State Participation in Resource Adequacy Decisions in Multistate Regional Transmission Organizations
The fight over which resources power the grid and how much is required has intensified as flattening electricity demand, low natural gas prices, and preferences for non-emitting technologies push less efficient power plants to retire. The focus has been on substantive solutions, and most recently on attempting to “accommodate” state energy policies in the regional electricity markets—with disappointing results to states, consumer advocates, and clean energy businesses. Missing from this debate is process reform.
Energy efficiency may be an inexpensive way to meet future demand and reduce greenhouse gas emissions, yet little work has been attempted to estimate annual energy efficiency supply functions for electricity planning. The main advantage of using a supply function is that energy efficiency adoption can change as demand changes. Models such as Duke University’s Dynamic Integrated Economy/Energy/Emissions Model (DIEM) have had to rely on simplistic or fixed estimates of future energy efficiency from the literature rather than on estimates from energy efficiency supply curves. This paper attempts to develop a realistic energy efficiency supply curve and to improve on the current energy efficiency modeling.
The Federal Energy Regulatory Commission (FERC) is an independent agency regulating the interstate transport of energy. As innovations and changing consumer preferences reshape the energy industry, FERC must grapple with key issues. This policy brief summarizes pending issues before FERC, including grid resilience, market reforms that would affect newer technologies and non-emitting resources, and transmission and gas pipeline infrastructure build. How FERC decides on these issues would impact consumer costs, determine which resources would receive revenues from FERC-regulated markets, help shape infrastructure investments, and affect the costs of decarbonization policies.
The Federal Energy Regulatory Commission, which regulates wholesale capacity markets, is looking to reconcile market design with state, and potentially federal, policy preferences. In an effort to mitigate this apparent tension in the gas- and coal-heavy Mid-Atlantic and Midwest, the Federal Energy Regulatory Commission proposed a framework on June 29 for carving out those policy-sponsored resources from PJM's capacity market. The June order poses many questions and leaves open many details for stakeholders to resolve ahead of the close of FERC’s initial round of public comments on October 2, 2018. This policy brief offers recommendations to improve the efficiency of the developing proposals and help those responding to the FERC order understand the implications of different design choices related to the Federal Energy Regulatory Commission's proposal.
Effects of Technology Assumptions on US Power Sector Capacity, Generation and Emissions Projections: Results from the EMF 32 Model Intercomparison Project
This article is one of two syntheses in a special issue in the journal Energy Economics on the EMF 32 study, a major modeling study of the electric power sector’s emissions in various policy intervention scenarios. This article focuses on the effects of technology and market assumptions with projections out to 2050. A total of 15 models contributed projections based on a set of standardized scenarios. The scenarios include a range of assumptions about the price of natural gas, costs of end-use energy efficiency, retirements of nuclear power, the cost of renewable electricity, and overall electricity demand. The range of models and scenarios represent similarities and differences across a broad spectrum of analytical methods.
The EMF 32 Study on Technology and Climate Policy Strategies for Greenhouse Gas Reductions in the U.S. Electric Power Sector: An Overview
This introduction to a special issue of Energy Economics presents the key findings of Energy Modeling Forum Model Inter-comparison Project Number 32 (EMF 32) entitled “The EMF 32 Study on Technology and Climate Policy Strategies for Greenhouse Gas Reductions in the U.S. Electric Power Sector.” This study focused on the development and cross-model comparison of results from U.S. climate policy intervention scenarios focusing on policy strategies for achieving greenhouse gas emission reductions in the electric power sector and the sensitivity of emissions and economic results to changes in technology and market assumptions. This overview article describes the motivation for the EMF 32 study, identifies the models used in the study, describes the study's scope and design, and reviews insights in the special issue's articles. A related article focuses on the effects of technology and market assumptions with projections out to 2050.
The expansion of carbon markets in China, Japan, and the Republic of Korea have laid the foundation for discussions on potential carbon market cooperation within Northeast Asia, and the role of the private sector is vital for achieving success in this space, according to a new Asia Society Policy Institute and KPMG Samjong report. The authors present how carbon market linkage within China, Japan, and Korea could take place in unison with industry preferences.
This analysis published in the journal Energy Economics examines how changes in market trends and technology costs are likely to affect electricity generation in the United States in the context of possible future carbon taxes. It uses the Dynamic Integrated Economy/Energy/Emissions Model (DIEM) electricity-sector model to examine a wide range of sensitivity cases for technology and fuel costs under different economic conditions. The model finds that carbon taxes can be an effective way to quickly lower emissions. Shifts among natural gas and renewable generation can vary significantly, depending on capital and operating costs.
Regional electricity markets—operated by regional transmission organizations (RTOs)—span multiple states and bring significant benefits to the electricity grid. States policies—such as renewable or clean energy portfolio standards or procurement mandates—have always helped shape market outcomes, but increasingly they are aimed at addressing perceived market shortcomings. Recent state policy actions to support new or existing resources in RTO markets have renewed attention to issues of RTO market design, including how RTO markets and state policies interact. Those actions, a rapidly changing electricity sector, and low electricity and capacity prices have heightened the urgency of calls for changes in market designs to address perceived inequities, such as market designs that fail to value certain environmental or reliability attributes. This primer is aimed at policy makers and stakeholders who seek an understanding of regional electricity markets and the effect of state policies on those markets as well as an understanding of recent market design proposals that are designed to address the RTO-state policies interaction.
