Determination of Budgets in Asset Management for Maintenance and Renewal Measures based on a Cross-Sectoral Condition Assessment

Abstract:
Optimal management of equipment is essential in order to counter the rising cost pressures resulting from increased prices and the financial burden of the energy transition on the level of distribution system operators. The demand for renewal of equipment which is not replaced as part of capacity expansion planning should not be neglected. Implementing a condi-tion-based strategy can be an important part of the solution for asset management. It is currently possible to carry out a cross-sectoral condition assessment of equipment, which can overcome a strict separation in the consideration of individ-ual equipment and sectors. This holistic condition assessment is initially used to determine the necessary budgets for maintenance and renewal across all considered sectors. These are necessary in the long term in order to maintain the reliability of supply in the grids at the current high level. As the necessary calculated budgets are often only partially available at present, individual equipment can be prioritized for maintenance and renewal measures. In this prioritization, various criteria can be entered that expand the technical condition to include other important aspects of grid operation. In the use case, a necessary budget for maintenance and renewal measures is determined for a real grid area. This budget is allocated differently to the equipment and sectors in various variants using different influencing factors. Thereby diverse targets can be weighted diversely, e.g. maximization of the reliability of supply or minimization of civil engineering costs.
