On 15th February 2011 FGSZ published the natural gas quality accounting system (QAS) for the natural gas transmission system delivery points for the 2011-2012 gas year. Apropos of this, we have examined the changes in the weighted average calorific value of some selected delivery point.
QAS is the method of quality accounting system of delivered natural gas through the delivery points of the gas transmission system network, valid for a calendar year.
