Calon Energy has selected GE to upgrade its Sutton Bridge Power Station in Lincolnshire with a broad range of hardware and software technologies to increase power production, improve efficiency and flexibility, and reduce its operating costs. The 800-megawatt (MW) natural gas-fired combined-cycle power plant provides electricity to the East Anglian region of the United Kingdom, and the upgrades will help increase the competitiveness of the plant in the country’s challenging power industry.
Sutton Bridge’s two existing GE 9FA gas turbines and a D-11 steam turbine will be upgraded with multiple applications from the OpFlex* controls software suite, a Dry Low NOx 2.6+ combustor, and Advanced Gas Path (AGP) technology solutions. The project represents the first 9FA AGP upgrade in the U.K. These enhancements will help the power station become a far more flexible, reliable, and efficient plant able to meet the demands of the U.K.’s power needs today while also being able to respond to the requirements of the future with the introduction of the U.K. Power Market Balancing Mechanism. Sutton Bridge also will benefit from additional availability to generate power with extended periods between planned outages with these upgrade solutions. The project is expected to begin in mid-2016 and be completed some months later.
The Sutton Bridge Power Station is adjacent to the River Nene and is located approximately two miles from the village of Sutton Bridge in Lincolnshire. GE’s upgrade package will include OpFlex Enhanced Transient Stability, AutoTune, Variable Load Path, Cold-Day Performance, Extended Turndown, Variable Inlet Bleed Heat and Variable Airflow and Steam Turbine Agility applications, steam turbine thermal blankets for improved cold-start capability and upgrades to balance-of-plant equipment to allow for additional performance improvement.
GE has managed the operation and maintenance (O&M) of the Sutton Bridge Power Station since 2013 under a multiyear services agreement. Currently, GE has more than 30 O&M people on-site managing the facility on behalf of Calon.
