title: Offshore wind power production in the North Sea

description: Offshore wind is considered to be a main source of clean energy, providing
 up to half of global electricity needs, and there are large plans for the
 scale-up of offshore wind. However, despite the plans for scale-up, there
 are large disparities in estimates of power potentials. One reason for
 this disparity is too simplified treatments of wind wakes. A thorough
 understanding of energy budgets within wind farms is needed to improve the
 estimates of power potential and energy usage. In this respect, actual
 data on power generation in existing wind farms are highly valuable. This
 dataset contains half-hourly data on power production in 31 wind farms in
 the North Sea for the years 2020 to 2024. The data is used to analyze the
 energy budget of wind farms in the North Sea (see
 https://doi.org/10.1371/journal.pone.0321528). The data is downloaded from
 the Elexon BMRS data marked "Actual Generation Output Per Generation
 Unit (B1610)", but is free to copy, publish, adapt, distribute, and
 transmit.
description: The data is downloaded from the Elexon BMRS API. The data gives
 the actual metered volume output (MWh) per half hour. The name of the csv
 files gives the name of the wind farm that produced the power. The csv
 files contain date and time in the first column and power production in
 MWh in the second column. The time in the first column gives the end time
 of the half-hour over which the power production is
 accumulated.  Downloading data from Elexon for a
 specific wind farm requires that you download data from the bmUnits that
 belong to this wind farm.  Power production given by the bmUnits is summed
 up to get the power production of the wind farm. The data in the csv file
 for a wind farm is the sum of the bmUnit that belong to this wind farm.
 The bmUnits for the wind farms in this dataset is as follows:
