TransAlta Announces Receipt of Termination Notices from TransCanada and ASTC Power Partnership

CALGARY, Alberta (March 8, 2016) – TransAlta Corporation (“TransAlta” or the “Company”) (TSX: TA; NYSE: TAC) today announced it had received formal notice from TransCanada Energy Ltd. (“TransCanada”) of its intention to terminate the Power Purchase Arrangements (the “PPAs”) for Sundance A Units 1 and 2 and Sheerness Units 1 and 2 and formal notice from ASTC Power Partnership (“ASTC”), a partnership between TransCanada and AltaGas Pipeline Partnership, of its intention to terminate the PPA for Sundance B Units 3 and 4. Notwithstanding the termination, the terms of the Sundance A and B and Sheerness PPAs remain intact and will be administered by the Alberta Balancing Pool.

The terminations are not anticipated to have a material impact on TransAlta’s business. The Balancing Pool is now required to verify TransCanada’s and ASTC’s determinations and confirm their right to terminate the PPAs. Should the termination be accepted, the Balancing Pool will act as the Buyer of the Sundance A, Sundance B and Sheerness PPAs and will be responsible for offering the capacity into the market and making the PPA payments previously made by TransCanada and ASTC to TransAlta.

TransAlta will continue to focus on cost-effective and efficient operation of its Canadian Coal facilities and will work with the Government of Alberta to reach an agreement on the path forward for coal. The government is expected to appoint a negotiator to work with coal generators to ensure system reliability, price stability and no unnecessarily stranded capital. TransAlta will negotiate with the government to ensure that the Alberta electricity market structure supports the development of renewable assets as the Province transitions away from coal.
