Mahidol University Energy Management
Electricity consumption at Mahidol University supports a wide range of essential activities, including education, research, medical services, and other university operations. These activities result in a high level of annual energy consumption. Mahidol University is focused on energy management to ensure effective and sustainable energy use. The university aims to reduce energy waste and promote the reduction of greenhouse gas emissions. Efforts are directed towards minimizing energy waste, lowering emissions, and encouraging the adoption of renewable energy sources. Additionally, Mahidol University incorporates energy-efficient technologies into its operations, fostering a sustainable campus that aligns with the United Nations Sustainable Development Goals (SDGs), particularly Goal 7: Affordable and Clean Energy, and Goal 13: Climate Action.

Solar Energy
Mahidol University has established sustainability management strategies to drive and advance the university’s operations toward environmentally and socially friendly practices in an effective and sustainable manner. The university has set up guidelines and measures for building energy management to ensure efficient energy use and reduce electricity costs. Since 2010, Mahidol University has been installing solar energy systems on the rooftops of its buildings as part of these efforts, as outlined below.

In 2022, Mahidol University Salaya implemented the installation of solar energy systems with a total peak generation capacity of 12.25 megawatts (MW) across rooftops and water surfaces. The electricity generated by these systems is utilized to power various electrical systems and devices within campus buildings, including HVAC (Heating, Ventilation, and Air Conditioning) units, computer systems, and lighting fixtures. When the solar energy systems produce electricity exceeding the demand of a specific building, the surplus energy is redistributed to other buildings across the campus. This approach optimizes the use of renewable energy resources. The solar power systems became operational in November 2023.

Currently, Mahidol University has installed a total solar energy capacity of 14.91 megawatts (MW), which generates an average of 1,336,500 kilowatt-hours (kWh) of electricity per month. This initiative also contributes to reducing greenhouse gas emissions by approximately 650 tons of CO 2 equivalent (Ton CO 2 e) per month. Additionally, the university plans to expand its solar energy capacity by 7.19 MW across the university.

Energy Management System
Mahidol University Salaya has implemented an Automatic Meter Reading (AMR) system that allows real-time monitoring of electricity consumption across campus buildings through SCADA (Supervisory Control and Data Acquisition) systems. A website has also been developed to display energy usage data for each building, enabling detailed analysis for effective energy management. This system helps track energy loss and identify opportunities to reduce energy consumption, ensuring that buildings operate at maximum energy efficiency. Users can easily access electricity consumption data through the website, facilitating efficient management.

Energy Management within Buildings
At the Office of the President Building and the Mahidol Learning Center, an energy management program has been established to limit the maximum electricity demand to 500 kW. Air conditioning systems are controlled by automatically cutting off the electrical circuit to the compressor when the demand exceeds 500 kW for a short period (between 3-5 minutes). This helps manage and reduce peak demand while maintaining the room temperature between 22-25°C, ensuring sustainable energy efficiency within the buildings.
Energy-Efficient Equipment
Mahidol university utilizes energy-efficient equipment, such as computers, printers, light bulbs, and air conditioning units, which consume less electricity or offer higher performance. Currently, 85.6% of the equipment used on campus is energy-efficient.
