This paper explores the technical and economic opportunities and issues that exist to provide demand response to the electricity grid from an aggregated network of electric vehicle supply equipment. Using data from the roll out of a large scale electric vehicle charging network in the U.S., and a review of information on the current demand response programs on offer in the U.S., issues such as the recruitment of electric vehicle charging units and users, the required control and communication capabilities of electric vehicle supply equipment and back-office network, and an example of the associated revenue potential are discussed. Finally, a number of recommendations for an aggregated network of electric vehicle supply equipment to provide demand response to the electricity grid are presented.
