Australia-Singapore power link, world’s biggest solar+storage project get government backing

The Northern Territory has given major project status to an ambitious plan to develop a 10 GW solar farm coupled with a 20-30 GWh storage facility near Tennant Creek and export solar power harvested in the Australian desert to Singapore via subsea cables.

Western Victoria’s network upgrade to unlock up to 6 GW of new wind and solar farms

The Australian Energy Market Operator (AEMO) has laid out a $370 million plan for network upgrades in Western Victoria which would deliver almost double the benefit to both energy consumers and energy producers. However, the proposal has provoked federal Energy Minister Angus Taylor’s attack on the state’s renewable energy target.

Green hydrogen joins natural gas in WA pipelines

Canadian gas giant ATCO has unveiled its Clean Energy Hub in Jandakot which will explore the potential of hydrogen for home use in gas appliances. On the same day, the Western Australian government has launched a renewable hydrogen strategy and announced the creation of a $10 million green hydrogen fund.

Australia’s first compressed air energy storage facility gets go-ahead

The South Australian government has given its tick of approval for the development of a 5 MW/10 MWh compressed air energy storage facility, which will store excess solar and wind power at a closed underground mine.

Wind and solar cut rather than boost Australia’s wholesale electricity prices

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.

Batteries well-suited to play valuable role in grid management in New Zealand’s energy transition

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.

Horizon Power’s Carnarvon DER trials picks up award

Western Australia utility Horizon Power’s Carnarvon Distributed Energy Resource (DER) PV trails have received the silver award in the Energy Smart Communities Initiatives (ESCI) Best Practice Awards in the category of Smart Grids. The award recognises the necessity of DER trailing in order to find better ways to integrate solar PV into regional locations. 

China auction allocates subsidies for 22.7 GW of solar with lowest bid of $0.0407/kWh

China’s National Energy Administration has given the greenlight to 3,921 ground-mounted and distributed generation projects. The approved energy price bids ranged from $0.0407 to $0.080, depending on system size, for an average price of $0.048.

Smart meter time of use pricing to drive up household energy costs without the help of solar and batteries

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.

Planet Ark Power smooths the way for urban solar farms

Voltage regulation creates challenges for grid operation, particularly at high penetration levels of solar and other distributed renewables. Fresh being recognised as energy transition pioneers at the recent Startup Energy Transition (SET) Awards in Berlin, Planet Ark Power and its behind-the-meter technology is looking to dynamize Australia’s, and the world’s, energy grids with distributed clean energy.
