Launching the inaugural National Transmission Network Development Plan, Resources, Energy Minister, Martin Ferguson, said that "we’ll need to invest between $40 and $130 billion in generation and transmission investments by 2030 to continue to meet the expectations of consumers."
The Transmission Plan, developed by the Australian Energy Market Operator, envisages that the bulk of new power generation over the next 20 years will be from gas although some new coal-fired power plants will be built. There will be significant retirement of of brown coal plant in the La Trobe Valley (to be replaced by gas) and retirement of Australia’s least efficient black coal power plants at Collinsville and Wallerawang.
The Australian Energy Market Operator has also released a Gas Statement of Opportunities and National Energy Scenarios Modelling.
