Master Data Register of Wind Turbines

The Master Data Register of Wind Turbines is a national database which contains all Danish power producing wind turbines. The Register has information on location, technical specifications and output for each wind turbine.

Data from the Register in Excel format

Data from the Register are available in Excel format. The table contains site and power output data of all wind turbines. The data are organized in two groups: one of operating and one of decommissioned wind turbines.

Data on operating and decommisioned wind turbines (as at end of May 2016). Uploaded 24/06/16.

Unfortunately, data for June are delayed. It is expected that they will be available medio September together with data for July 2016.

Please note that the production data is currently undergoing a major revision, and differences from previously published data may occur. For some individual turbines there are major changes in production data, as compared to the data published in the master data register at the end of December 2015. However, at aggregated levels the changes are minor.

The XY coordinates in the register are a combination of coordinates from both the Danish Geodata Agency (GST) and the original master data. The GST coordinates have been used primarily and supplemented with coordinates from the master data where no coordinates from GST are available. The origins of the coordinates are shown in the table.

At there is, among other things, a map of Denmark's wind turbines.


Regular data updating

TThe Danish Energy Agency (DEA) updates the Register’s data once a month in conformity with data extracts received from the power distribution companies via the Danish transmission system operator,

Reporting to the DEA is due by the 15th of each following month; thus monthly data are available on the DEA’s website with approximately one month’s delay.


Background for the Register

The Master Data Register has been established by the DEA in corporation with and the power distribution companies.

The Register is used for administration, statistics and price control including full-load hour assessment and has been established in accordance with EU Directive 2001/77/EC of 27 September 2001on the promotion of electricity produced from renewable energy sources in the internal electricity market.


Regarding the data

The data forwarded to the DEA by regarding the turbines’ technical specifications and power output is based on reports received from the power distribution companies.

The data are updated regularly and the updates include among other things:

·        New and decommissioned wind turbines

·        Changes in information on operating turbines

·        New and adjusted information on power output

Each record in the register contains information on one specific wind turbine. A group of e.g. 5 wind turbines connected to the same meter must be reported as 5 distinct wind turbines, i.e. 5 separate records in the register. 

It is obligatory for owners to report information on each individual wind turbine.

A precise definition of each column in the register can be seen in the description of contents.


Regarding data quality

The DEA has become aware of the fact that some of the data in the Register is inaccurate and/or incomplete. A quality assurance process has therefore been initiated, aiming at improving data quality.



The DEA, or other data suppliers, shall not be responsible for any errors or delays due to force majeure, including errors or delays due to strikes or lockouts, and neither for direct or indirect losses or consequential damage to the customer or any joint contractors of the customer caused by the said events.
