On behalf of our client, we conducted a study on how increased use of electricity in agricultural production might affect the rural distribution system in Alberta. We also analyzed the technical impact to the single-phase rural distribution system and associated costs for end-consumers.
The study was comprised of two scopes of work. In Scope 1, we identified the potential electrification that could occur on rural farms. Our team segmented Alberta's agricultural industry into regional and sector categories to determine the numbers of farms in each type of category and identified counts of electrification-eligible equipment present.
To validate the findings, we conducted external engagement sessions with agricultural industry groups and the technical working committee. We then created a per farm per kilowatt electrification profile. By identifying three electrification scenarios—low, high and peak—our team was able to determine varying degrees of electrification of the eligible equipment under each scenario.
In Scope 2, we obtained representative distribution feeder models and applied the additional load per farm as identified in Scope 1 to test the impact and failure rate of the existing system. This us a picture of which distribution assets and feeders had failures that arose by adding the electrification load, and when the tipping point in technical capacity of the single-phase system occurred. Our team then identified mitigation measures and developed capital replacement cost estimates that may be required to enhance the distribution system.
This study provides a crucial first step to inform provincial distributors around future planning for rural and agricultural electrification. Ultimately, it will serve as a foundational document supporting Alberta Utility Commission (AUC) proceedings and assisting policymakers in decarbonization initiatives and decision-making.
