​Building bridges: On India’s solar generation, battery storage

India's record peak demand saw solar meet 21.5% of afternoon load, highlighting its potential. However, solar's overall daily contribution was only 10.8%, negligible after sunset. This gap between capacity and generation is due to insufficient battery storage, causing power curtailment and public cost. A drier summer will increase daytime demand. While battery tariffs are falling, operational storage is minimal. The author emphasizes urgent commissioning of co-located storage with solar, stating solar capacity without storage is a "half-built bridge."
