BESS battery storage – smart energy management with Norelco Oy’s solutions

The energy transition is here – and at its core are intelligent energy storage solutions. One of the key technologies driving this change is BESS (Battery Energy Storage System). BESS enables the efficient use of renewable energy, balancing of the power grid, and optimization of energy costs. But how can we ensure that the system is safe, scalable, and long-lasting? The answer lies with a Finnish expert: Norelco Oy.

Energy when you need it – battery storage is revolutionizing electricity use

The recent energy crisis and sharp fluctuations in electricity prices have increased interest in battery energy storage. The idea is simple: charge the batteries when electricity is cheap and use the stored energy when production is insufficient – for example, during calm winter days, which are common in Finland. In practice, batteries can help smooth out price spikes, especially with the upcoming quarter-hour pricing model.

Solar and wind power generate electricity intermittently. At the same time, hourly prices on the electricity market can vary dramatically. This creates a need for balancing energy, which battery systems can provide. They store electricity when it’s affordable and discharge it into the grid when prices are high or production is low. These systems are connected to the distribution network, and consumers can also install them at home.

Battery technology as part of grid stability

Battery solutions not only serve consumers but also play a crucial role in stabilizing the entire power grid. In Finland, the transmission system operator Fingrid uses battery storage in frequency reserve markets. Batteries are connected to key nodes in regional networks, where they can balance consumption and production peaks and support the local distribution grid.

Alongside solar and wind power, the battery energy storage market is growing rapidly. While batteries don’t generate electricity themselves, they enable more efficient use of renewable energy. The adoption of batteries has been accelerated by technological advancements and falling prices.

Battery solutions are increasingly being built not only into transmission and distribution networks but also into buildings. For example, in solar power systems, batteries can store surplus production that cannot be used immediately on-site.

Norelco – building future reliability

Norelco Oy is a Finnish family-owned company that has been developing safe and intelligent power distribution solutions for over 60 years. We manufacture flexible and reliable power distribution systems tailored for energy storage and battery systems. The most convenient solution is a factory-built turnkey package, where all electrical components are installed and tested, ready for deployment. Our strengths lie in combining modular design, domestic manufacturing, and customer-oriented service.

Norelco’s NorUnit power distribution unit enables fast and safe connection between battery storage and the power grid. The same unit can also house the customer’s IT systems. For systems under 1.6 MW, Norelco’s outdoor substations are ideal, offering scalability and maintenance-free operation. Low-voltage switchgear is implemented using the NorPower 5000 LV switchgear, ensuring high reliability and safety even at high current levels.
