How To Prepare The Electrical Load Schedule As Per DEWA Standards And Regulations

Preparing an electrical load schedule per the guidelines and regulations set by the DEWA(Dubai Electricity and Water Authority) ensures the safe and efficient operation of electrical systems in Dubai.

The regulation concerns the standard ,applicable to all electrical installations within or around buildings, including any modifications, expansions, or enhancements to existing structures and their associated electrical systems in the Emirate of Dubai.

For projects necessitating the construction of high-voltage substations, it is essential to consult with DEWA Approved electrical services during the initial design phase to incorporate any specialised requirements.Through this article, we intend to give insight into preparing the electrical load schedule as per DEWA standards and regulations.

  • Familiar with the DEWA Standards

Anyone participating in electrical and water-related projects in the Emirate of Dubai must be familiar with DEWA (Dubai Electricity and Water Authority) requirements. To ensure the secure, effective,  and long-lasting use of water and energy.

  • Gather Key Details

To properly schedule electrical loads, it is important to identify and keep track of all the documents, equipment, and electrical devices that will be coupled to the electrical network. Each connected load, including appliances, lighting, machinery, and specialised equipment, is evaluated as to its power needs and other characteristics. 

  • Determine specific loads

When analyzing the power demands for each connected load in an electrical system, a meticulous process is essential. This involves a thorough examination of machinery, appliances, or electrical devices to ascertain their specific power needs. Factors such as voltage, current, power factor, and operational hours are taken into consideration to determine the load requirement for each component. This careful analysis ensures an accurate assessment of power demands for optimal system design and efficiency.

  • Implement Diverse Load Adjustments

Incorporating diverse load adjustments is considered a vital step in load calculation and electric system design. Various load utilisation patterns are recognized, and appropriate adjustments are made to optimise the electrical system’s capability in handling fluctuating demands effectively. 

By implementing necessary modifications, irregular demands from specific appliances can be adeptly managed by the electrical infrastructure without risking overload during peak usage periods. This strategic approach contributes to the enhancement of the system’s efficiency and overall performance.

  • Understanding demand factors

Another vital step involved in effectively estimating the maximum demand on an electrical system is the determination of demand variables. Demand factors describe the anticipated simultaneous functioning of all loads at their peak and are multipliers applied to the calculated load of a specific circuit or device. These variables are chosen based on previous usage statistics, statistical research, and market understanding. Demand factors provide a more accurate prediction of the system’s overall demand by considering the chance that not all loads will run simultaneously at maximum demand. 

  • Proper structure of the load schedule sheet

Creating the load schedule sheet is one of the most essential aspects of electrical design and planning. It entails gathering and organising all of the obtained information, computations, and analyses about the electrical loads. 

Details like load categories, connected loads, demand loads, diversity factors, demand variables, and any other pertinent information are frequently included in the load schedule document. It serves as a thorough reference and offers a concise breakdown of the project’s overall electrical load requirements.


In any building or renovation project, creating an electrical load schedule that complies with DEWA regulations is a challenging but essential procedure. A secure, effective, and sustainable electrical system is guaranteed by following dewa approved contractors rules by adhering to the electrical load schedule that complies with requirements by carefully following the instructions in this guide and working with experts familiar with DEWA standards.
