Dynamic rates per quarter hour: how does it work?

In the Netherlands, dynamic electricity rates have been set every quarter of an hour since 1 October 2025, instead of every hour. This means that the price of electricity can change more frequently than you may be used to. For households with solar panels, a home battery or a charging station, this presents both challenges and opportunities.

Smart use of solar panels

Due to fluctuating prices, it is even more important to consider when you use electricity or feed it back into the grid. Running appliances when electricity is cheap, or feeding energy back during more expensive quarters, can have a significant impact on your energy bill. Those who adapt to this can get the most out of their solar panels. In combination with a home battery or charging station, you can plan your energy consumption even more intelligently.

Please note: when electricity prices are negative, it is generally not desirable to feed energy back into the grid. Many systems are now smart and can be configured accordingly. With other brands, an additional smart meter or CT clamps may be required.

Home battery for trading or later use

A home battery allows you to store surplus solar energy and use it later when electricity prices are higher. This is often referred to as trading with dynamic rates. It enables you to make optimal use of your solar panels, reduce dependence on the grid and financially benefit from fluctuating quarter-hourly prices.

Smart charging with a charging station

Charging an electric vehicle can now be better aligned with dynamic electricity rates. By charging during cheaper quarter-hour periods or when your solar panels are generating a lot of energy, you can achieve significant savings. A smart charging station makes planning charging times easier and more cost-effective. In combination with a home battery, your car can even be partially charged using previously generated electricity.

More control and peace of mind with Currentt

To make energy management even smarter, OptimaSolar works with Currentt, an advanced LEMS (Local Energy Management System). With Currentt, you can closely monitor the performance of solar panels, home batteries and charging stations and automatically adjust them based on dynamic electricity rates. The system helps optimise energy consumption and ensures you get the most out of every quarter hour in which electricity prices change.

How to get the most out of dynamic rates

Dynamic electricity rates per quarter hour therefore bring both challenges and opportunities. For households with solar panels, a home battery or a charging station, timing has become more important than ever. Smart meters and apps provide insight into current electricity prices, allowing you to operate appliances, batteries and charging stations at the right moments. With the right insights, planning and smart technology, every quarter hour can be used optimally, reducing energy costs and maximising the return on your installation.
