[18][19] The Ivanpah system consists of three solar thermal power plants on 3,500 acres (1,400 ha) of public land near the California–Nevada border in the Southwestern United States.
[23] The plants use BrightSource Energy's "Luz Power Tower 550" (LPT 550) technology[24] which heats the steam to 550 °C directly in the receivers.
[27] On October 27, 2010, Governor of California, Arnold Schwarzenegger, Interior Secretary Ken Salazar, and other dignitaries gathered in the Mojave Desert to break the ground for the construction.
[28] In November 2011, Google announced that it would no longer invest in the facility due to the rapid decline of the price of photovoltaic systems.
[33] The facility developed contracts to sell about two-thirds of the power it generated to the Pacific Gas and Electric Company (PG&E), and the rest to Southern California Edison (SCE).
The Wall Street Journal reported, "Instead of ramping up the plant each day before sunrise by burning one hour's worth of natural gas to generate steam, Ivanpah needs more than four times that much.
The California Energy Resources Conservation and Development Commission approved for each a stack "130 feet (40 m) high and 60 inches (1.5 m) in diameter" and consumption of 242,500 cu ft/h (6,870 m3/h) of fuel.
[44] According to Synapse Energy Economics, the estimated construction cost for the facility of $5,561.00 per kW fell between that of coal and nuclear power plants.
[50] In June 2015, The Wall Street Journal reported, "15 months after starting up, the plant is producing just 40% of [its expected more than a million megawatt-hours of electricity each year], according to data from the U.S. Energy Department.
CleanTechnica reported with respect to units 1 and 3 that "in 2015, PG&E customers received about 97% of Ivanpah's contracted electrons, which is a massive improvement over its first year".
[6] The local irradiance near the area is about 7.4 kWh/m2/day[53][54] (annual average) for a total solar energy flow in the visible spectrum of 2.717 MWh/m2 yearly.
If the mirrors could always be perpendicular to Sun's ray, based on irradiance, the intercepted solar energy flow is 2.717 MWh/m2/year × 2,437,144 m2 = 6,621,720 MWh yearly.
It was designed to minimize impacts on the natural environment compared to some photovoltaic solar facilities because the use of heliostats does not require as much grading of the land.
[63][64] In 2012, the National Parks Conservation Association (NPCA) issued a report on the project, citing water concerns, damage to visual resources, and impacts on important desert species.
... Because they are high above the ground, these glowing receiver units will be a visible distraction to persons at many of the KOPs [Key Observation Points], including travelers utilizing I-15.
The panoramic expanse of mirror arrays would present strong textural contrast with the intact, natural character of the desert floor [and] would rise to a height of roughly 459 feet [140 m]; an additional 10 to 15 feet [3.0 to 4.6 metres] above that height would consist of lighting to meet Federal Aviation Administration (FAA) requirements.
"[21] The Ivanpah Solar power project was built on 6 square miles (16 km2) of public land in the south central Mojave Desert.
[67] Construction resumed when the United States Fish and Wildlife Service (USFWS) found the project was not likely to jeopardize the endangered desert tortoise.
[73] In April 2014, the USFWS reported that 141 dead birds, including peregrine falcon, barn owl and yellow-rumped warbler had been collected at Ivanpah in October 2013.
[79] In April 2015 The Wall Street Journal reported that "biologists working for the state estimated that 3,500 birds died at Ivanpah in the span of a year, many of them burned alive while flying through a part of the solar installment where air temperatures can reach 1,000 degrees Fahrenheit [540 °C]".
[80] In late 2015, Brightsource released the results of the first full year monitoring bird and bat deaths at the Ivanpah solar plant.
In September 2014, for example, Renewable Energy World suggested "With its claim of 28,000 dead birds from Ivanpah, the Associated Press syndicated a story on every front page in America, spreading alarm about concentrated solar power (CSP) plants, which was not grounded in facts, but on one opponent's speculation.
"[83][84] In September 2016, federal biologists said about 6,000 birds die from collisions or immolation annually while chasing flying insects around the facility's towers.
The commissioning of a new thermal plants requires up to four years to achieve 100% operating level, from the first grid connection to full production.
