Work has begun on a new megawatt battery in the South West which hopes to stabilise fluctuations in energy production from the region’s power grid. Construction of the 100 megawatt battery got under way at Wagerup Power Station in the Shire of Waroona last Wednesday which is set to be larger than a normal household battery upon completion. Electricity generator and gas provider Alinta Energy has contracted Shanghai Electric Power Design Institute and Sunterra to deliver the project. WA executive director Chris Campbell said the company hoped to make a substantial contribution to the transition of the South West Interconnected System. “We feel very privileged to be among the first wave of developments and continuing to invest in in the State,” he said. Mr Campbell said the company could see both the challenge and opportunity in the energy transition. “We certainly look forward to investing further in that transition that requires innovative thinking, speed and collaboration,” he said. Energy Minister Bill Johnston noted there were a number of challenges in managing the system with fluctuating renewable energy production. “Having batteries is an important contributor to ... giving you more flexibility in the network to take account of variable renewable output,” he said. Mr Johnston said he hoped there would continue to be opportunities for private sector investment in the State’s main power grid. Representatives from the Shire of Waroona, Alcoa, Western Power and Murray-Wellington MLA Robyn Clarke were among those who attended the sod-turning ceremony on Wednesday, with the promising new battery expected to be completed late next year.
