  3. Purpose of the study • Part of the Government’s Clean Energy Future Plan • The Australian Energy Market Operator (AEMO) tasked with expanding its planning scenarios • … to prepare for greater use of renewable energy

  4. Scope of the study The modelling will investigate: • scenarios for a 100 per cent renewable electricity supply at 2030 and 2050; • generation plant and major transmission networks required to support each scenario; • the estimated capital cost requirements; and • an estimate of the impact on customer energy prices.

  5. Broader context National Electricity Market • Over $10 billion of electricity traded annually • Network asset values >$55bnwith investment of ~$8bn annually • Major undertaking to consider a 100% Renewables mix • This is the first step Source: AEMO 2010
