Transmission

Our electric transmission system — more that 4,000 miles of overhead and underground high-voltage wires and substations — plays an essential role in connecting customers across New England with reliable, affordable power.

The power grid is undergoing significant change to achieve carbon reduction targets outlined in state and regional policies, and help us achieve our own goal to have carbon-neutral operations by 2030.

The power grid is the interconnected network that delivers electricity from where it’s generated to where it's consumed.

We continue to ensure the grid is ready to meet an increase in demand from electrification, while also making significant investments that enable our transmission system to integrate clean energy resources, detailed in our 2020 sustainability report

Investments in the power grid have three key benefits:

Reliability: The ability to meet the electric demand and energy requirements of customers at all times
Resiliency: The ability to harden the power grid to prevent damage from extreme weather and other disasters
Clean Energy: Connecting a growing number of clean resources to the grid and ensuring we’re ready to meet an increased electric demand

Projects

These key focuses are achieved through projects that maintain and upgrade our system, as well as help connect clean energy resources to the grid. They also help meet customer demand for power where and when it's needed.

Distribution 

Transmission and distribution work together to deliver energy.

The large transmission lines move electricity over long distances from the supplier to a substation. From there the distribution lines carry the electricity to your home or business.  

We are constantly upgrading  our systems to reroute and restore service to our customers as quickly as possible.
