Ivanpah Solar Electric Generating System (ISEGS)

Ivanpah Solar Electric Generating System – BrightSource’s LPT solar thermal system is currently being deployed at the Ivanpah Solar Electric Generating System (ISEGS) in California’s Mojave Desert. Ivanpah, which started construction in October 2010, is the first project that will deliver power to serve the company’s signed contracts with PG&E and Southern California Edison.

The project – which counts NRG Solar, Google and BrightSource as equity investors – is currently the largest solar plant under construction in the world.A 392 megawatt gross solar complex using mirrors to focus the power of the sun on solar receivers atop power towers.

  • The electricity generated by all three plants is enough to serve more than 140,000 homes in California during the peak hours of the day.
  • The complex will reduce carbon dioxide (CO2) emissions by more than 400,000 tons per year.
  • Located in Ivanpah, approximately 50 miles northwest of Needles, California (about five miles from the California-Nevada border) on federal land managed by the Bureau of Land Management.
  • The complex is comprised of three separate plants to be built in phases between 2010 and 2013, and will use BrightSource Energy’s LPT solar thermal technology.

    Glad to see that part of Nevada leading the way in solar energy. With over 250 days of sunshine per year, it’s one of the best places in the world, never mind the US, for solar power to be implemented, so it’s no surprise to see that giant solar farm opened here. As a solar contractor myself, we’re also installing more and more PV systems on residential houses too, so it’s clear the technology is finally catching on in the mainstream.

    Although Ivanpah project might be viewed as my competition, I’m personally very encouraged and impressed by it. The more we embrace alternative energy sources like solar, the better it is for everyone.

    Solar energy that can power over 140k homes is amazing. I can’t imagine where we will be in 10 or 20 years with the advancement of solar energy and it’s exponential growth. People are looking for ways to save money and lower their footprint and projects like this push solar energy into the public eye. Great information and the future for solar energy excites me.

    What a great investment and brilliant as well. To use the mirror as reflectors and generate 392 megawatt power is incredible. To power 140,000 homes is a huge benefit that will help our planet. We’ll have to wait and see how long it takes for the rest of the world to catch on to this massive power plant and begin generating enough power to service a percentage of the population. This was a very informative post!
