Rough redevelopment owner's engineering
Centrica Energy Storage+ (CES+) aim to redevelop the Rough field into the UK’s largest hydrogen-ready gas storage site.
Our team initially provided engineering and technical support to the early phases of the Rough redevelopment project. As the project developed, the team’s support services were extended into FEED as part of the PMT.
The team’s concept optimisation approach was instrumental in maximising value in the early phases of the Rough redevelopment. Beyond FEED, the team’s value improvement practices identified substantial further project cost savings.
Scope of Work
Owner’s engineering and technical services, including:
- Project management
- Owner’s engineering at concept, pre-FEED, FEED and beyond
- Concept optimisation and value improvement
- Technical assurance and design verification
- Cost estimation, risk management, project economics
- Cost & Schedule Risk Analysis (CSRA)
- Reservoir and Integrated production modelling for both natural gas and hydrogen project phases
- Technical Authority for pipelines and submarine cables
- Interface management
- Landfall and materials technical assurance
- Technical support for government consultations
“A redeveloped Rough will be fast acting, responsive and capable of delivering the vast amounts of energy the UK needs in a more flexible and dynamic system.”

Key highlights
- Rough is a nationally important asset that can work for the UK: proven, scalable and capable of strengthening UK energy security while helping protect consumers from volatility.
- The Rough redevelopment will quadruple the UK’s gas storage capacity and will have a higher gas production rate than any current gas store.
In addition to technical support, Elemental Energies provided comprehensive corporate support, including project implementation planning, scheduling, organisational readiness, execution strategy, stage gate reviews, audits, scope development, and bid documentation preparation and review.
This combination of technical expertise and extensive experience enables the delivery of demonstrable value improvements during the early phases of projects.
