Endesa Libre Luz 3: 3-Band tariff with a fixed price for each period

The Endesa One Luz 3 tariff is an electricity tariff with three distinct time periods, each with a fixed price per kWh. Unlike single-price 24-hour tariffs, here the cost of electricity depends on the band in which you consume it, although the prices don’t change from day to day and aren’t tied to the hourly wholesale market.

It’s designed for users who can organise their consumption around the time bands and want to take advantage of different prices per period without taking on the volatility of an indexed tariff.

How does Endesa’s 3-band tariff work?

This tariff divides the day into three time periods (peak, standard and off-peak), each with its own fixed price:

• Each section has a fixed price; it does not vary from hour to hour.
• The cost of kWh depends on the period in which consumption is made.
• The timetables for the sections are regulated and are the same for all transport operators.
• It enables you to optimise your electricity costs by concentrating your consumption during the cheapest periods.

There is no exposure to daily market rises, but there are clear differences between trading sessions.

Who is this tariff a good option for?

This tariff is particularly well suited if:

• You can time part of your consumption to specific times of day.
• You use energy-intensive household appliances (washing machine, dishwasher, electric water heater, tumble dryer or charging an electric vehicle).
• Do you use more electricity at night or in the early hours of the morning?
• You are looking for potential savings whilst keeping prices stable across each price band.
• You understand how time periods work and make active use of them.

It is a middle ground between a 24-hour flat rate and an index-linked tariff.

Key advantages of the Endesa One Luz 3 tariff

Fixed price for each period

Each section has a fixed price, which provides predictability within each time slot.

Potential savings based on habits

If you concentrate your consumption during off-peak hours, the average cost may be lower than that of a 24-hour flat-rate tariff.

Lower exposure to market volatility

It does not depend on the hourly price on the wholesale market, thereby reducing uncertainty.

Suitable for households with flexible energy consumption

It works well when there is a genuine ability to shift consumption to cheaper time slots.

Points to bear in mind before signing a contract

Requires attention to timetables

If you mainly use electricity during peak hours, it may work out more expensive than a 24-hour flat-rate tariff.

More complex than a 24-hour tariff

It is important to understand the time slots and adapt your habits to make the most of them.
