In this paper we consider the mixed telephone network of electric power utility consisting of IP, ISDN and Power Line Carrier links. Very important demand in the network is high availability. The central detector of IP and ISDN link failure (pre-alarm) is presented. The detector function is based on the prolonged response time of the network in the case of IP and ISDN link failure. We define undesirable events in the detector operation: false pre-alarm and miss detection, and we derive the expressions for their probability calculation. It is indicated that centralization of this detector is merit, which facilitates testing of the whole network from one location.

This chapter will present an overview of the challenges presented to modern power utility companies and how many organizations are facing particularly pressing problems with regards to an ageing workforce and a general shortage of skills; a situation that is anticipated to worsen in the future. It is proposed that knowledge management (KM) and decision support (DS) may contribute to a solution to these challenges. The chapter describes the end-to-end processes associated with KM and DS in a power utility context and attempts to provide guidance on effective practices for each stage of the described processes. An overview of one particular power utility company that has embraced KM is presented, and it is proposed that the function of asset management within power utilities in particular may benefit from KM. The chapter focuses not only on KM techniques and implementation, but, equally, if not more importantly, on the various cultural and behavioural aspects that are critical to the success of any KM/DS initiative.

The concept of “Cloud computing” became very interesting in recent years because it enables optimization of resources used and costs paid for it. Considering all advantages, this approach is applied widely in business systems of general purpose. In recent years, in literature it is possible to find considerations related to application of this approach in corporate systems as electric power utilities. Having in mind that such types of systems represent infrastructure ones that have great impact to the security of people and utilities, a very important question related to information security should be seriously considered. This chapter discusses advantages and disadvantages of application of cloud computing in electric power utility systems.

An electric-power utility was first established in Charlottetown in 1885, but less than fifteen years later the question of its municipalization was being considered. High rates and poor service brought the issue to a head in 1904, and the following year the citizens voted heavily in favour of public power when the question was submitted to them in a plebiscite. Civic politicians proved to be more interested in lower rates than in municipal ownership, however, and when the power company, under duress, promised better but cheaper service, the idea of direct ownership of the utility by the city was quickly forgotten.
