Watch an AUC hearing


The Alberta Utilities Commission will be holding a hearing to consider a power plant amendment application and submissions received in Proceeding 27216. The AUC issued a notice of hearing on August 15, 2022. 

Concord Coaldale GP2 Ltd. has applied to amend the Coaldale Solar Project by adding a 21‑megawatt battery energy storage system. The Coaldale Solar Project, currently under construction, is located in the northwest quarter of Section 7, Township 10, Range 19, west of the Fourth Meridian, and the southeast quarter of Section 12, Township 10, Range 20, west of the Fourth Meridian, approximately seven kilometres north of the town of Coaldale.

The battery energy storage system would be wholly located within the existing fenceline of the Coaldale Solar Project. The battery energy storage system would charge primarily from on-site solar production and discharge to the FortisAlberta Inc. distribution system, with the ability to also charge from the FortisAlberta distribution system. The application was filed under the Hydro and Electric Energy Act.

Further information about the proceeding is available through the AUC’s eFiling System under Proceeding 27216.
