While intermittent renewable power generation in the form of wind and solar PV has become a significant presence on the worlds electricity grids, the intermittency associated with this power supply introduces uncertainty into the grid operators task of matching supply with demand. A consequence of this intermittency is the large costs that accrue when supply is lower than forecasted and this cost is increasingly being laid at the feet of the power producers running intermittent generators. These uncertainties present a significant obstacle to renewable investment and future growth. In this paper we investigate the opportunities arising from the projected growth in electric vehicles (EV's) and vehicle-to-grid enabled charging infrastructure to hedge against the large price risk associated with spot markets by accessing the stored energy in the form of unused battery capacity in EV's. Specifically, we investigate the scale of an electric car fleet needed to effectively provide this service as opposed to the economics of correctly pricing the service. By employing Quality of Service (QoS) based metrics we show that the number of participating vehicles needed to mitigate production risk is small and the impact on these vehicles minimal.
