Planning for resilience through Aotearoa New Zealand’s energy transition

Aotearoa New Zealand’s energy debate has become urgent. As domestic gas supply tightens and pressure in global fuel markets continues, energy security has become a growing focus of public discussion. The conversation is often framed as a binary choice between storable fossil fuels as a near-term hedge against supply risk, versus accelerated electrification with a faster shift to renewables.

That framing oversimplifies the choices in front of us. The question is how New Zealand can build an energy system that stays reliable through transition, supports industry through change and keeps long-term decarbonisation moving. That calls for a clearer decision framework, grounded in system resilience, industrial reality and the pace of infrastructure delivery.

New Zealand is not starting from scratch. Our electricity system already operates with a high renewable share in a typical year, and a substantial pipeline of renewable generation and storage is under development or in construction. Electrification and fuel switching are also under way across parts of the economy where the pathway is viable. Those strengths should shape long-term planning.

They do not, however, remove current exposure. Domestic gas decline is now an operating issue for many businesses. The closure of the Marsden Point refinery has also changed the profile of fuel security by increasing reliance on imported refined fuels. In that setting, energy resilience is no longer a narrow policy topic. It sits inside investment decisions, operating plans and wider confidence across New Zealand’s productive economy. 

This is where the discussion requires more discipline. New Zealand needs to keep expanding renewable generation and support grid investment. The fast-track consent process may help some projects move forward, but progress will still depend on how quickly supporting infrastructure can be delivered.

Those issues are well understood. They should remain central to the national response because a larger renewable base improves resilience over time and reduces structural exposure to imported fuels.

However, long-term direction is not the same as short-term readiness. The government needs to set out a clearer pathway for the energy system, with a realistic view of how renewables, domestic gas, coal and liquefied natural gas (LNG) may each shape the transition that is needed.

That is especially true for LNG. In some discussions, it is presented as a simple answer. In others, it is dismissed outright. Any case for LNG should rest on transparent assessment. Commercial structure, contribution to supply, infrastructure requirements and timing all matter. So does the impact on industrial users, driven by the price and availability of fuel. 

Many of these businesses support essential supply chains or provide significant regional employment. Most are already considering their pathway to electrification, biomass or other lower-emissions alternatives. Yet the practical barriers are often substantial. Site operational constraints, capital availability and network readiness all shape what can happen and when.

The challenge is, therefore, more complex than a single expectation that gas users should transition to alternative fuels. Alongside clearer government direction, businesses also need a realistic view of their exposure to the energy transition. Supply challenges in the energy market are unlikely to ease quickly. That raises the value of structured planning around cost, supply risk and readiness for future energy disruption.

Many businesses in New Zealand are already working through what this transition means in practice. For some, that includes fleet electrification or shifting light-duty operations to electric vehicles. For others, the focus is process heat, with options such as biomass, biogas or alternative liquid fuels under consideration where electrification is not yet viable. The commercial reality also needs to be tested, including the energy price levels or carbon settings at which those pathways become workable.

Others are only beginning to define a structured approach to manage their energy needs. As conditions in the energy market remain unsettled, having a clear strategy is becoming an essential part of maintaining operational stability, and there is growing experience across the market to draw on. 

Local and international experience suggests that decarbonisation is rarely delivered through a single fuel choice. In Europe, Asia and Australia, transition pathways are being shaped through a combination of hydrogen and its derivatives, renewable natural gas, biofuels and electrification supported by the use of transitional fuels. Each is assessed against clear criteria such as cost, emissions intensity, supply chain availability and delivery timing. That creates more discipline in decision making, with fuel switching treated as a staged transition aligned to infrastructure readiness and industrial constraints.

The government’s energy strategy will shape the direction of the market, but the response from businesses matters as well. The pressures facing the energy system are unlikely to be resolved quickly. Organisations will need to take a more deliberate view of how their energy needs evolve over time, helping them navigate uncertainty throughout the period ahead.

As the transition continues, we will keep working alongside industry to support more informed, structured approaches to energy decisions, helping organisations respond to change with greater confidence
