Key Points

  • TransAlta Corp. has joined over 30 other water licence holders in the Bow River basin in signing a voluntary water-sharing memorandum of understanding (MOU), initiated by the government of Alberta to coordinate water needs in anticipation of a lower-water year in Southern Alberta.
  • Given its responsibility for managing water storage, flows, and hydroelectric power generation in the Bow River system, TransAlta is collaborating with downstream water licence holders to optimize water management strategies, particularly during spring run-off and summer months, to mitigate potential drought conditions.
  • The company anticipates that its participation in this voluntary arrangement will align with its electricity generation objectives and practices. TransAlta does not expect this initiative to significantly impact the performance of its hydro fleet, with hydro operations expected to remain consistent with the company’s guidance for 2024. Additionally, TransAlta emphasizes its commitment to meeting environmental obligations and contributing to sustainable development goals through its operational practices.

TransAlta Corp. has signed onto a voluntary water-sharing memorandum of understanding (MOU) with over 30 other water licence holders in the Bow River basin.

Water-sharing MOUs have been initiated by the government of Alberta across Southern Alberta, to co-ordinate water needs in what is expected to be a lower-water year.

Due to its role managing water storage and water flows in the Bow River system for power generation, drought prevention and flood control, the company is collaborating with other downstream water licence holders to manage water flows.

TransAlta will contribute to this effort by maximizing storage of run-off in the spring and then use that water to manage river flows during the summer. The MOUs do not include TransAlta’s facilities on the North Saskatchewan River system.

“TransAlta recognizes the unique role our Bow River system plays in managing water flows while also serving as a key component of Alberta’s electricity grid. We look forward to working with the government and downstream licence holders to maximize water storage in the spring, and sustain water flow during the summer months to help mitigate drought conditions, should they occur,” said Blain van Melle, executive vice-president, commercial and customer relations.

TransAlta expects these water management efforts during the spring and summer seasons to align with its electricity generation objectives and practices. The company does not expect this voluntary arrangement to have a material impact on the performance of TransAlta’s hydro fleet and hydro operations are expected to perform consistent with the company’s guidance range for 2024 based on current water forecasts. TransAlta continues to retain full capacity and capability to respond when these hydro facilities are needed by the electricity grid and will continue to meet environmental obligations.
