TransAlta Corporation Debuts New Brand Reiterating Commitment to a Clean Energy Future

Today, TransAlta Corporation (TSX: TA; NYSE: TAC) (“TransAlta”) announced a new visual identity including logo and tagline. The new visual identity encapsulates the TransAlta of today while reinforcing the Company’s focus as a leader in creating a carbon-neutral future for our customers.

This rebranding coincides with a key milestone for the company – 111 years have passed since the company first began generating power in the foothills west of Calgary.

With a diversified portfolio of generation assets that includes wind, solar, hydro and gas, operating in Canada, the United States and Australia, and a robust portfolio of growth projects, TransAlta is well-positioned to support the global effort to decarbonize with the clean, reliable, and low-cost electricity customers need to successfully transition.

“Today, we are presenting a new look to our customers and stakeholders, one that speaks to a clean future and aligns with our company’s purpose statement that clean power is fundamental to moving the world forward,” said President and CEO John Kousinioris. “From our transition off coal in Canada to the renewable projects we are building and operating for our customers, it is a proud moment for our Company. Our new visual identity conveys that TransAlta is moving forward with purpose having made the investments necessary to achieve significant carbon reductions in our generation portfolio while building out a renewables fleet that will help our customers achieve their decarbonization goals. We truly are energizing the future.”

For our customers, our employees, and the communities in which we operate, TransAlta’s new brand stands for momentum, evolution and energy. The brand is bold, dynamic, and progressive.

Brand updates include:

Updated logo design – the custom-designed logo gives a nod to our core business. The three “A”s in the Company name resemble electrical coils, in perpetual motion and represent the change in and evolution of the sector in general and TransAlta in particular. The Company will focus on the conversion of all digital and physical assets of its brand, signage, and materials for the remainder of 2022 and into 2023.

New tagline – “Energizing the Future.”

New website – The Company’s external website has been transformed to reflect the new brand and functionality to meet the needs of customers, investors, and stakeholders.
