    North Lethbridge 370S Substation Modification Project

    Recent studies have shown the existing transmission system in the North Lethbridge area needs to be reconfigured to continue to provide a reliable supply of electricity to the City of Lethbridge. The AESO is proposing modifications to the existing North Lethbridge 370S substation, which include the addition of one 138 (kilovolt) kV circuit breaker. Circuit breakers are electrical switches inside a substation that protect substation equipment. Minor modifications of associated equipment are also required.
