Web-based business modules called Power System Engineering Modules (PSEM) are used for transmission assets and operating statistics management under Transmission SBU(Strategic Business Unit). It was decided to revamp the existing PSE modules into a more functional framework incorporating the workflows in substations, transmission offices, and related offices with the integration of the Permit Management software, protection and communication applications, SAMAST (under development at SLDC, Kalamassery) and SAMAGRA software.
