If they're at the outlet village rather than the service station, maybe that will take the presssure off Applegreen and Ionity to reduce their prices! It could be a double whammy for Ionity if people (like me) catch on and give Ionity Carlisle a miss to head there. A bit nicer a place to stop than the service station too.
In that MacMaster video, which was last October I think, he connected to the Gretna Ionitys at a pretty low SoC - only time I've ever seen him start a charge on a 350 kw charger when his battery was low enough to get his maximum charging speed, and sure enough it went to 250 kw. But then, after ten minutes, the power cut. Something about insufficient grid supply. Cue tantrum. Also cue a lot of lost time faffing around to get reconnected, and in the end staying to go all the way to 100% on reduced power. Instead of realising he'd got enough in that ten minutes to get him to Abington or even the Fastned site at Hamilton. But I have wondered about the power supply to that area ever since. It's fairly rural, though not remote. I suppose they must think it's OK though.
