About

The Solar project, identified as ISO-NE-1245 in the ISO-NE interconnection queue, is a proposed 150 MW solar generation facility in Hartford County, Connecticut. The project, consisting of 150 MW of solar capacity, entered the queue on March 31, 2022, with a proposed commercial operation date of November 1, 2028. Its interconnection agreement status is listed as "In Progress (unknown study)".

The proposed project's point of interconnection (POI) is the 345kV Line 3419 Tap between Meekville Junction/Barbour Hill (PSSE Bus Number: 119103) to Ludlow (PSSE Bus Number: 116045). The project has been mentioned in recent news coverage related to industry and regulatory matters.
