Read basic API specification at https://data.fingrid.fi/en/instructions and register a free user account.

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

FINGRID_OPENDATA_API_KEY=MY_SECRET_KEY_FROM_API_PAGES

Setting time range with UTC, and API user key

start_time_utc = "2024-06-01T00:00:00.000Z"
end_time_utc = "2024-06-03T00:00:00.000Z"
user_key = NA  # TODO: replace with right key or use .Renviron file

Fetching data with helper functions

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

elec_cons <- powersys_electricity_consumption_FI_RTD(start_time_utc = start_time_utc,
                                            end_time_utc = end_time_utc,
                                            user_key = user_key)
Sys.sleep(1)

elec_prod <- powersys_electricity_production_FI_RTD(start_time_utc = start_time_utc,
                                           end_time_utc = end_time_utc,
                                           user_key = user_key)
Sys.sleep(1)

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",
     sub = "Data source Fingrid / data.fingrid.fi, license CC 4.0 BY")
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
