Siemens Set Up For Power Upgrades

Posted on March 10, 2011

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 Corp. (OPC), Georgia, U.S.A., power plants with the Siemens Power Plant Automation T3000 (SPPA-T3000) system. The new controls are designed to improve plant operation, maintainability, reliability and efficiency at each location, Siemens said.

The Siemens scope of supply consists of supplying SPPA-T3000 control upgrades for OPC’s Chattahoochee combined cycle energy facility, in addition to its Smarr, Hawk Road, Sewell Creek and Talbot County simple cycle energy facilities located in Georgia. The first upgrade will take place at the Chattahoochee facility during the plant’s November 2011 outage. The remaining projects will be implemented between now 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.

Also, Siemens will install and test its SPPA-E3000 electrical system at four new power houses of American Municipal Power’s (AMP) Ohio River Project, as part of a contract with Voith Hydro Inc., a subcontractor for AMP. The Ohio River Project consists of four power houses with 11 bulb-type turbines. The hydroelectric plants are located at the existing locks at four sites in Kentucky and West Virginia, U.S.A. The Ohio River projects have an expected capacity of 313 MW, Siemens said.
