Energy Storage

Wholesale prices in the National Electricity Market have climbed significantly in recent years. The increase has coincided with a rapid increase in the proportion of electricity supplied by wind and solar generators. But that needn’t mean the increase in wind and solar generation caused the increase in prices. It might have been caused by other things.

A report published by New Zealand’s state-owned transmission grid operator Transpower finds the widespread uptake of distributed battery storage could play an important role in supporting the power system as rooftop PV and electric vehicles are increasingly adopted.

New research released this week by The Australia Institute shows that ‘time of use pricing’ (ToU) facilitated by smart meters is likely to drive up household energy costs by $429 a year on top of already high prices. Analysis of national electricity market data suggests that demand for electricity in Australia is very inelastic, which makes ToU more likely to increase the profits of electricity companies than to assist consumers. Households with solar PV and batteries, however, are best suited to cope with this type of pricing. 

Australia’s first large-scale project to use pumped hydro to store solar generated power, the Kidston facility in north Queensland, has landed a $610 million loan from the Federal Government’s the Northern Australia Infrastructure Facility (NAIF).

On the back of a combination of its industry-leading solar program and energy efficiencies, Vicinity Centers has announced a zero net carbon target by 2030 for its 34 shopping centers.

Under the right conditions, solar batteries are economically beneficial for South Australian homeowners and can pay for themselves off within the warranty period, a new research finds.

Increased storage and strategic transmission development will be needed to ensure the lowest cost and risk transition of Australia’s energy system, the Australian Energy Market Operator states in its latest study. In 20 years time, the need for storage will be at a scale not seen before in the NEM, and both pumped hydro storage and distributed storage are set to play major roles in lowering wholesale electricity prices and building a reliable and resilient power system.

Applications are now open for the Queensland government’s $15 million Hydrogen Industry Development Fund, which will support sustainable and renewable hydrogen projects across the state.

As one of the most energy-intensive industries, the resource sector is getting serious about integrating cheap wind and solar energy into its mix to boost bottom lines. Although still predominantly underpinned by gas or diesel, mine operations are increasingly deploying hybrid solutions pointing to the potential of the sector transitioning to 100% renewables – particularly as momentum builds for green hydrogen to play a role in future microgrids.

The first phase of a 6 MW solar array planned to power a former car manufacturing site at Tonsley in Adelaide will be delivered by ZEN Energy. The solar installation will ultimately work in conjunction with on-site battery storage and smart technologies as part of Enwave Australia’s Tonsley District Energy Scheme.
