It's called a multiple-tariff meter. Of course it's easier to implement with modern electronics, but there's no reason you can't design an electromechanical meter device that has two different mechanisms to tally up "peak" and "off-peak" usage. I just did a quick Google search and found patents dating back to the 1970s.
- kennend3 4y agoI think you intentionally overlooked my point. I wasn't debating if these meters exist or not, it was that they were never used in Ontario. Continuing your logic, did Canada ever use these "multiple-tariff" meters? If they did, what was the point of the light the OP mentioned?
- teraflop 4y agoI certainly didn't intentionally overlook anything. I took your "doesn't make sense" to mean that you were questioning the possibility of an "old" meter accounting for different electricity rates at different times. Since it seems that's not what you meant, I apologize for misunderstanding you.

- tom_ 4y agoIndeed! More secure that way than trying to do it locally, probably, and now BST is somebody else's problem. But since it's been around since the late 70s, clearly you can do this without needing too much advanced tech - which is what I interpreted as being the perceived problem. (Perhaps incorrectly, but it looks like I wasn't the only one...)
