Publication of "Year in Review 2010: Energy Infrastructure Events and Expansions"

August 31, 2011 - 10:43am


The Department of Energy Office of Electricity and Energy Reliability announces the publication of a new report, Year-in-Review: 2010: Energy Infrastructure Events and Expansions

The Year-in-Review provides an overview of the events that occurred in 2010: disruptions and additions to energy infrastructure in the United States as well as international events of importance to U.S. energy supplies. The report is organized like the Energy Assurance Daily.

Energy Assurance Daily

The Energy Assurance Daily (EAD) is a web-based publication of the Infrastructure Security and Energy Restoration (ISER) Division of the Office of Electricity Delivery and Energy Reliability (OE). It summarizes public information about significant changes in:

  • U.S. energy infrastructure
  • Energy flows within and into the United States
  • Oil and gas exploration, production, movement, and demand worldwide

Published daily, excluding Federal holidays, it provides highlights of events in energy systems, flows, and markets rather than a comprehensive coverage of all energy-related issues. It functions as a tool for energy planners, policy makers, and other stakeholders to keep abreast of the constantly changing conditions in the energy sector.

EAD stories are organized into four types: Major Developments; Energy Stories (which are further categorized into sections called Electricity, Petroleum, Natural Gas, and Other); Energy Notes (which are very brief entries); and Energy Prices. Whether an energy event is covered as a Major Development, an Energy Story, or an Energy Note depends on the size of its impact. The specific parameters for categorizing EAD stories are provided in Appendix A. Guidelines and Criteria for EAD Story Selection. Because these parameters are static, the Major Developments are published in the EAD only when a story of national significance occurs. To put the day’s stories into context, each EAD closes with a table of petroleum and natural gas spot prices.

Focus and Limitations of the Report

This Year-in-Review report is the culminating analysis of all of the 2010 issues of the EAD. It is worth noting here that because the EAD is derived entirely from publicly available information, the resulting report is limited in its scope. Classified or business-confidential data are not factored into the analysis, nor is information that is accessible only through subscription services. EAD data collection cannot be considered exhaustive, as public availability depends on regulatory, corporate, or media disclosure. And due to differences in the regulatory regimes across energy types and indeed across different States, certain areas of the energy sector and certain parts of the country report more heavily than others. For example, California and Texas support very thorough energy reporting mechanisms, while some other States do not. The Nuclear Regulatory Commission reports daily on the status of all nuclear plants in the country, but there is no such equivalent in any other generation sector. For that reason, it would be inadvisable to attempt an “apples to apples” comparison of certain elements of the sector, such as outages across States or across generation types. Instead, this report provides a snapshot of newsworthy events and broad trends that shaped the U.S. energy outlook in 2010.
