Supply Chain Sustainability

Ameren’s suppliers and business partners play an important role in helping us create a more sustainable energy future. Our goal is to build a supply chain that supports Ameren’s sustainability priorities. This includes defining a strategy to integrate our supply chain platform with corporate Sustainability/ESG strategy and collaborating with suppliers and business partners to identify ways to operate more sustainably.

Essential to this approach is partnering with suppliers who are responsibly managing the environmental, social and economic impacts of their business. We do this by ensuring the goods and services we purchase, including office products, are sustainable; socio-economic issues, such as inequality, are addressed; and working conditions of suppliers' employees are acceptable. 

In addition, Ameren is keeping 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.

Supply Chain Monitoring and Supplier Certifications

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 3,926 suppliers are in 48 states. The total spend with suppliers was more than $3 billion in 2021. Ameren managed strategic supplier relationships and expectations through more than 47 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.

Our procurement department evaluates suppliers based on specific criteria (i.e., safety, quality, supplier diversity) both during the initial screening and contract renewal. This includes monitoring strategic suppliers for Environmental Management Systems that have received external certifications (i.e., according to the ISO 14001 standards).

Emphasizing the importance of contracting with women-owned, veteran-owned and minority-owned firms, in 2021 Ameren spent nearly $900 million with diverse suppliers and earned the Edison Electric Institute Excellence Award for Supplier Diversity. Ameren encourages suppliers to have the same commitment in their use of materials and services from their base of diverse suppliers and contractors.
