From Jan. 1, 2019 to Jan. 1, 2020
ENEDIS is the main distribution system operator in France (95% of continental France, 36 million customers).
The electricity market requires that production and consumption be assigned to an upstream-downstream balance operator, each electricity provider having at least one. These balance operators guarantee that supply and demand are balanced every half-hour 24/7.
In order to assign energy, Enedis computes the electricity consumption balance every week for each balance operator. Part of the balancing computation involves some consumption or production modelling for several groups of customers (aka profiles).
Since July 1st 2018, we started using “dynamic” profiles in this process, computed with measured energy. These dynamic profiles bring additional precision but can only be calculated ex-post.
Being able to forecast these values is very important since:
They would bring robustness to our process.
Energy planning is of utmost importance to balance operators, who have to guarantee energy supply beforehand and are held responsible for any unbalance in their portfolio.
We would like to forecast 7 dynamic profile time-series, modelling the consumption shape of several mass-market customer groups (residential and small businesses with subscribed power up to 36 kVA) thanks to meteorological and calendar data, as well as any other real time dataset potentially correlated with consumption patterns. Those profiles are coefficients (without units) for each half-hour in the dataset.
The dataset size depends on each specific profile (collected from Oct 13th, 2013 onwards for residential profiles and from Nov 1st, 2016 for commercial profiles). This challenge is about forecasting dynamic profiles values from their past values and all the components of Enedis’ Half hourly Electrical Balancing.
The Testing period will be in the past, from July 1st, 2017 to June 30th, 2018.
There are many possible explanatory variables since consumption patterns are linked to consumers’ behavior and economic activity. Weather conditions (cold spell / heat wave) and business holidays will impact energy consumption but some other factors may also contribute to modifying energy consumption.
As an example, our RES1 profile is presented there, over a week period:
In green: static series including business holidays. In blue: static series including business holidays and weather. In red: dynamic series computed ex-post.

Please be careful to the temporal alignment:
For the same ID, there is a one day delay between data provided in the input files (that are measured or estimated for the date given in Horodate_UTC ) and the values of dynamic Profiles provided in the output files (representing customer behaviour for the date given in horodate).
This delay allows to have a challenge closer to our operational needs: we will be able to get the data from the input files of the previous day to forecast the dynamic profiles.
Data in the time series are hour beginning: for example, a value at à 08h00 is the integrated value from 08h00 to 08h30 for the said data.
Training files include data for the period [13/10/2013 - 12/10/2018] excluding the [01/07/2017 - 30/06/2018] period.
Regarding the 3 commercial profiles, data only start on Nov 1st,2016.
Testing files include data for the [01/07/2017 - 30/06/2018] period.
Please note that we use the French date and time notation: dd/mm/YYYY HH:MM in the files.
