Modest, steady growth has characterised Aotearoa New Zealand electricity demand over recent decades. The response has been a regulatory and investment system that incentivised just-in-time investment, not overbuilding to protect consumers that bore the costs of investment.

The need to meet legislated emission reduction targets, as well as emerging technologies and changing consumer preference, has led to a rapid acceleration in the electrification of transport and industry.

Our electricity sector is currently served by a large asset base, with substantial upcoming renewal requirements. Decarbonisation, through electrification, has created a meeting of tides from a network investment perspective. New Zealand’s current way of enabling investment is no longer fit to meet a challenge of this scale.

In this report we cast a spotlight on a range of solutions, involving both the public and private sector, to address emerging challenges for network finance.

    Within system changes

    The system must support the step change in energy use. Changes to the current settings may involve permitting greater allowable revenue, or greater flexibility to change revenue allowances.

    Private capital

    Private capital could take a larger role in electricity distribution to alleviate the risk of underinvestment. Greater involvement could take the form of traditional debt or equity raises by existing providers, or a blend of these options using Special Purpose Vehicles.

    Public capital

    Public finance may offer a bridge across the uncertain future, with various tools available to government. The form of Crown support would depend on the extent of control the Government wishes to have over the electricity networks of the future.
