Great River Hydro – Comerford

Ivyland, PA – American Governor Company (AGC) has been contracted to supply equipment and site services to upgrade an existing GE Fanuc 90/30 in service on Unit #1 at the Great River Hydro‘s Comerford Station. The new system will functionally replace the existing gate actuator controller system. The governor oil system, gate position feedback, and PMG will be retained and reused without modification. Comerford Unit #1 is a 22MW Francis unit that had gate positioner controls provided by Sorensen. A recent NERC inspection indicated the installed equipment would not meet minimum frequency response. Installation is scheduled for early 2018.

Comerford Dam is a concrete dam in the Fifteen Mile Falls of the Connecticut River, on the border between New Hampshire and Vermont. The dam is near Monroe, New Hampshire. Construction began in 1928 and was completed in 1931. Comerford Reservoir is named after Frank D. Comerford, president of the Connecticut River Power Company and the New England Power Company.
