Demand has been stabilising


For several years now, the long-term trend has been toward a stabilisation of total electricity demand, thanks to generally improved demand-side management and despite increased use of electric appliances.

Consumption nonetheless declined slightly year-on-year in 2018, due to temporary factors including generally warmer weather, especially in the very early and late months of the year, as well as less robust economic growth than in 2017 and significant social movements in the rail transport sector in the spring.

Why are adjustments made to gross consumption?

To better identify structural trends

When it is very cold outside, electricity is used for heating. When the weather is very hot, people use power for cooling. To better analyse structural trends from one year to the next, power consumption data is adjusted to strip out “weather effects”.  Once this is done, electricity demand corresponds to what would have been consumed if temperatures had been the same as reference temperatures

.

Adjustments can be made for other factors as well. For instance, February has an extra day in leap years. To strip out this calendar effect, consumption is adjusted in such a way as to count only 365 days.

 

 

Adjusted consumption


To get a clearer picture of structural trends, RTE makes adjustments to account for the impact on demand of weather and the extra day in February in leap years. Adjusted consumption thus reflects what demand would have been at reference temperatures and for a year with 365 days.

Excluding the energy sector from the calculation, consumption adjusted for weather and calendar effects ended 2018 at 474 TWh, broadly in line with the total for 2017 (-0.3%) and the average for the past ten years.

Note: To calculate adjusted consumption, it is necessary to exclude the energy sector because the adoption of a new uranium enrichment process in 2012 severely impacted the sector and caused a steep decline in consumption.
