Customized Energy Solutions (India)

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.
