The U.S. Environmental Protection Agency’s Region 6 office on May 12 issued a final air permit to Indeck Wharton LLC for a 650-MW, gas-fired peaking project in Texas.
In June 2013, the company submitted to EPA Region 6 a Prevention of Significant Deterioration (PSD) permit application for Greenhouse Gas (GHG) emissions from its Indeck Wharton Energy Center project. In connection with the same project, Indeck in the same month submitted a PSD permit application for non-GHG pollutants to the Texas Commission on Environmental Quality (TCEQ).
Indeck Wharton, an affiliate of Indeck Energy Services, proposes to construct a 650-MW peaking power project located near Danevang in Wharton County. Indeck plans to construct three identical natural gas-fired simple cycle turbines, utilizing either the General Electric Model 7FA.05 or Siemens SGT6-5000F(5), and associated equipment, an emergency diesel generator, a gas pipeline heater, a firewater pump engine, and fourteen circuit breakers.
The primary objective of the proposed project is to provide peaking capability, which will be used during periods of increased demand for electricity. Due to the fluctuations in power requirements, the three new natural gas-fired simple-cycle turbines (215-225 MW each) are proposed to provide a fast ramp up for electricity generation.
The GE 7FA.05 has a base-load electric power output of about 213 MW (net nominal), and the Siemens SGT6-5000F(5) has a base-load electric power output of approximately 225 MW (net nominal). Each CTG will burn pipeline natural gas to rotate an electrical generator to produce electricity.

In June 2010, EPA finalized national GHG regulations, which specify that beginning in January 2011, projects that increase GHG emissions substantially will require an air permit. EPA said it believes states are best equipped to run GHG permitting programs. Texas is working to replace a federal implementation plan with its own state program, which will eliminate the need for businesses to seek air permits from EPA. EPA has now finalized 37 GHG permits in Texas, proposed an additional 10 permits, and currently has over 28 GHG permit applications under review in Texas.
