佛蒙特州通过绿山电力公司推行的家庭电池租赁项目已形成虚拟电厂，成为该州最大的电力来源。1超过5500户家庭安装了电池系统，这些分散部署的家庭电池聚合而成的虚拟电厂现已提供110MW电力，相当于一座小型天然气发电厂的规模。1
该项目为客户提供租赁服务，月费为55美元、10年承诺期。1去年虚拟电厂为参与客户节省了1100万美元。1绿山电力公司以此替代了传统燃油尖峰电厂，同时帮助居民应对频繁停电，目标是到2030年消除所有停电情况。1约50%装有家庭电池的参与户还安装了屋顶太阳能。1
从全美范围看，虚拟电厂容量已超过40GW，预计到2030年将增长至160GW。1美国能源部预测虚拟电厂技术到2030年可为全国节省超过100亿美元。1
Green Mountain Power, Vermont's major utility company, has deployed a distributed battery storage program that has fundamentally reshaped the state's energy infrastructure. More than 5,500 households now participate in the home battery rental initiative, with monthly fees of $55 under 10-year agreements 1. These individual residential batteries aggregate into a virtual power plant that has become Vermont's largest electricity source, collectively supplying 110 megawatts of power—equivalent to a small natural gas plant 1.
The virtual power plant has demonstrated significant economic and operational benefits for participants and the grid alike. Last year, the program saved customers a combined $11 million 1, while enabling Green Mountain Power to eliminate traditional fuel oil peaking plants that previously met demand during peak hours 1. Approximately half of the households with installed home batteries have also invested in rooftop solar systems 1. The company has set an ambitious goal to eliminate all power outages by 2030 1.
The Vermont program exemplifies a broader national trend toward distributed energy resources. Virtual power plants across the United States now exceed 40 gigawatts in capacity, with the U.S. Department of Energy projecting they will reach 160 gigawatts by 2030 1. That expansion is expected to deliver savings exceeding $10 billion to American consumers by 2030 1.
