A look at SNGPL- SSGCL performance

Engineering Post Report

Domestic  natural gas production target was fixed at 1.47 million  cubic feet for the financial year 2021-22. The gap in the indigenous  gas production  was planned to be supplemented  through import of Liquefied  Natural Gas (LNG).

For the financial year 2020-21, target for domestic natural gas production was fixed at 1.43 trillion cubic feet against the achievement by end June 2021 was 1.27 trillion cubic feet i.e. 89 per cent. It has been more than once  been stated officially  at the appropriate highest level that natural gas domestic production is decreasing on average by 9 per cent annually and no new gas reserves discovery  has been made for quite some time.

According to some facts and figures available regarding performance of the two national gas entities, the Sui Northern Gas Pipelines Limited (SNGPL) and Sui Southern Gas Company Limited (SSGCL) have collectively  repaired  around 887 kilometer faulty pipelines  and rectified large number of 1446342 leakages  in  line with the strategy of the federal government for bringing down the Unaccounted For Gas (UFG) ratio.

Furthermore, experts of both the national gas entities are reported to  have inspected  around  as many as 13388 Town Border Stations and rectified 633  of these stations after finding them leaking, according to an official document.

SNGPL and SSGCL both have installed Electronic Volume Corrector (EVC)  meters at all industrial connections and high pressure commercial connections for calculating actual volume of gas consumption, maintaining  record of hourly/daily gas consumption   and generating  tamper alarm  in case of an attempt being made    for magnetic interference with meter or other  infrastructure.

Around 1850 out of 3655 industrial connections have so far also  been integrated with  Supervisory Control and Data Acquisition (SCADA)  for remote monitoring  of industrial consumers  for  ensuring timely  identification of gas theft and measurement error, if any.

In order to effectively check and control the line losses and lowering UFG ration, the cyber locks are being  installed at the  industrial meter  stations in order to restrict the access of the industrial  consumers to the meters and regulators for reducing the chances of gas theft. Both SNGPL and SSGCL  are also using  Laser Leak Detectors, the best available technique and gadgets,  for identification of underground leakages.

The UFG losses of both the gas entities i.e. SNGPL and SSGCL  stood at 8.83 per cent and 15.85 per cent  respectively during the financial year  2020-21. According to the information contained in the official document, volumetric loss of  SNGPL had remained 34021 million cubic feet (MMCF) of  gas and of SSGCL  at comparatively higher level of 67476 MMCF of gas  mainly because of gas leakages, measurement errors as well as theft.

During the financial year 2019-20, the SNGPL and  SSGCL had prevented a volumetric loss of around  9938 MMCF  against the UFG  reduction target of 14806  MMCF gas. The UFG is a phenomenon  of gas loss that occurs due to various technical  factors  when gas  flows from the fields to the end consumers across the country. It is , as such, calculated as the difference between the metered  gas volume  injected  into the transmission and distribution network i.e. Point of Dispatch/Delivery and the metered gas  delivered to the end consumers i.e. Consumer Meter during a financial year.

During the financial year 2020-21, SNGPL  was to add 405450 gas consumers including  domestic, commer4ciak and industrial consumers. Against this, the achievement on the whole was 262206   giving a performance ration of only 64.67 per cent. Quite interestingly, against target of provision of gas connections to 450 industrial consumers, SNGPL could only provide gas connections to 52 new industrial consumers  which worked out to be just 11.55 per cent of the target.

SSGCL was to add 125245 all categories of new consumers during the period report against which gas connections could only be provided to 70687  new domestic , commercial and  industrial consumers giving over all percentage of 56.43. SSGCL also failed to even provide gas connections to 167 new industrial consumer, as per the target , during the financial year as only 65 new industrial connections were added giving a percentage of 56.43,  comparatively much better than SNGPL.

SNGPL target of all categories of new consumers during financial year2021-22 was 1200000 and that of SSGCL 133938 .

In terms of transmission and distribution, both the  national gas entities failed to achieve even 50 per cent of the target. SNGPL was to extend transmission and distribution network by 6291 kilometers against which the achievement was only 2947 kms  i.e. 46.84 per cent. Likewise, SSGCL was to extend its transmission and distribution up to 1206  kms against which the achievement was  49.17 per cent. During ongoing financial year 2021-22,  SNGPL ‘s target for expanding its transmission and distribution system is 17060 kms and that of SSGCL it is only 1671 kms.
