Brazos Electric Power Cooperative has applied to the Texas Commission on Environmental Quality (TCEQ) for issuance of proposed air quality permits that would authorize construction of the Hill County Generation Facility, a new natural gas-fired simple cycle combustion turbine power plant.
The TCEQ said in a Dec. 18 notice, posted to its website on Dec. 21, that the project site is at 3750 Farm-to-Market Road 66, Grandview, Hill County. This application was submitted to the TCEQ on Feb. 9, 2015. The commission’s executive director has determined that the emissions of air contaminants from the proposed facility which are subject to PSD review will not violate any state or federal air quality regulations and will not have any significant adverse impact on soils, vegetation, or visibility. All air contaminants have been evaluated, and “best available control technology” will be used for the control of these contaminants.
The major equipment consists of four natural gas-fired combustion turbines (CTs) powering electric generators (CTGs). Four CT/CTG models are being considered for selection: General Electric (NYSE:GE) 7FA.o3, GE 7FA.o4, GE 7FA.o5, and Siemens SGT6-5000F(5)ee. The total electric output of the four CTGs will be between 684 MW and 928 MW, depending on which model is chosen.
Although natural gas will be the normal fuel, the proposed permit allows limited CT operation on ultra-low sulfur diesel (ULSD) fuel oil as an emergency backup fuel. In addition to the major equipment, support equipment includes: two 1-MW emergency diesel engine generators, a 260-horsepower emergency diesel engine fire water pump, three small diesel fuel storage tanks for the emergency diesel engines, and two larger diesel fuel tanks for CT emergency use.
