Santos DLNG, Darwin, Northern Territory
Electricity network, substations, solar and BESS
Santos is considering the electrification of processes within the Darwin LNG as it transitions to the Barossa gas fields. Incite Energy was asked to provide a feasibility study for the provision of over-the-fence renewable electricity.
Incite Energy provided optimised renewable energy solutions for a range of scenarios, all of which included the needed network infrastructure to connect DLNG to the Darwin-Katherine Power System and renewable energy providers. Reliable electricity supply solutions included consideration for existing and new gas-fired generation, solar power and Battery Energy Storage System (BESS). Network solutions were designed to manage uninterrupted electricity supply during a staged investment program, and the anticipated addition of neighbouring loads. Scenario analysis was used to consider different gas prices, carbon emission prices and renewable energy certificate values.
Modelling was undertaken using Helioscope to determine solar generation output over a 25-year investment horizon, with HOMER Pro used to determine the Lowest Cost of Electricity (LCOE).
