Major accomplishments to date

Since we were formed in 2001 as a utility solely focused
on electric transmission, we have:

• upgraded more than 1,824 miles of transmission line,
• improved 165 electric substations and
• built 48 new transmission lines (600 miles).

A more reliable transmission system has enabled us to:

• reliably deliver electricity to customers in Wisconsin, Michigan and Illinois at all
  hours of the year including peak demand hours,
• maintain top reliability performance,
• support approximately 1,200 MW of new peak electric usage,
• connect 6,048 MW of new generation at 24 sites,
• connect more than 630 MW of wind generation,
• resolve problems in 19 specific areas to move power into or through our system.
• • Arrowhead-Weston (Northwestern Wisconsin)
  • Blackhawk-Colley Road (Rock County, Wis.)
  • Christiana-Kegonsa (Dane County, Wis.)

We have made progress by actively seeking input and making our plans and proposals public. To date, ATC has:

• held dozens of major public planning and siting meetings, and
• participated in thousands of interactive local, state and industry discussions, both giving and receiving information to carry out our duties and responsibilities.
