WikiProject Norway/Norwegian Infrastructure networks
This is a subproject of WikiProject Norway where information about the infrastructure network in Norway is collected. Please help by adding more information.
- Map all electric power distribution (power lines and substations).
- Map all electric power generators (power plants, wind parks...).
- Map all major telecommunication cables, i.e. fiber optic cables connecting Norway to the world.*
- Power lines are mapped with one of two values. power=line is for all lines above 22kV and power=minor_line for 22kV and below.
- Most lines in Norway are AC and will have three cables=*.
- Some lines can have six or more cables=* and will therefore also have multiple circuits=*.
- Never create overlapping ways for each line (circuit), but instead add circuits=* and cables=* values.
- When adding multiple voltage=* values add the separate them with semicolon and order them highest to lowest (example: 100;50;25).
- Norges vassdrags- og energidirektorat (NVE) data will display multiple circuits on same towers as individual lines.
- Lines above 300kV often have multiple wires=* per cable. Most commonly two, but some have three. NVE and power companies often refer to them as "duplex" and "triplex". Some 300kV lines have been built with duplex or triplex and some lower voltage lines have been upgraded to be ready for future voltage increases. Finding this information may require surveying.
- Because of the close proximity of the wires they are prone to collecting more ice and snow during winter. To preempt problems some mountain crossings use a thicker single cable for segments of the power line.
- The most common voltages used in Norway are 11kV, 22kV, 66kV, 132kV, 300kV and 420kV. This may differ between companies.
- NVE will have several different voltage values in their data. It depend on if the reported value is the nominal voltage or the isolation voltage.
- Common isolation values you might see are 145kV for lines operating at 132kV, 72kV for lines at 66kV and 24kV for lines operating at 22kV.
- To make things even more complicated some companies operate at odd voltages for parts of their grid:
- Agder Energi have two regional grids, one 132kV in the east and a 110kV in the west. This is not a tagging mistake.
- Some lines may not operate at 66kV and instead use 60kV or even below 50kV. They just don't have to as the load is not great enough and/or the isolation level is not good enough to use higher voltage.
Example of a power line:
Example of extra tags when two lines share towers:
Power pole vs. power tower
Outline the perimeter of the plant with a closed way. Add power=plant and add all additional relevant tags. Add landuse=industrial to the perimeter unless the plant is underground or limited to a single building. Buildings that are part of the plant are normally tagged building=industrial.
- Many hydro plants in Norway are located inside mountains. Make sure you add location=underground to these.
- name=Nore I kraftstasjon
- plant:output:electricity=214 MW
Tag one node for each generator as in this example:
- generator:output:electricity=2.5 MW
- name=Midtfjellet vindpark
- plant:output:electricity=110 MW
- Adding the total output of a hydro plant to the each individual turbine.
- Each turbine will have its own value that is added to get the total output, so unless there is only one turbine this will be wrong. Finding each turbines specification can require a lot of research as it might not be mentioned on the relevant websites.
- Assuming that all turbines in the plant have the same power output.
- They may have been built at different times or been upgraded and can have different specifications.
Main focus so far has been on lines above 22kV. See here for a map of power in Norway: openinframap.org
Progress as of March 2018:
- Lines above 22kV have been completed in Sogn og Fjordane.
- In Møre og Romsdal lines above 22kV are missing for the northern part as NVE had no voltage data for Nordmøre Energiverk lines. Also missing some 132kV and above north of Sunndalsøra. The rest is almost complete.
- Oppland is completed above 22kV.
- Buskerud completed above 22kV northwest of Hønefoss and Hokksund.
- Telemark is, with the exception of Porsgunn municipality, complete above 22kV.
- Aust-Agder completed above 22kV with the exception of a 132kV line between Bykle and Hovden.
- Vest-Agder done for lines above 22kV east of Feda and Lyngdal substations.
Power plants >10MW have been added in the same areas. Exception for smaller plants is made if they are directly connected to the regional lines.
