South Africa is turning to development finance to speed up the expansion of its electricity transmission network, with the Development Bank of Southern Africa (DBSA) and National Transmission Company South Africa (NTCSA) signing a partnership aimed at improving infrastructure delivery and attracting investment into the power grid. The two institutions signed a memorandum of understanding (MoU) to collaborate on the preparation, financing and implementation of transmission projects as South Africa seeks to connect new electricity generation capacity and strengthen energy security.

The agreement brings together NTCSA’s responsibility for planning, developing and operating the national transmission network with DBSA’s experience in infrastructure financing and project preparation. Under the partnership, the institutions will work on transmission infrastructure development, financing structures, institutional capacity building, programme implementation and regional transmission interconnection projects aligned with South Africa’s Transmission Development Plan.

South Africa’s energy transition has increased pressure on the country’s transmission system, as renewable energy projects and other new generation capacity require additional grid infrastructure to connect to consumers. “Expanding South Africa's transmission network is fundamental to unlocking new generation capacity, improving energy security and supporting inclusive economic growth,” Monde Bala, chief executive officer of NTCSA, said.

DBSA Chief Executive Officer Boitumelo Mosako said the scale of the required transmission expansion would require cooperation between technical institutions, financiers and investors. “The scale of South Africa's transmission expansion requires strong partnerships that combine technical capability with innovative financing solutions,” Mosako said. The partnership is expected to support efforts to mobilise capital from development finance institutions, multilateral lenders and institutional investors for transmission projects.

South Africa has identified grid expansion as a critical requirement for its energy transition, with limited transmission capacity emerging as a constraint on the deployment of new power projects, particularly in areas with significant renewable energy potential. DBSA and NTCSA said the collaboration would help establish a more resilient and modern electricity network capable of supporting economic growth, improving energy reliability and advancing the country's energy transition objectives.
