Black & Veatch said June 18 that it has been selected to provide engineering services for the installation of a $400m combined cycle gas power unit for the Grand River Dam Authority (GRDA) in Oklahoma.
The Mitsubishi Heavy Industries J-series combustion turbine to be used in this project will be the first installed in the Western Hemisphere. This advanced technology has the potential to make the plant the most efficient combined cycle generator in the United States, Black & Veatch noted.
Black & Veatch will serve as Owner’s Engineer, providing permitting and engineering, construction and procurement-related services. The new Unit 3 at the Grand River Energy Center will be able to produce 495 MW. Unit 3 is being built alongside two existing coal-fired units about 35 miles east of Tulsa, Okla.
“This project is a milestone for the GRDA by diversifying our generation portfolio while leveraging Oklahoma’s natural gas reserves,” said Dan Sullivan, GRDA Chief Executive Officer/Director of Investments. “Black & Veatch was selected following a vigorous evaluation process in which it was determined they could best meet our objectives. In addition, the company has a long history with GRDA in delivering high-quality engineering services and counsel on industry issues.”
“The new gas-fired unit will further position the GRDA as a leader in deploying the latest technology in power generation,” said Dean Oskvig, President and CEO of Black & Veatch’s Energy business.
Project completion is scheduled in the spring of 2017. It includes a new substation being designed by Black & Veatch. Black & Veatch is also providing conceptual engineering and procurement services for the combustion turbine, steam turbine, heat recovery steam generator and step-up transformers.
The company is also providing engineering services for retrofitting emissions controls on the coal-fired Unit 2. Completion is scheduled for the spring of 2016. The Unit 2 retrofit work will include the conversion of the existing electrostatic precipitator to a fabric filter, addition of an activated carbon injection system, upgrading the induced draft fans, and associated balance of plant modifications. GRDA has been considering whether to retire, refuel to natural gas or retrofit with emissions controls the coal-fired Unit 1.
