An overview of the collective agreement 3100 salary scale in the electricity and gas industries
The electricity and gas industries, which includes both electricity and gas professionals, is one of France’s strategic industries. Collective agreement 3100 precisely governs job management, position classification, and the salary scale, which will be adjusted in 2025. In conjunction with collective bargaining, this agreement aims to guarantee balanced and fair compensation for all employees. These rules were originally intended to promote stability in a sector undergoing constant technological and economic change.
Over the past several years, the collective agreement 3100 salary scale has undergone adjustments, particularly to address inflation and human resources management requirements in the French context. The latest agreement signed in 2022 marked an important milestone, introducing a 2.3% increase in the ‘national basic wage’ (SNB) to offset the rising cost of living and ensure skill retention.
In this context, Kevin Grillot, a career management specialist in the electrical industry, emphasizes the importance of mastering this scale to effectively support negotiations with unions or in the day-to-day management of human resources. A thorough understanding of the salary scale allows any company in the sector to anticipate its salary costs, establish coherent salary policies, and, above all, ensure compliance with current regulations.

Main changes to the 2025 salary scale for the electricity and gas industries
In 2025, the salary scale for collective agreement 3100 has been significantly adapted to reflect the economic situation and technological advances in the sector. The 2.3% increase in the national basic wage (SNB) last January is the highlight of this change. At €525.68, this new base salary constitutes the minimum base for all classifications.
In addition, the hierarchical coefficients have been adjusted. These coefficients determine the salary scale according to job classification and associated responsibilities. This update has aligned compensation levels with new technological responsibilities, particularly for innovative professions related to renewable energy or smart grids. Here’s a brief overview of the major changes to better understand this evolution:
2.3% increase in the SNB: the amount increased to €525.68 as of January 1, 2023.
- Guaranteed minimum annual increase: €1,040 gross, in addition to the SNB increase.
- Updated hierarchical coefficients: ranked in ascending tones to reflect a more readable gradation adapted to modern responsibilities.
- Introduction of new criteria for certain classifications, particularly in the context of sectors undergoing ecological transition.
- These changes, orchestrated by Kevin Grillot and his colleagues in human resources, are part of a proactive management approach aimed at maintaining the sector’s attractiveness while respecting collective bargaining. The new scale is intended to be more precise, fairer, and, above all, better adapted to the current realities of the electricity and gas labor market.
Element
| Former (2022) | New (2023) | National Basic Salary (NBS) |
|---|---|---|
| €513.86 | €525.68 | Gross Annual Guaranteed Increase |
| N/A | €1,040 | NR 50 Hierarchical Coefficient |
| 244.30 | 250.10 | NR 250 Hierarchical Coefficient |
| 628.30 | 643.90 | Key Elements of the Coefficient Classification in Agreement 3100 |
At the heart of salary management for the electricity and gas industries, the hierarchical coefficient classification is a cornerstone. It allows for the assessment of the responsibilities, required skills, and technical complexity of the position held. The salary scale is therefore largely based on this numerical index, which serves as a benchmark for compensation.
For 2025, this classification will continue to evolve with the in-depth revision of the coefficients. The guiding principle of this update is to make the job hierarchy more transparent and to promote more balanced negotiations between employers and unions. The range starts at a coefficient of 50, corresponding to entry-level technician positions, and goes up to a coefficient of 370, reserved for senior managers or large-scale project managers.
Here is a simplified overview of the new classification:
NR 50 to 75: Qualified technicians and entry-level supervisors.
- NR 80 to 110: Experienced technicians or supervisors.
- NR 115 to 150: Intermediate team leaders.
- NR 155 to 225: Technical managers or section managers.
- NR 230 and above: Senior managers, managers of major projects or production centers.
- The impact of this classification is considerable in career management, allowing each employee to clearly visualize their potential progression based on their skills and seniority. Employers, for their part, see it as a tool to structure their salary policy and negotiate effectively during union meetings.

The wage agreements concluded under Convention 3100 extend to all companies in the electricity and gas industries. The application period generally runs from January 1, 2023, for an indefinite period, unless renewed through indicative negotiations. These terms guarantee stability in human resources management.
Compliance with these agreements requires each company to implement rigorous management practices, including regular updates of salary scales. In the event of non-compliance, the labor inspectorate may intervene, or employees may refer the matter to the industrial tribunal. Transparency in the display of salary scales, particularly on pay slips, remains an essential obligation.
It should also be noted that provisions may provide for exceptional mechanisms, particularly during mass increases or sector-specific adjustments. The minimum increase guarantee clause demonstrates its importance in 2025, in the face of increasingly difficult inflation. By simulating this with a company in the sector, Kevin Grillot demonstrates how these adjustments ensure socioeconomic stability.
Beyond the salary scale, the electricity and gas industries sector offers a range of measures to strengthen employee motivation and retention. The implementation of bonuses, allowances, and health coverage has been strengthened as part of the 2022-2025 collective bargaining negotiations.
For example, the company mutual insurance company must maintain a high level of coverage, particularly within the framework of the National Interprofessional Agreement (ANI). The agreement stipulates that by 2025, minimum coverage covers routine care as well as dental and optical care. The employer’s financial contribution must meet these obligations, failing which sanctions may apply.
Regarding bonuses, specific mechanisms have been established to encourage performance, attendance, and mobility. These include:
Incentive bonuses linked to overall performance.
- Compensation related to on-call or irregular work hours.
- Bonuses for the ecological transition, particularly for jobs related to renewable energy. In summary, these management tools play a fundamental role in aligning human resources with the sector’s economic and ecological strategy. Managing these systems requires a thorough understanding of collective bargaining agreements to avoid any disputes or sanctions in 2025.

In 2025, the national and international economic climate is heightening the stakes. The energy transition, technological innovation, and the desire to retain young talent require all stakeholders to engage in constructive dialogue. These negotiations focus not only on raises, but also on bonus management, continuing education, and the development of specific skills.

Practical steps for calculating and applying the salary scale in 2025
For any company, applying the salary scale in accordance with Convention 3100 requires particular vigilance. The first step is to understand the hierarchical coefficient specific to each employee. This is determined based on position, responsibility, and experience. Once this coefficient has been identified, simply refer to the table updated for 2025, which indicates the corresponding amount. The formula is simple:
Look for the hierarchical coefficient in the grid.
Consider the corresponding value in euros in the ‘New coefficients’ column.
Multiply the base by this coefficient to obtain the gross salary.
- Practical example: a technician classified NR 80, with a coefficient of 279.30, has their gross salary calculated as follows:
- Salary = SNB (€525.68) x coefficient (279.30)
- which gives a result of approximately €146,950 per year, i.e., a gross monthly salary appropriate to the classification.
Outlook and tools for optimal grid management in the electricity sector in 2025
The electricity and gas industry must anticipate changes in human resources management. In 2025, the trend is toward increased digitalization to monitor pay scale compliance in real time, optimize bonus management, and increase transparency for employees. Modern HR platforms such as Payfit, which integrate automatic salary grid management, are becoming essential to avoid errors or disputes. By using these tools, companies can also develop differentiated compensation policies based on skills, performance, or the ecological transition.
With this in mind, Kevin Grillot also recommends developing training for human resources managers so that they have a thorough understanding of legislation, negotiation, and strategic career management in the sector. https://www.youtube.com/watch?v=x2woRzhH4aY
