Ivyland, PA – American Governor Company (AGC) has been awarded a contract by New Brunswick Power to supply Upgrade Kits very similar to the equipment provided for the Beechwood retrofits. AGC will provide all equipment necessary for governor conversion to PLC control, including all necessary terminal blocks, relays, wire markers, etc. for a complete and finished installation. Presently, Mactaquac’s power plant has six Kaplan Turbines, these units were provided with Woodward Analog Electric Governors in 1966 and 1977.
