Combustion problems with the #2 engine at ANR‘s Grand Chenier (LA) Station are more extensive then originally thought (see Daily GPI, March 21), and the manufacturer has extended its estimate for completion of repairs until mid-April, the pipeline said. Volumes that can be received through Grand Chenier from HIOS and the West Cameron near-shore blocks will continue to be reduced by about MMcf/d until the repairs are finished.

Citing weather conditions, Gulf South postponed maintenance on its West 30-inch line (Index 129) north of Houston, which had been scheduled for today (see Daily GPI, April 2), until Thursday. The work is still due to start at 12 a.m. and last about 24 hours, reducing capacity southwest of the segment by 100 MMcf/d.

Tennessee reported being told by Dynegy Midstream Services, operator of the Yscloskey (LA) Gas Processing Plant, that effective today until further notice the plant will be operating in a “minimal processing mode.” Tennessee said it has determined that this will cause the formation of hydrocarbon liquids in gas delivered by the pipeline. Thus, starting today Tennessee will not accept any receipts on its 500 Leg with a heating value greater than 1,100 Btus/cf. “This will remain in effect until such time that the Yscloskey Plant returns to a normal processing mode,” Tennessee said. If this action fails to prevent formation of liquids in the line, effective upon notice for the next gas day, Tennessee will not accept any 500 Leg gas that “is not commercially free of hydrocarbon liquids (i.e., a hydrocarbon dewpoint greater than 20 degrees Fahrenheit).”

El Paso said high winds in the area of unscheduled repair have caused delays in returning to service part of Line 1103 between the Pecos River and Guadalupe Stations, preventing Pecos River capacity from reaching 900 MMcf/d as previously posted last week (see Daily GPI, March 28). However, throughput was raised to 740 MMcf/d in Cycle 2 nominations Monday. It will be increased to the full extent as soon as possible, the pipeline said. In addition, El Paso posponed pigging of Line 3199 near Waha Plant by one day to today through Friday. Line 3199 will be taken out of service and IVALEROW will not be able to flow gas to El Paso.

Pacific Gas & Electric had a customer-specific OFO in effect Sunday but did not extend it.

Northern Natural Gas began major repairs Monday on the Jal (NM) Station’s #2 compressor. The work, which will last through the end of April, is cutting about 35,000 MMBtu/d of capacity at the Sid Richardson Jal Lea receipt point, limiting it to 30,000 MMBtu/d, NNG said.
