Since 2001, ATC’s top priority is maintaining a safe, reliable transmission system. As the industry evolves, we strive to make electricity a great value for our customers by strengthening the grid – which enhances their participation in the wholesale energy market. We’re driven to make smart investments in our aging transmission assets while analyzing industry trends that identify new reliability improvement projects.
ATC’s asset management program is focused on the life‑cycle management of transmission assets. Our objective is to ensure these assets perform the required function efficiently and reliably in a sustainable manner while managing life‑cycle costs. We collaborate on the design, commissioning, operation and maintenance of these assets, which is crucial to developing a comprehensive system plan and replacement strategy.
Our asset renewal process focuses on aspects of public and worker safety, regulatory compliance, reliability condition and operational performance. ATC’s transmission lines consistently achieve better reliability performance than those of our industry peers in all voltage classes, which is primarily due to our asset management efforts.
Our single‑focus, transmission‑only business model has produced significant results for our customers, and we strive to continue providing exceptional service for them in the years to come.
