BESS battery energy storage

Q: Why is a battery storage system a strategic investment?

The energy transition creates new opportunities. As electricity generation shifts toward renewable energy sources, the power grid becomes more unstable. This creates growing demand for balancing services—exactly what your battery storage system provides. Prices are rising continuously. Electricity transmission fees and grid charges are increasing. A battery storage system acts as insurance against these rising costs and, in addition to savings, enables new revenue streams. Regulation is steering investments. EU energy efficiency requirements and carbon footprint reporting are forcing properties to invest in smart energy solutions.

Q: What are the benefits of battery storage?

Here are the key benefits: Investment profitability Using systems as a revenue-generating resource improves the profitability of investments. In existing properties, the electricity connection is transformed from a cost into a source of income. Even an undeveloped plot of land can be made profitable. Supporting the sustainable energy transition The systems support the integration of renewable energy sources into the power grid by balancing fluctuations in supply and demand. Supporting the electricity grid Participation in Fingrid’s reserve markets helps ensure frequency control of the power grid and prevents disturbances. Flexibility of the energy system The systems can operate simultaneously in multiple roles, such as reserve capacity and load balancing. This provides customers with versatile energy management solutions. Security of supply The systems help ensure continuity of operations even during potential grid faults, maintenance, or disturbance situations. Technological leadership An operator can position itself as a modern and innovative energy player that leverages new technologies and opportunities in energy markets.

Store excess energy and release it for use later.

Reduce the cost of purchased electricity and earn revenue from reserve markets.

Increase grid stability and improve security of supply in exceptional situations.

A BESS battery storage system is a smart and profitability-enhancing investment opportunity.

A BESS (Battery Energy Storage System) is an energy solution based on battery technology that stores electricity and releases it for use when market production decreases or electricity prices are higher.

A functioning electricity market requires flexible energy solutions to maintain balance—battery storage is a precise solution to this need. A BESS battery storage system can respond quickly and efficiently to prevailing conditions, which also ensures optimised cash flow for the investment owner through multiple reserve markets.

We serve customer segments that benefit from BESS investments in a versatile way: we create added value for the energy sector, industry, and traditional real estate business alike. Sitowise’s comprehensive design expertise guarantees a turnkey solution also for companies with limited resources for project management.

When an electricity connection is transformed from a mandatory expense into a revenue-generating resource, even an undeveloped plot of land becomes financially viable.

A BESS battery energy storage system saves, generates, and safeguards.

Energy is stored in the batteries during periods of overproduction or low prices and released for use when production decreases or consumption increases. A battery storage system cuts peak demand, increases energy self-sufficiency, and enables revenue generation from reserve markets. Problems caused by power outages are also reduced when the energy stored in the batteries is put to use.

Battery energy storage system and its role in integrating renewable energy

BESS play a key role in integrating renewable energy sources: they store surplus wind and solar energy and feed it back into the grid during peak demand or when production is low. Battery storage enables a higher share of clean energy and reduces dependence on fossil fuels.

Reserve markets generate additional revenue and improve the profitability of a BESS investment.

Using batteries as a revenue-generating resource significantly improves the profitability of the investment. Participation in transmission grid balancing services provides additional income and shortens the payback period of the investment. Typically, 90% of the revenue goes to the customer and 10% to the system provider—making the investment particularly attractive and profitable.

Frequently asked questions about BESS battery storage

What is a BESS battery energy storage system?

A BESS battery energy storage system, or battery energy storage, is a battery-based system used to store electrical energy and release it later for applications such as buildings, electrical substations, transmission networks, and renewable energy production. The abbreviation BESS comes from the term Battery Energy Storage System.

What does a battery energy storage system help with?

Energy storage makes it possible to take advantage of electricity price flexibility, reducing energy costs by shifting consumption to lower-priced hours. Participation in reserve markets also improves the reliability and stability of the electricity grid.
