Owner’s Engineer CCGT Plant Modification

Enabling bi-fuel operation

Client RWE npower
Location United Kingdom
Expertise Owner’s Engineer, Combined Cycle Gas Turbine Power Plant, Fuel Flexibility, Dual Fuel Configuration


The 1,650 MW combined cycle gas power station Staythorpe between Southwell and Newark-on-Trent in Nottinghamshire runs primarily on natural gas. In order to upgrade the station to  liquid fuel ability, hence increase operational flexibility (the project), we were assigned to act as owner’s engineer and technical adviser on behalf of RWE npower for the project. 

We were the lead firm responsible for construction supervision and EPC contract administration duties. Other services included design review, assistance with procurement, bid evaluation and warranty management.

Power Plant Modernization

Over the last two decades, we supported various power plant modernization projects within the RWE Group. Aiming to keep the RWE generation fleet profitable and competitive, we assessed the techno-economic potential of upgrading plants by improving existing gas-fired plants (especially in UK / NL) or repowering and modernizing the coal-fired fleet in Germany. We applied modern technologies on gas turbines or water steam cycles, upgrading generators to enable those extra MW’s being safely and efficiently generated and supplied to the grid. We also supported the roll-out of O&M solutions that brought major cost savings to the total fleet. 

Acting as owner's engineer and technical advisor on behalf of the RWE Group we were responsible for engineering, procurement, construction supervision, project management and contract administration duties. RWE's key projects we supported in the last 10 years include:
