The privatisation of the utility sector has brought enormous changes in the way these markets operate and consumers buy their services. The electricity industry comprises a large number of private companies competing fiercely to sell electricity directly to industrial, commercial and domestic consumers. The generators that provide the power, the energy and the system ancillary services equally compete on price to produce electricity competitively into the market. This has brought with it new opportunities in the way electricity power plants need to be managed and controlled. Since privatisation, the delivery of power, energy and other ancillary services has been subject to a number of complex contractual obligations and monitoring procedures and these are changing continually. The pressure of competitive pricing places a greater emphasis on plant availability, generation efficiency, plant life and maintenance costs. The chapter describes the authors' experience of how their company has responded in this arena. Initially, it describes a number of plant management and control functions that were previously performed manually and have been automated. This has involved detailed analysis and re-design of the operator tasks. It has also required the design of many new operator interfaces and automatic control functions.
