Calon Energy selected General Electric (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 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 technology solutions. The project represents the first 9FA AGP upgrade in the U.K.
These enhancements will help the power plant 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 about 2 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 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.
With more than 25 years of experience in O&M of power plants, GE currently manages more than 11 GW at 22 sites in 11 countries. GE’s global resources and fleet expertise enable it to provide complete plant services and management, along with sharing best practices and technical knowledge with power plant owners.
