TransAlta reports force majeure for Sundance Units 1 and 2

CALGARY, ALBERTA--(Marketwire - Jan. 4, 2011) - TransAlta Corporation (TSX:TA) (NYSE:TAC) today declared force majeure for its Sundance 1 and 2 coal-fired generation units related to boiler tube conditions above design limits.

All 560 megawatts (MW) from Sundance 1 and 2 will be unavailable up to February 15, as the units will be offline for inspection to determine the scope of repairs that may be needed. Comparable boiler conditions have not been observed at TransAlta's other coal-generation units.

The Alberta Boiler Safety Association (ABSA) indicated immediate shut down of the units was appropriate action consistent with industry safety standards. The units cannot be restarted without ABSA inspection and approval.

TransAlta will provide updates as appropriate when more definitive information becomes available.

Under the terms of its Power Purchase Arrangement (PPA) for these units, TransAlta has notified the PPA buyer and the Balancing Pool of a force majeure event. For the duration of the force majeure period, TransAlta will continue to receive its PPA capacity payments and is protected from having to pay penalties for the units' lack of availability, to the extent the event meets the force majeure criteria set out in the PPA.

Sundance 1 was originally commissioned in 1970 and turns 45 years old in 2015. Sundance 2 was originally commissioned in 1973 and turns 45 years old in 2018. The PPA for both units expires in 2017.

The units are part of the 2,126 MW Sundance power plant, which has six individual units and serves as a baseload facility for the Alberta electricity system. Sundance is located about 70 kilometres west of Edmonton and is the largest power plant in Alberta and the largest coal plant in Western Canada.
