The Hornsdale Power Reserve in South Australia, aka the “Tesla big battery”, has finally won approval to become the world’s first large battery to provide grid-scale inertial service. The approval comes from the Australian Energy Market Operator after nearly two years of trial and error, and is considered another important step towards managing the electricity grid with 100 per cent renewable energy and no coal and gas generators in operation. The Hornsdale battery, which is owned by Neoen and expanded to 150MW/193MWh in 2020 to help provide this additional service, will be the first of many such batteries to operate on what is known as an “advanced” or “grid-shaping” inverter. This inverter is capable of providing many of the critical network services normally provided by thermal power, but requires detailed testing to help manage the transition from large spinning machines to precise digital technology. The Hornsdale battery uses Tesla’s “virtual machine mode” technology, and this

How many storages have high grating – 90 percent or more – varying wind and solar requirements to ensure there is enough supply to meet demand? This is a hot topic inside and outside the energy circle. One common theory – often pushed by the nuclear and fossil fuel lobbies, and the former Coalition government – ​​is that you should match each kW of wind and solar capacity to an equivalent amount of storage. The CSIRO says the idea is wrong, and Australia will only need to install a fraction of the storage for every kW of renewable energy – between one-fifth and one-third – to meet demand. “Such a conclusion would substantially overestimate the need for storage capacity,” said CSIRO in an updated version of the GenCost report, a landmark annual document that tracks the costs of comparable energy technologies, and in the case of wind and solar, their storage and transmission. needs too. The reason for this, says CSIRO, is that although the generation mix is ​​changed, and significantly

The Australian Renewable Energy Agency has received an overwhelming response to its offer of a $100 million grant for an ‘advanced’ grid-scale battery project, which is seen as critical to the transition to a 100 percent renewable energy grid. A shortlist of 12 projects representing capacity in excess of 3GW and 7GWh storage was completed from more than 54 proposals. ARENA said its response “far exceeded expectations,” and underlined the major development path of Australia’s large battery storage project. Funding will be provided for at least three projects and selected projects have been asked to submit full applications for their share of the funding offer, available for new and existing projects equipped with ‘advanced’ inverters. Selected projects totaled a combined $297 million of grant requests, for a total investment value of $3.7 billion. The figures suggest that ARENA’s funding could eventually support the development of approximately 1,000 MW of new battery storage capacit
