Maintenance Management in an Electric Power Transmission Company Key Technical Indicators
The high development costs of the power transmission systems and the increasing quality demand by customers and society itself, makes the maintenance management of a power transmission grid a key element in the continuity and reliability of the electrical supply. This is not only due to the need to minimize failures but also to the increasing limitations imposed on grid operators regarding the unavailability of assets for maintenance. In recent years, many countries have seen that the development of the high voltage transmission systems has not gone hand in hand with the rise in demand. The present challenge to be faced is how to manage maintenance at reasonable costs and risks to improve the quality of the service offered to the customers, while reducing the scheduled unavailability of assets. In the market, there are many different management strategies that are aimed at industries, in which maintenance is a link in the production chain. In the case of an electric power transmission utility, even though the management may have similar patterns to the ones in other activities, maintenance and grid operation are the primary function of the utility. That is why they have their own special characteristics and complexity. Firstly, it should be noticed that, unlike other industries, all the assets owned by a transmission company are static and, in a power transmission grid, failure does not only depend on maintenance since lines are subject to weather and environmental factors. Secondly, indicators that may be useful to measure maintenance effectiveness in other activities are not useful to manage the maintenance of a high voltage transmission system. The amount of assets used in an electrical energy transmission utility added to the high cost and the economic and social consequences of a failure demand a constant and significant improvement of the management system. There should be a differentiation between a management system that allows the organization of the operating and maintenance activity – such as ISO 9001-2000-, and the techniques applied to choose maintenance tasks like RCM. Success is not assured solely by the mere application of an organized management system; it must be complemented by the correct selection of maintenance strategies. This is achieved by studying assets in their operational context and failure mode and consequences in order to determine what should be done as regards maintenance.
