In Texas, one company maintains the infrastructure and a variety of companies compete to provide service to customers. Separating these concerns means cheap, reliable electricity. Power is quickly restored after natural disasters and we don't have brownouts during the summer. Electricity is affordable and we don't pay extra during peak hours.
I pay $0.10/kWh for a plan 100% provided by wind power. When power is in demand, the smart meter my electric company provided for free (with free installation) will adjust my thermostat and give me a credit on my bill (under a program I opted into).
If my state made me pay $0.40/kWh for unreliable energy, I'd be furious.
