5 good practices to improve the energy efficiency of your industrial sites

- 15 June 2017

Combining both a financial matter and an essential environmental issue, energy efficiency is nowadays a major concern for every industrial sector. Following this idea, it has become essential for each and every company to seek a better energy efficiency as well as an energy transition strategy.


1- Need to evaluate your consumption to control it

First of all, a company needs to evaluate and measure its consumption in order to improve its energy efficiency. Consequently, it will be able to identify the possible improvements, alongside with following its consumption and spot potential disparities. For example, it is strongly advised to have a yearly audit of the energy consumption of a building (heating, ventilation, lighting, lifts, and so on).

2- Seek continuous improvement

In 2017, benefiting from the current period of constant research and innovation, it is more than ever possible to keep on improving. In the energy efficiency context, it can be the case through replacing the most energy-consumer machines (it should actually be done every 3 to 4 years) or optimising processes.

3- Manage the "heat" resource

Heat is a highly significant power source, especially in the nuclear plants or the metal industries. However, huge amounts of heat are spread in the atmosphere whereas they could be reutilised. Indeed, when it is useless at one point of the production line, it can be transferred to another where it will be reutilised (examples: heat in industrial ovens, industrial engines, etc.)

4- Develop industrial ecology

In addition to dealing with their own energy consumption, companies from the same industrial sector can also cooperate. To do so, they can for example exchange information and good practices, transfer energy to one another or use other company's waste as fuel. In a geographical point of view, the optimisation of energy efficiency can be implemented at the scale of a region or an industrial area, which enables thinking as an ecosystem and going over the company itself.

5- Adopt the energy management

The Energy Management Systems (EMS) enable reducing the energy consumption and the costs coming along with it. These management tools insure the setting of good practices, in an efficient and sustainable way. Moreover, it is even advised to delegate those missions to a specialised company through energy performance contracts.


Reliability and continuity of supply, rationalisation of processes, improvement in energy efficiency, and sustainability of installations are central to the solutions developed by ENGIE Ineo for industrial facilities.

For example, ENGIE Ineo signed a Contract of Energy Performance with the city of Cannes (06), focusing on the realisation, the maintenance in global management of the public lighting facilities and the city showcase from 2013 to 2019. Savings are estimated to reach 50% during this period.
