Reliable Service and Projects
Living in America’s most forested state is incredibly special, but it also presents challenges. CMP is building a smarter, stronger, more resilient grid for Maine. We have invested $3 billion to improve our infrastructure over the last decade – ensuring that Mainers can power on.
- New, stronger power lines that resist fallen trees and branches
- New, sturdier poles that weather Maine’s toughest storms
- New animal guards to keep Maine’s wildlife safe and prevent outages
- Tree care plans to mitigate damage
- New automation to reduce outage impacts

Electric Projects
Automation Program
Central Maine Power (CMP) is investing in smart technology upgrades to improve service in your community and reduce the length of time customers may experience a power outage. This work is crucial as Maine faces more extreme storms that may potentially impact the state’s energy grid.

Structure Replacement Program
Central Maine Power (CMP) is investing in transmission line upgrades to continue providing our customers safe, reliable service and strengthen Maine’s energy grid. This is especially important as our state experiences more extreme weather and storms.
Transmission lines, along with substations, are the backbone of CMP’s grid serving large numbers of customers. Our company regularly inspects our lines to ensure each component is performing according to standards.

Other Projects
Operations
Maintenance operations on existing utility equipment and associated land which may include operating, maintaining, reconstructing, inspection, testing, restoring, removing, and repairing.
- Distribution Line Inspections
CMP inspects every pole on our distribution line system for structural integrity once every five years and corrects any deficiencies by replacing poles and cross arms and transferring lines. These inspections and replacements improve system reliability and helps CMP meet regulatory requirements.
Interconnection Projects
CMP efficiently delivers safe, reliable electricity to more than 646,000 homes and businesses from an energy supplier of their choice over our dependable infrastructure. CMP does not generate power.
CMP works with small and large power generators to connect their facilities to our energy grid. Energy generators and developers pay the expenses associated with CMP’s system improvements to facilitate their connection needs. Projects may require a new substation, transmission line, switch yard, or other infrastructure to safely connect to the grid.
- Larger Generation, Energy Storage
- Distributed and Community Generation
Many CMP customers are subscribing to renewable energy programs, including community solar generation, a form of distributed generation. CMP does not develop these generators. We are committed to interconnecting the generators while ensuring a safe, reliable energy delivery grid for our customers. Learn more about CMP’s role in the links below.
