Grids & Integration

Researchers in the US have published a study that brings 20 years of renewable energy (solar PV and/or wind plus storage) generation into line with historical energy-demand profiles, to ascertain at what storage cost point renewables can cost-effectively consistently meet 100% demand.

The growing share of rooftop solar had a significant impact on Australia’s main grid in the latest quarter, both in terms of reducing operational demand and emissions intensity, the Australian Energy Market Operator (AEMO) said. Looking ahead, AEMO is seeking to procure off-market emergency reserves to help protect the grid from potential summer blackouts the upcoming summer, as coal generator outages grow in frequency.

French renewables developer Neoen has won development approval from the South Australian government for a major renewable energy project, comprising 125 MW of wind generation, 150 MW of solar PV generation and 130MW/400MWh of lithium-ion battery storage. The project could also integrate up to 50 MW of on-site hydrogen production capability.

The grant recipients for the fourth phase of the Next Generation Energy Storage program have been announced. Launched in 2016, the $25 million program is supporting the roll out of up to 36 MW of smart battery storage.

Energy companies are pushing back against a proposal to allow large energy consumers to enter the wholesale electricity market, as industry bodies point to the many benefits of the wholesale demand response program.

Western Australia’s government has announced two units at Synergy’s Muja Power Station will be retired from October 2022. The state government said the coal-fired units were only being used about 35% of the time thanks largely to rooftop solar reducing demand on the grid.

Australian renewables developer Windlab has connected and energized its landmark energy park in north Queensland, comprising 43 MW of wind, 18 MW of solar and a 4 MWh battery.

Wattwatchers provides consumers with real-time electricity data that allows them to tailor their electricity use to make best use of their rooftop solar power. Consumer rights to energy data is crucial to a successful future grid with high penetration of DER, says Wattwatchers’ MD Gavin Dietz.

The Australian utility-scale solar developer has reached the final development milestone on a solar and battery project near West Wyalong in the Riverina region.

With around 16 battery-based virtual-power-plant projects either in progress or planned across six states, Australia is demonstrating the potential of distributed energy resources to the world. An Australian Clean Energy Summit panel last week caught up on progress and potholes on the road to energy’s new two-way street.
