NLR Modeling Shows Coordinated Operation Could Boost Mid-Columbia Hydropower Efficiency

A new study using NLR modeling indicates that coordinating the operation of hydropower plants along the Mid‑Columbia River could improve overall system efficiency. The research highlights that in a cascaded system—where multiple dams are owned and operated by different entities—collaboration is essential to align operational goals. By synchronizing water releases and turbine usage, the model projects a measurable increase in energy output across the network. The findings suggest that operators will need to establish joint operating protocols to capture these gains, potentially reducing downtime and maximizing renewable generation.
