Australia's Most Powerful Battery Storage Project Reaches Full Operation, Boosting Renewable Energy Integration

Published: Sep 28, 2026 15:35 (GMT+8)
[Australia's Largest Battery Energy Storage Project Running at Full Capacity] Australia's most powerful battery energy storage project has begun operating at full capacity, adding critical fast-response capability to the power system as aging coal-fired plants are retired and renewable energy generation expands. The New South Wales government said on Monday that the Australian Energy Market Operator has approved the Waratah Super Battery in the state for full operation. The battery has an energy storage capacity of 1,680 megawatt hours and has been in partial operation since August 2025. State Energy Minister Penny Sharpe said in a statement: "As aging coal-fired power plants retire, this project will help ensure electricity supply for households and enterprises while allowing more renewable energy to flow into the grid."

Nickel 28 Reports 811 Tonnes of Cobalt Production and 881 Tonnes of Sales at Ramu in Q2
According to Nickel 28 on September 21, the Ramu nickel-cobalt integrated operation in Papua New Guinea, in which the company holds an 8.56% joint-venture interest, produced 811 tonnes of contained cobalt in MHP during the second quarter of 2026 and sold 881 tonnes. During the same period, contained nickel production reached 8,234 tonnes, while sales totaled 8,967 tonnes. Nickel 28 said Ramu maintained solid operating performance during the quarter. Higher sulphur prices increased operating costs, but this was partly offset by relatively strong nickel and cobalt prices, solid production and sales volumes, and favorable payability levels. The company expects second-half production and sales to remain broadly in line with the first half, while nickel and cobalt prices, payability levels and sulphur costs will remain key factors affecting profitability.
