Reason for Variance This project was submitted in September 2024 as a Planned & Advanced (P&A) project, for $2,079,681, and was subsequently withdrawn as the Company was able to secure additional NRCan funding which resulted in the total p...

AI summary The project, initially submitted as a P&A project in September 2024, was withdrawn after securing additional NRCan funding, reducing the cost below $1 million. It was listed in the 2025 ACE Plan as a carryover project. The project estimate increased from $968,222 to $2,148,364 due to the inclusion of additional sensors on the NB Import Transmission Line, which presented greater geographical and terrain challenges.
