South Africa has committed to pursue improved energy efficiency to encourage a sustainable development of its energy sector. In 2016, the Department of Energy (DoE) implemented the first Energy Efficiency Standards and Labeling (S&L) program in the country, covering 7 major residential products and resulting in energy savings equivalent to the generation output of an 800 MW plant.
Lawrence Berkeley National Laboratory (LBNL) has been assisting DOE since 2013 by providing recommendations and technical analyses to inform the development of the S&L program. As part of this collaboration and under the auspices of the Energy Efficiency for Development program (EE4D), LBNL published in 2020 the study South Africa’s Appliance Energy Efficiency Standards and Labeling Program; Impact Assessment, which describes the methodology, assumptions and results of a stock turnover modeling tool that estimates the energy savings achievable by South Africa’s S&L program in the residential sector.
The study shows that if regulations are effective in 2021 for 10 major end-uses adopting international standards best practices, 6 terawatt-hours (TWh) will be saved in 2030 and 9.5 TWh will be saved in 2040, representing a CO2 mitigation of 3.7 megatonnes (Mt) in 2030 and 5.8 Mt in 2040. This outcome will contribute to the South African government’s international commitment to tackling climate change through its National Determined Contribution (NDC).
