Invenergy unit files EWG notice for 350-MW Texas gas project

Ector County Energy Center LLC, an indirect subsidiary of Invenergy Investment Co. LLC that is developing a 350-MW gas plant in Texas, on June 20 filed with the Federal Energy Regulatory Commission a notice of self-certification as an exempt wholesale generator.

Ector is developing and will construct, own and operate an approximately 350-MW natural gas-fired project that will be located in Ector County, Texas. The Ector Project plans to begin generating electricity in the “future,” the company said, without specifying a timeline. Ector will sell electric energy and capacity produced from the Ector Project exclusively at wholesale.

The Ector Project will be comprised of natural gas turbines and associated facilities and equipment. The Ector Project will also include radial electric interconnection facilities that will interconnect to the transmission system owned by Oncor Electric Delivery Co. LLC.

Invenergy Thermal Development LLC is working at the U.S. Environmental Protection Agency’s Region 6 office on needed air permitting for the Ector County Energy Center project. The company filed a May 2013 application with EPA for a greenhouse gas prevention of significant deterioration permit on this project, located about 20 miles northwest of Odessa. The project features two simple-cycle, gas-fired combustion turbine generators. The application said that the turbines being considered were the General Electric 7FA.03 or 7FA.05 models, with nominal electric power output of 165 MW-193 MW apiece.

In a March 24 follow-up letter to EPA from permitting consultant Zephyr Environmental, Invenergy said it has analyzed the characteristics of electrical demand on the Electric Reliability Council of Texas (ERCOT) electrical grid in west Texas and specifically in the location of the proposed Ector County Energy Center. “Our analysis indicates a need of approximately 300 MWs of peaking capacity to respond to the relatively volatile market,” it added. “The 7FA.03 model gas turbines are very low cost units and fit this need quite nicely. Invenergy currently owns and holds two 7FA.03 gas turbines and has determined that the West Texas power market is the ideal area to install peaking turbines of this size.”

EPA issued a draft permit for this project in April, with no final permit issued yet.
