finnishgrid

The goal of finnishgrid is to provide an easy one-liner access to all Fingrid Open Data API functions.

Installation

You can install the development version of finnishgrid from GitHub with:

# install.packages("devtools")
# required dependencies httr and jsonlite
# install.packages(c("httr", "jsonlite"))
devtools::install_github("virmar/finnishgrid")

Free API registration

Optional: add API key as your environment variable (~/.Renviron)

Example

Let's get Finnish hourly electricity consumption and production time-series data for basic visualization.

library(finnishgrid)
start_time = "2021-01-01T00:00:00+0200"
end_time = "2021-01-03T00:00:00+0200"
user_key = NA  # TODO: replace with right key or use .Renviron file

Fetching data with helper functions

elec_cons <- electricity_consumption_FI_RTD(start_time = start_time, 
                                            end_time = end_time, 
                                            user_key = user_key)

elec_prod <- electricity_production_FI_RTD(start_time = start_time, 
                                           end_time = end_time, 
                                           user_key = user_key)

min_elec_cons <- min(elec_cons$value)  # consumption
max_elec_cons <- max(elec_cons$value)

min_elec_prod <- min(elec_prod$value)  # production
max_elec_prod <- max(elec_prod$value)

y_max <- max(max_elec_cons, max_elec_prod)
y_min <- min(min_elec_cons, min_elec_prod)

Basic data visualization

plot(elec_cons$start_time, elec_cons$value, type = 'l',
     col = "green", ylim = c(y_min, y_max),
     ylab = "Produced/Consumed (MW)",
     xlab = "Time", main = "Electricity")
lines(elec_prod$start_time, elec_prod$value, type = 'l', col = "blue")
legend("topright", c("Cons", "Prod"), fill = c("green", "blue"))

Get electricity consumption in Finland with get_data() function
