ISO follows the Deming cycle (plan-do-check-act) to help organizations plan, implement, maintain and improve an Energy Management System (EnMS). For large energy using organizations, energy data is most often managed in an Energy Management Information System (EMIS). In a previous article EnMS and EMIS: What’s the Difference?, Dr. Paul Monaghan and I described the outputs of an EMIS and the benefits that those outputs bring to a complete EnMS.
In this short article we primarily focus on “Energy Planning” and the key steps necessary to allow for correct checking of energy performance. The EMIS outputs can again be utilized, but we will focus on what outputs to use and how to use them?
Working with a customer a few weeks CG Leads back, I had asked them to identify their significant energy uses (SEUs). I had also asked the customer in parallel to consider what energy metering data they wanted to assess.
When I received the list of SEUs and the list of meters, there was no obvious link between them. This surprised me, because the customer had detailed metering data for their whole site, knew from experience what their SEUs were, but still the meters did not match up to their SEUs!
I asked the customer to think “What do I want to achieve from the data that I am collecting?” I wanted them to realize that they needed the energy data to check energy performance monitoring to help their organization to set realistic and achievable objectives and targets.
They believed their organization possessed all of the metering data they could ever need. This is a great starting point, but I explained that, we needed to start by reverse engineering, i.e. from the top down! That is: the ISO mind-set.
So, I went about explaining energy data management for ISO . After a few minutes the customer had a “eureka” moment and stopped me, saying, “I get it! This is thinking on a higher level.”
The figure below describes the key steps that I told the customer to consider, along with what questions to ask at each step and some example answers to those questions.
