ATCO, through its investment in Canadian Utilities Limited, has successfully closed the previously announced acquisition of a portfolio of wind and solar assets and projects located in Alberta and Ontario from Suncor Energy Inc. Concurrent with the close of this acquisition, ATCO entered into a new 15-year renewable energy purchase agreement (REPA) with Microsoft Corporation. Under the terms of the agreement, Microsoft will purchase 150 megawatts (MW) of renewable energy generated by ATCO´s newly acquired Forty Mile Wind Phase 1 Project in Alberta. The Forty Mile Wind Phase 1 project is the second REPA ATCO has signed in the past year with Microsoft.

In March 2022, ATCO signed a 15-year REPA for Microsoft to purchase all renewable energy generated by ATCO's Deerfoot Solar Project located in Calgary, Alberta, one of the largest solar installations in a major urban center in Western Canada. Customers buying through REPAs represents a long-term collaboration that helps to bring new clean electricity generation online. It also provides a demand signal to spur the development of new clean energy solutions.

ATCO´s 202 MW Forty Mile Wind project is located in southeastern Alberta, in the County of Forty Mile. ATCO has successfully begun operating the Forty Mile Wind facility as well as the 30 MW Adelaide wind facility in Ontario.
