Wisconsin-based ATC has identified billions of dollars worth of electric grid improvements that are needed over the next decade throughout the company’s service area, according to its just-published 10-year assessment plan.

Specifically, the plan outlines needed investments of:

• $1.8 billion for projects to meet system planning criteria (network projects);
• $1.4 billion in regional multi-benefit projects (including the Midcontinent Independent System Operator [MISO] Long-Range Transmission Planning projects);
• $4.0 billion to maintain reliable infrastructure (asset renewal);
• $1.5 billion for projects that support economic growth in the ATC service area (distribution-to-transmission interconnection requests); and
• Up to $2.2 billion in other capital expenditures (generation-to-transmission interconnection requests).

Additionally, ATC expects an increased need for electric grid infrastructure investment, based mainly on the evolving energy landscape, integration of renewable generation, and large new load requests, according to the plan.
