About CEA

CEA (Commissariat à l’énergie atomique et aux energies alternatives) is a French government-funded technological research and development provider. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world. CEA staff is about 16000 people, annual budget is 4.3 billion Euros, and priority patents filed exceed 650.


The CEA is active in four main areas: low-carbon energies, defense and security, information technologies and health technologies. In each of these fields, the CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research.

The CEA is based in ten research centers in France, each specializing in specific fields.
15,867 technicians, engineers, researchers and staff work at the CEA, for €4.3 billion budget.

GreenDataNet activities

CEA tasks are focused on two directions: first, the management of power supply of data centers at local level, considering prediction of consumption and local availability of renewable energies, and optimized management of the battery; second, the aggregation of a network of data centers into a global demand response system.

Expected benefits

The energy and battery management algorithms further developed during this project are expected to be transferred to and implemented by the industrial partners.

Previous experience

CEA is involved in numerous projects dealing with smart grids, grid-coupled storage, and massive integration of solar energy. These projects are contracts with industry or collaborative projects at national or European levels.
