Durham College Cuts Energy Usage While Expanding Facilities
Durham College needed more electrical data in order to manage energy saving projects. Following work completed by Square D POWERLOGIC, the the base load dropped from 600,000 kWh per month in 1989 to 400,000 kWh per month in 1997. The average demand peaks were also reduced from 1,600 kW to 1,000 kW over the same time period. As a result of these reductions the College realized a cost savings of approximately $400,000 in 1998.
Pentagon Decides on Square D POWERLINK For Major Renovation Program
The Pentagon, headquarters of the United States Department of Defense, is moving forward with the Pentagon Renovation Program (PENREN), a seven-phase, 20-year, $1.2 billion project. Square D, a division of Schneider Electric, was awarded many of the more than 300 individual contracts required for this massive renovation project.
Chemical Plant Credited for Power Factor Penalties
A PowerLogic system installed to help keep an eye on costs helps uncover costly errors in the plants utility metering. After reviewing data from PowerLogic System Manager Software, a company executive discovered a major discrepancy between system manager reported data and the utility bill in regards to power factor. Further investigation revealed an uncalibrated utility meter resulting in a $250K credit for past power factor penalty charges.
A PowerLogic power monitoring and control system that was installed and tested at Helen Hayes Hospital in West Haverstraw, NY helps the hospital monitor and test their 1600KW generator. During an outage, the PowerLogic system monitors generation, sheds load to avoid overloading, and re-loads as generation recovers. The system also monitors essential vital signs of the hospital's entire electrical system, and records information necessary to help document JCAHO compliance during generator testing.
Refinery Identifies Power Quality Problem Causing Shutdowns
A petroleum refinery was experiencing unexplained periodic trips of five large synchronous compressor motors. Each trip resulted in approximately $150,000 in costs due to production losses and Environmental Protection Agency (EPA) fines. After installing a Square D PowerLogic system, the refinery personnel were able to ascertain the cause of the compressor trips and the problem was corrected.
Computer Manufacturer Cuts Energy Costs 20% Using Power Management Equipment
A global supplier of computing and imaging solutions, facing forced utility cutbacks needed a means to quickly shed non-essential electrical loads to avoid a total shutdown. By implementing a system that could shed 15% of the total connected electrical load, within 15 minutes after receiving a call from their local utility, forced outages could be avoided and thus preserve critical power needs.
Concessionaires at Giants Stadium began adding additional electrical equipment, although the electricity cost formula for concessions and suites remained unchanged. It was apparent the stadium was losing out on reimbursable electricity usage. The stadium's power system had four major needs: * Submeter for accurate billing to concessionaires (40) and luxury suites (72) * Monitor quality of power and harmonics, to avoid disruptions; * Estimate future usage and loading * Centralize power management to monitor and report both real-time events and historical usage data.
Chemical Manufacturer Controls Expensive Demand Charges
A chemical manufacturing company needed a more efficient and controlled way to ensure compliance with an automated Time of Use/Dispatch Power rate schedule from their utility. Plant personnel however, had no way of knowing power usage and were unequipped to shed load when directed by the utility system. A PowerLogic system with circuit monitors was installed and programmed to automatically identify which areas of the manufacturing process needed to cut back usage when called on. Based on programmed setpoints the circuit monitor for each area signaled operators to trim power usage. The PowerLogic system provided a simple solution for avoiding expensive demand charges.
Major Pharmaceuticals Company Monitors Total Utility Metering
A major pharmaceuticals company, established a program to monitor all utility usage in an effort to reduce energy costs. With the help of Square D PowerLogic, the organization was able to meet these goals and build a foundation for future savings opportunities.
