Developments in Australian Energy System Modelling: an Energy Economics Perspective

Paul Graham

This presentation explores the key periods of cost increases in electricity generation in Australia and how CSIRO and the broader Australian modelling community responded to provide new modelling tools to explore the drivers of those cost increases and options for minimising costs in the future as the sector transitions to a higher renewables, greater customer-owned generation and lower emissions overall.

Paul Graham is Chief Economist at CSIRO’s Energy research unit and has been working in the field of energy economics for 30 years. His most high profile work is the GenCost project which provides annual updates and projections on the cost of generation, storage and hydrogen technologies. This is a key input to Australia’s electricity system planning. More broadly, he is responsible for providing advice on the economic drivers and outcomes for the energy sector as it meets new challenges and for leading projects of national significance in partnership with industry and government.
