Energy consumption in buildings and industries has become a major concern in the present times. Therefore, identifying ways to manage energy has remained a preferred area of inquiry for researchers. The implementation of energy management systems not only saves electricity in companies but also records their electrical consumption data.

What Does an Energy Management System Mean?

This is a data logging system that helps optimize electricity usage by including various intelligent wired networks of energy meters and other important functionalities. The traditional energy management system manages, records, and monitors the data obtained by energy meters in order to analyze it.

Why is Energy Saving So Important?

Technical advancements in buildings are occurring day by day due to which the energy demand has also risen to the peak. Recent statistics claim that energy consumption in its totality will increase by nearly 48 percent by 2040. In addition, industries have been constantly trying to achieve a reduction in energy costs, however, the lack of energy management is prone to facing failures in terms of energy and cost saving.

The Need for EMS in Organizations

The impressive cost-saving and energy-saving results have obtained attention in the technology sector. By introducing energy management systems in industries, it can lead to saving nearly 20% of energy usage expenditure. As such, in order to fulfill the rising demands of energy in industries, the appropriate application of IoT-based technology is a win-win solution, eventually managing energy consumption smartly.

What are the Primary Functions of EMS?

EMS fulfills primarily three functions

  1. Firstly, it records energy consumption data
  2. Secondly, it analyzes the data and makes a decision
  3. Finally, it implements the formed decision for ultimate energy saving.

Energy Management Subsystems

Organizations have divided EMS into many subsystems that help them fulfill basic functions. This categorization of subsystems helps companies achieve an effective energy management control system. These subsystems can further be used to make hourly, daily, weekly, monthly and yearly reports to optimize energy usage. These are as follows:

  1. Measuring subsystem: this EMS notes daily activities displayed by remote energy meters. After noting down the data, it displays the same through a graphic user interface in multiple formats like trends, gauge view, and many more.
  2. Communicating subsystem: this enables communication between the computers mounted in the control room and energy meters mounted in the field.
  3. Analyzing subsystems: after retrieving data from energy meters, this subsystem helps manage data in a proper way, ultimately making it suitable for easy interpretation. This early interpretation of energy consumption also endeavors to form early decisions.

Aims to Design an EMS

Recently, industries are focusing on EMS for optimum energy output with cost-effective measures. However, there are numerous points to be considered while building energy management systems to precisely monitor the electrical parameter of the load.

  1. To assess and confirm the increase and decrease in energy consumption.
  2. To plan multiple trends of energy usage depending on seasonal, weekly, custom, and operation basis.
  3. To examine the approaching trends and modifications in energy consumption due to constant and long-term changes in business plans.
  4. To investigate particular places wastes huge amounts of energy in order to get an early diagnosis.
  5. To set and formulate targets for an energy management strategy.
  6. Not believe in energy consumption expenditure as a fixed cost; however, identifying ways to reduce the economic burden created by it.

Proposed Objectives to be Achieved by the Established EMS

  1. Specific recording and measurement of energy consumption.
  2. Understanding the relationship between the measured energy consumption and the final product or outcome.
  3. Application of set targets for the reduction in energy consumption.
  4. Accuray checks must be done regularly.
  5. Allocation of energy costs to the specific departments.

To sum up, improvement in energy saving and in the organization can bring about a positive change in operational performance. Energy management systems contribute an important role in completing this objective. There are plenty of benefits that necessitate the application of technology-based advancements in the form of EMS. Firstly, it saves energy, reduces operational expenses, predicts energy consumption, and maintains the budget accordingly. Secondly, it helps reduce the excessive amount of greenhouse gas emissions, ultimately protecting the environment. Combinedly, these positive changes in energy management control systems minimize energy consumption and maximize overall productivity.
