Remote Area Power Supply

To deliver energy to where you live, we want to offer practical and effective solutions that meet your needs.

In remote areas it’s not always best to simply replace an asset like an overhead line. To achieve a secure and reliable power supply, an off-grid solution such as Remote Area Power Supply (RAPS) can be a better idea. It’s also more cost effective for you and our customers overall.

A RAPS unit usually includes solar panels, battery storage and a diesel generator. So far, the Powerco team has installed 20 RAPS on our network and we will continue to do more. The positive impact can be seen in places like the Tangahoe Valley, where three units were installed in CPP – Year One and a further two are planned for CPP – Year Two. The new RAPS units replace the overhead power supply, which was constantly damaged in storms by trees and slips crashing through the lines. At times the destruction blocked the road for weeks, preventing contractors from reaching downed lines and poles. This was a major issue for the people who live there.

Now that RAPS are being used, storms will not impact on supply to our customers in these remote areas. They have proven to be a strong solution, at a far lower cost than re-building the 5.4km overhead line.

Our Challenge

Many parts of the Powerco network cover rugged, remote terrain, and are uneconomic to maintain.

Tangahoe is an example – the line into the valley has been rebuilt twice in the past nine years at substantial cost to service.

We needed a solution for a network trouble spot constantly damaged in storms by trees and slips crashing through the lines, – at times destruction blocked the road for weeks, preventing contractors from reaching downed lines and poles.

Our Solution

Our evolving Base Power technology provided the solution – replacement of the overhead supply in the network trouble spot with installation of five stand-alone, battery-powered units.  These produce electricity using a mix of solar and diesel generated energy.

While these battery powered units are a relatively new development for us, we have 20 in operation across remote sections of our network – customers are impressed with their reliability, particularly during storms.

The solar panels charge the storage batteries in each unit, with the diesel generator on standby if weather conditions inhibit solar generation.

What this Means

A more reliable and resilient power supply during stormy weather for the residents of the remote Tangahoe Valley east of Hawera
