Any contracted capacity at the interconnection points, regardless of the date of its conclusion, shall be transferred to the virtual interconnection point.
A virtual interconnection point shall be established provided that the following conditions are met:
|
(a)
|
the total technical capacity at the virtual interconnection points is equal to or higher than the sum of the technical capacities at each of the interconnection points contributing to the virtual interconnection points;
|
|
(b)
|
the virtual interconnection point facilitates the economic and efficient use of the system including the rules laid down in Articles 10 and 11.
