forward in a way that supports agrisolar throughout the country. 

Million Little Sunbeams AgriSolar Site

Tours like this are months in the making. From scouting potential sites and tour routes to meetings with farms, solar developers, local governments, and potential speakers. They have the complexity and logistics of a mobile conference. This tour couldn’t have happened without the help of Alexis Pascaris of AgriSolar Consulting and Jake Marley of Hyperion Systems. They were at the heart of this tour and worked with me for months as we planned, connected, and revised. They were flexible with last-minute changes, and I deeply appreciate their contributions to the tour.

I’d like to thank University of Massachusetts for hosting the event at the South Deerfield farm and for allowing us to gather in their meeting space. Thank you, too, to Nate Tassinari for hosting us at his home in Monson; I appreciate his flexibility with last-minute schedule changes and his warm and insightful tour of his farm. Dan Finnegan and Reggie the Wonder Dog deserve a huge round of applause for treating the group to a demonstration of solar grazing in Brookfield. And thank you to Paul Knowlton, The AES Corporation, Ian Ward, Glaze-Corcoran, Julie Fine, Dwayne Berger, and Gerry Palano for the excellent tour of Knowlton Farms. It is a model agrisolar site with impressive research and support.

I’d like to thank the Solar Energy Technology Office of the U.S. Department of Energy for funding this work and Dr. Zach Goff-Eldredge for attending the tour. His support of agrivoltaics is evident around the country and the work the SETO team is doing in this space is creating a pathway for co-located agriculture and solar that works for farmers, community members, and solar developers.

NCAT’s Sustainable Energy and Sustainable Agriculture Teams Joining Forces for AgriSolar

I’d like to thank Danielle Miska, Andy Pressman, and Chris Lent from NCAT for their work on this project and for the AgriSolar Clearinghouse team at NCAT, around the country who cheered us on. I’d also like to thank Nicole Karr, our photographer. It is her beautiful photos throughout this blog. Finally, I’d like to express my gratitude to the tour attendees. The Follow the Sun Tour is one way the AgriSolar Clearinghouse works to build community, relationships, and trusted, practical information and I thank you all for joining us. It was a marathon tour of presentations, site tours, bus speakers, roundtables, networking, honey sticks, and fun. Your energy and enthusiasm are inspiring, and I can’t wait to see you on the road again.

AgriSolar News Roundup: Colorado Solar Grazing, Delaware Agrisolar, Plattsburgh Solar Grazing 

1,000 Sheep Will Graze Colorado Solar Farm  

“Solar developer Guzman Energy achieved regulatory approval from the Delta County Board of Commissioners for a limited use permit to install and operate an 80 MW project on land in Southern Delta County, Colorado. The site that will house the array is currently irrigated and utilized for grazing, and will continue to be used in that manner, said Guzman Energy. About 1,000 sheep will remain on the site to manage vegetation and graze on native plants.” – PV Magazine 

Delaware Solar Farm Grows Perennials  

“There’s nothing particularly remarkable about a farm growing common decorative flowers, but the Remelts aren’t growing them in the traditional way, which would be in a greenhouse or outdoors at a nursery. Instead, they’re raising mums in a row between two banks of solar panels—making agricultural use of idle land that so many farmers who have reserved acreage for lucrative solar farms might have written off as unusable. 

Parker explained how he and his father, when considering how to use the land occupied by the solar panels, settled on planting mums. They needed a crop that wouldn’t interfere with the operation of the panels, a qualification the mums met. As a bonus, the perennial flower also tends to be hardier when grown outdoors.” – Rochester City Newspaper 

Sheep Grazing New Solar Farm in New York 

“The solar array sits on 23 acres with a strict grass height limit. ‘The main goal here is we don’t want the grass or any vegetation growing above the panels blocking sunlight, basically a loss of power,’ said the farm’s Josh Pierce. He says it would take a lot of effort to cut and trim all that vegetation. ‘Underneath the panels— the grass also grows up there— that’s the challenge of getting a mower in.’ 

Their 75 sheep live at the solar farm from May until October. Their job is to graze the grass and weeds to make sure the solar panels are clear to soak in the sun. ‘A lot of this is great forage. It’s a mix of orchard grass and alfalfa, which is like candy for them,’ Josh explained.” – WCAX 

Follow the Sun Tour Minnesota

By: Stacie Peterson

Minnesota is a leader in agrisolar, thanks to innovative policies, inspiring research, and a committed network of agrivoltaic and pollinator advocates. The Follow the Sun Tour had the opportunity to visit four of Minnesota’s AgriSolar sites on an action-packed summer day full of site visits, speakers, and a social networking event on August 4, 2022. 

We began the day by gathering at Connexus Energy’s Headquarters. After group introductions, we boarded a bus, which served as a mobile conference room, and heard from our first speaker, Heidi Kolbeck-Urlacher from Center for Rural Affairs. Heidi spoke about the Center’s work in agrivoltaics and their work as a partner of the AgriSolar Clearinghouse.

Heidi Kokbeck-Urlacher Speaking on the Follow the Sun Bus

Our first tour stop was the Enel North America Lake Pulaski site. This site combines solar, pollinators, an apiary, and sheep grazing. Jesse Puckett and Eric Bjorklund from Enel North America gave a safety briefing, an overview of the site, and described Enel’s agrisolar work around the world.

The chefs cooked the food with solar power, including a solar generator and a solar-powered electric truck, powered by the Connexus Headquarters solar array. For drinks, solar-grown honey sweetened the lemonade and Rob Davis’s signature cocktail, Everything but the Stinger, featuring Clif Family’s solar-grown honey ginger syrup. Invictus Brewing treated the group to their 1.7 Million Megawatts British Summer Ale, made with solar-grown honey.

The sampler was an excellent networking opportunity and chance to discuss what we learned and witnessed through the day. There was so much excitement about future projects and partnerships and plans. The hum of enthusiasm was palpable. 

Networking at the Follow the Sun Tour

While folks connected, we heard from Greg Ridderbush, Connexus Energy’s CEO, about their commitment to agrivoltaics and sustainable energy and the great work performed by the company. We then heard again from Jesse Puckett and from Rob Davis, and I wrapped up the day with a hearty toast to our AgriSolar Clearinghouse community.

As I milled around, I watched the AgriSolar network strengthen and expand. Folks made plans, dreamed up future events, talked about partnerships, exchanged business cards, and enjoyed each other’s company. As our stakeholder Lucy Stolzenberg said, the only way to make the event better would be to have another!

Solar Farm Gets Green Light After Including Agrisolar

Delta County, Colorado, commissioners have given approval to the Garnet Mesa solar farm to proceed with developing a 475-acre, 80-megawatt solar farming facility that was previously rejected due to concerns about losing farmland. After developers modified their plan by added 1,000 sheep to occupy the farm, commissioners voted to grant the land-use permit, satisfied that concerns about losing farmland had been resolved due to the conversion to agrisolar.  

“All negative comments were addressed by the applicant except for use of other desert lands for a solar energy facility. Those in favor of bringing a solar energy system to Delta mentioned helping the environment, additional tax revenue for the city, cheaper rates for customers and having a local energy source as reasons to support the proposal,” according to the Delta County Independent. 

“Interior fencing will be added to facilitate safe containment for the sheep and to prevent overgrazing. Sheep will also be provided with watering sites and other facilities necessary for safety and well-being, according to project plans presented during an open house,” said the article. 

“The two commissioners opposing the plan said they were concerned about the loss of agricultural land in the county. Guzman Energy has revised its Garnet Mesa project to ‘specifically address the agricultural and irrigation concerns raised by the community and commissioners,’ Amy Messenger, a company spokeswoman, said in an email,” according to The Colorado Sun.  

Garnet Mesa is expected to produce enough power for 18,000 homes each year and to create an estimated 350 to 400 employment opportunities, including sheep and farm management.
