S/02 · POWER-AS-A-SERVICE
Metered AC and 48V DC power with a 99.95% availability SLA at every site.
// What it is
What the service covers.
Power-as-a-Service (PaaS) means African Towers owns and manages all power infrastructure at each site: ECG/NEDCo grid connection, automatic transfer switch, diesel generator, rectifiers, 48V DC bus, batteries and remote battery management system (BMS). Tenants connect their equipment to the DC bus or AC distribution panel and pay a monthly metered energy bill. African Towers' 24/7 NOC monitors power availability in real time; field teams dispatch for generator service, fuel top-up and fault rectification. The 99.95% availability SLA covers the full AC/DC supply chain.
// Who it's for
Built for these infrastructure users.
- All African Towers colocation tenants — PaaS is the default power model
- Third-party site owners seeking outsourced power management
- Off-grid or peri-urban sites where grid reliability is low
// How it works
The shared-infrastructure model explained.
Power infrastructure is shared across all tenants at a site. African Towers invests in a single, robust power system sized for full multi-tenant load; tenants pay proportional metered charges. Economies of scale mean each tenant pays less than they would managing their own generator-and-battery stack, and shares the burden of fuel logistics and maintenance.
// Process
From brief to live — every stage managed.
-
01
Load planning — African Towers models each tenant's expected AC and DC load at sign-on, sizing the system for full tenancy plus 20% growth headroom.
-
02
Infrastructure installation — ECG/NEDCo grid connection, ATS, generator, rectifier and battery stack installed as part of site build or upgrade.
-
03
Remote monitoring onboarded — each site's power system connected to the NOC via BMS and SCADA; alarms configured for grid fail, low fuel, battery degradation and temperature.
-
04
Live operation — NOC monitors 24/7; field team dispatches within SLA window on any alarm; monthly metered invoice issued per tenant.
// Proof points
Performance you can hold us to.
- 99.95% power availability across the managed fleet — confirmed by NOC data
- Generator fuel managed by African Towers; zero fuel-theft risk for tenants
- Battery replacement on African Towers' balance sheet — no surprise capex for operators
- 24/7 NOC with sub-15-minute alarm-to-dispatch SLA
- Remote BMS telemetry on all sites — proactive fault detection before outage
Frequently asked questions
- What does "Power-as-a-Service" mean?
- It means African Towers owns and manages the entire power supply chain at each site — from grid connection through to the DC bus on your equipment shelf — and you pay a metered monthly charge for the energy you consume. No generator ownership, no fuel contracts, no battery replacement, no power infrastructure capex.
- What does the 99.95% availability SLA cover?
- The 99.95% SLA applies to the AC/DC power supply delivered at the tenant's equipment interface point. It covers both planned maintenance (scheduled within agreed maintenance windows) and unplanned outages. 99.95% equates to less than 4.4 hours of downtime per year. Service credits apply if the SLA is missed.
- What happens when the grid fails?
- Each site has an automatic transfer switch (ATS) that detects grid failure and starts the backup diesel generator within 10–15 seconds. The battery system bridges this gap with no interruption to DC loads. The NOC receives an alarm immediately and dispatches fuel if generator run-time projections indicate a top-up is needed before grid restoration.
- Do you offer power management for sites African Towers did not build?
- Yes. African Towers can take on power management (PaaS contract) for third-party tower sites where the owner wishes to outsource generator and battery operations. A site survey and power audit are conducted first; the NOC and field operations are then extended to cover the site.
