Ivanpah 1, 2 and 3: Thermal Tower Solar Plant by BrightSource Energy

BrightSource Energy is seeking the approval of a 400 megawatt a three-part solar-thermal powerplant to be built in the Mojave Desert, collectively called the Ivanpah Solar Electric Generating System (ISEGS) 1   2   3  

The new solar energy facility will actually consist of 3 concentrating solar thermal power plants that are each based on Distributed Power Tower (DPT) and heliostat mirror technology. Construction will be carried out in a phased approach with two 100 megawatt phases (known as Ivanpah 1 and Ivanpah 2) and a 200 MW phase (Ivanpah 3). Each of the 100MW sites would take up around 850 acres and would consist of 3 tower receivers and arrays; the 200 MW site would take up around 1,600 acres and would consist of 4 tower receivers and arrays.

Construction of the project is expected to begin in the first quarter of 2009, and to be completed in the last quarter of 2012. The three plants would be built on federal land managed by the Bureau of Land Management (BLM).

The project calls for power line upgrades to connect the new facility to grid infrastructure owned by Southern California Edison (SCE), connection to the existing Kern River Gas Transmission Company (KRGT) pipeline close to the Ivanpah 3 site, and extraction of ground water to supply the turbines and to wash the heliostated mirrors.
