Golden Plains Wind Farm

WestWind Energy are proposing a 1.3-gigawatt (GW) wind farm and 300 megawatt-hour battery storage system across more than 16,000 hectares at Rokewood in Victoria's Golden Plains Shire. The project is likely to be the largest wind generation project in Australia. 

The project scope includes: 

  • 215 turbines with a tip height of 230 metres 
  • four substations 
  • up to six permanent meteorological masts
  • terminal substation connected to the Melbourne-Portland 500 kilovolt transmission line
  • 150 kilometres of internal access roads, and 
  • a quarry for the production of crushed rock products required for the project’s construction.

The project will be delivered in two stages. Stage one will include the first 122 wind turbines.

PROJECT HISTORY

Jul 2016 WestWind Energy conducted feasibility studies at the Rokewood site.
May 2018 The project's Environmental Effects Statement (EES) was placed on exhibition until 18 June.
Oct 2018 The Victorian Government provided conditional approval for the project in its assessment of the project's EES. The project was approved on the basis that the proponent reduce the quantity of turbines from 228 to 181 to protect Brolga breeding wetlands.
2021 WestWind Energy submitted a Planning Permit Amendment in response to the government's assessment of the EES. The amendment included modification of the site plan, including reduction to 215 turbines and moving of associated infrastructure to comply with the Brolga Breeding Buffer permit condition, amendments to the Brolga Monitoring and Compensation Plan condition, administrative correction to the flood event surface water level condition, and increasing turbine rotor diameter from 150 metres to 165 metres.
Nov 2021 The Victorian Government approved WestWind Energy's Planning Permit Amendment in full.
Feb 2022 WestWind Energy announced they secured equity financing and awarded the Engineering, Procurement and Construction (EPC) contract for the project. TagEnergy will be the majority equity investor and operate of the wind farm. Vestas was awarded the EPC contract and long-term service and maintenance contract under a 30-year term. WestWind Energy also announced project scope changes. The project increased generating capacity from one gigawatt to 1.3 gigawatts. In addition, the project will include a 300 megawatt-hour battery storage facility. These scope changes have increased the total cost of the project from $1.7 billion to $3 billion.
