![]() ![]() Now let's see what happens when we remove the 3.2 p/kWh green levies (while still leaving the other import levies in place). By exporting energy during peak times (and providing other high value services) V2G is able to provide significant system benefits over ‘smart’ charging, displacing the need for dirty fossil generation, providing back-up power for renewables and enabling more efficient usage of the network. What’s more, you can make more money by discharging energy from the vehicle back to the grid as soon as you get home - during ‘peak times’ - even if that means you’ve got to charge up more overnight (which can mean a slightly less efficient charge). Because the cost of importing electricity from the grid is so much higher at ‘peak times’ you can still save lots of money by delaying your charge until night time in the V2G scenario. We can compare the cost of charging in each of the scenarios outlined in the graph above. The console can now be purchased for 259.99, a reasonable 40 drop from the previous 299.99 price point its held onto for almost five years. The first thing to note is that typical household consumption is under 1kW during the evening (so whenever we are discharging the car a small portion goes to running the house, but most of this energy is exported back to the grid). ![]() These technologies are key to unlocking energy flexibility, which is vital for making renewables work on a large scale, and lowers energy costs for all consumers. Crucially, it would also provide a boost to green smart tech (namely bi-directional technologies like home batteries and Vehicle to Grid Charging). Taking green levies out of customers’ bills and including them in ‘general taxation’ would bring a wide range of benefits, while also helping with ‘rebalancing the costs placed on energy bills away from electricity users’ - a commitment laid out in the Government’s Energy Security Strategy. These subsidies have provided (and continue to provide) huge benefits for consumers by bringing forward lots of cheap wind and solar power, however there are different options for how we recover the costs. The money recovered from these levies is used to support subsidy schemes for renewable generators. Green Levies are charged on any energy consumed by homes and businesses and make up roughly £100 of the average person’s annual electricity bill. With energy costs going up, the energy crisis has brought new attention to all the smaller costs that make up your electricity bill, including green levies.
