Company gets OK for $253 million wind farm, energy storage in central Montana

RAPELJE — The properties are few and much between on the excessive plains that sweep between Rapelje and Reed Level. Although distant, the world is poised to mark a primary in Montana: a spot the place the ability of wind shall be saved.

Final month, Stillwater County authorised two phases of a wind farm that may incorporate massive batteries for storing vitality. The brand new-to-Montana idea addresses what skeptics fault about wind energy: that it’s inconsistent and unreliable.

The batteries supply a strategy to offset the vagaries of wind by storing extra vitality when demand is low and tapping that vitality when demand peaks.

The allow was the final field to be checked for Beaver Creek Wind Farms II and III. Every venture is rated at 80 megawatts of energy slated for NorthWestern Vitality’s system by way of transmission strains roughly 4 miles from the proposed farms. Caithness Beaver Creek, the New York firm growing the wind farms, estimates the 2 phases may energy almost 115,000 properties.  

Whereas wind farms will not be new to Montana, the incorporation of batteries is.

Derrel Grant, senior vice chairman of improvement for Caithness Beaver Creek, refers back to the mannequin as a hybrid wind and storage facility.

“It’s a novel utilization of the applied sciences,” he mentioned. “It is perhaps new to Montana, however it’s not new to the business.”

In some locations, builders have lassoed the ability of the wind utilizing water as a “battery.” When wind vitality exceeds demand, water is pumped into an elevated reservoir. When demand outstrips manufacturing, the water is launched, flowing down and creating hydro vitality.

The Beaver Creek initiatives, nevertheless, will depend on lithium-ion batteries that may “agency up” the wind energy by smoothing out the highs and lows of the wind so the output shall be extra constant. Grant describes the batteries as considerably like these in an electrical automobile, solely on a a lot bigger scale. They are going to be saved in containers that occupy about three acres of the wind farm. In line with Caithness, the batteries will present roughly three-and-a-half to 4 hours of storage. Which means if the batteries are full and the wind stops blowing, they are going to produce 20 megawatts of energy for that period.

“Within the energy business, we wish energy to be regular throughout discrete intervals of time,” Grant mentioned. “The batteries can clean out that energy to place into the grid.”

The Stillwater County commissioners are impressed by the expertise however ready to see how the venture pans out. Fee Chairman Ty Hamilton was initially involved the large batteries would possibly pose a fireplace danger, however he famous that Caithness has included sprinklers into its design.

Typically, the commissioners had much less to say concerning the novel idea than about normal points related to wind farms and their development. The Beaver Creek initiatives received’t be the county’s first rodeo, having not too long ago skilled the development of Sample Vitality’s Stillwater Wind, an working wind farm adjoining to the proposed Beaver Creek initiatives.

Street impacts, taxes, financial diversification and public opinion topped the listing of their concerns, together with a number of classes discovered from expertise — all of which had been the main target of situations listed within the county’s allow. The commissioners heard few feedback relating to the visible affect of the proposed wind farm, however heard loads when it got here to higher communication from the corporate to native residents.

“We’re speaking a number of site visitors on these roads and a number of massive masses,” Hamilton mentioned. “These roads are used for agricultural functions, so we needed to ensure the landowners are alerted when these masses are anticipated. That was an enormous ask of the general public.”

There are each winners and losers amongst space landowners. The Eder place is without doubt one of the former.

The late Delbert Eder had lengthy championed a wind farm within the space however didn’t reside to see it. Sample Vitality’s farm is simply throughout the street from the household place, and now Beaver Creek II and III shall be constructed on their land, which is at present getting used for cattle grazing and hay manufacturing.

Eder’s son Loren, who lives in Columbus, mentioned his father envisioned the wind farm not simply as a strategy to generate electrical energy, but additionally as a further useful resource to assist pay the payments. “He noticed it like elevating different crops or bettering genetics,” Loren Eder mentioned. “It’s no matter you are able to do to make a greater product.” Eder wish to see the vitality “keep native,” however admits he has little say in that call.

“Undoubtedly, within the [construction] course of it would intrude with grazing, and it’ll take some floor out of manufacturing,” he mentioned. “It’s like constructing a home. The method is a headache, however, when all is alleged and executed, it’s effectively well worth the effort.”

Bob VanOosten’s ranch, situated a number of miles from the Eder’s, shouldn’t be a part of the wind farm’s footprint. He received’t profit from lease funds or royalties, however he’ll take care of development associated points.

“The existence of a wind farm there’s irrelevant,” VanOosten mentioned. “It received’t give us cheaper electrical energy. However we get to benefit from the impacts.”

Throughout development of Sample Vitality’s venture, VanOosten counted 100 loaded semis and a minimum of 100 different autos passing by every day — utilizing a street that had beforehand been traveled solely flippantly by locals. The street took a beating and dirt typically made driving situations harmful. VanOosten himself was concerned in a collision when a subcontractor took greater than his share of the street.

VanOosten doesn’t oppose the initiatives, however he hopes the development shall be much less onerous this time.

As for the battery facet of the upcoming wind farms, he admitted curiosity.

“It’s a cool idea,” he mentioned. “I’ll be begging for a tour to see the battery advanced when it’s executed.”

The county’s allow doesn’t deal with chook fatalities, an issue typically related to wind farms. Grant mentioned Caithness performed detailed surveys that decided the venture’s affect on birds can be insignificant. 

Caithness estimates Beaver Creek II and III will make use of 175 employees through the year-long development section and 16 to twenty everlasting, on-site employees after completion. In line with the corporate, the 48 wind generators of every section will mix to generate 4.5% of the whole renewable vitality at present produced in Montana.

The value tag for setting up the 2 initiatives is estimated at $253 million. The wind farms are projected to usher in $48 million in property taxes over 25 years and qualify for tax rebates via the primary 10 years. Considerably offsetting the rebates, Caithness has agreed to pay Stillwater County roughly $1.265 million in affect charges — a determine that may differ relying on the ultimate value of the venture — for every of the primary three years.

“This begins to diversify Stillwater County’s tax base to the place there’s not a lot reliance on Stillwater [Mining Company],” mentioned former Stillwater County Commissioner Mark Crago, who was instrumental in bringing the initiatives to the county.

In the end, two extra phases — Beaver Creek I and IV — are deliberate. With all 4 phases throughout 20,000 acres, the wind farms will generate sufficient vitality to energy roughly 227,000 properties.

Caithness plans to start out development this summer season. Generators and storage services shall be put in subsequent spring, and — barring unexpected hold-ups — the wind farm is scheduled to be in service by the tip of 2023.
