NRG Receives Air Permit for Limestone 3 Coal Project in Texas

LCG, December 10, 2009--The Texas Commission on Environmental Quality (TECQ) approved permits for a new, coal-fired unit at the Limestone Electric Generating Station, which is owned and operated by NRG Texas, a wholly owned subsidiary of NRG Energy, Inc. (NRG).

NRG submitted a request to the TCEQ for an air permit to build the third unit at the Limestone facility in 2006, and a draft permit was issued in November 2007. Last month, the TECQ adopted the judges' proposed decision to issue permits and directed revisions be made prior to final approval of the order and the permit.

NRG is currently pursuing equity partners in the project, and an NRG spokesperson stated, "Receiving the permits is a very important step that will allow us to finalize agreements with our partners necessary to move forward on the project."

The Limestone Electric Generating Station is located near Jewett in Limestone County, approximately 120 miles northwest of Houston. The existing station includes two lignite/coal-fired steam units that provide over 1,700 MW of electric generating capacity.

The new unit will add approximately 744 MW of capacity and is estimated to cost over $1 billion. The construction duration is expected to be approximately four years.
