Meters in a warehouse do not stop electricity theft.

Africa's biggest smart metering programmes are proving that procurement is the easy part. The number that actually matters is how many meters get bolted to a wall.

Every large African metering programme now reports two numbers: meters procured and meters installed. The gap between them is quietly becoming the most important figure in the sector, more telling than headline investment totals or target counts. A meter in a warehouse produces no revenue, stops no theft and tells no distribution company anything about its network. Only an installed meter does that.

Nigeria's undeployed stock

Nigeria's Distribution Sector Recovery Programme, backed by $500 million from the World Bank, illustrates the pattern clearly. Of just over one million meters delivered under the first phase, 668,000 have been installed on customer premises. That leaves 365,000 delivered meters sitting idle, procured and paid for but not yet doing any work. A legal injunction over procurement, since withdrawn, held up the second phase, which targets roughly 1.55 million meters against an overall national goal of 3.2 million.

Sixty per cent conversion from delivery to installation is not a failure. It is what a large rollout actually looks like once legal, logistical and community friction enters the picture. The mistake is reporting procurement milestones as if they were deployment milestones. They are not the same achievement, and treating them as equivalent understates how much work remains and how much revenue is still being lost while boxes sit on shelves.

Eskom's other blocker

South Africa's experience shows the gap can open for reasons that have nothing to do with logistics. Eskom has deployed 1,861,180 smart meters nationwide, with 472,100 targeted at load-reduction feeders in Gauteng, Mpumalanga, Limpopo and KwaZulu-Natal, the areas with the worst losses and illegal connections. But Eskom itself reports that safety incidents, intimidation and work stoppages have delayed more than 122,000 planned installations.

That figure sits alongside the 472,100 already installed on high-loss feeders, meaning delayed installations are running at roughly a quarter of that priority-area total. In the neighbourhoods where smart metering does the most good, by stopping theft and correcting billing, it is also the hardest to install, because those neighbourhoods are often the ones with the most to lose from being metered accurately.

Scale magnifies the gap

Smaller programmes make the same point at lower volumes. Cameroon has begun deploying 20,000 smart meters against estimated annual losses of CFA 60 billion, a rollout coordinated through a new state utility structure following the replacement of the previous operator. At that scale, delivery and installation can be tracked meter by meter. At Nigeria or Eskom's scale, the tracking itself becomes a management problem, and a five or ten point gap between delivered and installed translates into hundreds of thousands of units and real revenue sitting unrealised.

None of this argues against the scale of ambition. It argues for measuring the right thing. A programme that reports meters procured, meters delivered and meters installed as three separate, honestly tracked figures gives funders, regulators and utility boards a much more useful picture than a single headline number ever will. It also surfaces the actual bottleneck, whether that is legal, logistical or a matter of on-the-ground consent, early enough to fix it rather than discovering it two years into a five-year target.
