The AC premium
In Nouakchott, air conditioning isn't about comfort. It's what separates those who can work year-round from those who stop when it gets too hot.
A class marker
When people talk about air conditioning in northern capitals, they think comfort. In Nouakchott, it's something else entirely. An air-conditioned shop stays open in October. A shop without AC closes at 2pm. An air-conditioned office runs 12 months a year. A workshop without it loses a third of its productivity for four months.
Air conditioning is a class investment. Those who can afford it — the unit, the installation, and above all the electricity bill — are buying the right to work normally. Everyone else endures the compression described in the previous section. This isn't a metaphor. It's the concrete mechanism by which heat deepens economic inequality in Nouakchott.
Air conditioning in Nouakchott isn't about comfort. It's a class marker. Those who can afford it keep working. Those who can't, stop.
Where the numbers come from
To estimate the cost of commercial air conditioning in Nouakchott, we need three things: the number of commercial spaces, the equipment rate, and the electricity tariff.
Source: JICA 2018, Nouakchott Urban Master Plan, Table I-14. This includes shops, workshops, offices, and services — every economically-purposed space in the agglomeration.
Local estimate. No official data exists on AC equipment rates for Nouakchott's commercial spaces. The 1-in-3 figure is a declared estimate, consistent with observation. We also test 1/5 (low) and 1/2 (high).
SOMELEC professional rate. This is the effective rate, not the subsidised residential one. For a shop running an AC unit 8-10 hours a day during the hot months, the bill adds up fast.
Three scenarios
The total AC premium cost depends directly on the equipment rate — that's the most uncertain assumption. We show three scenarios to demonstrate the range.
Even in the most conservative scenario — only 1 in 5 spaces equipped — the bill exceeds 500 million MRU. That's money not going to investment, employment, or growth. It's the price businesses pay to maintain a temperature that allows work to happen.
What happens when the power cuts
There's one detail the numbers don't capture: power outages. In Nouakchott, the SOMELEC grid is fragile, and load shedding is frequent during peak demand — exactly when AC is most needed. When the power cuts, an air-conditioned shop loses its only advantage. Interior temperature climbs within minutes. The shopkeeper who was paying to stay open finds themselves in the same situation as someone without AC.
This isn't in our calculations — it's impossible to quantify properly. But it's real, and it means our AC premium estimate is probably conservative. The true cost includes productive hours lost during outages, perishable goods damaged, and accelerated wear on equipment that cycles on and off constantly.
What 869M MRU represents
869 million MRU is $24 million per year spent solely on electricity to air-condition commercial spaces. That's money leaving the productive economy to power compressors. It's not an investment. It's a tax on the right to work in bearable conditions.
