Energy Management System

Energy Management Software (EMS) is energy software application which provide utility bill tracking, real-time metering, building HVAC and lighting control systems, building simulation and modeling, carbon and sustainability reporting, IT equipment management, demand response, and/or energy audits. Managing energy can require a system of systems approach. Energy management software provides tools for reducing energy costs and consumption for buildings or communities.

  Energy Management System

EMS collects energy data and uses it for three main purposes: Reporting, Monitoring and Engagement. Reporting may include verification of energy data, benchmarking, and setting high-level energy use reduction targets. Monitoring may include trend analysis and tracking energy consumption to identify cost-saving opportunities. Engagement can mean real-time responses (automated or manual), or the initiation of a dialogue between occupants and building managers to promote energy conservation. One engagement method that has recently gained popularity is the real-time energy consumption display available in web applications or an onsite energy dashboard/display.


Energy efficiency is playing an increasingly important role in industry. Rising energy prices, increasing pressure to improve profitability and the growing awareness for climate protection are important factors giving need to the introduction of an energy management system.

Lack of transparency in infrastructure processes, changing cost centers and heterogeneous system environments make an energy management system with a comprehensive range of interfaces necessary.

Energy reporting is time consuming. In many cases, there is no automatic recording of measurement data and supply contracts cannot be optimally negotiated because of the lack of transparency.

Data Collection

Energy Management Software collects historic and/or real-time interval data, with intervals varying from quarterly billing statements to minute-by-minute smart meter readings. The data are collected from interval meters, Building Automation Systems (BAS), directly from utilities, directly from sensors on electrical circuits, or other sources. Past bills can be used to provide a comparison between pre- and post-EMS energy consumption.

Electricity is the most common utilities measured, though systems may monitor steam, petroleum or other energy uses, water use, and even locally generated energy. Renewable energy sources have contributed to the spurred growth in EMS data collection markets.


Reporting tools are targeted at owners and executives who want to automate energy and emissions auditing. Cost and consumption data from a number of buildings can be aggregated or compared with the software, saving time relative to manual reporting. EMS offers more detailed energy information than utility billing can provide; another advantage is that outside factors affecting energy use, such as weather or building occupancy, can be accounted for as part of the reporting process. This information can be used to prioritize energy savings initiatives and balance energy savings against energy-related capital expenditures.

Bill verification can be used to compare metered consumption against billed consumption. Bill analysis can also demonstrate the impact of different energy costs, for example by comparing electrical demand charges to consumption costs.

Greenhouse gas (GHG) accounting can calculate direct or indirect GHG emissions, which may be used for internal reporting or enterprise carbon accounting.


Monitoring tools track and display real-time and historical data. Often, EMS includes various benchmarking tools, such as energy consumption per square foot, weather normalization or more advanced analysis using energy modeling algorithms to identify anomalous consumption. Seeing exactly when energy is used, combined with anomaly recognition, can allow Facility or Energy Managers to identify savings opportunities.

Initiatives such as demand shaving, replacement of malfunctioning equipment, retrofits of inefficient equipment, and removal of unnecessary loads can be discovered and coordinated using the EMS. For example, an unexpected energy spike at a specific time each day may indicate an improperly set or malfunctioning timer. These tools can also be used for Energy Monitoring and Targeting. EMS uses models to correct for variable factors such as weather when performing historical comparisons to verify the effect of conservation and efficiency initiatives.

EMS may offer alerts, via text or email messages, when consumption values exceed pre-defined thresholds based on consumption or cost. These thresholds may be set at absolute levels, or use an energy model to determine when consumption is abnormally high or low. More recently, smartphones and tablets are becoming mainstream platforms for EMS.


Engagement can refer to automated or manual responses to collected and analyzed energy data. Building control systems can respond as readily to energy fluctuation as a heating system can respond to temperature variation. Demand spikes can trigger equipment power-down processes, with or without human intervention.

Another objective of Engagement is to connect occupants’ daily choices with building energy consumption. By displaying real-time consumption information, occupants see the immediate impact of their actions. The software can be used to promote energy conservation initiatives, offer advice to the occupants, or provide a forum for feedback on sustainability initiatives.

People-driven energy conservation programs, such as those sponsored by Energy Education, can be highly effective in reducing energy use and cost.

Letting occupants know their real-time consumption alone can be responsible for a 7% reduction in energy consumption.

When doing this, the existing energy saving potential must be identified and optimization options precisely analyzed. The potential measures are then evaluated and implemented with products, systems and solutions from our extensive portfolio.

Energy Management System (EMS), distributed PC based data acquisition and monitoring software tool used to check the performance of electric utility grids to monitor and optimize the performance of the generation and/or transmission system.

This system used in any organization to achieve energy efficiency through well laid out procedures and methods, and to ensure continual improvement, which will spread awareness of energy efficiency throughout an entire organization. The system will collect all electrical data like Voltage, Amps, Power factor, peak demands from multifunction meters that enables necessary actions and correction at right time.

It is a Client Server based EMS; user can access the data online or offline and even generate the reports from any PC in Local Area Network. There are four different modules available in the system and called as Configuration, Online, Data log and Reports. Data acquisition is possible in six different means

  • Serial communication using data cable.
  • Ethernet communication using LAN cable.
  • Wireless communication using RF modems/Ethernet bridges.
  • Remote data collection using Ethernet gateway (Static IP is required).
  • Remote data collection using GSM/GPRS.
  • Fiber Optics data communication for long distance.

Data acquisition can be distributed for 8 different ports (Either Serial ports or TCP/IP or combination of serial and TCP/IP) so that user can achieve better polling rate. The software is designed to collect the data from network of small, medium and large number of meters i.e. 1 to 512 meters can be configured in the System. Here there is no restriction on data collection from the meters; all the parameters available in the meters are recorded.

User configurable data recording time interval (1 minute to 60 minutes). All the abnormality will be recorded in the Alarm option in the software and this will be recorded in terms of seconds. Database backup and restore option is also available in the software.Grouping and sub grouping is another feature of this software.

There are many screens of online data representation available in the software. These are all parameters for the selected meters, Group of meters data, all the meters data, trends of six different parameters for the selected meter, trends of single parameter for any six meters, Trends for any four parameter/meters, Analog meter view and meter Line diagram.

Data log module is used view the historical data and trends. One of main feature is export data to excel or text file so that user can utilize the data as per their requirement. Data comparison of selected parameter for any selected six meters is also available in the data log. By selecting points in the trend chart user can read the data values with time stamp.

Report module enables the user to generate different types of reports. Some of the available reports are Data log report, Parametric report, Min/Max report, Outage (No. of power interruption) report, Alarm report. Energy consumption of Hourly, Daily, weekly, Monthly, Yearly, Shift wise, TOD wise and Group wise report is a part of Report module. Some of these reports are generated with bar, line and pie charts. Monthly Maximum Demand (MD) report shows the daily MD with time stamp.

Software can be programmed for the automatic reset of MD reading in the meter daily or monthly. Production data can be fed to the software for any selected meter, this will help to generate the specific energy consumption reports.
