DERIVATION OF PRE-ADJUSTMENT
ENTRY TARIFFS
The general formula for entry tariffs at a given Point P can be expressed as follows.
is the value of TSO revenues to be collected from capacity at entry points
(500€ here, as per assumptions).
For example, the tariff for entry point A is defined according to previous tables.
The pre-adjustment CWD counterfactual tariff at entry from storage point A is
1.0319€/(kWh/d)/y
. Similar calculations are used to derive CWD tariffs at other
entry points.
DERIVATION OF PRE-ADJUSTMENT
EXIT TARIFFS
The general formula for exit tariffs at a given Point P can be expressed as follows.
is the value of TSO revenues to be collected from capacity at exit points (€500
here, as per assumptions).
For example, the tariff for exit point A is defined according to previous tables.
The pre-adjustment CWD counterfactual tariff at entry from storage point A is
0.8564€/(kWh/d)/y
. Similar calculations are used to derive CWD tariffs at other exit
points.
