Your Energy Future

Powerco brings power to your door. You buy electricity from your retailer, and we look after the local network lines, cables and other equipment that deliver it to you.

Providing a safe and reliable supply of electricity to all those that live, visit and work in the Coromandel region is what we’re here to do. We make sure you have the power you need, when you need it.

Shoring up your power supply in the Coromandel region

With more people choosing to live and visit the Coromandel region, comes a much greater demand for power. This means there are now times during the year – mainly public holidays and long weekends – when the level of demand is greater than our network was originally designed to deliver.

There’s now a chance of losing power during these times of peak demand, and this will increase as the region’s electricity demand continues to grow.

We know that there’s never a good time to be without power. That’s why we’re working towards a solution that will support your community’s power supply into the future, peak times included.

Back in 2017, our team considered options and identified that a traditional approach, which would involve building new overhead power lines to increase the capacity of our existing network, would address the issue.  

The timing is now right to address the issue and we want to ensure that it aligns with your community’s priorities, particularly given there are other options available, which don’t necessarily involve putting up more poles and wires. From our discussions with the communities we serve over the last few years, we believe that customers want the lowest cost solution, that in addition meets reliability expectations and has the least impact on the environment.

If these priorities are shared by the Coromandel community, there is an alternative to a traditional (poles and wires) approach. This is the installation of modern diesel generators in three site locations: Whitianga, Matarangi and Coromandel Town. These would provide a back-up supply that will kick into action to keep the power on, but only in the event it is needed. In fact, the total time the diesel generators would be expected to run for the three areas is a maximum of eight days. This means the environmental footprint is low and can be installed quicker than other available options.

Using this type of generation means we can continue to deliver a safe and reliable power supply to your community at the lowest cost to you.

While we believe that diesel generators are the best option from a cost, reliability and environmental perspective, we’re continuing to explore other alternatives at the same time. This will make sure we deliver the solution that best meets these needs.

Survey question

When identifying a solution, we have considered options from a cost, network reliability and environmental impact perspective, as we believe these matter most to you.

The diesel generator solution would meet the network needs at the lowest cost (approx. $10m and saving $20m over the traditional network solution) and, we think this option has the least impact on the environment as a result of the minimal planned running times (up to approximately eight days a year for the three sites).
