As we continue to use our system-wide planning process to effectively and economically improve reliability, more emphasis is being placed on the need to efficiently maintain and upgrade our older assets. Our asset management program is focused on the life-cycle management of transmission assets. The objective is to ensure assets perform the required function in a sustainable manner while managing life-cycle cost. Coordination of design, commissioning, operation, maintenance and replacement strategy is crucial to developing the replacement strategy of the asset life cycle. Asset renewal is driven by public and worker safety, regulatory compliance, reliability and operational performance.
Due in large part to our asset management efforts, in 2016 we achieved top decile performance for components operating at 69-kV and between 100- and 161-kV, along with top quartile for the 345- to 500-kV voltage classes.
Our single-focus, transmission-only business model has produced significant results for our customers over the years.
Over the past ten years, we have:
- Upgraded more than875miles of transmission line,
- improved 98 electric substations,
- built 24 new transmission lines (436 miles),
- connected 2,700 MW of new generation at 16 sites,
– Including 680 MW of renewable generation at
- increased import and export capability, and
- improved transmission reliability.
