So Cal Edison is trying to even things out amongst it's customers. Back during the energy crisis, the way rates were set-up, high usage customers paid even more in overall costs, and low-usage customers paid way less than they should have. That means high usage customers have been unfairly shouldering the load, paying $600 million more per year than they should have. So, Edison is coming up with a new rate structure that balances it all out. If you're a low usage customer your $36 monthly bill would go up to $51, average usage customers bill would go from $91 to $102 per month, and a high usage bill would go from $187 down to $168.
