This data page provides case studies of generation losses and deviation penalties due to changes in weather conditions at two solar projects – the 350 MW Bikaner solar plant and the 320 MW Bhadla 2 solar plant. According to the studies, developers are experiencing generation losses due to the twin impacts of foggy and cloudy conditions , and have to pay high deviation settlement mechanism (DSM) penalties due to unpredictable weather conditions.
Assumptions
Plant 1: Bikaner 350 MW, Plant 2: Bhadla-2 320 MW
- Normal generation days considered are along with their average generation during constant/less variable weather conditions.
- Foggy and cloudy days are considered when the weather conditions are quite dynamic and are variable in nature due to foggy or cloudy conditions.
- The clouds are mostly local clouds which are in moving conditions leading to high variability in generation.
