A scrubber retrofit project at the coal-fired Flint Creek power plant is going well and currently tracking under the projected budget, said an outside monitor report from Garver LLC filed on Oct. 19 at the Arkansas Public Service Commission by plant co-owner Southwestern Electric Power.
The flue gas desulfurization (FGD) project includes the installation of an Alstom Novel Integrated Desulphurization (NID) system to comply with the Mercury and Air Toxics Standards (MATS) and in anticipation of Best Available Retrofit Technology (BART) Rule. The NID system and associated equipment are to be constructed adjacent to and on the south side of Flint Creek Unit 1, the only unit at the plant. The project also includes an Activated Carbon Injection (ACI) system between the NID and the Unit 1 burners.
Southwestern, a unit of American Electric Power (NYSE: AEP), has secured a one-year extension to the MATS deadline, to April 2016, and has established design, procurement, and construction schedules that will bring the upgraded plant fully on line by May 29, 2016.
Garver conducted a site visit in conjunction with the monthly construction progress meeting on Aug. 9, 2015. Photographs of the project are included in the report. Garver has reviewed the financial data, monthly and weekly reports, project scope change requests, and other documentation for the project.
The project is progressing well and is scheduled to be complete by the deadline, said the report. The structural/mechanical package is 60% complete and the electrical package is 28% as of Aug. 30, 2015.
The overall budget for the FGD project is $389.9 million through Phase 3. This budget includes design, construction, and procurement. The project has spent 67% of the budget through August 2015. The forecasts indicate that the project will be completed under budget by $18.4 million. The contingency for the project has been reduced by $15 million during 2015.
The plant is co-owned by the Southwestern Electric Power and Arkansas Electric Power Cooperative. Flint Creek is a baseload, pulverized coal-fired unit with a net generating capacity of 528 MW. The plant was put into commercial operation in 1978.
