“What cannot be measured does not exist.” This quote from the 1922 Nobel Prize winner for physics Niels Bohr sums up the importance of data today in a digital world. Without collecting energy consumption data, it is impossible to measure and therefore act to improve the energy performance of a building.
But how to find your way: distributor data, supplier data, invoices, index statements… Sobre Energie helps you better understand your energy consumption data.
How to achieve energy sobriety?
Follow our 4 tips:
-
Prefer distributor data to supplier data for analyzing your consumption
Distributor data (ENEDIS, GRDF, SUEZ, etc.) from meter indexes are those which best reflect the operational reality of consumption.
Supplier data from invoices must be used to monitor budgets, not to monitor consumption.
Indeed, supplier data (Dalkia, EDF, ENGIE, TDE, etc.) has an accounting reality, but does not reflect the operational functioning of the building.
- They are made available at different intervals
- They correspond to the invoice for consumption which has been smoothed out & monthly paid in proportion to the number of days indicated in the invoice.
Even if distributors transmit consumption data regularly and frequently and are the most reliable source for the accuracy of the data, they have no commitment to quality of service towards third party users (service providers, customers…).
Therefore, they can sometimes have some data gaps, particularly when smart meters do not respond or when their databases are under maintenance.
Data holes that they correct a posteriori.

Check the ability of your meters to be read remotely
Distributor data is retrieved from meters, also called PCE, RAE, PDL, PRM, etc.
The counters can be
- Remotely readable: they automatically communicate ex-Linky connected meter data for electricity
- Manually readable: the indexes are read and transcribed by a distributor operator, at a variable frequency of up to 6 months. If you are in this case, plan to replace your manual meters with remote reading meters to have faster consumption readings.
The reporting of data in an energy management platform such as DATAMARC is conditional on entering the correct format of the distributor meter number and its connection to the correct site.
How to reduce your energy consumption?
-
Analyze your consumption data with a minimum hindsight of 2 months
In the case of remote readable meters, consumption data is automatically integrated into DATAMARC.
However, distributors can transmit the information at different time steps or on different days. You must therefore wait for a month M, the first day of month M+2, for all the meters to be read remotely.
In the event of an anomaly on the meter, 2 months may pass without measurement transmission.
For example: Enedis considers a meter with a daily time step an anomaly from the moment when for 2 months this meter has not transmitted any measurement.
Non-remotely readable meters are read manually by your distributor at an uncontrolled frequency.
We remind you that the Distributors do not engage with any third party in the transmission of data. They therefore have no obligation to transmit this data and SOBRE cannot be blamed for a lack of data if it has not been transmitted by the distributor.
-
Analyze your supplier invoices per semester or per year only
To date, supplier data (invoices) can only be retrieved from supplier portals .
The collection of data is linked to the issuance of the invoice: which implies a delay between the month of consumption (m) and the provision of information ranging from 1 to 2 months (m+2).
Depending on the supplier subscription level, the data posted on the supplier portal is not always usable. Without a meter number and site reference we cannot use them.
The diversity of suppliers implies a great heterogeneity of the data (unit, format, step, frequency) which does not allow an analysis on a month by month basis but over a period of 6 months or 1 year.
Suppliers often bill estimated consumption which they adjust a posteriori based on actual consumption. This may lead to a modification of the integrated data: increase or decrease in consumption for a period.
Note that for a year N, the completeness of supplier data is estimated around April/May of N+1. So as of February 10, it is possible to have the N-1 consumption trend but without having the definitive scope. This will be possible around May N+1.
Did you know?
- Out of 35,000 municipalities, all have an electricity distributor, the vast majority ENEDIS (92% of municipalities). But there are local electricity distributors: for example Strasbourg electricity networks, GEREDIS, etc.
With the exception of the Strasbourg Electricity Network, a large proportion of Local Distribution Companies do not communicate consumption data in dematerialized and usable format to third parties or customers.
Consequently, we cannot recover this data except through the transmission of indexes by the site operating manager.
- Only 9,800 municipalities benefit from a gas distributor, the main one being GRDF (95% of cases). There are also local gas distributors: for example Soregies, Réseau GDS
