As part of a contract, including the uprate of two 9F gas turbines and a six-year maintenance support agreement, the upgrade includes the first UK installation of GE’s dual fuel DLN2.6+ combustion system technology. The company claims it can reduce nitrogen oxide emissions by 40 per cent.

The DLN2.6+ technology allows the gas turbines to be operated at reduced power during off-peak periods while maintaining low emissions levels. This saves fuel consumption and leads to reduced operating costs.

DLN2.6+ technology is already in use at power plants elsewhere in Europe, notably in Italy, where emissions regulations are particularly stringent.

The uprated 9F gas turbines are scheduled to be in commercial operation by the third quarter of 2012. The station’s gas turbine control system also will be upgraded with a GE Mark VIe control system.
