With cooling, the price of electricity is not the only factor.

Cooling, freezing, ventilation, pumps and compressors may run continuously. The energy also protects the value of stored products and the continuity of production.

BESS – Battery Energy Storage System can be part of a solution for consumption, power and backup. First, however, we need to understand the cooling equipment and its operating limits.

We address peaks together with their cause.

When compressors and other equipment run at the same time, an increased power demand can arise. Part of it can be addressed by controlling the equipment, part of it, depending on the design, by a battery.

We do not look only at the size of the peak. We are interested in its duration, recurrence and its relationship to temperature, operation and the way the equipment is controlled.

Energy can also be stored in the form of cold.

Some cooling systems have thermal inertia and some room to shift consumption in time. Under suitable conditions, part of the energy can be used for pre-cooling instead of being stored in an electrical battery.

Such control must respect the product, the required temperatures and the technical possibilities. Energy optimisation must not compromise the quality or safety of the operation.

We use photovoltaics directly first.

Daytime cooling consumption can overlap with PV generation. If surpluses arise, we assess their direct use, thermal flexibility and storage in BESS.

We work with a longer period. A summer day may not reflect year-round consumption or the economics of the battery.

We back up critical cooling circuits.

During an outage, it may not be necessary to keep the whole site at full power. We identify the critical compressors, pumps, controls and storage rooms, the required backup time and the capabilities of existing sources.

Battery backup must be technically designed. For longer outages, a combination with another backup source may be suitable. A reserve kept for outages also reduces the capacity available for everyday optimisation.

Let's start with consumption and operating limits.

We need energy data, a description of the cooling, temperature requirements, own generation and information about the consequences of an outage. We compare the energy benefits, the cost of the solution and the value of reducing operational risk.
