In a recent webinar hosted by the South African Independent Power Producer Association (SAIPPA), attended by industry leaders and energy sector stakeholders, Joanne Calitz, Team Lead: Energy Systems Optimisation at ENERTRAG South Africa, delivered a comprehensive presentation entitled, “Important considerations for the IRP in South Africa: Insights from an Energy Modelling perspective.” Calitz’s presentation was a highlight, offering a nuanced understanding of the role of capacity expansion models and the imperative for openness and transparency in energy modelling.
Key highlights from Calitz’s presentation included the necessity of balancing detailed operational insights with the computational complexities inherent in energy modelling. ENERTRAG South Africa advocates for the adoption of open-source models and data to ensure the IRP’s development process is accessible, transparent, and conducive to peer review and collaboration.
The discussion on temporal and spatial resolution in modelling underscored the importance of accurately capturing renewable energy contributions and demand patterns to ensure a reliable and efficient energy system. Calitz also emphasized the need for realistic modelling constraints that accurately mirror the operational and environmental limitations faced by the energy sector.
One of the critical areas addressed was the strategies to minimize unserved energy and load shedding, highlighting the economic and operational considerations in managing curtailment within the power system. This aspect of the presentation sparked significant interest among attendees, pointing to the complex balancing act required in planning for the nation’s energy future.
The presentation concluded with a strong call to action for comprehensive and transparent reporting of IRP results. Calitz stressed the importance of detailed analyses and clear communication in shaping energy policy and guiding strategic decisions.
In closing, Calitz confirmed ENERTRAG South Africa’s commitment to contributing to South Africa’s energy sector through expert insights and advocacy for transparent, data-driven approaches to energy planning. The webinar’s success and the positive reception of Calitz’s presentation underscore the critical role of informed dialogue and expert analysis in navigating the challenges and opportunities in South Africa’s energy landscape.
