• One PI Module for the Generation portfolio• A sub-module of the Portfolio Module corresponds to a Generation Unit.• A Unit Module corresponds to a Unit class.• Various Unit Parameters form the aliases/properties of the unit module
and are accessed that way from the code.• Very easy to add/delete units from the portfolio.
PI-Future at Conectiv• Have recently installed a new Generation
Management System and PI is the data historian for it.
• HA-PI system that has interfaces with our corporate PI system.
• Plan to convert every PI historian to an HA system
• Looking to leverage some of the web-based technologies at offer.
