As the world shifts to renewable energy, the importance of battery storage becomes more and more evident with intermittent sources of generation – wind and solar – playing an increasing role during the transition. Storage of electricity is an important part of achieving electricity independence and reducing your reliability on the grid. Electricity stored in a battery is often the easy part, with true value coming from the management o fhow and when the battery charges and discharges.

The Need for Battery Energy System Storage (BESS)

  • Balancing Renewable Energy: .Battery storage systems can store excess energy generated during peak production periods and release it when demand is high or renewable generation is low, ensuring a stable and reliable power supply.
  • Grid Stability: Battery storage can help stabilise the grid by providing fast response times to fluctuations in energy demand and supply. This is particularly crucial as more renewable energy is integrated into the grid.
  • Reducing Reliance on Fossil Fuels: By storing renewable energy, battery storage can help reduce the reliance on fossil fuels and lower greenhouse gas emissions, contributing to a more sustainable future.

Australia's Battery Storage Initiatives

  • Large-Scale Battery Projects:
    • Several large-scale battery projects are under development across the country, including The Hornsdale Power Reserve - the world's largest lithium-ion battery in South Australia. It provides essential grid-support services.
    • The first 100 MW/129 MWh was completed in November 2017. In its first two years of operation the Hornsdale Power Reserve confirmed the benefits associated with grid-scale batteries in the National Electricity Market and saved South Australian consumers over $150 million.
  • Residential Battery Systems: A residential energy storage system allows homeowners to accumulate electrical energy generated from renewable sources or purchased from the grid at off-peak rates. This stored energy can be discharged to provide backup power during grid outages, reduce reliance on the grid, and minimize energy costs by utilising stored energy during peak demand periods, when electricity rates are typically higher.
  • Government Support: Australia has set renewable energy targets, aiming to achieve 50% renewable electricity by 2030. To support this goal, the government has implemented the Large-Scale Renewable Energy Target (LRET) and the Small-Scale Renewable Energy Scheme (SRES). These policies create incentives for the deployment of renewable energy and storage projects, driving investment and innovation in the sector.

Current Climate and Outlook

Australia's battery storage industry is poised for substantial growth and innovation. With increasing renewable energy penetration, the demand for reliable energy storage is escalating. By 2030, the nation's installed battery storage capacity could reach 30 GWh. Advancements in battery chemistry, materials, and manufacturing processes are reducing costs and enhancing performance. These innovations, coupled with increased energy density and longer battery life, are making battery storage more accessible and cost- effective. This growth will drive economic development,create jobs, and foster local supply chains. Moreover, the integration o fbattery storage with renewable energy sources will play a pivotal role in Australia's transition to a low-carbon future. By mitigating the intermittency of renewable energy, batteries will ensure a stable and reliable electricity supply. Australia's abundant renewable resources, strong research capabilities,and supportive policy environment position the country to lead the global battery storage market and shape a sustainable energy future.

BESS and Embedded Networks

While much of the focus on BESS is on utility scale and individual homes as described above, the opportunity for their involvement in Embedded Networks is just as attractive. Solar and battery storage can significantly reduce the volume of energy purchased at the main connection point of an Embedded Network, without reducing the volume of energy tenants are recording at their sub-meter. This interaction between the reduced volume of electricity purchased from the grid, and the volume of electricity sold to tenants can generate attractive profits. These profits are often used to provide strong return on investment (ROI) but can also be used to discount the cost of electricity for the customers within the embedded network.

What was previously envisioned as a solution only for Microgrids,’ is now readily available for the right Embedded Network environment.

Most recently, more embedded networks are also integrating BESS technology to take advantage of market energy rates. Discharging in peak times to the market, purchasing at off-peak times or engaging in Ancillary Services to benefit from additional income streams. The innovation in opportunities available to Embedded Network Owners and Operators through these BESS arrangements, will be a fantastic area of the market to be involved in and watch evolve over the coming years.

Conclusion

Battery storage is a critical component of Australia's transition to a clean energy future. By enabling the efficient storage and utilization of renewable energy, battery storage can help ensure a reliable,sustainable, and affordable power supply for the nation.
