The Massachusetts Department of Public Utilities and Energy Facilities Siting Board have scheduled July 7-8 and July 11-12 hearings on companion December 2015 applications from NRG Canal 3 Development LLC for approval of a 350-MW expansion of an existing power plant.
In a June 2 update, NRG Canal 3 noted that its turbine manufacturer, General Electric, recently provided a guarantee that carbon monoxide (CO) emissions will not exceed 3.5 ppm when the facility is operating on natural gas, which, in turn, translates to a Facility Emission Rate when firing natural gas of 0.076 lbs/MW-hr for CO. With this revised emission rate for CO, the proposed facility now complies with Technology Performance Standards, which means a lesser level of technical data that needs to be supplied.
In December 2015, NRG Canal 3, a unit of NRG Energy (NYSE: NRG), submitted petitions to construct a new power plant in the Town of Sandwich, capable of generating 350 MW. This is to be located at the existing 52-acre Canal Generating Station site on Freezer Road. The new facility is expected to operate during times of peak energy demand, for up to 4,380 hours per year and would run primarily on natural gas, with up to 1,440 hours per year on ultra-low sulfur distillate (ULSD), as the back-up fuel.
The new facility will include one state-of-the-art simple-cycle combustion turbine with a net nominal electrical output of approximately 350 MW. The proposed facility will be equipped with state-of-the-art emissions control technologies, a near-zero liquid discharge system to reduce water demand, and noise attenuation, including housing the new turbine in an acoustically treated enclosure.
