Schneider Electric’s Critical Power Competency Center moved beyond its status as sole equipment provider to become an engineering partner for RagingWire. This gave RagingWire access and insight into all the various engineering and design resources within Schneider Electric as a whole and provided RagingWire with a unique competitive advantage, more energy and space efficient operations with increased reliability without adding more equipment and better power monitoring, .

Just like every other industrial enterprise, the Hershey Company's candy manufacturing plant in Stuarts Draft, VA, needs electrical power. Unlike many other enterprises, plant management has taken a proactive approach to its power usage. In the late 1990s, due to a plant expansion, Hershey's corporate engineering arm decided to bring on a power monitoring and control system. Since then, the benefits of that decision,utilizing Square D Powerlogic products from Schneider Electric, have gone far beyond analysis of power usage and quality and a better understanding of how the electrical distribution system is functioning at any given time.

Stephen Pauli is with Bayer Material Science in Baytown, Texas. This article first appeared in its original form at the 2003 IEEE/IAS Petroleum and Chemical Industry Technical Committee Conference. The IEEE Industrial Application Solutions published this paper in the Volume 11, Issue 2 in 2005 and granted permission for this posting. The paper is a guide to specifying, justifying, and installing substation monitoring and control systems based on Bayer's experience. Between 1996 and 1999, a large chemical firm made US$1 billion in capital investments, adding production capacity and doubling the site load to 220 MW. This growth strained the capacity of critical substations to carry loads had its companion transformer failed(in a typical main-tie-main arrangement). In parallel to a year 2000 cogeneration agreement, this firm funded a US$13 million project to improve the electrical distribution system infrastructure. This project installed a third 138-kV yard, a 138 kV/34.5 kV 2 × 64 MVA substation, and a satellite 2 × 34 MVA 13.8 kV substation.
