- A simple alert from the app if your usage is high during the peak period "Hey it looks like you might have your car charging! You can charge overnight for a fraction of the price."
I think this would be a great addition whether or not you have a car charger. Either automated based on average usage or a manually set level in the app, a "You seem to be using a lot more energy than usual at this time, could you save money by switching things on overnight instead?" as a push notification could be nice.
Push notifications for when cheaper tariffs are happening could be a nice option to turn on and off too:
“Notify me when my peak rate begins”
“Notify me when my standard rate begins”
“Notify me when my off-peak rate begins”
Of course one of the biggest barriers to EV adoption is education. Perhaps Bulb could mention somewhere the annual fuel cost of a car vs charging overnight for the average driver?
The average driver (apparently) does 8,000 miles a year.
The average petrol car gets 52.2 mpg (under the old rating system, this is likely actually far lower). Which gives us 153 gallons of petrol per year, or about 695 litres which costs £914 a year at today's price. Just over 1 1/2 tons of CO2!
Say an EV gets 4 miles / kWh… so for 8,000 miles we need 2 MWh (2,000 kWh). If you charge exclusively overnight on Bulb’s smart tariff that’s £151.80 a year, increasing your electric bill by £12.65 a month. A saving of over £63 a month. I’d also provide an example for high mileage drivers.
For me, the biggest issue is on-street parking/charging and availability of vehicles. I don’t have a dedicated space in front of my house (although I can generally get a space as a few houses don’t have cars), so I couldn’t reliably charge from my house, and as a tradesman I don’t have much of an opportunity to go and sit at a charging station for half an hour waiting for a top-up. Half an hour a day or so a week quickly removes any cost advantages of going electric over fossil.
Until the Transit Custom PHEV/electric comes out, there’s also not really a suitable vehicle out there for me to consider.
