Central Iowa Power Cooperative's executive vice president and CEO, Dennis Murdock, will retire effective Sept. 30, the organization announced. Murdock has dedicated more than 50 years to CIPCO, including more than 28 years in his current role.

The Des Moines-based cooperative's board of directors has appointed Bill Cherrier, currently chief planning and finance officer at Colorado Springs Utilities in Colorado, as his replacement. CIPCO is Iowa's largest cooperative energy provider, serving 13 electric cooperatives and associations spanning 58 of Iowa's 99 counties. 

"Dennis has skillfully directed the company to outstanding growth and success during his tenure, leading a talented organization in the delivery of safe, reliable and affordable energy for Iowans," board President Paul Heineman said in a release. 

Among his accomplishments, Murdock led CIPCO through the acquisition of wind generation and the launch of the state's largest utility-scale solar system. During his tenure, CIPCO established the Iowa Area Development Group and CIPCO's wholly owned investment subsidiary, CMA Ventures.

Cherrier has 35 years of experience in the utility industry, most recently as the chief planning and finance officer at Colorado Springs Utilities. His experience also includes time in Iowa as manager of finance and development with Alliant Energy and generation business operations at IES Industries in Cedar Rapids.
