Project : TransCanada Energy/Irving Oil Grandview Cogeneration Plant

AECON Industrial — Saint John, New Brunswick

The existing Irving Oil Refinery steam generating facilities (two fired-boilers/HRSGs) were converted to a cogeneration plant by the addition of two new GE LM6000PD natural gas-fired, dry low-NOx gas turbine generator packages and auxiliary equipment, including gas compressors, steam and glycol systems, continuous emission monitoring systems, and exhaust ducts with bypass stacks.

The 50 MVA units were connected via unit transformers to the Irving Oil 138-34.5 kV transformer substation. The plant is capable of islanding with the refinery loads and black start during utility grid failures. The black start units were arranged to synchronize with the NB Power system across a choice of 34.5 or 132 kV breakers.

Initially appointed as owner's engineer for the cogeneration project, CHA Canada provided conceptual design and project definition engineering including project cost estimate. We also completed the design-build contract bid specifications and provided technical coordination. During the project implementation phase, CHA Canada provided detailed design engineering for the engineering, procurement, and construction (EPC) contractor.
