Vector, the Auckland energy network owner, would have to accept a 25 per cent cut to its transmission charges for gas pipelines under proposed default price-quality paths proposed by the Commerce Commission.
The regulator has released the proposed changes which would establish the biggest adjustments that would start on July 1 next year. After that, prices would be adjusted by the rate of inflation through until 2017, it said in its revised draft decision.
Vector has been battling the changes with a court challenge. The changes provide some winners and some losers. Powerco, for example, could raise prices in its distribution by 5 per cent.
Vector's distribution prices for its Auckland network would be cut by 16 per cent, while GasNet would face a 2 per cent distribution cut and Maui development would enjoy a 2 per cent transmission increase.
For customers of Vector, the reduced distribution charge would amount to a $4.60 cut to the monthly bill for the 143,602 residential gas users in Northland, Greater Auckland, Waikato, Bay of Plenty, Rotorua, Taupo, Gisborne and Kapiti. Powerco's users would face a 60 cent increase and those of GasNet in Wanganui would enjoy a $1.10 decline.
