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 August 2015). Uploaded 24/09/15.

Corrections in production data can occur from time to time, as data are continually being consolidated.

In May and June 2015 the Register has been updated for wind turbines  25 kW, resulting in a large increase in the number of these turbines in the database. Master data for some of these turbines may be incomplete.

As of July 2015 the Master Data Register’s data regarding the turbines’ XY-coordinates has been spliced with coordinate-data derived from a database of the Danish Geodata Agency’s (DGA). The coordinates from the DGA are complemented with coordinates from the Master Data Register. The origin of each coordinate-set is stated 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. Firstly,  in order to enable correct settling of governmental support for electricity generation based on renewables (especially concerning the original output full-load hour assessment), and secondly, in order to make the register robust to future changes in e.g. settling rules and any consequent need for additional data and control.

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.
