Project plans
The Connah’s Quay Low Carbon Power project is at an early stage of development, and our proposals may be subject to change, but it is initially expected to consist of:
- A new 1.1 gigawatt (GW) combined cycle gas turbine (CCGT) power station
- Carbon capture technology to enable carbon dioxide (CO₂) emissions from the CCGT to be collected
- A connection to nearby CO₂ transport and storage infrastructure as part of the HyNet industrial cluster
Key facts about our proposals
- CQLCP could support the decarbonisation of the National Grid, providing power when there is insufficient generation from wind and solar
- Our Connah’s Quay site is the ideal location for a new low carbon power station, having had electricity generation on the site since the 1950s
- Critical infrastructure needed for electricity generation is already in place, including connections to the national electricity grid and a pipeline that can be repurposed and used to transport CO2
- When fully operational CQLCP could generate enough low carbon electricity to power the equivalent of up to 2.8 million homes a year
- When fully operational, and at maximum output, CQLCP could capture and store up to 3.7 megatonnes (Mt) of CO2 per year, contributing to the UK’s transition to net zero
- CQLCP could contribute to economic growth, protecting approximately 60 high-skilled technical jobs and creating new opportunities during construction and through the wider supply chain
- We will continue to maintain the Site of Special Scientific Interest (SSSI) on our land and will work with a range of stakeholders to protect and enhance local habitats
The Connah’s Quay site
Uniper is land owner of the 98 hectare Connah’s Quay site, currently occupied by our existing unabated gas-fired power station. The proposed new development will be located on the same site adjacent to the existing power station.
The map below shows indicative locations for the infrastructure that would be built on our site, as part of the proposed CQLCP project. Please note that these plans are still in an early stage of development and are subject to change following feedback and consultation with national statutory bodies, local authorities and the local community.
What will the new facility look like?
The final design will be determined during Front End Engineering Design (FEED), but we are proposing to build a new combined-cycle gas turbine (CCGT) power station with carbon capture technology.
What is carbon capture and storage?
Carbon capture and storage (CCS) is a key part of the process to reduce carbon emissions in energy generation. It involves the removal and capture of CO₂ from power plant emissions, transporting it away to be securely stored underground, often in aquifers or depleted oil and gas fields.
CCUS also refers to carbon capture and storage but with the ‘U’ referring to utilisation of the captured CO₂. Captured CO₂ can be used for a variety of industrial purposes, such as the production of synthetic fuel and low carbon building materials, or in the food and beverage industry.
