Energy Studies

osscarIMG_0002Energy Studies are used to evaluate specific process and Electrical Distribution System improvements to uncover the potential electricity savings that can be achieved if energy saving upgrades are done at your facility. Additionally, Energy Studies help develop the business case for energy efficiency projects you are looking to undertake.

The information gathered from the Study will also identify potential capital incentive project opportunities that may exist that you weren’t already aware of. Opportunities exist in systems that aren’t running properly, that are using old equipment or those that require optimization.

Preliminary Engineering Study (PES) Overview

The Ontario SaveON program, through the Independent Electricity System Operator (IESO) and the Local Distribution Companies (LDCs), offer up to $10,000 in incentive funding for completing a Preliminary Engineering Study for a key process or single industrial system that will identify opportunities for process improvements that can reduce electricity use. A Preliminary Engineering Study should be done when you are aware of the potential for electrical savings but you are unsure of the approach to achieve the energy savings. Similar attractive incentives are available in other provinces and jurisdictions.back to top

Energy Study Objectives & Scope of Work

  1. To compile and analyze 12 months of historical electrical billing data;Billing Graph
  2. To survey and make a line drawing of the electrical distribution system;
  3. To survey, identify and match major loads to electrical panels;
  4. To document and estimate operating hours and annual electrical consumption of all major loads;EndUse %
  5. To determine possible strategic metering points throughout the plant and design a smart-metering system for monitoring and targeting (M&T) load usage and energy consumption in real time;
  6. To do a cost-benefit analysis and determine ROI of a possible Monitoring and Targeting System installation. Potential Operational and Maintenance reduction in kWh:          10% - 20% per year; Meter Hookup - Scotsburn Truro - IMG-20130314-00142a
  7. To do measurements, load power logging and load simulations with the following goals:
    • To measure and determine total kVAr needed by each load for optimal Reactive Energy Correction;
    • To estimate possible kWh savings that could result from reducing Distribution System Losses that are a factor of total line losses, termination point losses, transformer losses and other distribution system inefficiencies that we have observed to be prevalent. Potential for kWh energy reduction: 8% - 10%;
    • To estimate potential for reduction in kVA demand. Potential for targeted kVA Demand reduction:          15% - 18% 
    • To estimate potential for increasing the Power Factor and reduction of billing penalties.

      Targeted PF to average:      96%; Targeted reduction in PF Penalties:    $15,000/yr + 

    • To estimate potential for increase in Distribution System capacity which can be as much as a 20%. This can avoid major capital expenses for electrical distribution system and transformer upgrades;
    • To measure and analyze Total Harmonic Distortion (THD or Harmonics) that could be a cause of wasted energy. This may indicate a need for a more detailed Power Quality Study to determine root causes and save more on energy and operating costs.
  1. To identify possible energy-saving measures and strategies available for implementation: -   Compressed Air System improvements can yield 20% to 30% savings; -   Chiller and HVAC System optimization can yield 20% to 30% savings; -   LED lighting fixture upgrades and light management systems can save up to 90%. 
  2. To develop a cost/benefit analysis and determine ROI and Net Present Value for possible energy conservation measures and projects.
    Targeted ROI:                             50% Targeted Payback:                   24 Months before Incentives
  1. To analyze potential strategies for implementing a Measurement and Verification (M&V) Plan that will be required to validate energy conservation project savings. Ideally, we would attempt to develop a plan for documenting a standard unit of production that can be indexed to kWh energy intensity (kWh/Unit). Other potential M&V strategies will have to be explored. Installation of a Smart-Metering system would allow for more targeted and accurate M&V.
