Cheaper flat rates are terrible if you own an EV while alternatives like Go and Agile exist. If you don’t have an EV then a cheap flat rate is not as bad because it’s mainly about your base load as long as your peak isn’t too extreme. But as soon as you hit 7kW for several hours, the kWh rate *really* starts to matter. My base load is around 330W, so 7kW is 20x that. In other words, if I want to charge my car at 20x my base load but I can do that at a significantly cheaper rate (as long as I do it a certain time of day), even if the rest of the day the rate is higher, I’m still way better off. Agile is just a more dynamic version of Go. We’ve been paid money to charge our cars previously, and the last time I charged (a few days ago) it was at 2.5ish p/kWh.
Yesterday was one of the most expensive days on Agile I’ve seen, and still my average for the day was 14.96p/kWh (Go is 15p for 20h of the day). I’m extremely happy with Agile, but I’m a nerd and I enjoy “gaming” the system with data. Go gives you certainty to know those 4 hours every day are solid at 5p no matter what.
Here are my last 7 days, you can see I charged in the early hours of Sunday morning (and only around 10-12kWh) which massively brought down the average for the whole day to 5.38p. Your flat rate would’ve been 11p all the way through.
