Application to amend condition 1 of planning permission reference C21/0934/15/AC for the installation of underground 132kV grid connection cables between the Glyn Rhonwy Pumped Storage Facility and Pentir Substation to extend the development commencement period for an additional 2 years.

Attention was drawn to the late observations form which included an update to the relevant planning history.

The Development Control Team Leader highlighted that an application to amend the condition relating to the commencement period of the development was granted in January 2022 under reference C21/0934/15/AC so as to provide an additional two years, i.e. until 10/1/2024.

It was explained that the principle of the development of installing an underground cable to connect the Glyn Rhonwy pumped storage generating station with the Pentir substation had already been established by the Local Planning Authority by means of planning permission C16/0886/15/LL and the application before them involved extending the development's operating period by an additional 2 years by amending condition 1 of application C21/0934/15/AC.  It was confirmed that there were no changes to the plan and that the process of releasing conditions associated with the original planning permission continued. However, the importance of considering whether local and national planning policy circumstances or the policy position had changed since the application was originally granted was highlighted.  Only if there was evidence of a significant change in position could the proposal be considered differently in the context of local relevant policies relating to the acceptability of the principle of this latest application - Policy ISA 1 'Infrastructure Provision' and policy PS 7 'Renewable Technology'. Policy ISA 1 of the Local Development Plan (LDP) states

It was reported that the proposed cable path runs through the 'North-Western Fringes of Snowdonia' Special Landscape Area, the 'Dinorwig' Landscape of Outstanding Historic Interest and borders the 'North-West Wales Slate Landscape' World Heritage Site; the intention was to lay an underground cable in line with the guidance in policy PS 7.

It was reiterated that the principle of creating a pumped storage generating station at Glyn Rhonwy quarry had already been accepted and approved by the Secretary of State for Business, Energy and Industrial Strategy granting a Development Consent Order in 2017. Permission for a non-material amendment to the Development Consent Order was granted by Welsh Ministers to extend the operational period. The work of creating a grid connection could usually be considered as an Associated Development but here in Wales it could not be approved as part of the process; therefore, a separate formal application for permission must be submitted in line with the Planning Act.  The principle was deemed acceptable and that this element was a necessary follow-up step to the planning permission already granted by ensuring a link between the electricity generating site and the distribution site.

In the context of visual, general and residential amenities it was accepted that this type of work, particularly given that it would be undertaken on the verges of busy public roads, would be likely to affect local  ...  view the full minutes text for item 6
