Waipara - Kaikoura 66kV Re-Insulation Project

In July 2005, MainPower commenced a three year project to re-insulate the existing 33kV line between Waipara and Kaikoura to 66kV. This key capital project has been broken down into two major stages, with Stage 1 covering from Waipara to Cheviot and stage 2 covering from Cheviot to Kaikoura. Complete with over 475 steel extensions being erected and 130 poles changed to allow the new 66kV insulators to be installed.

66kV

Stage 1 of the 66kVA line project and installation of sub stations was completed early November 2007. The livening of the three new skid substations located at Mackenzie Road, Greta Valley and Cheviot were undertaken over a 6 day commissioning period, requiring the utilisation of the 1,250kVa generator to 80 extensions (budget 316), 40 strain poles (budget 178) and 90 in line poles (budget 331) ensure the surrounding districts were not affected by the shutdown of the sub stations.

Stage 2 of the project begin during 2007 with the 66kV line construction Project (Cheviot to Kaikoura) 25% complete at the end of 2007 with 209 of the 836 structures changed. The line construction should be completed in 2008. MainPower Contracting has established a dedicated project team and purchased specialised equipment to undertake the project.The upgraded line will ensure MainPower has a security of supply to Kaikoura without relying on the existing line via TransPowers circuit.

Stage 2

Conversion Project

This project involves the conversion of 13km of 11kV distribution line to 22kV in the Motunau, Greta, Leader and Claverly areas. The Motunau to Greta region will be undertaken in association with Stage 1 of the 66kV re-insulation project with the Leader to Claverly area being undertaken in 2008.

Pegasus Township Power Reticulation

MainPower has been engaged by the Infinity Group to provide power reticulation to the new Pegasus Township. The project will span approximately 3-4 years and will see the power reticulation being installed for the new township.The project commenced in June 2007 with a dedicated project team being established to provide the installation of the underground cabling and installation of the streetlight network.MainPower has developed a solid working relationship with Heb March, the projects civil contractor, which has seen the completion of the Mapleham entrance way and Stage 1 of the township completed in November 2007 although delayed somewhat on the original project time frames.
