![]() ![]() The idea underlying the EU legislation is that the EVs will act as storage batteries that can be charged from the grid during periods of low demand and/or high generation and discharged back into the grid during periods of high demand and/or low generation, thereby smoothing out the load curve while making full use of intermittent renewables generation. EV purchase costs (which would probably have to be subsidized) needed to distribute the additional electricity and charge/discharge the EVs.ħ. The grid upgrades, domestic wiring upgrades, charging stations, smart meters etc. I could, however, make no estimates for the following items, which could – almost certainly will – significantly increase costs:Ħ. ![]() Average cost of additional capacity in $/kW installedĪfter once more checking a number of capital cost estimates I estimated an overall cost of $3,000 per installed kilowatt. After checking various published numbers I estimated an overall capacity factor of 30%.ĥ. The idea of going to EVs is to reduce GHG emissions, so I assumed that the additional capacity would be “new renewables” – dominantly offshore wind and solar PV. Average capacity factor of the additional electric capacity needed. I used the median value of 22kWh (equivalent to 153 miles per US gallon according to the US EPA) obtained from 114 test values published by the US DOE.Ĥ. Average distance driven per vehicle per year. In some cases the numbers are not entirely reliable.Ģ. I obtained these data from a variety of sources too numerous to cite. Number of cars and light vehicles currently registered I used the following data to make estimates of how much additional electricity and electric generating capacity would be needed to power the EV fleets:ġ. Because of the uncertainties in the data and assumptions used the numbers should be considered as ball-park estimates only. None of this legislation has as yet been approved, but if it is how much extra electricity will be needed to power the millions of EVs involved, and how much will it cost? I’ve seen no numbers on this, so in this post I present some, starting with Germany, the Netherlands and the EU and adding a few more countries – and the world – as we go. As reported in Blowout week 146 the EU is drafting legislation to mandate the installation of electric vehicle charging stations in new homes while Germany and the Netherlands are considering legislation requiring that all cars and light vehicles sold after 2025 or 2030 must be 100% electric.
