ERO 019-5816 – Development of a Clean Energy Credit Registry

The total amount of GHGs emissions from a hydroelectric facility is dependent upon many factors, including the impounded reservoir, terrain, amount of organic matter, air-water temperature, reservoir depth and size, vegetation (algae and plant/tree litter), pH values, oxygen levels, flow velocity, water level fluctuations, wind speeds, precipitation, wetlands within the impoundment zone, and facility operating strategy (cycling and peaking to maximize power generation).  Every hydroelectric facility is unique in its complexity and must be carefully studied and continually assessed and monitored to determine the total daily, seasonal and annual GHG emissions per MWh emanating from the system.
