Solar One is located in the desert outside
Las Vegas near Boulder City, Nevada. It
is technically known as a Concentrated
Solar Power (CSP) generating station and
is a utility grade solar thermal facility.
The
64 megawatt commercial scale solar energy
plant is 350 acres covered in 182,000
mirrored troughs. These solar collectors
track the sun, concentrate light and convert
it into thermal energy at 750 degrees
Fahrenheit which creates steam for electrical
power generation.
More
than 18,240 vacuum tube steel and glass
receivers perform the task of turning
light into heat. The parabolic mirrors
focus the sun's energy on these vacuum-insulated
recievers and they absorb the solar radiation.
A heat transfer fluid circulates through
the recievers and transfers heat to a
water boiler that operates the 75 megawatt
turbine. Except for the solar collectors,
the plant is a standard natural gas generating
facility.
There
are nine similar projects in the Mojave
Desert in California. These older Solar
Electric Generating Stations (SEGS) in
the Mojave Desert are different from Nevada
Solar One.
Early
plants required a 25% natural gas-fired
backup to keep the temperature from changing
wildly as the supply of sunlight fluctuated.
Nevada Solar One is designed to be more
efficient in maintaining temperature and
requires only a 2% natural gas backup.
In essance Nevada Solar one is a natural
gas power plant with solar collectors
providing the primary heat source.
Nearly
750 people were involved in construction
of the facility and there is a permanent
full-time staff of 28.
