In my EI blog post today, I discuss the CA debate over how to return some of the cap and trade revenue to households and explain why I think a fixed rebate for every household the utility serves should be replace by a discount per-kilowatt-hour.

Canary media correct that MA elec rate is way above MC, bc much of price pays for infrastructure that is not constrained except at peak hour, so high price distorts customer behavior. So true for heat pumps. Also for excessive incentive to install rooftop solar.
