Solar Electric Generating Systems ( SEGS ) are nine thermal solar thermal power plants in California , which are operated by NextEra Energy Resources , a subsidiary of NextEra Energy , and are partly owned by NextEra Energy .

backgrounds

The SEGS are thermal solar power plants that generate electricity through thermal solar technology and the use of parabolic reflector troughs. In combination with conventional natural gas , electricity is generated in this way in the Mojave Desert . The nine power plants have a combined output of around 354 MW and, as a network, form the world's largest solar operation of this type.

The thermal receivers, which absorb the sun's rays and transfer them to a carrier liquid (e.g. oil), were manufactured by the German company Schott Solar .

The individual power plants

The nine SEGS power plants were built by LUZ II Ltd. in San Bernardino County, California from 1985 to 1991 . (now a subsidiary of BrightSource Energy ) developed, built and operated.

From 1984 SEGS I with an output of 14 MW and the following year SEGS II at Daggett ▼ with 30 MW of electrical output for the utility Southern California Edison , a subsidiary of Edison International .

Five SEGS III - SEGS VII ▼ plants, each with an output of 30 MW, were built between 1986 and 1988.

The plants SEGS VIII and SEGS IX, which went into operation in December 1989 and November 1990 near Lockhart ▼, are currently (2008) the largest individual solar power plants in the world.

Power generation data

Theoretical performance says little about actual production.

The oldest plant (SEGS I, 1984) produced between approx. 20 GWh and approx. 17 GWh annually with a nominal output of 14 MW. That is about 1.4 GWh or 1.2 GWh per MW of power.

SEGS V (1988), with a nominal output of 30 MW, produced between approx. 70 GWh and approx. 60 GWh annually. That is about 2.3 GWh or 2.0 GWh per MW output.

The last plant (SEGS IX, 1990) produced between approx. 150 GWh and approx. 120 GWh annually with a nominal output of 80 MW. That is about 1.9 GWh or 1.5 GWh per MW output.

All in all, all plants (SEGS I to IX) with a nominal output of 354 MW produced between approx. 660 GWh and approx. 560 GWh with solar energy only. That is about 1.86 GWh or 1.58 GWh per MW output.
