GMP Saves Money for Customers with V2G
December 2020 - Pioneering work by GMP is expanding the possibilities of stored energy for customers – and saving them money! GMP is the first utility to use stored energy from an electric vehicle’s battery to help reduce peak demand on the grid. Reducing energy use during peaks saves GMP customers money, because peaks are when energy can be most expensive and carbon intensive.
How did we do it? With something called V2G technology. V2G is vehicle-to-grid energy flow – back and forth from a vehicle to the grid – and it’s done with an innovative electric vehicle charger. In October, GMP used a Fermata Energy bi-directional charger operated by Fermata’s V2G software system at GMP’s Colchester office and started using it to charge one of our fleet vehicles – an all-electric Nissan LEAF. Employees use the car to get around during the day. And now, GMP is also using stored energy in the Nissan’s battery to help reduce peak energy use. It is the first time this has been done in ‘real-world’ conditions – and the car still has plenty of power to drive!
