Wholesale power and transmission rate projections 1993--2014 and historical wholesale power rates 1939--1992

摘要

This document provides a range of high, medium, and low case long-term projections of Bonneville Power Administration's (BPA) wholesale power rates and a medium case long-term projection of BPA's wheeling rates. These projections are produced annually by BPA. BPA uses these projections in long-term marketing, resource, transmission, and financial planning assessments. BPA's projections also are used by public utility commissions, utilities, and others for a variety of planning purposes. The analysis used for these rate projections assumes that current rate making methodologies continue into the future and are further based on certain assumptions about regional loads, extra-regional markets, the costs of resources, BPA's financial requirements, and the capability of the region's power plants. While these projections are intended to address the overall uncertainty in rate levels, BPA realizes that the future will not reflect any specific set of assumptions. The rate projections in this document have been prepared prior to the Draft 1993 BPA Marketing Plan, the implementation of which is almost certain to push BPA away from any set of assumptions in this document. Therefore, this document can be thought of as representing the ''old'' BPA with its products and policies. It can be viewed as a starting point or reference point to measure the impact of the ''new'' BPA with its Marketing Plan, and the broader undertaking referred to as the Competitiveness Project.
