The ERIS (Evaluation of Reliability Index for Electric Systems) quality indicator developed by Axpo provides you with an instrument for systematically determining and measuring supply security. ERIS supports you in the planning, development and operation of your electricity grid. For grid operators, the operation of an efficient, secure grid is increasingly becoming key focus. The importance of the quantitative assessment of supply security increases with increasing cost pressure.
Innovative technology to quantify security of supply
Due to the effort involved in conventional reliability calculations and the increasing complexity and dynamics of electricity grids, Axpo has developed and patented the grid quality indicator ERIS to assess the security of supply.
To calculate supply security, the methodology uses existing load flow, topology and condition parameters and enables investments to be linked to a value for supply security.
Since 2016, Axpo has successfully used the ERIS quality indicator for both large high-voltage and medium-voltage grids. NEPLAN, the IT manufacturer, was determined as the ideal partner to ensure that other network operators also benefit from the ERIS methodology. Within the network calculation program, the quality indicator is calculated at the push of a button. Network expansion and renewal measures can be identified efficiently and different variants can be compared transparently. By selecting the planning principles, network operators can adapt the assessment to their specific requirements.
