Granville Harbour Wind Farm

CONTEXT

Granville Harbour Wind Farm (GHWF) is a 112 MW wind farm, located 25 km north-west of Zeehan, Tasmania which connects to the 220kV transmission network via a new Pieman Switching Station and an 11 km transmission line. Granville Harbour Operations Pty Ltd (GHO), as trustee for Granville Harbour Operations Trust, is the owner of the project and had engaged Vestas as the Engineering, Procurement and Construction (EPC) Contractor to undertake these works in full on its’ behalf.

EMBRACING COMPLEXITY

The GHWF is a highly complex project due to its location, scale and technical requirements. The GHO team that Ekistica managed included the owner’s engineers, communications team, environmental services and administrative staff. A high level of communication and logistics needed to be understood and disseminated between GHO staff and coordinate engagement with the EPC Contractor.

GHO lead engagement with Commonwealth, state and local government agents monitoring the EPC Contractor’s obligations under all levels of legislation. Furthermore, GHO have proactively engaged with State Emergency Services including Tasmania Police, Fire fighting services and State Emergency Services (SES).

For the whole of the construction phase, Ekistica were contracted to provide project direction, management, owner’s engineering and contract administration services.

Ekistica continue to service the Granville Harbour Wind Farm on behalf of the Owners with Commercial Operations achieved. Key tasks are as follows as per the EPC contract that was executed for this project:

• Defects and Outstanding Works List (DOWL) including both geolocated (physical defects such as potholes) and non-geolocated defects (documentation such as As Built drawings). .

• Weekly EPC meeting with Contractor. Typically including safety issues, outstanding actions by Contractor and key stakeholder engagement for example TasNetworks and AEMO.

• Completion of all other responsibilities that vary between document management and handover is completed, quarry mine licence arrangements and finalisation of key contracts managed throughout construction.

The completion of Granville Harbour Wind Farm resulted in Tasmania being able to achieve its goal of producing 100% of its energy from renewables.

“The wind farm’s 31 turbines
produce around 400,000 gigawatt
hours of clean, renewable energy
every year. This is enough electricity
to power around 46,000 homes –
almost every household in the North
West of Tasmania.”
