Effective Regulation of Public Utilities

Political philosophers ask this question:  Suppose that at the time of your birth, you did not know your future:  whether you would grow up to be a utility CEO, a coal-company shareholder, a gas pipeline owner, a renewable energy developer, a regulatory professional, a small residential consumer or a major automobile manufacturer.  You knew not if you would be rich or poor.  Now suppose that in that condition of utter ignorance, you could choose the principles that would apply to regulated industries.  What principles would you choose, so that no matter what position you later attained, you would be treated fairly?
 
I suggest you would choose these nine principles.
