List of european power plants, data sources for electricity generation

Filed under: Carbon Trading, Data Insights, Energy, Open Source — howardchong @ 6:19 pm

I was looking for a list of power plants in Europe in 2008. I didn’t find one. You know why? It just got created in late 2008, and I just found it in 2009.

More beta below the bump.

Beta, AKA additional info

Carma is not specifically pitched as a list of power plants in Europe, but it covers Europe well. It is aimed at covering the world. You can download the data.

It has firm names or company names associated with each firm, as well as CO2 emissions, and generation in MWH.

It is not THAT well linked to companies, because some companies have subsidiaries. So, make sure you collect everything with the text “RWE” as an RWE company. I’ve done some linking, so if you want to compare, please shoot me a line and we can share.

You got to be careful of a few things. First, understand that much of Europe uses Combined Heat and Power (AKA cogeneration) and district heating. So, in this case, your tonsCO2/MWH might be high, but this may be due to the CHP. Second, Carma also covers a large amount of auto-generation and might cover refining and heat. For example, International Paper has a plant in Europe. I would guess this is a plant they run to supply their own electricity. Third (and this only matters if you’re charcterizing firms), I believe that many large firms have large partially owned subsidiaries. For example, consider ENBW. It is 45% owned by EDF and 45% owned by a german firm, according to Wikipedia:

The two principal shareholders of EnBW are Électricité de France (EDF), with a 45% share and Oberschwäbischen Elektrizitätswerke (OEW), with a 45% share. In accordance with a closed consortium agreement between EdF and OEW, EdF will take over the supervision over EnBW until 2012. Furthermore, the two shareholders agreed to keep the share ratios as they are and to vote in mutual agreement on important decisions.

Other Data Sources

I’m not sure what their data source is, but I bet that they aggregated info from individual national information. For Europe, Eurostat does NOT have this information (to my knowledge), though Eurostat does report MWH and Carbon on a national basis, I think annually. IEA (International Energy Agency) has the same level of info as Eurostat.

The obvious issue with the Eurostat data is that it aggregates all the power plants in a country. Also a big issue (but not as obvious) is that it is somewhat easy to measure carbon for a country by tracking flows of fuels, but attribution to sectors (electricity, for example) may be problematic. At best, it’s a black box and we have to trust that it was done right.

Carbon from electricity is tracked very well by the CITL (Community Independent Transaction Log) of the European ETS (Emissions Trading Scheme). But this doesn’t report MWH.

Another potential source of info is EPER. But this is emissions only.

In the US, we have the CEMS system, which is continuous emission monitoring system. Data includes heat rate and power output at a high resolution (daily? hourly? I forget). Data is gov’t, so it is public. One problem is that carbon isn’t measured. Not such a big deal, since you can calculate it stoichiometrically from the input fuel information, at least in theory.
