Archive EPA eGrid

[cmgosnell]

Motivation and context:

Briefly describe the dataset. What is it, and why do we want to archive it regularly?
Include a link to the dataset webpage and any metadata documentation.

• Most recent version
• Historical versions
• Metadata

The links to all of the files show up on these two pages above, but the urls where the data is actually stored all seem to follow this pattern:

https://www.epa.gov/system/files/documents/{year of publication}-{month}/egrid{data year}{file name}

Note that the publication date is different than the data year. The data year is what we want to reference when we archive this data.

Also note that there are several files per year. We want to grab all of them so you'll need to use add_to_archive.

Requirements for archiving

To be archived on Zenodo, a dataset must be:

• published under an open license that permits reuse and redistribution
• less than 50Gb in size (when zipped)
• relevant to energy modelling and research

Checklist for archive creation
