Gold Road Resources Limited (ASX:GOR) and Gruyere Mining Company Pty Ltd, part of Gold Fields Limited, reported a power expansion initiative at Gruyere Gold Mine (Gruyere). This is a 50:50 joint interest between Gold Road and Gold Fields.
Gold Field is a diversified global company that operates in Australia, Africa, Peru and Chile whereas, Gold Road is a tier-one gold producer and operates in Australia. Gold Road is having two sites in Gruyere which are under production. Amongst them, one is operated on 50 per cent (JV) interest with Gold Fields Ltd, while the other is fully owned by Gold Road.
On 8 December 2020, the JV inked a deal with Australia's leading energy infrastructure company APA Group (ASX:APA) for a multi-phase power expansion agreement at Gruyere Gold Mine, located in WA.
This is APA's first energy microgrid investment which involves a total capital of $38 million and will increase APA’s total installed capacity 45 per cent from 45MW to 64MW.
The initial phase of the project will include the expansion of Gruyere Power Station with the installation of a twelfth reciprocating gasfired engine. The second phase will consist of building and operation of a 13MWp solar farm backed-up by a 4.4MW/4.4MWh battery energy storage system.
APA's microgrid will use effective advanced systems ranging from cloud and weather forecasting, to battery and the reciprocating engine control systems to boost effectiveness and the utilisation of renewable generation. The overall blended carbon intensity of power supply to the Gruyere Gold Mine will be approximately 10% lower with the microgrid expansion, combining energy security with emissions reduction.
After the completion, APA will provide sustainable power support by battery stockpiling, supported by the dependability of gas-fired capacity to the Gruyere Gold Mine. Gas will be provided on a take-or-pay basis by APA's interconnected gas pipeline system.
The benefits include:
Work on the first phase is under progress and it is expected to complete by mid-2021, whereas the whole microgrid project is expected to be commissioned in Q4 2021.
This expansion project also compliments APA's recently announced Northern Gas Interconnected pipeline project incorporating the construction of 2,690 km of interconnected pipelines to enhance the ability to transport gas around WA from multiple basins thereby supporting the economy and creating job opportunities.
