Summary of Natural Gas Monthly (June 2018)

Core Content

The Natural Gas Monthly (NGM) report provides monthly and annual data on natural gas supply, consumption, prices, and storage for the United States, covering the period from 2013 to 2018. It is published by the U.S. Energy Information Administration (EIA), an independent agency under the U.S. Department of Energy (DOE). The report includes data on production, consumption, imports, exports, and storage, as well as price information for various sectors. All data are reported at a pressure base of 14.73 psia and a temperature of 60°F, with cubic feet converted to cubic meters using a factor of 0.02831685.

Main Points

• Data Collection: The EIA gathers data through surveys and reports from various sources, including state and federal agencies, and provides detailed information on the data sources in Appendix B.
• Geographic Coverage: The report covers all 50 U.S. states and the District of Columbia.
• Data Types:
  • Gross Withdrawals: Total natural gas extracted from wells.
  • Marketed Production: Natural gas that is sold to consumers.
  • NGPL (Natural Gas Plant Liquids) Production: Natural gas liquids produced from gas processing plants.
  • Net Imports: Natural gas imported into the U.S.
  • Net Storage Withdrawals: Natural gas withdrawn from underground storage.
  • Consumption: Natural gas used across different sectors.
• Consumption Breakdown:
  • Lease and Plant Fuel Use: Fuel used at gas processing plants and on leased lands.
  • Pipeline and Distribution Use: Natural gas used in pipelines and distribution systems.
  • Deliveries to Consumers: Natural gas delivered to residential, commercial, industrial, and electric power sectors.
• Price Information:
  • Citygate Price: The price at which natural gas is delivered to the first point of delivery.
  • Consumer Prices: Prices at which natural gas is sold to different consumer sectors.
  • Heating Value: The energy content of natural gas, measured in British thermal units (Btu) per cubic foot.

Key Information

• Table 1: Summary of natural gas supply and disposition in the U.S. from 2013 to 2018. It includes Gross Withdrawals, Marketed Production, NGPL Production, Dry Gas Production, Supplemental Gaseous Fuels, Net Imports, Net Storage Withdrawals, Balancing Item, and Consumption.
• Table 2: Natural gas consumption by sector (residential, commercial, industrial, electric power) and includes Lease and Plant Fuel Use, Pipeline and Distribution Use, and Total Consumption.
• Table 3: Selected national average natural gas prices, including NGPL Composite Spot Price, Natural Gas Spot Price, Citygate Price, and Consumer Prices for residential, commercial, industrial, and electric power sectors.
• Data Sources:
  • Form EIA-914: Monthly Crude Oil and Lease Condensate, and Natural Gas Production Report.
  • Form EIA-857: Monthly Report of Natural Gas Purchases and Deliveries to Consumers.
  • Form EIA-191: Monthly Underground Gas Storage Report.
  • Form EIA-923: Power Plant Operations Report.
• Estimation and Revision:
  • Some data are estimated or revised based on historical trends and annual reports.
  • Data for 2013 through 2015 are considered final, while data for 2016 and later are preliminary.
• Underground Storage:
  • Data for January 2017 and onwards include only underground storage, excluding liquefied natural gas (LNG) storage.
  • Net Withdrawals and Activities of Storage Operators are reported by state.
• Special Notes:
  • The Balancing Item represents data imbalances and losses.
  • Line Loss is included in pipeline and distribution use, defined as gas lost due to leaks, damage, accidents, migration, and blow down.
  • Revised data and Estimated data are marked accordingly.
  • Independent rounding may cause discrepancies in totals.
