I was just listening to @tomraftery on GreenMonk TV, he referenced a story about PG&E in the US and seriously failings in the Smart-meter roll-out.
It revolves around the excessive consumer bills that arose in the summer months due to HVAC units running in peak hours, as of course they would, we cannot store "coolness" very easily yet.
Tom pointed out that Utilities have never been good at communication, which is true, some marketing stuff, but nothing about tariffing or technology.
So I am adding this post to alert the need for Smart-meter roll-out to have a comms element, comms to the user, not just to the computer. Lots of opportunities here. Should be a good topic for a HomeCamp workshop.
