Information determined through this model should only be viewed as illustrative, as market prices forecasts and values are subject to change and, when applicable to rates, will be determined in each 7(i) rate proceeding. In addition, BPA has not yet officially adopted in a 7(i) rate proceeding all aspects of the specific rate design reflected in these models. The RSS model denotes "faster" in the title because we removed the two worksheets referenced at the workshop that slow down the other version.
