Second GTCC unit completed at Mankato Energy Center in Minnesota

A Minnesota gas-fired power plant currently owned by a subsidiary of Southern Co. has completed its expansion.

Southern Power announced that the 345 MW, second combined cycle unit at the Mankato Energy Center is ready for commercial operation. The combination of two gas-fired units brings Mankato’s capacity to 760 MW.

“The completion of the Mankato Energy Center expansion represents an incredible accomplishment for our employees and partners involved with the project,” said Southern Power President Bill Grantham. “Together, the team applied their considerable skills and expertise to make the project a success while demonstrating a strong commitment to safety.”

Southern Power is selling the Mankato Energy Center to Xcel Energy for $650 million. The transaction is still waiting for regulatory approval and should be closed by the third quarter.

Xcel has been Mankato’s customer under long-term power purchase agreements.

Southern acquired the facility in October 2016. It was Georgia-based utility’s first generating assets within the Midcontinent Independent System Operator (MISO).
