United States

TransAlta began operations in the United States in 2000 with the purchase of our Centralia plant in Washington State. Since then, we have expanded our generation to Wyoming, Minnesota, Massachusetts and coming in 2019, Pennsylvania. We have five U.S. facilities that have the capacity to produce more than 1,500 MW of reliable energy from sources including coal, hydro, solar and wind.

The signing of the TransAlta Energy Transition Bill in early 2011 represents significant collaboration among policymakers, environmentalists, labor leaders and TransAlta around the common goal of reducing emissions from energy production without unduly disrupting the local economy. Through all sides listening to each other’s concerns and setting realistic expectations, an agreement was established that provides opportunities for the company to plan long-term growth across the Pacific Northwest.

The bill provides for the orderly transition of the Centralia plant from coal in 2020 and 2025 and allows TransAlta to grow and maintain a presence in the power market while protecting jobs and the community through the $55 million we have set aside to assist with the transition. We are uniquely suited to fill the need for replacement generation with plans to convert the Centralia facility to natural gas.

TransAlta committed to invest $55 million into the local community and the state of Washington to support energy efficiency, economic and community development and education and retraining initiatives. For more information on the Centralia Coal Transition Funding Boards visit www.cctgrants.com
