Flint Creek air retrofit project tracking on time and under budget

Consulting firm Garver LLC, the independent monitor for an air emissions control project at the coal-fired Flint Creek plant, on May 5 filed a quarterly report with the Arkansas Public Service Commission on progress so far.

Flint Creek is a base load, pulverized coal-fired unit with a net generating capacity of 528 MW. The plant was put into commercial operation in 1978. The unit is co-owned equally by Southwestern Electric Power and Arkansas Electric Cooperative.

The 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 the 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 project also includes an Activated Carbon Injection (ACI) system between the NID and the Unit 1 burners. 

Garver noted that Southwestern Electric Power has secured a one-year extension to the federal Mercury and Air Toxics Standards (MATS) deadline and has established design, procurement, and construction schedules that will bring the upgraded plant fully on line by May 29, 2016.

This report is the fourth quarterly report issued by Garver and covers the first quarter of calendar year 2015. American Electric Power Service Corp., another subsidiary of Southwestern Electric Power parent American Electric Power (NYSE: AEP), selected Garver as the Independent Monitor (IM) for this project. Garver’s IM services are limited to the procurement and construction portions of this fast-tracked program.

The Capital Improvement (CI) budget for the project through Phase 3 is $389.96 million. At this time, the total estimated cost at completion of the project is $383.56 million. Project financials are strong and are pointing towards a significant savings of approximately $6.3 million, Garver said. The expenditures for the first quarter of 2015 are above anticipated expenditures in both the Construction Contracts and Materials categories. For the Construction Contracts category, Marietta Silo has completed the lime silo ahead of schedule. As for Materials, several large deliveries of materials have arrived on site before their scheduled delivery date.
