No one ever talks about the electricity demands for powering these things. Electric bills here in NJ via PSEG have spiked over 50% and they are blaming increased demand from datacenters, yet they don't seem to charge datacenters more?

A classic political games move, and it says more about how much anti-consumer nonsense is tolerated in New Jersey than it does about power generation and distribution pricing realities.

The data centers will naturally consolidate in areas with competitive electricity pricing.

This is called marginal pricing. Everyone pays the price of the marginal producer.

In some cases they try to get the data centres to pay for their infrastructure costs but the argument is that customers don't pay this normally but do so through usage fees over time.

That is on NJ government for allowing the price increases. They can easily say no.
