Analysis of portable energy storage power supply field in south africa

Is energy storage a viable option for South Africa's power system?

In the longer term, however, at higher levels of variable generation, flexibility requirements will significantly increase demanding interventions to ensure secure and cost-efficient operation of the South African power system. Energy storage was specifically noted to be highly suitable for this purpose.

Can stationary energy storage solve South Africa's power system challenges?

While the potential of stationary energy storage to address the existing power system challenges, are high in South Africa, the current uptake of the technology is limited to customer-sited, behind-the-meter applications (largely for back up services).

Why is energy storage important in South Africa?

This enables storage to absorb excess capacity on the system when supply exceeds demand. In South Africa’s constrained power system, energy storage can provide backup capacity that can be called on to reduce the extent of loadshedding. As noted earlier, energy storage offers accurate and swift / responsive dispatchability to the system.

Why is battery storage important in South Africa?

In South Africa, battery storage is increasingly seen as a key pillar to help provide grid stability and integrate variable renewables given its ageing coal-fired power fleet and grid.

Is energy storage a business case for South Africa?

This may have greater relevance in competitive markets, but could already have relevance in South Africa’s reserve market (J.M.K.C. Donev et al. 2020). The potential for multiple services and revenue streams improves the business case for energy storage investment and development.

What are the barriers to energy storage in South Africa?

The report noted the main barriers in the region to be lack of regulation supporting the energy storage market, access to affordable financing, political and economic stability, and underdeveloped or aging grid infrastructure. Of particular interest in South Africa is the volume of residential energy storage systems being imported.
