Proposed commercial operation date per queue filing
The proposed Solar project, identified as ISO-NE-1100 in the ISO-NE interconnection queue, is a 164.56 MW solar generation project located in Somerset County, Maine. The project consists of 164.56 MW of solar photovoltaic generation. Its queue entry date is February 19, 2021, with a proposed commercial operation date of March 31, 2028. As of the latest data, the interconnection agreement (IA) status is "Not Started".
The proposed point of interconnection (POI) is on Central Maine Power's 115 kV line Section 82 (Athens – Hartland), approximately 7.5 circuit miles to Athens Substation and approximately 4.3 circuit miles to Hartland station, with approximate coordinates 44.8759 N, 69.5423 W. The project has been mentioned in recent news coverage related to regulatory matters.
