3. REGULATION 17: ENERGY DELIVERY EFFICIENCY PERFORMANCE MEASURES AND STATISTICS
3.1 Estimates, Assumptions and Adjustments
-
Gas flow figures have been extracted from the Quarterly Statistical Returns filed with the MED and the Statistics Department
-
The calculation of Total Amount of Gas Conveyed for Wholesalers or Retailers is based on the quantity of gas supplied to Welded Points controlled by a wholesaler, but excludes gas supplied to Welded Points directly supplying electricity generation facilities, petrochemical plants or gas production facilities. It is based on gas metered out of the system.
-
Total Amount of Gas Conveyed is gas metered into the pipeline system.
-
Negative Unaccounted-for gas means that more gas was metered out of the system than metered in after taking into account changes in the line pack inventory and gas used for compressor fuel.
-
The customer numbers are averaged over the relevant period as required by the Regulations. There were 8 customers at the end of 2006 and 13 at the end of 2007 – 2009.
