Interstate Reliability Project approved


After extensive reliability studies conducted by ISO-New England (ISO-NE), the Regional Transmission Operator and system planning authority in New England, the Connecticut Siting Council (CSC) has approved the Interstate Reliability Project, concluding that the collaborative effort between Connecticut Light & Power Company's (CL&P) and National Grid is needed to address system reliability constraints in Connecticut and the region.

The CSC concluded that the project also has "economic and environmental benefits, and improves system integration both within Connecticut and the region as a whole." 

In addition to improved system reliability, the Interstate Reliability Project will provide the region's electricity customers with the infrastructure that is critical to a healthy economy, as well as access to cleaner, competitively-priced energy sources.

The Connecticut portion of the Interstate Reliability Project includes the construction of a new overhead 345-kilovolt (kV) transmission line on 37 miles of existing right-of-way from Lebanon, Connecticut, to the Rhode Island border in Thompson, and incorporates substation enhancements.

The Rhode Island and Massachusetts portions extend approximately 38 miles through National Grid's service areas.

The project is scheduled to be in-service by late 2015.
