Siemens Energy's Instrumentation, Controls, & Electrical (IC&E) Business Unit has signed two new contracts for its plant-wide distributed control systems. Siemens will upgrade the existing control systems of five Oglethorpe Power Corporation (OPC) power plants with the Siemens Power Plant Automation T3000 (SPPA-T3000) system. The new controls are expected to improve plant operation, maintainability, reliability, and efficiency at each location. Additionally, Voith Hydro, Inc., subcontractor for American Municipal Power (AMP), has contracted Siemens to install and test its SPPA-E3000 electrical system at four new power houses of AMP's Ohio River project.
The Siemens scope of supply for the OPC order consists of providing SPPA-T3000 control upgrades for the Chattahoochee combined cycle energy facility, in addition to its Smarr, Hawk Road, Sewell Creek, and Talbot County simple cycle energy facilities located in the Georgia. The first of the five energy facility controls upgrades will take place at the Chattahoochee Energy Facility during the plant's November 2011 outage. The remaining projects are scheduled to be implemented between March 2011 and March 2014. Siemens will supply its SPPA-T3000 control system for the 17 gas turbines, one steam turbine, two heat recovery steam generators, and the balance-of-plant controls that are spread across the various sites. The newly installed control systems will provide an easy-to-use single control platform for each energy facility.
The Ohio River project consists of four new power houses with a total of 11 bulb-type turbines. The four run-of-the-river hydroelectric plants are located at the existing locks at the sites of Willow Island near Waverly, West Virginia; Cannelton in Hancock County, Kentucky; Smithland in Livingston County, Kentucky; and Mehldahl in Bracken County, Kentucky. Combined, these projects have an expected capacity of 313 MW. All four hydroelectric plants provide renewable energy for AMP customers in the Ohio River area. Siemens' scope of supply is to provide the integrated SPPA-E3000 electrical system, which will provide the electrical controls, as well as synchronization, coordination, and protection for all of the 11 bulb turbines. The subcontract was signed with Voith Hydro, Inc., with the end owner being AMP and the owner's engineering company MWH.
"The OPC order is further evidence that our SPPA-T3000 control system, with its easy handling, high performance, and lowlife cycle cost, is increasingly becoming the control system of choice for power plants throughout the United States," said Joerg Holzapfel, general manager of Siemens Energy's U.S. Instrumentation & Electrical Business Unit. "Additionally, our ability to build, integrate, test, and commission automation projects of the magnitude of the Ohio River project all under the same roof is a unique capability that is of great value to our customer base."
