Our progress
As a public utility, we exist to serve. At ATC, we are focused on delivering sustained value to our customers, stakeholders, and the communities we serve. By building, maintaining and protecting the electric grid, we help deliver reliable, affordable, sustainable, and secure energy for customers and communities.
ATC’s asset management program is focused on the lifecycle management of our assets to ensure they perform their intended function in a safe, reliable and sustainable manner while 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 public and worker safety, regulatory compliance, asset condition, reliability, and operational performance. ATC’s high-voltage transmission lines consistently achieve higher reliability performance than our industry peers in all voltage classes, thanks to our dedicated asset management efforts. In 2026, we achieved exceptional reliability performance, with record results in uptime, outage response times and electric grid stability.
Our single-focus, transmission-only business model continues to deliver value for our customers. As the energy landscape continues to evolve, we remain focused on providing reliable service to the customers and communities we serve.
Since the publication of the 2025 10-Year Assessment, we have:
- Made improvements to 18 substations
- Upgraded or rebuilt approximately 11 transmission lines
- Signed 18 new generator interconnection agreements as part of MISO’s 2021 Interconnection Queue, which includes approximately 2,423 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)
