Central Iowa Power Cooperative currently owns and maintains nearly 2,000 miles of transmission lines, delivering power to over 300-member substation delivery points through CIPCO’s owned and contracted facilities.
The New-To-Replace-Old (NTRO) program began in 1986 to rebuild CIPCO’s aging 34.5kV transmission lines as they reached end-of-life. The program was expanded later to include 69kV, 115kV and the 161kV lines. In total, CIPCO has rebuilt 1,100 miles of its original first-generation lines under the NTRO programs.
A top-notch transmission system is only as good as its substation delivery points. CIPCO prides itself on sound operating and maintenance programs to ensure our power supply system sustains the highest degree of reliability that our Member-owners expect and deserve.
With office locations in Des Moines and Cedar Rapids and dispatch and transmission facilities in Creston and Wilton, CIPCO's strategic locations ensure broad response capabilities across 300 miles and 58 of Iowa's 99 counties. CIPCO dispatch operations facilitate quick, 24/7 responses during storms and heavy (peak) load situations, as well as outages and general monitoring of the entire transmission system.
