Your home is becoming smarter.

Your energy tariff should too.

10s Energy gives energy-aware households, EV owners, prosumers, and businesses early access to electricity pricing that moves with the real market — in 15-minute intervals.

Instead of being locked into a tariff designed for the average customer, you can start seeing when electricity is cheapest, when prices spike, and when the market creates opportunities to shift, automate, and potentially save.

Energy consumption has changed. Energy tariffs haven’t.

Important disclaimer

img-14

Homes are becoming high-energy systems

Electric vehicles, heat pumps, solar panels, batteries, and smart devices are turning homes into dynamic, high-consumption environments.

Energy is no longer just “on or off” — it’s when, how, and how much.

img-14

Tariffs are still built for the old world

Most energy products are fixed, averaged, and designed for predictable usage patterns.

They simplify complexity — but in doing so, they remove your ability to respond to real market conditions.

img-14

You carry the cost of that mismatch

When tariffs don’t reflect how energy actually works, you lose flexibility, visibility, and potential savings.

The system is optimised for the provider — not for how you actually consume energy.

Access electricity prices as they really move.

See real-time prices

View electricity prices in 15-minute intervals based on real wholesale market data.

Understand when to use energy

Know when electricity is cheapest or most expensive, so you can make informed decisions.

Shift and optimise usage

Move flexible consumption—like EV charging or appliances—away from peak pricing periods.

Turn volatility into advantage

Take advantage of price drops and potential negative pricing events instead of being exposed to them.

Built for people who can actually benefit from dynamic pricing.

10s Energy is built for customers with flexible or meaningful electricity consumption, including:

9

EV owners

Charge when electricity prices are low, instead of defaulting to expensive peak periods.

9

Solar households

Understand how your consumption interacts with the wider energy market.

9

Heat pump users

Shift or optimise usage around pricing signals where possible.

9

Prosumers and high-consumption households

Turn complexity into an advantage instead of being penalised by one-size-fits-all tariffs.

Most energy companies are built for scale. They design products for the largest possible market, smooth out the complexity, and price risk into contracts that protect their margins.

10s Energy is built differently.

We are a technology-first energy company creating products for customers whose needs are real, valuable, and underserved — even if they do not yet fit the mass-market playbook.

We believe the energy transition will not only be won by the biggest incumbents. It will be won in the gaps: by companies willing to build for complexity, explain what is happening in the grid, and share the financial upside with the people flexible enough to create it.

Frequently asked questions

01. Is 10s Energy available now?

Not yet. We are currently collecting earlybird signups ahead of launch.

02. What does early access mean?

It means you can register your interest now and be among the first to hear when the product becomes available.

03. Am I committing to anything by signing up?

No. Earlybird signup is free and non-binding. 

04. What is 15-minute electricity pricing?

It means electricity prices can change in short intervals based on real market conditions. This creates opportunities for customers who can shift or optimise when they use electricity.

05. Can this really save me money?

Potentially, yes — especially if you have flexible electricity usage, such as EV charging, heat pump consumption, battery storage, or business operations that can be shifted. However, savings are not guaranteed and depend on your usage and market conditions.

06. What kind of customers is this for?

10s Energy is best suited to energy-aware households, EV owners, prosumers, heat pump users, solar households, and businesses with meaningful or flexible electricity consumption.

07. Is the calculator a final quote?

No. The calculator provides an estimate based on real data, but results are indicative and subject to change before launch.

I've had solar for four years. I had no idea I was leaving this much money on the table. The first quarter on 10s more than covered the prosument tariff.

Bart V. Ghent
8 kWp, Flanders

My EV now charges almost entirely during my solar peak or during negative-price windows. The combination is ridiculous. I genuinely feel like I'm gaming the system.

Nathalie D.
Leuven, 6 kWp + EV

Set it up on a Saturday morning. Didn't touch it again. I check the dashboard sometimes just because it's satisfying to watch.

Not included in any figure above

Neither the standard dynamic nor the 10s Smart costs include the supplier's commercial margin. The fixed market reference already embeds a typical margin — the dynamic figures do not.

Belgian dynamic tariff providers typically charge €0.015–0.025/kWh above spot plus an annual fee of approximately €50–80/yr (Luminus: €0.021/kWh + €75/yr; Engie: spot × coefficient + fixed constant).
