Augments and further diversifies TransAlta's portfolio in Alberta's energy-only market
Enhances TransAlta's competitive positioning in the highly dynamic and shifting electricity landscape in Alberta

With this acquisition we are pleased to announce the addition of highly flexible and complementary assets to our Alberta portfolio. As the energy transition continues to drive new investment in renewables in the Province, our assessment is that the market will require low-cost, highly flexible and fast-responding generation, which will be supportive to grid reliability over the coming years. This transaction will support us in maintaining our competitive positioning and ensure we have a robust and diversified portfolio, which together with our marketing capabilities, can complement and support a cleaner grid," said John Kousinioris, President and Chief Executive Officer of TransAlta.

"The Heartland portfolio is low cost and will contribute meaningful cash flows with significant value from synergies. It will also support the energy transition until other zero-emitting solutions are developed. We remain committed to our Clean Electricity Growth Plan and net-zero targets. The acquisition of this set of assets represents a strategic investment in our home market with a strong return profile which continues to be aligned with our longer term decarbonization goals," added Mr. Kousinioris.

"ECP is proud of the transition progress that Heartland has made since its acquisition in 2019 through our early coal conversions and the advancements of the Battle River Carbon Hub, all the while consistently delivering reliable electricity to the Province. We are excited for TransAlta to continue advancing the energy transition and meeting the reliability and electricity needs of Alberta," said Andrew Gilbert, ECP Partner.

Investment Highlights

The transaction is strategically attractive to TransAlta and provides the following benefits:

Expands Flexible Generation Capabilities: Augments and diversifies TransAlta's portfolio in Alberta's energy-only market by expanding its flexible and fast-ramping capacity and marketing capabilities to be able to better respond to changes in market conditions stemming from the intermittency of increasing renewable generation.
Enhances TransAlta's Competitive Positioning: The acquisition will competitively position TransAlta in response to the changing dynamics in Alberta given the expected significant increase in renewables and other large baseload generation coming online in the next several years in the highly dynamic and shifting electricity landscape in the province.
Aligned with TransAlta's Alberta Strategy: The portfolio delivers a highly-responsive, flexible and fast-ramping fleet (peaking units) which will be supportive to responsible energy transition and deliver reliability in the Alberta electricity market for the next 10 to 15 years.
Attractive Transaction Metrics: The acquisition is highly accretive to free cash flow with an attractive multiple and strong cash yield. The transaction acquires a portfolio of assets at approximately $357 per kW, which is well below replacement cost of current and other forms of reliable generation, providing a low-cost expansion of our ability to deliver reliable generation to the market demands of Alberta.
Highly Contracted Cash Flow: Post-closing, the assets are expected to add approximately $115 million of average annual EBITDA including synergies. Approximately, 55 per cent of revenues are under contract with high creditworthy counterparties which have a weighted-average remaining contract life of 16 years.
Near-term Synergies: TransAlta will have the opportunity to leverage corporate costs within our existing business which will provide estimated corporate pre-tax synergies of $20 million annually. In addition, the combined portfolio will enable the Company to further optimize operations and supply chains through scale to achieve additional synergies in the future.
Retains Ownership Presence in Alberta and Builds On Regional Expertise: The Company is well positioned to deliver significant value through our deep technical gas and cogeneration local operational experience which, together with our 112-year history in Alberta, will ensure continuing safe and reliable generation in a dynamic and evolving landscape.
Battle River Carbon Hub Project: This project is a first-of-its-kind 400 MW integrated clean energy project, combining clean hydrogen, production and carbon sequestration, to create a zero-carbon baseload electricity solution. The project would retrofit the existing generation facility at Battle River and utilize the existing transmission infrastructure, which will minimize development costs for a zero-carbon power solution.
Maintains Leadership in Decarbonization: TransAlta remains among Canada's largest producers of wind power and Alberta's largest producer of hydroelectric power. The Clean Electricity Growth Plan continues to be at the heart of our strategy and is dedicated to meeting the future needs of our customers with clean electricity solutions. TransAlta's ability to meet its 2026 GHG emissions reduction target and carbon net zero by 2045 remain on track.  This acquisition adds to TransAlta's 4.6 GW development pipeline with the addition of a 400 MW hydrogen carbon hub opportunity.

Additional Information on the Agreement

The Agreement is subject to customary closing conditions, including receipt of regulatory approvals. The transaction is expected to close in the first half of 2024.
