The document discusses three solutions to implement daylight saving time in India: advancing the North-Eastern region by 1 hour all year, advancing that region 1 hour ahead of Indian Standard Time year-round, or implementing a 1-hour daylight saving time for the rest of India in summer months. It estimates the potential energy savings in summer months for some states under the third solution, with Madhya Pradesh seeing the largest savings at 0.22% or around 100,000 MWh. The document also notes it will address counterarguments to the proposed solutions.
