The Alberta Utilities Commission on Aug. 28 approved a reshuffling of the timeable and interconnection needs of two wind projects being developed by NaturEner Energy Canada Inc.
NaturEner already has commission approvals for the Wild Rose 1 (WR1) and Wild Rose 2 (WR2) wind plants, to be located approximately 50 kilometers southeast of Medicine Hat. The original in-service date for the WR1 wind power plant was Dec. 31, 2014, which was subsequently extended to Dec. 31, 2015. The original in-service date for WR2 was Oct. 13, 2013, which was subsequently extended to Dec. 31, 2015, and then to Dec. 31, 2016.
The Alberta Electric System Operator (AESO) informed the commission that NaturEner has changed the requested in-service dates for the WR1 and WR2 wind power plants such that the WR2 power plant will now be in-service before the WR1 power plant. The rescheduled in-service date for WR2 is Sept. 1, 2016. The rescheduled in-service date for WR1 is July 17, 2017.
Consequently, the AESO applied to the commission to amend the approved project need by moving certain transmission developments between the WR1 and WR2 interconnection projects and rescinding the need for other previously approved facilities. The construction of the Elkwater 264S substation would be moved to the WR2 interconnection project and subsequent modifications to the Elkwater 264S substation would be moved to the WR1 interconnection project. Facilities that were required in 2013 to facilitate connecting the WR1 wind power plant to the electric system are no longer required because the 240-kV transmission lines 1034L/1035L and 964L/983L have since been energized.
In order to accommodate the new in-service dates for the WR1 and WR2 wind power plants, construction of the proposed facilities is scheduled to commence by April 4, 2016, the commission noted.
Originally, the capacity of these projects was to be 200 MW each. NaturEner subsequently proposed a change in turbines which resulted in a capacity of 210 MW each. More recently, NaturEner requested an in-service date of July 2017 for Wild Rose 1 and September 2016 for Wild Rose 2 and advised the AESO that the capacity of Wild Rose 2 was reduced to 189 MW, said the AESO in its May 29 application for this approval.
The NaturEner website shows these projects as:
- Wild Rose 1 – 210 MW, consisting of Alstom ECO 110 3-MW turbines.
- Wild Rose 2 – 189 MW, also consisting of Alstom ECO 110 3-MW turbines.
