ITC's operating practices are rooted in safety and reliability – two pillars of excellence at the foundation of our transmission-only model.

Our independent model provides a singular focus on transmission-system performance, planning and operations. ITC's financial and strategic efforts center on delivering a reliable and efficient electric transmission grid to meet the needs of the customers we serve.

ITC invests in transmission infrastructure to:

  • Improve system reliability
  • Expand access to energy markets
  • Lower the overall cost of delivered energy
  • Allow new generating resources to interconnect to the power grid
  • Support national energy independence and security

We track our operational performance alongside industry peers through participation in the annual SGS Benchmarking Study. The most recent study showed that our Michigan subsidiaries ranked within the top 10 percent of best performers with respect to sustained outages. We also saw some significant improvements in system performance and restoration at ITC Midwest in 2011, with the fewest sustained outages recorded since we have owned the system. Trending data shows that the longer we own a system, the better its performance.

Our capital investment and maintenance plans drive this solid performance. The graph at left shows that ITC invests far more in preventive maintenance than in reactive maintenance. Basically, we are fixing things before they can break. This results in improved safety and reliability and supports our operational excellence objectives.
