Eliminating the Water
On Sept. 29, 2011, LADWP broke ground on the $782 million
repowering project. The major equipment started arriving
in mid-March 2012, and by April 2, three 190-ton turbines,
182-ton generators, and 100-ton dry cooling towers had been
2. Water, water, everywhere, but not a drop to cool.
The first two units are shown here during construction, with the generator
and the LMS100 to the right of the foreground and the intercooler
in the left background. The units do not use any ocean cooling water,
unlike the units they are replacing. California requires generators to
severely reduce the amount of ocean cooling water used in future
plants. Courtesy: LADWP
delivered to the site, with the other three units arriving last
summer. Testing and tuning began last November and continued
through April 2013, so the peakers will be ready for the
2013 summer season.
" We are targeted for substantial completion in June of
2013, and everything is looking on schedule for that to happen, "
says Dennis.
In the meantime, the utility is progressing on its second repowering
project: replacing the three units at the Scattergood
Generating Station near Los Angeles International Airport. As
of this writing, LADWP is finalizing contracts before beginning
work to replace Unit 3, which is scheduled for completion at
the end of 2015. The Scattergood project will include a mix
of simple cycle units and combined cycle units with similar
options for clutches as at Haynes. Either way, it will include
dry cooling towers.
Next on the list are the other two units at Scattergood,
then two more units at Haynes, one unit at the Harbor Generating
station, and then finally replacing the combined cycle
units installed at Haynes by 2029. At that point, the LADWP
will no longer be using any ocean water for cooling at any of
its plants.
" Not only can we meet our energy demands, " says Dennis,
" but incrementally step down the use of ocean water, increase
our use of renewable energy from 20% to 33% by 2020, increase
our energy efficiency by 10% by 2020, and reduce our
CO2
and NOx
emissions. " ■
