The Mica Dam is an earth-filled dam operated by BC Hydro. It is located on the Columbia River approximately 140 km north of Revelstoke, British Columbia. Mica is one of four dams that regulate the flow of the Columbia.
The Mica Generating Station consists of four generating units contained within an underground powerhouse adjacent to the dam. Mica has an installed generating capacity of 1,805 MW and was originally designed with the provision for two additional units. The underground powerhouse was the largest in the world at the time of its construction in 1973. Significant construction activities are now occurring at the Mica site as a part of the Turbine 5 and 6 projects. These units will add approximately 1000MW of additional capacity. When the project is completed, Mica will be BC Hydro's largest facility.
The supply, installation, and commissioning of a Heating, Ventilation, and Air Conditioning (HVAC) system was required within the generating station to ensure airflow and air quality remain acceptable during construction activities. The project was completed on a strict timeline with the operation of the generating station taking priority for the duration of the contract.
