An adequate power supply underpins any economy. However, Zambia has struggled to generate enough electricity to meet growing demand as the country has developed. This longstanding issue came to a head in 2015/16 when poor rains depleted the hydroelectric power stations which provide over 80% of Zambia’s power. The ensuing load-shedding had severe consequences for the economy, as businesses scaled back production, small to medium sized enterprises struggled and households experienced blackouts, with the total impact estimated to be equivalent to 20% of annual GDP. As demand continues to grow, it is essential that Zambia gets energy generation right if the country is to fulfill its potential for growth.
