Abstract

The proposed Clean Power Plan gives U.S. states flexibility in how they attain state-level carbon dioxide emissions rate goals from existing power plants. This analysis explores the potential impact of the proposed CPP on Southeast states across a range of compliance options relative to a baseline without the CPP. The analysis presents modeling results from the Dynamic Integrated Economy/Energy/Emissions Model for eight primary compliance scenarios involving rate-based or mass-based compliance, unilateral state action or regional cooperation, and inclusion or non-inclusion of natural gas combined cycle (NGCC) units as regulated entities under the CPP.

Regarding electricity sector adjustments, the modeling shows that a rate-based approach initially decreases coal generation, encourages use of existing and construction of new NGCC units, and incentivizes renewable generation, although use of renewables is not cost-effective in the Southeast under baseline cost assumptions. By comparison, a mass-based approach initially increases coal generation and removes incentives for use of existing NGCC units while significantly increasing new NGCC generation. Including new NGCC units under CPP compliance shifts generation from those units to existing NGCC units under mass-based compliance and increases coal generation under rate-based compliance.

Regarding policy costs, the modeling shows that individual state compliance costs vary considerably, that a mass-based approach initially entails half the costs of a rate-based approach, and that both regional rate-based and mass-based approaches create significant net cost savings over unilateral state compliance.

Martin Ross

Research Scientist, Senior

Martin Ross is a senior research economist at Duke University's Nicholas Institute for Environmental Policy Solutions, specializing in environmental and energy economics and macroeconomic-simulation modeling.

Prior to joining the Nicholas Institute at the end of 2011, he worked with RTI International where he developed the Applied Dynamic Analysis of the Global Economy (ADAGE) model, which is used by the U.S. Environmental Protection Agency (EPA) to respond to Congressional requests for legislative analyses. The ADAGE model can investigate many types of economic, energy, environmental, and trade policies at the international, national, and U.S. regional levels. It is particularly useful for examining how climate-change mitigation policies limiting carbon dioxide (CO2) emissions from energy consumption and non-CO2 greenhouse gas (GHG) emissions will affect all sectors of the economy, altering industrial and residential energy consumption and efficiency. Research conducted for the U.S. EPA Climate Change Division, the Stanford Energy Modeling Forum, and the Pew Center on Global Climate Change has involved using the ADAGE model to estimate U.S. macroeconomic impacts of legislative proposals to reduce GHG emissions. Other modeling by Ross has included developing a detailed technology model of electricity markets to examine how criteria pollutant and GHG policies affect capacity planning decisions and generation costs.

Prior to joining RTI, Ross spent several years at Charles River Associates where he developed regional models to look at effects of climate-change mitigation policies and macroeconomic impacts of electric-utility legislation. In addition to his legislative analysis, Ross has advised industry groups such as the Electric Power Research Institute and Edison Electric Institute on economic and electricity modeling, and is published in The Energy JournalEnergy Economics, and Climactic Change, among others.

Ross holds both a doctoral and master's degree in economics from the University of Colorado, Boulder, and a bachelor's degree in economics from Michigan State University.

Brian Murray

Research Professor in the Division of Environmental Sciences and Policy

Dr. Brian C. Murray is Director of the Nicholas Institute for Energy, Environment & Sustainability, Research Professor at the Nicholas School of the Environment (primary) and Sanford School of Public Policy (secondary), and Faculty Associate of the Duke Initiative for Science & Society. In 2015 he was Fulbright Visiting Research Chair in Environment and Economy at University of Ottawa’s Institute of the Environment.  He is widely recognized for his work on the economics of energy and climate change policy, including the design of market based mechanisms to reduce greenhouse gases and deploy low-carbon energy. Members of the United States Congress, state legislators and regulators have sought the counsel of Dr. Murray and colleagues in developing energy and climate legislative proposals and regulatory options.  Their development of the cost containment reserve mechanism is now in use in several greenhouse cap-and-trade programs in North America.  Dr. Murray has been invited as a co-author of several national and international assessments of natural resources, especially related to energy and climate change. Of particular note, he serves on a National Academy of Sciences panel on greenhouse gases and the tax code, where he led the panel’s efforts on biofuel subsidies.  He was a convening lead author of the Intergovernmental Panel on Climate Change’s Special Report on Land Use, Land Use Change, and Forestry. He has convened several forums of economic modeling experts to examine and communicate the results of their climate, energy and land use policy efforts to the public and private sectors.  His research has examined the economic effects of traditional command-based regulatory strategies for pollution control and more market-oriented approaches such as cap-and-trade programs and emission taxes.  He has been a consultant to a wide range of clientele in the public and private sector, including numerous federal government agencies, members of Congress and their staff, state regulatory agencies, CEOs and senior staff from Fortune 500 companies, trade groups, nongovernmental organizations, and other academic institutions.   He has authored or co-authored over 100 publications in books, edited volumes, and professional journals across a range od disciplines.  From 2017-21 he was a regular contributor to Forbes. Prior to coming to the Nicholas Institute in 2006, Dr. Murray was Director of the Center for Regulatory Economics and Policy Research at RTI International, a university-affiliated not-for-profit research institution.
