Halyard Energy Ventures LLC announced Jan. 12 that the Texas Commission on Environmental Quality (TCEQ) had issued an air quality permit authorizing the construction and operation of the Halyard Henderson Energy Center (HHEC) in Henderson County. It said the HHEC will be a natural gas-fired, simple-cycle facility. It has received all permits required to begin construction, including its air quality permit and water supply permit.

The project is located within the Electric Reliability Council of Texas (ERCOT). TCEQ records show the plant site is located on County Road 4402, approximately 0.30 miles west of the intersection of County Road 4402 and Texas Farm to Market 2588, near Larue in Henderson County.

“With five natural-gas developments underway and two of them fully permitted, we are taking a lead in delivering added capacity to meet energy demand within ERCOT,” said Karl Dahlstrom, partner at Halyard. “Our projects deliver flexible, quick-start, efficient peaking capacity to complement renewable power in the market.”

Headquartered in Houston, Texas, Halyard Energy Ventures was formed to manage the greenfield development, construction and operation of a portfolio of five gas-fired simple-cycle power plant projects within ERCOT. The principals of Halyard have a long track record of developing commercial scale power plants from inception to operation.
