One-of-a-kind expertise

Measure, analyse and plan ahead: Expertise supporting smart electricity


Power transmission system performance and flows are measured on a permanent basis. This invaluable data is then aggregated, modelled and analysed by our experts so that the right decisions can be taken at the time when action has to be taken to ensure smooth running on a daily basis. It also means that reliable analysis can be carried out to build tomorrow's grid. Our statistical and prospective know-how is recognised by the electricity sector participants. This information is provided to everybody in completely transparent conditions.

Measure in real time

We have developed advanced remote measuring tools which take the pulse of the grid 24 hours a day so that we can determine the amount of electricity generated and consumed in homes at any time. The details per generation sector (fossil fuel, hydropower, nuclear power, wind power, etc) are also available. The electricity traded with the six neighbouring countries can thus be visualised in real time. 

With tangible benefits, such as the capacity to detect and promptly adjust any electricity supply-demand imbalance and measure the share of power generated with renewable energies and trends, this information is essential to build the smart grid.

Manage and analyse data

We have developed cutting edge tools and expertise to use the data derived from grid operation. Numerous participants need to acquire relevant information on electricity system developments. In order to satisfy this need, RTE publishes monthly electricity overviews and annual electricity reports (available in French) which throw light on consumption, trends in renewable energies, trades and grid development projects.

Dynamic simulations are also carried out. What about a concrete example? Electricity consumption over the coming years is assessed based on a data repository which incorporates information on consumption observed. Then the different factors that affect this consumption are varied: demographic trends, economic prospects, climate changes, new uses of electrical equipment, regulations governing energy efficiency, etc.

These analyses are accessible to everybody and constitute a tool for transparency whose purpose is to fuel public debate on energy. For example, the RTE 2014 Generation adequacy report arrived just at the right time to throw light on parliamentary debate on the draft energy transition law for green growth. It especially points out deterioration in security of electricity supply in France for the winters of 2015 to 2018 and proposes solutions to resolve the situation.

Sharing data and analysis with our partners

In order to establish the most reliable models possible, we work very closely with numerous partners. This is the case for Méteo France: the climate data repository that we have jointly set up enables us to assess the impact of cold snaps and heatwaves on the European electricity system.

More and more information is exchanged with the other transmission system operators in Europe so that we can establish hypotheses on generation capacity and consumption for every country which are indispensable for our long-term forecasts. The electricity system participants in France also send us their operating data which is treated with the strictest confidentiality.

Anticipate to act

Substantiated forecasts are compiled to guide our choices on all the timescales:

  • In the short term: precise generation and consumption forecasts are compiled the day before for the next day or the same day. They help us to operate the grid in a reactive and efficient manner.
  • In the medium-term: projections are compiled to anticipate the risks of supply-demand imbalance on the grid. For example, two seasonal analyses (available in French) are published every year (summer and winter). A thorough analysis of electricity supply-demand balance is published every year covering 5 years.
  • In the long term: different electricity generation and consumption scenarios are explored up to the year 2030 in our forecast assessment.

These medium- and long-term hypotheses enable us to define how the grid should be developed over the coming years: a crucial asset for the investments required and lead times for implementation. These developments are presented in our ten year network development plan.
