UK Power Networks (UKPN) is an electrical distribution company that covers London, Southeast England, and East England covering 30,000 square kilometers and 8.2 M metered customers. As a leader in this market and responsible for one of the largest population centers in the world, UKPN is leading several project initiatives to meet the regulatory and market requirements including the digitalization of the grid. These efforts have led to the need for an operational data management and analytics system for Operational Technologies (OT) at an unprecedented scale. Each meter and device must be contextualized in an asset hierarchy as the relationship is key to make the data useful. To assist UK Power Networks on it journey, they have selected AVEVA’s PowerRunner on AVEVA PI System to be the data and analytics’ platform to assist in driving them to success during the increase of digitalization and DNO to DSO transition.
