A newly released study by HR&A Advisors finds that Ameren’s operations in Missouri and Illinois drive more than $20.7 billion in annual economic output. The analysis incorporates direct spending on payroll, capital equipment, supplier services and the cascading effect of those expenditures on housing, retail and other sectors. Every dollar of Ameren’s regional investment supports additional leading-wage jobs, disposable income and tax revenue in the bi-state area.

Ameren’s presence sustains 55,200 jobs across its service territory and channels $2.2 billion in purchases to in-state vendors and suppliers. The company’s tax payments to state and local governments total $920 million annually. Ameren also directs $10.6 million in philanthropic grants to address critical community needs, underscoring its role as a major economic steward for more than 3.4 million utility customers.

Through technical assistance to businesses seeking to establish or expand operations, Ameren facilitated 73 economic development projects in 2025. These initiatives sparked $3.56 billion in private capital investment and created 3,728 new jobs. Notable projects include expansions by a global cable systems manufacturer investing $63.8 million in southern Illinois and a $500 million copper products plant that will add 700 full-time positions in the St. Louis metro region.

Ameren’s ongoing cost-management and operational-streamlining initiatives are helping mitigate upward pressures on energy costs. By focusing on reliability and resiliency upgrades to the power grid, the company has been able to keep rates as low as feasible, thereby boosting disposable incomes for residential and business customers and further amplifying the broader economic impact across Missouri and Illinois.
