It has been observed that the RE absorption is around 85.32 % on 3rd July, 2029 (i.e. the Maximum VRE day). In order to study the impact of lowering the minimum technical load of coal based plants on RE absorption, a study has been carried out by reducing the minimum technical load of coal plants from 55% to 50%, 45% and 40% on this day. The impact of reducing the minimum technical load on RE absorption on Maximum VRE day is shown in the
During the course of the above analysis, it was observed that RE absorption can be increased with a reduction in minimum technical load, thus increasing flexible operation of thermal power plants. However, this entails investment for technological upgradation in coal-based power plants. An increase of approximately 1.5 % in the RE absorption was observed for every step of 5
% reduction in minimum technical load of coal-based capacity on this day. However, the impact on RE absorption by reducing the minimum technical load of coal-based plants may vary from day to day depending on the coal-based capacity on bar and available RE generation.
