    Dec 8, 2022 Update to materials:

    Following the virtual Oct. 20th, 2022, Transmission System Projects Overview information session, the AESO identified two charts showing Transmission Rate Projection (TRP) information weren’t reflecting the latest information. Charts shown on slide 13 and slide 37 were prepared using older TRP information. We have since updated the charts with the latest TRP information, and the new charts are now included in the updated presentation found in the Materials section on the right-hand side of the page.
