Watts in Store
Part 1: Explainer on how energy storage can help South Africa's electricity crisis
South Africa has an electricity crisis where national supply is often unable to meet demand, leading to regular, planned power cuts. This report aims to explain how energy storage can provide a wide range of benefits to a constrained power system, and why grid-located batteries emerge as a strategic priority in the short term.
The declining performance of South Africa's coal fleet and grid constraints to adding new power plants reinforce the need for measures like energy storage that can maximize the use of existing infrastructure.
Energy storage—and particularly batteries in the short term—can help balance electricity supply and demand, improve grid stability, and boost energy providers' financial returns.
South Africa needs national and municipal grid storage strategies that will provide a positive signal to the energy storage industry that it can develop local supply chains.
Watts in Store Part 1 is the first in a two-part series about energy storage in South Africa. It explores how energy storage can contribute to solving the electricity crisis in South Africa, summarizes seven key benefits for the country, and gives the status quo of current plans and projects. International trends point to the rapid growth in grid-located batteries, and Part 2 of this series will take a deeper look at grid-located batteries in South Africa: how to maximize benefits, minimize risks, and create a more enabling environment for deployment.

A new report finds South Africa should develop national and municipal plans to deploy energy storage to ease the current electricity crisis and reduce the need for load shedding during periods of peak power demand.
Don’t write off the Just Energy Transition Partnership just yet
When it was announced at COP26 in 2021, South Africa's Just Energy Transition Partnership seemed to offer an answer to a weighty question: how can we not only usher in large-scale renewables investment into developing countries, but also rapidly wind down their coal sectors? However, in the nearly two years since the JETP was announced, critics have taken issue with everything from the way the JETP packages are funded to the pace at which they are being rolled out.
Just Energy Transition Partnerships and How They Work
To limit the damage caused by climate change, the world needs to rapidly reduce carbon dioxide emissions everywhere, not just in rich countries. To get there, poor and middle-income places will require trillions of dollars for replacing coal plants with cleaner energy, improving electrical grids and retraining workers, among other measures. Just Energy Transition Partnerships, or JETPs, are among the most high-profile financing mechanisms designed to funnel money from wealthy economies to some of the bigger developing-world emitters for the purpose of weaning off fossil fuels. South Africa signed the first agreement in 2021, and a handful of others are getting off the ground, including in Indonesia. But the process has been slow and politically fraught, raising the question of whether such flagship plans can be inclusive, effective and timely enough to fulfill their promise.
