Duke Energy on Thursday announced several executive changes, including the appointment of a new chief ethics and compliance officer and a new chief risk officer. The changes are effective Dec. 1.

Melissa Feldmeier, currently deputy general counsel, will be named vice president and chief ethics and compliance officer. Feldmeier has been a part of Duke Energy’s legal team since 2001.

“She recently provided legal counsel on human resources matters, serving as a trusted advisor to many senior leaders and distinguishing herself as a strong advocate to oversee Duke Energy’s ethics program, data privacy, and compliance standards,” Duke Energy said in a statement.

Feldmeier will assume the role from Keith Butler, who was serving as acting chief ethics and compliance officer in addition to his current role as senior vice president, global risk management and insurance, chief risk officer. Effective Dec. 1, Butler will become senior vice president and chief security officer.

Additionally, Duke Energy announced the appointment of Katie Aittola as vice president, global risk management and insurance and chief risk officer. Aittola, who is currently managing director of supply chain risk, continuous improvement and governance, joined Duke Energy in 2009. “Her background includes more than a decade in corporate development, financial planning and analysis and supply chain, which will serve her well as she leads the team responsible for identifying, evaluating, and mitigating risks across the company.”
