The Los Angeles Department of Water and Power (LADWP) has begun its $782m repowering of the Haynes natural gas-fired power plant in Long Beach, California, the first in a series of projects to end the use of seawater for cooling in coastal plants.
Two natural gas fired units ” of 292 MW and of 238 MW ” will be replaced with six 100 MW fast-start natural gas combustion turbines with a dry cooling system.
LADWP aims to bring the new units online by the end of 2013.
Haynes is the first of a series of repowering projects with an estaimated total cost of $2.2bn to eliminate the use of seawater in once-through cooling at three coastal plants, said LADWP.
LADWP said its repowering target dates are: Haynes 5 and 6 in 2013, Scattergood 3 in 2015, Scattergood 1 and 2 in 2024, Haynes 1 and 2 in 2029, Harbor 5 in 2029 and Haynes 8 in 2029.
Haynes is a 1524 MW natural gas and oil fired power plant with seven units. LADWP repowered Units 3 and 4 in 2005 with a combined-cycle plant (Units 8-10).
