Abstract
Energy markets have so far struggled to encourage flexible household electricity use, partly due to limited consumer price salience. This study examines whether targeted price information affects consumption timing using a randomized controlled trial in Finland involving 1,500 customers on dynamic pricing contracts. Customers had either a spot price contract with hourly prices linked to day-ahead wholesale market prices or a hybrid contract combining fixed and hourly spot pricing. The treatment group received daily messages highlighting the next day’s demand response potential, including high- and low-price hours and a full listing of hourly prices, over a six-month period. Using the trial data, we test whether enhanced price information increases households’ responsiveness to hourly electricity prices, whether effects differ across contract types, and whether responses vary according to price conditions and household characteristics. To evaluate these questions, we compare the price elasticity of electricity demand between the treatment and control groups.
