Quick Answer:<\/b> A business should build an energy management system that focuses on continuous feedback and improvement. Rather than building an energy management dashboard, it should build a closed improvement loop that collects accurate data from meters and equipment, detects patterns of energy waste and consumption behavior, recommends or automates energy-saving steps, evaluates the improvement, and repeats the same cycle.\r\n<\/p>\n <\/div>\n \n\n\n\n

While many enterprises take stringent measures to reduce energy consumption costs and meet sustainability commitments, they still rely on the monthly utility bill as their sole source of energy information. Energy bills don\u2019t offer much help in managing energy consumption. <\/p>\n\n\n\n

This is where an efficient and smart energy management system<\/strong> (EMS) comes into play. An EMS solution doesn\u2019t just show a cost overhead. Still, it presents a comprehensive picture of energy management by connecting meters, sensors, building-management systems, production equipment, utility bills, and renewable-energy assets. <\/p>\n\n\n\n

This guide explains how to build an energy management system for businesses<\/strong>, how to prioritize the build pipeline, when to buy a solution instead of developing it, and how to measure the value delivered by an EMS solution.<\/p>\n\n\n\n

What Is an Energy Management System for Businesses?<\/h2>\n\n\n\n

An energy management system is a coordinated platform for people, processes, control mechanisms, data, devices, and software to track energy performance and recommend improvement measures. In tech terms, it is commonly referred to as energy management software<\/strong> or an energy management information system (EMIS). <\/p>\n\n\n\n

In EMS-equipped enterprise environments, an EMS generally handles 6 closely connected tasks: <\/p>\n\n\n\n

    \n
  1. Measure:<\/strong> Collect consumption and usage data on electricity, gas, steam, water, fuel, generation, and equipment.<\/li>\n\n\n\n
  2. Bring context:<\/strong> Bring context to the usage based on variable factors such as weather, production volume, occupancy, schedules, tariffs, and maintenance events.<\/li>\n\n\n\n
  3. Usage benchmarking:<\/strong> Create appropriate consumption baselines for sites, departments, processes, and assets and track performance against the same.<\/li>\n\n\n\n
  4. Fault-line & anomaly detection:<\/strong> Detect data anomalies, energy wastage patterns, faults, peak-demand events, and energy control issues.\u00a0<\/li>\n\n\n\n
  5. Recommendation & implementation:<\/strong> Based on performance benchmarks and detected issues, make recommendations, issue work orders, schedule repairs, change consumption limits, and implement automated controls.<\/li>\n\n\n\n
  6. Impact evaluation & improvement:<\/strong> Finally, evaluate the ROI impact and energy savings, document the results, and set new targets and practices for further improvement.<\/li>\n<\/ol>\n\n\n\n

    Essential Energy Management Software Features<\/h2>\n\n\n\n

    It\u2019s important to have a detailed idea of the energy management system software<\/a><\/strong> features before building it. Here\u2019s a list of key features.\u00a0<\/p>\n\n\n\n

    Real-Time Energy Tracker<\/h3>\n\n\n\n

    A tracking dashboard should display data and statistics on current power supply, cumulative consumption, demand, cost, and electricity supply status for each site, system, and asset in a business premises. It should mention consumption units and data for different time ranges, along with a comparison table and actionable suggestions. <\/p>\n\n\n\n

    Historical Trend and Gap Analysis<\/h3>\n\n\n\n

    EMS should allow users to check energy usage trends across different timeframes, seasons, production periods, weather conditions, and operating schedules. From a summary section, users should be able to drill down into the exact readings of any meter and corresponding time period. <\/p>\n\n\n\n

    Energy Baselines & Indicators<\/h3>\n\n\n\n

    Every EMS should fix energy baselines for different departments, seasons, and processes to compare energy performance. Energy performance indicators show the actual performance of each department, process, or season based on this baseline. An elementary energy baseline can be a historical energy consumption average. <\/p>\n\n\n\n

    Comparative Benchmarking and Portfolio Management<\/h3>\n\n\n\n

    An EMS solution should have a comparative benchmarking feature to compare energy figures against one another across different timeframes. The key here is to benchmark similar sites and include floor area, climate, operating hours, production, occupancy, and other material drivers in the comparison. <\/p>\n\n\n\n

    Tariff and Cost Analytics<\/h3>\n\n\n\n

    Instead of using a flat one, an EMS should rely on the actual tariff structure for cost calculation and analysis. The cost calculation should take into account rates for specific time of use, high-demand surcharges, ratchets, taxes, fixed charges, export compensation, etc. EMS should use a version control system for the cost model to keep track of tariff changes. <\/p>\n\n\n\n

    Automated Fault Diagnostics<\/h3>\n\n\n\n

    The EMS should have an automated fault detection and diagnostics feature to compare operational energy data with expected usage behavior. For example, automated diagnostics will track energy consumption by a building outside its schedule, or unusual cooling cycles of a refrigerator. <\/p>\n\n\n\n

    Integrated Alerts and Escalation<\/h3>\n\n\n\n

    Based on severity, the EMS should trigger alerts to reduce business impact. It should be designed to ensure quick escalation and faster response time to minimize detrimental impact. It should also establish accountability with a clear escalation path. The alert system should allow acknowledgement, task assignment, comments, attachments, resolution codes, and fault analysis.<\/p>\n\n\n\n

    Demand Forecasting<\/h3>\n\n\n\n

    An EMS is not just an energy consumption monitoring software, but it packs a powerful demand forecasting solution as well. Demand forecasting helps manage sudden demand spikes by planning energy supply and infrastructure revamp well in advance. The forecast analysis over time will help the EMS detect predictable demand and usage patterns. Finally, the demand forecasts should trigger a response workflow with details of the alert, accountable personnel, permissible energy loads and technical constraints, expected value, and a rollback mechanism.<\/p>\n\n\n\n

    Renewable Energy Integration<\/h3>\n\n\n\n

    Modern EMS should track renewable energy supply, consumption, and demand. The EMS should have a dedicated module to track and compare renewable energy consumption and infrastructure gaps against the traditional energy ecosystem. <\/p>\n\n\n\n

    Reports & Audit Trails<\/h3>\n\n\n\n

    The EMS should create and send detailed reports on energy operations, finance, sustainability, and energy infrastructure management. Every reported figure should leave a precise audit trail covering the data source, changes, assumptions, and underlying cost model version.<\/p>\n\n\n\n

    How to Build an Energy Management System: a Practical Roadmap<\/h2>\n\n\n\n

    Now that you have a fair idea of the must-have EMS features and how they work, let\u2019s get down to actual steps for energy management software development<\/strong>. <\/p>\n\n\n\n

    Phase 1: Discovery and Use Case<\/h3>\n\n\n\n

    This foundational stage lets you review and assess the existing energy infrastructure and its current state. Start by reviewing energy bills, inspecting current energy-saving and control tools, and interviewing users. Create all the baselines and energy benchmarks across departments, processes, and timeframes. Lastly, map all data sources and the actionable steps with the highest impact. <\/p>\n\n\n\n

    Conclude this phase by documenting target metrics, priority sites, energy assets, data sources, risk assumptions, and a decisive argument for custom in-house development against buying a SaaS product or choosing a hybrid delivery option.<\/p>\n\n\n\n

    Phase 2: Build Data Foundation Based on Energy Readings<\/h3>\n\n\n\n

    Build the data foundation of an EMS based on energy readings of the main meter and some high-value submeters. For the measurement plan to work, follow a naming convention for units, time zones, asset IDs, and quality parameters. <\/p>\n\n\n\n

    Phase 3: Build the EMS MVP<\/h3>\n\n\n\n

    Now build the minimum viable product<\/a><\/strong> (MVP) version of the EMS software. An MVP version or the first EMS release should include the following features and components:\u00a0<\/p>\n\n\n\n
