Berkshire Hathaway Energy and Renewable Energy Systems are the latest developers to unveil a renewable energy project in Alberta as the Canadian province exerts its allure on local and international sponsors.

The two firms have signed a power purchase agreement with a large, Canadian corporate offtaker for a 117.6 MW wind farm they are jointly developing in Alberta.

Construction of the C$200 million ($151.2 million) Rattlesnake Ridge wind farm is slated to start in Medicine Hat next year. The project is scheduled to be online in December 2021.

“The Rattlesnake Ridge Wind project is a leader in the development of new grid-scale wind generation in Alberta, being constructed and operated without government subsidies,” said William Christensen, vice president of corporate development at BHE Canada, the local subsidiary of Berkshire Hathaway Energy, in a statement.

Other sponsors with projects in Alberta, such as Canadian Solar, Greengate Power Corp. and Perimeter Solar, have also emphasized the fact that development is continuing without subsidies after the United Conservative Party government reversed the renewable energy policies of the previous provincial regime (PFR, 10/6/19).

BHE Canada and RES are also looking for offtakers for another project in southeastern Alberta, the 398.5 MW Forty Mile Wind Farm.

In neighboring Saskatchewan, meanwhile, SaskPower is preparing to launch a request for proposals for 300 MW of wind capacity to come online in 2023 or 2024.

The winner of a previous wind tender in Saskatchewan, Potentia Renewables, recently approached the market to finance its 200 MW Golden South Wind Project in Assiniboia based on a 25-year contract (PFR, 9/19).  In 2018, developer Saturn Power signed a 20-year PPA with SaskPower for the province's first utility-scale solar project (PFR, 6/20/18).

Here’s the rest of this week’s PPA news:

Where there’s a Wells…

Wells Fargo has signed a 10-year structured renewable energy agreement with Reliant Energy, the Texas retail energy subsidiary of NRG Energy.

The deal is not a power purchase agreement but will result in the construction of a utility-scale solar project in Texas by 2021, according to an announcement. Construction on the unnamed project is due to begin in 2020.

Tiempo suplementario

Argentina's Undersecretariat of Renewable Energy has extended the deadline to present reworked offers for projects that qualified for the third round of its renewables procurement program, RenovAr, but were not awarded PPAs.

The government's goal for the auction was to procure small-scale renewable projects totaling 400 MW (PFR, 5/3). When the auction was held, in July, 38 renewable projects totaling 259 MW won contracts.

Projects that did not clear the price assigned for each technology type are encouraged to present reworked offers by Monday, Oct. 21.

Uruguay Postpones Solar Tender

Uruguay’s Administración Nacional de Usinas y Transmisiones Eléctricas (UTE) has postponed the tender for a 65 MW solar project.

Although UTE had begun accepting bids for the project, located in Punta del Tigre, San José, on Oct. 25, the company has postponed the bidding process until Nov. 26 after several bidders requested a delay.

The bids are for turnkey design and construction contracts—UTE says it will procure the solar panels.
