Australia's electricity system will need up to $1 trillion of investment by 2050, regardless of whether consumers are providing their own energy or buying it from the grid, according to a new industry report.

The Energy Networks Association (ENA) is working with the CSIRO to develop a 10-year roadmap for the industry, to help it cope with a rapidly changing market.
"We're expecting to see a lot more of the decision-making being done by customers, and customers deciding what technology they'll install," the association's chief executive John Bradley told AM.

The CSIRO has modelled four different scenarios for Australia's energy market: one where consumers "set and forget" their energy use, the rise of the "prosumer" who is actively involved in sourcing their energy, another where people leave the grid altogether, and finally a market of 100 per cent renewables.
