Municipalities race to submit electricity tariff applications

South Africa's electricity distribution landscape faces a critical juncture as municipalities scramble to finalize tariff applications ahead of a March 31 deadline set by the National Energy Regulator of South Africa (Nersa). While state-owned Eskom will implement a relatively modest 8.76 percent tariff increase effective April 1, 2026, municipal electricity distributors are poised to impose significantly steeper hikes when their rates take effect on July 1—creating a two-tier pricing structure that fundamentally alters the investment calculus for European businesses operating in the country. The disparity between Eskom's increase and municipal rates represents a critical structural inefficiency within South Africa's energy distribution system. Where Eskom customers face a single-digit burden, municipalities—particularly major metropolitan areas like Johannesburg—are expected to implement average increases of 9.01 percent, with preliminary indications suggesting some distributors could exceed double digits when accounting for municipal markups and surcharges. This divergence stems from municipalities' practice of adding their own profit margins and cost recovery mechanisms to Eskom's wholesale rates, effectively creating a "middleman penalty" for customers served by local authorities. Recent innovations in municipal tariff structures amplify this challenge. Johannesburg's introduction of fixed monthly surcharges for prepaid electricity customers represents a paradigm shift that particularly impacts small to medium-sized
