CMP audit: Maine utility can improve, not 'irredeemably flawed' An independent audit of the management structure at Central Maine Power found the organization faces challenges but is likely equipped to overcome them. Author: Associated Press, Erin Keller (NEWS CENTER Maine) Published: 10:39 PM EDT July 12, 2021 Updated: 11:19 PM EDT July 12, 2021 MAINE, USA — An independent audit of the management structure at Maine’s largest power provider has found the organization faces challenges but is likely equipped to overcome them. The Maine Public Utilities Commission ordered the review of Central Maine Power’s management in January 2020. The order followed an investigation of the utility’s rates. Liberty Consulting Group of Lebanon, Pennsylvania, performed the audit of CMP, which is a subsidiary of Connecticut-based Avangrid. Liberty released its audit on Monday and found that Avangrid is not “a fundamentally or irredeemably flawed operation.”
