Ameren has announced several initiatives focused on customer support and long-term energy planning. The company increased funding by $10 million for customer assistance programs in Missouri and Illinois, targeting residential and small-business energy bills, weatherization, and support for veterans.

In conjunction with its updated 20-year Integrated Resource Plan, which includes a mix of natural gas, solar, wind, battery storage, and nuclear generation, Ameren Missouri has begun physical infrastructure improvements. This includes upgrading the Moscow Mills substation with new transformers to improve reliability and support local growth. Additionally, the company has applied for approval to construct the Katy Substation near Columbia to enhance grid segmentation and prevent widespread outages.
