Greater Portland Transmission Upgrades Projects
Central Maine Power (CMP) is proposing the Greater Portland Transmission Upgrades Project, a multi-year initiative to build a modern network of substations, upgraded infrastructure, and strengthened grid sections stretching from Yarmouth through Greater Portland.
These improvements are designed to:
- Replace aging equipment.
- Expand capacity to meet growing electricity demand.
- Enhance the reliability of the electric system for more than 200,000 customers.
Although early in the process, this project aims to support this region’s future energy needs as more heat pumps, electric vehicles, electrified water transportation and renewable energy are utilized by our customers.
