KSTAR: Energy management made easy and efficient

Modern society is looking for ways to use renewable energy sources efficiently. One of these is undoubtedly solar radiation. It is an inexhaustible source of energy. That is why photovoltaics are becoming increasingly popular.

It is a very environmentally friendly solution that allows you to obtain heat, hot water or charge your electric car. However, it is not always possible to consume all the energy at a given moment, resulting in a surplus.

The best way to use surplus solar energy is to store it for later consumption. Currently, there are two options available: virtual and physical batteries.

Virtual batteries
A virtual battery is a battery that does not physically exist. Your surplus solar energy automatically ‘flows’ back into the grid via your smart meter. As the provider of the virtual battery service, your electricity supplier monitors these flows via online data from your smart meter and records them in its business systems.

However, once it has passed through the smart meter, the ‘stored’ solar electricity is physically merged with the other electricity in the grid and is consumed almost immediately by other electricity consumers. Therefore, only a billing record exists.

Storing solar surpluses in a virtual battery usually costs nothing, but when you want to consume them, you pay all distribution charges except for the electricity itself, known as power charges. These charges account for approximately 67% of the total price of electricity for households and 58% for businesses.

Physical batteries and their advantages
A physical battery is installed at the point of solar energy production, near the distribution box. It is mostly used to store excess solar energy or night-time energy.

The advantages of a physical battery include a one-off investment in its purchase and no additional monthly fees. However, you can significantly reduce this investment thanks to subsidies that often apply to the purchase of ESS (energy storage systems).

You can even earn money with a physical battery by providing regulatory services to stabilise the grid.

In addition, the battery can serve as a backup power source in the event of a power outage.
