McDermott announces substantial completion of 980MW St. Charles Power Station in US


McDermott has announced substantial completion of 980MW St. Charles Power Station in Montz, Louisiana, US for Entergy Louisiana, a subsidiary of Entergy Corporation.

The $870m (£690.4m) combined-cycle gas power station has been turned over to the owner, Entergy, and has begun commercial operations.

McDermott North, Central and South America senior vice-president Mark Coscio said: "McDermott is pleased to announce that the St. Charles Power Station project is substantially completed and that Entergy Louisiana has already begun commercial operations.

"We were able to deliver this project ahead of schedule and on budget for Entergy Louisiana, and we continue to work with Entergy companies on two other projects: Lake Charles Power Station for Entergy Louisiana and Montgomery County Power Station for Entergy Texas."

Designed to reduce CO2 emissions on average about 40% below Entergy's older natural gas-fired units, the St. Charles Power Station is one of six projects to be undertaken across Entergy’s service area over the next three years.

The power plant features two M501GAC gas turbines, two Nooter Eriksen heat recovery steam generators (HRSGs) and a Toshiba steam turbine and generator (STG) in 2×1 CCGT configuration.

It is equipped to generate electricity required to meet the power needs of approximately 675,000 typical Louisiana households.

Earlier, Entergy Louisiana president and CEO Phillip May said: “The St. Charles Power Station will supply reliable, clean energy to customers to help support the tremendous growth Louisiana is experiencing.

“This combined-cycle plant is one part of our transformation to cleaner, more efficient generation. Replacing older, less efficient plants with new, cleaner natural gas units will improve system reliability, reduce environmental impacts and produce substantial customer savings over the long term.”

The project, which employed 955 people at peak during construction phase, also forms a part of Entergy's broader plan to modernise and transform the existing generation fleet.

Entergy Louisiana employs 31 people at the power plant to support its operations.
