To NRG energy companies in the United States are generating Ivanpah solar power plants to visit is an amazing experience.
In any specific clear, if you drive to Las Vegas on the southwest of interstate 15, just like you in she across Nevada, California border, you will see on the right side of the road, with three towers and stretch for hundreds of thousands of acres of desert ground in mirror, mirror to absorb the sun's energy and reflect it to the tower.
On December 7, from PennWell company "power week" of a visitors in Ivanpah solar-thermal power stations experienced a technical tour.As the tour bus into Ivanpah solar-thermal power stations, and the viewer to see two of the three tower tower is running at full capacity.They visited the demonstration facilities, study the safety and environmental protection measures, also close through the 2 mirror field of the tower.
Ivanpah solar-thermal power station was completed in 2014, the plant boasts 175000 sets of heliostat, a total of 350000 surface reflector is characteristic.Reflector distributed in three different areas, the control system adjust the orientation of the mirror, to reflect sunlight collection hot tower, set the center of the tower is in each set hot area three 460 - foot - high tower.
Different from the photovoltaic panels on the roof will absorb sunlight, in turn, generate electricity, Ivanpah is using mirrors to reflect sunlight to heat tower, to heat the tower water to produce steam drive steam turbines.
According to NRG spokesman said, when the hot towers presentation luminescent state, Ivanpah solar power systems will generate electricity.After signed the necessary PPA agreement, the system will produce electricity to the national grid.
On December 7, visitors find Ivanpah solar power system normal operation, there were two tower was produced 822 MWH of electricity.Ivanpah power station consists of three towers: 1 tower is 126 mw, the no. 2 and no. 3 towers are 133 mw.In 2018, after four years of study in transition, Ivanpah facilities can produce 392 MWH of electricity per hour.
The spokesman said, if the condition is very good, sunny, no wind, for example, from 10 am to 2 PM these power stations can be full power to produce electricity.Ivanpah facilities located in the mojave desert, it's sunny is a big advantage.But the spokesman said there are many environmental factors affect the plant operation.
