Additional Generation and Transmission Resources

In January 2024, Amazon Web Services announced its plan to invest in two data centers located in Madison County, Mississippi.  In March 2024, Entergy Mississippi executed a large customer supply and service agreement to serve the two data centers.  Entergy Mississippi will need generation and transmission resources to reliably serve all Entergy Mississippi customers, including the data centers.  The large customer supply and service agreement also contains provisions which cover Entergy Mississippi’s incremental investment costs in the event of early termination.  In May 2024 the MPSC approved Entergy Mississippi’s revisions to its formula rate plan to comply with state legislation passed in January 2024 allowing Entergy Mississippi to make interim rate adjustments, including the collection of a return on construction-work-in-process on a cash basis, to recover the non-fuel related annual ownership cost of certain facilities that directly or indirectly provide service to customers who own certain data processing center projects as specified in the legislation.  Entergy Mississippi anticipates recovering the incremental cost to serve the customer through the revenues it expects to collect under the large customer supply and service agreement.

In February 2025, Entergy Mississippi entered into a new large customer supply and service agreement with a customer.  The planned capital investment estimates for 2025-2027, shown above, include amounts related to the generation and transmission resources needed to reliably serve all Entergy Mississippi customers.

Delta Blues Advanced Power Station

In September 2024, Entergy Mississippi announced plans to construct, own, and operate the Delta Blues Advanced Power Station, a 754 MW combined-cycle combustion turbine facility, to be located in Washington County, Mississippi.  The facility will primarily be powered by natural gas, and it will also be enabled for future carbon capture and storage and for hydrogen co-firing optionality.  The Delta Blues Advanced Power Station will cost an estimated $1.2 billion.  State legislation passed in January 2024 provides for the pre-certification of construction for certain types of facilities that directly or indirectly provide electric service to customers who own certain data processing center projects as specified in the legislation.  Construction of the Delta Blues Advanced Power Station qualifies under this legislation for pre-certification.
