Power Profile: Michael Moehn
Michael Moehn currently serves as Ameren's senior executive vice president and CFO. He is also the president of Ameren Services.
For nearly 25 years, Michael Moehn has focused his Ameren career around a simple principle: service to customers, communities and the employees who power the company’s work. That foundation has guided him from his first role in finance to his current position as senior executive vice president and chief financial officer.
Beginning Jan. 1, he will transition to serve as the group president of the newly created Ameren Utilities, which brings Ameren Missouri, Ameren Illinois and Ameren Transmission Company under unified leadership to strengthen coordination across the organization.
Moehn joined Ameren in 2000 and was immediately struck by the criticality of the work.
“It’s an industry that touches people every single day in some way,” he said.
He also found that the company’s culture of hard work and servant leadership reflected the values he grew up with. Roles in finance, planning, strategy and operations broadened his understanding of how interconnected the energy business is and how closely the customer experience is tied to every decision. The variety and purpose of the work continue to motivate him.
“It’s a fascinating industry,” he said.
In his new role leading Ameren Utilities, Moehn plans to continue emphasizing alignment and consistency across the operating companies. He believes customers in both Missouri and Illinois benefit when expectations and practices are clear and coordinated. Strong internal standards, he said, help teams focus on what matters most for the communities they serve.
The coming years will bring significant transformation across the energy sector. Ameren is investing in reliability and natural gas generation in the near term while studying potential new nuclear options and advancing work in batteries, customer-focused technologies and grid modernization. The scale of future investment, he said, is unlike anything the company has seen in decades.
“We’re at an inflection point that we haven’t seen in this industry for 20 years,” he said. “We have a growth opportunity in front of us over the next five to 10 years to make smart investments on behalf of our customers that will be foundational and allow the communities we serve to thrive.”
As CFO, Moehn helps position Ameren to bolster the grid with long-term investments that benefit customers while balancing affordability for customers. The company is entering a period when investment decisions carry even greater weight, since new technologies and generation resources require years of planning. That work depends on close coordination across finance, operations and regulatory teams, along with a clear understanding of how each project will affect customers over time.
“Managing our balance sheet conservatively allows us to get the lowest interest rates,” he said, “and therefore there’s greater cost savings back to customers.”
Looking ahead, he sees Ameren’s evolving workforce as central to the company’s future. The scale and complexity of the system create opportunities for employees to build diverse and long-term careers. It is not unusual for people to move between departments or across the Missouri and Illinois operations as they advance, gaining experience in engineering, finance, planning, operations, skilled trades and more.
For Moehn, career development is most successful when employees are encouraged to explore new pathways and when leaders create the environment to support that growth.
"It's not just a job in my perspective. I think of it as a career, which is focused on the long term. Careers are a lifelong journey and a two-way street that focus on skill development and personal fulfillment."
He also praised the work of Ameren's frontline and plant employees who keep the company's infrastructure operating safely and reliably.
"They are the best at what they do," he said.
As Ameren moves toward major capital investments, Moehn said his leadership approach is shaped by the need to stay focused on what truly moves the company forward. Large projects, shifting customer expectations and evolving technologies all compete for attention. He believes disciplined prioritization is essential for keeping the organization aligned and ensuring resources go to the areas that deliver the greatest long-term benefit for customers.
“If everything’s important, nothing’s important,” he said.
That philosophy is rooted in how he grew up. His parents ran a small business, and their example taught him the value of discipline and staying grounded regardless of circumstance. Those early lessons have guided him throughout his career and continue to influence how he approaches challenges and supports his teams.
“There’s just no substitute for hard work,” he said.
Family is an anchor in his life. Moehn and his wife have been married for 31 years, and he credits her high standards and grounding presence with shaping the way he approaches both work and leadership. Their son works in Wisconsin, and their daughter is completing her collegiate swimming career at the University of Pennsylvania before beginning work in investment banking. Much of their family time has been spent traveling to swim meets, something he describes as a joy to experience together.
Outside of work and family, personal well-being is another priority. Moehn is an avid runner and sees exercise as part of his leadership toolkit.
“It’s an investment in me,” he said. “It allows me to be a better person, to be a better leader.”
