TransAlta scraps wind farm project as energy market changes loom for Alberta

TransAlta, one of Alberta's largest power generators, has cancelled a proposed wind farmdevelopment and is putting a hold on three other power projects, citingprovincial rule changes and a lack of certainty in the market.

In February, Alberta'sgovernment announced new rules on the development of renewable power in the province. They imposed a new35-kilometre buffer zonearound areas deemed "pristine viewscapes."

Calgary-based TransAlta said those rules, coupled with a lack of clarity around the future of renewable energy in Alberta, led to the decision to permanently scrap the Riplingerwind projectnear Cardston, Alta.

The company began looking into the 300-megawattwind farm in 2020, and has done studies to assess its environmental impact. It was expected to come online in 2027.

"As we take stock of the government of Alberta's regulatory announcements, we reassessed our own growth plans in the province," said TransAlta CEO John Kousiniorisduring a first-quarter results call on Friday.

Some local residents who live near Waterton, Alta., are celebrating the decision. Bed and breakfast owner Angela Tabak,with the Riplinger Wind Concerned Citizens, says fighting against the project becamea full-time job.

"We've spent the last year contacting every government official that we can get our hands on," she told CBC News in late March."We have sat in the premier's office with her and a number of folks from different ministries. We have sat with the environment minister and laid out our case."

Concerns about tourism, birds

She thinks theproject would affect tourism.

The no-go zone rule followed a seven-month moratorium on renewable energy approvals after the government decided the industry was growing too quickly, threatening agriculture and marring Alberta's landscape.

A map released in Marchshows thatthe buffer zoneincludes the entire length of the Rocky Mountains, stretching as far east as Calgary andsouth to the U.S. border.Kousinioris says TransAlta'sRiplinger project would have been on the edge of an exclusion zone.

"I really believe it was probably this project that finally triggered that moratorium when it was so obvious that things were completely out of control," said Tabak.

Her group also had concerns about the impact on birds fatally caught up in the turbine blades,and other animals in the rich biodiverselandscape of the area whichUNESCO designateda World Heritage Site in1995.

She says she's not against renewables, and just put $40,000 worth ofsolar panels on her property.

Jason Wang, an analyst with the clean energy think-tank Pembina Institute,says 57 projects worth $14 billionare affected by visual impact zones or the agricultural land-class restrictions released by the government.

He saiddespite the impacts on birds, which is a concern, human-caused climate change from burning fossil fuelsis expected to have a devastating effect on all wildlife on the planet. Some experts predict a mass extinction of animalsis already underway.

He says pivoting to renewable energy should be our main priority, and now Alberta might lose out on investments especially in areas of the provincethat see a lot of wind, like near the mountains.

"Many of these folks are the ones that, you know, have already said they might be looking at other jurisdictions," said Wang about some renewable companies.

The moratorium's lasting impact

Wang says key details for many projects in limbo still haven't been released. He says that essentially means the moratorium recently lifted is still in effect, and he worries about the impact on First Nations who want take control of their power needs.

Alberta's Ministry of Affordability and Utilities says "viewscape"rules were developed based off stakeholder feedback and how other jurisdictionssuch asB.C., California and the U.K.have approached theissue.

A spokesperson for the ministry said Pembina's estimatesare "are solely speculation," and "not accurate nor reflective of the number of projects [waiting for approval]nor the amount of investment impacted." They also don't affect projects currently operating in the area, as there are hundreds of wind turbines dotting the horizon north of Waterton nearPincher Creek, Alta.

"These new rules apply to all new projects undergoing the approvals process with the Alberta Utilities Commission (AUC) as of March 1. They are not retroactive, and therefore do not apply to existing projects," saidMinister Nathan Neudorfin an emailed statement to CBC News.

"The AUC has already moved forward with issuing new decisions on project applications, with the vast majority being approvals. We recognize that First Nations set their own land-use policies with the federal government for reserve lands, and our enhanced land-use rules are not designed to apply to those areas."

When asked why other industries such as the widespread logging proposed for West Bragg Creek that locals think will have an impact on tourism and the majestic views are not affected by the new rules,the ministry saidthat falls outside of its purviewand questions would have to be directed to the government's environment, forestry and energy departments.

3 other TransAlta projects onhold

TransAlta'sKousinioris said the province's looming market redesign has forced the company to reconsider other plans as well.

The company has put on hold the180-megawattWaterChargerbattery storage facility near Cochrane, the 100-megawattTempest wind project south of Lethbridge, and the 44-megawattPinnacle generator west of Edmonton.

"These projects all have varying degrees of merchant market exposure and have been put on hold until we receive sufficient clarity regarding the future market structure and the impact of changing frameworks on resulting market prices," saidKousinioris.

According to Kousinioris,twoof the developments put on hold were quitenovel projects.

WaterCharger, the largest of the halted projects, is a 180-megawatt battery storage project that would sit on roughly nine acres of land 18 kilometres west of Cochrane. Itwas expected to be completed this year.

The facility, according to TransAlta, is designed to be charged by electricity produced by the existing Ghost hydroelectric plant when demand is lower.

During times of higher demand, power from the new facilitywouldbe discharged to support the electric grid.

Pinnacle, a 44-megawatt thermal project in Parkland County, Alta., was expected to generate around 60,000 megawatt-hours of electricity by2025 its expected first year ofoperation before being placed on hold.

"We're very careful with our shareholders' money, and we're not going to invest in these kinds of projects unless we have a good level of comfort that our return expectations are going to be met,"Kousinioris said.

Tempest isanother wind farm that TransAlta started developing in 2006. It's a 99-megawatt project located approximately 15 kilometres east of Stirling, Alta., in Warner County.

"The other projects are on hold,they're not cancelled," Kousinioris said, adding thathis team is working to preserve them and will move them forward once they get the clarity they need.

"There are things that that could be resurrected and investments that could be made there."
