This study evaluates hybrid Wind-Solar-BESS configurations for Tamil Nadu, India, under a representative 100 MW, 4-hour peak demand block (two hours each in morning and evening) using the Annual Peak-Hour Demand Fulfilment Ratio (DFR) and SECI’s (Solar Energy Corporation of India) >=90% DFR compliance criterion as reliability metrics. Long-term generation profiles (2005-2024) from ERA5 reanalysis were used to simulate 0-200 MW capacity combinations for each component. The results show that storage is indispensable: without BESS, no configuration achieved SECI compliance, and DFR remained below 40%. Adding storage progressively improved performance, with mean DFR reaching ~85% at 200 MWh BESS. Solar combined with storage achieved up to ~60% DFR, while inclusion of wind raised reliability further up to ~85% and expanded compliance to ~44% of grid points under the 200:200:200 configuration. Spatial analysis revealed compliance concentrated in wind-rich western, southern, and coastal districts. Sensitivity analysis under +/-10% resource variation confirmed the robustness of these outcomes. Overall, targeted deployment of Wind-Solar-BESS systems, emphasizing wind-rich regions and optimal storage sizing, represents the most effective pathway toward SECI-aligned reliability in Tamil Nadu.
