The Enterprise Waha Plant GE Turbine, along with El Paso's Solar turbines, are down for maintenance through Thursday. Without compression available at Waha, El Paso said it will be dependent on pressures at individual interconnects in the area. IMLWAHA was able to flow up to 100 MMcf/d on Monday but is now shut in through Thursday, El Paso said, while eight other interconnects can receive/deliver their normal volumes at Waha subject to the pressure limitations.
