On top of the "The Electric Home Rate Plan includes a $15-per-month Base Services Charge"... because people were starting to get 100% of their power from solar and it was "unfair".
Connecting infrastructure costs roughly the same to maintain regardless if 10 amps or 1000 amps is running through it. The crypto miner pays the same fee for their standard service connection then pays per Kwh just like everybody else. Other customers are not subsidizing their connection nor their power.
By your logic, you are subsidizing anyone who uses more power than you and you are being subsidized by anyone using less power than you.
Connecting infrastructure costs roughly the same to maintain regardless if 10 amps or 1000 amps is running through it.
That's simply false. A 1000A transformer costs considerably more than a 10A transformer, both to purchase and to service.
By your logic, you are subsidizing anyone who uses more power than you and you are being subsidized by anyone using less power than you.
That is only true if the "connection fee" (distribution charges) are the same for both the 10A user and the 1000A user. When the charge is divided up on the basis of a user's actual consumption, it is not.
A 1000 A transformer costs more than a 10 A transformer
Yes. And that is true regardless of how heavily it is used, which means you should pay a flat rate for maintenance of the infrastructure you use, and another rate for the power you draw.
Residential buildings use standardised infrastructure, which then leads to the same standard fee for everyone. Industry that needs heavier equipment pays a different fee, because they require different infrastructure.
The transformer is dimensioned based on the max capacity of the houses in the neighbourhood
No, it isn't. They use considerably smaller, cheaper transformers, based on the maximum expected load. A 500A transformer might serve ten 200A users. They do not have the capacity to provide full, rated service to all users simultaneously.
Those ten users might never use more than 400A total, even though each of them might use 150A+ from time to time. It doesn't make sense to install a 2000A transformer when it will never see more than 400A.
