Ameren Missouri Invests in Infrastructure to Power Pfizer Expansion

The Chesterfield R&D facility at 825 Chesterfield Parkway West develops manufacturing processes, dosage forms and analytics for clinical and commercial purposes in areas such as oncology, rare diseases, internal medicine, inflammation and immunology, and vaccines. Pfizer's R&D facility also works to develop innovative gene therapy manufacturing technologies and solutions. It features flexible lab layouts and open floor plans that Pfizer hopes will boost collaboration among its engineers, biologists, chemists and pharmacy specialists.

Pfizer’s commitment to the region means 450 employees, including 80 new employees working in STEM positions, get to make St. Louis their home.

Ameren offered full service support for the expansion project in partnership with St. Louis Economic Development Partnership and the state of Missouri and helped to facilitate innovative utility infrastructure solutions in accordance with unique project characteristics and the investment of new infrastructure in accordance with the design-build construction approach.

The new Chesterfield site, which Pfizer owns, was a consolidation of Pfizer’s locations at the Chesterfield Village Research Center and Missouri Research Park in St. Charles County. Pfizer previously leased space at the Chesterfield Village Research Center from Bayer.
