A modular power plant comprises an internal combustion engine coupled to an electrical machine. The electrical machine may be used to start the engine and to generate electrical energy. The power plant is provided with an electronic control and protection system comprising an electronic processing and control unit arranged to operate in a first mode when the power plant is used alone, and in a second mode when the power plant is used together in a coordinated manner in an installation comprising a further n power plants. In this second mode of operation the processing and control unit may act as a master unit for controlling and coordinating the operation of the processing and control units of the other n power plants in a predetermined manner, or as a slave unit controlled by another control and processing unit of one of the other n power plants. Means are provided for assigning the roll of master unit to one of the control and processing units of the n+1 power plants.
