OPEN HOUSE Learn more about Algonquin Gas Transmission, LLC's Reliable Affordable Resilient Enhancement Algonquin Gas Transmission, LLC ("Algonquin") invites you to attend upcoming Open Houses for the proposed Reliable Affordable Resilient Enhancement ("AGT Enhancement"). This is a targeted enhancement of existing pipeline infrastructure which is designed to upgrade Algonquin's existing system within, or adjacent to, existing rights-of-way. This Algonquin enhancement will center around already existing infrastructure and will not require the construction of any new compressor stations. Within Massachusetts, pipeline enhancements will occur in the towns of Mendon, Bellingham, Franklin and Wrentham. Upgrades in Rhode Island will take place in Cumberland, Little Compton, Tiverton and Burrillville. Subject to receipt of all necessary regulatory approvals, this work is expected to take place in 2028, with an in-service date expected in late 2028.
