Use of average energy intensity can hide savings or show fake savings

A common way to determine energy intensity in manufacturing is to divide energy cost by production volume, resulting in kWh per car or m3 per pound of bread. This simplistic approach may hit energy manager where it hurts the most - at evaluation of completed projects. A good well-implemented project may show dismal savings [...]

Baseline formula must reflect process, not the data collected

When determining energy consumption baseline through regression analysis, as recommended by best practices, sensible energy managers pick a formula that relies of physics of the process, not a formula that produces high correlation (R2) between predicted and measured data. In vast majority of cases relation between energy consumed and it's driver is linear. Here [...]

Use of average cost per kWh hides savings from CFO

Use of average electricity cost can be misleading when assessing financial impact of energy efficiency measures. What counts is the cost of the last kWh comprised of Global Adjustment (Ontario), demand charges and energy cost. If average cost per kWh is used during project approval, it may become a challenge to show savings to [...]

In energy management time is of the essence

If your plant underproduced today, you may be able to catch up with schedule by working overtime tomorrow. If you wasted energy today, it is gone forever. No effort tomorrow will help to recover it. Timely action is the key to stop waste before it became to big. Do you know how much energy [...]

Electrical bills come too late to act

Monthly electrical bill is as good for energy management as a summary of monthly bank statement is for financial management: too little of data to understand what happened and too late to act. Summary of bank statement shows balance of account: sum of deposits and sum of payments. If you have spent too much or received [...]

5 simple steps to decide if it’s time to recommission

Performance of every piece of machinery degraded with time. This may cost your plant thousands of dollars in lost production, rejects, and energy. Recommissioning can solve this problem, but it costs time and money. When is recommissioning worth the effort? Energy costs of performance degradation Degradation may be caused by a wide range of [...]

Energy submetering by itself is useless and how to make it work

Automatic data collection, purposeful analysis and alert on deviations to appropriate people is a key to sustained energy cost savings.

Why Global Adjustment avoidance assets may turn into stranded assets and how to avoid this

Companies that buy new equipment to avoid Global Adjustment charges face risk of having stranded assets. Business case for investments in GA avoidance equipment - generators and batteries - relies on current GA model, which resulted from a political decision. GA regime is based on politics, which are reliably unreliable As we all know, [...]

How much energy your freezer wastes?

I can't say how much energy your freezer wastes. I do not have a crystal ball, but we saw a few freezers at other companies and I have condensed our observations in a short mock Q&A with a plant manager: Q. Might our freezers work at their best efficiency? A. Yes, it is possible. [...]

5 golden rules of energy data analysis

  1. In metering we trust :)    Data is only reliable if it has been collected through routine automatic metering, which has been validated.  All claims like 'we always keep this operational schedule', 'compressor/boiler/light is off on weekend' or 'current never exceeds X Amp', all of them have exactly zero value to energy [...]
