NRG and Optim Energy hold an equal share in the unit. Constructed by San Antonio-based Zachry, the plant’s required principal equipment was supplied directly by NRG. NRG would operate the plant and Optim Energy is the energy manager for Cedar Bayou unit 4.
The plant augments the Texas grid by adding around 550MW of power, which is sufficient to power approximately 440,000 homes. The unit has the flexibility to start in as little as 30 minutes to respond to rapidly changing load conditions.
Cedar Bayou unit 4 uses the Best Available Control Technology prescribed by the Texas Commission on Environmental Quality. The heat recovery steam generator has a catalytic reduction system to further reduce NOx emissions and the combustion turbines are fitted with ultra-low nitrogen oxides (NOx) burners.
T. Smitherman, Texas Public Utility Commission Chairman Barry, said: “We are very pleased that NRG and Optim Energy have made this investment in clean and efficient electricity generation in Texas. This is an important addition to our grid to address our increasing demand for economic and reliable power.”
