What is DG Efficiency<\/span><\/strong><\/h2>\n

DG Efficiency stands for Distributed Generation Efficiency. Fuel is the major portion of diesel Genset, owning and operating cost for power applications. Modern diesel plant, at its near-optimal loading ( 65- 70%) generate 3.3 to 3.5 kWh per litre. That is a 30% fuel efficiency ratio.<\/span><\/p>\n

What is DG in Electrical?<\/h2>\n

DG in electrical stands for Diesel Generator, which is a power backup system used to generate electricity during power cuts or interruptions in the main power supply. It converts diesel fuel into electrical energy and helps maintain uninterrupted operations in commercial buildings, factories, hospitals, data centers, residential complexes, and corporate offices. DG sets are especially important for facilities where continuous power supply is critical for equipment, security systems, lighting, elevators, HVAC systems, and daily operations.<\/p>\n

A Diesel Generator mainly consists of an engine, alternator, fuel system, battery, cooling system, and control panel. When a power outage occurs, the DG automatically or manually starts generating electricity and supplies backup power to connected systems. Facility managers regularly monitor DG performance, fuel consumption, running hours, load capacity, and maintenance schedules to ensure efficient operation and avoid unexpected breakdowns. Modern DG monitoring systems also provide real-time alerts, automated reporting, and performance tracking for better energy and facility management.<\/p>\n

Why measure DG Efficiency?<\/span><\/strong><\/h2>\n

Whether it is an office space, shopping mall, corporate park, or a residential society, you can not find any property without Power Back up.<\/span><\/p>\n

As saying goes, if you want to improve anything, start measuring that.<\/span><\/p>\n

Reasons to improve efficiency<\/span><\/strong><\/h3>\n

Higher efficiency means low cost, higher productivity. Few reasons, DG efficiency needs to be improved:<\/span><\/p>\n

    \n
  1. Lower Cost:<\/strong> Fuel, is a scarce resource, costly, and needs to be used intelligently.\u00a0<\/span><\/li>\n
  2. Environment Friendly<\/strong>: More efficient is our DG, lesser the pollution generated by it.\u00a0<\/span><\/li>\n<\/ol>\n

    And it is always better if we can measure and track the efficiency in real-time.<\/span><\/p>\n

    \"what<\/a><\/p>\n

    How you measure your DG Efficiency?<\/span><\/strong><\/h4>\n

    A diesel generator<\/b>\u00a0(also known as diesel genset) is the combination of a\u00a0diesel engine<\/a>\u00a0with an\u00a0electric generator<\/a>\u00a0(often an\u00a0alternator<\/a>) to generate\u00a0electrical energy<\/a>.<\/span><\/p>\n

    How to calculate DG Efficiency<\/span><\/strong><\/h4>\n

    In simple terms:<\/span><\/p>\n

    Another Way to calculate DG efficiency is:<\/span><\/p>\n

    British Thermal Units ( BTU)<\/a><\/span><\/h3>\n

    IoT Edges and AI<\/span><\/strong><\/h3>\n

    Any CAFM<\/a>, CMMS<\/a>, or Asset Performance Monitoring system can show the DG efficiency in real-time. This can be achieved by any of the below approaches.<\/span><\/p>\n

    Integration with Building Management System<\/span><\/strong><\/h4>\n

    If you have already a DG controller installed, then CAFM system can be integrated easily with your existing DG controllers, which can then run analytics to give you insights into your DG<\/span><\/p>\n

    IoT Sensors ( Edges)<\/span><\/strong><\/h4>\n

    Another way is to install IoT sensors at the DG Control Unit to track output and another sensor on the diesel Tank. Any good CAFM system will provide the integration points with the IoT Edges.<\/span><\/p>\n
