This peak load is forcing greater reliance on coal and diesel power plants to maintain supply. Nighttime generation is currently dominated by a 900 MW coal plant and around 1,000 MW of diesel capacity, The Star reports.At the same time, Sri Lanka produces surplus solar power during the day but lacks large-scale battery storage to shift this energy into the evening. Authorities are thus encouraging daytime charging and considering time-based tariffs to reduce nighttime demand.The policy comes amid wider energy constraints linked to fuel supply disruptions. With EV uptake increasing—more than 10 per cent of recent vehicle imports are fully electric—the government is seeking to better align charging behaviour with available renewable generation.thestar.com
