Mayo Relicensing Project

Our current water use licence for the Mayo hydro facility expires on December 31, 2025. To continue to generate electricity, and to continue to provide Yukoners with renewable electricity, we need to renew our water use licence. As part of this, we are looking to put long-term processes in place that will allow us to continuously monitor and adapt to changing climate conditions, respond to community input, and minimize our impact on the environment.

We recognize the importance of working collaboratively with First Nations governments and are applying lessons learned from other relicensing processes to this project. In 2022, we started discussions with the First Nation of Na-cho Nyäk Dun so as to understand their interests and values in the facility and the relicensing process. We will continue to have these discussions as the project continues.
