Many wineries do not have precise information about their energy consumption or the energy sources they use
For energy sources, only annual consumption figures are known
No information is available on the energy mix used
Energy-saving opportunities are not identified, or are identified too late
Use of outdated technology (cooling, lighting, heating)
Declines in the efficiency of individual machines and energy distribution systems (electricity, cooling/heating) go unnoticed
No precise knowledge of the performance of the company’s own PV system (production, self-consumption, feed-in, time-of-day peaks)
Outdated machinery is often replaced too late because the performance and efficiency of energy-consuming components are not measured.
Initial research findings show that German wineries use different energy mixes for wine production, resulting in significant variations in the amount of energy required per liter of wine.
The main energy sources in viticulture are:
Structure of the research project:
Development and integration of an energy management system (EnMS) in small and medium-sized wineries to measure the energy flows of all energy sources used in wine production by
Installation of sensors that accurately record the energy use of different consumers and the various energy sources, broken down by room, work step or individual appliance. The sensors can record all the different energy sources.
The energy data, which is collected automatically and closely (every 5 minutes) by telemetry, is processed and evaluated using software. Individual load profiles are visualized and can be called up using a computer, tablet or smartphone via the Vinergy app.
The energy data collected from various wineries is stored and analyzed on a central server by the DLR-RP in Neustadt an der Weinstraße. This allows a cross-regional comparison of different types of operation and is used for individual energy consulting by the DLR-RLP.
In this way, winegrowing businesses receive precise values on their internal energy use and can take various steps on the basis of this data, such as
Anonymous comparison with similar types of operation
Energy efficiency assessment
Analysis of the efficiency and function of individual appliances
Checking the applicability and cost-effectiveness of optimization approaches developed as part of the CIP.
Fuel consumption of vineyard tractors
In contrast to the rest of the agricultural sector, there is no measurement option ex works.
Data is collected directly in the tractor using a computer system and processed automatically.
The following parameters are recorded:
Fuel consumption/hour/minute/ha,
area output ha/h, co2/ha
Distance traveled and time
Work steps and attachments such as leaf cutters or cultivators
Road travel, work, turning, preparation, turning time and distance
It is possible to calculate the costs of the individual tasks in the vineyard
Aims of the research project:
Development of a user-friendly energy management system based on automated energy monitoring.
An EnMS can be used as a basis for certifying your own company in ecological and sustainability issues
Planning the use of resources and making them more efficient
Cost savings
Individual advice for wineries from DLR on energy efficiency and energy savings based on the data collected
Introduction of fixed measurement units
kWh/liter of wine and kWh/ha of vineyard
Raising awareness of energy use/efficiency among employees and customers
Advantages of an integrated energy management system (EnMS)
