Notes & Sources

-- = No data reported.
*  = Value is less than half of the smallest unit of measure (e.g., for values with no decimals, the smallest unit is 1 then values less than 0.5 are shown as *.)
NA = Not available.
NM = Not meaningful due to large relative standard error or excessive percentage change.
W = Withheld to avoid disclosure of individual company data.
Note: Small differences between source data and values displayed here may be due to independent rounding.
Note: Components of "Utility-scale net electricity generation (share of total)" may not add to 100% because "Total utility-scale net electricity generation" includes net generation from petroleum coke, pumped storage hydroelectric, other gases, and other energy sources, which are not shown separately.
Note: Territory data may be estimates based on EIA's Short-Term Energy Outlook.
