It is essential for us to make the transition to renewable energy sources if we are to meet the challenges that climate change is posing. In this context, domestic batteries provide an effective solution in the face of the fluctuating nature of these energies.
With the need to reduce CO2 emissions, many countries are encouraging the use of renewable energy such as solar and wind power. However, the intermittent nature of these energy sources pose a problem in ensuring continuity of supply.
As a result, domestic batteries are emerging as a solution that allows us to store electricity when generation levels are higher than current demand, for use later on.
Contributing to the stability of the grid
With the rise in the generation of renewable energy, managing the variability of this production has become a major issue. Domestic batteries can help us to balance the load on the grid by storing excess energy and releasing it during peaks in demand.
Minimising injection
Solar panels, for example, allow you to generate and consume your own energy. But when the generation is too high compared to your household's needs, the excess electricity is sent to the grid. Your energy supplier then pays you per kWh injected. However, this remuneration is quite low compared to the price of the electricity extracted from the grid.
Maximising self-consumption
This is why increasing numbers of households with solar panels are opting for a domestic battery. Depending on its capacity, this device allows you to store all or part of the excess energy generated by your panels. The energy can be returned when production is lower, or non-existent, thus maximising the use of your solar installations.
Optimising your energy costs
The battery can also be supplied with energy from the electricity grid, known as "grey energy". By allowing you to store energy when it is cheaper, and use it when it is more expensive, domestic batteries can help to reduce your energy costs.
Making the most of market fluctuations
In the near future, and if your supplier offers it to you, you'll be able to opt for electricity contracts with a dynamic rate. This means that the hourly price of energy will vary in line with the rates on the energy market. As a result, you'll be able to recharge your battery when the rates are at their lowest, or reuse the energy when the prices are higher.
Good to know
If you install a battery on your home network, you will have to replace your meter with a smart meter, whether or not you have solar panels. If you already have solar panels, you should already have a smart meter. If you're having your battery installed at the same time as the panels, the meter you have will be replaced with a smart meter, if necessary.
