What modelling and assumptions, if any, underpins the estimate of a $2-$4/MWh levy on electricity to pay for the LNG facility?

Answer

These are broad figures drawn from a range of sources, including industry investigations into LNG and aggregated information from the procurement process. No specific details of the procurement process will be released at this stage. The range of levy costs are calculated as annual service fee divided by 2024 electricity generation.
