Siemens Energy has received an order for the supply of an SPPA-T3000 instrumentation & controls (I&C) system and two steam turbine-generators for the Ivanpah solar thermal power plant located in the Mojave Desert.
The purchaser is BrightSource Energy Inc., a developer of utility-scale solar thermal power plants. Siemens will supply the SPPA-T3000 for all three units of the Ivanpah project with a combined installed capacity of approximately 400 megawatts (MW). This is the first deployment of the I&C system in a solar tower power plant of this size. For Ivanpah Units 2 and 3 the company will also supply two steam turbines and two generators. The start of commercial operation of the Ivanpah Units 2 and 3 is scheduled for 2013. The plant's capacity will be sufficient to supply approximately 140,000 households with power and is expected to reduce annual CO2 emissions by more than 400,000 tons.
Siemens will equip the first 126-MW unit and the 133-MW Units 2 and 3 with its SPPA-T3000 I&C system. Siemens will also implement the linkup to an asset management system. The customer will receive the I&C controls from a single source with smooth transitions between the turbine I&C and the I&C for the ancillary systems, reducing the customer's requirements in terms of personnel training and operating and maintenance costs.
"BrightSource Energy opted for our I&Csystem because it covers both the steam turbine and the balance of plant. We're pleased that we can extend our long-term success and global track record to now serve the solar thermal market with our SPPA-T3000 I&C," said Karlheinz Springer, CEO Instrumentation, Controls & Electrical at Siemens Energy.
In October 2008, Siemens received an order for the supply of a steam turbine and generator for Ivanpah Unit 1. In addition to Unit 1, Siemens will now also supply two steam turbines each rated at 133 MW and two generators for Ivanpah Units 2 and 3. The SST-900 turbine is ideally suited for deployment in solar thermal power plants. This turbine is known for its fast startup and shutdown capability, and the fact that it can very flexibly track the respective operating conditions of solar thermal power plants. Steam reheat enhances the efficiency of the turbine and thus of the entire power plant. The two turbines for Ivanpah 2 and 3 will be delivered in the summer of 2012.
