definition of renewable electricity needs to be fixed

[cjlaumans]

Renewable electricity definition is according to the CBS the renewable electricity production divided by the electricity use. This needs to be fixed in the query renewable_electricity_share which currently divides by electricity production.

Waiting for reply from WM and MdH before changing this myself.

[cjlaumans]

Ok, this is going to be the new query:

DIVIDE( SUM(V( G(electricity_production); output_of_electricity * sustainability_share)), SUM(V( INTERSECTION(G(final_demand_electricity),USE(energetic)); demand)) )

Anyone care to comment?

It is the sustainable produced electricity divided by the final demand of electricity. The final demand is composed of electricity used in: Agriculture, Households, Industry, Other, Transport, Buildings, and Energy Production.

The query gives a value of 9.2% for the NL start scenario.

This is I think in line with the definition giving that Alex found in the CBS publication:

"De Nederlandse overheid had voor het jaar 2010 een doelstelling voor hernieuwbare elektriciteit. Het streven was dat 9 procent van het elektriciteitsverbruik afkomstig zou moeten zijn uit hernieuwbare bronnen."

The EU-richtlijn doesn't have any specific clause explaining the calculation of renewable electricity.

The EU regulation, which we want to follow as much as possible, differs from Dutch one in that they use GROSS electricity production. We will use gross production in this calculation as well, correct? That is what I would prefer.

@markquintel and @wmeyers pls comment.

[cjlaumans]

Yes, the EU uses gross final consumption of energy. Their definition is as follows:

The share of energy from renewable sources shall be calculated as the gross final consumption of energy from renewable sources divided by the gross final consumption of energy from all energy sources, expressed as a percentage

‘gross final consumption of energy’ means the energy commodities delivered for energy purposes to industry, transport, households, services including public services, agriculture, forestry and fisheries, including the consumption of electricity and heat by the energy branch for electricity and heat production and including losses of electricity and heat in distribution and transmission;

They do not elaborate on electricity however and therefore the query I wrote above is more according to the Dutch standard.

[wmeyers]

But the EU directive does give information on how to calculate with renewable electricity. For example, the output of a wind turbine or solar panel is taken as the demand 1-on-1. As far as I can interpret it right now that is also what you are doing in the query. So that would be according to EU specification.

[wmeyers]

CBS reports both the EU definition and their own one.

The CBS defition is harder to model, because it uses reference technologies per type of use to determine how 'renewable' it is.

If the Dutch definition is different from the EU definition, then I would suggest to make use of the flexible dashboard, and have both definitions available.

I don't know what the current Dutch definition is (I think they are changing towards the European one). The difference between the European definition and the current ETM is the transmission losses.

I prefer EU definition, fuck the CBS definition. Good to understand, but if they give EU definition, then why use theirs?

[markquintel]

I would suggest not to go down this 'reference technology' path, difficult to understand and difficult to model in our ETM. Hence: use European definition

[wmeyers]

I agree!

[AlexanderWirtz]

Exactly

Ok, the query is as I wrote it above, I'm closing this issue.

[markquintel]

If the definition or 'renewable share' has changed in the ETM, the wiki descriptions should be adapted accordingly:

http://wiki.quintel.nl/index.php/Renewables http://wiki.quintel.nl/index.php/Dashboard#Renewables

[cjlaumans]

Renewable share definition has not changed, at least not by me. This discussion was concerning the renewable electricity share.

[cjlaumans]

Ok, nevermind. I will update the definitions, because now with the new one it is possible to get to 100%+ since we're dividing electricity production by demand without a correction for export. This isn't wrong, just simply a matter of definitions. Just import that our ETM users know that as well!

[cjlaumans]

I've added a short description of the renewable energies calculation to: http://wiki.quintel.nl/index.php/Renewables#Dashboard_calculation

[markquintel]

To be complete I added a small comment: 'It does include energy sector own use (= consumption in the conversion sector) as this is currently included in the industry sector in the ETM.'
