Power generation/Norway

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.

Example:

name=Nore I kraftstasjon

power=plant

plant:source=hydro

plant:output:electricity=214 MW

operator=Statkraft

start_date=1928

Wind farms

Tag one node for each generator as in this example:

power=generator

generator:source=wind

generator:method=wind_turbine

generator:type=horizontal_axis

generator:output:electricity=2.5 MW

Then create a site relation with all generators as members and tag it with power=plant and additional information as in this example:

type=site

power=plant

plant:source=wind

name=Midtfjellet vindpark

plant:output:electricity=110 MW

start_date=2013

Common mistakes

• 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.
