El Dorado Tech - Containerized Solar EV Charging

West Africa - Sahel focus (Mauritania, Senegal, Western Sahara, Mali, Cabo Verde, neighbors)

Executive summary

El Dorado Tech will deploy containerized, off-grid EV charging stations optimized for a “leapfrog” infrastructure rollout across: - Mauritania - Senegal - Western Sahara - Mali - Cabo Verde - and bordering nations

Initial strategy: - Charger mix from day 1: mixed AC + DC - Site priority: fleet depots first, then municipal hubs, then corridor fuel stations - Early adopters: mostly PHEVs, followed by e-motorbikes and 3-wheelers (full EVs later)

This implies a product and rollout that is less about ultra-fast highway charging and more about: - dependable, secure, managed charging at depots and hubs - fleet billing + mobile money / QR payments - moderate DC capability (40-60 kW) for turnaround, exceptions, and eventual full EV volume

Inspiration: telecom leapfrogging

Many African markets leapfrogged traditional fixed-line telecommunications by adopting cellular and microwave networks first. Charging can follow a similar pattern: instead of waiting for long lead-time grid upgrades, deploy modular stations that bring their own generation (solar), storage (batteries), and connectivity (cellular).

Key parallels: - Reduce dependency on legacy prerequisites (no trenching, transformers, or interconnect delays for v1 deployments). - Start small, replicate fast (standard container + canopy kit, repeatable installation playbook). - Use existing wireless networks for payments, monitoring, and support.

1. Deployment thesis

1.1 Why this works in these markets

1.2 Cabo Verde-specific angle

Cabo Verde differs from the Sahel corridor markets: - It is an island nation: logistics and spares planning are more important. - Distances are shorter: corridor charging is less of a “long-haul” play, more of an urban + municipal + fleet/tourism play. - Card payments may be more relevant depending on customer mix (tourism, rentals), but QR and fleet accounts still matter.

2. Product definition (v1)

2.1 Recommended charger configuration (mixed AC + DC)

For PHEV-first markets with growth into full EV: - 1 x DC fast charger: 40-60 kW (single port) - 4 x AC points: 7-22 kW (plan for 7-11 kW typical draw; 22 kW when vehicles support it) - Optional later: second DC dispenser when utilization proves it.

Why this mix: - PHEVs often take smaller energy per session (often 5-15 kWh), and many do not benefit from very high power. - A single DC unit supports future full EVs and operational flexibility.

2.2 E-motorbikes and 3-wheelers support

Treat as a first-class revenue stream after PHEVs: - Add a low-cost “light EV” area: multiple protected AC outlets (1-3 kW each), or dedicated low-power EVSE. - Consider a partner-led battery swap model (optional) if local operators prefer swapping.

2.3 Power block (solar + storage)

Two practical v1 configurations:

Config A - Depot / Municipal (recommended starting point) - Solar canopy: 40 kWp - Battery: 200 kWh LFP - Supports: 60 kW DC + multiple AC sessions (topology dependent)

Config B - Corridor fuel station (higher throughput / higher resilience) - Solar canopy: 50-60 kWp - Battery: 250-350 kWh LFP - Optional generator input as emergency fallback (policy decision)

3. Site strategy

3.1 Fleet depots (primary)

3.2 Municipal hubs (secondary)

3.3 Corridor fuel stations (tertiary)

4. Pricing and payments

4.1 Pricing model

Two-track model: - Fleet contract pricing: lower price per kWh in exchange for minimum volume and/or monthly subscription. - Public pricing: higher per kWh; optional idle fees.

Ballpark per-kWh pricing bands: - Fleet depots: USD 0.30-0.40/kWh - Municipal hubs: USD 0.35-0.50/kWh - Corridor fuel stations: USD 0.45-0.70/kWh

4.2 Payments

5. Operations model

Cabo Verde ops note: - Plan for spares staging per island and clear shipment lanes for batteries/EVSE parts.

6. Financials (ballpark, USD)

6.1 Per-station CAPEX (deployed)

With mixed AC+DC from day 1:

Depot / Municipal Config A (typical): - Battery 200 kWh LFP + BMS + integration: 28k-38k - Solar 40 kWp canopy + inverter/MPPT + protections: 22k-32k - EVSE: 1 x DC 40-60 kW + 4 x AC: 18k-30k - Container refurb + internal framing/locks: 4k-7k - Wiring/grounding/comms/control: 4k-7k - Logistics + civil pad/anchors + commissioning: 6k-15k Total deployed: ~85k-125k

Corridor Config B (typical): Total deployed: ~110k-170k

Cabo Verde CAPEX note: - Expect a logistics premium vs Senegal (shipping, spares, island distribution). Budget +10-25% unless a strong local integrator reduces costs.

6.2 Fixed OPEX (per station per year)

6.3 Variable OPEX

6.4 Base-case utilization assumptions (PHEV-first)

6.5 ROI framing

For mixed AC+DC systems, ROI is most attractive when: - fleet depots provide anchored utilization - site cost is controlled (host terms / municipal partnership) - payment costs are minimized via fleet billing

7. Initial design and engineering (NRE)

NRE to reach manufacturable, serviceable v1: - Power + safety engineering: 180k-300k - Mechanical/canopy/container integration: 120k-180k - Backend + fleet billing + payments + app/web: 300k-550k - Pilot builds + travel + field debugging: 120k-250k - Compliance planning/testing (country-dependent): 80k-220k Total NRE (9-12 months): ~0.8M-1.5M

8. Rollout plan (region)

Phase 1 - Pilot (fleet-first): - 2 fleet depot sites in Dakar area - 1 municipal hub site - 1 Nouakchott depot site - (Optional) 1 Cabo Verde municipal or fleet/tourism hub site if logistics partner exists

Phase 2 - Cluster scale: - expand Dakar cluster to 8-12 sites - expand Nouakchott to 3-5 sites - expand Cabo Verde per-island clusters (start with 1 island, then replicate)

Phase 3 - Corridor sites: - add 2-4 high-confidence fuel-station corridor sites

9. Funding strategy (practical)

Blended capital stack is realistic: - equity for NRE + early pilots - asset-backed debt for deployments after utilization proven - municipal / climate / DFI co-funding for public hubs
