What is Enterprise Energy Management ?

"What you can't measure you can't manage"

Advanced Measurement and Control is the basis for the application of a comprehensive energy efficiency approach.
The fundamental principle is that energy and other utility are direct costs that should be monitored and controlled in the same way as other production related costs such as labor and malt.
Today's complex energy infrastructure , supply, load and usage require complex energy management system that can provide the tools needed .
Enterprise Energy Management is the solution
New enterprise energy management systems offer businesses - on both the supply and demand side of energy - the key to controlling the cost, quality and reliability of the power delivered or consumed. An EEM system can be thought of as a layer of energy I.T. (information technology) that rides atop a company's entire collection of energy assets. It is a permanently installed system, running 24 hours a day, that provides all the information and control capabilities necessary to enable management, accounting, engineering, and maintenance personnel to make the best decisions, and to take proactive control of energy assets, throughout their entire enterprise.

Typical Components

EEM systems consist of a collection of networked software and intelligent, microprocessor-based devices that can span widely dispersed geographic locations and multiple points within each site. To accommodate growth, the system should be modular and scalable. The distributed devices are located at key points throughout the power supplier or power consumer's enterprise; for example, at the electrical service entrance to each facility, and inside each power substation or facility on critical feeders, equipment and loads. Due to the critical nature of the applications, these should be highly reliable, industrially hardened devices that are protected against tampering, and have non-volatile memory to retain energy and power quality logs in the event of a communication failure. critical points should also have the ability to determine compliance with applicable power quality standards.

Additional inputs, outputs and automated control functions should be provided to import pulse data from other utility meters (gas, water, etc.) and to monitor and control the status of external equipment. Multiple communication ports that directly support a variety of industry-standard protocols will allow for information sharing with billing and automation systems . The remote devices are connected over a sophisticated communication network to head-end system software .
