Sales calculations

For the Feed-in-Tarrif, Market Price and PPA Pay-as-Produced, the following formula defines the payout, where Driver stands as example for "Net Production" or "Power", and the Value is the market price or fixed tariff that is paid. 

For Annual Baseload and Monthly Baseload PPAs, the calculation logic is differently. In those cases, the electricity provider (here the project) is contractually obliged to deliver a certain amount of electricity, either on a yearly (annual baseload) or monthly 
(monthly baseload) basis. The revenues for the contracted delivery profile are calculated as above, by multiplying the Driver x Value. However, there are additional revenues in case production is above the delivery profile, and additional costs in case the production is below the contracted delivery profile. To calculate the additional revenues/costs, a selling and buying price has to be added. In case of a higher production than the delivery profile, the additional production is multiplied by the selling price, and the result is the additional income of that period. In case of a lower production than contractually defined , the missing production is multiplied by the buying price, resulting in the additional costs.

The end value of a tariff-price group can be defined as a fix value dependent on an event (for example Last Production Unit End (Mode = Fix) or after achieving a certain production amount in MWh (Mode = Quotal).
