Customer system efficiency improvement assessment: Supply curves for transmission and distribution conservation options

Description: This report documents the results of Task 6 in the Customer System Efficiency Improvement (CSEI) Assessment Project. A principal objective of this project is to assess the potential for energy conservation in the transmission and distribution (TandD) systems of electric utilities in the BPA service area. The scope of this assessment covers BPA customers in the Pacific Northwest region and all non-federal TandD systems, including those that currently place no load on the BPA system. Supply curves were developed to describe the conservation resource potentially available from TandD-system efficiency improvements. These supply curves relate the levelized cost of upgrading existing equipment to the estimated amount of energy saved. Stated in this form, the resource represented by TandD loss reductions can be compared with other conservation options and regional electrical generation resources to determine the most cost-effective method of supplying power to the Pacific Northwest. The development of the supply curves required data acquisition and methodology development that are also described in this report. 11 refs., 11 figs., 16 tabs.

Load management alternatives to transmission and distribution construction: Toledo-Wren case study

Description: This paper describes the development of a method to predict the feasibility of using load management as an alternative to construction of transmission and distribution capacity. A forecasting model was developed and applied to a particular case. Several problems were identified in the test case, necessitating modification of the model. The authors conclude that the modified version of the model allows accurate assessment of the effects of load management and conservation measures on transmission capacity. 13 figs. (JDH)
