New England Clean Energy Connect
ISO-NE ↔ Hydro-Québec · HVDC line (voltage-source)
An HVDC line from the Québec border through western Maine to a converter at Lewiston, joining the New England grid at Larrabee Road.
Operator readings
Compare each operator’s reading at its stated time. Scheduled transfers and metered physical flow measure different things.

Hourly readings, signed so that up is power leaving the market. Each series identifies whether it measures flow or a transfer schedule.
Above zero: ISO-NE → Hydro-Québec. Below: the reverse.

Sources and method
Readings come from ISO-NE interface readings. Each value is shown with its operator and source time; direction is normalized from that operator’s sign convention toward or away from ISO-NE. A rating describes the equipment; an operator’s posted directional limit, when available, is a separate operating value. The map point identifies a sourced terminal or crossing where available, or a representative connection point; it does not trace the full route.
