Central Maine Power shareholders, not ratepayers, are going to foot the $580,000 cost of an audit that found problems with the way the utility handled customer service issues with its new billing system.

The Maine Public Utilities Commission voted Thursday to hold shareholders accountable for the full cost of the audit by Liberty Consulting Group of Pennsylvania. Under Maine law, ratepayers typically pay the full cost of a management audit but there's an exception if an investor-owned public utility like CMP results in a finding of "imprudence."

The electric utility Emera Maine and its would-be Canadian buyer Enmax are proposing millions of dollars in rate relief for customers — if the deal goes through. But some state lawmakers are calling on regulators to take their time setting terms for the $1.2 billion deal.

Based on the headlines, it would be easy to think that the Maine Public Utilities Commission spends all of its time addressing issues regarding CMP. But the PUC impacts the lives of Mainers in many other ways.  It regulates electric, gas, telephone and water utilities as well as setting rates that are mandated to be just and reasonable for all ratepayers. The Chairman of the PUC and the Manager of the MPUC Customer Assistance Division join us to answer questions about the work the PUC does and the utilities they regulate.
