Hydropower Coping Zones

Peter Yee;Steve Rose
Coping zones were developed to identify the water level, flow, plant diversion, and other physical factors, such as ice and meteorological conditions, affecting hydropower production. Coping zones were developed for each hydropower plant at the outlets of Lake Superior, Lake Erie (including those in the Niagara River and Welland Canal), and on the St. Lawrence River to provide a wide perceptive of operating experience and how plant operators cope with problematic conditions. Based on a literature review and consultation with plant operators, investigators developed coping zones for each hydropower plant, where Zone A is a range of levels and flows that the operator would find tolerable; Zone B is a range of level and flow conditions that would have unfavourable though not irreversible impacts; and Zone C is a range of water level conditions that would have severe, long-lasting or permanent adverse impacts on the plant.
