Tesla has called on the Australian grid operator to change the nation’s 20-year grid blue-print to reflect rapid technology developments in battery storage, including the rapidly falling cost of the technology.

In a submission to the Australian Energy Market Operator about its Integrated System Plan, Tesla suggests modelling should reflect battery life of 15 years, rather than 10 years, a 90 per cent round trip efficiency, rather than 81 per cent, and cheaper costs.

The submission suggests battery storage will play a greater role in Australia’s future grid than has been suggested in scenarios focused on pumped hydro, Snowy 2.0 and Tasmania’s Battery of the Nation plan.

Tesla’s observations highlight the need to reflect rapid shift in technologies.The US-based company would like to see a “fast-change” scenario where both distributed energy resources (known as DER and which include rooftop solar, battery storage and demand management) and large-scale renewable storage uptake are maximised.
