Project Summary:

The NSTAR Electric Company (NSTAR) Grid Self-Healing and Efficiency Expansion project involves the installation of significant new equipment for automation and management of the distribution grid. A network of new and existing switches, monitors, and reclosers are installed on selected circuits to provide the grid with the capability to automatically isolate grid power disturbances and to rapidly restore functional portions of circuits. New automated distribution equipment is also being deployed by the utility as a means to better manage power fluctuations on the grid, thus improving power factor and system energy efficiency.


- Distribution Automation Equipment for Approximately 400 out of 1,960 Circuits
--- Distribution Automation Communications Network
--- SCADA Communications Network
--- 360 Automated Distribution Circuit Switches
--- 109 Automated Capacitors
--- Equipment Condition Monitors

Targeted Benefits:

- Improved Electric Service Reliability and Power Quality
- Reduced Costs from Equipment Failures, Distribution, and Line Losses
