What is the Energy School?

The Energy School is a Naturgy Foundation project that is part of the Energy Vulnerability Plan. The School trains professionals from the social services of public administrations, professionals and volunteers from NGOs and vulnerable people and families.

These travelling sessions address matters related to energy efficiency and optimisation of bills, among others, with the aim of minimising the impact of energy costs on the lives of the most vulnerable people.

The workshops are eminently practical and participatory and the attendees can apply what they learn to their own bills. The School contributes to the Naturgy Foundation’s environmental commitment while driving savings and energy efficiency.


Professional sessions

The three-hour classes are focused on professionals in the Third Sector and social workers. The classes take a deep look at the understanding of bills and responsible energy habits.

  • Social workers in public administrations
  • Social workers in the Third Sector


Due to the state of alarm decreed by the Government for the COVID-19 emergency situation, the school offers virtual sessions on how to manage the energy bill, consumption habits and energy efficiency.

The next sessions are:

  • Friday, May 8 (11am): The electricity bill
  • Thursday, May 14 (11am): Consumption habits
  • Friday, May 22 (11am): Social Bonus
  • Friday, May 29 (11am): Review of current government measures

The contents

What are time use rates?

Time use rates are electricity tariffs where you pay a different price for the energy depending on what time of day you use it.


How can I obtain these tariffs?

Call your trading agent and request the access tariff with time-differentiated pricing. Changing tariff incurs a €9.04 + VAT fee (€10.94).

How to understand your bill

Knowing if your bill is optimised is not as easy as it seems. We recommend focusing on the following concepts: Universal Supply Point Code, contracted power, subsidised rate, access tariff and customer service number. The following images will help you identify where you can find each of these:



The Universal Supply Point Code (CUPS) is the identifier of the home to which the supply is provided. It is a 21-digit code that will be requested when carrying out operations such as giving a meter reading, changing provider, termination, etc.

Contracted power

This is the maximum quantity of electricity energy that can enter your home at any one time, measured in kilowatts (kW). The power that should be contracted depends mainly on the number and use of electrical appliances.

Subsidised Rate

This is an electricity bill discount. It is regulated by the government and aims to protect homes that are considered vulnerable.

Tariff or access fee

The amount that has to be paid to the provider for use of the network. The following access fees are set for powers less than 15kW:

  • Tariff 2.0A (without time-differentiated pricing)
  • Tariff 2.0DHA (with peak and off-peak hours depending on both the hours of operation and tariff)
  • Tariff 2.0DHS (with peak, off-peak and super off-peak hours depending on the hours of operation)

Customer service number

How to optimise your bill

Now you know what the important concepts are for understanding your bill, look at the following steps you can take to optimise it:


What is the Subsidised Rate?

The new Subsidised Rate is a discount on your electricity bill to help customers who are vulnerable and/or at risk of social exclusion.

The subsidy only applies to the habitual residence of customers in the domestic market if they have contracted the Voluntary Price for the Small Consumer (VPSC) and if the conditions outlined here are fulfilled.

Who pays the Subsidised Rate?

The Subsidised Rate is paid by all the electricity supply companies in the market.

In the case of customers at risk of social exclusion, the government pays at least 50% of the bill before applying the subsidy and the remaining amount is paid by the electricity supply companies in the market.
