BESS Solutions for Business: Energy Storage When You Need More Flexibility
BESS (Battery Energy Storage System) is an advanced system that stores electrical energy and allows it to be used strategically at the most advantageous times.
In manufacturing, logistics, retail, or other facilities, energy consumption is rarely completely consistent. At times, less electricity is needed, while at others, the load spikes. And it is precisely in these cases that the BESS storage system helps manage energy more flexibly in daily business operations and reduces costs.
What does a BESS system consist of?
From the outside, a BESS may look like a simple technical container, but the most important work happens inside the system: battery modules store energy, inverters convert it for on-site use or feed it into the grid, and control equipment determines when to charge and when to release it. Meters, transformers, cooling, and safety solutions also work together. Therefore, a BESS should be viewed as a complex engineering solution.
When should a business consider a BESS?
If daily or weekly electricity consumption fluctuates significantly, it’s worth considering a BESS solution. Irregularities in energy consumption can occur in manufacturing when equipment is started up, in a logistics facility during peak loading, at a gate, or during refrigeration system operations, or in a retail building when refrigeration equipment, air conditioning, lighting, or electric vehicle charging stations are all running simultaneously.
A BESS storage system can reduce electricity draw from the grid. Some of the energy will be drawn from the storage unit, and the load will be distributed more evenly. This is particularly relevant when a company begins to run short on available power or when short power spikes occur repeatedly every workday.
How does BESS help shift some consumption to more favourable times?
The price of electricity fluctuates throughout the day, but with a storage system, some of these fluctuations can be leveraged. The system is charged during off-peak hours, and the stored energy is used when electricity is more expensive or when the facility needs more of it. This effectively shifts part of the consumption to a more favourable time, making electricity a more manageable resource.
If a company knows when its demand typically increases, it can prepare its storage system in advance. This reduces electricity draw from the grid during peak hours, and part of the demand is covered by previously stored energy. When the system is managed based on actual consumption, electricity bills could be reduced by up to 30%.
Can a BESS operate without a solar power plant?
A BESS does not necessarily have to be connected to a solar power plant. The system can be charged from the grid when it is cost-effective, and the stored energy can be used later—during peak hours, at times of high demand, or when the facility needs more power.
When paired with a solar power plant, the storage system helps utilise more locally generated energy. Without a solar power plant, it can function as a standalone solution for managing energy consumption and loads.
Energy Trading and Balancing Services
The value of a BESS can extend beyond the facility’s own energy consumption. A properly selected and managed storage system can be utilised more actively—by participating in the electricity market or providing balancing services through independent suppliers or other market partners prepared to do so.
One possible model is exploiting differences in electricity prices. The storage system is charged when electricity is cheaper on the market, and the stored energy is used or fed into the grid when demand and prices are higher. In this way, BESS helps not only to manage electricity costs but also, under the right conditions, to create additional economic value.
In more complex models, several storage systems, solar power plants, or other flexible electricity consumers are connected into a common control network. The system can then respond to the power grid's needs and fluctuations in load, helping maintain its stability.
Such a scenario requires appropriate equipment, clear management, contracts, and reliable market partners. Therefore, in this case, BESS becomes not only an equipment that helps reduce electricity costs but also a value-adding solution capable of opening new revenue opportunities.
Why is smart management important?
A storage system alone does not guarantee benefits, and the same system can operate very differently across facilities. In some cases, it’s worth charging it at night; in others, keeping it ready for a sudden power surge; and in still others, coordinating it with solar power generation or market signals.
This requires smart BESS management. It can be ensured by an energy management system (EMS) or another tailored management solution that evaluates consumption patterns, electricity prices, power demand, the battery’s charge level, technical limits, and the facility’s operating mode.
When this data is evaluated together, the storage system operates not according to a generic scheme, but based on the specific needs of the facility. The system can determine when to store energy, when to use it, and when to leave a reserve for future needs.
Where to start when planning a BESS?
When working on BESS projects, PINUS LT first determines what the company wants to manage: load peaks, price fluctuations, available power limits, surplus solar power, future expansion, or participation in the energy market. Only then do we move on to technical solutions: we select a storage system capacity and power that match the facility’s actual needs, plan management, installation, and safety solutions, and evaluate the payback period.
