CALGARY, Alberta (April 5, 2022) TransAlta Corporation (“TransAlta” or the “Company”) (TSX: TA) (NYSE: TAC) announced today that it has entered into a long-term renewable energy purchase  agreement with Meta, formerly known as the Facebook company, for the offtake of 100 per cent of the generation from its 200 MW Horizon Hill Wind Power Project (“Horizon Hill” or “facility”), to be located in Logan County, Oklahoma. Under this agreement, Meta will receive both renewable electricity and environmental attributes. This long-term contract with Meta enables TransAlta to add the 200 MW Horizon Hill Wind Project to its growing US wind generation fleet.

“Since 2020, Meta has supported its global operations with 100 per cent wind and solar energy. As our footprint grows, it’s key that we find strong partners who can help us continue to meet that goal by bringing new renewable energy to the grid,” said Urvi Parekh, head of renewable energy at Meta. “We are excited to partner with TransAlta to make this 200 MW project a reality.”

“TransAlta is excited to partner with Meta to make Horizon Hill a reality. The delivery of clean, low-cost, reliable energy from Horizon Hill supports Meta’s sustainability goals and provides another excellent opportunity to expand our wind fleet in the United States,” said John Kousinioris, President and Chief Executive Officer of TransAlta. “Horizon Hill brings us to 40 per cent of our target of adding 2 GW of new renewables to our fleet by 2025 under our Clean Electricity Growth Plan.”

The facility will consist of a total of 34 Vestas turbines with construction expected to begin in Q4 2022 and a target commercial operation date in the second half of 2023. TransAlta will construct, operate and own the facility. Total project capital is estimated at approximately US$290 million to US$310 million and is expected to be financed with existing liquidity and tax equity. Over 90 per cent of the project costs are captured under executed fixed price turbine supply agreements with Vestas and executed engineering, procurement, and construction agreement with Infrastructure and Energy Alternatives (“IEA”). The facility is expected to generate total annual earnings before interest, taxes, depreciation and amortization (“EBITDA”) of approximately US$27 million to US$30 million including production tax credits.  It is expected that Horizon Hill will remain a TransAlta project.
