An electricity tariff is a pricing structure that determines how much consumers pay for their electricity usage. It typically includes a fixed charge and a variable charge based on the amount of electricity consumed, measured in kilowatt-hours (kWh). Tariffs can vary by time of day, encouraging users to consume energy during off-peak hours when rates are lower. Different types of tariffs exist, such as flat-rate tariffs, where the price remains constant, and time-of-use tariffs, which change based on demand. Understanding your electricity tariff can help you manage your energy costs effectively and make informed decisions about your electricity consumption.
