Home for comparison tool
We have an application available that allows consumers to view and compare the various offers available on the market for supplying natural gas and electricity.
It is mainly useful if you are a domestic or SME consumer, since it includes natural gas offers for consumers supplied with up to 4 bar of pressure included within the regulated rates, and electricity offers for medium-voltage consumers, both with and without discrimination of prices based on time slots.
This tool is designed to facilitate comparison of prices and services from natural gas and electricity offers available on the market, in a simple and personalised manner based upon consumption volume and geographic location.
Electricity bill simulator
We have an electricity bill simulator for supply sources adhering to the Voluntary Price for the Small Consumer system (PVPC in Spanish), and last-resort bills for vulnerable consumers.
To use the simulator, just enter the information appearing on your bill: meter reading start and end dates, power, and contracted access rates, consumption recorded during the period in question, and if applicable, whether you are receiving the social assistance credit. The tool will then display the total amount of the bill. .
If you have a smart meter effectively integrated into your system, you must attach the file with your hourly consumption data, which you can download from your distributor's website. At the simulator site you will find a link to a list of distributors and their web addresses.
You can use this tool to check your bill as long as you have a contracted power of 10 kW less and you are being supplied by a major vendor at the “variable PVPC” rate.
