Introduction
• Until recent past • Reactive Energy Management practices
• The cost of metering was prohibitive.
• Delayed pricing information and inadequate metering
• Now • Explosion of cost effective tech solutions in past decade
• Energy Managers have access to EMCS/SCADA systems
• Energy Information exchange facilitated by AMR
• Additional incentives available through Price Responsive Load Management programs
Energy Usage Analysis
• Analysis of the energy billing history, long-term trend analysis of usage, regression analysis by kWh and kW for weather normalization
• simple spreadsheet based tools or sophisticated energy information systems
• Customized reports: 15-min, hourly, daily, month-to-date and year-to-date
• Can use spreadsheets or online s/w such as ABB’s Energy Profiler
Monitoring
• Real time usage information opens up avenues for monitoring the energy costs.
• Automated and accurate reporting and analysis through internet.
Daily comparison of current load
profiles with expected load shapes
based on historical data.
Controls
• Possible for real time control of cumulative peak of different facilities. e.g. Stapled Inc., Ca
• EM can do Trend-log analysis w.r.t. system design.
Evaluating energy use data can identify deficiencies in control consistency.
Weather regression can be used to evaluate such patterns by comparing on a normalized usage.
Benchmarking
• Gives measures of energy performance, help track changes, and identify best practices.
• Compares the Energy Utilization Index (EUI) against standards.
• Enables the Energy Managers to make accurate and predictable adjustments to operational practices.
Diagnostics
• Diagnostic capabilities allow categorizing operating data into classes of energy usage.
• New s/w use learning control and pattern recognition techniques
Requires trained, experienced
technical personnel to ascertain
how to use the operational data
to develop new energy cost
savings techniques.
