A power grid has to perform a continuous balancing act. At every moment, the total electricity being produced (the ‘generation’) must match the total being consumed (the ‘load’). For most of its history, the central worry about the grid was whether there was enough generation capacity. Over the last decade, India has answered that question emphatically. It added generating capacity at remarkable speed, and built a large fleet of solar power, rising to over 157 GW by May 20261.
