January 29, 2019 | Vehicle-to-grid (V2G) integration is not a new idea. What if all these mobile batteries could help balance power supplies? Bi-directional flow of electrons and communication between grid and vehicle offers a solution to the very problem EVs create, the World Economic Forum argues. It helps balance the load curve of the intermittent generation of renewables, on the supply side, with peak demand from increasingly electrified households. Commercializing V2G will deepen the convergence of the transport and utility sectors. In its purest form, grid operators will be rewarded with a more reliable system and a reduced cost to operate.
