Electricite de France said that it plans to invest a whopping $9.93 billion in electricity storage by 2035. “Electricity-storage technologies have a potential to radically change the energy sector,” said Chief Executive Jean-Bernard Levy.

The French utility company said on Tuesday that the planned investment would be used to develop an estimated 10 gigawatts of additional energy storage projects, or roughly twice the total amount of capacity it currently operates, according to Forbes.

The utility said it would target energy storage projects in the European market, especially in France, but that it would also pursue opportunities in Africa, including battery storage and storage plus solar projects in Ghana and the Ivory Coast.

Over the next two years, EDF said it would use roughly one third of its investment in energy storage to acquiring projects and start-up companies focused on energy storage projects and grid applications. A portion of the investment – about $87 million – will also be used to support research and development activities in the energy storage space.

EDF owns a large fleet of nuclear reactors in France, which derives about 75% of its electricity from nuclear energy. France has 58 nuclear reactors operated by EDF, with a total capacity of 63.1 gigawatts.

EDF owns and operates the Gravelines Nuclear Power Plant in northern France, which has an installed net capacity of 5,460 MW and a gross capacity of 5,706 MW, currently ranks as the sixth largest nuclear power facility in the world. The French utility also owns the sixth and seventh largest nuclear power plants in the world, according to Power Technology.

In 2017, EDF and Areva established a joint venture called Edvance Engineering to design and build nuclear islands and control systems for new reactors globally. The joint venture is intended to enhance the export offering of the French nuclear industry by creating what EDF calls an “integrated generator/supplier model.”
