Strengthening Reliability for Branford, Guilford
When severe weather strikes, the strength of the electric grid can make all the difference.
To help protect electric service for approximately 17,000 customers in Branford and Guilford, we completed important flood mitigation upgrades at our Branford Substation.
By strengthening critical infrastructure against potential flooding, we're investing in a more reliable energy future and ensuring our communities are better prepared for severe weather events.

Preparing for extreme weather
As weather patterns continue to change, we must prepare for increasingly intense storms and flooding events.
Following Superstorm Sandy, we looked at how severe weather could affect critical infrastructure across our system. While the Branford Substation continued operating during the storm, flooding from a nearby river reached the perimeter of the property reinforcing the importance of planning for future severe weather events.
As part of a statewide initiative launched in 2019, the Branford Substation was identified as one of several facilities where proactive flood mitigation investments could further strengthen reliability for customers.
Branford Substation Improvements
We completed several upgrades that provide multiple layers of protection designed to keep essential equipment operating when you need it most.
That means lowering the chance of potential outages during storms, and faster system recovery from major weather events.
Flood protection wall
A reinforced flood wall was installed around the substation’s control building to help protect critical equipment during major storm events and flooding conditions.

Elevated electrical equipment
Key outdoor electrical equipment was raised above projected Category 3 hurricane flood levels, helping reduce the risk of damage during severe weather.
If severe weather is forecast, a backup generator can be installed on elevated ground to help ensure the sump pump and other critical control systems continue operating, even if normal power sources are interrupted.

Enhanced water management systems
Additional drainage and pumping capabilities were incorporated to help manage water and protect critical infrastructure if flooding occurs.
Building a More Resilient Grid
These upgrades are part of a broader effort to modernize and strengthen the electric system across our service territory.
By investing in infrastructure improvements before they’re needed, we’re helping ensure the grid is better prepared for future weather challenges while continuing to deliver safe, reliable electric service to our customers.
