Converse County is without doubt one of the most welcoming areas in Wyoming in relation to clear vitality. For roughly each 20 residents, there may be one wind turbine, the very best ratio within the state. At a latest County Commissioners assembly, it took one other step in diversifying its vitality infrastructure, signaling its intent to challenge its first photo voltaic farm allow to BrightNight.
The worldwide vitality firm has proposed to construct greater than 1 million photo voltaic panels, a battery storage facility and some miles of above-ground transmission strains on a 4,738 acres of personal land run by the Tillard ranching household close to Glenrock. The Dutchman Mission, as it’s known as, is notable neither for its era nor its storage capability however for the creatures moseying beneath its panels.
The bottom of every sun-tracking panel will probably be a number of toes off the bottom, permitting sufficient room for the Tillard’s sheep to proceed grazing. In a state whose ranching business predates its inclusion within the union, pairing photo voltaic era with livestock grazing or different agricultural practices, a method known as “agrivoltaics,” may forge an unlikely alliance between two industries — one historical; the opposite, excessive tech — that usually compete for assets.
On the conclusion of their February 6 listening to relating to the Dutchman undertaking, Converse County Commissioners directed the county legal professional to draft an order of approval, indicating they might seemingly grant the undertaking its allow later this month.
“BrightNight is proud to succeed in at the moment’s allowing milestone. Our undertaking is ideally-sited to ship precious capability to a rising area making ready for vital era retirements,” stated Maribeth Sawchuk, the corporate’s vp of communications, in an announcement to Inside Local weather Information. The corporate is concentrated on “utility-scale renewable energy options whereas additionally elevating the business customary for neighborhood engagement and assist.”
The Tillard household couldn’t be reached for remark.
Jim Willox, chairman of the board of Converse County Commissioners and one of many individuals answerable for reviewing BrightNight’s allow utility, remembered being excited to see the corporate proposing to make use of an agrivoltaic strategy to constructing photo voltaic.
“I believe the photo voltaic business has discovered that they don’t need to be simply naked floor beneath,” he stated. “I discover that very thrilling and a continuation of Wyoming’s view on a number of use.”
Willox has been a Converse County Commissioner for the final 18 years, throughout which he’s witnessed the rise, fall, and rise once more of fossil fuels within the county. When he first began his job, coal manufacturing was an enormous financial asset to the county. Now, “it’s zero,” he stated.
Whereas fossil fuels nonetheless play an vital position within the county’s economic system, and Converse County nonetheless takes an “all of those above” strategy to vitality improvement, “we additionally actually imagine renewables are a part of the vitality portfolio for the nation and customarily are welcoming to them,” Willox stated.
Economically, Willox seen the photo voltaic farm as supply of tax income for the county. “You’ll have gross sales tax that will probably be collected throughout development, then there will probably be a property tax worth enhance,” cash from BrightNight that can be utilized for faculties, hospitals, and different public assets within the county, he stated.
Nonetheless, renewables — very like oil, fuel, and coal — usually are not with out “some challenges and a few issues,” Willox stated.

A number of partnerships between farmers and scientists have proven that some crops react poorly to residing beneath the penumbra of a photo voltaic farm. Shade from the panels can generally lure an excessive amount of water close to the crops, and the presence of enormous photovoltaics could make it troublesome for farmers to conduct their harvest.
On the public briefing held in Douglas, Wyoming, on Tuesday, county residents gathered in a courthouse basement to listen to shows from BrightNight executives relating to the Dutchman photo voltaic farm’s allow utility. Afterwards, some county residents voiced issues relating to the photo voltaic farm’s entry to transmission strains, its impression on prairie canine migration patterns and the consequences of radiation on residents.
BrightNight should watch for its county and state permits earlier than figuring out its grid entry, stated Jess Melin, BrightNight’s govt vp of improvement. As with different close by vitality tasks going by the allowing and contracting phases, Melin stated as soon as BrightNight has “a allow and an influence contract, that’s the purpose after they say ‘OK, let’s really sit down on the desk and negotiate queue place,’” for delivering vitality to the grid.
Brandon Pollpeter, BrightNight’s director of improvement, known as prairie canine migration a “troublesome factor to handle,” and stated the corporate would coordinate with the Wyoming Recreation and Fish division to think about finest practices for responding to the rodents. He added that any high-voltage gear, which produces a small quantity of electromagnetic waves, has been sited removed from the neighborhood, and wouldn’t be an element to county residents.
“This county may be very educated on vitality and vitality era,” stated Pollpeter. “We’ve gotten some excellent suggestions.” Pollpeter added that BrightNight elevated the undertaking setback and moved its development entrance in response to native issues.

There may be proof that agrivoltaic photo voltaic farms are simply as efficient grazing areas as conventional open pastures, and that combining grazing with photo voltaic era will increase land productiveness by providing crops respite from the solar in sizzling, arid environments.
Within the spring of 2019 and 2020, Chad Higgins and a workforce of different researchers from Oregon State College tracked sheep grazing at an agrivoltaic photo voltaic farm in Oregon, measuring the animals’ progress, grazing habits and water consumption. They cut up two teams of sheep on the identical land; one which grazed close to the photo voltaic panels, and one other searching on open pastures. What they discovered led them to conclude that agrivoltaic photo voltaic farms could be an excellent setup for sheep ranchers.
“Within the early spring grazing time, which is when essentially the most intense grazing is and essentially the most progress is, we may put extra sheep on the agrivoltaic array than on the open pasture, and the sheep grew on the similar charges,” stated Higgins, an affiliate professor in Oregon State College’s division of organic and ecological engineering. “There was general extra manufacturing in that intense grazing interval due to the photo voltaic panels.”
The explanation why has to do with shade. “You may cut back warmth stress to crops by watering them extra or shading them some,” Higgins stated. “If you happen to shade them some — which is what you’re going to do, for instance, in a Wyoming undertaking that’s on non-irrigated lands — you’re going to cut back a few of that warmth stress on these crops. These crops are likely to develop a little bit extra, and as they develop a little bit extra, the sheep reap the benefits of them.”
The research discovered that, whereas the sheep grazing close to the photo voltaic panels skilled a 38 % drop within the amount of grazable vegetation, that was offset by a rise within the out there crops’ high quality, as measured by the dietary make-up of the vegetation’s tissue. Regardless of gaining access to much less vegetation, the sheep grazing close to photo voltaic panels “had been gaining weight at their most fee,” and reached related peak weights to sheep on the open subject, Higgins stated. “We really needed to fence the sheep within the open subject to maintain them within the open subject, as a result of, given the selection, all of them most well-liked to be within the photo voltaic.”

Agrivoltaic photo voltaic farms, whereas appropriate for sheep, are tougher to tailor to cattle, Wyoming’s most typical livestock. The state is dwelling to 1.2 million cattle, that are burlier and heavier than sheep. Cows “simply beat up gear by rubbing up in opposition to it,” Pollpeter stated. The photo voltaic business “is taking a troublesome look to attempt to see how that begins to make sense. However, not less than in my private opinion, we’re not fairly there but.”
Amongst Wyoming’s sheep ranchers, there could also be a budding curiosity in agrivoltaics. “If there are alternatives to make the 2 work collectively that present sheep producers expanded income and higher monetary stability, that’s the kind of factor we search for,” stated Jim Magagna, a longtime sheep rancher and govt vp of the Wyoming Inventory Growers Affiliation, the state’s strongest livestock advocacy group.
Given the variation in soil, grazing crops, daylight, moisture, and terrain throughout Wyoming, Magagna stopped in need of endorsing agrivoltaics because the de facto strategy to photo voltaic farms transferring ahead. “I believe it must be a rigorously thought-about choice by the landowner,” he stated.
Magagna wouldn’t rule out the potential for an agrivoltaic photo voltaic farm cropping up on public land sooner or later, a course of that will contain years of planning and environmental assessments by the Bureau of Land Administration, or BLM, in addition to stakeholder enter. However given the truth that a majority of public lands in Wyoming are grazed by cattle, “I believe the chance to do this on public land on a really vital scale wouldn’t be there at the moment,” he stated.
In January, the BLM launched an environmental impression assertion relating to utility-scale photo voltaic farms in 11 Western states, together with Wyoming, because it considers whether or not or to not amend its strategy to photo voltaic farms within the area. The company acknowledged agrivolatics as an “rising [photovoltaic] system” that would acquire industrial traction sooner or later.
Converse County Commissioners count on to finalize their assist for the Dutchman undertaking allow throughout a February twentieth vote. The corporate nonetheless must safe a allow from the state’s Division of Environmental High quality, whose Industrial Siting Council is already contemplating the corporate’s utility. Ought to the state challenge it a allow, BrightNight expects to interrupt floor on the Dutchman photo voltaic farm as early as March of subsequent 12 months.
