Powin和BlackRock已着手合作开发一款电池，并声称这是世界上最强大的电池。目前，BlackRock旗下公司Akaysha Energy正在悉尼以北开发1.9 GWh的瓦拉塔超级电池项目。
该公司已签订电池交付合同，并保证电池的持续功率容量至少为700 MW、可用储能容量至少为1400 MWh。Powin日前宣布这款电池将提供909 MW的电力设备容量和1915 MWh的年储能容量。
Powin将提供2592套Centipede模块化电池储能（BESS）平台，其子公司EKS Energy将提供288套功率转换系统。该项目预计将从2023年开始建设，目标完工时间为2025年中期。其中，BESS系统预计将作为系统完整性保护计划（SIPS）的一部分，充当澳大利亚电网的“减震器”。
Powin发表声明称：“这个SIPS关键项目将释放现有输电系统中的输电容量潜力，帮助整合可再生能源，并在发生雷击或山火等导致电力故障时充当‘减震器’而保持电网的可靠性。拟议的WSB项目将确保悉尼、纽卡斯尔和卧龙岗能够从现有发电机获得更多能源，同时降低电力中断的风险。”
Akaysha Energy在10月份的招标中赢得该储能项目，并将在1400 MW的Munmorah燃煤发电厂旧址建设这个项目。
