Link to Decision Summarized

Gas – Facilities


Tidewater Midstream and Infrastructure Ltd. (“Tidewater”) requested approval to add two Solar Titan 130 natural gas-fired generators, each rated at 17.7 MW to supply the expansion of the Pipestone Sour Gas Plant (“Pipestone Gas Plant”) located in the County of Grand Prairie No. 1 (the “Pipestone Power Plant”). After the proposed power plant expansion, the total capability of the Pipestone Power Plant would be 68 MW. The Pipestone Power Plant would continue to supply only the Pipestone Gas Plant, be electrically isolated from the Alberta Interconnected Electric System, and would be located within the footprint of the existing Pipestone Gas Plant on land already cleared for industrial purposes.


The AUC determined that the application was in the public interest as required under s. 17 Alberta Utilities Commission Act. Pursuant to ss. 11 and 19 of the HEEA, the AUC approved the application from Tidewater to alter and operate the Pipestone Power Plant.
