Representation

Relevant Representation of National Grid Electricity Transmission Plc in respect of the Mona Offshore Wind Farm Development Consent Order (the “Order”) This relevant representation is submitted on behalf of National Grid Electricity Transmission Plc (“NGET”) in respect of Mona Offshore Wind Limited’s (the “Applicant”) application for the Order which seeks powers to enable the construction of an offshore wind farm with an approximate capacity of 1500MW in the Irish Sea (“Project”), and in particular NGET’s infrastructure and land which is within or in close proximity to the proposed limits of the Order (“Order Limits”). NGET will require appropriate protection for retained and future apparatus including compliance with relevant standards for works proposed within close proximity of its apparatus. NGET’s rights of access to inspect, maintain, renew and repair such apparatus must also be maintained at all times and access to inspect and maintain such apparatus must not be restricted. Further, where the Applicant intends to acquire land or rights, or interfere with any of NGET’s existing or future interests in land or apparatus, NGET will require appropriate protection and further discussion is required on the impact to its apparatus and rights. Existing NGET infrastructure within/in close proximity to the proposed Order Limits: NGET owns or operates the following infrastructure within or in close proximity to the proposed Order Limits for the Project. These assets form an essential part of the electricity transmission network in England and Wales. The details of the electricity assets are as follows: Substation: • Bodelwyddan 400kV Substation Associated overhead and underground apparatus including cables Overhead Lines: • 4ZB 400kV OHL Bodelwyddan - Deeside - Pentir 1 Bodelwyddan - Deeside - Pentir 2 • GM Route 400kV OHL Bodelwyddan - Deeside - Pentir 2 Associated cable fibre Cable Apparatus: • Pentre-Mawr Cable Compound • Deeside - Pentir 1 Cable • Bodelwyddan 4 St Asaph 132kv Cable Sections 01 And 02 Future NGET infrastructure within/in close proximity to the proposed Order Limits: The proposed Order Limits overlap with land required for the following future NGET infrastructure which are required for future generation connections (subject to obtaining the necessary consents and land rights): · The extension of the existing Bodelwyddan 400 kV substation (Substation Extension); and · Reconfiguration of the existing overhead line section 4ZB166-168 (OHL Works). The Substation Extension works and the footprint of the Substation Extension sit wholly within the red-line boundary of the Project which also overlaps with land required for the OHL Works. The draft Order includes powers for the Applicant to undertake electrical works to connect to the new Substation Extension (Work No. 26) and acquire new rights within plot 11-203 (being the location of the Substation Extension). The draft Order seeks powers for the Applicant within plots 11-197, 11,198, 11-199, 11-200, 11,206, 11-207, 11-208, 11-209, 11-210 and 11-211 to place permanent landscaping, ecological and environmental works, including watercourse realignment and attenuation pond(s); temporary construction compound and laydown area; and access during construction. NGET has engaged with the Applicant at the DCO pre-application stage and has submitted consultation responses to make it clear to the Applicant that the Applicant must have regard to the Substation Extension, OHL Works and enabling works in developing its scheme. NGET will require a form of protective provisions which includes protection in respect of Substation Extension and OHL Works and ensures that the Applicant is not permitted to carry out connection works within the Substation Extension area, OHL Works area or operational land without the agreement of NGET. In order to avoid serious detriment to NGET and its undertaking, the Applicant must not be granted powers of compulsory acquisition in respect of any land required for the Substation Extension or OHL Works. Protection of NGET Assets: As a responsible statutory undertaker, NGET’s primary concern is to meet its statutory obligations and ensure that any development does not impact in any adverse way upon those statutory obligations. As such, NGET has a duty to protect its position in relation to infrastructure and land which is within or in close proximity to the draft Order Limits. As noted, NGET’s rights to retain its apparatus in situ and rights of access to inspect, maintain, renew, repair and refurbishment such apparatus located within or in close proximity to the Order Limits should be maintained at all times and access to inspect and maintain such apparatus must not be restricted. NGET will require protective provisions to be included within the Order for the Project to ensure that its interests are adequately protected and to ensure compliance with relevant safety standards. NGET is liaising with the Applicant in relation to such protective provisions, along with any supplementary agreements which may be required. NGET requests that the Applicant continues to engage with it to provide explanation and reassurances as to how the Applicant’s works pursuant to the Order (if made) will ensure protection for those NGET assets which will remain in situ, along with facilitating all future access and other rights as are necessary to allow NGET to properly discharge its statutory obligations. NGET will continue to liaise with the Applicant in this regard with a view to concluding matters as soon as possible during the DCO Examination and will keep the Examining Authority updated in relation to these discussions. Compulsory Acquisition Powers in respect of the Project: The Applicant is seeking compulsory powers over a number of plots which include both existing and future NGET overhead line assets and/or interests. As noted, where the Applicant intends to acquire land or rights, or interfere with any of NGET’s interests in land, NGET will require further discussion with the Applicant and NGET will require its standard Protective Provisions to be included within the Order NGET reserves the right to make further representations as part of the Examination process in relation to specific interactions with its assets but in the meantime will continue to liaise with the Applicant with a view to reaching a satisfactory agreement.
