Overview

As part of the Waikato and Upper North Island voltage management (WUNIVM) investigation, Transpower has identified the need to install Dynamic Reactive Plant (DRP) on Otahuhu (OTA) 220 kV bus and Hamilton (HAM) 110 kV bus (refer to Figure 1 above). The primary purpose of the DRP is to maintain voltage stability in the WUNI region. The key risks are transient (i.e. very fast occurring) and include both under- and over-voltage effects. The DRP would be expected to inject or absorb variable amounts of reactive power in a few milliseconds to maintain the voltage stability.
The DRP will be supplied, installed and commissioned under a design and build contract. Transpower will be responsible for making all aspects of the sites ready for installation of the DRP through a separate enabling works contract for civil and electrical work. This enabling works contract will require an early provision of design information from the supplier. The supply of the DRP is subject to approval by the NZ regulator, which is expected in mid-2020.
