Ozark Powerhouse Rehabilitation Program

The Ozark-Jeta Taylor Lock and Dam and Ozark Powerhouse are located 1-mile southeast of Ozark, Arkansas on the Arkansas River. The electricity produced at the Ozark Powerhouse is sold to customers in Arkansas, Kansas, Louisiana, Missouri, Oklahoma, and Texas. The Ozark Powerhouse has been unique since it was constructed because it was the first slant-shaft turbine powerhouse built by the Army Corps of Engineers. Webbers Falls, located upstream from Ozark on the Arkansas River, and Truman in Missouri, are the only other large, slant-axis installations in the Corps.

Due to flaws in the original design of these units, all have been subject to frequent failures. Ozark will be the first slant-shaft turbine powerhouse to go through a major rehabilitation.

The Rehabilitation Project is a $77 million initiative which will improve the design and restore operation to the 5-turbine unit/100 megawatt hydropower facility. The Project started in 2005 and was scheduled for completion in 2012. However, when disassembly of the units began in 2008, several repair issues surfaced, putting significant risk on successful completion of the project.
The Corps hired MOCA in 2009 to help manage the recovery of the project. MOCA has been providing project control and claims management services to improve the performance of financial and schedule goals. The MOCA team is helping to bring the project back into alignment with financial and scheduling objectives.
