| Maximum monthly amount of gas entering system (GJ)⁵ | 2,287,144 | 2,406,065 | 2,458,233 | 2,530,123 |
| Total annual amount of gas conveyed through system (GJ)⁵ | 22,117,219 | 22,597,621 | 23,306,357 | 24,093,632 |
| Total annual amount of gas conveyed through system for persons not in a prescribed business relationship (GJ)⁵ | 11,999,196 | 12,012,132 | 10,156,387 | 11,467,489 |
| Total number of customers | 145,122 | 140,872 | 136,769 | 132,527 |
⁵ The methodology used to calculate the amount of gas (GJ) that was disclosed for 2005 through 2007 for Vector’s non-controlled (NGC) distribution business was amended in 2008 to provide a consistent methodology across Vector’s total distribution business. The previously disclosed figures have been adjusted to provide a consistent basis for comparison; this has necessitated minor adjustments being made to the corresponding values for load factor and unaccounted for gas ratio. The amount of gas (GJ) that was disclosed for 2005 for persons not in a prescribed business relationship has also been adjusted to reflect Vector’s partial acquisition of NGC and its gas retail business during the period. The previously disclosed figures were as follows:
| 2007 | 2006 | 2005 | |
|---|---|---|---|
| Load factor | 78.09% | 79.10% | 79.99% |
| Unaccounted for gas ratio | 1.41% | 1.36% | 1.29% |
| Maximum monthly amount of gas entering system (GJ) | 2,383,459 | 2,425,488 | 2,481,916 |
| Total annual amount of gas conveyed through system (GJ) | 22,335,868 | 23,022,375 | 23,823,990 |
| Total annual amount of gas conveyed through system for persons not in a prescribed business relationship (GJ) | 10,507,493 | 9,983,381 | 15,324,017 |
⁶ NGC service pipeline length included in System Length (km) disclosure for 2006, 2007 and 2008, but excluded from 2005 disclosure due to lack of data.
