Description
Summary:► In 2008, the Irish government set a target that 10% of all vehicles be powered by electricity by 2020. ► The impact of EV charging in the single wholesale electricity market in Ireland is analysed. ► EV charging under peak and off-peak charging scenarios is examined. ► Results show that off-peak charging is more beneficial than peak charging. ► Only 1.55% of the Non-ETS and 1.45% of the RES-T targets are achieved. The Irish government set a target in 2008 that 10% of all vehicles in the transport fleet be powered by electricity by 2020. Similar electric vehicle targets have been introduced in other countries. In this study the effects of 213,561 electric vehicles on the operation of the single wholesale electricity market for the Republic of Ireland and Northern Ireland is investigated. A model of Ireland’s electricity market in 2020 is developed using the power systems market model called PLEXOS for power systems. The amount of CO2 emissions associated with charging the EVs and the impacts with respect to Ireland’s target for renewable energy in transport is also quantified. A single generation portfolio and two different charging scenarios, arising from a peak and off-peak charging profile are considered. Results from the study confirm that off-peak charging is more beneficial than peak charging and that charging EVs will contribute 1.45% energy supply to the 10% renewable energy in transport target. The net CO2 reductions are 147 and 210 kt CO2 respectively.
