Citing forecasts of cold weather in market-area Zones 5 and 6 limiting its operational flexibility to manage imbalances, Tennessee said it implemented an Imbalance Warning in those zones at the start of Friday’s gas day. All affected delivery point operators were required to keep actual daily takes out of the system equal to or less than scheduled quantities regardless of their cumulative imbalance positions, while receipt point operators had to keep actual daily receipts into the system equal to or greater than scheduled quantities regardless of their cumulative imbalance positions.
In order to minimize shipper impact, CenterPoint said it has determined that about 13 days of turbine maintenance previously scheduled to begin Tuesday at Perryville Compressor Station (see Daily GPI, Oct. 26) can be postponed until next spring without impacting system reliability. CenterPoint also said late Thursday it anticipates no capacity impact at this time from a series of integrity digs in Arkansas between the towns of Malvern and Helena that will begin Monday and last about 10 days. But if necessary, an announcement of a capacity reduction could come on short notice, the pipeline added.
