Name and Location
DeGrussa solar power plant project, Australia.

Client
juwi Renewable Energy will develop and operate the project. French renewable-energy firm Neoen will own the facility.

Project Description
The DeGrussa solar power plant will be the largest integrated off-grid solar and battery storage facility in Australia, and one of the world’s largest integrated solar installations that will provide peak load power for a mining operation.

The project comprises a 10.6 MW solar array using 34 080 solar photovoltaic (PV) panels over 20 ha.

It uses single-axis tracking technology, combined with 6 MW of short-term battery storage, and will be located near the site of Sandfire Resources’ DeGrussa underground mine and 1.5-million-tonne-a-year concentrator, about 900 km north-east of Perth, in Western Australia.

The solar facility has been designed to provide the bulk of Sandfire’s daytime electricity requirements, offsetting about five-million litres of diesel fuel a year and abating more than 12 000 t/y of carbon dioxide.

The solar power station will be fully integrated with the existing 19 MW diesel-fired power station at DeGrussa, which is owned and operated by Pacific Energy subsidiary Kalgoorlie Power Systems (KPS).

This integrated system will be designed with the diesel power station continuing to provide baseload power for the DeGrussa mine, with sufficient minimum load to ensure it can respond quickly to meet the power requirements of the process plant and underground mine.

Agreements have been completed with KPS for the integration of the solar power facility.

Value
The project is valued at an estimated $40-million.

The Clean Energy Finance Corporation (CEFC) is committing up to $15-million in finance for the project, while the Australian Renewable Energy Agency (Arena) is providing $20.9-million in funding, with Neoen contributing most of the balance.

Sandfire’s cash contribution to the project will be less than $1-million.

Duration
Construction activities at the DeGrussa mine site started in July 2015, with the facility expected to be fully operational in 2016.

Latest Developments
The DeGrussa solar plant has been successfully commissioned and has started providing electricity to the DeGrussa copper and gold mine.

The solar plant is generating 7 MW of electricity, and will ramp up to 10 MW in the summer months.

Testing has confirmed that the plant could perform in accordance with contractual specifications and validated the power purchase agreements (PPAs) covering the facility. Continual testing will be completed this month to ensure it can maintain stable operations at 100% generation capacity.

Commissioning of the $40-million project started in March following installation of the last of the 34 080 solar PV panels. The panels have a single-axis tracking system mounted on 4 700 steel posts, enabling the panels to track the sun during the day.

Key Contracts and Suppliers
Sandfire (PPA), CEFC and Arena (finance).

On Budget and on Time?
The overall construction schedule for the project is on track for delivery of first electricity from the facility during the first quarter of 2016.
