Key benefits


RoSPA Gold Awards

Project delivered within strict environmental benefits

Facility has capacity of 160 million cubic metres

Daily withdrawal rate up to 22 million standard cubic metres

Plant can start up in just 30 minutes

Costain’s scope included the engineering, procurement and construction management for the gas processing plant and associated infrastructure, including modification works to the wellheads to allow the caverns to be prepared for gas trading.

The project was delivered in an integrated team combining the knowledge, experience and expertise of E.ON, Costain and supply chain partners from across UK and Europe.

Environmental considerations

The facility was built in the heart of the Cheshire countryside, in an environmentally sensitive area. The project was delivered within strict environmental guidelines governing noise, visibility and protection of wildlife, and with due consideration to the local community.

This is a major achievement for the project team who have successfully addressed a number of complex technical and engineering challenges in delivering the operational facility at Holford. We would like to thank the Costain team for its effort and commitment in achieving this important handover milestone.
