First automated battery storage system

27 July 2021


On 2 July, RTE, the French public electricity transmission system operator, together with its partner Nidec Industrial Solutions, inaugurated RTE's first experimental site for the automated management of large-scale electricity storage. Located in Vingeanne - Jalancourt, in the Côte-d'Or department, the project, designated ‘Ringo’, is the world's first such experiment and will test the automatic management of surplus renewable electricity.  

In favourable weather conditions local solar or wind energy production can greatly increase and exceed the transport capacity of the national electricity grid, resulting in the dispersion of the energy produced. The Ringo system makes it possible to store surplus renewable energy during peaks in production and return it to the grid as and when needed.  

It is also a smart system. In fact, for the first time anywhere, a storage battery site will be remote-controlled using robots that collect data in real time, representing the first automatic control on a national energy grid. Thanks to sensors installed on the grid that constantly measure electricity flows, algorithms able to optimise storage in real time can be created.

The Vingeanne - Jalancourt site, located in a region of high wind energy production, was chosen as the location for one of the experimental batteries which has a storage capacity of 12 MW/24 MWh. Work commenced in January 2020, and now the system has been put into service, and is scheduled to run for 3 years.

The Ringo project meets the renewable energy development goals set by the French government and aims to make the electricity transmission grid more flexible by 2030 and to integrate, in particular, large-scale electricity storage solutions. This storage experiment has been approved by the French CRE (Commission de Régulation de l'Energie - Energy Regulatory Commission) for a total investment of € 80 million.
