Grids & Integration

As it transitions from a wind-dominated renewable energy mix to include a wider range of energy options such as large-scale PV, pumped hydro and battery storage projects, South Australia is considering new planning policies.

Study claims that investment in a new 1GW nuclear power plant leads to average losses of approximately 4.8 billion euros. It further argues that the technology’s dangerous radioactivity emissions and proliferation risks do not qualify it as a ‘clean’ energy solution to be considered for addressing climate change. Yet still, governments are incorporating the technology into clean energy plans around the world.

With the approval for a 176 MW solar farm and 66 MW battery storage facility near Murray Bridge, South Australia’s utility-scale wind and solar pipeline has reached some 10 GW.

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.

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.

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.

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.

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.

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.
