With more retailers managing load across electricity distribution networks, the sector needs a common approach for how load is managed during network and grid emergencies.
If each network followed different rules, it would increase complexity and the risk of error — particularly during time-critical situations. A consistent approach helps ensure electricity continues to flow reliably to homes, businesses and communities across Aotearoa.
A coordinated approach to managing load
We worked with ERGANZ (Electricity Retailers’ and Generators’ Association of New Zealand) to develop a common load management protocol, building on initial work led by our Future Networks Forum.
Load management includes hot water control and any other controllable load such as electric vehicle chargers. Having a common protocol will help:
- ensure a coordinated response during emergency situations
- reduce confusion and operational risk across networks
- support a reliable electricity supply for consumers.
All lines companies and retailers can adopt the protocol and apply it when required. The core terms provide a consistent national framework, while still allowing each lines company to develop specific schedules that reflect the characteristics of its local network.
If adopted by lines companies and retailers, the protocol will work alongside and support the requirements of the Default Distributor Agreement (DDA).
Developed with sector input
The original protocol was developed by the Future Networks Forum, with input from across the electricity sector. Following feedback from retailers about their current systems, customer agreements and operational capabilities, we worked with ERGANZ to develop a revised version (v2.0).
The revised protocol reflects what lines companies and retailers can put into practice now, while retaining a common approach to managing load during emergencies. It also provides an opportunity to review and strengthen the arrangements as technology and systems develop.
Version 2.0 — current version
Version 2.0 is the current version of the common load management protocol (sometimes referred to across the sector as the LMP). We recommend that lines companies and retailers use v2.0 as the basis for agreeing load management arrangements with each other.
The protocol, including the data sharing arrangements, is available as a single document in both PDF and Word formats.
- Common load management protocol – version 2.0 (PDF)
- Common load management protocol – version 2.0 (Word)
Version 2.0 has been developed jointly by ENA and ERGANZ. Formal endorsement will be sought at the next ENA Board meeting.
An evolving framework
The protocol is not set in stone. As the electricity system evolves and more controllable technologies connect to the network, the framework will continue to develop.
Version 2.0 includes an initial 12-month period for lines companies and retailers to gain practical experience using the protocol. Following this, we’ll work with ERGANZ to coordinate a review to identify what is working well and where further improvements may be needed.
Previous version (for reference)
The original version of the common load management protocol (v1.0) is retained below for reference only. Version 2.0 is the recommended version for new agreements.
