LAHORE - The SNGPL has enhanced the duration of gas supply suspension to industries as well as CNG stations in Punjab owing to annual maintenance work at some gas fields. The gas supply suspension duration to industries was increased to three days from earlier one day while the supply to CNG stations will be suspended for two days in a week. The Sui Northern Gas Company Ltd (SNGPL) announced gas holydays by dividing Punjab into four zones. The gas supply will be cut on rotational basis to all four zones. The SNGPL authorities said that industrial sector has to face holidays due to annual maintenance work at Zam-zama Gas filed.

He added that start of winter season also increased shortfall of about 350mcf.

Similarly, all CNG stations of the province would remain close two days a week. He said the schedule of loadshedding will revisit after maintenance of Zamazam field. Zamzama Gas Field has the capacity of producing 500 million cubic feet of gas while its closure will affect the industries of Punjab mostly but the industries of Khyber PK will not be affected much with the closure, the source said.
