15. Coherence and comparability

Top

15.1. Comparability - geographical

Not requested for this data collection

15.1.1. Asymmetry for mirror flow statistics - coefficient

Not requested for this metadata collection.

15.2. Comparability - over time

See explanation below

15.2.1. Length of comparable time series

We strive to have comparable time series in the energy statistics. Some data series are revised and some are interpolated to connect.

15.3. Coherence - cross domain

See description below

15.3.1. Coherence - sub annual and annual statistics

Due to updated data and more information at later stage subannual and annual statistics may differ more or less.

15.3.2. Coherence - National Accounts

See manuals for fuels on IEA website.

15.4. Coherence - internal

Internal consistency checks are made and efforts to consistency between other statistics are also made.

16. Cost and Burden

Top

Statistics are collected in several institutions in Denmark, so a total of cost and burden is very difficult to estimate.

The Danish Energy Agency have approximately 4-6 full time equivalents.

Costs were approximately 1.5 mill. for 2020.

Energy has a great focus and requires new statistics. Hence, burden increases.

17. Data revision

Top

17.1. Data revision - policy

Survey of energy consumption for manufacturing companies - http://www.dst.dk/en/OmDS/strategi-og-kvalitet/revisionspolitik.

General energy statistics: 2 years prior to reference year is revised in case of updates in data collections.

If substantial new data for a fuel or a flow is collected a revision is implemented when ressources are available.

17.2. Data revision - practice

Fire wood survey - The survey is made every second year. Years with no survey an estimate is made by consultants. Otherwise no revisions are made.

Wood pellet survey - The survey is made every second year. Years with no survey an estimate is made by consultants and main operators in the market. Otherwise no revisions are made.

Survey of energy consumption for manufacturing companies - The survey is made every second or third year. No revisions in this survey.

Monthly oil survey - On monthly basis revisions are made. In annual statistics no revisions are made.

Oil end use survey - No revision

Annual electricity and heat survey (delivering to grid) - Two years back the energy producers may update their input

Annual electricity end use survey - No revision

Biannual survey on heat pumps - Revised after new regulation was implemented (amendment to 2009/28)

Annual production and consumption of biogas outside the transformation sector (and autoproducers delivering to grid) - No revisions

Monthly crude oil - No revision

Consumption of electricity by usage in residential sector: ElModelBolig: The survey is made every second year. Years with no survey an estimate is made by consultants. Otherwise no revisions is made.”

Crude oil imports by field of production - No revision
