EIA’s long-term projections show that most of the electricity generating capacity additions installed in the United States through 2050 will be natural gas combined-cycle and solar photovoltaic (PV). Onshore wind looks to be competitive in only a few regions before the legislated phase-out of the production tax credit (PTC), but it becomes competitive later in the projection period as demand increases and the cost for installing wind turbines continues to decline.
For EIA’s Annual Energy Outlook 2019 (AEO2019), EIA calculates two measures that, when used together, provide an intuitive framework for understanding the capacity expansion decisions modeled for utility-scale power plants—those with a capacity rating of 1 megawatt (MW) or greater.
The levelized cost of electricity (LCOE) represents the cost to build and operate a power plant, converted to a level stream of payments over the plant’s assumed financial lifetime. Installed capital costs include construction costs and financing costs. Operating costs include fuel costs (for power plants that consume fuel) and expected maintenance costs. LCOEs may also include other applicable tax credits or subsidies.
The levelized avoided cost of electricity (LACE) accounts for the differences in the grid services each generating technology is providing (a power plant’s value) to the grid. For example, natural gas combined-cycle plants and coal plants provide dispatchable baseload services to the grid and thus have similar LACE values, even if their LCOE values differ. A generator’s avoided cost provides a proxy for the potential revenues from sales of electricity generated. As with LCOE, these revenues are converted to a level stream of payments over the plant’s assumed financial lifetime.
The ratio of these two measures serves as a value-to-cost ratio. Power plants are considered economically attractive when their projected LACE exceeds their projected LCOE, meaning their value-cost ratio exceeds one.
The relative costs and values of several technology options are calculated for each of the 22 electricity regions in the modeling system used to inform EIA’s Annual Energy Outlook. Calculations start in 2021 because that is the first feasible year that all three technologies are available to come online in the model, given the assumed construction lead-time and licensing requirements.

Because both LCOE and LACE are levelized over the lifetime of the plant, these values change over time. Natural gas combined-cycle units’ LCOEs increases gradually as natural gas prices rise. Utility-scale solar photovoltaic (PV) and onshore wind’s LCOEs initially increase as a result of the loss of the tax credits but then decrease because of the continued decline in installed costs. Wind’s LCOE may also increase as the best wind resource sites are built out and new projects must be installed in areas that have either lower wind resources or less ease of access.
Natural gas combined-cycle units are considered, on average, the marginal source of electricity generation through 2050, meaning the cost of electricity generation from this technology is most often the basis of comparison for new power plants. As natural gas prices increase, the marginal source becomes more expensive to operate, and the value to the grid of avoiding this cost by building new capacity increases, as seen in the general upward trend in LACE for natural gas combined-cycle and onshore wind.
Conversely, solar PV’s LACE is generally flat to declining during the projection period. As solar penetration in the grid increases, solar capacity saturates during the midday hours, causing the value of electricity delivered in those hours to decrease.
In the AEO2019 Reference case, natural gas combined-cycle’s value-cost ratio is closest to 1.0 throughout the projection, indicating that its value just covers its costs. Natural gas combined-cycle units account for the largest share of new power plants (43% of the utility-scale total from 2021 through 2050). Solar PV’s value-cost ratio is slightly less than 1.0, indicating that, on average, its value does not cover its costs, but capacity is still added. In some cases, these solar PV additions may be uneconomic, but they still occur to satisfy the renewable portfolio standard (RPS) requirements in 29 states and the District of Columbia.
Onshore wind’s value-cost ratio remains lower than 1.0 throughout the projection period and lower than solar PV. Consequently, little onshore wind is installed in the Reference case, except in the near term when wind capacity is built to take advantage of the available PTC.

U.S. crude oil production in the U.S. Federal Gulf of Mexico (GOM) averaged 1.8 million barrels per day (b/d) in 2018, setting a new annual record. The U.S. Energy Information Administration (EIA) expects oil production in the GOM to set new production records in 2019 and in 2020, even after accounting for shut-ins related to Hurricane Barry in July 2019 and including forecasted adjustments for hurricane-related shut-ins for the remainder of 2019 and for 2020.
Based on EIA’s latest Short-Term Energy Outlook’s (STEO) expected production levels at new and existing fields, annual crude oil production in the GOM will increase to an average of 1.9 million b/d in 2019 and 2.0 million b/d in 2020. However, even with this level of growth, projected GOM crude oil production will account for a smaller share of the U.S. total. EIA expects the GOM to account for 15% of total U.S. crude oil production in 2019 and in 2020, compared with 23% of total U.S. crude oil production in 2011, as onshore production growth continues to outpace offshore production growth.
In 2019, crude oil production in the GOM fell from 1.9 million b/d in June to 1.6 million b/d in July because some production platforms were evacuated in anticipation of Hurricane Barry. This disruption was resolved relatively quickly, and no disruptions caused by Hurricane Barry remain. Although final data are not yet available, EIA estimates GOM crude oil production reached 2.0 million b/d in August 2019.
Producers expect eight new projects to come online in 2019 and four more in 2020. EIA expects these projects to contribute about 44,000 b/d in 2019 and about 190,000 b/d in 2020 as projects ramp up production. Uncertainties in oil markets affect long-term planning and operations in the GOM, and the timelines of future projects may change accordingly.

Because of the amount of time needed to discover and develop large offshore projects, oil production in the GOM is less sensitive to short-term oil price movements than onshore production in the Lower 48 states. In 2015 and early 2016, decreasing profit margins and reduced expectations for a quick oil price recovery prompted many GOM operators to reconsider future exploration spending and to restructure or delay drilling rig contracts, causing average monthly rig counts to decline through 2018.

Crude oil price increases in 2017 and 2018 relative to lows in 2015 and 2016 have not yet had a significant effect on operations in the GOM, but they have the potential to contribute to increasing rig counts and field discoveries in the coming years. Unlike onshore operations, falling rig counts do not affect current production levels, but instead they affect the discovery of future fields and the start-up of new projects.

The API gravity of crude oil input to U.S. refineries has generally increased, or gotten lighter, since 2011 because of changes in domestic production and imports. Regionally, refinery crude slates—or the mix of crude oil grades that a refinery is processing—have become lighter in the East Coast, Gulf Coast, and West Coast regions, and they have become slightly heavier in the Midwest and Rocky Mountain regions.
API gravity is measured as the inverse of the density of a petroleum liquid relative to water. The higher the API gravity, the lower the density of the petroleum liquid, so light oils have high API gravities. Crude oil with an API gravity greater than 38 degrees is generally considered light crude oil; crude oil with an API gravity of 22 degrees or below is considered heavy crude oil.
The crude slate processed in refineries situated along the Gulf Coast—the region with the most refining capacity in the United States—has had the largest increase in API gravity, increasing from an average of 30.0 degrees in 2011 to an average of 32.6 degrees in 2018. The West Coast had the heaviest crude slate in 2018 at 28.2 degrees, and the East Coast had the lightest of the three regions at 34.8 degrees.
Production of increasingly lighter crude oil in the United States has contributed to the overall lightening of the crude oil slate for U.S. refiners. The fastest-growing category of domestic production has been crude oil with an API gravity greater than 40 degrees, according to data in the U.S. Energy Information Administration’s (EIA) Monthly Crude Oil and Natural Gas Production Report.
Since 2015, when EIA began collecting crude oil production data by API gravity, light crude oil production in the Lower 48 states has grown from an annual average of 4.6 million barrels per day (b/d) to 6.4 million b/d in the first seven months of 2019.

When setting crude oil slates, refiners consider logistical constraints and the cost of transportation, as well as their unique refinery configuration. For example, nearly all (more than 99% in 2018) crude oil imports to the Midwest and the Rocky Mountain regions come from Canada because of geographic proximity and existing pipeline and rail infrastructure between these regions.
Crude oil imports from Canada, which consist of mostly heavy crude oil, have increased by 67% since 2011 because of increased Canadian production. Crude oil imports from Canada have accounted for a greater share of refinery inputs in the Midwest and Rocky Mountain regions, leading to heavier refinery crude slates in these regions.
By comparison, crude oil production in Texas tends to be lighter: Texas accounted for half of crude oil production above 40 degrees API in the United States in 2018. The share of domestic crude oil in the Gulf Coast refinery crude oil slate increased from 36% in 2011 to 70% in 2018. As a result, the change in the average API gravity of crude oil processed in refineries in the Gulf Coast region was the largest increase among all regions in the United States during that period.

East Coast refineries have three ways to receive crude oil shipments, depending on which are more economical: by rail from the Midwest, by coastwise-compliant (Jones Act) tankers from the Gulf Coast, or by importing. From 2011 to 2018, the share of imported crude oil in the East Coast region decreased from 95% to 81% as the share of domestic crude oil inputs increased. Conversely, the share of imported crude oil at West Coast refineries increased from 46% in 2011 to 51% in 2018.
