The 3 Challenges of Deploying SCADA for Power Grids in West Africa

A SCADA system (Supervisory Control And Data Acquisition) is now the central nervous system of any modern power grid. It controls, monitors and logs thousands of measurement and command points spread over hundreds of kilometers. Where international engineering handbooks describe "ideal" architectures designed in European engineering offices, the West African reality demands very specific technical, climatic and human adaptations. Drawing on our field experience in Côte d'Ivoire and Burkina Faso, here are the three structural challenges — and how they are solved.

In Scandinavia or France, connecting an MV substation to a SCADA control center relies almost exclusively on dedicated fiber optics. Copper telephone networks are being phased out, and radio links are marginal. Reliability exceeds 99.99%.

In West Africa, fiber-optic coverage is highly uneven. The city centers of Abidjan, Ouagadougou and Conakry are well covered, but just a few dozen kilometers away — precisely where many strategic MV substations are located — fiber becomes scarce or nonexistent. The question then becomes: how do you guarantee reliable telecontrol over heterogeneous links?

The solution: a multi-carrier architecture with automatic failover

Rather than depending on a single type of link, we design architectures with two levels of redundancy:

Failover between the primary and backup links must be transparent to the SCADA system. To achieve this, our telecontrol cabinets integrate industrial routers supporting multi-WAN with failover, and the network architecture uses robust VPN tunnels (IPsec) that re-establish themselves automatically whatever the physical medium.

The pitfall to avoid: false savings on the router

A consumer-grade router at 50,000 CFA francs may look tempting for a rural site. It is a mistake. In a remotely controlled substation, the router must withstand cabinet temperatures of +50°C, lightning surges, remotely monitored restarts, X.509 certificates, detailed logging and secure remote updates. A certified industrial router costs 10 times more but lasts 10 times longer and avoids dozens of field interventions.

"A successful SCADA project in West Africa is not the one with the best technology; it is the one that degrades gracefully when a link goes down — and recovers without human intervention."

On a European manufacturer's datasheet, you will proudly read "operating temperature: -25°C to +70°C". In reality, this equipment is rarely tested over long cycles combining heat, humidity, dust, sea salt and thunderstorms. That is precisely the cocktail faced by every electrical substation between Abidjan, Lomé and Cotonou.

The typical failure patterns we observe:

• Accelerated corrosion of connectors and screw terminals in coastal areas (sea salt);
• Internal condensation inside cabinets during the rainy season, short-circuiting electronic boards;
• Premature aging of backup batteries (actual service life often half the advertised figure due to cabinet temperatures above 35°C);
• Degradation of insulation and gaskets under intense UV exposure and day/night thermal cycles;
• Devastating atmospheric surges: Côte d'Ivoire is one of the most lightning-struck areas on the planet (with one of the highest keraunic densities in the world).

The solution: over-specify and design for maintenance

ENERTEC's design standard for tropical telecontrol cabinets:

• IP54 protection rating minimum (IP65 in coastal areas), with O-ring seals checked at every opening;
• Cabinets made of reinforced polyester or 304 stainless steel rather than painted steel (10x higher corrosion resistance);
• Filtered natural ventilation from the bottom (cool air intake) and the top (hot air exhaust) — limits condensation while keeping dust out;
• Three-stage cascaded surge arresters: Type 1 on the AC supply, Type 2 on circuit protections, Type 3 on Ethernet ports and telemetry signals;
• Oversized earthing circuits (35 mm² minimum for exposed conductive parts, earth resistance below 10 Ω);
• Lithium iron phosphate batteries (LiFePO₄) rather than lead-acid: more durable in tropical heat (though more expensive upfront);
• Modular design allowing a faulty module to be replaced without full disassembly (saving time during field work).

The "6-Month Tropical Test"

Before any large-scale rollout, we systematically recommend a pilot of at least 6 months on 3-5 representative sites covering both the dry season and the rainy season. This pilot phase reveals unforeseen failure modes (ants inside cabinets, localized condensation, radio interference from nearby 3G relays, etc.) and allows the design to be adjusted before mass deployment.

The most underestimated challenge — and yet the most decisive. A SCADA system in West Africa can be technically flawless: if the local operations and maintenance teams do not master the tool, its operational value collapses within 12-24 months. Degraded modes set in, alarms are no longer interpreted, data is no longer used for planning, and the system gradually becomes a dormant investment.

This challenge plays out over three time horizons:

Short term: initial training

During deployment, we insist that local teams be involved from the design phase onwards, not just at commissioning. In practical terms:

• Skills-transfer sessions every Friday throughout the project (rather than a one-week block of training at the end of the project, quickly forgotten);
• Documentation in French written by the local engineers themselves (forcing ownership and guaranteeing field relevance);
• Creation of a SCADA simulation environment identical to production, where operators can safely practice real switching operations.

Medium term: retaining skills

An engineer trained on a proprietary SCADA system becomes a rare — and therefore coveted — resource. Without a career plan, they will leave for a competitor or move abroad within 2-3 years, taking a crucial share of the operational know-how with them. Good practices we have observed:

• Formalized technical career paths (junior → senior → expert → SCADA architect);
• Vendor certifications funded by the employer, with a contractual retention commitment;
• Cross-company communities of practice (CIE, ENERTEC and certain equipment manufacturers organize annual technical days).

Long term: a local training ecosystem

The structural challenge for West Africa is to develop local curricula in industrial automation, industrial telecommunications and OT cybersecurity. A few initiatives already exist — INP-HB in Yamoussoukro, ESATIC in Abidjan — but demand still massively outstrips supply.

We believe that school-industry partnerships are the most effective route: long internships, final-year projects based on real cases, professionals teaching as adjunct lecturers, contributions to skills frameworks. This is how ENERTEC contributes to building skills across Africa's energy sector.

In summary: a successful SCADA project stands on three legs

From our experience across dozens of remotely controlled substations in Côte d'Ivoire — including the ENERGOS project, which remains to this day the largest MV network telecontrol deployment ever carried out in the country — we draw one strong conviction: a successful SCADA project in West Africa is one that manages to balance three pillars:

1. A resilient architecture that anticipates connectivity failures rather than suffering them;
2. Equipment over-specified for the tropical climate, rather than blindly importing European standards;
3. A long-term human strategy to guarantee ownership and durability.

Cutting corners on any one of the three pillars jeopardizes the entire investment. It is precisely this holistic engineering discipline — not any single technical feat — that separates projects that last 20 years from projects that decay within 5.
