Projects

Turbine Injection Skid
ONEC provided design and construction services for a water injection skid to supply de-ionized water to the NOx skid at the client’s power plant. Working from the client’s conceptual design, ONEC undertook a detailed design of an integrated storage/production/recirculation system to maintain the high purity of de-ionized water during storage. The water injection skid was fabricated at ONEC’s panel shop in Edmonton.
Involvement: Electrical Engineering, Mechanical Engineering, Fabrication

Mine 480V Services
ONEC worked with a client to supply 480 V main service entrances for their mine near Wabamun, Alberta. The project also included the installation of 300 kVA and 150 kVA transformers, including the provision of engineered drawings.
