Electricitymap-contrib: NO "Uknown" origin assumption
Carbon intensity here is probably to high. Assuming coal is just simply wrong.
If this is data from district heating, which I bet it is, then...
50% is "recycled heat"(92% waste burning, 6% heat waste from industry)
22% from bio (40% wood chips, 29% unspecified solid biofuels)
13% electrical boilers
10% is ambient heat (heatpump(electric) ~28%, sewage ~26% and seawater ~25%)
5% oil/gas

Good point!
Here is what the IEA statistics say for Norway 2016:
Production from: | GWh | Share
-- | -- | --
coal | 146 | 0,098%
oil | 30 | 0,020%
gas | 2600 | 1,738%
biofuels | 41 | 0,027%
waste | 395 | 0,264%
nuclear | 0 | 0,000%
hydro | 144005 | 96,241%
geothermal | 0 | 0,000%
solar PV | 0 | 0,000%
solar thermal | 0 | 0,000%
wind | 2116 | 1,414%
tide | 0 | 0,000%
other sources | 297 | 0,198%
Total production | 149630 | 100,000%
We're talking about a share of the "unknown" category of ~0,6% in total production according to that data. Not sure how significant this is over the year.
Now in winter, it may be a bit more relevant than in the other seasons, though. In "Central Norway" the share of "unknown" in consumption was 7-8% tonight, but the carbon emissions of it made up 50-60% of total emissions of that zone at that time.
A calculated intensity for Norway's "unknown" based on IEA consists of 16% coal (820g/kWh), 3.3% oil (650g/kWh), 48% biomass (230g/kWh)and 33% "others" (still 700 g/kWh).
This makes a weighted carbon intensity of 492g/kWh. This will lower the influence of the "unknown" category a bit.

We do not use coal for anything in mainland so no idea where IEA is getting that from. Maybe the coal plants in Barentsburg and Longyearbyen on Svalbard.
The IEA numbers are not even close to matching the 2016 numbers from the website I linked.

have some interesting tables. I think table 3 and 4 is probably what is relevant here.

Got a callback from someone at Statnett that explained a bit. The other category from ENTSOE is mostly hydro from small plants <10MW. Rest is district heating.
They do not have the system and capacity currently to deal with all of the mini and micro plants. Currently there are 1288 hydro plants at <10MW capacity.
Total capacity of all small plants under 10MW was just over 2702MW as of 7. January 2019

In general I would suggest encouraging organizations to publish data as accurate as possible, because this scales much better than Electricity Map manually tracking down breakdowns for every region around the world.
Currently it is 20:00 in Oslo and the only region with significant "unknown" production is NO3 at 235 MW / 6%. This has grown from 43 MW 24 hours prior. Perhaps I'm misunderstanding Norwegian heating, but "unknown" in ENTSOE was to be substantially district heating, I would expect it to be more significant in areas with more population, particularly more than the reported 65 MW (1%) in NO1 / Oslo area.
If we want to tweak anything, figuring out NO3 is probably best bet. Perhaps a relevant authority could publish a breakdown of what goes into ENTSOE's "unknown" specifically for NO3.

They want to get it more detailed, but it takes time, resources and money. They are not required to provide more details to ENTSOE so that is probably why it is not a priority.
Statnett and all the other power companies responsible for the regional power lines have to spend billions of NOK over the next decade to upgrade and/or replace old lines.
Norway had a lot of expansion going on after WW2 so many lines are reaching their technical life end.

Hi - has anyone been able to get more detailed data here?
Looking at the past 24 hours (weekend), "unknown" has been basically totally not there for all of Norway's zones - again suggesting it is not district heating, as it is 3-4 degrees Celsius in Oslo.

I contacted both Statnett and ENTSOE. Got reply from ENTSOE and was told they would look into it and fix any errors.

Great, let's watch it over next couple of days and see if there is still any significant "unknown" generation reported.

Looks like the unknown values have disappeared now. Anyone able to look back in time and see how long? I do not have "pro".
