What has changed with regard to what we pay for power?
First and foremost, you now pay less for the power term. Small consumers used to pay 38 euros per kW per year for the contracted power term, while now that price is 30 euros per kW.
Now, there is also the possibility of contracting two different powers: One for the off-peak period and one for the rest of the day. This will enable you to contract more power in the cheapest period and take advantage of those hours to programme consumption such as charging an electric car or heating and hot water systems by accumulation.
Who is most affected by the change?
The change affects all customers, but the impact will depend on when customers consume energy. If a domestic customer already used more electricity in the hours that are now within the off-peak period, the effect on the bill will certainly be positive.
Small businesses, which have less flexibility than a family to adapt their consumption to the cheapest hours, may well see their bills increase.
In the case of customers who concentrate their consumption at peak times for professional or other reasons, it is always advisable for them to review with their retailer what the most appropriate conditions for them would be and to ask for advice on adapting the contracted power to their consumption habits.
What about customers who already had discrimination by time band before?
The previous tariff with time-band discrimination included 14 off-peak hours every day of the year (from 11pm to 1pm in summer and from 10pm to 12 midday in winter). Now, part of this time band is peak or standard so, if consumption is concentrated in those hours, they will pay more on the bill.
There is no doubt that clients who are able to adapt their consumption to the off-peak hours, between 12 midnight and 8am and on weekends, will benefit.
What consumes the most electricity in a home or business?
Domestic appliances account for 55.2% of residential electricity consumption in Spain according to the IDAE (Spanish Institute for Diversification and Energy Saving), so this is one area where action can betaken to control energy expenditure.
First of all, it is important to have efficient or low-consumption domestic appliances. This is defined by energy categories, which have also changed recently. The most efficient is category A (formerly A+++). For example, a highly efficient refrigerator consumes three or four times less than an old refrigerator.
Furthermore, if you bear in mind which appliances consume the most, you can plan to use them in the cheapest hours.
