Optimise your purchases with VTA-DESY!
VTA-DESY, our decarbonisation system, allows you to incorporate the increasingly strict statutory decarbonisation regulations (GHG quota) as well as the quality standards and properties of fuels in your purchase calculations for (bio)fuels. This way, you can optimise your purchases and at the same time ensure that you are complying with all the requirements.
Framework conditions
When using VTA-DESY, the greenhouse gas reductions are examined cumulatively for the entire year. In order to meet the overriding GHG objective, the optimisation takes place across product boundaries. All existing and future fulfilment options can be flexibly integrated into the calculation model (tickets, use of electronic motor vehicles, UER).
The model divides the year into three phases:
Past
The fuels have been put on the market and the GHG reduction in kg/CO2eq is set. For the optimisation, these results are entered as a quota excess or underfulfilment in kg/CO2eq.
Current month of planning
The available total quantities and the quantities in each tank are known and the product batches are calculated on a monthly basis.
Remaining year
For the rest of the year, pool quantities are observed. Here, purchases of alternative components with different properties (e.g. CO2 emissions) can be examined. It is important to note that all three phases are always considered in one optimisation run.
Important questions that must be answered:
Long-term planning/yearly planning
Options for spontaneous procurement
Short-term planning
