Powering 500+ Telecom Towers
Across Africa
How a pan-African telecom operator transitioned hundreds of remote tower sites from diesel generators to Clear Blue managed solar power, cutting operational costs while improving network uptime.
The Challenge
The operator managed a portfolio of 500+ cell towers spread across multiple countries in Sub-Saharan Africa. Most of these towers sat in remote locations where grid connections were either nonexistent or too unreliable to depend on. Diesel generators were the primary power source at every site.
The costs were staggering. Fuel deliveries to remote sites required dedicated logistics chains. Theft accounted for a significant portion of fuel budgets. Generators needed servicing every few hundred hours, and every service call meant dispatching a technician to a location that might be a full day's drive from the nearest depot.
When a generator failed between scheduled visits, the tower went dark. No power meant no network. Subscribers experienced outages, revenue was lost, and the operator faced SLA penalties. The team needed a way to power these sites reliably without the diesel dependency that was draining their operating budget.
Diesel costs consuming operating budgets
Fuel, transport, theft, and maintenance at 500+ sites added up to millions per year.
Reactive maintenance model
Every issue required a truck roll. No way to see problems before they caused outages.
Distributed across multiple countries
Sites spread across different regulatory environments, climates, and logistics networks.
The Solution
The operator chose Clear Blue's Energy-as-a-Service model. Rather than purchasing and managing power equipment themselves, they contracted Clear Blue to deliver reliable power as a managed service with a predictable monthly cost.
Clear Blue deployed Nano power packs at each site. These pre-configured, plug-and-play solar-battery systems were designed specifically for the load profiles of telecom base stations. Each system included built-in cellular communications connecting it to the Illumience cloud platform.
From day one, Clear Blue's operations team had full visibility into every system in the fleet. Illumience tracked battery health, solar generation, load patterns, and weather conditions at each site in real time. When a battery started degrading, the team was alerted weeks before it would affect service. When a storm was approaching, the platform pre-charged batteries and adjusted load profiles automatically.
The Results
The transition delivered measurable improvements across every metric the operator cared about.
Average Uptime
Sustained across the entire fleet, measured per-site
Fewer Site Visits
Illumience remote management replaced routine dispatches
Diesel Reduction
Dramatic drop in generator runtime and fuel consumption
Sites Managed
Fleet-scale deployment across multiple countries
Diesel consumption dropped dramatically as the hybrid systems handled the vast majority of power generation through solar and battery. Site visits fell by 60% because Illumience's remote monitoring and troubleshooting eliminated the need for routine inspections and blind diagnostic trips.
Most importantly, the network achieved 99.5% average power uptime across the entire fleet. Subscribers experienced fewer outages. Revenue losses from downtime dropped. And the operator converted unpredictable diesel and maintenance costs into a fixed monthly operating expense.
Key Takeaways
Managed service beats buy-and-own at scale
Managing 500+ power systems across multiple countries is a full-time job. EaaS transfers that burden to a specialist while giving you better uptime.
Remote monitoring changes the maintenance model
With Illumience, the operator went from reactive (send a truck when something breaks) to proactive (fix it remotely before it causes an outage).
Diesel displacement is real and measurable
The 70%+ reduction in generator runtime translated directly to millions in fuel and logistics savings.
Pre-configured systems accelerate deployment
Nano's plug-and-play design meant sites could be transitioned in days, not weeks. No custom engineering at each tower.
