Zesco May 2026

Despite its domestic troubles, ZESCO plays a crucial role in the Southern African Power Pool (SAPP). It is a net exporter, and the stability of regional industry often depends on Zambian electrons. This creates a complex dynamic: when Zambia hoards power for its own citizens, it breaks regional contracts; when it exports, locals accuse the utility of selling their light to foreigners. ZESCO’s management of this balancing act defines its reputation as either a responsible steward or a greedy monopolist.

No essay on ZESCO would be complete without addressing the human factor. Despite being a cash-rich utility in theory, ZESCO has frequently faced financial insolvency. The narrative here is one of systemic inefficiency. High technical losses (aging infrastructure), commercial losses (illegal connections and meter tampering), and a politically sensitive tariff structure have crippled the corporation. Governments have historically resisted raising electricity prices to reflect true costs, fearing public backlash. Consequently, ZESCO often operates at a loss, unable to invest in maintenance or diversification (such as solar or wind). This has led to accusations of a "revolving door" of debt, where the utility survives on government bailouts rather than sound business principles. Despite its domestic troubles, ZESCO plays a crucial

This leads to the infamous "load-shedding" schedules. For the Zambian citizen, ZESCO is not defined by the days the lights are on, but by the hours they are off. During a deep crisis, businesses operate on generators, students study by candlelight, and water pumping stations fail. The paradox is cruel: a nation blessed with the mighty Zambezi River is held hostage by the clouds above it. ZESCO’s management of this balancing act defines its

In the final analysis, ZESCO is a case study in the challenges of state-owned enterprises in developing economies. It is a physical infrastructure—a vast network of dams, substations, and pylons stretching across savannas. But it is also a political and social contract. When ZESCO fails, it is not merely an electrical fault; it is a failure of governance. As climate change makes the Zambezi flow less predictable, the future of ZESCO will depend not on its old dams, but on its ability to diversify energy sources and reform its financial practices. Until then, every flicker of a lightbulb in Zambia remains a national referendum on the utility that holds the country’s destiny in its high-voltage wires. The narrative here is one of systemic inefficiency

ZESCO was born out of the nationalist fervor of the 1960s. Following Zambia's independence in 1964, the new government sought to break free from the colonial reliance on foreign-controlled energy. The creation of ZESCO, formalized in 1970, was a strategic move to nationalize electricity generation and distribution. The cornerstone of this vision was the Kariba Dam, a massive hydroelectric scheme on the Zambezi River. For decades, ZESCO stood as a proud monument to self-reliance, providing cheap, reliable power to the Copperbelt mines—the engine of Zambia’s economy—and lighting up homes in Lusaka and the rural hinterlands.
