Technological challenges

The Nuclear and Oil & Gas industries are preparing their technological transformations and changes: study of new models for the EPR reactor (EPR NM), diversification for new energies, development of synergies with automotive and telecommunications industries. At the same time, environmental management industries continue to export their expertise outside France.



The challenges that the nuclear industry will have to take up in coming years will require a large proportion of engineering: dismantling of ageing nuclear plants, a market estimated at €220 billion, and the renewal of nuclear plants. EDF is currently studying the EPR NM (New Model) that will cost half as much to build and is planning to build some 40 plants in France as from 2030.


Renewable energies

The share of renewable energies continues to increase and is attracting new players. According to the World Energy Outlook annual report of the International Energy Agency, “nearly 60% of all new power generation capacity in 2040 in our main scenario comes from renewables”. But the intermittent nature of these energy sources will require rapid deployment of communicating sensors and digital management systems, the global market of which is estimated at €30 billion in 2016.


Oil & Gas

With the drop in crude oil prices, the Oil & Gas sector has drastically cut back on investments, cancelling or postponing some projects. However, the International Energy Agency (IEA) has declared that this lack of investment cannot last. Since oil demand will continue to increase by approximately 0.4% per year between 2014 and 2040, it is imperative for the sector to reinvest to balance supply and demand.


Environmental Management

This sector, which combines water management, recycling and waste management activities, is asserting its importance: population growth and urban expansion have led to increasingly large quantities of waste and drinking water shortage.

Energy Energy efficiency of buildings

The quest for energy efficiency consists in providing more effective solutions to optimise energy consumption across the entire value chain, including buildings, which alone account for 40% of energy consumption in France


Maintenance and Upkeep A response to the longer service life of energy farms and plants

While the commissioning and operation of energy facilities represent a considerable investment, the idea of lengthening their service life is more relevant than ever.


Innovation Smart Grids: developing an “intelligent network”

Confronted with a changing energy landscape and the emergence of new environmental issues, the grid needs to be redesigned for operators and consumers to be more proactive in the way they use energy.


Oil & Gas How do we respond to the new market challenges?

State-of-the-art technologies have led to the discovery of huge oil and gas fields. Often located in extreme environments, they require complex extraction and operational infrastructures.
