In December and January, the power demand is mostly affected by holidays around religious celebrations. We have recently updated our assumptions on the holiday effect for all areas for the upcoming Christmas and New Year feasts and have put together some statistics and facts you might find useful.
Highest Total and Relative Impact
The combined effect during the Christmas days (between 23rd and 26th of December) is around 144 GWh/h for this year. During the New Year celebrations (1st and 2nd of January 2018), we expect the consumption reduction by an average of 90 GWh/h around Europe. The lower effect for the New Year days can be explained by the fact that 2nd of January is not a public holiday in most countries, but we observe the so-called “bridging-effect” for this day in several countries.
The highest absolute reduction of consumption due to the Holiday Effect can be observed in Germany, where from Small Christmas Eve until the second Christmas day around 833 GWh less electricity will be consumed in total. This number contributes to an average of 34.7 GWh/h and 12.3% of normal German consumption during this period. Germany is followed by this evaluation by Italy and France, with a total reduction of 632 GWh, respectively 444 GWh for the same period.
The picture changes somehow when looking on the holiday effect for the first days in January, as the highest reduction in power demand can be observed for Italy (around 723 GWh) where the 6thof January is also a public holiday. This holiday is celebrated in some countries around Europe and we observe a bridging effect for several days between the 1st and the 6th of January.
Macedonia and Serbia celebrate Christmas later compared to the rest of Europe, on 7 January. These countries follow the Russian Orthodox tradition, which uses the old Julian calendar for religious celebrations. There is a 13 days difference between the two calendars, and thus the date for the Christmas day is shifted and does not coincide with the Catholic celebration.
