CO2 Emission

The dataset is an updated near up-to-date history for the CO2 emission from electricity consumed in Denmark measured in g/KWh.

The values for DK1 and DK2 are the same, because both represent the total value of CO2 emissions in Denmark. Ongoing work will later give the correct individual values for the two price areas and the current value (for DK1 and DK2) will be shown under an extra column named DK. The calculations for the CO2 emissions are based on emissions from each power plant above 10MW and where all power plants below 10MW is regarded as one power plant. Furthermore, the calculations are based on production per hour, consumption per hour and exchange per hour. For further information please see the document (in Danish) “Deklarationer af EL”.

Please also note:

  • The resolution of the data is 5 minutes but the up-date frequency is a bit slower, which is 15 minutes.
  • To calculate the emission rate from CO2 the 125% method is used, which means that coproduced heat is produced by a given efficiency by 125%.

5 minutes UTC

Description

A date and time (interval), shown in UTC time zone, where the values are valid. 00:00:00 o\u2019clock is the first 5 minutes of a given day, interval 00:00:00 - 00:04:59, and 00:05:00 covers the second 5 minutes period (interval) of the day and so forth.

Please note: The naming is based on the length of the interval of the finest grain of the resolution

Comment

Please note that the format shown in the example applies to data download as JSON, XML or fetched through the API and is in accordance with the ISO 8601 standard. The format is slightly different when it is shown on screen or downloaded manually as CSV or XLSX. This is mainly due to readability and consideration for Excel users.

In preview (in the GUI) all timestamps are shown as (display convention) YYYY-MM-DD hh:mmZ e.g. 2017-07-14 08:05Z. The Z will remind viewers that this is UTC.

In download (CSV and XLSX) the date time are exported as YYYY-MM-DD hh:mm e.g. 2017-07-14 08:05. That is without the \u201cT\u201d and the \u201cZ\u201d and the seconds. Excel will recognize it as date-time. The user must remember the convention about time zones.

In download (JSON and XML) the full format is used YYYY-MM-DDThh:mmZ e.g. 2017-07-14T08:05Z.

5 minutes DK

Description

A date and time (interval), shown in Danish time zone, where the values are valid. 00:00:00 o\u2019clock is the first 5 minutes of a given day, interval 00:00:00 - 00:04:59, and 00:05:00 covers the second 5 minutes period (interval) of the day and so forth.

Comment

On one normal day there will be 24 * 12 = 288 intervals.

When daylight saving times shifts there will be either 276 or 300 intervals.

Price area

Description

Same as bidding zone. Denmark is divided in two price areas, or bidding zones, divided by the Great Belt. DK1 is west of the Great Belt and DK2 is east of the Great Belt.

Comment

If price area is \u201cDK\u201d, the data covers all Denmark.
