On the 8th of March 2017, the Glyn Rhonwy project was awarded a Development Consent Order (DCO) from the Secretary of State for Business, Energy & Industrial Strategy. It is the first of it's kind to be consented under the Planning Act 2008 as a Nationally Significant Infrastructure Project (NSIP). 

The full suite of planning and examination materials as well as the DCO can be found on the Planning Inspectorate website for the development.

Grid Connection

The 132KV underground cable grid connection, running from the Glyn Rhonwy industrial estate to Pentir substation, was granted planning permission by Gwynedd Council on the 26th of September 2016.

More information on the grid connection, including route and planning decision can be found on the Gwynedd Council website for the planning application.

Environmental permitting

The Glyn Rhonwy project has been granted an abstraction license to allow abstraction of water from Llyn Padarn to fill the scheme to operating volume. This is a low rate of abstraction, taken gradually over the course of the construction of the scheme.

Environmental Permits required to discharge standing water from the site prior to construction, and then to discharge excess water during operation of the scheme, have also been granted by Natural Resources Wales.

Ongoing work

We are currently working on fulfilling the various planning requirements specified within the Development Consent Order, as well as detailed engineering design.
