The Maine Public Utilities Commission announced Thursday that it has opened an investigation into the management practices of Central Maine Power and its parent company Avangrid.

The Maine PUC said it will focus on how revenue considerations influence decision-making by CMP and Avangrid, the potential consequences for CMP’s customers, and how to better align incentives through regulatory oversight.

Last September, the PUC said it launched a summary investigation into management issues surrounding the CMP.

The commissioners directed the CMP to file a plan to address the issues and concerns raised in a performance audit report.

The PUC said CMP filed a plan in November that included significant changes to its management structure.

“CMP is directly impacted by Avangrid’s decision making and investment planning. While we’ve seen an improvement in CMP’s performance, we want to make sure it’s sustainable,” said Board Chairman Philip L. Bartlett II. “At the heart of this issue is whether Avangrid’s decision-making about how to direct resources to CMP is misaligned with the interests of taxpayers and whether regulatory changes are needed to protect CMP’s customers.”

CMP released a statement on the investigation saying it was not the same company as it was four years ago and had made many changes to improve its performance.

“CMP has demonstrated steady improvement in customer service, a serious commitment to safe and efficient storm response, and has consolidated its operations under the leadership of Maine-based leaders, including the creation of a new community relations organization. We have consistently met the service performance standards for two years, generally agree that the performance standards are good for customers, and we will cooperate with this area of ​​further investigation by the Commission while remaining focused on satisfying and exceeding the needs of our everyday Maine customers and support clean energy goals,” the statement read.
