The Energy Council of South Africa (ECSA), in partnership with power market simulation software developer Energy Exemplar, has launched the cloud-based Energy Data and Modelling for South Africa (EDMSA).
The platform will facilitate collaborative development and analysis of models and scenarios, incorporating key assumptions to enhance national capability in energy modelling, said James Mackay, CEO of ECSA, during the webinar launch of the new platform on August 28. “It fosters impartial and fact-based discussions across the energy spectrum, which is crucial for well-informed decisions about the country’s energy priorities.”
Using Energy Exemplar’s PLEXOS cloud technology, the platform offers advanced modelling for South Africa’s power system, focusing on capacity, energy adequacy and integration of renewables. “The model provides a granular, hourly-level analysis of the South African power system, considering transmission constraints and the flexibility of assets,” says David Robertson, Vice President of Solutions at Energy Exemplar.
“It's essential to address capacity adequacy to ensure that there is sufficient installed capacity to meet peak demand in our energy model, particularly as South Africa increases its reliance on renewable energy sources,” he added.
“We also need to account for system limitations such as transmission constraints and asset flexibility. We cannot assume that assets can be easily started and stopped on demand; they must be able to adapt to the variability of renewable energy generation. Using PLEXOS can help us develop a comprehensive model for the South African power system, offering detailed insights on an hourly basis.”
Energy transition efforts
The EDMSA platform originated from efforts put into the energy transition roadmap. “It highlighted the need for a transparent platform for accessing data, modelling scenarios and fostering collaboration to address any blind spots and gaps,” Mackay said. The platform is designed to support a 10-year implementation programme for an integrated energy transition plan.
Mackay acknowledged progress made, noting stabilisation of the grid and current uninterrupted energy supply. However, he pointed out associated costs and potential emissions concerns in the medium to long term. “While we celebrate the end of load shedding and improvements in operational reliability, there are inherent risks and complexities in the energy transition.”
The EDMSA will operate independently, encouraging engagement by various stakeholders to refine the platform, Mackay said. “The platform will provide stakeholders with the tools they need to ask the right questions and support the achievement of national energy priorities. They will be equipped to ask the right questions as we strive to develop the best solution for South Africa’s energy transition.”
