For energy-intensive industries in Cameroon, reliable power is not simply an operating preference. It can determine whether a mine, metallurgical facility, processing plant or manufacturing operation can run at its intended capacity.
For an industrial developer considering its own generation facility, however, the technical decision is only one part of the equation. The more important question is how that facility fits within Cameroon’s electricity law: what approvals are required, whether a concession is necessary, what happens when generation exceeds the plant’s own demand, and how any additional output can reach the market.
Consider a hypothetical industrial operation, Steel 1, requiring approximately 20 MW of continuous supply. Its engineering team determines that a 30 MW generation facility would provide a more resilient operating margin and allow for maintenance, load variation and future expansion.
The immediate commercial question is straightforward: if Steel 1 consumes 20 MW and the facility can produce 30 MW, what happens to the additional 10 MW?
Cameroon’s legal framework provides a pathway, but it is not a simple private-sale arrangement. The treatment of industrial self-generation, transmission infrastructure and excess output is governed by the Electricity Law and its implementing regulations.
1. The legal foundation for industrial captive generation
The starting point is Law No. 2011/022 of 14 December 2011 governing the electricity sector in Cameroon. ARSEL publishes the law as part of its official legal framework for the sector.
For industrial developers, Articles 46 and 47 are particularly important. Article 46 recognizes the ability of an industrial production company to generate and transmit power between its production and industrial sites and/or interconnection points in order to satisfy its industrial requirements.
The legislation also addresses what happens when the facility produces more than the industrial operator requires. Article 46 links that additional output to Article 57, while also providing that the industrial producer is subject to public-service obligations in relation to the treatment of that output.
Article 47 goes further by distinguishing the industrial producer’s generation activity from any associated transmission activity. Where applicable, each is subject to a distinct production or transmission concession.
This distinction matters. An industrial facility should not be treated simply as a large private generator operating outside the electricity regulatory system. The legal structure anticipates a formal framework for industrial generation and, where relevant, the movement of power beyond the facility.
For the full statutory framework, developers should consult ARSEL’s official publication of the electricity laws.
2. Why the 20 MW requirement does not tell the whole story
Returning to Steel 1, the company’s internal demand is 20 MW, but the proposed facility has a 30 MW capacity.
From an engineering perspective, the additional capacity may be justified. It can provide operating flexibility, accommodate future production growth and reduce the risk of relying on a generator running permanently at its maximum output.
From a legal and commercial perspective, however, the additional 10 MW creates a separate question.
- Can Steel 1 retain the additional output for future industrial expansion?
- Can it place that power onto the national transmission system?
- Can the excess be supplied to another industrial consumer?
- Who determines the applicable commercial terms?
- What role does the transmission network operator play?
- Does the additional output trigger further public-service obligations?
These questions should be answered during project structuring rather than after the generating facility has already been financed and constructed.
3. Industrial generation is structured through a concession framework
One of the most important distinctions for developers is between general self-production rules and the specific framework applicable to industrial generation.
ARSEL’s published sector framework distinguishes between concessions, licences, authorizations and declarations. It expressly identifies the production and transmission of electricity for industrial purposes among activities falling under the concession regime.
This is particularly relevant for a large facility such as Steel 1. A developer should therefore establish the appropriate title before treating the generation asset as ordinary on-site self-production.
The distinction is also commercially significant because the concession framework determines the developer’s rights, obligations, duration, infrastructure arrangements and treatment of electricity supplied beyond the industrial site.
ARSEL’s current sector titles framework confirms that industrial production and transmission are treated within the concession structure.
4. How a strategic industrial project can obtain its concession
For ordinary concessions, the electricity legislation provides for competitive tendering. However, the implementing framework creates a different route for qualifying strategic industrial projects.
Under the relevant provisions of Decree No. 2012/2806/PM of 24 September 2012, a strategic industrial development may be considered for a concession without the ordinary tender process.
The process can be understood in two principal stages.
Stage 1: Establishing the strategic basis
The applicant submits information to the ministry responsible for electricity, including the nature of the proposed activity, the relevant sites, expected power requirements, implementation timetable and technical characteristics of the proposed facility.
The administration then determines whether the development qualifies for the strategic treatment and whether the concession can proceed through a negotiated process.
The applicable procedure provides for a maximum period of 60 days for this determination.
Stage 2: Preparing and granting the concession
Once the strategic route has been accepted, the applicant submits the full concession application to the regulatory agency. The Agency prepares the draft concession within the prescribed period, after which the administration decides whether to grant or refuse the title.
The framework provides for a 60-day period for preparation of the concession title and a further 30-day period for the administration’s decision.
For a major industrial investment, these statutory timelines should be incorporated into the development schedule rather than treated as an administrative afterthought.
ARSEL maintains an official repository of electricity-sector decrees and related regulatory instruments.
5. What happens to excess generation?
This is often the most commercially interesting part of an industrial generation structure.
Article 57 of the Electricity Law establishes the framework for electricity produced under an industrial generation concession beyond the quantity required by the industrial operator. The agreed quantity is made available to the transmission network concessionaire or operator for supply to public or private buyers.
The implementing decree provides additional detail on how that excess output is handled. Article 38 places the agreed quantity at the disposal of the transmission network manager and establishes the framework under which the additional electricity may subsequently be supplied to eligible market participants.
This means that Steel 1 should not assume that it can simply connect its generator to a neighbouring factory and negotiate a private electricity sale independently of the regulated system.
The commercial route depends on the applicable concession, network arrangements and regulatory framework. Depending on the structure, the downstream purchaser may include an eligible distribution concession holder, electricity sales licence holder or another permitted industrial arrangement under the applicable rules.
The key point for investors is therefore simple: excess generation can have commercial value, but that value must be structured within the electricity market framework.
6. The tariff for excess power is not simply a negotiated number
Once additional output is introduced into the market, the next issue is pricing.
Article 57 provides for the tariff treatment of electricity made available under the industrial generation framework, while the implementing decree establishes the basis for determining the applicable price.
The regulatory approach is linked to the cost of service. Relevant components can include investment expenditure, financing costs, return on equity, operation and maintenance expenses and applicable taxes.
This is consistent with ARSEL’s broader tariff methodology, which emphasizes cost reflectivity, recovery of efficient costs, investment viability and transparency.
Developers should therefore avoid building their financial model around an assumed market price for excess power. The commercial value of that output needs to be tested against the applicable regulatory and contractual mechanism.
ARSEL’s current tariff principles and tariff decisions provide useful reference points for understanding the broader pricing framework.
7. The transmission system becomes critical when power leaves the industrial site
A facility that produces power exclusively for its own operations has a very different infrastructure requirement from one designed to place additional output onto the national system.
Once the industrial installation interacts with the national transmission network, questions of interconnection, system integrity, capacity, metering, dispatch and network charges become central to the investment case.
Article 56 is particularly relevant where an industrial transmission line is interconnected with the national network. It provides a framework for third-party access, subject to technical and operational conditions designed to protect the integrity and security of the system.
This creates an important planning consideration: a private transmission asset developed for an industrial facility may eventually have wider network implications.
This is one reason why transmission design, interconnection studies and regulatory engagement should begin well before commissioning.

8. Land rights and the question of public utility
Land can become one of the least visible but most consequential issues in an industrial power development.
Article 51 provides important rights associated with industrial production and transmission concessions, including the ability to occupy public-domain areas within the concession perimeter and rights concerning land use and works within the relevant transmission right-of-way.
At the same time, Article 53 provides that works associated with industrial generation or transmission concessions and their related installations may, where applicable, be preceded by a declaration of public utility.
This should not be interpreted as an automatic entitlement to expropriation or compulsory acquisition for every industrial facility. The application of a declaration of public utility depends on the circumstances and the applicable administrative process.
For developers, the practical lesson is to address land access, rights-of-way and public-domain occupation during concession negotiations. Coordination with the relevant land administration should also form part of the project development plan.
9. Captive generation is not the same as Cameroon’s mini-grid regime
Industrial sponsors should also distinguish captive generation from mini-grid development.
A mini-grid is generally designed to serve multiple users or a defined local electricity market, while an industrial generation facility is principally structured around the requirements of the industrial operator.
The distinction becomes important when considering distribution rights, tariff arrangements, licensing, grid arrival risk and third-party supply.
We examined these issues in more detail in Cameroon Mini-Grids: Regulation, Investment and the Practical Barriers Developers Face.
10. What Steel 1 should structure before financial close
For an industrial operator considering a 30 MW facility against a 20 MW base requirement, the regulatory strategy should be developed alongside the engineering and financial model.
- Define the primary load: establish the industrial demand profile, minimum operating requirement, expansion assumptions and expected utilisation.
- Determine the appropriate legal title: confirm whether the proposed structure falls under the industrial production concession framework and whether a separate transmission concession is required.
- Establish the treatment of excess output: determine how additional generation will be allocated, transferred and commercialised under the concession.
- Model the economics carefully: do not assume that every additional megawatt automatically becomes a profitable merchant-power stream.
- Address interconnection early: establish technical requirements, network capacity, metering, protection, dispatch and system-security conditions.
- Secure land and rights-of-way: identify private and public land requirements before construction contracts are finalized.
- Build regulatory timelines into financing: concession processing, technical studies and approvals can affect the financial close date.
- Protect future expansion: structure the concession and infrastructure so that additional industrial loads can be accommodated where commercially justified.
11. The bankability question: build for reliability, or build for the market?
The most important strategic decision is not necessarily whether an industrial company should build its own generation facility. It is how much capacity it should develop and what role that capacity is expected to play over the life of the investment.
A facility sized only for current consumption may minimise initial capital expenditure but leave little room for expansion or operational resilience.
A larger installation can create additional flexibility, but the excess capacity should not be treated as guaranteed merchant revenue until the regulatory pathway, network arrangements, eligible buyers and tariff methodology have been established.
For lenders and investors, this distinction matters. The base industrial load may underpin the core business case, while revenue from additional generation should be treated according to the level of contractual and regulatory certainty supporting it.
12. What industrial developers should take away
Cameroon’s electricity legislation provides industrial companies with a route to develop dedicated generation and associated transmission infrastructure. But the legal framework is more structured than a simple “build your own plant” model.
For a major industrial facility, the critical questions are:
- What legal title governs the generation facility?
- Is a separate transmission concession required?
- How will additional production be treated?
- Through which network and market participants can that output be supplied?
- How will the applicable tariff be determined?
- What interconnection and third-party access rights apply?
- What land and right-of-way protections are available?
- How should the structure be reflected in the project’s financing model?
These are not secondary legal questions. They can influence the plant’s optimal capacity, capital structure, projected revenue, construction schedule and ultimately its bankability.
For industrial investors evaluating on-site generation, the strongest approach is therefore to treat electricity regulation as part of the project architecture from the beginning—not as a compliance exercise after the engineering design is complete.
My advice to industrial sponsors: do not model captive generation solely around the megawatts your factory needs today. Establish the legal title, interconnection route, treatment of additional output, tariff mechanism and land requirements before committing to the final plant configuration. A technically sound power facility can still become difficult to finance if its regulatory and commercial structure is left unresolved.
