THE PLANT DATA MANAGEMENT SYSTEM

What was originally a software package developed to ensure that our project received the appropriate payment for each kilowatt hour sold, and plant revenues were totally accountable for both regulatory and business purposes, has grown over the years to become a detailed management information system. The PDMS tracks production, revenues, costs for consumables, regulatory compliance, performance, and plant specific engineering and management items. This software has been written to provide the owner, plant manager, and operators a comprehensive set of reports that are automatically produced with information acquired through a plant’s distributed control system.
