CS Energy recently took an important step in our diversification into new energy sources with the construction of one of Queensland’s largest utility-scale batteries. The 400MWh Greenbank battery is part of an innovative partnership between Queensland’s publicly-owned CS Energy and Powerlink. The new battery follows the announcement of our Chinchilla Battery earlier this year and has the potential to be “a game-changer” in the way the grid is operated, capable of soaking up and storing the state’s solar and wind energy and feed into the system when Queenslanders need it. Queensland has one of the highest rates of rooftop solar installation in the world and large-scale batteries like Greenbank will allow us to capture this energy and help achieve Queensland’s 50 per cent renewable energy target by 2030. Investing in fast-start energy storage assets will give our portfolio greater flexibility to respond to changing demand patterns in the National Electricity Market. Batteries can rapidly respond when there is a sudden gap in electricity supply in the grid, which helps to reduce wholesale price volatility. Together, CS Energy and our partners aim to deliver more reliable, affordable and cleaner energy for Queensland. The Greenbank battery is one of 13 batteries to be rolled out by Queensland Government owned corporations.
