CDM Smith to Begin Construction on the AES Petersburg Coal to Gas Conversions
PETERSBURG, Ind. — CDM Smith received full notice to proceed from the Babcock & Wilcox Company (B&W), the prime contractor for the coal to gas conversions of Fortune 500 global energy company AES Corporation. The team will mobilize to the generating station to begin construction.
CDM Smith was selected last year to provide engineering, procurement and construction services for the balance of the plant system. This initial phase included an issue for construction drawings and procuring all the long-lead equipment for the coal to gas conversions. In successfully completing the first design phase and reaching the agreement on the full notice to proceed contract, the team will progress into construction of core process modifications at the generating station.
The goal of the coal to gas conversions is to deliver cleaner, more efficient and cost-effective energy solutions to AES’s customers. Natural gas will account for approximately 70% of the plant’s resource mix once the Petersburg conversions are complete, and the full plant conversions are to be completed by the end of 2026. Upon the project’s completion, AES Indiana will become the first Indiana investor-owned utility to cease burning coal.
