I get emails from my power provider on occasion asking me to opt-in to some program that charges based on usage rather than at a fixed rate. The email basically just says "most people see lower rates" and "use less power at peak times to save money" and says precisely nothing about tail risk. Could my bill go up 100x? I would have no idea.
Yes, buying using the wholesale price incurs risk. But these programs aren't marketed like short selling or options trading - risky decisions for professionals. They are marketed as cost savings measures.
