STORAGE HEATERS AND ELECTRICAL OFF-PEAK TARIFFS, (WITH TIME DISCRIMINATION-TD)

All heat storage systems, whether dynamic, static, manual, automatic or digital, such as ECOMBI PLUS, have been designed to take full advantage of electrical off-peak tariffs. For that reason, if you have installed or are thinking about installing this type of electrical heating, it is essential to have agreed an electrical off-peak tariff, called “tariff with time discrimination” in Spain.

This type of electrical off-peak tariff, which used to be called the “night tariff”, has two time periods. One lasts for 14 hours, at a reduced price, and is called the OFF-PEAK period. The other lasts for 10 hours, with a price per kWh which has a small surcharge on the standard price. The latter is called the PEAK PERIOD.

When looking at the graphic above, it is important to bear in mind that the “winter schedule” and “summer schedule” will be determined by the change from winter time to summer time we experience in Spain, in October and March, respectively.

In general, significant savings in the electrical tariffs can be achieved thanks to time discrimination. As we just said, in Spain these electrical tariffs include an off-peak period of 14 hours, so if we can shift part of our energy consumption to those times we can achieve savings in the electrical bill of between 30 and 40 per cent.

This does not mean we necessarily need to consume the majority of our domestic energy during those off-peak times of between 10 p.m. and noon, as very often our consumption habits do not allow us to keep 100% to that schedule.
Nevertheless, by transferring certain types of consumption to those times, such as the time we switch on the washing machine, the dishwasher or heat the water, it is possible to achieve considerable savings with those tariffs.
Even if household appliances are connected for 24 hours, as the discount during off-peak times easily exceeds the surcharge during peak times, devices such as a fridge, freezer, wine bar or television will consume for 60% of the day at a fairly cheap price of electricity and for 40% at a price dearer than the standard price.

 

From among the wide range of electrical tariffs available, the one approved and regulated by the government to guarantee citizens the right to an electrical supply at a competitive price is called PVPC (Voluntary Price to the Small Consumer). Previously that tariff was called the Last Resort Tariff (“TUR”).

There are two forms: the normal tariff WITHOUT Time Discrimination, the tariff WITH Time Discrimination and the “Super Off-Peak” tariff reserved for homes with electric cars.

The regulated tariffs can be adopted provided that the agreed capacity is equal to or below 10 kW.

Apart from the regulated tariffs which exist today, we can find numerous offers on the open market for contracts with less than 10 kW and those up to 15 kW or higher, for example the 3.0A tariff for a capacity of more than 15 kW and billing every quarter.

STORAGE HEATERS AND off-peak TARIFFS (TIME DISCRIMINATION)

All heat storage systems charge during the off-peak period, especially during the night, when the cost of electricity is at its cheapest. For that reason, this sort of individual electrical heating requires the contracting of these tariffs with Time Discrimination, whether regulated or on the open market.

We also need to bear in mind that expenditure on heating represents about 60% of home consumption. Consequently, if we transfer the majority of that consumption in heating to Off-Peak hours, we will be paying for our heating at the most economical kW/h. If, in addition, we manage to transfer at least 30% of home consumption to off-peak times, we will be taking optimal advantage of our electrical off-peak tariff.

HOW TO GAIN ACCESS TO THESE off-peak TARIFFS (“WITH TIME DISCRIMINATION”)?

PVPC is only offered by certain electrical companies called “Reference Suppliers”, who are obliged to meet a series of requisites to be certified as such.

 

E.ON Comercializadora de Último Recurso, S.L.
Iberdrola Comercialización de Último Recurso, S.A.U.
Endesa Energía XXI, S.L.U.
Grupo EDP – Hidrocantábrico Energía Último Recurso S.A.U
Gas Natural S.U.R., SDG, S.A.
CHC Comercializador de Referencia S.L.U.,
Empresa de Alumbrado Eléctrico de Ceuta Comercialización de Referencia, S.A.
Teramelcor, S.L.

 

You can contact any of those suppliers to obtain more details about PVPC with TD (Voluntary Price to the Small Consumer with Time Discrimination) regulated by the Government or you can look for another type of tariff on the open market, while always specifying the inclusion of Time Discrimination in your bill. The type of tariff you can contract will always depend on the capacity required by your current installation.

We, at Elnur, recommend that you assess all the electricity offers open to you to find the one best for your installation.

STORAGE HEATERS

We began to design and manufacture storage heaters at Elnur more than 40 years ago. Today, the trademark Gabarrón is a reference for innovation and development in heat storage systems. It now offers the first programmable, digital storage heater in Spain which meets the European Eco-Design Directive: ECOMBI PLUS.
