CALGARY, Alberta (June 2, 2022) – TransAlta Renewables Inc. (TSX: RNW) (the “Company” or “TransAlta Renewables”) announced today that Kent Hills Wind LP (“KHLP”), the Company’s indirect subsidiary, has amended and extended its current power purchase agreements (“PPAs”) with New Brunswick Power Corporation (“NB Power”) in respect of each of the Kent Hills 1, 2 and 3 facilities, representing total generating capacity of 167 MW.  The amending agreements provide for a blend-and-extend of the PPAs for an additional 10-year period through to December 2045.  KHLP is proceeding with its rehabilitation plan to replace the foundations at Kent Hills 1 and 2 and restore the sites to full operation, which is expected to occur in mid-2023.

“Our extended partnership with New Brunswick Power reflects our commitment to our customers and maintains our reputation as a supplier of choice for clean electricity,” said Todd Stack, President.  “Our team has created a solution that meets the needs of New Brunswick Power for both the near and long term, has received the consent of our lenders and allows us to commence site rehabilitation to restore an important source of renewable energy to the region,” added Mr. Stack.

“We are pleased to be extending our relationship with TransAlta to ensure that our customers and grid can continue to rely on the zero-emitting generation of the Kent Hills wind facilities to provide sustainable and affordable energy while also supporting our transition towards a net-zero economy,” said Keith Cronkhite, President and CEO of NB Power.

The PPAs have been extended 10 years to December 31, 2045 and NB Power has also been provided with an effective 10 per cent reduction to the current contract price until 2033.  During the extended period after 2033, the contract price in the agreements have been set to align with current competitive pricing for wind generation and include escalators intended to reflect inflation.  In addition, both parties have agreed to work in good faith to evaluate the installation of a battery energy storage system at Kent Hills and to consider a potential repowering of Kent Hills at the end of life in 2045.  KHLP has also reached an agreement with NB Power regarding the rehabilitation plan that is expected to see the site return to service in mid-2023, in a safe and responsible manner.  KHLP expects to work closely with NB Power throughout the rehabilitation process.

As a result of the determination that all 50 turbine foundations at the Kent Hills 1 and 2 sites require replacement, as well as certain resulting amendments to applicable insurance policies, KHLP provided notice to BNY Trust Company of Canada, as trustee (the “Trustee”) for the approximately $219 million outstanding non-recourse project bonds (the “Bonds”) secured by, among other things, the Kent Hills 1 and 2 wind sites, that events of default may have occurred under the trust indenture governing the terms of the Bonds (the “Bond Indenture”).  Following engagement with the Trustee and holders of the Bonds, KHLP has been able to secure an acceptable waiver of those events of default and has also entered into a supplemental indenture that amends the Bond Indenture and facilitates the rehabilitation of the Kent Hills 1 and 2 sites.

KHLP is now proceeding with its rehabilitation plan which consists of dismantling all 49 remaining turbines, demolishing and removing all existing tower foundations, replacing them with newly-designed foundations, reassembling the wind turbine towers and generators, replacing the wind turbine that collapsed, and testing each wind turbine generator before returning it to service.  KHLP has entered into agreements with Bird Construction Industrial Services Ltd. and Vestas-Canadian Wind Technology, Inc. to complete the rehabilitation.

Rehabilitation for the Kent Hills 1 and 2 sites is targeted to be completed by mid-2023.  Each turbine at Kent Hills 1 and 2 will be re-energized and returned to service as soon as its foundation is replaced and the turbine is reassembled and tested.  The current estimate of the total rehabilitation expenditures is approximately $120 million, net of insurance proceeds, and inclusive of contingency.  The Company and KHLP intend to pursue claims to recover costs and related damages from third parties.

The 167 MW Kent Hills facilities are located near Moncton, in Albert County, New Brunswick and were completed in three phases consisting of 50 turbines at Kent Hills 1 and Kent Hills 2, which achieved commercial operations in December 2008 and November 2010, respectively; and five turbines at Kent Hills 3, which began commercial operations in October 2018.  Natural Forces Technologies Inc. owns a 17 per cent interest in respect of each of the Kent Hills 1, 2 and 3 facilities through its ownership interest in KHLP.
