A comparison of ten models for computing the cost of hydrothermal energy is presented. This comparison involved a detailed examination of a number of technical and economic parameters of the various quantitative models with the objective of identifying the most important parameters in the...

MARKAL-MACRO is an experiment in model linkage for energy and economy analysis. This new tool is intended as an improvement over existing methods for energy strategy assessment. It is designed specifically for estimating the costs and analyzing the technologies proposed for reducing...

GEOCOM is a model developed to evaluate the cost effectiveness of alternative technologies used in the completion, production, and maintenance of geothermal wells. The model calculates the ratio of life-cycle cost to life-cycle production or injection and thus is appropriate for evaluating the...

This directory contains descriptions about each model, including the title, acronym, purpose, followed by more detailed information on characteristics, uses, and requirements. Sources for additional information are identified. Included in this directory are 35 EIA models active as of May 1,...

Electric utilities face a variety of uncertainties that complicate their long-term resource planning and acquisition. These uncertainties include future economic and load growths, fuel prices, environmental regulations, economic regulations, performance and construction cost of existing power...

Human and earth systems are extremely complex processes. The modeling of these systems to assess the effects of climate change is an activity fraught with uncertainty. System models typically involve the linking of a series of computer codes, each of which is a detailed model of some physical or...

This study is an effort to review existing information that is useful to develop an integrated model for predicting the performance of a radioactive waste facility. A summary description of 162 computer codes is given. The identified computer programs address the performance of waste packages,...

This paper describes a face validation process developed to assess computer models used in Phase I of the Theater Missile Defense (TMD) Cost and Operational Effectiveness Analysis (COEA) and to aid the COEA Study Director in making accreditation decisions for those models. The process was...

The Fossil2 energy-economic model is used by the US Department of Energy (DOE) for a variety of energy and environmental policy analyses. A number of improvements to the model are under way or are being considered. This report was prepared by the Pacific Northwest Laboratory (PNL) to provide a...

The impacts of completion practices on production and maintenance costs are considered. To evaluate alternative completion and workover technologies, a simple model has been developed that compares total well cost to total production or injection. The model is discussed briefly and results from...
