Invenergy nears Texas permits for Ector County Energy Center

The Texas Commission on Environmental Quality is about to issue an Air Quality Permit and Prevention of Significant Deterioration (PSD) Air Quality Permit to Invenergy Thermal Development LLC that would authorize construction of the Ector County Energy Center.

The commission had issued a May 30 notice that it was about to approve these permits and on July 18 the draft permits entered the commission Executive Director’s agenda, which means the final permits are to be issued within three to 14 business days from that point.

The facility would be located near Goldsmith in Ector County. This application was submitted to the TCEQ in May 2013. This permitting authorizes two natural gas-fired combustion turbines (CTs) (identified as Unit 1 and Unit 2) to operate in simple cycle, and one emergency fire water pump engine. Each CT shaft drives an electric generator. The CTs may employ evaporative cooling for power enhancement.

This permitting authorizes construction and operation of one of the following two CT models: General Electric 7FA.03 or GE 7FA.05. Within sixty days after selection of the CT model, the permit holder must notify the Texas Commission on Environmental Quality of the selected CT model, submitted with an alteration request to revise this permit to delete language applicable to the non-selected CT model.

Ector County Energy Center LLC, an indirect subsidiary of Invenergy Investment Co. LLC that is developing this 350-MW gas plant, on June 20 filed with the Federal Energy Regulatory Commission a notice of self-certification as an exempt wholesale generator. The project will begin generating electricity in the “future,” the company said, without specifying a timeline. Ector will sell electric energy and capacity produced from the project exclusively at wholesale.

Invenergy Thermal Development is also working at the U.S. Environmental Protection Agency’s Region 6 office on needed air permitting for the Ector County project. The company filed a May 2013 application with EPA for a greenhouse gas prevention of significant deterioration permit on this project. The project features two simple-cycle, gas-fired combustion turbine generators. The application said that the turbines being considered were the GE 7FA.03 or 7FA.05 models, with nominal electric power output of 165 MW-193 MW apiece. EPA issued a draft permit for this project in April, with no final permit issued as of July 21.
