New Zealand utility partners with Itron to monitor low-voltage system


Itron has been selected by New Zealand utility Network Waitaki Limited to help the energy provider improve management and operation of its grid network.

Network Waitaki Limited (NWL) will implement Itron’s distribution transformer monitoring (DTM) solution to provide better quality of service to 13,000 customers through access to real-time data regarding the operations of transformers.

Additionally, NWL will use Itron’s cloud-based Software-as-a-service applications to operate the DTM solution.

Tod Trotman, planning and asset manager at the utility firm, said: “With Itron’s solution, we will be able to increase our network awareness, especially at the low voltage level, improve outage management and harness detailed asset analysis.

“The solution will give us the ability to optimise our capital investments and improve system reliability, so we can increase customer satisfaction and take advantage of our transformer assets.”

However, the utility will continue using a SCADA system to access operational data of grid assets within its high voltage network, which is comprised of 2,000 km of power lines.

The DTM will help the utility to quickly identify or avoid outages on the low-voltage system, improve maintenance and extend the lifetime of transformer assets, calculate transformer load and collect and store data.

The decision to implement the DTM at full scale follows a successful pilot which was started in 2016. The pilot included installation of eight DTM units.
