An R data package with the UK National Grid historical demand for electricity between 2011 and 2018


The UKgrid dataset is an example of a multiple seasonality time series. This time series captures the demand for electricity and its components in the UK since 2011 using half-hour intervals. In addition, the package provides a function to extract, subset and aggregate the series into ts, xts, zoo, data.frame, data.table, or tbl.

The data was sourced from the National Grid UK website

# install.packages("devtools")



# Load the full dataset (data.frame format)

# Extract only the demand field (ND - Net Demand) using xts format
extract_grid(type = "xts", 
             columns = "ND") 

# Extract the demand between 2016 and 2017 using tbl format
extract_grid(type = "tbl", 
             columns = "ND", 
             start = 2016, 
             end = 2017)

# Extract the first 10 days in 2018 and aggregate to hourly using zoo format
extract_grid(type = "zoo", 
             columns = "ND", 
             start = as.Date("2018-01-01"), 
             end = as.Date("2018-01-10"),
             aggregate = "hourly")
