Cohrs Fruit Farm – Energy efficiency in fruit growing

The Cohrs fruit farm in Jork relies on a modern energy concept to meet its high cooling requirements in an economical and sustainable manner. With a PV system, battery storage, and dynamic electricity rates, you get a system that reacts flexibly, reduces costs, and ensures the quality of stored goods.

Benefits for Obsthof Cohrs

Higher self-consumption
Stored solar power is used optimally in farm operations
Intelligently reducing energy costs
Using cheaper tariff periods reduces the energy costs of cooling
Reliable protection for cooling systems
Constant energy supply ensures the quality of stored goods
Sustainable and efficient farm management
Optimized energy flows reduce CO₂ emissions and strengthen the farm's energy self-sufficiency.

Implemented use case

The farm wanted to better control the highly fluctuating energy costs and operate the large cold storage facilities more efficiently. The aim was to make optimum use of low electricity price phases, integrate more PV electricity, and strengthen the security of supply for the cooling systems.

Self-consumption optimization
Independent and sustainable
Dynamic electricity prices
Always save optimally

Aim of the project

The farm wanted to better control the highly fluctuating energy costs and operate the large cold storage facilities more efficiently. The aim was to make optimum use of low electricity price phases, integrate more PV electricity, and strengthen the security of supply for the cooling systems.

Our customized solution

A 133 kWh battery storage system with 100 kW capacity was installed, which intelligently controls electricity consumption. The system stores PV or grid power depending on the tariff price and weather conditions and supplies the cooling systems with the cheapest available energy at all times. This makes the fruit farm more self-sufficient, economical, and secure in terms of supply.
