Nissan, E.ON Drive and Imperial College London have published a whitepaper exploring the benefits of bi-directional charging electric vehicles (EVs).
The whitepaper suggests that fleets using vehicle-to-grid (V2G) charging could could expect to cut electricity operating costs by up to £12,000 per annum per EV and reduce CO2 by approximately 60 tonnes per annuam per EV.
Meanwhile, annual fleet V2G charging benefits could range between £700-£1,250 per vehicle, it says.
It estimates an overall power system cost saving of £410m-£885m per year during the next decade from offsetting capital and operational expenditure.
Andrew Humberstone, managing director of Nissan Motor GB, said: “There is enormous potential in vehicle-to-grid to deliver huge savings, both in financial terms for electricity system operators and vehicle fleets, and in environmental terms, by significantly cutting CO2 emissions across the UK power system. Nissan is at the forefront of efforts to realise this potential.”
