Plant Watson unit 3 retired


Mississippi Power announced today that unit 3 at Plant Watson in Gulfport has been retired and is no longer available for dispatch.

“Mississippi Power customers have received power from this unit for more than 50 years,” Vice President and Senior Production Officer Allen Reaves said. “However, it’s no longer economically feasible to keep the unit online due to age and efficiency. The best decision for the company, and our customers, is to retire this unit from service.”

Unit 3, which produces 113 MW of power, began operating in 1962 and is 55 years old.

Two years ago, units 1 and 2, which produced a combined 150 MW of power, were retired.

The retirement of the unit will have no impact on Generation employee headcount.

When the unit entered service, then-Mississippi Power President Jack Watson was quoted in the Aug. 1962 edition of Power Lines as saying that the new unit, “reflects our continuing construction and improvement program designed to keep well ahead of the electric power requirements of our customers.”
