PGE -biggest investment into solar, ever

California Utility Signs $3 Billion Solar Power Deal
By Matt Nauman
The San Jose Mercury News
Tuesday 01 April 2008
Utility project would put five power plants in the Mojave Desert.


Pacific Gas & Electric today will announce a deal to buy as much
as 900
megawatts of electricity. It will be enough to power 540,000 California
homes each year, and involve the construction of five solar power plants
during the next decade. The company to build the solar-thermal power
plants
in the Mojave Desert is BrightSource Energy.


"From what I know, this is the biggest commitment ever in the
history
of solar," said John Woolard, BrightSource Energy's chief executive
officer
and president. "It's a fairly significant undertaking on both sides."


Building all five plants in the Mojave will cost $2 billion to $3
billion, Woolard said. The project, which faces regulatory and financing
hurdles, could mean 2,000 construction jobs, and employ about 1,000
workers
to operate the plants.


BrightSource's founder and chairman is Arnold Goldman, whose
now-defunct Luz International built nine solar plants in the Mojave
Desert
between 1984 and 1990. They're still operating.


BrightSource uses what it calls distributed power towers, or DPTs,
in
which sunlight from thousands of movable mirrors are concentrated to
heat
water to more than 1,000 degrees in a boiler to make steam. That steam
feeds a turbine that makes electricity.


BrightSource will begin the first demonstration of its technology
at a
small-scale plant in Israel in April. It anticipates the first of its
five
California plants for PG&E, a 100-megawatt facility, to be up and
running
"as early as 2011," Woolard said. That plant, and a larger 200-megawatt
plant scheduled to begin operation in 2012-13, will be built on the
Ivanpah
dry-lake bed in San Bernardino County.


Three other BrightSource 200-megawatt solar plants also are
planned, to
be built from 2014 to 2016 at the Broadwell dry lake, about 100 miles
southwest of Ivanpah.
