TransAlta Advances its Clean Energy Investment Plan

CALGARY, Oct. 30, 2019 /PRNewswire/ - TransAlta Corporation ("TransAlta" or the "Company") (TSX: TA) (NYSE: TAC) announced today that it has entered into an agreement with Kineticor Holdings Limited Partnership #2 to indirectly acquire two 230 MW Siemens F class gas turbines and related equipment for $84 million.  The transaction also results in the Company assuming long-term non-unit contingent power purchase agreements starting in late 2023 with Shell Energy North America (Canada) ("Shell"). TransAlta will redeploy these assets to its Sundance site as part of its strategy to repower Sundance Unit 5 to a highly efficient combined cycle unit by integrating these gas turbines into the existing steam turbine at Sundance Unit 5.     

This transaction has significant benefits, including:

• Advances the Company's strategy of becoming a low cost, low emissions power generation company;
• Significantly reduces TransAlta's post-2020 merchant risk by securing between 210 MW and 420 MW of long-term power contracts with Shell, a strong investment grade company that is committed to providing more and cleaner energy for Alberta;
• Reduces the time to design and construct the repowered combined cycle unit by three to six months;
• Results in a lower capital outlay, by approximately $230 million, for the repowered combined cycle strategy;
• Provides the Company with more operational flexibility by integrating two gas turbines into one steam turbine (rather than two steam turbines); and
• Maintains the option to repower the Keephills 1 unit to a combined cycle unit or to convert the unit to gas via a boiler conversion at a later date, depending in each case on market fundamentals.

The Sundance 5 repowered combined cycle unit will have a capacity of approximately 730 MW and is expected to cost approximately $760 million, well below a greenfield combined cycle project. TransAlta expects to achieve commercial operation in 2023.

"The acquisition advances our repowering strategy in Alberta and increases our contractedness which will help de-risk our business as we move into a fully merchant Alberta market starting in 2021," said Dawn Farrell, President and Chief Executive Officer of TransAlta. "We are very pleased for the opportunity to have Shell as a major customer and look forward to working with them on this opportunity to provide low cost, clean and reliable power for Albertans."
