Manage your energy costs more precisely

Make better use of low-price periods

Gain more transparency into consumption and savings potential

Reduce dependence on expensive peak times

What is a dynamic electricity tariff?

A dynamic electricity tariff means you pay the electricity price currently set by the market. Instead of a fixed price, your consumption is billed based on quarter-hourly exchange prices—an intelligent metering system (Smart Meter) is required.

What is a dynamic electricity tariff?
  • Lower prices when plenty of renewable energy is available on the grid
  • More opportunities to shift consumption into cheaper time windows
  • Greater savings potential for flexible households
  • Especially attractive with a battery, heat pump, or wallbox

Partners Background
LumenHaus

LumenHaus

LumenHaus combines generation, storage, and intelligent control into a holistic energy system.

naturstrom

naturstrom

The company already supplies more than 300,000 households and businesses with 100% clean, locally generated electricity and was recognized in 2025 by leading German media for offering particularly affordable dynamic electricity tariffs.

In an energy world with increasingly volatile electricity prices, it’s becoming more important for households not just to consume energy, but to manage it smartly. That’s exactly where our partnership comes in: together, we make price movements usable and combine them with intelligent energy management for your home—delivering more sustainability, technological intelligence, and economic benefits.

With LumenHaus, a tariff becomes an intelligent energy system

A dynamic electricity tariff reaches its full potential when your home can respond to price movements. That’s exactly what the LumenHaus energy system is built for.

FAQs

What is a dynamic electricity tariff?
A dynamic electricity tariff is an electricity pricing model based on time-varying market prices, such as those from EPEX Spot. Instead of paying one fixed electricity price at all times, the price changes depending on current market conditions.
When renewable generation is high, electricity prices are often lower. When demand rises, prices may increase. A dynamic tariff reflects these real market movements and creates opportunities to use electricity more intelligently.
What is Dynamic+?
Dynamic+ is an integrated energy solution from LumenHaus that combines naturstrom’s dynamic green electricity tariff, naturstrom smart, with an intelligently controlled energy system. In combination with battery storage, the system automatically uses and stores energy during low-price periods, helping to optimize both energy consumption and costs.
This allows you to manage your energy costs more proactively, make better use of favorable market prices, gain greater transparency over your consumption, and reduce your dependence on expensive peak-price periods.
Who benefits most from a dynamic tariff?
Dynamic tariffs are especially attractive for households with flexible electricity demand, such as those using:
• EV chargers
• heat pumps
• battery storage
• solar PV systems
• smart energy devices
The more flexible the household setup, the greater the potential to benefit from lower-price periods.
Do I need a smart meter?
An intelligent metering system (smart meter) is generally a prerequisite for using a dynamic electricity tariff. It enables your electricity consumption to be measured accurately over time and therefore allows precise billing based on the applicable electricity prices at any given time. As part of the implementation, LumenHaus ensures that your home is equipped with a suitable smart meter.
Why is HEMS so important for dynamic tariffs?
A Home Energy Management System (HEMS) makes dynamic tariffs practical and valuable by automatically responding to changing electricity prices.
It can connect price signals with household devices and energy assets such as:
• solar PV
• battery storage
• EV charging
• heat pumps
This allows electricity to be consumed, stored, or shifted more intelligently, without requiring constant manual intervention.
How can a HEMS optimize energy use?
A HEMS continuously evaluates factors such as electricity prices, solar generation, battery status, device availability, and user preferences.
Based on this, it can automatically decide when to:
• charge a battery
• charge an EV
• run a heat pump
• reduce grid imports
• prioritize solar self-consumption
The result is a more automated, convenient, and cost-efficient energy system.
Can I still benefit without solar or battery storage?
Yes. Even without solar PV or battery storage, households can still benefit if they are able to shift some electricity consumption to lower-price periods.
However, the value of a dynamic tariff becomes much stronger when combined with flexible devices and intelligent automation.
Can a dynamic tariff really save money?
It can, but savings depend on the household setup and how much flexibility is available.
The biggest savings potential is typically seen in homes with:
• controllable loads
• EV charging
• heat pumps
• battery storage
• HEMS-based automation
In general, the better the integration between tariff, devices, and automation, the greater the savings potential.
Why are EVs and heat pumps such strong use cases?
EVs and heat pumps are among the most relevant applications because they combine high electricity demand with operational flexibility.
An EV does not need to charge at the same moment it is plugged in. A heat pump can often shift operation within certain comfort limits. With intelligent control, both can be optimized toward lower-cost periods while still meeting user needs.
Is there a risk of high electricity prices?
Electricity prices can rise during short periods of high demand. However, many dynamic tariff models include protective mechanisms, and households with HEMS, solar, or battery storage are much better positioned to avoid expensive periods automatically.
What is the advantage of a one-app solution?
A one-app solution makes dynamic energy management much easier by bringing tariff information, device control, and energy insights together in one place.
This helps users:
• understand when electricity is cheaper
• see how their system is performing
• control devices more easily
• benefit from automation with less complexity
For customers, this means a simpler experience. For providers, it creates a stronger and more engaging energy service.
