2. The Proposed Application will seek development consent for the demolition of an existing Gas Treatment Plant (‘GTP’), distinct from the existing Connah’s Quay Power Station, and Above Ground Installation (‘AGI’), store buildings, and contractors’ facilities on site and the construction, operation and maintenance of a new Combined Cycle Gas Turbine (‘CCGT’) electricity generating station of around 1,100 megawatts (‘MW’) and up to 1,380 MW net electrical output with Carbon Capture Plant ('CCP'); water abstraction and discharge and electricity connections; a carbon dioxide connection to the HyNet Carbon Dioxide (‘CO’) Pipeline Project; AGIs; utilities; construction laydown areas; access works; and other associated and ancillary development.

3. In accordance with Section 48 of the PA 2008 and Regulation 4 of The Infrastructure Planning (Applications: Prescribed Forms and Procedure) Regulations 2009 (as amended), the Applicant has a duty to publicise the Proposed Application. In accordance with those provisions, this notice also summarises the Proposed Development and explains where the consultation documents (the ‘Consultation Documents’) can be viewed.

The Proposed Development

4. The Proposed Development Site (the ‘Site’) comprises land at, and in the vicinity of, the Connah’s Quay Power Station Site, Kelsterton Road, Connah’s Quay, Deeside, CH5 4BP. The Site includes land within the administrative area of Flintshire County Council in North Wales and also within the administrative area of Cheshire West and Chester Council in England.

5. The Site comprises a number of areas, including the ‘Main Site’, encompassing the Connah’s Quay Power Station Site which would be the location for the new CCGT with CCP, and a number of corridors of land for electrical grid connection, carbon dioxide and water connections, and other areas of land for construction laydown, biodiversity enhancement area and access works.

6. The Main Site is approximately 56.5 hectares (‘ha’), with the entire Site extending to approximately 186 ha.

7. National Grid References for the Site are provided below:

• Main Site (mid-point) – 327347, 371374

• North – 316076.4684, 381767.9826

• East – 340774.572, 377392.988

• South – 328895.9, 370177.1

• West – 315257.3468, 381072.3789

8. Plans are available from 8 October 2024 until 19 November 2024 within the ‘Consultation Documents’ (see further below) on the Applicant’s consultation website under the ‘Documents’ tab: https://uniperuk.consulting/cqlcp/ showing the proposed Indicative Site Boundary.

9. The Proposed Development comprises the following elements:

a) Demolition works at the existing Power Station Site, including demolition of the existing GTP, AGI, store buildings and contractors’ facilities.

b) A CCGT electricity generating station of around 1,100 MW and up to 1,380 MW net electrical output with CCP and ancillary buildings and structures within the Main Site. The CCGT with CCP plant will comprise up to two new 'Trains’.

c) Associated Development, including:

i. Proposed Carbon Dioxide (‘CO₂’) AGI – which will be located within the Main Site.

ii. Repurposed CO₂ Connection Corridor – the export of CO₂ will utilise approximately 3 km of an existing natural gas pipeline. It includes a buffer zone of up to 100 m width. Some physical works may be required to the Repurposed CO₂ Connection within the Main Site to connect to the Proposed CO₂ AGI and within the Proposed CO₂ Connection Corridor to connect to the Proposed CO₂ Connection. Studies are ongoing to determine the need for and nature of any physical works within the Repurposed CO₂ Connection Corridor.

iii. Proposed CO₂ Connection Corridor – captured CO₂ emissions from the Proposed Development will be discharged from the Repurposed CO₂ Connection Corridor, via a new circa 350 metre pipeline spur (the Proposed CO₂ Connection) into the proposed Flint AGI (which is part of the proposed HyNet CO₂ Pipeline Project) and then into the HyNet CO₂ Pipeline.

iv. Water Connection Corridor – cooling water for the Proposed Development will be abstracted from and discharged to the River Dee, in line with the current process for the existing Power Station. This may require new infrastructure or use of existing infrastructure.

v. Electrical Connection Corridor – a new connection will be required from the CCGT plant to the Applicant’s existing banking compound. The existing electrical connection from the Applicant’s banking compound is expected to be used to connect the Proposed Development to the existing Connah’s Quay Substation located south-east of the Main Site.

vi. A Construction Laydown and Indicative Enhancement Area.

vii. Accesses and access works.

d) Further associated development comprising such other works or operations as may be necessary or expedient.

10. All of the above elements will be included in the Proposed Application.

11. The Development Consent Order sought would also authorise, if required, the permanent and/or temporary compulsory acquisition of land and/or rights in land required for the Proposed Development; the extinguishment and/or overriding of easements and other rights over or affecting land required for the Proposed Development; and/or the temporary occupation of land required for the Proposed Development; the application and/or disapplication of legislation relevant to the Proposed Development as may be required; permanent and temporary changes to the highway and public rights of way network as may be required; tree and hedgerow removal; the construction, operation and maintenance of associated development, including, but not limited to those items listed in paragraph 9; and such ancillary, incidental and consequential works, provisions, permits, consents, waivers or releases as are necessary and/or convenient for the successful construction, operation and maintenance of the Proposed Development.

Environmental Impact Assessment

12. The Proposed Development is ‘EIA development’ for the purposes of The Infrastructure Planning (Environmental Impact Assessment) Regulations 2017 (the ‘EIA Regulations’) and so the Applicant is required to carry out an Environmental Impact Assessment (‘EIA’) of the Proposed Development and submit an Environmental Statement (‘ES’). Accordingly, the Applicant has notified the SoS in writing under Regulation 8(1)(b) of the EIA Regulations that it intends to provide an ES in respect of the Proposed Development and this will form part of the Proposed Application for development consent.

13. Information so far compiled about the Proposed Development’s environmental impacts is contained in a Preliminary Environmental Information Report (‘PEIR’) and summarised in a Non-Technical Summary (‘NTS’). The PEIR and NTS of the PEIR will be made available as part of the Consultation Documents.
