Our goal is to build a supply chain that supports Ameren’s sustainability priorities. Essential to this approach is partnering with suppliers who are responsibly managing the environmental, social and economic impacts of their business:

• Goods and services we purchase are sustainable
• Socio-economic issues, such as inequality, are addressed
• Working conditions of suppliers' employees are acceptable

At the same time, Ameren keeps our downstream impacts in mind. Our Investment Recovery Program responsibly coordinates the selling and/or divestment of scrap, surplus, substation and distribution transformers and oil-filled electrical equipment, transmission material, energy center equipment, retired fleet and other assets, as part of our sustainability priorities.

Ameren views its suppliers as strategic partners and expects that all suppliers, their subcontractors and personnel performing work for Ameren or any of its subsidiaries, conduct themselves in a manner consistent with our values and mission. Ameren’s supply chain includes products and services to support operations, fuel supply (including natural gas and nuclear) and purchase power.

Ameren’s 3,615 suppliers are in 49 states. Some Ameren suppliers contract with multiple lines of Ameren businesses and are counted in multiple categories. The total spend with suppliers was more than $3.4 billion in 2022. Ameren managed strategic supplier relationships and expectations through more than 56 scorecards and executive business reviews to measure performance and develop corrective action plans. Some areas of focus were safety, quality, supplier diversity, on-time delivery, etc. In addition, executive meetings were conducted with strategic suppliers and Ameren senior leadership.
