Entergy Mississippi was unveiling Thursday plans for a $25 million operations complex in Jackson.

The company plans to move its corporate transmission headquarters to a new building off Interstate 220 near existing operations, creating a campus-style complex for employees.

Entergy Mississippi’s President and CEO Carolyn Shanks said the location is already home to the company’s nuclear operations, as well as its storm-response command and training center.

Shanks said once completed, there will be 500 employees at the site.

The transmission headquarters will be responsible for managing the delivery of electricity throughout the corporation’s four-state service area.

Officials expect the facility to be completed in 2009.

In addition to the transmission facility, the company also will expand its nuclear headquarters site there to consolidate the management of Entergy’s 11 nuclear systems.

Entergy’s nuclear expansion and the new transmission headquarters are the latest in a series of recent energy projects announced in the state. Others have included Gulf Coast oil industry improvements, an ethanol plant in Vicksburg and the Richton Salt Dome, which will become a federal strategic petroleum reserve.
