January 2004 - ABB is providing a complete turnkey EBoP solution for the Open Cycle Gas Turbine plant at Didcot Power Station in Oxfordshire
March 17, 2012 – ABB, the leading power and automation technology group, has been awarded a major contract by energy company RWE npower to supply a turnkey electrical balance of plant (EBoP) solution for the repowering of the Open Cycle Gas Turbine (OCGT) plant at Didcot Power Station in Oxfordshire.
The Didcot OCGT plant, comprising four diesel fired turbines with a total capacity of 100 MW, is designed specifically for peaking operation. During periods of high demand, it offers a flexible, reliable and fast-responding source of additional capacity to provide support for the National Grid. In the repowering project the OCGT plant’s electrical control and protection systems are being upgraded to the very latest operational standards.
ABB’s turnkey EBoP solution for the Didcot OCGT power plant includes the design, engineering, supply, installation and commissioning of all the equipment and civil engineering required to control the electrical power generated by the gas turbines and to deliver it safely and reliability into the local grid. Key systems to be supplied include an 11 kV substation based on ABB’s Unigear ZS1 switchgear fitted with VD4-G Generator Circuit Breakers, auxiliary transformers, and the protection and control equipment including the control system that will interface with the DCS at Didcot B CCGT station.

‘The Didcot OCGT project continues to build ABB’s growing momentum within the UK’s EBoP sector’, said Tony Rooney, Head of ABB’s UK Power Generation business. ‘ABB has established a global reputation as a key supplier of turnkey balance of plant projects for a wide variety of plant types, such as oil & gas fired combined cycle power plants, coal fired boiler power plants, biomass and hydro power plants. This project for RWE now provides the ideal opportunity for us to demonstrate our capability for OCGT plant.’
