Justin Okpe, Senior Consultant at Verco supports manufacturing clients with providing data driven analysis, identifying energy and carbon reduction opportunities. In this article, he outlines how regression analysis supports accurate savings and helps set reduction targets.

Regression analysis

Regression analysis is a statistical method to understand the relationship between variables. Evidently, It can be a valuable tool to help to plan ahead and set targets.

Energy management in practice

Utilities within manufacturing sites can be complex. A range of different factors can impact the ways a site consumes utilities. There is a challenge with benchmarking improvements on site if operations are constantly changing in the same timeframe.

An example where regression analysis could be useful on site:

Site consumption with a high electricity demand for cooling will vary based on ambient temperature across the year, it can also significantly change year to year, consequently creating a risk with quantifying savings.

Regression analysis can be a powerful modelling tool 

Regression analysis can be a powerful modelling tool to benchmark changes independent of influencing factors. Energy consumption can be predicted by using regression analysis for energy management.

  • A reduction target could be set as an expectation to save on consumption, however it is made difficult to achieve these targets if production levels increase.
  • Setting a target based on a regression model accordingly can account for operational changes. It can also benchmark the true impact of corrective actions completed by site.
  • Management can be informed of what is realistically achievable.

Carbon Desktop has an in-built regression tool

Developing regression models can be a time-consuming task and can require multiple iterations to achieve a robust model.  Carbon Desktop features an in-built regression tool that guides users by simplifying the process through visual prompts that can infer the quality of regression model. This also works with other areas of the platform such as reporting, and it can generally be used to automate tracking of consumption against the dynamic target.

Verco can support with developing regression models through the Bureau Reporting service.
