Unplanned maintenance over the weekend on Wenden Station’s Solar turbine necessitated a Havasu Crossover reduction from 630,000 MMcf/d to 590,000 MMcf/d, El Paso said, but the work was completed in time to allow the restoration of 630,000 MMcf/d in Crossover capacity effective with Sunday’s Cycle 2 nominations. El Paso also reported that Line 1300 pigging between the Roswell and Caprock stations on Tuesday through Thursday this week will require a flow rate of 250 MMcf/d, or a 370 MMcf/d reduction from full San Juan Crossover capacity of 620 MMcf/d. The pig runs are expected to take eight hours each day, so El Paso intends to reinstate approximately 230 MMcf/d of Crossover capacity on Cycle 3 each day. “We cannot prorate the volume for the day to include Cycles 1 and 2, because there would be too much gas flowing for the first eight hours of the day,” the pipeline said.

Florida Gas Transmission lifted an Overage Alert Day notice Saturday.

Saying maintenance on Belen (NM) Station’s #1 turbine had been completed ahead of schedule, El Paso increased capacity of the San Juan Crossover to 650 MMcf/d Friday.

El Paso reported that in conjunction with the White Rock Station controls replacement project, the White Rock 1 turbine compressor was disassembled “and it has been determined that repairs can not be completed within the original time frame.” Following completion of the station’s controls replacement, due April 27, White Rock 1 will remain down through May 3, reducing El Paso’s San Juan Basin capacity by 105 MMcf/d.

El Paso’s White Rock Station will be down for controls replacement April 9-27, with the #1 turbine remaining down through April 29. Bondad Station will be down for annual Department of Transportation inspections April 16. The work will cut San Juan Basin capacity by 270 MMcf/d April 9-27 and by 105 MMcf/d April 28-29. Bondad capacity will be reduced by 585 MMcf/d on April 16.

Transwestern is conducting turbine meter cleaning and inspections on its San Juan Lateral. The work will limit New Mexico measurement points PNM/Blanco and TransColorado to maximum flows of 100,000 MMBtu/d each Thursday and WFS Kutz to 54,000 MMBtu/d Friday. Flow at Colorado measurement points will be limited to 200,000 MMBtu/d each at Northwest Pipeline Monday and at WFS Ignacio Tuesday.

Pacific Gas & Electric did not extend a high-inventory OFO beyond Saturday.

El Paso is investigating a vibration that developed in a turbine at Pecos River Station. Capacity through Pecos River was cut by 60 MMcf/d effective with Thursday’s Cycle 2 nominations until further notice.

Piedmont Natural Gas is planning to build a new pipeline to deliver gas supplies to Duke Power’s Mill Creek gas turbine electric generation facility, which is scheduled to go into service by June 2003. The peaking plant will use eight simple cycle turbines to generate 640 MW of power. It will be located in Cherokee County, SC.
