Understanding S.I. No. 445 of 2000

S.I. No. 445 of 2000, formally known as the "European Communities (Internal Market in Electricity) Regulations, 2000," is a key statutory instrument in Ireland. These Regulations give legal effect to Directive No. 96/92/EC of the European Parliament and of the Council of 19th December 1996. This directive concerns common rules for the internal market in electricity. The Regulations establish the framework for Ireland's electricity market, focusing on the roles of the Transmission System Operator (TSO) and Distribution System Operator (DSO), and their unbundling from commercial generation and supply activities.

EirGrid's Establishment and Role as TSO

A central provision of S.I. No. 445 of 2000 is the establishment of EirGrid. The company referred to in Regulation 34 shall be known as EirGrid. EirGrid is designated as the independent Transmission System Operator (TSO). A licence under section 14(1)(e) of the Act of 1999 is granted only to EirGrid for this role.

EirGrid is mandated to prepare a code of conduct for approval by the Commission. This code applies to every director of EirGrid and to every person employed by the company. This code of conduct must be included as part of every contract of employment with EirGrid.

Unbundling and Licensing Requirements

The Regulations detail specific licensing requirements under the Electricity Regulation Act 1999, as inserted by Regulation 32 of S.I. No. 445 of 2000.

• Transmission System Operator (TSO) Licence: A licence under section 14(1)(e) of the Act of 1999 shall only be granted to EirGrid.
• Distribution System Operator (DSO) Licence: Only the Board (ESB) may be issued with a licence under section 14(1)(g) of the Act of 1999.
• Transmission System Owner Licence: Only the Board (ESB) may be issued with a licence under section 14(1)(f) of the Act of 1999.

This framework aims to ensure functional separation between network operation and commercial activities. We have not verified the specific details of how the Commission for Regulation of Utilities (CRU, formerly CER) licenses and regulates EirGrid and ESB Networks. However, the intent is to prevent anti-competitive cross-subsidisation.

Capital Expenditure and Financial Oversight

S.I. No. 445 of 2000 also places controls on EirGrid's financial operations, particularly regarding capital expenditure. EirGrid shall not incur any expenditure for capital purposes without the approval of the Minister. Furthermore, the total expenditure of EirGrid for capital purposes shall not exceed such sum as may stand specified from time to time by the Minister. The aggregate at any time of borrowings by EirGrid under subparagraph (a) shall not exceed specified limits.
