‘Better bang for buck': NSW to cut battery subsidies as federal scheme kicks in
Since last November, NSW consumers have been able to access a rebate of up to $2600 (depending on the size of the battery) to attach storage to their rooftop solar systems. The scheme resulted in 11,400 battery installations across the state in six months.
The program will conclude at the end of this month, while the Australian government's $2.3 billion Cheaper Home Batteries Program is set to start on July 1. The federal rebate, announced before the election, will reduce the cost of a battery by about 30 per cent, making it about double the size of the state scheme.
The NSW government will redirect the money to its Peak Demand Reduction Scheme, a program designed to reduce electricity demand during peak periods. In particular, the government is doubling the payments to encourage solar households to sign up to a virtual power plant (VPP) – a group of solar-powered batteries linked by software, which are owned by households and small businesses that have consented for excess stored power to be sold to the grid.
Smart Energy Council acting chief executive Wayne Smith said VPPs were important because it increased the stability of the grid and this lowered power bills for everyone, not just those households with solar panels and batteries.
'There's a private benefit and a public good,' Smith said. 'It's actually important to find ways to try to integrate the individual home batteries into a much bigger collective battery system.'
The Smart Energy Council says a 6 kWh battery at $6000-$8000 would meet the needs of nine out of 10 homes. The federal subsidy would be about $2232 and the NSW incentive to connect to a VPP would be about $444.
On an 11.5kWh battery, the federal subsidy would be about $4278 and the NSW support for a VPP connection would be $850.

The PM talked up green steel. But is it even a thing?
Champions of a green steel industry, such as the economist Ross Garnaut, a director of The Superpower Institute and the clean power company ZEN Energy, along with Andrew Forrest of Fortescue Metals Group, argue that Australia is uniquely placed to lead this potential new industry: we have the world's largest iron ore reserves and the vast space for the wind and solar farms needed to power the industry. Is it happening yet? Not at large scale. A Swedish consortium, Hybrit, has made around 5000 tonnes of hydrogen-reduced iron, and advances are being made in Australia. ZEN Energy is working with European and Asian partners to develop a green iron project to supply a new electric arc furnace at Wyalla in South Australia, while Fortescue has a green metal project underway at Christmas Creek in the Pilbara. What's the hold up? Cost and complexity. The industrial supply chain to produce green steel is long, complicated and expensive. It demands that a hydrogen industry be built to sustain it, and cost-effective ways of storing that hydrogen, and massive amounts of green energy, which also must be stored. The cost of each those processes must also be driven down. While renewable energy costs are tumbling, hydrogen remains comparatively expensive. Back when hydrogen cost around $15 a kilo former Prime Minister Scott Morrison announced an energy policy designed to drive it down to $2 per kilo. Today it remains closer to $10. 'It means a lot of large organisations making big expensive bets, and getting enough of them right,' explains Tony Wood, senior fellow with the Grattan Institute's energy program. 'The question is, who is going to cover the risk?' Finally, the product they make will be more expensive than conventional steel, which means the industry will need customers willing to pay a premium for a clean product. If countries are to meet their Paris Agreement targets, it is expected that market will grow. Garnaut believes the industry needs the support of a carbon price. Are there advantages beyond greenhouse gas emissions? Absolutely. As Albanese said on Monday, Australia is already the world's largest exporter of iron ore. If we can scale green iron at a viable cost we can add value to the product. 'The value of the green iron would be two or three times the value of the iron ore,' says Garnaut, pointing to a Superpower Institute paper that found if green iron replaced iron ore as a primary export, it could generate up to $386 billion annually by 2060. By comparison, Australia's iron ore exports are typically around $120 billion per year. This would provide a strategic hedge against the expected decline in coal exports. With a large scale green iron or steel industry, Australia could not only help decarbonise its own economy, but that of its iron customers, who would be purchasing Australian green energy embodied in the iron products. This would be far more efficient than exporting Australian hydrogen and iron ore to be produced offshore into iron and steel, and it could reduce global emissions by four per cent, Garnaut argues.

Key decision to decide Australia's future
Australia's over reliance on unexpected high iron ore prices to fix the national budget could be coming to an end, with a key choice from China to decide Australia's future. The Prime Minister held a roundtable on Monday with key local mining figures and Chinese steelmakers to spruik the benefit of buying Australian iron ore. Much of Australia's wealth is made off the back of the mining sector, as Australia pockets around $105bn in return for supplying China with around two-thirds of its iron ore needs. In 2024, Australia sold more than $150bn of iron ore around the world. But this relationship is coming under threat as China's huge steel manufacturing sector looks to decarbonise, meaning they could need the higher quality iron ore found in the likes of Brazil and Guinea. AMP chief economist Shane Oliver told NewsWire how damaging any changes to iron exports would be to the national economy depends on the pace of change. Anthony Albanese and Australian businessman Andrew 'Twiggy' Forrest met with officials to discuss Australia's iron ore sector. NewsWire / Joseph Olbrycht-Palmer Credit: NewsWire 'My take on that is if it occurs gradually over time, then Australia would adjust,' he said. 'If it occurs very quickly in a short space of time then it'd be a big problem.' 'It comes to the broader issue that about 35 per cent of our exports go to China,' Dr Oliver said. Dr Oliver flagged it could be any number of reasons which could impact Australia's iron ore miners, listing supply from other sources, a hit to the Chinese economy, geopolitical issues with the US as potential reasons for slowing this trade. He said while there was fresh interest in the issue in the context of other tensions between the two countries, the problem was nothing Australia hadn't endured before. 'I can understand why people love to talk about it, but it's been around for the last couple of decades and it is an issue,' he said. Australia can take steps to diversify away from iron ore. NewsWire / Nicholas Eagar Credit: NewsWire 'By the same token in a market economy like Australia, the decision of where our exports go is basically, I'd say 90 per cent driven by free markets and companies operating within that.' Despite the looming risks, Australia could remain 'the lucky country' based on two potential replacements to the country's large iron ore intake. 'We had been moving towards services exports, particularly education,' Dr Oliver said. 'That is why we have to be careful here that Australia doesn't shoot itself in the foot by restricting immigration that turns off the education export sector that is a potential replacement. 'I suspect if things had continued as they were we would have found a situation where in the next few years, education would've been our second highest export, ahead of gas and coal and just behind iron ore.' However, Australia is already struggling with a housing crisis and both major parties used the recent election to point to international students as a key reason why rents are skyrocketing. Previous research from the Property Council of Australia suggests just 4 per cent of rentals were taken up by international students, while a further 6 per cent was taken up by domestic students. The other aspect is a boost to the lithium and rare earths sector which is tipped to boom in future years. 'You want to make it easier for companies to develop new industries, with rare earths for example being a potential hedge [to iron ore],' he said, noting Australia had plentiful reserves.
