Project is an addition to the approved Blythe Energy Project and will be built within the existing property boundaries of the existing project. The site is located near Interstate 10 and the Blythe airport, about 5 miles west of the City of Blythe. The site is defined as located in the eastern 1/2 of the NW 1/4, Section 33, Township 6 South, Range 22 East.


Estimated cost of $250 million.


The AFC is submitted under the six-month licensing process pursuant to Title 20 of the California Code of Regulations (CCR), Division 2, Chapter 5, Article 7, which contains provisions for expedited applications under Public Resources Code Section 25550.


Construction is planned to begin in late 2002, with full operation expected in April 2004.

Commercial Operation:

BEP II will generate approximately 4.5 million Mw-hours per year.


BEP II will be electrically interconnected to the Buck Blvd. Substation, located at the northeastern corner of the approved BEP site. The Buck Blvd. substation will connect to the Western owned Blythe substation and the Midway substation owned by Imperial Irrigation District (IID). The Blythe Substation interconnects five existing 161 kV regional transmission lines. Three of the transmission lines are owned by Western, one by IID, and the other by Southern California Edison (SCE).


The project is a nominally rated 520 MW combined-cycle power plant.


BEP II consists of two Siemens Westinghouse V84.3a 170 MW combustion turbine generators (CTGs), one (1) 180 MW steam turbine generator and supporting equipment. BEP II requires no offsite linear facilities in addition to the approved BEP offsite linear facilities (e.g., transmission line and natural gas pipelines).

Transmission Line:

BEP II will not require the construction of new transmission lines.


Natural gas will be supplied to the BEP II Plant by the natural gas pipeline being constructed as part of the approved BEP.

Water Supply:

Water will be supplied by one (1) additional groundwater well having the capacity to pump up to 3,000 gallons per minute (GPM).

Air Quality & Emission Controls:

Emissions will be controlled with the use of state-of-the-art Selective Catalytic Reduction technology and compliance with all applicable laws, ordinances, regulations and standards (LORS).


Wastewater treatment systems being considered as part of the approved BEP will be duplicated in BEP II. After maximum recycling of water through the plant, wastewater will be discharged to a new evaporation pond resulting in a zero liquid discharge system.
