cap.gen.joined: Joined Electrical Capacity and Generation Output
In JGCRI/electricity_hindcasting_data: U.S.A. Electricity Hindcasting Data

Description Usage Format Details

This is the dataset that reports capacity and generation using the constructed fuel and technological categorical variables, which describe the data more broadly than the native fuel and primemover codes.

1	data(cap.gen.joined)

A data framewith 121104 and 7 variables

These two datasets are joined by two methods. First, in 2001-2002, we join by yr, plntcode, and fuel. We do this because the Generation dataset reports primemovers exclusively as NA for these years. In all other years, we join by yr, plntcode, primemove, and fuel. Neither method uses utilcode, as there are significant inconsistencies within both the Generation and Capacity datasets, which prevent adequate joining between the two datasets.

We take the inner_join() between these datasets using the keys indicated above. Finally, that join is mapped to the overnightcategory and fuel variables contained in our mapping file. Mapping to these new keys requires aggregation, as multiple pm-f codes map to the same overnightcategory and fuel pair. The resulting dataset is used in the calculation of capacity factor.

yr: Year of reported data
startyr: Weighted average (by capacity) of reported start years
plntcode: EIA-assigned plant code
overnightcategory: Technology category
fuel.general: Fuel category
capacity: Reported nameplate capacity, MW
generation: Reported net electrical output, MWh
