New Zealand distributors eye grid upgrades as demand rises

TechnologyOne brought together leaders from New Zealand's electricity distribution sector for a roundtable on preparing for rising energy demand, with discussion focused on electrification and renewable generation.

Participants said distributors are entering a period of heavier investment as New Zealand moves toward wider electrification and a lower-emissions economy. Alongside network expansion, they are also facing tougher expectations around pricing, reporting, and long-term asset management.

Electricity distributors play a central role in the country's infrastructure, maintaining supply to homes and businesses while preparing for shifts in how power is generated and used. Severe weather and other disruptions have added pressure to strengthen network resilience.

The roundtable centred on recurring issues across the sector, including asset data, workforce skills, and investment planning. Together, these themes highlight the operational challenge of meeting higher demand without sharply increasing costs for consumers.

Dave Robertson, Chief Digital Officer at Unison, said: "These industry conversations are more critical than ever. Communities expect reliable service, regulators expect greater transparency, and the pressure to plan for future energy needs keeps rising. Meeting those expectations means making informed decisions about where we invest and how we continue delivering value for the people and businesses that rely on our network."

His remarks reflect the balancing act facing network owners. They must decide where to spend on upgrades and maintenance while preserving reliability and meeting scrutiny from regulators and customers.

Marlborough Lines also stressed the value of sharing views across the industry, particularly on common systems and processes. Collective input matters when distributors are working with the same software provider and facing similar planning demands.

Gareth Jones, Chief Financial Officer at Marlborough Lines, said: "It was great to get representatives from different electricity distribution businesses in the room together to discuss the TechnologyOne suite of products and share insights and learnings. Using a collective voice to drive future system development is crucial to ensuring that we're efficiently positioning ourselves to meet tomorrow's needs."

Common pressures

The issues raised at the meeting suggest many distributors are dealing with a shared set of pressures rather than isolated local problems. Asset condition data, workforce readiness, and long-range capital planning have become more important as electricity demand grows and the system becomes more complex.

One challenge is that electrification can increase demand unevenly, creating pressure in specific regions or parts of the network. That means distributors need a clearer picture of assets and usage patterns to target investment effectively.

Regulatory compliance is another growing area of work. Operators are being asked to provide greater transparency around spending, pricing, and long-term network decisions, increasing the need for stronger internal systems and more consistent data.

Technology role

TechnologyOne said the exchange of practical experience can help distributors decide where to direct money and staff time. For utilities dealing with long asset lives and complex maintenance cycles, those decisions can have effects that last for decades.

Ben Sheehan, New Zealand Country Manager at TechnologyOne, said: "Many of these challenges aren't unique to a single organisation. Whether it's asset data, workforce capability, or investment planning, there is real value in hearing how others have approached similar issues. These practical insights help organisations focus resources where they will have the greatest impact."

The discussion underlines a broader shift across New Zealand's electricity sector as distributors adapt to the demands of decarbonisation. Higher electricity use in transport, heating, and industry is expected to put more strain on networks, even as operators seek to integrate more renewable generation and maintain reliable service during periods of disruption.

For distributors, that leaves little room for short-term planning. Network resilience, disciplined asset management, and closer coordination across the sector are emerging as central concerns as New Zealand's electricity system adjusts to changing patterns of demand and supply.
