Kenya Power stopped raiding slum wires and out-sold the cartels on price

Nairobi is a city of 3.4 million people, about two million of whom live in informal settlements such as Kibera, Mathare and Korogocho. Until the mid-2010s most bought electricity from cartels running illegal lines: service was poor and dangerous, fires and electrocutions were common, and the utility answered with raids. From 2011 through 2013 Kenya Power focused on cutting off illegal connections, only to see them back within days — and found its own legal customers reselling power to neighbors.

The turnaround changed the product, not the policing. Kenya Power stopped raids and worked through community leaders to sell what legal power delivers: safety, reliability, affordability. GPOBA and IDA paid the utility for each new legal connection, letting the program offer hookups at 1,165 shillings (about $12) against the regular $150, payable in installments. Meters are read at the top of the line to prevent tampering, and customers buy prepaid chits in small increments — former vendors of illegal power moved into the legal chit trade.

The numbers moved fast. As of May 2014 the program had 5,000 new legal connections; by May 2015 it had 150,000 — a thirtyfold increase in a year. By project close, the World Bank counted 57,667 slum households connected under the output-based window — $510 from Kenya Power and government, $250 from IDA and $125 from GPOBA per connection — within 177,895 low-income households reached overall, while the utility connected 4.72 million customers against a 2.2 million target.

The model became the template for Kenya's national Last Mile Connectivity push from 2014, and the ICR credits a strong community-based approach as key to moving slum consumers off illegal and poor-quality supply. The Electricity Expansion Project closed rated Moderately Satisfactory, with the output-based aid mechanism assessed as highly effective — though the access push outran transmission investment and left the network overloaded.

Make legal power cheaper than stolen power

Legal power undercut stolen power on price, so switching no longer depended on enforcement — the cartels' business model simply broke.

Paying the utility per verified connection aligned its incentive with hookups actually delivered to homes, not assets installed on paper.

Community-based selling replaced raids with a product people wanted: safe wiring, brighter light, and a bill payable in small increments.

Prepaid keypads and top-of-line meter reading made collections safe for a utility that had written slum customers off as uncollectable.

Where the incumbent treats customers as thieves, the fix is commercial, not enforcement: subsidize the hook-up, pay on verified delivery, and let the community own the last mile.

Kenya Power's customer base reached 6.2 million by mid-2017, growing about 30 percent a year. The World Bank judged the OBA mechanism highly effective but noted it needs an implementation agency with resources to pre-finance work; the national last-mile push outran medium- and high-voltage investment, so network overload became the next constraint.
