Tararua Wind Farm
Client: TrustPower and Vestas DWT
Parsons Brinckerhoff Role: Engineer-Procure-Construct Contractor; Consultancy Services
Parsons Brinckerhoff has had extensive involvement since 1992 establishing this 68-megawatt (MW) wind farm, among the largest in the Southern Hemisphere. Parsons Brinckerhoff’s involvement began with the identification of the site for a local power company, CentralPower (subsequently acquired by TrustPower). Following Parsons Brinckerhoff’s initial work, the company had an active and integrated involvement in forming different teams responsible for ensuring the economic viability of the development in a non-subsidized electricity industry, where individual power projects have to compete against existing and new power projects.
The firm’s involvement progressed from the initial wind-monitoring program, to supplying consultancy services to develop the environmental consent application and providing expert witnesses to the Consent Authorities hearings.
Phase I (48 turbines) were installed and operating by 1999. Phase II construction of another 55 wind turbines commenced in June 2003 and was completed by May 2004. For Phase I, Parsons Brinckerhoff was the engineer-procure-construct contractor to Vestas DWT and was responsible for the design and installation of towers and foundations. For Phase II, Parsons Brinckerhoff prepared contract documents, undertook micrositing and energy assessments, and was the overall construction and project manager, managing the four separate contracts on behalf of TrustPower.
Upon completion of Phase II, a total of 103 wind turbines had been installed.
