TSOs or, if applicable, transmission capacity allocators shall be considered as the primary owners of the information they calculate and provide.
2. The information laid down in paragraph 1(a) shall be published as set out in the Annex.
3. In relation to direct current links, TSOs shall provide updated information on any restrictions placed on the use of available cross-border capacity including through the application of ramping restrictions or intraday transfer limits not later than one hour after the information is known to the ENTSO for Electricity.
Operators of direct current links shall be considered as primary owners of the updated information they provide.
4. TSOs or, if applicable, transmission capacity allocators, shall provide a yearly report to the national regulatory authority indicating:
(a) the main critical network elements limiting the offered capacity;
(b) the control area(s) which the critical network elements belong to;
(c) the extent to which relieving the critical network elements would increase the offered capacity;
(d) all possible measures that could be implemented to increase the offered capacity, together with their estimated costs.
When preparing the report TSOs may choose not to identify the asset concerned and specify its location if it is classified as sensitive critical infrastructure protection related information in the United Kingdom as provided for in point (d) of Article 2 of Directive 2008/114/EC.
TSOs or, if applicable, transmission capacity allocators shall be considered as primary owners of the report they provide.
