Analysis says South Australia is setting an example for renewable energy transition

first_img FacebookTwitterLinkedInEmailPrint分享Renew Economy:South Australia – now generating more than 50 per cent of its electricity needs from wind and solar – is an example to the rest of Australia, and the world, on how grids can move beyond “baseload” and transition to low emissions grid dominated by renewables.Or, to put it another way, South Australia’s grid provides real world evidence of how a new base load generator, such as the nuclear power station some in the Coalition are so keen on building, would now be impossible to incorporate into a system with high levels of variable renewable generation.That is the key message from the latest National Energy Emissions Audit from The Australia Institute: South Australia is past the point of return to new baseload generation, and the world – and the federal government of Australia – should take note. The report, authored by Hugh Saddler, notes that for nine of the last 18 months, half of all electricity supplied in S.A. has been from renewable generators, including rooftop solar.This renewable generation has at times been enough to meet all of the state’s energy demand and – as AEMO has acknowledged – will be able to gradually reduce market interventions such as directing gas generators to run as more synchronous condensers come on line.“South Australia is showing Australia and the rest of the world how best to integrate new generation on a large scale,” says Saddler. “The inter-connector between South Australia and Victoria was completed more than 30 years ago, and since then South Australia has almost always been a net importer of electricity from Victoria. Now, thanks to its strong renewables leadership and uptake, it is a net exporter of electricity to Victoria for most months of the year.”“Eliminating ‘base load’ is what the transition to a low emission renewable generation based electricity supply system is doing,” the report says; “in South Australia, in the rest of Australia, and round the world. The complement to variable renewable generation is not so-called “base load” generation (a meaningless term), but energy storage in some of its many forms and spatial/climatic diversification of renewable generation.”More: South Australia “an example to the world” of how to move beyond baseload Analysis says South Australia is setting an example for renewable energy transitionlast_img read more
