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 the highest correlation (R2) between predicted and measured data. In a vast majority of cases relation between energy consumed and it's driver is [...]

Use of average cost per kWh hides savings from CFO

By |2020-10-13T15:22:55-04:00September 30th, 2020|Categories: Energy management|Tags: , , , |0 Comments

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.

Are energy meters like birdhouses or like screws?

By |2020-06-03T10:33:14-04:00May 19th, 2020|Categories: Energy management, Energy management education|Tags: , , , |0 Comments

It occurred to me that meters relate to energy monitoring in the same way as screws relate to birdhouses. How is that? Some manufacturing plants start energy management from installation of meters. Too often the process ends with meters too. However costly, this result is predictable. I will explain why on an example of [...]
