How to choose the best electricity tariff for you?

How much power should I contract?

Before switching tariffs, you must know your consumption and the power you have contracted. With this information, you can determine the best balance between savings and comfort.

For example, if you use electric heating, the oven, and the dryer simultaneously because you're not home often, you’ll need higher power to avoid tripping the breaker.

If you need more information, we explain everything you need to know about the power that best suits you—from how much you need to what electrical power actually is.

How many kWh do I consume per year?

Understanding your household’s energy use is crucial for making the right decision and maximising savings. It’s worth taking a moment to check when and how much electricity you use.

Checking this is easy if you’re an Endesa customer: simply register on our website. If you’ve already registered, just log into your Customer Area with your username and password to review your consumption—annually, monthly, daily, or even hourly! We provide all the information you need in a simple, fast, and convenient way to help you make informed decisions.

Analyse your expense

Reviewing your bill’s cost breakdown—from energy consumption to contracted power—is key to identifying saving opportunities and optimising your energy budget.

• Energy cost (€/kWh): the most significant factor in your bill. Find a tariff with a competitive price to maximise your savings. This appears as an ‘energy charge’ on your bill.

• Contracted power cost (€/kW): displayed as kW*€/kW*No. of days (power term). Includes two pricing bands: peak (more expensive due to high-demand hours) and off-peak (more affordable during low-demand hours).
• Discounts and promotions: lastly, promotions play a crucial role in savings. Generally, they not only grant percentage discounts on energy charges but also direct bill reductions or free consumption periods.

Review additional charges

Some attractive tariffs come with extra costs that could make you pay more than necessary. Scan every detail of your bill to find additional services or charges that might impact your monthly expense.

Marketing margin: some providers include a fee for energy management and supply that adds no real value to customers. At Endesa, we never include this charge, although many other energy providers do.

Maintenance services: some tariffs include maintenance fees for appliances, repairs, or inspections. While useful, it’s important to assess if they really fit your needs.

Loyalty programmes

More and more providers offer loyalty programmes, allowing customers to enjoy great perks. The biggest benefit is undoubtedly savings on electricity and gas bills, but there are also advantages on other products and services through partner companies.

At Endesa, we have Para Ti, our free loyalty programme where you can:

• Earn points for signing up, activating digital billing, contracting a new supply, achieving consumption goals, or staying with us.
• Redeem points for discounts on your electricity and gas bills—the choice is yours!
• Enjoy additional benefits like discounts with partner companies and exclusive draws.

Which is better: a fixed or variable tariff?

Well, like most things, it depends on what you prefer.

A variable tariff follows the wholesale market, which is unpredictable. Electricity prices change hourly and are only known a day in advance. There are 24 different prices daily—sounds a bit crazy, right? The good thing is that you don’t have to worry about anything; your smart meter records your consumption and applies the corresponding price variations. The downside? You have very little control over your expenses.

For this reason, many people prefer to forget about price fluctuations and enjoy a stable, low fixed tariff throughout the year—one that, of course, adapts to their needs. Within fixed tariffs, you can also take advantage of time-of-use plans, allowing you to benefit from better prices during the times that suit you best.

Fixed-price tariff per kWh: One Luz

You don’t like complications, paperwork is a hassle, and you hate waiting in line as much as you hate holding music. You want things to be simple and fast—very fast. You want everything online.

If this sounds like you, One Luz is your option. It guarantees a stable price per kWh and is specifically designed so you don’t have to worry about peak hours.

It’s so affordable that it doesn’t need to dazzle you with discounts. The electricity tariff that gets straight to the point: 100% digital. This way, you can manage everything anytime, anywhere. No more long conversations with call centre agents—now everything happens with just a click.

No need to stress about when you use the most electricity; the price stays the same all the time. No tricks, no long-term commitments, no penalties. 

Additionally, if you’d like to add a maintenance service, we offer Protección 360 plus, which gives you the following benefits:

• 24/7 year-round support for your electrical installation.
• Appliance repair, locksmith, plumbing, and glass repair services.
• Bill payment protection insurance for your electricity bills.

Time-of-use tariff: One Luz 3 Periods

You identify with the One Luz profile, but with a twist: you’re a night owl who comes to life gradually.

For you, there’s One Luz 3 Periods. This time-of-use tariff allows you to use electricity at a much lower price at night and a moderate price between 8:00-10:00 and 14:00-18:00.

This tariff keeps all the advantages of One Luz while adding time-based savings.

Time-of-use tariff: Tempo Happy

You know exactly how much energy you consume and when you consume it. You dislike being forced into a predefined schedule. You are unique—your circumstances matter, and if your partner doesn’t understand that, well, that’s their problem.

Don’t overthink it—your ideal tariff is Tempo Happy, which lets you choose between two flexible options:

• Tempo Happy 2 Hours: choose two hours each day when you won’t pay for the energy consumed.
• Tempo Happy Day: choose one day per week when your electricity is free.

You can switch between options at any time or adjust them to fit your lifestyle changes. This tariff listens to you and understands you; if you use it wisely (at least 25% of your consumption in ‘happy hours’), you’ll save every day.

And what about the rest of the hours? Are they sad hours with no love? Not at all—they come with a stable price and no surprises.

And like any healthy relationship, there are no strings attached—no commitment required.

More than a flat tariff: Endesa Única

Peace of mind is more than just a flat tariff. You don’t want to be tied to specific hours, nor do you want a complicated deal. You want stability and security—that’s why you choose Única.

With Endesa Única, you’ll never have any surprises—you’ll always pay the same. It’s as simple as that.

We know the market is full of options. It’s normal to ask, ‘Which one should I choose?’ ‘How much power should I contract?’ or ‘How many kWh do I consume per year?’ But wait... ‘What tariff do I have now?’
