Renewable energy mini-grids: An alternative approach to energy access in southern Africa

The document argues that while the SADC region faces severe energy pressures and a heavy reliance on coal and hydropower, renewable energy mini-grids offer a viable complement to national grid extension, particularly for rural populations. However, most current projects remain in the pilot phase due to unsustainable business models, vague policy frameworks, and a lack of private investment. The brief recommends adopting anchor-business-community (A-B-C) models and establishing clear regulatory frameworks to scale these solutions.

• The SADC region experiences significant energy deficits, with power production failing to meet demand. In 2015, the Southern African Power Pool (SAPP) had an available capacity of 52,589 MW, leaving a shortfall of 8,247 MW when accounting for reserve requirements.
• Electricity access in SADC member states is characterized by extreme disparities. As of 2012, only 42% of the region's 298 million people had access to electricity, with rates ranging from 100% in Mauritius to 12% in Malawi.
• The region's energy mix is heavily dependent on coal and hydropower, creating vulnerabilities to climate change and price volatility. Coal accounted for 62% of SAPP's installed capacity by 2015, while hydropower stood at 21%.
• Renewable energy mini-grids are viewed as a critical complement to grid extension, especially since the IEA estimates that nearly 60% of the additional generation needed for universal electricity access in Africa must come from off-grid solutions.
• Despite their potential, mini-grids in the SADC region are mostly in the pilot phase and contribute minimally to the total energy mix, with the exception of Seychelles. Scaling is hindered by low rural incomes, unattractive tariffs for the private sector, and a lack of affordable long-term finance.
• The 'anchor-business-community' (A-B-C) approach is identified as the most successful business model, where a large 'anchor' consumer provides steady revenue, allowing surplus power to be distributed to smaller businesses and households.
• Policy implementation in SADC countries is often biased toward large-scale grid extension, leaving decentralized solutions underfunded and viewed as temporary 'pre-electrification' measures.
