Vermont Utility testing battery storage system for power metering

Green Mountain Power, an energy provider to 265,000 consumers in the US state of Vermont, is testing the usage of battery energy storage to measure energy delivery whilst reducing consumer energy costs. As part of the Resilient Home pilot programme, the utility is partnering with Tesla to replace traditional energy meters with a battery energy storage system. The pilot is open to 250 consumers. The project is expected to provide consumers with increased resiliency during outages at the same time reducing their carbon footprint. Customers participating in the pilot can buy two Tesla Powerwall batteries for $30 a month or purchase the battery via the utility’s Bring Your Own Device initiative at discounted price. The batteries provide whole-home backup power, switching on seamlessly during outages like a generator. The battery system will also provide energy metering capabilities. The service will include customers choosing a convenient, flat monthly price for power, and lock it in for a year. Consumers can also generate excess revenue by selling their stored energy to the utility during times when demand on the main grid is high. The pilot falls under efforts by the utility to prepare its customers for future business models and to adopt new technologies such as solar and smart devices.
