The problem

Snowdonia Pumped Hydro Ltd (SPH) have obtained planning permission from Gwynedd Council for a 49.9MW pumped storage development at Glyn Rhonwy, and are now applying to double the capacity of the project to 99.9MW.

Threat of new pylons?

We are concerned that the development could result in new pylons blighting the iconic views of northern Snowdonia, and that there are currently no safeguards against this happening. We are also concerned about the potential impacts on access and local water bodies including Llyn Padarn.

The detail

This application is currently being dealt with as a ‘major infrastructure project’ by the Planning Inspectorate on behalf of the Department of Energy and Climate Change.

As part of the application process SPH are required to consult on their plans. The Snowdonia Society has made several submissions to the developer’s consultation.
