摘要

From 2014 to 2017,39 NPDs with 636 MW of cumulative capacity received an original licence to add a hydropower project, a significant increase from the 19 NPDs with 252 MW of cumulative capacity licensed in the previous eight years. The most common targets for NPD hydropower retrofits have been large capacity, low head, high flow navigation dams along major waterways. While a few dozen similar NPDs remain targets for development, thousands of undeveloped NPDs have small installed capacities and a primary purpose that is not navigation. Current trends suggest the economic development of these NPDs could be achieved using a cluster approach, where dams with similar head, flow, purpose, type, and location are retrofitted for hydroelectric generation using a standard plant design.
