A full year of hourly capacity factors for one solar and one wind resource
at a single site, for examples that need a realistic sub-annual profile
rather than a synthetic one – storage sizing, curtailment and
storage_duration() in particular.
Format
A data.frame of 8760 rows and three columns:
- slice
timeslice,
"d001_h00"to"d365_h23".- solar
solar capacity factor, 0-1.
- wind
wind capacity factor, 0-1.
Source
Derived from the NASA MERRA-2 reanalysis with the merra2ools
package. See data-raw/vre_cf.R for the generating script.
Details
The site is deliberately unlabelled: the data carries no coordinates, region code or name. It is one plausible pair of contrasting profiles, not a claim about a particular place. Solar is a fixed-tilt profile, wind a 100 m hub height; each comes from a single resource cluster.
slice is already in the d365_h24 vocabulary, so the table joins directly
onto calendars$d365_h24 with no conversion.
