What funding opportunities are available for grid-scale ESS?

The examples of funding opportunities offered in Australia that encompass, among others, funding for grid-scale ESS include: Australian Renewable Energy Agency (ARENA) introduced Advancing Renewable Energy Programme that grants between AUS$100 000 and AUS$50 million, with applicants expected to at least match the funding being sought.

How does influence affect the development of the ESS market in South Africa?

Influence is assessed in terms of strong, moderate, and limited levels, which are selected on the basis of the stakeholder’s perceived ability and power to influence the development of the ESS market in South Africa given its access to resources and carried roles and responsibility in the electricity supply chain.

Are ESS services worth the cost?

The value of these services is, however, not currently costed or compensated as they form inherently part of the quality of service. Many of the services that ESSs can provide have also been an integral part of operating an extensive portfolio of large, inert power plants in South Africa.

How will ESS be deployed at the bulk generation level?

At the bulk generation level, the deployment of ESS is to be aligned with the IRP 2019 and to be executed through the IPP programme. The IPP programme is implemented by the IPP office, which was formed by the Department of Mineral Resources and Energy (DMRE), National Treasury (NT) and the Development Bank of Southern Africa (DBSA).

What does underinvestment in grid infrastructure mean for South Africa?

Underinvestment in grid infrastructure maintenance, particularly at municipal level in South Africa, means grid infrastructure is aging and therefore becomes less robust and resilient. It also means more events that need to be managed, further placing strain on existing system operations.

Is the current market structure suited to the exploitation of ESS?

The current market structure is not suited to the exploitation of the value proposition of ESS. ESS is a net consumer of electricity and therefore cannot compete with the generation industry on a cost of supply basis.
