I got two text messages from the electric company asking folks to reduce electricity usage in a space of 30 min. yesterday. I'm a small miner. 10 s9s but that represents about 12K worth of KW/h. Can they see this?
I shut them down last night just to be a good neighbor. I wouldn't want the whole street to be shut down because some in the Entergy control room saw me using so much electricity lol.
They know the load on the transformer.
And depending on you meter they may know it is you with out having to look at it.
