HH Angus was engaged to provide design services for the construction of a cogeneration facility at a Sonoco facility in Ontario. The natural gas-fired plant plant was designed to provide steam, electricity and emergency power; it produces 115,000 lbs/hr of thermal energy in the form of steam for the Sunoco Canada Trent Valley Paper Mill located in Trenton, Ontario. The facility is connected to Hydro One Networks Inc. and supplies 44 kV at the Sidney T.S., which feeds into the Ontario electricity market administered by the Independent Electricity System Operator.

This project was a turn-key, design build, with all interactions between the project consultants carried out in accordance with ISO 9000.  HH Angus provided prime consulting services for the design of the building, foundations, electrical interconnections, mechanical equipment and plant layout.

HH Angus was involved from the beginning of the project, assisting the client to form the project’s objectives and design brief. Included in the our scope was the procurement of all the equipment. Extensive experience in cogeneration design made HH Angus an obvious choice as consultant for this project. We also had previous design experience with Solar Turbines Inc., and the tight timeline and schedule made the selection of an experienced engineering firm paramount.

As the project required integration with existing facility, our broad portfolio in central plant design and industrial environments were key to the project’s success. The boiler and turbine were interconnected to the main plant and programmed to provide optimum operating conditions.
