The chief energy economist with the CSIRO, Paul Graham, today launched the Electricity Network Transformation Roadmap: a strategy document that was a joint venture with utilities body Energy Networks Australia.

The roadmap sets out scenarios for the electricity generation sector until 2050 designed to achieve zero-net emissions systems. 

Mr Graham said the country's electricity system was experiencing change on an unprecedented scale and an estimated $100 billion in investment was needed to eventually achieve zero-net emissions. 

It is estimated that by 2050 millions of customer-owned generators will supply between 30 and 50 per cent of Australia's energy needs.

But Mr Graham warned that the inability of state and federal governments to nut out a coherent and stable energy policy threatens Australia's ability to reduce emissions.
