Default France beat its own electricity consumption yesterday

Because of the cold temperature all over the country, the electricity consumption has been beaten in France yesterday and today, respectively : 90.200 megawatts (MW) at 7PM and 91,500 MW at 7PM. The previous record was 17 December 2007 with 89,480 MW at 6:58PM.

RTE, the society managing the very high and high voltage lines declared having anticipated the event. They asked their bigger clients with whom they have a special agreement to limit their consumption. They also bought by anticipation on different markets.

Currently in France 56 of the 58 nuclear plants and most of hydro plants are active. Tomorrow the temperature will continue to go down all over the country (night at -5 to -8C in hotter regions/23 to 17F) but Wednesdays' consumptions are lower than Mondays and Tuesdays. Even if they anticipated, they asked 2 specific geographical region to lower their consumption today to avoid supply problems.

My consumptions for last 2 days (kWh) with nobody at home from 9AM to 6:30PM :

daynight (off peak hours)day (peak hours)

Note : off peak is from 10:30PM to 6:30AM.
To be compared to last week min/average/max of 9/13/16 (night) + 22/29.4/35 (day) with someone at home all day long.
Happily since Sunday we are using one ceiling fan in the living room and when nobody was at home which we didn't used last week.

Most interesting information :
  • They said that a lowering of 1C of the external temperature increases the electricity needs in France (63 millions inhabitants) by 2,100 MW, which corresponds to twice the consumption of Marseilles (826,000 inhabitants).
  • They also said that lowering the internal temperature by 1C decreases the bill by 7%.


Earth absorbs 1.8 t CO2/head/yr, while a French generates 6.2 t CO2/yr

Based upon "official" French figures...
