TransAlta strives to maintain relationships through the life cycle of our facilities, from project development and construction, through operation, until decommissioning phases are complete. This is recognized in our Indigenous Relations Policy, which includes acknowledgement and understanding of the intent of the recommendations of the United Nations Declaration on the Rights of Indigenous Peoples. Support for Indigenous Youth, Education and Employment TransAlta recognizes the importance of investing in Indigenous students and our financial support helps students complete their education, become self-sufficient and move forward to become future leaders in their communities. In 2024, TransAlta provided more than $320,000 to support Indigenous youth, education and employment programs, representing 11 per cent of TransAlta’s total community investment. Highlights include:

 elementary students in communities near our operations with in-person and virtual sessions. Read On is an Indigenous literacy program that seeks to mentor young people in First Nation schools to achieve their 
 maximum academic, personal and social development by promoting the core values of education, literacy, taking pride in one’s culture and making good decisions in one’s life.                                    |

 initiative by the Piikani Nation Lands Department aimed at addressing food security and promoting environmental stewardship. The project, titled “Sūṗii ṗo’omaaksin” or “in the spirit of planting seeds,”                                          
 involves the development of a comprehensive greenhouse program that integrates renewable energy technologies and Blackfoot cultural teachings. The program includes a hydroponic farm for year-round food production, educational opportunities for 
 students, and efforts to promote food sustainability and sovereignty within the Piikani Nation community.                                                                                                                                           |
