Tracking and understanding regional data: power consumption, power generation and inter-regional power flows

For each of France’s regions, view the history of power consumption, power generation per energy source and the balance of power flows between regions.

Regional data at your fingertips

For each region, you can view:

  • power consumption and output: forecast, real-time consumption and historical records
  • the generation mix as well as each sector’s capacity factor and coverage rates: fossil-fuelled, hydro, nuclear, solar, wind, pumped-storage
  • the balance of incoming and outgoing power flows

A model of mainland France’s regional power output (excluding Corsica) is also available.

  1. Regional consumption:
    This is determined on the basis of information about each region’s output and inter-regional flows.
  2. Regional generation mix:
    Indicators pertaining to the regional generation mix simulate the output of all the region’s generation facilities, whether they are connected to the transmission system or to power distribution networks.
    These various indicators are established in real time by using grid measurements and in addition, by using estimates based on models developed by RTE.
  3. Coverage rate:
    A generation sector’s coverage rate within a region is the proportion of this sector within the region’s consumption.
  4. Capacity factor:
    A generation sector’s capacity factor is the amount of power it generates against the sector’s operational installed capacity.
  5. Inter-regional power flows:
    The balance of inter-regional power flows is established on the basis of transmission data remotely monitored on the lines of the public transmission system. This data is supplemented by an estimate of flows on networks downstream of the public transmission system, based on information provided by distribution companies (Enedis and local distribution companies). RTE has developed algorithms for estimating inter-regional flows on distribution networks for which the company does not have a remote-monitoring system.

Browsing through the calendar and the regional data graphs

The calendar enables you to view data over a period of one day or more (up to 8 weeks on desktop and 1 week on a smartphone).

Historical data is updated twice following initial publication:

  • In the course of the following month, historical data is consolidated ("consolidated data" in green in the calendar, based on available metering data).
  • In the course of the first half of the following year, historical data is finalised ("final data" in red in the calendar, based on all metering data).

"DC" and "ND" abbreviations

  • The abbreviation "DC" that appears for some generation technologies in some regions means "confidential data". Bound by legislation governing statistical confidentiality, RTE is not able to publish this information.
  • "ND" (in French) means "not available", i.e. the data does not exist for the requested period.

Spotlight on the comparative regional histogram

At a glance, view mainland France’s 12 regions and compare their power consumption, their output per energy source and their operational generation fleet.

Spotlight on the tool enabling you to view power flows between regions

For each region, this diagram shows you the balance of imported/exported power flows with other regions or neighbouring countries.

A region is connected to its neighbours by power lines carrying power flows that can be imported or exported. This diagram shows the balance of imported/exported power flows between neighbouring regions: place the cursor on an exchange between two regions to see the import/export balance. The "size" of the exchange extremities indicates the power being transmitted between a region and its neighbour.

If the extremity on the side of region A is bigger than that on the side of region B, this means that region A exports more power than it imports on its exchange lines with region B.
