NZ’s Electricity Future

If you read nothing else on New Zealand’s Electricity future, read these three essential documents.

They show why there will be a rapid uptake in electrification, including significant increase in consumer energy resources  by the average consumer. Why the electricity system needs to change to enable those resources to be part of an optimised energy environment and the steps we need to take to implement that solution. 

Electric Homes

The report highlights that households currently reliant on gas appliances and petrol vehicles stand to save approximately $1,500 annually at prevailing interest rates. This saving could surge to about $4,500 annually if these households switch to electric alternatives, leveraging a low-interest loan and sourcing electricity from a mix of rooftop solar, home batteries, and New Zealand’s predominantly renewable power grid.

Such significant financial benefits are expected to motivate consumers towards electrification, regardless of whether electricity distribution networks are equipped to handle the change. The anticipated surge in adoption within New Zealand could mirror the extensive adoption of home solar systems in Australia, propelled by government subsidies. It is hoped that New Zealand will better anticipate and prepare for this grid-edge revolution than Australia managed to do.

Price discovery in a renewables based electricity system

The Market Development Advisory Group’s findings emphasize the necessity for the New Zealand electricity sector to gear up for electrification. An estimated investment of $27 to $37 billion in demand-side flexibility (DSF), batteries, and new generation is required by 2050 to address the increasing power demand. Strategic investments made timely and at the right locations can yield significant benefits. The contract market, pivotal in signaling investment directions, needs enhancement to provide more detailed information about the value of investing in flexibility for both demand and supply aspects of the system. Advances in metering, sensors, and data processing technologies are simplifying the process for consumers (or their devices) to adjust their electricity demand actively. Ensuring the wholesale market design supports full participation from consumers eager to benefit from active demand response is crucial.

Flexibility Plan 1.0

The Flexibility plan is essentially a blueprint designed to kickstart a joint effort to harness the potential benefits of distributed energy resources (DER) for everyone—households, businesses, communities, and the overall power system in Aotearoa New Zealand. It acts as a dynamic guide, outlining specific actions needed from various perspectives, including those of consumers, whether they use DER or not. The goal is to lay out a path for evolving the electricity system to better utilize flexible energy sources.
The Plan is acknowledged as a work-in-progress; it’s the initial phase in an ongoing process. It includes a set of actions that will be continually refined, expanded, and marked as completed based on experiences and lessons learned. The aim is to evolve this Plan into a more advanced version, Flexibility Plan 2.0, by September 2024.
Achieving the objectives laid out in the Plan will be a long-term endeavor, demanding collaboration and input from all parts of the electricity sector.
