Preface
The analysis in this report was undertaken at the request of
Senators James M. Jeffords (I-VT) and Joseph I. Lieberman (D-CT), subsequent
to the report Analysis of Strategies for Reducing Multiple Emissions from
Power Plants: Sulfur Dioxide, Nitrogen Oxides, and Carbon Dioxide, published
by the Energy Information Administration (EIA) in December 2000. The analysis
in the December 2000 report was expanded in the report Analysis of Strategies
for Reducing Multiple Emissions from Electric Power Plants: Sulfur Dioxide,
Nitrogen Oxides, Carbon Dioxide, and Mercury and a Renewable Portfolio Standard,
published by EIA in July 2001. Senators Jeffords and Lieberman requested that
EIA consider the impacts of technology improvements and other market-based
opportunities on the costs of emissions reductions, as noted in the letter
in Appendix A.
This study analyzes the costs and impacts of a set of emissions
control limits for electricity generators under four different technology
cases. Limits are defined for sulfur dioxide, nitrogen oxides, mercury, and
carbon dioxide emissions by 2007 and are the same for each case. The limits
are analyzed using the reference case and the high technology case assumptions
for end-use demand, supply, and generation technologies in EIAs Annual
Energy Outlook 2001, published in December 2000, and the moderate and
advanced policy cases from Scenarios for a Clean Energy Future (CEF),
a publication of an interlaboratory working group, published in November 2000.
The projections in this report were produced using the National Energy Modeling
System (NEMS), an energy-economy model of U.S. energy markets designed,
developed, and maintained by EIA, which is used each year to provide the projections
in EIAs Annual Energy Outlook. The energy market results are
provided in Appendix C for the reference and advanced technology cases and
in Appendix D for the cases based on CEF.
The legislation that established EIA in 1977 vested the organization
with an element of statutory independence. EIA does not take a position on
policy questions. It is the responsibility of EIA to provide timely, high-quality
information and to perform objective, credible analyses in support of the
deliberations of both public and private decisionmakers. This report does
not purport to represent the official position of the U.S. Department of Energy
or the Administration.
Within its Independent Expert Review Program, EIA arranged
for leading experts in the field of energy and economic analysis to review
an earlier version of this report. All comments from the reviewers either
have been incorporated or were thoroughly considered for incorporation. As
is always the case when peer reviews are undertaken, not all the reviewers
may be in agreement with all the methodology, inputs, and conclusions of the
final report. The contents of the report are solely the responsibility of
EIA. The assistance of the following reviewers is gratefully acknowledged:

The projections in the reference case in this report are not
statements of what will happen but of what might happen, given the assumptions
and methodologies used. The reference case projections are business-as-usual
trend forecasts, given known technology, technological and demographic trends,
and current laws and regulations. Thus, they provide a policy-neutral reference
case that can be used to analyze policy initiatives. EIA does not propose,
advocate, or speculate on future legislative and regulatory changes. All laws
are assumed to remain as currently enacted; however, the impacts of emerging
regulatory changes, when defined, are reflected. |
