What is the bi-hourly tariff? Are there any advantages to subscribing to this type of tariff? How to choose the right option? How to maximize savings with this type of tariff?
Choosing the right tariff option and changing small energy usage habits could represent significant savings on your electricity bill.
WHAT TYPES OF RATES ARE AVAILABLE FOR THE CONSUMER?
Currently, residential consumers have access to three types of tariffs:
- In the simple tariff, the consumer pays electricity at the same price for all hours of the day.
- In the bi-hourly tariff, the consumer pays electricity at two different prices, for two corresponding hourly consumption periods: the empty hours period, in which energy has a lower cost; and the period of hours of Fora de Vazio, in which energy has a higher cost.
- The three-hour tariff is similar to the two-hour tariff, but it has three hourly consumption periods with different prices: the empty hour period, in which energy has a lower cost, the full hour period, in which the energy has an intermediate cost and the peak hour period, in which energy has a higher cost.
WHAT ARE THE HOURS AND HOW ARE THE HOURS DISCREADED?
The hourly periods for the delivery of electricity to final customers are provided for in Articles 24 and 31 of the Electric Sector Tariff Regulation, of ERSE, and differ in two cycles: the weekly cycle and the daily cycle.
In the weekly cycle there is a distinction between working days and Saturday and Sundays. On the other hand, in the daily cycle the hourly periods are the same for all days of the year.
Hourly periods in Mainland Portugal are determined taking into account the evolution of the country’s load diagram throughout the year.
The costs associated with each hourly period are related to the demand for electricity in the national market. Thus, the Empty period corresponds to the times when the demand for electricity is reduced, the Flood period corresponds to times when there is an intermediate demand for electricity, and the Peak period, corresponds to times when there is a demand highest amount of electrical energy.
The period of Out of Empty corresponds to an aggregation of the Full and Peak periods. In bi-hourly and tri-hourly rates, the Emptyperiod aggregates the normal Empty and Super Emptyhourly periods.
WHAT ARE THE DIFFERENCES BETWEEN THE TWO CYCLES?
The daily cycle and the weekly cycle differ both in the way the hourly periods are broken down on a weekly basis and in their duration.
Distributed in the same way for the seven days, including 7 hours a day at night.
During the week, the night time has a shorter empty period, so that most empty hours occur during the weekend, that is, Saturday afternoon and throughout the day on Sunday.
Consumers should analyze their electricity consumption habits and understand whether to opt for the daily cycle or the weekly cycle.
