CALGARY, Alberta (October 29, 2021) – TransAlta Renewables Inc. (“TransAlta Renewables” or the “Company”) (TSX: RNW) announced today further operational updates in respect of the 167 MW Kent Hills wind facility in Kent Hills, New Brunswick (the “Facility”) owned by its indirect subsidiary, Kent Hills Wind LP (“KHW”), in which Natural Forces Technologies owns a 17% interest.  The Facility was completed in three phases and consists of 50 turbines at Kent Hills 1 and Kent Hills 2, which achieved commercial operation in December 2008 and November 2010, respectively; and five turbines at Kent Hills 3, which began commercial operations in October 2018.   As a result of a tower collapse at the Kent Hills 2 site, the turbines at the Kent Hills 1 and Kent Hills 2 sites have been taken offline pending a satisfactory independent engineering and safety assessment. 


The independent engineering and safety assessment, which is ongoing, has identified sub-surface crack propagation at several of the foundations of the turbines located at the Kent Hills 1 and Kent Hills 2 sites.  This suggests that certain foundations will likely need repair or replacement.  As a result, further inspection and testing will be required for each of the turbines at Kent Hills 1 and 2 to determine the required remediation plan, if any, on a turbine-by-turbine basis.  It is our goal to safely return to service those turbines that are deemed acceptable following this further inspection and testing, while concurrently performing remediation on those foundations that are identified as requiring repairs or replacement.  It is currently estimated that the cost of replacing a turbine foundation, if required, could be $1.5 million to $2.0 million per foundation and it is our current expectation that the the remediation plan would be implemented during the course of 2022.  The foundation issues at the Kent Hills 1 and Kent Hills 2 sites are unique to the design of those sites and there is no indication of any foundation issue at the Kent Hills 3 site or the Company’s other wind sites. 


“The Company is committed to working with our customer and other stakeholders as we remediate the foundations.  We are focused on returning the wind turbines back to service as soon as reasonably practicable while adhering to the highest standards of safety and prudent operating practice”, said Todd Stack, President of TransAlta Renewables.  


KHW will not collect any payments from New Brunswick Power Corporation (“NB Power”) in respect of those wind turbines at the Kent Hills 1 and Kent Hills 2 sites until such time that they return to service and generate wind energy output.  This outage is expected to result in foregone revenue of approximately $3.7 million per month for so long as all 50 turbines are offline, based on average historical wind production, with incremental revenue expected to be earned as wind turbines are returned to service.   The Kent Hills 3 power purchase agreement and site remain unimpacted and the turbines at that site continue to operate and generate revenue.  KHW has been in contact with NB Power to keep them informed of developments and to ensure the safety of the site.        


As a result of the expected foregone revenue through the remainder of 2021, the Company now forecasts its key 2021 financial targets and related assumptions to be slightly lower relative to its previous guidance range, as set forth below:
