On April 25, 2023, India recorded an electricity demand peak of 256 gigawatts (GW), surpassing the previous day's 252 GW as extreme heat increased cooling needs. This operational success, with solar energy contributing nearly 22% of the total supply, reflects years of structural improvements in the grid. However, experts caution that India's grid is operating closer to its limits, raising concerns about its ability to meet future demand. Projections indicate that peak demand could rise to 459 GW by 2035-36, necessitating an installed capacity of 1,121 GW. This will require annual capacity additions of approximately 60 GW, significantly above historical averages. To support renewable energy integration, India will need 137,500 circuit kilometers of additional transmission lines and investments of ₹7.9 trillion (approximately $95 billion USD) by 2035-36. Despite vulnerabilities, improvements in forecasting and interstate transmission have enhanced grid performance. Experts emphasize the need for a flexible, resilient, and digitally intelligent power ecosystem to sustain India's energy growth over the next two decades.
