Last week, Michael Peevey, president of the California Public Utilities Commission, announced that he was stepping down from his position at the end of the year. His resignation comes amidst an investigation into an overly cozy, cash-rich and influence-filled relationship between regulators and utility executives at Pacific Gas and Electric. The website SFGate quoted Tom Long, a lawyer with The Utility Reform Network, as saying, “This is nothing less than quid pro quo deal-making with ratepayer dollars." He continued, “I honestly have never seen such smoking-gun evidence of corruption at the highest levels of the commission.” A CPUC spokesman "denied that...Peevey had promised anything to PG&E in exchange for regulatory favors," according to the website.
