Most households are familiar with the fact that the electricity price is set once a year - and then applies regardless of the time of day or market events. However, this is no longer the reality on the electricity exchange. Prices there fluctuate at 15-minute intervals, depending on supply and demand. Tibber utilises precisely this mechanism and makes it accessible to end customers. In combination with KOSTAL inverters and storage systems, a system is created that actively optimises electricity costs - automatically and transparently.

Tibber buys electricity directly on the exchange and passes on price fluctuations 1:1 to its customers. Users can see the prices in advance via the app and can adjust their consumption behaviour accordingly.

Even better: the app takes over the optimisation automatically. This means that devices such as electric cars or heat pumps can be operated precisely during the cheapest hours - without the customer having to intervene.

KOSTAL supplies the technology that makes flexible consumption possible in the first place. The inverter ensures that PV electricity is prioritised for use. The storage system buffers energy and can be charged or discharged when it makes economic sense.
In combination with Tibber, this means that surplus solar power is utilised in the storage system or directly in the house:

• Surplus solar power is used in the storage system or directly in the house.
• When electricity exchange prices are low, the storage system can also be charged at a favourable price.
• When prices are high, Tibber automatically reduces the amount of electricity drawn from the grid and utilises stored energy.

This creates an intelligent interplay that reduces both costs and CO₂ emissions.

The combination of KOSTAL inverters and Tibber dynamic tariffs brings several advantages:

• Noticeable cost savings: The electricity is always used at the most favourable times.
• More self-consumption: PV electricity remains the first choice, grid electricity is only used as a supplement and in a targeted manner.
• Transparency: Prices and consumption are visible at all times in the app.
• Flexibility: The system reacts automatically to price fluctuations without the customer having to constantly intervene.
• Sustainability: Flexibilisation makes better use of the proportion of renewable energy in the grid.

For installers, dynamic tariffs are a strong argument in sales talks:

• Added value for customers: A modern energy system that not only generates electricity, but also buys it cleverly.
• Cross-selling potential: Storage systems and wallboxes are particularly interesting if they can utilise dynamic tariffs.
• Image as an innovator: Offering customers this solution positions you as a pioneer for smart energy.
• Simple implementation: Thanks to Modbus integration and Tibber Bridge, setup is straightforward.

This allows installers to expand their portfolio and clearly stand out from the competition.

A typical day could look like this:

• In the morning: The electricity price is high. Tibber prioritises the storage system and PV electricity for household needs.
• Midday: The sun is shining and the PV system is producing a surplus. The storage system is fully charged.
• Afternoon: Electricity prices fall sharply. Tibber uses the window to charge the electric car cheaply.
• Evening: The grid price rises again. The storage system supplies the house - grid electricity is avoided.
• At night: Tibber recognises another favourable time window and optionally charges the battery for the next day.

The result: minimum electricity costs with maximum convenience.

The integration of dynamic tariffs is still in its infancy. In future, even more consumers will be integrated - from heat pumps to air conditioning systems. At the same time, participation in virtual power plants (VPP) will enable households to actively contribute to grid stability and be remunerated for this.

With KOSTAL as the hardware partner and Tibber as the software platform, a system is being created that not only brings benefits for the individual, but also strengthens the big picture: the energy transition.

The combination of KOSTAL inverters and Tibber dynamic tariffs makes households more independent, flexible and cost-efficient. End customers save money and increase their self-sufficiency. Installers gain new business opportunities and a strong argument in consultations.

Dynamic electricity tariffs are the future - and with KOSTAL & Tibber, the future starts today.
