CMP Meets 2023 PUC Mandated Reliability Metrics

New data comes as the company prepares to submit its first ever “performance report card” to the Maine PUC, just one component of the Governor’s Utility Accountability bill 

AUGUSTA, ME — February 5, 2024 — Central Maine Power (CMP) announced today that it exceeded reliability metrics requirements set by the Maine Public Utilities Commission (MPUC) in 2023. This announcement comes as the company prepares to submit its first ever “performance report card,” which is part of the Governor’s Utility Accountability and Grid Planning (LD 1959) bill passed in the last legislative session. 

Monday’s announcement also comes after CMP submitted its Climate Change Protection Plan to the Maine PUC at the end of 2023, another requirement under the new law.  

“As we work towards building a smarter, stronger, and more resilient grid to improve reliability for our customers and address climate change, we are pleased to have exceeded challenging reliability requirements set by the Maine PUC in 2023,” said Jon Breed, spokesperson for CMP. “Additionally, the Governor’s Utility Accountability bill, which passed in the last legislation session, made several meaningful changes to utility regulation to help move the state forward. We support these changes, and we look forward to continuing our collaborative work with so many stakeholders who have been brought together by this new law.”

The MPUC tracks three main categories: System Average Interruption Frequency Index (SAIFI), System Average Interruption Index (SAIDI), and Customer Average Interruption Duration Index (CAIDI). These metrics, along with other metrics including customer service performance, will be submitted by CMP to the MPUC in the form of a “performance report card” this spring.
 

 

System Average Interruption Frequency Index (SAIFI): The average number of interruptions that a customer would experience in a one-year period. Missed target would result in financial penalty. 

System Average Interruption Duration Index (SAIDI): Total time an average customer experiences a non-momentary power interruption in a one-year period. Missed target would result in financial penalty. 

Customer Average Interruption Duration Index (CAIDI): Average time required to restore service to the average customer per sustained interruptions, measured in minutes or hours of interruptions. Missed target would result in financial penalty.
