American Transmission Co. publishes annual 10-Year Transmission System Assessment

Connecting to renewable generation continues driving the need for new, updated transmission infrastructure

PEWAUKEE, Wis. – American Transmission Co.’s new 10-year plan to address the need for electric grid improvements is driven by an increase in renewable generation projects in addition to required asset maintenance improvements.

“Since the time ATC was formed 20 years ago, our aim has been to consistently achieve the highest standards in electric reliability, efficiency and safety,” said Andy Dolan, vice president of system planning. “The interconnection requests we’ve seen over the last year for renewable generation developments in our footprint is unprecedented. In response, our long-range planning efforts are transforming today’s network for tomorrow’s sustainable energy future.”

Specifically, the plan calls for expenditures of $2.2 billion in asset maintenance, $0.2 billion in regional Multi-Benefits Projects, $0.6 billion in network projects and between $0.5 billion and $1.2 billion in other capital expenditures.

“While we’re investing in a grid that aligns with new technologies and generation resources, 50% of our capital projects are also driven by aging infrastructure,” said Jim Vespalec, director of asset planning and engineering. “Significant investments in our existing infrastructure are required to address deteriorating wooden poles and substation equipment initially installed decades ago that is approaching end-of-life. Additionally, new fiber optic wire upgrades and installations also help our operators address unplanned and planned outages and more reliably monitor the status of our grid.”
