Sundance 7

Latest Update: Sundance 7 Receives AUC Approval For Time Extension

The Alberta Utilities Commission (AUC) and Alberta Environment and Parks (AEP) have given approval to TAMA Power to build Sundance 7, an 856 MW high efficiency natural gas-fired electricity generating plant in Alberta.

In February 2016, the AUC issued an approval decision for a time extension to construct the Sundance 7 Power Plant. As stated in the decision, “unless otherwise authorized by the Commission, construction of the power plant shall be completed by December 31, 2022.”

Power Plant Approval – 21062-D02-2016

In October 2015, Alberta Environment and Parks issued the Environmental Protection and Enhancement Act approval for Sundance 7.  This approval can be viewed at:

Discussions with customers on long-term contracts for the facility are ongoing and will be part of the final investment decision.

Sundance 7 significantly expands TransAlta’s growing gas-fired generating capacity. The new plant, to be located in Parkland County, west of Edmonton, will use proven, best-in-class gas turbine technology combined with steam plant technology. Waste heat will be captured from gas turbines and used to operate a highly efficient steam turbine, further increasing the environmental efficiency of Sundance 7.

TransAlta Corporation and MidAmerican Energy Holdings Company joined forces to create TransAlta MidAmerican Partnership (“TAMA Power”) in October 2012.  TAMA Power is committed to building reliable, economical and environmentally responsible natural gas fueled power generation facilities for Albertans.

Sundance 7 is planned to be a combined-cycle natural gas generation facility. With a gross generation capacity of 856 megawatts (MW), the plant will generate enough electricity to power approximately 720,000 Alberta households.

TransAlta will, for TAMA Power construct, manage, operate and maintain Sundance 7. TransAlta will also lead engagement and consultation with the community on behalf of the TAMA Power Partnership.
