Consultancy Sizana Solutions says gravity energy storage systems (GESS) fit in “beautifully” with South Africa ’s just energy transition, as it can create multiple thousands of jobs while constructing energy storage assets and drive environmental restoration, especially at soon-to-be decommissioned coal -fired power stations.
This is according to a new report by the World Bank which says that over the next five years SA is expected to show rapid growth in energy storage demand. The rise in demand will come from the transformation of the energy system to include more renewables and developing demand in the electric vehicle (EV) sector...
Sizana, the appointed consultant of NYSE-listed Energy Vault in Southern Africa, affirms that there are multiple viable opportunities for GESS in the country, particularly as it offers a lower life cycle cost compared with most other energy storage mediums owing to to its long life and no degradation.
Importantly, more than 80% of the content required for an Energy Vault GESS system can be manufactured or is already being manufactured in South Africa, whereas battery components are mostly imported. There is also no limit to the number of cycles GESS can do with a roundtrip efficiency above 80% and an availability of 95%.
Moreover, Lange states that some of the older power stations have an estimated 35-million tonnes of accumulated ash that needs to be disposed of in a safe manner, as is the case at the Grootvlei power station. One can only imagine the liability of having to ensure those ash dumps never pollute the environment.
For example, Energy Vault’s first full-scale GESS project in China is built on a 1.2 ha piece of land. That said, the project is large at 25 MW for four hours or 100 MWh. Lange estimates that every megawatt-hour requires 120 m 2 of space, with a height of between 120 m and 140 m. Energy Vault’s GESS project in China will be commissioned this year.
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%. Europe follows closely with 35% market share, where standardized industrial storage designs have cut installation timelines by 65% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 50% CAGR, with manufacturing scale reducing system prices by 20% annually. Emerging markets in Africa and Latin America are adopting industrial storage solutions for peak shaving and backup power, with typical payback periods of 2-4 years. Major commercial projects now deploy clusters of 15+ systems creating storage networks with 80+MWh capacity at costs below $270/kWh for large-scale industrial applications.
Technological advancements are dramatically improving industrial energy storage performance while reducing costs. Next-generation battery management systems maintain optimal operating conditions with 45% less energy consumption, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $85/kWh to $40/kWh since 2023. Smart integration features now allow multiple industrial systems to operate as coordinated energy networks, increasing cost savings by 30% through peak shaving and demand charge management. Safety innovations including multi-stage fire suppression and thermal runaway prevention systems have reduced insurance premiums by 35% for industrial storage projects. New modular designs enable capacity expansion through simple system additions at just $200/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial and industrial projects typically achieving payback in 3-5 years depending on local electricity rates and incentive programs. Recent pricing trends show standard industrial systems (1-2MWh) starting at $330,000 and large-scale systems (3-6MWh) from $600,000, with volume discounts available for enterprise orders.
