Available in PDF, EPUB and Kindle. Book excerpt: Texas National Energy Modeling Project: An Experience in Large-Scale Model Transfer and Evaluation reports on the Texas National Energy Model Project (TNEMP) experience. The TNEP was tasked with providing an independent evaluation of the Energy Information Administration's (EIA) Midterm Energy Forecasting System. It also provided recommendations to the Texas Energy Advisory Council concerning the maintenance of a national modeling system by the Council to evaluate Texas impacts within a consistent national modeling framework. The book provides all of the summary material documenting the entire experience, sequentially, from beginning to end. It first lays out the purposes of TNEMP, the organizational structure for the study, and an explanation of the evaluation criteria used to guide the model critiques. It summarizes in some detail the important findings of each of the 11 studies contained in Part II published under a separate cover. It presents the National Advisory Board’s assessment of the integrity of the evaluation project, their views of important outcomes of the TNEMP experience, and important recommendations to TNEMP and EIA. The final chapters contain an overview reply by EIA and a summary of a workshop held at the end of the project to discuss substantive issues raised by TNEMP.

Learning and Cost Reductions for Generating Technologies in the National Energy Modeling System NEMS
Download or read book Learning and Cost Reductions for Generating Technologies in the National Energy Modeling System NEMS written by and published by . This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes how Learning-by-Doing (LBD) is implemented endogenously in the National Energy Modeling System (NEMS) for generating plants. LBD is experiential learning that correlates to a generating technology's capacity growth. The annual amount of Learning-by-Doing affects the annual overnight cost reduction. Currently, there is no straightforward way to integrate and make sense of all the diffuse information related to the endogenous learning calculation in NEMS. This paper organizes the relevant information from the NEMS documentation, source code, input files, and output files, in order to make the model's logic more accessible. The end results are shown in three ways: in a simple spreadsheet containing all the parameters related to endogenous learning; by an algorithm that traces how the parameters lead to cost reductions; and by examples showing how AEO 2004 forecasts the reduction of overnight costs for generating technologies over time.
Download or read book Natural Gas Transmission and Distribution Model of the National Energy Modeling System written by and published by . This book was released on 1997 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Natural Gas Transmission and Distribution Model (NGTDM) is the component of the National Energy Modeling System (NEMS) that is used to represent the domestic natural gas transmission and distribution system. NEMS was developed in the Office of Integrated Analysis and Forecasting of the Energy Information Administration (EIA). NEMS is the third in a series of computer-based, midterm energy modeling systems used since 1974 by the EIA and its predecessor, the Federal Energy Administration, to analyze domestic energy-economy markets and develop projections. From 1982 through 1993, the Intermediate Future Forecasting System (IFFS) was used by the EIA for its analyses, and the Gas Analysis Modeling System (GAMS) was used within IFFS to represent natural gas markets. Prior to 1982, the Midterm Energy Forecasting System (MEFS), also referred to as the Project Independence Evaluation System (PIES), was employed. NEMS was developed to enhance and update EIA's modeling capability by internally incorporating models of energy markets that had previously been analyzed off-line. In addition, greater structural detail in NEMS permits the analysis of a broader range of energy issues. The time horizon of NEMS is the midterm period (i.e., through 2015). In order to represent the regional differences in energy markets, the component models of NEMS function at regional levels appropriate for the markets represented, with subsequent aggregation/disaggregation to the Census Division level for reporting purposes.

Available in PDF, EPUB and Kindle. Book excerpt: This report documents the objectives, analytical approach, and design of the National Energy Modeling System (NEMS) Renewable Fuels Module (RFM) as it relates to the production of the Annual Energy Outlook 1998 (AEO98) forecasts. The report catalogues and describes modeling assumptions, computational methodologies, data inputs, and parameter estimation techniques. A number of offline analyses used in lieu of RFM modeling components are also described. For AEO98, the RFM was modified in three principal ways, introducing capital cost elasticities of supply for new renewable energy technologies, modifying biomass supply curves, and revising assumptions for use of landfill gas from municipal solid waste (MSW). In addition, the RFM was modified in general to accommodate projections beyond 2015 through 2020. Two supply elasticities were introduced, the first reflecting short-term (annual) cost increases from manufacturing, siting, and installation bottlenecks incurred under conditions of rapid growth, and the second reflecting longer term natural resource, transmission and distribution upgrade, and market limitations increasing costs as more and more of the overall resource is used. Biomass supply curves were also modified, basing forest products supplies on production rather than on inventory, and expanding energy crop estimates to include states west of the Mississippi River using information developed by the Oak Ridge National Laboratory. Finally, for MSW, several assumptions for the use of landfill gas were revised and extended.
