Elewit - the technological platform of the Red Eléctrica Group


SAGA is an advanced information system for electricity grids, which optimises asset management strategies for TSOs and DSOs to extend asset lifespan through smarter, predictive and risk-based maintenance, reducing maintenance safety risks, impact of transmission assets on the surrounding environment and costs, increasing security of supply and creating synergies between workstreams.


• Creates a holistic overview of all assets’ conditions in a user-friendly interface (reduction of 10-30% of maintenance costs and 15-40% of person-hours)
• Prioritises and optimises asset maintenance planning through algorithms
• Integrates multiple business areas, e.g. vegetation management (streamlined felling & pruning planning, fire risk mitigation, consideration of protected zones & bird-crossing areas), outage plan, customised reports for decision-making processes.

In response to the myriad challenges presented by the energy transition and asset managers’ reported difficulties, the three modules of SAGA work together to enable greater system asset management capabilities. MANINT: addresses assets’ individual technical optimisation; VEGETA: manages data on vegetation species management; OPTIMIZA: uses data from other modules to simulate ac-tivity plans and prioritise maintenance and replacement activity. The result is a holistic “whole-grid” view, which allows for the optimisation of all maintenance and replacement activities.
