Electricity Balance

Data represents the overall balance of consumption, production, import and export of electricity in an area. Production is divided into main production types.

Gross consumption = sum of production + sum of exchange to connected areas. A positive exchange is import of electricity, while a negative is export. The total production is the sum of all production types. Transmission losses is Gross consumption - net consumption. Electric boilers consumption is included in gross and net consumption.

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 08:00Z. 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 08:00. 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. 2017-07-14T08:00Z.

Description

A date and time (interval), shown in UTC time zone, where the values are valid. 00:00 o\u2019clock is the first hour of a given day interval 00:00 - 00:59 and 01:00 covers the second hour (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.

Central production

Comment

Danish electricity supply was historically based on large, central coal, oil or gas fired steam power plants or CHP plants located on coasts or fjords. Most of these central plants also have outlets for district heating supply to nearby major cities. Central power plants are defined in BEK nr 565 af 02/06/2014, Section 17: It includes power plants, where the capacity is above 100 MW, or placed in one of the following locations:

  1. Amagerv\u00e6rket.
  2. Asn\u00e6sv\u00e6rket.
  3. Aved\u00f8rev\u00e6rket.
