CHAPTER VI U.K. UNBUNDLING OF TRANSMISSION SYSTEM OPERATORS

Section 1 U.K. Ownership unbundling

Article 43 U.K. Ownership unbundling of transmission systems and transmission system operators

1. Member States shall ensure that:

(a) each undertaking which owns a transmission system acts as a transmission system operator;

(b) the same person or persons are not entitled either:

(i)

directly or indirectly to exercise control over an undertaking performing any of the functions of generation or supply, and directly or indirectly to exercise control or exercise any right over a transmission system operator or over a transmission system; or

(ii)

directly or indirectly to exercise control over a transmission system operator or over a transmission system, and directly or indirectly to exercise control or exercise any right over an undertaking performing any of the functions of generation or supply;

(c) the same person or persons are not entitled to appoint members of the supervisory board, the administrative board or bodies legally representing the undertaking, of a transmission system operator or a transmission system, and directly or indirectly to exercise control or exercise any right over an undertaking performing any of the functions of generation or supply; and

(d) the same person is not entitled to be a member of the supervisory board, the administrative board or bodies legally representing the undertaking, of both an undertaking performing any of the functions of generation or supply and a transmission system operator or a transmission system.

2. The rights referred to in points (b) and (c) of paragraph 1 shall include, in particular:

(a) the power to exercise voting rights;

(b) the power to appoint members of the supervisory board, the administrative board or bodies legally representing the undertaking; or

(c) the holding of a majority share.

3. For the purpose of point (b) of paragraph 1, the notion ‘undertaking performing any of the functions of generation or supply’ shall include ‘undertaking performing any of the functions of production and supply’ within the meaning of Directive 2009/73/EC, and the terms ‘transmission system operator’ and ‘transmission system’ shall include ‘transmission system operator’ and ‘transmission system’ within the meaning of that Directive.

4. The obligation set out in point (a) of paragraph 1 shall be deemed to be fulfilled in a situation where two or more undertakings which own transmission systems have created a joint venture which acts as a transmission system operator in two or more Member States for the transmission systems concerned. No other undertaking may be part of the joint venture, unless it has been approved under Article 44 as an independent system operator or as an independent transmission operator for the purposes of Section 3.

5. For the implementation of this Article, where the person referred to in points (b), (c) and (d) of paragraph 1 is the Member State or another public body, two separate public bodies exercising control over a transmission system operator or over a transmission system on the one hand, and over an undertaking performing any of the functions of generation or supply on the other, shall be deemed not to be the same person or persons.

6. Member States shall ensure that neither commercially sensitive information referred to in Article 41 held by a transmission system operator which was part of a vertically integrated undertaking, nor the staff of such a transmission system operator, is transferred to undertakings performing any of the functions of generation and supply.

7. Where on 3 September 2009, the transmission system belongs to a vertically integrated undertaking a Member State may decide not to apply paragraph 1.

In such case, the Member State concerned shall either:

(a) designate an independent system operator in accordance with Article 44; or

(b) comply with Section 3.

8. Where, on 3 September 2009, the transmission system belongs to a vertically integrated undertaking and there are arrangements in place which guarantee more effective independence of the transmission system operator than Section 3, a Member State may decide not to apply paragraph 1.

9. Before an undertaking is approved and designated as a transmission system operator under paragraph 8 of this Article, it shall be certified in accordance with the procedures laid down in Article 52(4), (5), and (6) of this Directive and in Article 51 of Regulation (EU) 2019/943, pursuant to which the Commission shall verify that the arrangements in place clearly guarantee more effective independence of the transmission system operator than Section 3 of this Chapter.

10. Vertically integrated undertakings which own a transmission system shall not in any event be prevented from taking steps to comply with paragraph 1.

11. Undertakings performing any of the functions of generation or supply shall not in any event be able to directly or indirectly take control over or exercise any right over unbundled transmission system operators in Member States which apply paragraph 1.

Section 2 U.K. Independent system operator

Article 44 U.K. Independent system operator

1. Where the transmission system belongs to a vertically integrated undertaking on 3 September 2009, Member States may decide not to apply Article 43(1) and designate an independent system operator upon a proposal from the transmission system owner. Such designation shall be subject to approval by the Commission.

2. The Member State may approve and designate an independent system operator provided that:

(a) the candidate operator has demonstrated that it complies with the requirements laid down in points (b), (c) and (d) of Article 43(1);

(b) the candidate operator has demonstrated that it has at its disposal the required financial, technical, physical and human resources to carry out its tasks under Article 40;

(c) the candidate operator has undertaken to comply with a ten-year network development plan monitored by the regulatory authority;

(d) the transmission system owner has demonstrated its ability to comply with its obligations under paragraph 5. To that end, it shall provide all the draft contractual arrangements with the candidate operator and any other relevant entity; and

2. By way of derogation from paragraph 1, Member States may allow transmission system operators to own, develop, manage or operate energy storage facilities, where they are fully integrated network components and the regulatory authority has granted its approval, or where all of the following conditions are fulfilled:

(a) other parties, following an open, transparent and non-discriminatory tendering procedure that is subject to review and approval by the regulatory authority, have not been awarded a right to own, develop, manage or operate such facilities, or could not deliver those services at a reasonable cost and in a timely manner;

(b) such facilities or non-frequency ancillary services are necessary for the transmission system operators to fulfil their obligations under this Directive for the efficient, reliable and secure operation of the transmission system and they are not used to buy or sell electricity in the electricity markets; and

(c) the regulatory authority has assessed the necessity of such a derogation, has carried out an ex ante review of the applicability of a tendering procedure, including the conditions of the tendering procedure, and has granted its approval.

The regulatory authority may draw up guidelines or procurement clauses to help transmission system operators ensure a fair tendering procedure.

3. The decision to grant a derogation shall be notified to the Commission and ACER together with relevant information about the request and the reasons for granting the derogation.

4. The regulatory authorities shall perform, at regular intervals or at least every five years, a public consultation on the existing energy storage facilities in order to assess the potential availability and interest of other parties in investing in such facilities. Where the public consultation, as assessed by the regulatory authority, indicates that other parties are able to own, develop, operate or manage such facilities in a cost-effective manner, the regulatory authority shall ensure that transmission system operators' activities in this regard are phased-out within 18 months. As part of the conditions of that procedure, regulatory authorities may allow the transmission system operators to receive reasonable compensation, in particular to recover the residual value of their investment in the energy storage facilities.

5. Paragraph 4 shall not apply to fully integrated network components or for the usual depreciation period of new battery storage facilities with a final investment decision until 2024, provided that such battery storage facilities are:

(a) connected to the grid at the latest two years thereafter;

(b) integrated into the transmission system;

(c) used only for the reactive instantaneous restoration of network security in the case of network contingencies where such restoration measure starts immediately and ends when regular re-dispatch can solve the issue; and

(d) not used to buy or sell electricity in the electricity markets, including balancing.

Section 5 U.K. Unbundling and transparency of accounts

Article 55 U.K. Right of access to accounts

1. Member States or any competent authority that they designate, including the regulatory authorities referred to in Article 57, shall, insofar as necessary to carry out their functions, have right of access to the accounts of electricity undertakings as set out in Article 56.

2. Member States and any designated competent authority, including the regulatory authorities, shall preserve the confidentiality of commercially sensitive information. Member States may provide for the disclosure of such information where such disclosure is necessary in order for the competent authorities to carry out their functions.

Article 56 U.K. Unbundling of accounts

1. Member States shall take the necessary steps to ensure that the accounts of electricity undertakings are kept in accordance with paragraphs 2 and 3.

2. Electricity undertakings, whatever their system of ownership or legal form, shall draw up, submit to audit and publish their annual accounts in accordance with the rules of national law concerning the annual accounts of limited liability companies adopted pursuant to Directive 2013/34/EU.

Undertakings which are not legally obliged to publish their annual accounts shall keep a copy of these at the disposal of the public in their head office.

3. Electricity undertakings shall, in their internal accounting, keep separate accounts for each of their transmission and distribution activities as they would be required to do if the activities in question were carried out by separate undertakings, with a view to avoiding discrimination, cross-subsidisation and distortion of competition. They shall also keep accounts, which may be consolidated, for other electricity activities not relating to transmission or distribution. Revenue from ownership of the transmission or distribution system shall be specified in the accounts. Where appropriate, they shall keep consolidated accounts for other, non-electricity activities. The internal accounts shall include a balance sheet and a profit and loss account for each activity.

4. The audit referred to in paragraph 2 shall, in particular, verify that the obligation to avoid discrimination and cross-subsidisation referred to in paragraph 3 is respected.
