Energy Management in Industry: The Complete Guide
In a context of price volatility and strict environmental regulations, energy management has become a major strategic lever for industrial competitiveness.
Optimizing energy consumption can reduce costs by 10 to 30%, ensure regulatory compliance, and strengthen credibility with customers and partners.
This comprehensive guide presents the challenges, priority areas to optimize, and solutions for implementing effective energy management in your company.
Energy management in industry is not just about reducing a bill. It's a structured approach that combines economic competitiveness, regulatory compliance, and process control. This article analyzes the 4 major challenges, identifies the 5 most energy-intensive processes, and presents how a platform like Wattnow enables achieving 10-30% savings while complying with ISO 50001 standards and regulatory framework.
Why has energy management become a strategic issue?
Energy management addresses four major challenges that directly impact the performance and sustainability of industrial companies.
Competitiveness lever
Facing energy price volatility, controlling consumption helps stabilize production costs and protect margins. Savings achieved can be reinvested in innovation.
Regulatory compliance
Mandatory energy audit, GHG assessment, tertiary decree, BACS decree: requirements are multiplying. Good energy management facilitates compliance and avoids penalties.
Process control
Quick leak detection, optimization of settings, preventive maintenance: energy monitoring helps avoid invisible overconsumption and improve installation reliability.
Credibility and image
Customers and contractors value companies committed to energy performance. It's a competitive advantage in tenders and a mark of environmental responsibility.
The 5 most energy-intensive processes in industry
To optimize effectively, you need to know where consumption is concentrated. These 5 processes typically represent 70 to 80% of an industrial site's energy bill.
Steam production
Used for heating, cooking, drying, or heat treatment, steam is very energy-intensive. Losses related to insulation, purges, or the network can generate significant overconsumption.
Compressed air
Essential for operating machines, compressed air is very costly to produce. Leaks (which can represent 20-30% of production) and improper settings are major sources of waste.
Industrial refrigeration
Essential in agri-food, chemicals, or pharmaceuticals. Its performance depends heavily on settings, sizing, heat exchanger maintenance, and operating conditions.
Electric motors
Pumps, fans, and drive systems represent a significant portion of electricity consumption. Their efficiency depends on performance, load level, and use of variable speed drives.
Thermal processes
Furnaces, dryers, heated baths: these equipment consume large amounts of energy. Optimization involves reducing losses, improving insulation, and heat recovery.

Managing energy in industry: what obligations?
Industrial sites must comply with several regulatory requirements related to energy management. Here are the main ones:
| Obligation | Applicability | Frequency | Objective |
|---|---|---|---|
| Energy audit | Large enterprises | 4 years | Identify energy savings potential |
| GHG assessment (BEGES) | >500 employees (mainland) >250 employees (overseas) |
3 years | Quantity and reduce greenhouse gas emissions |
| Tertiary decree | Tertiary areas > 1000 m² | Targets for 2030, 2040, 2050 | Progressive reduction of consumption |
| BACS decree (2025) | Tertiary buildings with heating/cooling > 70 kW | Equipment obligation | Automation and control of systems |
| ISO 50001 standard | Voluntary | 3-year certification, annual audits | Energy management system |
Since 2025, the BACS decree requires for tertiary buildings equipped with heating or cooling systems of more than 70 kW the installation of automation and control devices. In an industrial site, this obligation only concerns tertiary areas. These systems facilitate consumption monitoring, setpoint adjustment, and waste detection.
How to optimize energy management in industry?
Sustainable improvement requires combining a clear strategy, targeted actions, and appropriate monitoring tools.
Define a strategy
Set measurable objectives, establish a roadmap, designate responsible persons, and rely on ISO 50001 standard to structure your energy management system.
Take action on the ground
Improve settings, implement preventive maintenance, install variable speed drives, optimize insulation, and recover waste heat.
Equip with monitoring tools
Deploy sensors, meters, supervision systems, and dashboards to monitor consumption in real-time and manage performance.
Implement continuous improvement
Regularly analyze data, adjust actions, train teams, and value progress made.
How to finance better energy management?
Numerous schemes exist to support investments in energy efficiency and reduce return on investment time.
Energy Savings Certificates (CEE)
Bonus paid in exchange for energy savings achieved. Industries can benefit from specific CEE bonuses to finance their energy efficiency projects.
Energy Performance Contract (CPE)
A provider finances the work and is remunerated based on a share of the savings generated. Performance risk is borne by the provider.
Other aids and financing
"Green industry" tax credit, Heat Fund (ADEME), Bpifrance loans, exceptional depreciation, springboard for ecological transition of companies.
Our team supports you in preparing financing applications (including CEE) to optimize the profitability of your energy efficiency projects. We identify with you the most suitable schemes for your situation.
