The Eskom Just Energy Transition Project will repurpose the Komati coal power station area with renewable energy and batteries, and create opportunities for local communities. <\/strong><\/p>\n<h2><strong>Shift in the South African energy sector <\/strong><\/h2>\n<p>The Eskom Just Energy Transition Project (EJETP) will finance the decommissioning of the 1 GW Komati coal plant, which is over 56 years old. The last of the fossil-fired units at Komati reached its end of operational life in October 2022. Eskom&rsquo;s power plant infrastructure requires an increase in the deployment of renewable energies<\/p>\n<ul>\n<li>to curb the emission of greenhouse gases: coal generation is still the main electrical power source with approximately 81.4% of the power fed into the grid<\/li>\n<li>to update the ageing and outdated generating fleet<\/li>\n<li>to reduce load shedding: the current power supply gap is estimated at 4-to-6 GW resulting in up to 10 hours load shedding daily<\/li>\n<\/ul>\n<p>By 2030, South Africa plans to retire 12 GW of coal plants and add 18 GW of new wind and solar PV. As a part of this process, The World Bank has recently approved a $497 million concessional loan facility to Eskom for the repurposing of the Komati coal plant. The first phase of the project will include 150MW of photovoltaic and 70MW wind generating capacity, as well as a 150MW Battery Energy Storage System (BESS). Battery storage is seen as a tool for flexibility, benefitting the country&rsquo;s national grid enabling a better power management, such as load levelling or peak demand reduction. Already in their Battery Storage Demonstration Program, Eskom aimed to demonstrate that BESS can be a viable tool to integrate more wind and solar and manage the intermittency of some sites.<\/p>\n<h2><strong>Predictability: Forecasts as a complimentary tool<br \/>\n<\/strong><\/h2>\n<p>A complimentary tool to improve the efficiency and reliability of the electricity with a growing solar and wind capacity, is power forecasting the renewable energy generation. Solar and wind forecasting allows to fulfil several of the national grid operator&rsquo;s objectives, such as high availability, stability and predictable power flow. Depending on the location, some grid codes already contain forecasting requirements, such as South Africa&rsquo;s REIPPP 5 tender. Power controllability is made certain by pre-defined minimum and maximum ramp rates, which is why forecasts are essential to warrant compliance with these rules and avoid penalties.
