The demand plot of UP State for 24th Oct 2019 shows the impact of 'Lighting Load' on Demand with sunset, bolstered by Diwali's Decorative Lighting Load. UP has one of the steepest evening peak demand of all States, with around 50% jump in just 2 hours (5pm to 7 pm). Such steep demand due to lighting load calls for ramping of power plants @700 MW every 15-minute in the 2-hour span, which ironically fizzled out almost at half the 'ramp-up' rate post 7 pm!
