Grids & Integration

Another big battery has gone live in South Australia with the goal to contribute to energy security and reliability as a heatwave puts grid under pressure. The $30 million energy storage system is developed and owned by ElectraNet, as the first battery in the NEM to provide regulated network services and competitive market services.

At an energy storage fair in Dusseldorf, researchers will present a ceramic high-temperature battery. Storage costs using sodium-nickel-chloride battery cells are said to be 50% lower than those of lithium-ion.

The German car giant has created Elli, a subsidiary that will provide green power and charging solutions for the EV sector. Volkswagen – still haunted by the diesel emissions scandal – says it wants to make mobility sustainable.

The December meeting of the COAG Energy Council has grabbed headlines as NSW attempted to push for a zero-emissions policy only to be blocked by Federal Energy Minister Angus Taylor. But, in a rare substantive outcome of the meeting, the energy ministers agreed to develop a national hydrogen strategy.

The New South Wales government has launched its ambitious pumped hydro roadmap designed to back the rising level of wind and solar in the energy mix. Meanwhile, the board of government-owned energy provider Snowy Hydro has given the green light to its landmark $4 billion pumped hydro expansion project, Snowy 2.0.

Around 40 residential properties across the port city of Fremantle, Western Australia, will be able to trade solar power using a blockchain-enabled platform. The trial is even open for residents who do not have solar PV on their rooftops.

A new report analyzing the world’s largest lithium-ion battery’s performance in the first year of operation shows the Hornsdale Power Reserve has delivered on high expectations of its performance and market impact. It has helped stabilize the grid, avoid outages and reduce system costs, as well as triggered a surge in uptake of similar fast response systems across Australia.

The second phase of the proposed 250 MW virtual power plant will see Tesla Powerwall batteries and solar panels installed on 1,000 South Australian households.

As 2.1 GW of new capacity – mostly wind, solar and storage – has come online in the previous year, AEMO has sourced much less additional reserves than last year to manage potential high risk scenarios that typically occur in summer. Over the next two years, the market operator expects 6 GW of new wind and solar capacity to be connected to the grid, which will alleviate the short-term risk of involuntary load shedding during summer peak periods.

Australian developers Energy Estate and MirusWind have proposed a massive renewable energy hub in New South Wales. The project will combine wind and solar energy generation with pumped hydro storage and other storage options to provide up to 4 GW of new clean generation.
