Our progress
As a public utility, we exist to serve. At ATC, we’re focused on delivering sustained value to our customers, stakeholders and the communities we serve. Building, maintaining and protecting the electric grid enables continual reliable, affordable, sustainable, and secure energy for customers and communities.
ATC’s asset management program is focused on the life‑cycle management of our assets to ensure these assets perform the required function in a safe, reliable and sustainable manner while also managing 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 high-voltage 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. In 2024, we had an exceptional year for reliability performance, with record numbers in uptime, outage response times and electric grid stability.
Our single‑focus, transmission‑only business model has produced significant results for our customers. In this evolving energy landscape, we continue to provide exceptional and reliable service to the customers and communities we serve.
Since the publication of the 2023 10-Year Assessment, we have:
- Made improvements to 13 substations
- Upgraded or rebuilt approximately 12 transmission lines
- Signed 13 new generator interconnection agreements as part of MISO’s 2020 Interconnection Queue, which includes approximately 2,150 megawatts of renewable generation
- Supported our local distribution customers through our Load Interconnection Request (LIRF) program for numerous projects, including:
- Interconnection of new loads
- Replacement of aging distribution infrastructure
- Integration of Distributed Energy Resources (DERs)
