Energy Storage

The Australian Renewable Energy Agency has announced a $100 million competitive funding round for grid scale batteries. While battery technology agnostic, the projects must be equipped with advanced inverter technology.

Neoen today announced construction has begun on its 100 MW/200 MWh Capital Battery, which doubled from its initial 50 MW capacity proposed last year. The battery is to be built 10km southeast of the Australian capital, Canberra.

Hitachi Energy has won Northern Territory Labor’s tender for the Darwin-Katherine ‘Big Battery’, which is expected to unlock more capacity for residential and industrial PV, generate cost savings of $9.8 million and pay for itself in approximately five years.

The impression of another big battery being installed on the site of one of Australia’s recently decommissioned “coal clunkers” was lost on few. Battery system provider Fluence says the Hazelwood Battery Energy Storage System’s business case was bolstered by recent reforms and new technology to take advantage of rapidly changing wholesale electricity market dynamics.

The 300 MW / 450 MWh Victorian big battery in Geelong has today commenced operation. In spite of fire breaking out during commissioning in July, the battery has been delivered in record time, taking less than a year to build and begin operations.

Batteries in South Australia have been paid to charge throughout September and October 2021 due to a record number of negative price intervals. Wholesale electricity prices were negative almost 40% of the time.

The Australian Energy Market Commission has opted not to move “the goal posts on network charges” for energy storage projects, including large-scale batteries and pumped hydro, rejecting a request from the Australian Electricity Market Operator to exempt operators from being charged when drawing power.

Scientists in the United States pieced together data from hundreds of different sources, looking to establish the key factors that have led to consistently falling prices for lithium-ion technology since their commercialisation thirty years ago. They find that public-funded research, primarily in chemistry and materials science, has made the largest contribution to cost reduction. And they offer suggestions on policy and investment to ensure that the research can continue to make these important contributions to reduction in battery costs.

BloombergNEF says falling battery costs and “surging” renewables penetration make energy storage a “compelling flexible resource in many power systems.” Australia is among the predicted top markets.

Less than a year ago and energy market analysts Cornwall Insight Australia projected a battery energy storage pipeline of 7 GW. This week the firm has updated its outlook and puts Australia’s current pipeline of proposed projects at over 26 GW. What is more, the technical lifetime of these assets is increasing too.
