Current state & stage in application lifecycle PowerFactory is expected to remain as our key modelling tool, but with ongoing investment to ensure appropriate software modules developed by DigSILENT are added to the current system. DigSILENT is also used as a modelling tool by our protection engineers for grading field protection. Modern SCADA systems include Historian functions so with the planned investment in the SCADA replacement and the newly built data lake there is no need for a dedicated Historian in the long term. This is will be confirmed through the planned SCADA replacement project. Strategy & Plan for Period The introduction of new technologies (e.g. Solar PV and storage batteries) could lead to the injection of energy into the LV network from external sources. This was not envisaged when the LV network was designed. To manage this risk, we are increasing our visibility of the LV network by the following: • Increased demand and voltage monitoring capability of the LV network • Improved analytical tools. Field data providing demand and voltage information needs to be filtered to identify those parts of the network likely to breach regulatory or ratings limits. This will enable remedial works to those targeted areas. • Improved capability, since our network model needs to cater for new technologies to be modelled
