Interesting...Thank.
The Canadian grid system is not all connected together. The Electrical Utility is control by the provinces, not federal. The city I live - Toronto, it is control by Toronto Hydro - in Ontario, it is control by Hydro One, and I pay the City of Toronto for my electrical bills - BTW, one is coming at the end of this month. In Quebec, it is control by Hydro Quebec, in New-runswick, it is control by NB Power. Same for the rest of Canada.
About a monitor web site like in your example ? That, I don't know...I have to Google it.
