Engineering and construction company The Shaw Group has revealed that two of its business units will carry out retrofit services on a Duke power station after it was awarded an engineering, procurement and construction contract worth half a billion dollars.

Along with its consortium partner, Alstom Environmental Control Systems, Shaw will retrofit Duke Power’s coal-fired generating units at its Belews Creek power plant in Stokes County, North Carolina.

The refit will involve installing flue gas desulfurization (FGD) units, also known as scrubbers, which will reduce up to 95% of the sulfur dioxide emitted from the plant, significantly improving the quality of air emissions from the facility. Shaw will perform the majority of the project’s engineering, procurement and construction. Alstom will design, engineer and procure the FGD equipment.

Engineering is already in progress and ground has been broken on the construction. The project is scheduled to be completed in 2008. The total value of the project, including equipment, is estimated to be approximately $500 million.

The Belews Creek award closely follows Duke’s earlier decision to give the scrubber retrofit job at its Marshall Steam Station, which is currently in process and expected to be completed in 2007, to Shaw and Alstom.
