  • 8/31/07 - Application for official certification (AFC) submitted with California Energy Commission


On August 31, 2007, Solar Partners we, LLC, Solar Partners II, LLC, Solar Partners IV, LLC and Solar Partners VIII, LLC (Solar Partners) presented a single Application for official certification (AFC) toward California Energy Commission to develop three solar power thermal energy plants and shared services close to the Ivanpah Dry Lake, in San Bernardino County, California on national land managed because of the Bureau of Land Management (BLM). The proposed project would be constructed in three phases: two 100-megawatt (MW) phases (generally Ivanpah 1 and Ivanpah 2) and a 200-MW phase (Ivanpah 3). The 3 flowers tend to be collectively named the Ivanpah Solar Electric Generating System (ISEGS) and could be positioned in:

  • Southern Ca's Mojave Desert, close to the Nevada edge, to your western of Ivanpah Dry Lake
  • San Bernardino County 4.5 miles southwest of Primm, Nevada, 3.1 miles west associated with California-Nevada edge
  • Township 17N, Range 14E, and Township 16N, number 14E

Venture Explanation

The proposed project includes three solar power focusing thermal power flowers, considering distributed energy tower and heliostat mirror technology, which heliostat (mirror) areas concentrate solar technology on energy tower receivers nearby the center of every heliostat range. Each 100-MW site would require about 850-acres (or 1.3 square kilometers) and will have three tower receivers and arrays; the 200-MW web site would require about 1, 600-acres (or 2.5 square kilometers) and could have 4 tower receivers and arrays. The full total area required for all three stages would like the administration building/operations and upkeep building and substation and become around 3, 400-acres (or 5.3 square miles). Given that the three flowers is developed in show, the recommended solar plant projects would share the most popular services stated earlier to add access roadways, as well as the reconductored transmission outlines for all three levels. Building regarding the entire task is anticipated to start in the first one-fourth of 2009, with construction becoming completed in the very last quarter of 2012.

Process Description

In each solar plant, one Rankine-cycle reheat steam turbine gets live vapor through the solar boilers and reheat vapor from one solar reheater located in the energy block at the top of its tower. The reheat tower would be found next to the turbine. Extra heliostats could be found beyond your power block border road, centering on the reheat tower. Last design layout places continue to be being developed. The solar power industry and energy generation equipment is begun every morning after sunrise and insolation build-up, and power down at night whenever insolation drops underneath the level expected to maintain the turbine on line.

Each plant also includes a partial-load normal gas-fired steam-boiler, which would be applied for thermal input on turbine through the early morning start-up period to aid the plant in approaching to operating heat more quickly. The boiler would also be run during transient cloudy problems, to be able to maintain the turbine online and able to resume production from solar power thermal input, following the clouds pass. After the clouds pass and solar power thermal feedback resumes, the turbine could be gone back to full solar production. Each plant utilizes an air-cooled condenser or "dry air conditioning, " to reduce water usage in web site's wilderness environment. Liquid consumption would therefore, be primarily to present liquid for cleansing heliostats. Additional equipment at each and every plant includes feed water heaters, a deaerator, an emergency diesel generator, and a diesel fire pump.

Electricity would be generated by each plant's Solar Receiver Boiler in addition to steam-turbine generator. The heliostat mirrors would-be organized around each solar power receiver boiler. Each mirror tracks the sun throughout the day and reflects the solar energy towards the receiver boiler. The heliostats would be 7.2-feet high by 10.5-feet broad (2.20-meters by 3.20-meters) yielding a reflecting surface of 75.6 sqft (7.04 square meters). They'd be organized in arcs around the solar power boiler towers asymmetrically.

Each solar power development phase would consist of:

  • an all natural gas-fired start-up boiler to give you heat for plant start-up and during short-term cloud cover;
  • an air-cooled condenser or "dry air conditioning, " to attenuate water consumption when you look at the website's wilderness environment;
  • one Rankine-cycle reheat steam-turbine that obtains live vapor from the solar power boilers and reheat vapor from a single solar reheater located in the power block near the top of a unique tower adjacent to the turbine; and
  • a natural liquid container with a 250, 000 gallon ability; 100, 000 gallons to be utilized the plant plus the remainder become set aside for fire liquid.
  • a small on-site wastewater plant located in the power block that treats wastewater from domestic waste channels particularly baths and commodes;
  • auxiliary equipment including feed-water heating units, a deaerator, an emergency diesel generator, and a diesel fire pump.


Ivanpah 1, 2 and 3 would be interconnected to your Southern Ca Edison (SCE) grid through updates to SCE's 115-kV line passing through website on a northeast-southwest right-of-way. Upgrades would integrate a new 220/115-kV breaker and-a-half substation between your Ivanpah 1 and 2 task internet sites. The current 115-kV transmission line through the El Dorado substation is replaced with a double-circuit 220-kV overhead line that could be interconnected on brand-new substation. Energy from Ivanpah 1, 2 and 3 is sent at 115-kV towards brand new substation.

Natural Gas

Natural gas supply for ISEGS would hook up to the Kern River gasoline Transmission business (KRGT) pipeline about 0.5 kilometers north associated with the Ivanpah 3 website.
