The Tempo Happy tariff from Endesa S.A. turns the quiet hum of a dishwasher at 10 p.m. into something like a small household victory, because for two chosen hours a day the meter simply stops counting. It is a long-running plan in Spain that rewards families for shifting their heavy-use appliances. In practice, it feels like gamifying the power bill without changing the wiring at home.

How Tempo Happy works

Tempo Happy is a residential electricity tariff that offers customers two daily hours in which consumption is billed at zero, while the remaining 22 hours are charged at a conventional rate. The customer selects those free hours in advance and can later adjust them if their routine changes. For many households, those slots line up with evening laundry runs, cooking, or electric vehicle charging.

Endesa positions Tempo Happy for Spanish households that want more control over their bill without diving into complex time-of-use charts or installing extra hardware. The plan is available to customers with standard low-voltage residential contracts and is structured to keep the base conditions similar to the company’s mainstream fixed and indexed tariffs, but with the twist of free hours acting as a daily anchor.

Everyday use in the home

In a typical flat in Madrid, Tempo Happy users see the benefit most clearly when they stack their high-load tasks into the chosen window: the washing machine churns, the oven runs, and a plug-in hybrid charges all while the digital meter’s reading will not translate into extra cost for that period. The rest of the day feels like a normal flat-rate plan, so there is no constant need to watch the clock, just a habit of clustering.

Endesa’s retail chief, José Bogas, has described these kinds of tariffs as a bridge between traditional fixed pricing and smarter, more dynamic contracts, giving households a first taste of time-based optimization without heavy jargon or the need to own a rooftop solar array. Tempo Happy thus sits as an accessible step for customers who are curious about flexible pricing but still value predictability on most of their bill.

What the tariff offers

Tempo Happy’s main attraction is the two hours of zero-cost consumption, which are structurally built into the contract rather than functioning as promotional discounts that vanish after a few months. During those hours, the kWh price is effectively set to zero under the agreed conditions, and the rest of the day follows a defined rate per kilowatt-hour that Endesa publishes for the tariff segment.

The contract typically includes standard grid access fees and taxes that apply to Spanish electricity bills, so the customer still sees regulated components and VAT in their invoice, but the consumption line for the chosen free hours is marked as without charge. That design becomes particularly compelling for households with predictable peaks, such as daily evening cooking or a fixed charging routine for an electric vehicle.

Where Tempo Happy falls short

Tempo Happy is not the cheapest option for every profile, especially for customers who consume little power in concentrated bursts and instead spread their usage evenly across the day. For those users, a simple low fixed-rate or a fully indexed tariff might sometimes bring a lower annual bill, depending on wholesale market movements.

Another limitation is that the tariff still lives fully inside Spain’s regulatory framework, which means the zero-cost hours apply only to the energy component under the contract and do not bypass other regulated charges. Customers who expect an ultra-low bill by putting everything into those two hours may be sobered when they see the remaining fixed elements on their invoice.

Customer profile and strategy

Tempo Happy is designed for Spanish households with enough flexibility to move some heavy tasks, such as laundry and dishwashing, into specific daily windows. Families with young children, who may run multiple loads of clothing and dishes, can often adapt evening routines to match the free hours while keeping comfort intact.

The tariff also finds a niche among small home offices and remote workers who can schedule their device charging or even some heating or cooling cycles around the chosen window, as long as they do not need full-day intensive use. Endesa uses such targeted offers to differentiate itself in Spain’s competitive liberalized electricity market, where utilities compete on tariffs, digital tools and customer service rather than on commodity alone.
