Worley was one of two contractors selected in December 2024 to design and submit plans for the site as part of the Front End Engineering Design (FEED) competition.
Uniper is working towards a potential capacity of up to a maximum of 1.38GW low-carbon power, developed in two phases. From completion of phase one, the project could supply enough electricity to power the equivalent of around 1.1 million homes a year. Phase one could potentially be operational from 2030.
This is the next step in the potential development of CQLCP which, if consented and developed, would be constructed on land next to Uniper’s existing power station. A Development Consent Order (DCO) application was submitted by Uniper in August 2025, with the decision expected in the coming months.
The proposed new power station would connect into nearby CO2 transport and storage infrastructure as part of the HyNet industrial cluster, enabling the captured CO2 to be transported to permanent offshore storage facilities in repurposed depleted offshore gas fields. The first phase of the project could be operational from 2030.
Jim Shaughnessy, President, Major Projects & Programs, EMEA, Worley, said, “We’re pleased to continue working with Uniper on the strategically important Connah’s Quay Low Carbon Power Project. Together with Siemens Energy, SLB Capturi and our construction partners, we have assembled an integrated team combining technology, engineering and project delivery expertise."
