Transmission revenue
Transmission revenue consists of charges for the transmission of electricity from the point of generation to the point of supply, being high voltage alternating current (HVAC) interconnection, connection and high voltage direct current (HVDC).
The Lines Business operates its revenue setting methodology within an Economic Value ("EV") framework that analyses economic gains and losses between those attributable to shareholders and those attributable to customers. The balance of the accumulated gain (loss) from regulated transmission activities attributable to customers ("the EV balance") is passed on to or claimed from customers over time as EV (rebates) or charges.
Customer investment contracts are contracts entered into with customers to build grid connection assets.
Other transmission revenue was higher in 2011 due to the sale of copper from the dismantling of the old transmission line on the North Island Grid Upgrade (NIGU) route.
