2017年，圣地亚哥天然气电力公司安装了一个30兆瓦、120兆瓦时的锂离子电池存储设施--当时世界上最大的。但是，最近的研究表明，就地控制可以使灵活的负载为电网提供同等的类似电池的服务。我们的成本比较表明，通过将12万台热水器改造成控制硬件和电信设备，获得30兆瓦、120兆瓦时的容量要便宜得多。令人惊讶的是，赠送12万台智能热水器可能还会更便宜！
In 2017, San Diego Gas & Electric installed a 30 MW, 120 MWh lithium-ion battery storage facility–the world’s largest at the time. But, recent work demonstrates that local control can enable flexible loads to provide equivalent battery-like services to the grid. Our cost comparison shows that it is much cheaper to acquire 30 MW, 120 MWh of capacity by retro-fitting 120,000 water heaters with control hardware and telecommunications. Surprisingly, it may even be cheaper to give away 120,000 ‘smart’ water heaters!
