Mark Ryall, Transpower

As a paper mill, construction of an 11 kV overhead line is not our forte. The engineering design and the on-going support we received from Edison, ensured that our project was completed on time.

This was a complex and challenging project involving a great deal of coordination not only between the substation team, but also the cabling crew working on the wider NAaN project. I was impressed with the professionalism demonstrated by Edison in managing the various components of this major project which is critical to the security of supply into the North Shore and beyond.

Brett Stark, Transpower

This was a complex and challenging project involving a great deal of coordination with many different parties. Edison provided valuable technical support in the risk mitigation, testing and commissioning phases of this project and played a key part in this final phase of the mobile substation project.

The delivery of this project, which had high importance for customers in the area, would not have been a success without the contribution of Edison’s project management knowledge and experience.

Stephen McAdams, Transpower

The project had already commenced and it was becoming evident that additional resources would be required to assist the project team to ensure the project was delivered on time and on budget. Within two days of us making this decision Edison were able to provide Project Management support which was able to deliver immediate onsite technical support and supervision of the line build contract. This ability to react so swiftly and effectively impressed both Meridian and the Alliance Leadership Team and instilled confidence in our ability to ensure WEL’s commitment to deliver the entire project would be met.
