Power management and energy management: The difference, the overlaps and the evolution

What is the difference between power management and energy management?

Power management is an integrated system that consists of power meters, power management software, and power quality mitigation equipment. If you think from a purpose perspective, it is largely about the enhancement of electrical reliability or even availability. Keep in mind that power availability, quality, reliability, and manageability are key ingredients for a power building.

Energy management is related to saving cost, and it then blends with the existing energy-related streams which analyses the power distribution systems across all energy-related aspects of a building (keeping the aforementioned things in mind).

Cost savings is one of the crucial aspects of the BEMS market, which is transforming in this age of IoT, and so is the role of building management systems, the possibilities with regards to critical power buildings, and so forth.

If power management mainly aims to ensure power or electrical reliability and availability on one hand and energy management, among others, aims to realize cost savings, then how do they impact each other, if they do, at all?

Where do power management and energy management overlap?

It all boils down to you wanting basic things such as reliability, availability, quality, and efficiency and cost savings. However, there are a few unexpected costs that come along when you implement an energy-saving solution or even energy-saving measures, which can lead to a negative impact on the electrical network or reliability.

All of us being so fascinated by technological evolutions like IoT, and also the role of buildings and smart buildings has reached another level. And, things don’t stop here. We are inclined towards energy-efficient building technologies. The challenges faced by society and businesses trying to understand the difference between power management and energy management, and how they are evolving and are being used.

In simple words, you would never go as far as wondering what the unexpected impact of an energy-saving measure could be or let us say the electrical reliability or even the unexpected costs that it might bring along. Still, the professionals that work in facility management, building automation, critical power, energy management, and so forth obviously have to wonder about the energy-saving measure they will have to take.

Following are the three takeaways that you can derive from the post:
  • In unique and specific cases of LED lighting (energy saving), it has the potential to impact power quality. So, when you are planning an LED lighting project, make sure you know—when and how.
  • The issues that you face during the identification of power quality are, for instance, LED lighting, they become a standard expectation with regards to building management systems today (whereas PQ before was mainly an issue in an industrial or critical power environment).
  • Moreover, with the BMS system becoming the digital hub of connectivity in the building, power management, PQ, and monitoring harmonics come into that connected equation as well – with it having an impact on the skills of BMS experts.
