U.S. natural gas dry production, consumption, and gross exports

Source: U.S. Energy Information Administration, Natural Gas Annual 2019

The U.S. Energy Information Administration’s (EIA) Natural Gas Annual shows that the United States set new records in natural gas production, consumption, and gross exports in 2019. In 2019, dry natural gas production increased by 10%, reaching a record-high average of 93.1 billion cubic feet per day (Bcf/d). U.S. natural gas consumption increased by 3%, led by greater use of natural gas in the electric power sector. Natural gas gross exports increased 29% to 12.8 Bcf/d.

Increased use of natural gas by the electric power sector drove U.S. natural gas consumption growth. The electric power sector consumed 7% more natural gas in 2019 than in 2018. Electric power sector consumption grew largely because of favorable natural gas prices and ongoing coal plant retirements. Natural gas consumption in all other sectors were relatively unchanged.

As U.S. natural gas production increased, the volume of natural gas exports—both through pipelines and as liquefied natural gas (LNG)—increased for the fifth consecutive year to an annual average of 12.8 Bcf/d. U.S. LNG exports accounted for most of this increase.

The United States continued to export more natural gas than it imported in 2019, and net natural gas exports averaged 5.2 Bcf/d. In 2019, the United States also exported more natural gas by pipeline than it imported for the first time since at least 1985 (the earliest year in EIA’s natural gas pipeline trade data), mainly because of increased pipeline capacity to send natural gas to Canada and Mexico.

In 2019, dry natural gas production increased by 10%, or 8.7 Bcf/d, reaching a record high of 93.1 Bcf/d for the year. This increase was the second-largest volumetric increase since at least 1930 and second only to last year’s increase.

The two largest natural gas-producing states, Texas and Pennsylvania, also had the two largest increases in natural gas production in 2019. Texas annual average dry natural gas production increased 15%, from 19.3 Bcf/d in 2018 to 22.2 Bcf/d in 2019. Pennsylvania’s natural gas production increased 10%, from 16.9 Bcf/d in 2018 to 18.6 Bcf/d in 2019. Wyoming natural gas production decreased 11%, from 4.3 Bcf/d in 2018 to 3.9 Bcf/d in 2019. This decrease was the largest year-on-year decline of any state in 2019.

Natural gas generators make up largest share of U.S. electricity generation capacity

Based on the U.S. Energy Information Administration's (EIA) annual survey of electric generators, natural gas-fired generators accounted for 43% of operating U.S. electricity generating capacity in 2019. These natural gas-fired generators provided 39% of electricity generation in 2019, more than any other source. Most of the natural gas-fired capacity added in recent decades uses combined-cycle technology, which surpassed coal-fired generators in 2018 to become the technology with the most electricity generating capacity in the United States.

Technological improvements have led to improved efficiency of natural gas generators since the mid-1980s, when combined-cycle plants began replacing older, less efficient steam turbines. For steam turbines, boilers combust fuel to generate steam that drives a turbine to generate electricity. Combustion turbines use a fuel-air mixture to spin a gas turbine. Combined-cycle units, as their name implies, combine these technologies: a fuel-air mixture spins gas turbines to generate electricity, and the excess heat from the gas turbine is used to generate steam for a steam turbine that generates additional electricity.

Combined-cycle generators generally operate for extended periods; combustion turbines and steam turbines are typically only used at times of peak load. Relatively few steam turbines have been installed since the late 1970s, and many steam turbines have been retired in recent years.

Not only are combined-cycle systems more efficient than steam or combustion turbines alone, the combined-cycle systems installed more recently are more efficient than the combined-cycle units installed more than a decade ago. These changes in efficiency have reduced the amount of natural gas needed to produce the same amount of electricity. Combined-cycle generators consume 80% of the natural gas used to generate electric power but provide 85% of total natural gas-fired electricity.

Every U.S. state, except Vermont and Hawaii, has at least one utility-scale natural gas electric power plant. Texas, Florida, and California—the three states with the most electricity consumption in 2019—each have more than 35 gigawatts of natural gas-fired capacity. In many states, the majority of this capacity is combined-cycle technology, but 44% of New York’s natural gas capacity is steam turbines and 67% of Illinois’s natural gas capacity is combustion turbines.

EIA’s International Energy Outlook analyzes electricity markets in India, Africa, and Asia

Countries that are not members of the Organization for Economic Cooperation and Development (OECD) in Asia, including China and India, and in Africa are home to more than two-thirds of the world population. These regions accounted for 44% of primary energy consumed by the electric sector in 2019, and the U.S. Energy Information Administration (EIA) projected they will reach 56% by 2050 in the Reference case in the International Energy Outlook 2019 (IEO2019). Changes in these economies significantly affect global energy markets.

Today, EIA is releasing its International Energy Outlook 2020 (IEO2020), which analyzes generating technology, fuel price, and infrastructure uncertainty in the electricity markets of Africa, Asia, and India. A related webcast presentation will begin this morning at 9:00 a.m. Eastern Time from the Center for Strategic and International Studies.

IEO2020 focuses on the electricity sector, which consumes a growing share of the world’s primary energy. The makeup of the electricity sector is changing rapidly. The use of cost-efficient wind and solar technologies is increasing, and, in many regions of the world, use of lower-cost liquefied natural gas is also increasing. In IEO2019, EIA projected renewables to rise from about 20% of total energy consumed for electricity generation in 2010 to the largest single energy source by 2050.

The following are some key findings of IEO2020:

  • As energy use grows in Asia, some cases indicate more than 50% of electricity could be generated from renewables by 2050.
    IEO2020 features cases that consider differing natural gas prices and renewable energy capital costs in Asia, showing how these costs could shift the fuel mix for generating electricity in the region either further toward fossil fuels or toward renewables.
  • Africa could meet its electricity growth needs in different ways depending on whether development comes as an expansion of the central grid or as off-grid systems.
    Falling costs for solar photovoltaic installations and increased use of off-grid distribution systems have opened up technology options for the development of electricity infrastructure in Africa. Africa’s power generation mix could shift away from current coal-fired and natural gas-fired technologies used in the existing central grid toward off-grid resources, including extensive use of non-hydroelectric renewable generation sources.
  • Transmission infrastructure affects options available to change the future fuel mix for electricity generation in India.
    IEO2020 cases demonstrate the ways that electricity grid interconnections influence fuel choices for electricity generation in India. In cases where India relies more on a unified grid that can transmit electricity across regions, the share of renewables significantly increases and the share of coal decreases between 2019 and 2050. More limited movement of electricity favors existing in-region generation, which is mostly fossil fuels.

IEO2020 builds on the Reference case presented in IEO2019. The models, economic assumptions, and input oil prices from the IEO2019 Reference case largely remained unchanged, but EIA adjusted specific elements or assumptions to explore areas of uncertainty such as the rapid growth of renewable energy.

Because IEO2020 is based on the IEO2019 modeling platform and because it focuses on long-term electricity market dynamics, it does not include the impacts of COVID-19 and related mitigation efforts. The Annual Energy Outlook 2021 (AEO2021) and IEO2021 will both feature analyses of the impact of COVID-19 mitigation efforts on energy markets.

Global liquid fuels production outages have increased in 2020

Disruptions to crude oil and condensate production from members of the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC countries have risen considerably since last year. These outages have contributed to reduced liquid fuel supply and, along with crude oil production declines agreed to among OPEC and partner countries (OPEC+), have contributed to global liquid fuels inventory draws since June.

So far in 2020, monthly oil supply disruptions have averaged 4.6 million barrels per day (b/d) and reached 5.2 million b/d in June, the highest monthly levels since at least 2011, when the U.S. Energy Information Administration (EIA) began tracking monthly liquids production outages. Global oil supply disruptions averaged 3.1 million b/d in 2019, and rising outages in Iran have been the main drivers of the year-on-year increase. EIA does not include field closures for economic reasons or oil demand declines in its accounting of supply disruptions.

Libya, Venezuela, and Iran (the OPEC countries exempt from the latest OPEC+ agreement) were the main contributors to these outages. Domestic political instability in Libya has removed about 1.2 million b/d from oil production since February 2020. The Libyan National Army, the warring faction in eastern Libya, blockaded five of the country’s oil export terminals and shut in oil production from major fields in the southwestern region in January 2020, causing Libya’s production to fall to less than 100,000 b/d by April.

U.S. sanctions have led to production outages in Venezuela and Iran. U.S. sanctions placed on oil-trading companies and shipping companies that facilitated exports of Venezuela’s crude oil in the first half of 2020 removed 500,000 b/d of crude oil production from global markets by August. Ongoing U.S. sanctions on Iran’s crude oil and condensate exports have kept Iran’s disruption levels elevated through 2020, and disruptions there have increased by another 100,000 b/d since January.

Non-OPEC oil supply disruptions, mostly from the United States and Canada, rose to nearly 800,000 b/d in August. Disruptions in Canada occurred when operators ordered nonessential staff to stop work because of coronavirus outbreaks at production sites. In the United States, hurricane-related disruptions and unplanned maintenance affected oil production this summer. Other non-OPEC countries experienced temporary field closures for various reasons such as coronavirus outbreaks among workers, logistical issues moving workers or equipment during the pandemic, fires at field operations in Canada, or other natural disasters.

EIA publishes historical unplanned production outage estimates in its Short-Term Energy Outlook (STEO). In its estimates of outages, EIA differentiates among declines in production resulting from unplanned production outages, permanent losses of production capacity, and voluntary production cutbacks. EIA’s estimates of unplanned production outages are calculated as the difference between estimated effective production capacity (the level of supply that could be available within one year) and estimated production.
