Project Overview

Sandfire Resources’ DeGrussa solar farm and battery energy storage system is at the end of its current off-take agreement. Neoen selected Westforce to manage the decommissioning and rehabilitation of the DeGrussa Solar PV Hybrid Project in Western Australia’s goldfields region.

The project comprised of a 10.6 MW single-axis tracking solar power plant paired with a 4 MW lithium-ion battery storage system.

Project Scope

Westforce’s scope of work included decommissioning, dismantling, and packaging of the solar farm and battery storage facility.
This involved the following:

Delineation of work areas
Isolation and disconnection of existing electrical services from the mine power plant
Disconnection of solar panel electrical feeds, DC boxes, and inverter stations
Removal of solar panels, single-axis tracker, array posts, inverter stations, and BESS components
Removal of inground conduits and cabling within the solar farm boundaries
Removal of existing infrastructure such as fencing, dome structures, containers, piles, and miscellaneous materials
Rehabilitation of the existing ground
Loading and transportation of all decommissioned components
