Isuzu Warns Soaring Electricity Tariffs Threaten South Africa’s Manufacturing Competitiveness

South Africa’s manufacturing sector is facing mounting pressure from escalating electricity tariffs, with Isuzu Motors South Africa warning that energy costs have become a critical barrier to industrial growth and investment. The country’s largest truck manufacturer has urged policymakers to introduce targeted electricity pricing support for industry, arguing that sustained tariff increases threaten the competitiveness of local manufacturing despite recent improvements in power reliability.

Speaking at the Manufacturing Indaba, IMSA President Billy Tom revealed that electricity prices have climbed by more than 700% since 2007, dramatically increasing operating costs for manufacturers already contending with inflationary pressures, higher input costs and growing international competition. He cautioned that electricity affordability has overtaken supply reliability as one of the most significant challenges confronting South Africa’s industrial base.

While the reduction in load shedding has improved operational certainty for businesses, manufacturers say the financial burden of electricity is now constraining expansion plans and weakening South Africa’s appeal as a manufacturing destination.

Tom called for targeted tariff relief for energy-intensive industries, arguing that internationally competitive electricity pricing is essential to support domestic production, stimulate investment and safeguard employment. Without intervention, he warned, rising power costs could erode the competitiveness of locally manufactured products in both domestic and export markets.

The concerns mirror those of manufacturers across multiple sectors, many of whom acknowledge progress in stabilising the electricity system but contend that rapidly rising tariffs continue to undermine productivity and profitability.

As one of South Africa’s leading automotive manufacturers, Isuzu Motors South Africa produces commercial trucks and bakkies for local and international markets from its facilities in Gqeberha. The automotive industry remains a cornerstone of South Africa’s manufacturing economy, supporting exports, employment and industrial development.

Industry stakeholders argue that sustained increases in electricity tariffs risk offsetting the benefits of a more reliable power system. Higher energy costs, they say, could encourage manufacturers to redirect future investment towards markets offering lower production costs and more competitive industrial energy pricing.

The warning highlights a broader shift in South Africa’s energy debate. With electricity availability improving, attention is increasingly turning to affordability as a decisive factor in industrial competitiveness. For manufacturers assessing long-term investment opportunities, access to reliable electricity must now be matched by cost-reflective tariffs that enable South Africa to compete effectively as a regional manufacturing hub.
