OSAKA: System development and asset management under restructuring

Summary

In many developed countries the electricity infrastructure contains ageing assets. Because of the need of a continuing operation and higher load factors on the network, the opportunities for replacement or refurbishment are limited. These must be regarded as an opportunity to review the structure of the system and to consider the design and development required to meet the new requirements, taking advantage of new available technologies: HVDC, FACTS, cables, etc.

The symposium examines assets management issues and assesses strategies for overhauling existing systems, taking into account the impact on market operation, on supply security and environment.
