Daylight saving all year round? Evidence from a national experiment

Abstract

We study the effects of staying on daylight saving time (DST) permanently on electricity consumption, generation, and emissions. In October 2016, Turkey chose to stay on DST all year round. Employing alternative identification methods, we find a negligible overall impact on consumption. However, the policy has a strong intra-day distributional effect, increasing consumption in the early morning and reducing it in the late afternoon. This change in the load shape reduced generation by dirtier fossil fuel plants and increased it by cleaner renewable sources that can more easily satisfy peak load generation. Emissions from generation decreased as a result. A large presence of hydropower, which is a reliable provider of energy to the grid in peak times, was crucial to achieve this reduction.
