Power Plant Contracts for Siemens
Siemens Power Generation (PG) has received contracts to supply equpment to a United States power plant and provide preventive maintenance on a Russian combined-cycle plant. Siemens has been contracted by the municipality Roseville Electric to supply the power island equipment for the New Energy Park in Roseville, California, U.S.A. Siemens' will supply two 45 MW, SGT-800 gas turbines (formerly called GTX100), two duct-fired heat recovery steam generators, and a single 85 MW, SST-900 steam turbine (formerly called ST5). Engineering, project management and technical field assistance are also included, as are the total plant output and heat rate performance. Commercial operation is scheduled for spring 2007.
The plant at the Roseville Energy Park is planned to be a benchmark for highly flexible, yet efficient and environmentally friendly, power generation. The 166 MW plant, which will be used primarily to supply summer peak power, also can be operated off-peak at only 33 MW and still meet its emission guarantee of 2 ppm NOx / 4 ppm CO. The 2x1 design and optimized thermal cycle will enable a minimum efficiency of 44% at all load levels and up to 53 percent efficiency in base-load operation.
PG also has been awarded an order for a 15-year preventive maintenance agreement for a 140 MW combined-cycle plant in Riga, Latvia. The contract includes lead personnel from Siemens and special tools, instruments and parts for the length of the agreement. The contract includes five major overhauls and intermediate inspections for all three turbines (two gas turbines and one steam turbine). The SCC 800 2x1 plant (formerly called CC GTX100 2x1 is currently being built by Siemens PG as a turnkey project. The plant is owned by the Latvian national electricity company Latvenergo
