1. As at 30 June. 2. Net number of customers added during the period, includes disconnected, reconnected and decommissioned ICPs. 3. SAIDI minutes for the regulatory year – 12 months to 31 March (audited). 4. Normal Operations (SAIDI) includes the impact of 1 Major Event Day (MED) resulting in 6.371 SAIDI minutes capped to 3.374 minutes. 5. This is the SAIDI amount over and above the MED cap for the Major event days in aggregate. 6. Billable ICPs. 7. Excludes gas sold as gas liquids. 8. The group completed the sale of its interests in the Kapuni Gas Treatment Plant (KGTP) and co-generation facility on 31 March 2020. As a result, we have changed the methodology of calculating liquids volumes to reflect continuing activities only. LPG volumes include LPG sold by the OnGas business. LPG and Natural Gasoline sold by KGTP is now excluded. Comparatives have been restated to reflect this. 9. Number of 9kg LPG bottles swapped and sold during the year. 10. The group has revised the methodology for Liquigas LPG tolling to reflect new contractual terms and calculates product tolling domestic and exports. Product further tolled in South Island has been removed. 11. The number of advanced meters as at 30 June 2020 includes 168,793 meters managed but not owned by Vector (30 June 2019: 156,713).
