Federal Response:
Hydroregulation (regulating water) is the process planners and operators use to make decisions about routing water through a series of dams in a river system. Computer hydroregulation modeling is used to simulate operations for the system of dams that operate for multiple purposes, including flood risk management, hydropower, irrigation, navigation, recreation, water supply, and fish and wildlife purposes. Two hydroregulation models were used to simulate operations in the basin in support of the Hydraulics and Hydrology analysis: Hydro System Simulator (HYDSIM) and Hydrologic Engineering Center Reservoir System Simulation (ResSim) software. The models mesh together through multiple steps to simulate operations in the Columbia River Basin. More information on these models is available in Section 3.2 and in Appendix B of the Draft EIS.

AURORA is a production cost model that uses loads and resource projections to calculate wholesale markets for the West. The model estimates how much power can be sold into the wholesale market and estimates the related prices. Appendix I, Hydroregulation, and Appendix J, Hydropower, provide detailed information on this model. This analysis relies on the hydroregulation modeling.

To analyze the power system reliability Bonneville uses the GENeration Evaluation SYStem (GENESYS) model, which simulates regional power generation and demand.

Federal Response:
Bonneville staff have the expertise to run the GENESYS model and describe its outputs for the CRSO EIS. Bonneville has worked with the Northwest Power and Conservation Council (Council) on developing the model for many years. For areas of the CRSO EIS power analysis where Bonneville staff did not have expertise, Bonneville hired consultants; however, for the GENESYS model, this expertise is housed within Bonneville.

The Council received periodic updates on the CRSO EIS NEPA process similar to the general public. Since the Council is not a Federal, Tribal, state or local agency, it could not serve as a cooperating agency under NEPA. The Council received the Draft EIS when it was available for public review.
