Oahe Dam

Owner: U.S. Army Corps of Engineers, Pierre, SD
Client: CE Power Solutions

Project Summary: RMS Energy was mobilized by CE Power Solutions to refurbish the Isolated Phase Bus at the Oahe Dam, a hydroelectric facility that generates electricity for much of the north central portion of the United States. The project involved installation of new gaskets on all Isolated Phase Bus split covers, and resealing of the metal plate on the concrete pedestal where the IPB passes through the tailrace deck. Drip edges were also installed on every joint of the vertical IPB risers to prevent water seepage or collection.

About the Client: CE Power Solutions provides electrical systems solutions for 480V through 765kV electrical systems. They serve electric utility power plants, alternative energy facilities, transmission and distribution substations, industrial facilities, institutional facilities and facilities with critical power applications.

Details:

  • Installed new gaskets on all Isolated Phase Bus split covers, at all joints, and on all doors

  • Resealed the metal plate on the concrete pedestal where the Isolated phase bus passes through the tail race deck

  • Inspected the Porcelain through Bushings, Drain Ports, and Bus Duct internals and externals

  • Replaced the Rubberized boots connecting the Isolated Phase Bus to the transformers

  • Installed drip edges above every joint on the vertical IPB risers to ensure that water did not collect on the joint, which would risk seepage

Oak Creek Power Plant

Owner: WE Energies

Project Summary: Onsite inspection.

About the Client: Oak Creek Power Plant, also known as South Oak Creek, is a base load, coal- and natural gas-fired, electrical power station located on Lake Michigan in Oak Creek, Wisconsin.

Owner: Entergy

 

Project Summary: RMS Energy was hired to perform a variety of inspections and maintenance work at this facility. See details below.

About the Client: Located near Monroe, Louisiana, the Perryville Plant is a natural gas-fired plant which includes a 562 MW combined-cycle unit and a 156 MW simple-cycle unit.

Details:

  • Inspect all reachable components of the Isophase bus for deficiency

  • Remove reachable insulators if necessary and inspect for amount of dirt/dust build up 

  • Inspect for cracks, chips, tracking, arcing, corona, base separation b. Inspect inside enclosure- readily accessible areas from bolted covers or access covers 

  • Inspect for flaking paint, water intrusion, dust and dirt buildup and foreign material

  • Inspect conductor- readily accessible areas from bolted or access covers 

  • Surfaces should be silver plated 

Petersburg Generating Station

Owner: Indianapolis Power and Light

 

Project Summary: RMS Energy was contracted to conduct a compressive analysis and subsequent cleaning/repair of the Isolated Phase Bus (IPB) system of the Petersburg Generating Station. RMS Energy provided an onsite field technician to assist the client in determining the scope and scale of the work required, as well as obtaining all necessary field measurements and quantities, thus allowing the field tech to make recommendations on all required new parts. After the initial analysis, the project required the cleaning and installation of the new components, allowing for a significant upgrade to the system.


About the Client: The Petersburg Generation Station in Petersburg, Indiana, is a coal-fired power generation station owned and operated by Indianapolis Power and Light.  The 1.87GW facility services the power needs of greater Southwest Indiana. CE Power Solutions provides electrical systems solutions for 480V through 765kV electrical systems. They serve electric utility power plants, alternative energy facilities, transmission and distribution substations, industrial facilities, institutional facilities and facilities with critical power applications.

 

Details:

  • Provided an onsite Field Service Technician to perform a complete inspection and recommendation for new parts required and develop a scope of work, field measurements and quantities identified

  • Cryogenically clean IPB, hand wiped insulators

  • Provided and installed new: electrical connection hardware (SS bolts, nuts, flat washers, conicals), Rubber boot assemblies, 800MCM flexible connectors
