The Alberta Utilities Commission will be taking comment until Aug. 7 on a recent application from the Alberta Electric System Operator for approval of the need to amend the approved interconnections for NaturEner Energy Canada Inc.’s Wild Rose 1 and Wild Rose 2 wind power plants as a result of a change to the in-service dates for the two plants.
The Wild Rose 2 plant will now be in-service before the Wild Rose 1 plant.
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.
AltaLink Management Ltd. is seeking under separate applications approvals to construct the facilities to meet the amended need identified by the Alberta Electric System Operator. The proposed project would connect the Wild Rose 1 and Wild Rose 2 wind plants to the Alberta Interconnected Electric System. The original applications were comprised of two geographically distinct developments referred to as East Palliser South and East Palliser North. The current applications seek approval to:
For East Palliser South:
- Construct the Elkwater 264S switching substation consisting of six (instead of nine) 240-kV circuit breakers at a new location north of the approved location. This includes reducing the size of the fenced area to 60 meters x 105 meters while increasing the total substation property area to 240 meters x 220 meters.
- Construct NaturEner Energy Canada’s Eagle Butte 274S substation north and west of the approved location.
- Construct the approved 240-kV transmission line 1076L from Elkwater 264S switching substation to Eagle Butte 274S substation in a north-south alignment (instead of an east-west alignment) over the shared fence.
- Stipulate a later completion date for the already approved 36 kilometer-long, single-circuit, 240-kV transmission line, designated as 978L, between Wild Rose 1 547S substation and Elkwater 264S substation.
- Extend previously approved transmission line 978L by 250 meters in the southwest corner of NE 12-10-5-W4M, to connect to the east side of the Elkwater 264S substation (instead of the south side). f) Construct a new, approximately 55 metre long, double-circuit 240-kV transmission line to connect existing transmission line 938L to the west side of the Elkwater 264S substation with an in/out configuration (and re-designate the portion of transmission line 938L from Elkwater 264S substation to Bowmanton 544S substation as 1074L).
- Construct a new access road south from Township Road 102 to the Elkwater 274S substation.
- Alter Bowmanton 244S substation by adding one 240-kV, 45 megavolt-ampere reactive shunt reactor on the west side of the substation site (instead of on the east side) and one (instead of three) 240-kV circuit breaker.
For East Palliser North:
Rescind previously issued permits and licences for facilities that will no longer be needed as a result of the changed in-service dates. This includes:
- Not adding one 240-kilovolt (kV) circuit breaker to the existing Cypress 562S substation;
- Not upgrading a portion of existing transmission line 668L; and
- Not constructing a new transmission line, designated 1009L, from the Bowmanton 244S substation to the Cypress 562S substation.
