The eia package provides API access to data from the US Energy Information Administration (EIA).

Pulling data from the US Energy Information Administration (EIA) API requires a registered API key. A key can be obtained at no cost here. A valid email and agreement to the API Terms of Service is required to obtain a key.

eia includes functions for searching EIA API data categories and importing time series and geoset time series datasets. Datasets returned by these functions are provided in a tidy format or alternatively in more raw form. It also offers helper functions for working with EIA API date strings and time formats and for inspecting different summaries of series metadata. The package also provides control over API key storage and caching of API request results.

Installation

Install the CRAN release of eia with

install.packages("eia")

To install the development version from GitHub use

# install.packages("remotes")
remotes::install_github("ropensci/eia")

Example

To begin, store your API key. You can place it somewhere like your .Renviron file and never have to do anything with the key when you use the package. You can set it with eia_set_key in your R session. You can always pass it explicitly to the key argument of a function.

library(eia)

# not run
eia_set_key("yourkey") # set API key if not already set globally

Load a time series of net electricity generation.

id <- "ELEC.GEN.ALL-AK-99.A"
